The structural features of the knife gate valve
1.can lift the seal face of the gate, can scrape the adhesive on the seal surface, and automatically remove the sundries.
2.stainless steel gate can prevent the seal leakage caused by corrosion.
3.the whole stainless steel material, can prevent corrosion damage.
4.short structure length can save the material, install space, and support the strength of the pipe.
5.scientific sealing packing design is designed to make the upper seal safe and effective and durable.
6. triangular yoke save the raw materials to ensure the mechanical properties required.
7.valve body makes the gate move correctly. The extrusion block ensures the effective seal of the gate.
8.valve stiffener is designed to improve the strength of the valve body.
9.stainless steel valve stem is durable and double head snails are used more quickly.
10.the driving mechanism can be chosen arbitrarily.
11 .V type gate can be used as a regulating valve.
Installation and use
1.before installation, check whether the type of valve is in conformity with the working condition.
2. rubber,tetrafluoro and other soft seals, must check the valve inner cavity and sealing surface and other parts of the parts, such as the need to clean.
3 .users must consider the necessary space for retaining the valve drive before installation.
4. the factory (electrohydraulic) valve has been debugged at the factory. When users use each time, in order to prevent wiring errors,the valve is opened to the half open state manually then the power is connected to the power supply to carry out no load trial.The gas source of.
5.gas(liquid) valve must be guaranteed to supply sufficient gas(liquid) pressure.The bolt should be tightened evenly when the.
6.is installed.
7.the valve can not be strongly impacted or unscrewed the valve parts at any time.
8.the sealing place on the valve is exposed regularly,and the seal should be added to the seal regularly.
9.in the dry area,when the valve drive is a positive gear,the lubricating oil must be added regularly.
