Fire Slab Gate Valve

Price: The price is changing because of material cost and exchange rate. Please give me your contact information, I will update the newest price to you.

1. It has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy installation and easy disassembly.

2. When the valve is fully opened, the flow resistance coefficient is very small, and the valve will eliminate the function of the valve disc and the dirt on the sealing surface every time the valve is opened and closed.

3. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.

4. It is widely used in oil and water steam pipelines such as petrochemical industry and thermal power plants to connect or cut off the intermediate quality of pipelines. The sealing surface of the opening and closing device has compact structure and reasonable design.

Q: What are the main points of fire valve selection?

A: 1. The main control parameters of fire valve are specifications.

2. Fire valve is suitable for ventilation and air conditioning system, except for the fire valve used in the kitchen exhaust smoke system of public buildings, the operating temperature is 150 ° C, and the operating temperature of the fire valve used in the general ventilation and air conditioning system is 70 ° C.

3. Fire valve is suitable for ventilation, air conditioning or smoke exhaust system on the pipeline, the basic function and scope of application.

4. When selecting the valve, attention should be paid to the function of the valve, such as normally open or normally closed, automatic closing open, manual closing open, manual reset, signal output, remote control and other requirements.

5. If the valve is linked with the fan, it should be used with a double micro-switch device

Q: What is a gasket? What are the requirements for valve gasket materials?

A: On the valve, the gasket is the main seal to prevent the leakage of the medium, which is used to fill all the bumps between the two joint surfaces (such as the sealing surface between the valve body and the valve cover) to prevent the leakage of the medium from the joint surface.

Gaskets can also be divided into soft and hard two kinds. Soft materials are generally non-metallic, such as cardboard, rubber, asbestos-free rubber sheet, polytetrafluoroethylene, etc. Hard is generally metal or metal coated graphite, metal and graphite wound gasket. Metal gaskets are generally made of high-quality carbon steel and stainless steel, with high processing accuracy and surface roughness requirements, and the strength of fastening bolts is also large, which are used for high temperature and high pressure valves. The requirements for the gasket material of the valve are corrosion resistance, and at the same time, it has certain elasticity and plasticity at the working temperature and sufficient strength to ensure the sealing. The reasonable choice of gasket material and type should be determined according to the working conditions of the medium, such as temperature, pressure and corrosion.
