The opening and closing parts of the high temperature resistant gate valve are the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and closed, and cannot be adjusted or throttled.The gate has two sealing surfaces. The two sealing surfaces of the Z common mode gate valve form a wedge, and the wedge angle varies with the valve parameters.
The fluid resistance is small, and the sealing surface is less scoured and eroded by the medium.
It is easier to open and close.
The flow direction of the medium is not restricted, the flow is not disturbed, and the pressure is not reduced.
Simple shape, short structure length, good manufacturing process and wide application range.
High temperature resistant gate valveInstallation, maintenance and precautions:
Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
The double ram gate valve shall be installed vertically (that is, the valve stem is in a vertical position and the hand wheel is at the top).
The gate valve with bypass valve shall be opened before opening (to balance the pressure difference between inlet and outlet and reduce the opening force).
The gate valve with transmission mechanism shall be installed according to the product manual.
If the valve is used frequently, lubricate it at least once a month.
characteristic:
Light weight: the body is made of high-grade nodular black cast iron, which is about 20%~30% lighter than the weight of traditional gate valves, and easy to install and maintain.
Flat bottom gate seat: the traditional gate valve is often silted in the bottom groove of the valve due to foreign objects such as stones, wood blocks, cement, iron filings, sundries, etc. after the pipe is washed with water, which is easy to cause the phenomenon of water leakage because it cannot be closed tightly. The bottom of the elastic seat sealed gate valve is designed with the same flat bottom as the water pipe machine, which is not easy to cause the accumulation of sundries, making the fluid unobstructed.
Overall rubber coating: high-quality rubber is used for the internal and external rubber coating of the ram. The rubber vulcanization technology of Europe * enables the vulcanized ram to ensure accurate geometric dimensions, and the rubber is firmly connected with the ductile cast ram, which is not easy to fall off and has good elastic memory.water
Precision casting valve body: the valve body is precision cast, and the precise geometric dimensions make it possible to ensure the sealing of the valve without any finishing inside the valve body.
