Abstract

The utility model discloses a plug valve for a water-eliminating hammer. The plug valve for the water-eliminating hammer is composed of a valve body, a valve cover, a plug, a valve rod and a bidirectional valve body, wherein the valve body is fixedly connected with the valve cover by a bolt; the plug is arranged in the valve body; a channel is formed in the plug, and a bidirectional valve is arranged in the channel; one end of the bidirectional valve is installed on a support disc on the inlet end of the channel, and the other end of the bidirectional valve is used for fixing the bidirectional valve body in the plug by a bolt. When the plug rotates 90 degrees, a medium flows in from a medium inlet, flows through a plug inlet, and pushes a valve core end cover, a return spring shrinks due to extrusion, thus the valve core end cover continues to be stressed to open a valve body through hole, the medium flows out from the valve body through hole and then flows in the channel, and the medium in the channel flows towards a medium outlet from a plug outlet; when the plug rotates 90 degrees again, the plug inlet is in a closed state, the medium flows back, and flows through a valve core through hole in the valve core end cover, a baffle is pushed by a backflow pressure, thus a valve core spring is returned to buffer the backflow pressure of the medium. The plug valve for the water-eliminating hammer disclosed by the utility model has the advantages of being good in waterproof hammer effect, capable of reducing noise, and long in service life.

Description

Water hammer stopcock disappears
Technical field
The utility model relates to stopcock, and water hammer stopcock is specifically related to disappear.
Background technique
In valve industry, water hammer often occurs, water hammer can cause superpressure or the negative pressure of current in pipeline, produces huge noise and damages element, in work and maintenance, brought very large loss and trouble.
Model utility content
The purpose of this utility model is to provide the one water hammer stopcock that disappears, and the utility model water hammer-resistant is effective, reduces noise, long service life.
The utility model adopts following technological scheme:
The water hammer stopcock that disappears, is comprised of valve body, valve gap, cock, valve rod and two-way valve valve body.
Described valve body and valve gap are bolted to connection, in valve body, there is a cock, in described cock, there is a passage, in passage, there is a two-way valve, two-way valve one end is placed on the supporting disk on channel entrance end, the other end is fixed on two-way valve valve body in cock by bolt, is mounted with a Returnning spring in two-way valve valve body, and Returnning spring is fixed by spool end cap and two-way valve valve body; Described valve core spring one end is fixed on spool by pad, and the other end and spool end cap are close to; Described spool one end is connected with block, and block and spool are integrated, and in the middle of block, has a cylinder shape groove, and spool end cap can embed in cylinder shape groove, between spool end cap and two-way valve valve body, has a seal washer.
On described spool end cap, have valve core through hole, on two-way valve valve body, have valve hole, between cock and two-way valve valve body, be provided with passage.
When cock 90-degree rotation, medium flows into from medium import, the cock entrance of flowing through, promote spool end cap, Returnning spring contractions that be squeezed, makes spool end cap continuation pressurized that valve hole is opened, medium is flow channel from valve hole flows out, and the medium in passage flows to media outlet from cock outlet.
When cock is again during 90-degree rotation, cock import is closed condition, medium back flow, and the valve core through hole of flowing through on spool end cap, return pressure promotes block, valve core spring is resetted, buffer medium return pressure.
Advantage of the present utility model: water hammer-resistant is effective, reduces noise, long service life.
Accompanying drawing explanation
Fig. 1 is complete section structural representation of the present utility model.
Wherein: 1. valve body, 2. valve gap, 3. valve rod, 4. cock, 5. bolt, 6. two-way valve valve body, 61. valve holes, 7. Returnning spring, 8. valve core spring, 9. pad, 10. spool, 11. spool end caps, 12. blocks, 13. seal washers, 14. valve core through hole, 15 passages, 131. medium imports, 132. media outlets.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the water hammer stopcock that disappears, is comprised of valve body 1, valve gap 2, valve rod 3, cock 4 and two-way valve valve body 6 the utility model.
Described valve body 1 is bolted to connection with valve gap 2, in valve body 1, there is a cock 4, in described cock 4, there is a passage, in passage, there is a two-way valve, two-way valve one end is placed on the supporting disk on channel entrance end, the other end is fixed on two-way valve valve body 6 in cock 4 by bolt 5, is mounted with a Returnning spring 7 in two-way valve valve body 6, and Returnning spring 7 is fixing with two-way valve valve body 6 by spool end cap 11; Described valve core spring 8 one end are fixed on spool 10 by pad 9, and the other end and spool end cap 11 are close to; Described spool 10 one end are connected with block 12, and block 12 is integrated with spool 10, in the middle of block 12, have a cylinder shape groove, and spool end cap 11 can embed in cylinder shape groove, has a seal washer 13 between spool end cap 11 and two-way valve valve body 6.
On described spool end cap 11, have valve core through hole 14, on two-way valve valve body 6, have valve hole 61, between cock 4 and two-way valve valve body 6, be provided with passage 15.
When cock 4 90-degree rotation, medium flows into from medium import 131, cock 4 entrances of flowing through, promote spool end cap 11, Returnning spring 7 contraction that is squeezed, make spool end cap 11 continue pressurized valve hole 61 is opened, medium is flow channel 15 from valve hole 15 flows out, and the medium in passage 15 flows to media outlet 132 from cock outlet.
When cock 4 is again during 90-degree rotation, cock 4 imports are closed condition, medium back flow, and the valve core through hole 14 of flowing through on spool end cap 11, return pressure promotes block 12, valve core spring 8 is resetted, buffer medium return pressure.
