Abstract
The invention discloses an adjustable sealing valve which comprises a valve body and a valve seat. The valve body is installed in the valve seat. An adjusting seat is arranged outside the valve seat. An adjusting bent rod is arranged in the adjusting seat. One end of the adjusting bent rod stretches out of the adjusting seat, and the other end of the adjusting bent rod stretches into the valve body. A compression spring is arranged between the adjusting bent rod and the inner wall of the adjusting seat. A sealing layer is further arranged between the valve body and the valve seat. According to the scheme, the adjusting seat is arranged outside the valve seat, the adjusting bent rod is arranged in the adjusting seat, one end of the adjusting bent rod stretches out of the adjusting seat, the other end of the adjusting bent rod stretches into the valve body and the compression spring is arranged between the adjusting bent rod and the inner wall of the adjusting seat, so that in the use process, the position of the adjusting bent rod in the valve body is controlled by pressing the adjusting bent rod on the adjusting seat; the compression spring plays the vibration reduction and tightening roles, and the overall pre-tightening force can be adjusted; meanwhile, the adjusting seat is arranged outside the valve body, and assembling is easy; and the sealing layer is further arranged between the valve body and the valve seat to be used for reinforcing the sealing performance of the valve body and preventing leakage.
Description
Technical field
The present invention relates to a kind of controlling device, relate to a kind of adjustment sealed valve body 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 adjustment sealed valve body: 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 adjustment sealed valve body.
Technical solution of the present invention is achieved in that a kind of adjustment sealed valve body, comprises valve body, valve seat; Described valve body is arranged in valve seat; Described valve seat outside is provided with adjustment seat; Adjustment knee is provided with in described adjustment seat; Adjustment seat is stretched out in described adjustment knee one end, and the other end stretches into valve inner; Compress Spring is provided with between described adjustment knee and adjustment seat inwall; Also sealing layer is provided with between described valve body and valve seat.
Preferably, described adjustment seat one has four.
Preferably, described valve body is made up of stainless steel.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
One of the present invention regulates sealed valve body, by will in valve seat outer installment adjustment seat, adjustment knee is established in adjustment seat, knee one end is regulated to stretch out adjustment seat, the other end stretches into valve inner, regulate between knee and adjustment seat inwall and be provided with Compress Spring, during use, pressing adjustment knee in adjustment seat can the position of regulating and controlling knee in valve body, Compress Spring plays the effect of damping and degree of tightness, overall pretightening force can be adjusted, simultaneously to be arranged on valve body simply exterior for adjustment seat, sealing layer is also provided with for strengthening the sealing of valve body between valve body and valve seat, prevent from revealing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is a kind of structural representation regulating sealed valve body of the present invention;
Wherein: 1, valve body; 2, valve seat; 3, adjustment seat; 4, knee is regulated; 5, Compress Spring; 6, sealing layer.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is that one of the present invention regulates sealed valve body, 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 adjustment seat 3; Be provided with in described adjustment seat 3 and regulate knee 4; Adjustment seat 3 is stretched out in described adjustment knee 4 one end, and it is inner that the other end stretches into valve body 1; Compress Spring 5 is provided with between described adjustment knee 4 and adjustment seat 3 inwall; Sealing layer 6 is also provided with between described valve body 1 and valve seat 2; Described adjustment seat 3 one has four; Described valve body 1 is made up of stainless steel.
The one of the present invention program regulates sealed valve body, by will in valve seat 2 outer installment adjustment seat 3, establish in adjustment seat 3 and regulate knee 4, knee 4 one end is regulated to stretch out adjustment seat 3, it is inner that the other end stretches into valve body 1, regulate between knee 4 and adjustment seat 3 inwall and be provided with Compress Spring 5, during use, pressing adjustment knee 4 in adjustment seat 3 can the position of regulating and controlling knee 4 in valve body 1, Compress Spring 5 plays the effect of damping and degree of tightness, overall pretightening force can be adjusted, simultaneously to be arranged on valve body 1 simply exterior for adjustment seat 3, sealing layer 6 is also provided with for strengthening the sealing of valve body 1 between valve body 1 and valve seat 2, prevent from revealing.
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.
