Description

A kind of super-pressure check valve easy to use
Technical field
The present invention relates to check valve field, and in particular to a kind of super-pressure check valve easy to use.
Background technology
Existing check valve due to be machining metal to metal sealing surface because the difference of the accuracy of manufacture, In the presence of spring force, substantially it cannot be guaranteed that its sealing property, generally requires to obtain good patch using other supplementary means Close sealing surface;Once after the reliable sealing of valve seat and valve head formation No leakage, if not limiting circumferentially rotating for spherical valve head, In the state of valve is opened, spherical to be rotated because of the inhomogeneities of fluid stress, the sealing position of laminating occurs originally Relative angular displacement, causing to again appear in the presence of spring force can not sealed state.
The content of the invention
The technical problems to be solved by the invention are that spherical easy inhomogeneities rotates in the state of valve opening, Originally relative angular displacement occurs for the sealing position of laminating, can reduce the sealing of check valve, it is therefore intended that provide what is be easy to use A kind of super-pressure check valve, the problem of solving the sealing of check valve.
The present invention is achieved through the following technical solutions:
A kind of super-pressure check valve easy to use, including joint, valve seat, spherical valve head, spring, valve body, the valve seat It is connected in joint, the other end of valve seat is connected with spherical valve head, the other end of the spherical valve head is connected with spring, the ball Shape valve head and spring are both connected in valve body, and the outside of joint is connected with valve body, and the inside of the valve seat is logical for cylinder Hole, and valve seat has close to one end of spherical valve head and is connected with ball on some grooves, one end of the nearly valve seat of globe valve head rest Shape connector, and some projections are connected with by spherical connector, the projection is corresponding with groove to be connected, the spherical connection There are some passways on head.
Further, present apparatus valve seat is sealed in the presence of joint with valve body formation, it is ensured that fluid will not be to product External leakage, when positive import is with reversely exporting no pressure difference or pressure differential less than Opening pressure, spherical valve head relies on spring force Sealed, when reverse outlet has pressure differential with positive import, sealed by spring and pressure difference, and then ensure reverse Close.
Specifically, the afterbody of spherical valve head is cylinder, cylinder can guarantee that slip and guiding on axial direction, can Effective to slide, the taper surface formation sealing pair of spherical connector and valve seat further realizes sealing, and by projection with it is recessed The connection of groove, constrains the free degree of spherical valve head in the axial direction, and then prevent valve seat from forming the reliable close of No leakage with valve head Be honored as a queen, do not limiting circumferentially rotating for spherical valve head, and in the state of valve opening, it is spherical can because fluid stress not Uniformity rotates, and relative angular displacement occurs for the sealing position of laminating originally, causes to again appear in the presence of spring force Can not be sealedly the occurrence of.Therefore the present apparatus can further reach sealed effect, particularly the state in super-pressure Under can also reach preferable sealing effectiveness.
It is preferred that, a kind of super-pressure check valve easy to use, the valve seat is with being taper surface at valve body contact.Taper surface Sealed effect can be preferably reached, is more convenient for using.
It is preferred that, a kind of super-pressure check valve easy to use, the groove is identical with number of projection and described recessed The number of groove is at least four, and groove is evenly distributed in around cylindrical hole.Such structure can be evenly more steady Solid fixed valve base and spherical valve head, fixation it is more firm.
Further, a kind of super-pressure check valve easy to use, the valve seat and spherical valve head are metal material.Entirely The encapsulant of metal, can guarantee that the high temperature resistant and high voltage bearing characteristic of product, and then the use scope of the present apparatus is wider, uses It is more convenient.
It is preferred that, a kind of super-pressure check valve easy to use is set with the spring due to placing spring in the valve body Groove, the width of the spring is identical with the width of spring groove.Can so it prevent spring from rocking, the situation hair for causing sealing to reduce It is raw.
The present invention compared with prior art, has the following advantages and advantages:
1st, a kind of present invention super-pressure check valve easy to use, by the connection of projection and groove, constrains globe valve The free degree of head in the axial direction, and then prevent valve seat with after the reliable sealing of valve head formation No leakage, not limiting spherical valve head Circumferentially rotate, it is spherical originally to be pasted because the inhomogeneities of fluid stress rotate and in the state of valve opening Relative angular displacement occurs for the sealing position of conjunction, causes to again appear at the occurrence of can not be sealedly in the presence of spring force;
2nd, the present invention a kind of super-pressure check valve easy to use, the present apparatus can effective high-temperature-resistant high-pressure-resistant, for superelevation The environment of pressure and high temperature can also have preferable sealing;
3rd, a kind of present invention super-pressure check valve easy to use, the present apparatus is simple in construction, is easy to use.
