Description
Technical field
The utility model relates to mechanical field, particularly relates to a kind of high-pressure ball valve.
Background technique
At present, " O " RunddichtringO of using of partial high pressure ball valve causes sealability to decline the leakage caused to its corrosion injury or elastic failure etc. because of Environmental Conditions and raw material; Long-time frequent keying causes valve rod to damage.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of high-pressure ball valve of new structure, make it have more value in industry.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of high-pressure ball valve of Leakage prevention.
High-pressure ball valve of the present utility model, comprise: valve body, spheroid, valve rod, valve body is provided with outlet passage, inlet channel and spherical installation cavity, sphere installation is in spherical installation cavity, the fitting surface of spherical installation cavity and spheroid is provided with annular caulking groove, hard graphite grooved metal gasket is installed in caulking groove, valve stem seal cavity and valve body split, sealed by hard between ball seal chamber and spheroid, wherein a hard sealing is provided with spring with valve body place.
Further, also comprise valve gap, wherein valve gap is positioned on the valve rod that is exposed at outside spheroid.
By such scheme, the utility model at least has the following advantages:
The utility model efficiently solves " O " RunddichtringO that partial high pressure ball valve uses because of Environmental Conditions and raw material and causes sealability to decline the leakage caused to its corrosion injury or elastic failure etc.; Valve stem seal cavity and valve body split, and valve rod and seal chamber lengthen, and the sealability adding valve rod place solves because long-time frequent keying causes valve rod to damage simultaneously and changes the simplicity of valve rod; Ball seal chamber and spheroid change hard into and seal, and wherein the sealing of hard is provided with spring with valve body place, and the sealing that both improve because of spheroid displacement also reduces the unlatching moment of torsion of high-pressure ball valve.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model high-pressure ball valve.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Shown in Figure 1, a kind of high-pressure ball valve, comprise: valve body 1, valve gap 2, spheroid 3, valve rod 4, described valve body 1 is provided with outlet passage 5, inlet channel 6 and spherical installation cavity 7, spheroid 3 is installed in spherical installation cavity 7, the fitting surface of spherical installation cavity and spheroid is provided with annular caulking groove, hard graphite grooved metal gasket 8 is installed in caulking groove, make it to closely cooperate, efficiently solving " O " RunddichtringO that partial high pressure ball valve uses because of Environmental Conditions and raw material causes sealability to decline the leakage caused to its corrosion injury or elastic failure etc.; Valve rod 4 seal chamber and valve body split, and valve rod and seal chamber lengthen, and the sealability adding valve rod place solves because long-time frequent keying causes valve rod to damage simultaneously and changes the simplicity of valve rod; Ball seal chamber and spheroid change hard into and seal, and wherein the sealing of hard is provided with spring with valve body place, and the sealing that both improve because of spheroid displacement also reduces the unlatching moment of torsion of high-pressure ball valve.
The utility model efficiently solves " O " RunddichtringO that partial high pressure ball valve uses because of Environmental Conditions and raw material and causes sealability to decline the leakage caused to its corrosion injury or elastic failure etc.; Valve stem seal cavity and valve body split, and valve rod and seal chamber lengthen, and the sealability adding valve rod place solves because long-time frequent keying causes valve rod to damage simultaneously and changes the simplicity of valve rod; Ball seal chamber and spheroid change hard into and seal, and wherein the sealing of hard is provided with spring with valve body place, and the sealing that both improve because of spheroid displacement also reduces the unlatching moment of torsion of high-pressure ball valve.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
