Abstract
The invention discloses a top-mounted ball valve with a fixed ball. The top-mounted ball valve with the fixed ball comprises a valve body and a valve seat. 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. An adjusting nut is used for adjusting tightness between the spring seat and the valve seat. A sealing ring is arranged between the valve seat and the valve body. According to the top-mounted ball valve with the fixed ball, the adjusting nut is arranged between the valve seat and the spring seat and compresses the compression spring into the spring seat. A valve seat assembly is installed into the valve body and a ball body is conveniently installed as the compression spring is compressed in advance. When the ball body is assembled, the adjusting nut is withdrawn from the spring seat and pretightening force of the compression spring on the ball body is small. When pretightening force needs boosting, the adjusting nut can be used for adjusting and thus, the ball valve is convenient to assemble and the pretightening force can be adjusted.
Description
Technical field
The present invention relates to a kind of ball valve, relate to a kind of fixedly spherical ball valve of dress formula of going up specifically.
Background technique
Upper-mounting type ball valve extensively is used on the 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 rapidly simple in the pipeline dismounting, easy to maintenance quick, when valve breaks down when need repairing at pipeline, needn't dismantle valve from pipeline, need only dismantle flange bolt and nut, valve gap and valve rod group component are taken off from valve body together, take out spheroid and valve seat combination part then, get final product online repairing spheroid and valve seat, the time has been saved in maintenance like this, but existing go up the dress formula fixedly spherical ball valve have some shortcomings: initial tension of spring can not be adjusted and control, and amount of spring compression is big during assembling, and assembling is difficult.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: proposed a kind of fixedly spherical ball valve of the last dress formula easy, that pretightening force is adjustable that assembles.
Technical solution of the present invention is achieved in that a kind of fixedly spherical ball valve of dress formula of going up, and comprises valve body, valve seat, and described valve seat is installed on the valve body, and described valve seat is provided with spring seat; Be provided with the compression spring between described spring seat and the valve seat; Described spring seat and valve seat can be regulated degree of tightness by adjusting nut; Be provided with seal ring between described valve seat and the valve body.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
A kind of fixedly spherical ball valve of dress formula of going up of the present invention, by the adjustment nut is set between valve seat and spring seat, to compress spring compression in spring seat, with the valve seat combination part valve body of packing into, because it is compressed to compress spring before the installation spheroid, described installation spheroid is very convenient, after the spheroid assembling, to adjust nut and withdraw from spring seat, it is less for the pretightening force of spheroid that compress spring this moment, and when needs increased pretightening force, available adjustment nut was adjusted, so just realized the convenience of ball valve assembling, pretightening force adjustable.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is a kind of fixedly structural representation of spherical ball valve of dress formula of going up of the present invention;
Wherein: 1, valve body; 2, valve seat; 3, spring seat; 4, compression spring; 5, adjust nut; 6, seal ring.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a kind of fixedly spherical ball valve of dress formula of going up of the present invention, comprises valve body 1, valve seat 2, and described valve seat 2 is installed on the valve body 1, and described valve seat 2 is provided with spring seat 3; Be provided with compression spring 4 between described spring seat 3 and the valve seat 2; Described spring seat 3 can be regulated degree of tightness by adjusting nut 5 with valve seat 2; Be provided with seal ring 6 between described valve seat 2 and the valve body 1.
The present invention program adjusts nut 5 by arranging between valve seat 2 and spring seat 3, to compress spring 4 is pressed in the spring seat 3, with the valve seat 2 assembly parties valve body 1 of packing into, because it is compressed to compress spring 4 before the installation spheroid, described installation spheroid is very convenient, after the spheroid assembling, to adjust nut 5 and withdraw from spring seat 3, it is less for the pretightening force of spheroid that compress spring 4 this moment, when needs increase pretightening force, available adjustment nut 4 adjusts, and so just realized the convenience of ball valve assembling, pretightening force adjustable.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (1)
