Abstract

The invention discloses a ball valve regulating device. The ball valve regulating device comprises a valve body and a valve seat; the valve body is mounted in the valve seat; a spring seat is arranged outside the valve seat; a compression spring of which the tightness can be controlled by use of an adjusting bolt is arranged between the spring seat and the valve seat; the tail end of the spring seat is mounted in a sliding chute seat and the spring seat is capable of moving in the sliding chute seat under the control of the adjusting bolt. According to the ball valve regulating device, the compression spring is held down in the spring seat and the valve seat is put into the valve body; as the compression spring is compressed before the mounting of a ball, the ball can be mounted very conveniently; after the ball is assembled, the adjusting bolt is untightened and withdrawn from the spring seat, and at the moment, the pre-tightening force on the ball exerted by the compression spring is relatively small; when the pre-tightening force needs to the increased, the adjusting bolt is used for adjustment; as a result, convenient assembly of the ball valve and adjustable pre-tightening force are realized.

Description

A kind of ball valve controlling device
Technical field
The present invention relates to a kind of controlling device, relate to a kind of ball valve controlling device specifically.
Background technique
Upper-mounting type ball valve is widely used on oil and natural gas pipeline, and recover the oil, oil refining, petrochemical industry, chemical industry, chemical fibre, metallurgical, electric power, nuclear power, in the device such as food and papermaking, upper-mounting type ball valve is dismantled rapidly simple on pipeline, fast easy to maintenance, when valve break down on pipeline need repair time, valve need not be dismantled from pipeline, need only to dismantle flange bolt and nut, valve gap is taken off together with valve rod group component from valve body, then spheroid and valve seat combination part is taken out, spheroid and valve seat can be repaired online, such maintenance saves the time, but there are some shortcomings in existing ball valve controlling device: initial tension of spring can not adjust and control, and amount of spring compression is large during assembling, assembling difficulty.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose and a kind ofly assemble easy, that pretightening force is adjustable ball valve controlling device.
Technical solution of the present invention is achieved in that a kind of ball valve controlling device, comprises valve body, valve seat; Described valve body is arranged in valve seat; Described valve seat outside is provided with spring seat; The Compress Spring being controlled degree of tightness by adjusting bolt is provided with between described spring seat and valve seat; Described spring seat tail end is arranged in sliding chute seat, and spring seat can move under adjusting bolt controls in sliding chute seat.
Preferably, seal ring is provided with between described valve seat and valve body.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of ball valve controlling device of the present invention, by being provided with spring seat in valve seat outside, the Compress Spring being controlled degree of tightness by adjusting bolt is provided with between spring seat and valve seat, spring seat tail end is arranged in sliding chute seat, spring seat can move under adjusting bolt controls in sliding chute seat, Compress Spring is pressed in spring seat, valve seat is loaded valve body, because before installation spheroid, Compress Spring is compressed, so it is very convenient to install spheroid, when after spheroid assembling, adjusting bolt is unscrewed, exit spring seat, now Compress Spring is less for the pretightening force of spheroid, when needs increase pretightening force, available adjustment bolt adjusts, so just achieve the convenience of ball valve assembling, pretightening force adjustable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of ball valve controlling device of the present invention;
Wherein: 1, valve body; 2, valve seat; 3, spring seat; 4, Compress Spring; 5, adjusting bolt; 6, sliding chute seat; 7, seal ring.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is a kind of ball valve controlling device of the present invention, comprises valve body 1, valve seat 2; Described valve body 1 is arranged in valve seat 2; Described valve seat 2 outside is provided with spring seat 3; The Compress Spring 4 being controlled degree of tightness by adjusting bolt 5 is provided with between described spring seat 3 and valve seat 2; Described spring seat 3 tail end is arranged in sliding chute seat 6, and spring seat 3 can move under adjusting bolt 5 controls in sliding chute seat 6; Seal ring 7 is provided with between described valve seat 2 and valve body 1.
A kind of ball valve controlling device of the present invention program, by being provided with spring seat 3 in valve seat 2 outside, the Compress Spring 4 being controlled degree of tightness by adjusting bolt 5 is provided with between spring seat 3 and valve seat 2, spring seat 3 tail end is arranged in sliding chute seat 6, spring seat 3 can move under adjusting bolt 5 controls in sliding chute seat 6, Compress Spring 4 is pressed in spring seat 3, valve seat 2 is loaded valve body 1, because before installation spheroid, Compress Spring 4 is compressed, so it is very convenient to install spheroid, when after spheroid assembling, adjusting bolt 5 is unscrewed, exit spring seat 3, now Compress Spring 4 is less for the pretightening force of spheroid, when needs increase pretightening force, available adjustment bolt 5 adjusts, so just achieve the convenience of ball valve assembling, pretightening force adjustable.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.

Claims (2)

1. a ball valve controlling device, is characterized in that: comprise valve body, valve seat; Described valve body is arranged in valve seat; Described valve seat outside is provided with spring seat; The Compress Spring being controlled degree of tightness by adjusting bolt is provided with between described spring seat and valve seat; Described spring seat tail end is arranged in sliding chute seat, and spring seat can move under adjusting bolt controls in sliding chute seat.
2. a kind of ball valve controlling device as claimed in claim 1, is characterized in that: be provided with seal ring between described valve seat and valve body.
