Here are a few operating procedures for knife gate valves
Several operating procedures of knife gate valve
When the knife gate valve is closed, the sealing surface can only be sealed by medium pressure, that is, the sealing surface of the gate is pressed by the medium pressure to the other side of the valve seat to ensure that the sealing surface of the sealing surface, this is the self-sealing, most of the gate valves are mandatory sealing, that is, when the valve is closed, the gate is pressed against the valve seat with an external force to ensure that the sealing surface of the sealing performance of the sealing performance of the valve should be mounted vertically on the pipeline.
Performance
1. The valve can be controlled locally and remotely according to the user's requirements, and it can also be displayed remotely and centrally.
2. Light weight: the valve body is made of carbon steel, which is about 20% -30% lighter than the traditional gate valve, which is easy to install and maintain.
3. The use of such valves can improve the sealing performance of the pipeline system and prevent leakage to a large extent, which plays a positive role in improving production efficiency and protecting the environment.
4. The sealing surface is designed with high wear-resistant and corrosion-resistant ceramic composite material, using inlay technology, high corrosion resistance, good abrasion resistance, so that the service life of our valves is extended, and the cost-effective than ordinary valves increased by 10 times.
Why does the resistance of knife gate valve change?
1. Knife gate valve
As well as household gas into the cylinder knife gate valve, the standard name of the Chinese national bottled imported liquefied petroleum gas regulator, which is used in thousands of households in society, and our lives are closely related to the safety of the gate valve by regulating the inlet pressure to a certain extent to reduce the outlet pressure, relying on the medium's own energy to maintain a stable outlet pressure automatically.
From the perspective of fluid mechanics, knife gate valve is a local resistance variable throttling element, that is, by changing the throttling area, you can change the fluid flow and kinetic energy, resulting in different pressure losses, so as to achieve the purpose of pressure reduction.
2.Function of knife gate valve
Knife gate valve is a kind of valve that automatically keeps the outlet pressure stable by adjusting the inlet pressure to a certain required outlet pressure and relying on the energy of the medium itself. From the point of view of fluid dynamics, the safety valve is a kind of throttling element, in which the local resistance can be changed, i.e., by changing the throttling area, it can change the flow rate of the fluid and kinetic energy, and produce different pressure losses, so as to achieve the purpose of reducing the stress.
3.Classification of knife gate valve
The pressure in the cylinder is very high, if the cylinder is connected directly to the stove, at first the stove's flame combustion is not stable; second, high pressure is connected directly to the stove, combustion is easy to leak; third, a large amount of gas rushes out to produce a strong flame, a great waste of energy (large flame combustion does not require household gas), combustion of incomplete gas is harmful to human beings.
4. Knife gate valve high pressure, high flow, liquefied gas released into the air without sparks, serious time connected to cause liquefied gas cylinder explosion.
We must pay attention to the knife gate valve of the household gas stove to use JYT-0.6. Import enterprise pressure 1.56Mpa, export market pressure 2800pa 500pa regular knife gate valve operation, which is a kind of non-controllable adjustable knife gate valve.
The company specializes in knife gate valve series products as its own responsibility, the implementation of “unqualified Mao Pei not into the factory, not standard parts are not assembled, do not meet the standard products do not go out” and other quality management policy for customers to solve the worries.
