Shut-off valve

This type of valve is used for opening and closing. It is permanently installed on the inlet and outlet of cold and heat sources, the inlet and outlet of equipment, and branch lines of pipelines (including standpipes). It can also be used as a water discharge valve and air release valve. Common shut-off valves include gate valves, globe valves, ball valves and butterfly valves.
Gate valves can be divided into bright rods and dark rods, single gates and double gates, wedge gates and parallel gates, etc. The closing tightness of the gate valve is not good, and it is difficult to open the large-diameter gate valve; the size of the valve body is small in the direction of water flow, the flow resistance is small, and the nominal diameter span of the gate valve is large.
Globe valves are divided into three types: straight-through type, right-angle type and straight-through type according to the flow direction of the medium, and there are bright rods and dark rods. The closing tightness of the globe valve is better than that of the gate valve, the valve body is long, the flow resistance is large, and the maximum nominal diameter is DN200.
The spool of the ball valve is a ball with a hole. When the plate moves the valve stem so that the opening of the ball is facing the axis of the pipeline, it is fully open, and when it is turned 90°, it is fully closed. The ball valve has a certain adjustment performance and is more tightly closed.
The valve core of the butterfly valve is a circular valve plate, which can rotate along the vertical shaft perpendicular to the pipeline axis. When the plane of the valve plate is consistent with the axis of the pipe, it is fully open; when the plane of the gate plate is perpendicular to the axis of the pipe, it is fully closed. Butterfly valve body length is small, flow resistance is small, and the price is higher than gate valve and globe valve.

check valve

This type of valve is used to prevent the medium from flowing backwards. It uses the kinetic energy of the fluid itself to open itself and closes automatically when it flows in the reverse direction. It is always installed at the outlet of the water pump, the outlet of the steam trap and other places where the reverse flow of fluid is not allowed. There are three types of check valves: swing type, lift type and wafer type. For the swing check valve, when fluid can only flow from left to right, it will automatically close when it flows in the opposite direction. For the lift check valve, when the fluid flows from left to right, the valve core is lifted to form a passage, and when the fluid flows in the reverse direction, the valve core is pressed against the valve seat to be closed. For the wafer check valve, when the fluid flows from left to right, the valve core is opened to form a passage, and when the fluid flows in the opposite direction, the valve core is pressed to the valve seat to be closed. Installation, small size, light weight, compact structure.

Control valve

The pressure difference between the front and back of the valve is constant. When the opening of the ordinary valve changes in a wide range, the flow rate changes little, but when it reaches a certain opening degree, the flow rate changes sharply, that is, the regulation performance is not good. The regulating valve can change the stroke of the spool to change the resistance of the valve according to the direction and magnitude of the signal, so as to achieve the purpose of regulating the flow of the valve. Regulating valves are divided into manual regulating valves and automatic regulating valves, and manual or automatic regulating valves are divided into many types, and their regulating performance is also different. Automatic regulating valves include self-operated flow regulating valves and self-operated differential pressure regulating valves.

Vacuum class

Vacuum categories include vacuum ball valves, vacuum flapper valves, vacuum inflation valves, pneumatic vacuum valves, etc. Its function is that in the vacuum system, the components of the vacuum system used to change the direction of the air flow, adjust the size of the air flow, and cut off or connect the pipeline are called vacuum valves.

special purpose

Special purpose categories include pigging valves, vent valves, drain valves, exhaust valves, filters, etc.
The exhaust valve is an indispensable auxiliary component in the pipeline system, and is widely used in boilers, air conditioners, oil and gas, water supply and drainage pipelines. It is often installed at commanding heights or elbows to remove excess gas in the pipeline, improve the efficiency of pipeline use and reduce energy consumption.

A fire extinguisher is the most commonly used fire extinguishing equipment for fighting an initial fire. It is a portable fire extinguishing device that can be moved by manpower. And its structure, method of use are all relatively simple. But it is this kind of simple fire extinguishing equipment, there are still various misunderstandings in the fire science education, resulting in that when a fire comes, the fire extinguisher can only be a decoration.

Promote long-obsolete fire extinguishers

Because chemical foam and acid-base fire extinguishers must be used upside down, there is a high risk of instantaneous pressure, they cannot be sprayed intermittently, and their fire extinguishing efficiency is low. Shanghai began to phase them out in the 1990s, and other provinces and cities have also phased them out. The 1211 fire extinguisher was eliminated in our country more than ten years ago due to the problem of destroying ozone gas after the 1211 fire extinguishing agent was discharged into the atmosphere. However, there are many newly issued wall charts and comic books in the society that still promote the use of the above-mentioned fire extinguishers. These contents are obviously redundant now, and sometimes they will mislead the public to use fire extinguishers wrongly.

Promoting Outdated Taxonomies

According to the classification of the fire extinguishing agent filled, the current fire extinguisher classification method divides fire extinguishers into four categories: water-based fire extinguishers, dry powder fire extinguishers, carbon dioxide fire extinguishers and clean gas fire extinguishers. It can be divided into two types: water type fire extinguisher and foam fire extinguisher. However, there are still many fire science publications, and even the newly built fire science education center divides fire extinguishers into four categories according to the old classification method: water fire extinguishers, foam fire extinguishers, dry powder fire extinguishers and carbon dioxide fire extinguishers. This is problematic. Because with the advancement of technology, water-based fire extinguishers generally contain additives to improve fire extinguishing efficiency and expand functions. Now, if the classification method that is behind the times is spread, the audience will not be able to understand and utilize the expanded functions of water-based fire extinguishers.

exaggerated squirt time

The injection time of a 4 kg dry powder fire extinguisher is generally about 18 seconds, and the injection time of the same water-based fire extinguisher is 30-40 seconds. However, in many fire science education bases, the injection time of simulated dry powder and water-based fire extinguishers of the same level is as long as one minute or even more. It is obviously misleading to use such a simulated fire extinguisher to train ordinary people to master the use of fire extinguishers, because the ordinary people who have received this kind of training only find that the fire extinguisher cannot be sprayed for such a long time when a fire breaks out, and it cannot extinguish the expected fire. fire, you will be at a loss.

Extinguish multiple fires with one fire extinguisher

In some fire science education bases, people can often see this phenomenon: a visitor uses a 4 kg simulated dry powder fire extinguisher to extinguish two or even three fire points, and the screen displays “success”, otherwise it is ” unsuccessful”, which is completely misleading. Because the actual situation is that only when the fires at the two fire points are at the minimum 1A (the basic unit of the wood stack in the fire extinguishing test), it is possible for the fire experts to extinguish the two fires with a 4 kg dry powder fire extinguisher If the fire is lit, if one of the fire points is above 2A, the experts will not be able to extinguish it in 18 seconds. The designers of those bases extended the spray time from 18 seconds to 1 minute, so more than 2 fires could be extinguished. Such training is child’s play, doing more harm than good to the trainees.

Although the fire extinguisher is simple, there is a lot of technical knowledge about it. Anyone who wants to spread the knowledge of fire extinguishers and how to use them, no matter in graphic form or in the form of a simulation device, must first learn this knowledge and keep learning new knowledge. . The dissemination of fire science knowledge must be based on science, otherwise it may enter into misunderstandings. The existence of these misunderstandings is not conducive to the correct selection and use of fire extinguishers by the public, and cannot guarantee the safety of people’s lives and property when the crisis comes, and even cause more serious problems. Therefore, it is necessary to get out of the misunderstanding of understanding and publicity, so that fire extinguishers can truly serve the people.
