To control the unlatching of self contained block valve, during self contained block valve maintains open state, can also automatically adjust
Controllable type check valve imports and exports the pressure difference at both ends, prevents self contained block valve because closing caused by hypotony.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the high pressure check valve that a kind of band provided by the utility model enforces handle.
Fig. 2 is the schematic diagram being applied to check valve provided by the utility model on block valve.
Specific embodiment
The preferred embodiment of the utility model is illustrated below according to Fig. 1 and Fig. 2.
As shown in Figure 1, the utility model provides a kind of high pressure check valve of band compulsory execution handle, include:
Valve body 8, with inlet end and an outlet end；
Bonnet 3 is threadedly coupled with valve body 8；
Valve rod 7 passes through bonnet 3 and is arranged in the inner cavity of valve body 8；
Valve ball 12 is arranged in the input end cavity of valve body 8；
Mandril 10 is arranged in the inner cavity of valve body 8, and one end is connect with valve rod 7, and the other end can contact valve ball 12；
Handle 1 is located at outside valve body 8, connect with the other end of valve rod 7.
Further, it is additionally provided with valve ball retaining ring 13 on the high pressure check valve, the input end of valve body 8 is set, used
In preventing valve ball 12 from falling off.Plain cushion 4 is additionally provided between valve body 8 and bonnet 3.Locking nut 2 is additionally provided on valve rod 7,
It is located at 1 lower part of handle, for preventing handle 1 to be subjected to displacement.
In order to realize preferably sealing effect, valve ball sealing ring is set on the contact surface of valve ball 12 and input end cavity
11, and seal ring assembly is set on the contact surface of valve rod 7 and valve body 8, which contains at least two sealing ring,
In the present embodiment, which includes: the first sealing ring 5, the second sealing ring 6 and third sealing ring 7.
The working principle for the high pressure check valve that a kind of band provided by the utility model enforces handle is as follows:
When high pressure check valve input end has pressure, and outlet end does not have pressure, valve ball 12 is withstood on valve by import end pressure
Sealing is formed on ball sealing ring 11, fluid can not enter control loop after valve by high pressure check valve, and import end pressure is bigger, close
It is better to seal effect；
Driving handle 1, handle 1 are moved down with ovable valve stem 7, and valve rod 7 pushes mandril 10 to open valve ball 12, and fluid is from import
End flows to outlet end, and high pressure check valve is forced open at this time；
When inlet end and an outlet end pressure keeps balancing, because valve ball 12 is pushed without spring, valve ball 12 is in free shape
State, import end pressure can add to outlet end at any time, to maintain the pressure balance of inlet and outlet；
When outlet pressures quick pressure releasing, 12 moment of valve ball contacts formation sealing, cut-out pressure with valve ball sealing ring 11
Supply loop.
As shown in Fig. 2, band provided by the utility model is enforced handle in one embodiment of the utility model
High pressure check valve be applied on block valve, open the first needle-valve A1, production flow line fluid enters control pipeline, and band is forced at this time
The high pressure check valve D for executing handle is in close state, and fluid cannot be introduced into the toucher import of block valve SSV, block valve SSV
It is in close state；The compulsory execution handle of check valve D is pushed, the mandril of check valve D opens valve ball, and fluid passes through check valve D
Into the toucher import of block valve SSV, block valve SSV is opened, and production flow line is connected；When control pipeline Fluid pressure is higher than height
Pressure sensor C or setting value lower than low pressure sensor B, high pressure sensor C or low pressure sensor B release quickly control pressure,
Sealing is generated between the valve ball of check valve D and valve ball sealing ring at this time, check valve D is closed, and the fluid before preventing check valve enters
Pipeline is controlled, block valve SSV is closed, production flow line cutting；When block valve SSV is in Normal on state, the both ends check valve D
Pressure balance, valve ball are in free state, at this point, the pressure of production flow line can be transmitted to the control pipe after check valve D at any time
Line, to maintain the pressure of control pipeline.
Check valve is reversely installed, need to be by forcing handle to open check valve when block valve is opened, and fluid is from controllable type list
Enter block valve toucher control mouth to valve, opens block valve；It decontrols check valve and forces handle, block valve, which enters, continues opening state
State；Under emergency case, block valve is closed in the control valve pressure release of block valve control section, and check valve is automatically closed at this time, cutting control
Circuit processed, solving check valve simple function is inconvenient to the problems such as operating.
Check valve provided by the utility model not only has the function of conventional one-way valve, moreover it is possible to valve ball unlatching is manually controlled,
To control the unlatching of self contained block valve, during self contained block valve maintains open state, can also automatically adjust
Controllable type check valve imports and exports the pressure difference at both ends, prevents self contained block valve because closing caused by hypotony.
It is discussed in detail although the content of the utility model has passed through above preferred embodiment, but it should be appreciated that on
The description stated is not considered as limitations of the present invention.After those skilled in the art have read above content, for
A variety of modifications and substitutions of the utility model all will be apparent.Therefore, the protection scope of the utility model should be by appended
Claim limit.
