Abstract

The utility model relates to 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; The utility model scheme is by being pressed in spring seat by Compress Spring, 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 unscrewed, exit spring seat, now Compress Spring is less for the pretightening force of spheroid, when needs increase pretightening force, available adjustment bolt adjusts, and so just achieves the convenience of ball valve assembling, pretightening force adjustable.

Description

A kind of ball valve controlling device
Technical field
The utility model relates to a kind of controlling device, relates 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.
Model utility content
The utility model object provides a kind of assemble easy, that pretightening force is adjustable ball valve controlling device to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: 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 utility model compared with prior art has following advantages:
A kind of ball valve controlling device of the utility model scheme, 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 solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of a kind of ball valve controlling device of the present utility model;
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 drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of ball valve controlling device described in the utility model, 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 utility model scheme, 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.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
