Description
Technical field
The utility model relates to the structure of high-pressure ball valve, belongs to the valve in universal machine field.
Background technique
High-pressure ball valve is mainly used in high-pressure medium as high pressure water, hydraulic oil, chemical industry high-pressure medium etc., controls the open and close of this kind of medium system.Existing high-pressure ball valve mainly comprises valve body, valve gap, the first valve seat, the second valve seat, valve rod, handle, has the spheroid of intermediate throughholes, valve gap is connected with valve body, first valve seat, the second valve seat are arranged in valve body, spheroid is arranged between the first valve seat and the second valve seat, at the outer surface of spheroid, valve rod mounting groove is set, one end of valve rod is arranged in valve rod mounting groove, the other end is connected by nut with handle through after valve body, realizes opening and closedown of valve by handle rotating sphere 90-degree rotation.The high-pressure ball valve of this structure exist processing and assembling inconvenience, cost high, seal unreliable.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of processing and assembling forged steel 3 stops high-pressure ball valve easily.
The purpose of this utility model is achieved in that forged steel 3 stops high-pressure ball valve, comprise valve body, valve gap, the first valve seat, the second valve seat, valve rod, handle, there is the spheroid of intermediate throughholes, valve body connects locating stud, valve rod mounting groove is set at the outer surface of spheroid, one end of valve rod is fixed in valve rod mounting groove, the other end is connected by nut with handle through after valve body; Described valve gap comprises first valve gap with center hole and second valve gap with center hole, one end of valve body is threaded with the first valve gap, the other end is threaded with the second valve gap, spheroid is arranged between the first valve gap and the second valve gap, first valve seat is arranged between the first valve gap and spheroid, and the second valve seat is arranged between the second valve gap and spheroid.
Pressure-bearing shell of the present utility model forms pressure part by valve body, the first valve gap, the second valve gap, is applicable to high-pressure medium operating mode, facilitates forged steel materials microstructure and processing and assembling.Spheroid and the first valve seat, the second valve seat form Open-close sealing part, and spheroid is intermediate throughholes structure, fixing and rotatable 90 degree of valve inner.Spheroid top offers groove, and groove is connected with valve rod, drives spheroid synchronous rotary when valve rod rotates, and makes spheroid mesopore concentric with valve seat orifice or block and close respectively.Thus realize opening and closedown of valve passage.Valve body upper end portion is provided with locating stud, coordinates with handle, the limiter valve switching position, ensures that spheroid position of a rotary switch is accurate.The utility model compact structure, easy accessibility, cost is low.
As improvement of the present utility model, arrange the first seal ring between valve body and the first valve gap, arrange the second seal ring between valve body and the second valve gap, the first seal ring and the second seal ring can prevent high-pressure medium from leaking outside
As further improvement of the utility model, valve rod is wholely set boss near one end of spheroid, and between valve rod and valve body, arrange the 3rd seal ring and the 4th seal ring, the 3rd seal ring is arranged on the middle part of valve rod, and the 4th seal ring is arranged on the boss of valve rod.4th seal ring isolation valve rod and valve body make valve rod rotate steadily, eliminate dry friction, reduce running torque, play elementary seal action simultaneously; 3rd seal ring to be arranged in the middle part of valve body and valve rod cylindrical in annular groove, prevents high-pressure medium from leaking outside.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
