Description

Gate valve

Technical Field

The utility model belongs to the technical field of the gate valve, especially, relate to a gate valve.

Background

The gate valve is an opening and closing flashboard, the motion direction of flashboard is perpendicular with the fluid direction, the gate valve only can be opened fully and closed fully, can not do regulation and throttle, the gate valve seals through disk seat and flashboard contact, usually sealed face can build-up welding metal material in order to increase the wearability, if build-up welding 1Cr13, STL6, stainless steel etc., the flashboard has rigidity flashboard and elasticity flashboard, according to the difference of flashboard, the gate valve divide into rigidity gate valve and elasticity gate valve, when the gate valve is closed, sealed face can only rely on medium pressure to seal, only rely on medium pressure to press the sealed face of flashboard to the disk seat of opposite side to guarantee sealed face sealed, this is exactly the self sealedly. Most gate valves are forcedly sealed, namely, when the valves are closed, the gate plates are forced to press the valve seats by external force so as to ensure the sealing performance of the sealing surfaces.

If the gate valve is rusted, rust-proof lubricant such as a valve rod and a valve rod needs to be added to relatively moving parts, a protective sleeve is additionally arranged to slow down the aging of lubricating grease, then the valve rod and the valve rod are coated with special coating (namely paint) in places without influencing operation, namely the valve rod is attractive and rustproof, and for steam medium or high-temperature and low-temperature gas medium valves, graphite sandwiched metal wire packing is adopted as far as possible, because graphite has excellent self-lubricating property and temperature alternation resistance, the problem that the valve rod is difficult to rotate due to the loss of the lubricating grease when the common packing is used for a long time is avoided.

In the industrial production process, the gate valve is generally arranged outdoors, and the gate valve is easy to corrode due to long-time use, so that the gate valve is difficult to open.

When the existing gate valve is used, the gate valve is difficult to adjust due to corrosion, and the use convenience of the gate valve is greatly reduced.

Therefore, the existing gate valve has the disadvantages of large rotation difficulty, poor use convenience and unsuitability for popularization and use.
