Description

A kind of knife gate valve of wear-resisting high leakproofness
Technical field
The utility model relates to control valve technical fields, and in particular to a kind of knife gate valve of wear-resisting high leakproofness.
Background technique
Gate valve is one of most common block valve, is mainly used to connect or be truncated the medium in pipeline, does not apply to adjust Rate-of flow.The pressure of utilization, temperature and diameter range are very big, especially apply in, the pipeline of major diameter.At present gate valve Sealing is compressed to be unilateral in many cases, no secondary seal operation, leakproofness cannot be protected, so that generating leakage feelings Condition.
Utility model content
The purpose of the utility model is to provide a kind of compact-sized, the knife gate valves of the high wear-resisting high leakproofness of leakproofness.
Purpose of the utility model is realized as follows: a kind of knife gate valve of wear-resisting high leakproofness, including valve deck, valve Body;
The valve deck includes handwheel, valve rod, bracket;The handwheel is connect with valve rod, and the valve rod is turned by valve stem nut It is dynamic to rise;
The valve body includes knife type valve plate, limited block, screw, valve seat from top to bottom;The valve body and valve deck pass through bolt Connection, the valve body is interior to be equipped with the runner flowed for fluid, and the limited block of fixed knife gate valve, the knife are equipped in the runner Type valve plate is fixedly connected with valve rod, and the knife type valve plate cutting edge of a knife or a sword mouth end is equipped with wear-resisting fixed block.
Compared with prior art, the utility model have the beneficial effect that due in runner be provided with limited block, make valve The direction of motion of plate is protected;Due to being provided with the screw of secondary fastening in runner side, the sealing of valve plate is even closer;By It will not wear, prolong the service life easily so that runner is more wear-resisting in being provided with anti-wearing liner on the inside of runner.
As a preferred embodiment of the present invention: the runner side is provided with the screw of secondary fastening.
Further preferred scheme as the utility model: anti-wearing liner is provided in the runner.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 valve deck, 2 valve bodies, 3 handwheels, 4 valve rods, 5 brackets, 6 knife type valve plates, 7 limited blocks, 8 screws, 9 valve seats, 10 spiral shells Bolt, 11 wear-resisting fixed blocks, 12 anti-wearing liners, 13 valve stem nuts.
Specific embodiment
As shown in Figure 1, a kind of knife gate valve of wear-resisting high leakproofness, including valve deck 1, valve body 2;
Valve deck 1 includes handwheel 3, valve rod 4, bracket 5;Handwheel 3 is connect with valve rod 4, and valve rod 4 passes through in the rotation of valve stem nut 13 It rises;
Valve body 2 includes knife type valve plate 6, limited block 7, screw 8, valve seat 9 from top to bottom;Valve body 2 and valve deck 1 pass through bolt 10 Connection is equipped with runner flow for fluid in valve body 2, is equipped with the limited block 7 of fixed blade type flashboard 6 in runner, knife type valve plate 6 and Valve rod 4 is fixedly connected, and 6 cutting edge of a knife or a sword mouth end of knife type valve plate is equipped with wear-resisting fixed block 11.
Above-mentioned runner side is equipped with the screw 8 of secondary fastening,
Anti-wearing liner 12 is provided in above-mentioned runner.
The working principle of the utility model is described below: handwheel 3 rotates, and valve stem nut 13 declines with ovable valve stem 4, blade type valve 6 stress of plate is pressed down against wear-resisting fixed block 11, and Gate-valve sealing carries out secondary compression to knife type valve plate 6 again by screw 8, with Improve the leakproofness of gate valve.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this For the technical staff in field according to disclosed technology contents, not needing creative labor can be special to some of which technology Sign makes some replacements and deformation, these replacements and deformation are within the protection scope of the present utility model.
