Description
Technical field
The utility model is related to a kind of valve, specifically a kind of blass stop valve.
Background technology
Blass stop valve is since with anticorrosive, long-lived effect is welcome always, but since blass stop valve material is asked at present
Topic, is generally used for small-sized gate valve, when mostly using in family's pipeline engineering, but being opened in use due to blass stop valve, people
Often valve is screwed to the flashboard of blass stop valve is finally caused to deviate, under water hammering and cause valve to shake under water impact
It is dynamic, the sound is sent out, and cause flashboard to shake after the first Secondary Shocks, the sealing with valve body loosens, and sealing effect declines and sounding
Troublesome frequencies increase, and cause to perplex to the life of the people.
Utility model content
The purpose of this utility model is to provide a kind of blass stop valve.
To achieve the above object, the technical solution of the utility model includes valve body, and valve body left end is equipped with water inlet, and right end is set
There is water outlet, flashboard is equipped on the inside of valve body, valve rod is equipped on the upside of flashboard, valve deck is equipped on the upside of valve body, is set between valve deck and valve body
There is gasket, anti-return nut is equipped on the downside of valve deck, locking nut is equipped on the upside of valve deck, limited block, limit are equipped on the upside of locking nut
Block is connect by fixing bolt with locking nut, and the torque spring being socketed on fixing bolt, valve rod top are equipped in limited block
Equipped with limiting slot, valve rod is equipped with sealing ring with valve deck contact side, and valve stem top is equipped with the handwheel connected by fixing nut, limit
Block is corresponded to close to valve rod, and in limiting slot.
Due to the adoption of the above technical scheme, the beneficial effects of the utility model：
1, flashboard excessive deflection is limited by the cooperation of limited block and limiting slot, is impacted by water hammer effect flow, prevented
Only valve shakes sounding, extends valve service life.
2, coordinate the offset for realizing limited block by torque spring, facilitate the dismounting of valve rod, be conducive to maintaining.
Description of the drawings
The utility model is described further in conjunction with attached drawing.

Specific implementation mode
As shown in Figs. 1-2, the utility model includes valve body 1, and 1 left end of valve body is equipped with water inlet 2, and right end is equipped with water outlet
16,1 inside of valve body is equipped with flashboard 3, and 3 upside of flashboard is equipped with valve rod 4, and 1 upside of valve body is equipped with valve deck 5, between valve deck 5 and valve body 1
Equipped with gasket 6,5 downside of valve deck is equipped with anti-return nut 7, and 5 upside of valve deck is equipped with locking nut 8, and 8 upside of locking nut is equipped with limit
Block 9, limited block 9 are connect by fixing bolt 10 with locking nut 8, and the torsion being socketed on fixing bolt 10 is equipped in limited block 9
Power spring 11,4 top of valve rod are equipped with limiting slot 12, and valve rod 4 contacts side with valve deck 5 and is equipped with sealing ring 13, and 4 top of valve rod is equipped with logical
The handwheel 15 of the connection of fixing nut 14 is crossed, limited block 9 is corresponded to close to valve rod 4, and in limiting slot 12.
The operation principle of the utility model：The technical program realizes limitation lock by the cooperation of limited block 9 and limiting slot 12
3 opening angle of plate, prevent from excessively opening is influenced impact endurance test shock by water hammer effect, is influenced service life and is sent out the sound, is led to simultaneously
The offset that torque spring 11 realizes limited block 9 is crossed, facilitates the dismounting of valve rod 4, utilizes maintaining.
