Abstract
The utility model relates to a top entry ball valve with a fixed ball. The top entry ball valve with the fixed ball comprises a valve body and a valve seat, wherein the valve seat is installed on the valve body, a spring seat is arranged on the valve seat, a compression spring is arranged between the spring seat and the valve seat, the degree of tightness between the spring seat and the valve seat can be adjusted through adjusting nuts, and a sealing ring is arranged between the valve seat and the valve body. According to the scheme, due to the fact that the adjusting nuts are arranged between the valve seat and the spring seat, the compression spring is compressed in the spring seat, and a valve seat assembly is installed in the valve body; due to the fact that the compression spring is compressed before the ball is installed, the ball can be conveniently installed; due to the facts that after the ball is assembled, the adjusting nuts are withdrawn from the spring seat, pre-tightening force of the compression spring to the ball is small at the moment, and when the pre-tightening force needs increasing, adjustment can be carried out through the adjusting nuts, the purposes that the top entry ball valve with the fixed ball is conveniently assembled, and the pre-tightening force is adjustable can be achieved.
Description
Technical field
The utility model relates to a kind of ball valve, relates to specifically fixedly spherical ball valve of a kind of upper dress formula.
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, easy to maintenance quick, when valve breaks down need to repair time on pipeline, needn't dismantle valve from pipeline, need only dismantle flange bolt and nut, valve gap is taken off together with valve rod group component from valve body, then take out spheroid and valve seat combination part, can repair online spheroid and valve seat, the time has been saved in maintenance like this, but there are some shortcomings in existing upper dress formula fixedly spherical ball valve: initial tension of spring can not be adjusted and control, and when assembling amount of spring compression large, assembling difficulty.
Model utility content
The utility model object is that a kind of fixedly spherical ball valve of the upper dress formula easy, pretightening force is adjustable that assembles is provided in order 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 upper dress formula is spherical ball valve fixedly, comprises valve body, valve seat, and described valve seat is arranged on valve body, and described valve seat is provided with spring seat; Between described spring seat and valve seat, be provided with Compress Spring; Described spring seat and valve seat can pass through adjusting nut adjusting elasticity; Between described valve seat and valve body, be provided with seal ring.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of upper dress formula of the utility model scheme is spherical ball valve fixedly, by adjusting nut being set between valve seat and spring seat, Compress Spring is pressed in spring seat, pack valve seat combination part into valve body, because Compress Spring before spheroid is installed is compressed, described installation spheroid is very convenient, after spheroid assembling, adjusting nut is exited to spring seat, now Compress Spring is less for the pretightening force of spheroid, and when needs increase pretightening force, available adjusting nut is adjusted, so just realized 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 fixedly structural representation of spherical ball valve of a kind of upper dress formula of the present utility model;
Wherein: 1, valve body; 2, valve seat; 3, spring seat; 4, Compress Spring; 5, adjusting nut; 6, seal ring.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is fixedly spherical ball valve of a kind of upper dress formula described in the utility model, comprises valve body 1, valve seat 2, and described valve seat 2 is arranged on valve body 1, and described valve seat 2 is provided with spring seat 3; Between described spring seat 3 and valve seat 2, be provided with Compress Spring 4; Described spring seat 3 can pass through adjusting nut 5 adjusting elasticities with valve seat 2; Between described valve seat 2 and valve body 1, be provided with seal ring 6.
The utility model scheme by arranging adjusting nut 5 between valve seat 2 and spring seat 3, Compress Spring 4 is pressed in spring seat 3, pack valve seat 2 assembly parties into valve body 1, because Compress Spring 4 before spheroid is installed is compressed, described installation spheroid is very convenient, after spheroid assembling, adjusting nut 5 is exited to spring seat 3, now Compress Spring 4 is less for the pretightening force of spheroid, when needs increase pretightening force, available adjusting nut 4 adjusts, and so just realized the convenience of ball valve assembling, pretightening force adjustable.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
