Description
Technical field
This utility model is related to a kind of stop valve.
Background technology
Stop valve, is also pipe valve, is a kind of one of most popular valve, why very popular it is, is due to opening
During closing, between sealing surface, frictional force is little, relatively durable, and Lift is less, easy to manufacture, easy to maintenance, is applicable not only to
Mesolow, and it is applied to high pressure.The closure principle of stop valve is to rely on valve stem pressure, make valve clack sealing surface and valve base sealing
Face fits tightly, and stops flow of media.
Existing stop valve when closed, directly blocks the liquid flowing in pipeline, leads in the pipeline of stop valve one end
Pressure is increased dramatically, and the pressure in stop valve other end pipeline strongly reduces, thus leading to pipeline to produce high vibration, easily leads
Cause Pipeline damage.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of stop valve.
The purpose of this utility model is achieved through the following technical solutions:
A kind of stop valve, including valve body, main gate-board, main control bar, auxiliary gate-board and sub-control bar；
Described valve body possesses cavity, the wall of described cavity offers main gate-board accommodating chamber, described main gate-board is slidably
It is arranged at described main gate-board and accommodates intracavity, described main control bar runs through the wall of described cavity and described main gate-board rotationally connects
Connect, described main control bar is threadeded with the wall of described cavity；
The cushion hole of insertion in the direction of the width is offered on described main gate-board, the wall of described cushion hole offers secondary lock
Plate receiving hole, described auxiliary gate-board is arranged at described auxiliary gate-board and accommodates in the hole；Offer along its axis direction in described main control bar
Extend through the control hole at the two ends on its axis direction, described control hole is connected with described auxiliary gate-board receiving hole, described pair
Control bar is run through described control hole and is coordinated with described control hole screw thread, and described sub-control bar and described auxiliary gate-board rotationally connect
Connect.
The stop valve that this utility model provides, it rotates main control bar first when using, and main control bar drives main gate-board
Move downward and cavity is divided into two parts.Now due to offering cushion hole on main gate-board, partially liq can continue to lead to
Cross cushion hole and flow to another part so that the pressure stop valve one end declines by a small margin so that ending from a part for cavity
Pressure in valve one end rises by a small margin, significantly alleviates the vibration of pipeline.Then rotate sub-control bar, sub-control bar drives secondary
Flashboard moves downward, so that auxiliary gate-board closing cushion hole.Now the liquid flowing in pipeline is blocked completely.This practicality is new
The stop valve that type provides adopts two steps to block the flowing of the liquid in pipeline completely, thus avoid once directly blocking in pipeline
The liquid pipeline pressure that leads to of flowing drastically change, the vibration of pipeline can be alleviated, improve pipeline life.
Further, also include the main control handle being connected with described main control bar outer peripheral face；
Also include the sub-control handle being connected with described sub-control bar outer peripheral face.
Setting main control handle and sub-control handle are so that the control to main gate-board and auxiliary gate-board is easier.
Further, also include with the cooperation of described sub-control bar screw thread and with the upper surface of described main control bar against lock
Jack panel.
When controlling main control bar to rotate, sub-control bar may be produced relative rotation with main control bar, leads to control difficulty.
For this reason, setting locking nut.Locking nut is resisted against the upper surface of main control bar, thus avoiding sub-control bar to produce with main control bar
Life relatively rotates.
Further, also include the primary seal bar being arranged on the inwall of described main gate-board accommodating chamber.
Setting primary seal bar, improves sealing property, it is to avoid the liquid in pipeline is revealed by main gate-board accommodating chamber.
Further, also include the auxiliary sealing strip being arranged on the inwall of described auxiliary gate-board receiving hole.
Setting auxiliary sealing strip, improves sealing property, it is to avoid the liquid in pipeline is revealed by auxiliary gate-board receiving hole.
In sum, advantage of the present utility model and having the beneficial effects that:
1. the stop valve that this utility model provides adopts two steps to block the flowing of the liquid in pipeline completely, thus avoiding
The pipeline pressure that once directly the liquid flowing in blocking-up pipeline leads to drastically changes, and can alleviate the vibration of pipeline, improve pipe
The road life-span.
2. setting main control handle and sub-control handle are so that the control to main gate-board and auxiliary gate-board is easier.
3. when controlling main control bar to rotate, sub-control bar may be produced relative rotation with main control bar, lead to control and be stranded
Difficult.For this reason, setting locking nut.Locking nut is resisted against the upper surface of main control bar, thus avoiding sub-control bar and main control
Bar produces relative rotation.
4. primary seal bar is set, improves sealing property, it is to avoid the liquid in pipeline is revealed by main gate-board accommodating chamber.
5. auxiliary sealing strip is set, improves sealing property, it is to avoid the liquid in pipeline is revealed by auxiliary gate-board receiving hole.
