Description

A kind of high-pressure stop valve
Technical field
The utility model is a kind of high-pressure stop valve, belongs to hardware engineering device technique field.
Background technology
Shut-off valve is also known as pipe valve valve, belongs to forced seal formula valve, so when valve is closed, it is necessary to apply to flap and press Power is not leaked with forced seal face.When medium below flap by entering valve, the resistance overcome required for operating force, is valve The frictional force of bar and filler and thrust caused by the pressure by medium, the power of closing valve is bigger than the power of valve opening door, so valve rod Diameter it is big, the failure of valve rod bending otherwise can occur.It is divided into three kinds by connection type:Flanged joint, screwed connection, welding Connection.After the appearance of the valve of self sealss, the medium flow direction of shut-off valve just changes by entering valve chamber above flap, at this moment in medium pressure Under force effect, the power of closing valve is small, and the power of valve opening door is big, and the diameter of valve rod can be reduced correspondingly.Meanwhile it being acted in medium Under, the valve of this form is also relatively tight.China's valve " three change give " once provides, the flow direction of shut-off valve, without exception using from upper and Under.When shut-off valve is opened, the Lift of flap, flows have reached maximum when being the 25%~30% of nominal diameter, indicate valve Door has reached fully open position.So the fully open position of shut-off valve, should be determined, but existing shut-off valve is being used by the stroke of flap When, when closing, since internal pressure is larger, and internal seal is bad, leads to often have the case where leak.

Further, using interference fit between the plunger and sealing ring.
Further, the material that the sealing ring uses is strong for resilience, and the nontoxic novel seal that wasting property is high.
Further, the conical surface seal position of the valve seat and plunger, the material used is the high-quality resistance to material wasted.
Further, the connection type between the valve deck and bolt is rotation connection.
A kind of high-pressure stop valve of the utility model, has the beneficial effect that:
A kind of high-pressure stop valve of the utility model, the device are equipped with sealing ring, by adjusting valve deck fixing bolt It compresses, sealing ring is made to be compressed, valve chamber inner wall is close in inner ring hard-pressed bale plunger outer ring, the generated radial direction point in this way on sealing ring Power will be the pressure of fluid, to ensure that leakproofness, prevent external leakage, functional complete, multi-purpose content is saved empty Between.
Description of the drawings
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other spies of the utility model Sign, objects and advantages will become more apparent upon:
Fig. 1 is a kind of positive structural schematic diagram of high-pressure stop valve of the utility model.
In figure:Device body -1, valve body -2, valve seat -3, sealing ring -4, valve rod -5, handwheel -6, valve rod side protection -7, Valve deck -8, plunger -9, bolt -10, valve chamber -11, water outlet -12.
Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below In conjunction with specific implementation mode, the utility model is expanded on further.
Referring to Fig. 1, the utility model provides a kind of high-pressure stop valve:Its structure includes device body 1, valve body 2, valve seat 3, sealing ring 4, valve rod 5, handwheel 6, valve rod side protection 7, valve deck 8, plunger 9, bolt 10, valve chamber 11 and water outlet 12, it is described The top of device body 1 is equipped with handwheel 6, and the bottom of the handwheel 6 is connect with valve rod 5, the company between the handwheel 6 and valve rod 5 It is rotation connection to connect mode, and the both sides of the valve rod 5 are equipped with valve rod side and protect 7, and the valve rod side protection 7 is located at valve body 2 Top, the both sides of valve rod side protection 7 are equipped with valve deck 8, and the bottom of the valve deck 8 is equipped with bolt 10, the valve rod 5 Bottom is connect with plunger 9, and the connection type between the plunger 9 and valve rod 5 is to be fixedly connected, and the bottom of the plunger 9 is equipped with Valve seat 3, the valve seat 3 are located at the middle part of device body 1, and the both sides of the valve seat 3 are equipped with valve chamber 11, the bottom of the valve seat 3 With bottom right side and equipped with water outlet 12.
As a kind of preferred technical solution in the present embodiment, using interference fit, energy between the plunger 9 and sealing ring 4 Enough protective device ontologies 1 will not be damaged because internal pressure is excessive.
