Description
Technical field
The utility model relates to a kind of safety valve Cock screw, is specifically related to a kind of adjustable Cock screw of sealed relief valve Adjusting ring completely.
Background technique
The sealing configuration of existing fully-enclosed safe valve regulation circle Cock screw all adopts and is wound around raw meal belt sealing; such sealing means in use often there will be leakage; if service time, slightly length also can cause the problem that screw rust is dead, cannot screw out; the teeth of screw and screw can be caused time serious damaged; replacing and the adjustment of component cannot be carried out, make valve add cost in working service process.
Model utility content
The purpose of this utility model is for above-mentioned Problems existing and deficiency, provides a kind of reasonable in design, good seal performance, the adjustable Cock screw of length-adjustable complete sealed relief valve Adjusting ring.
For achieving the above object, the technological scheme taked is:
A kind of adjustable Cock screw of sealed relief valve Adjusting ring completely, comprise the Adjusting ring that is sleeved on valve seat top and be arranged on Cock screw corresponding with Adjusting ring on valve body, described Cock screw comprises bolt body, described bolt body end axis is to offering screw, in described screw, coupling is provided with one end section of being threaded the other end is the screw of addendum cone, the thread section of screw is also arranged with a parallel nut.
Described valve body offers annular groove with bolt body corresponding position, between the nut of described bolt body and annular groove, is arranged with sealing gasket and metal plain cushion.
Described sealing gasket is polytetrafluoroethylene sealing gasket.
Adopt technique scheme, acquired beneficial effect is:
The utility model adopts the Cock screw of new its length adjustable of structure, overcomes the problem different in size brought due to blank defect; With polytetrafluoroethylsealed sealed pad and metal plain cushion as sealing configuration, make sealability more superior, ensure the polytetrafluoroethylsealed sealed pad not irregular diffusion deformation because of cold flow properties simultaneously, ensure that sealing and anti-loosening property.
Accompanying drawing explanation
Fig. 1 is positional structure schematic diagram of the present utility model.
Fig. 2 is structure for amplifying schematic diagram of the present utility model.
Sequence number in figure: 1 be valve seat, 2 be Adjusting ring, 3 be valve body, 4 be bolt body, 5 be screw, 6 be parallel nut, 7 be sealing gasket, 8 be metal plain cushion.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
See Fig. 1, Fig. 2, a kind of adjustable Cock screw of sealed relief valve Adjusting ring completely of the utility model, comprise the Adjusting ring 2 that is sleeved on valve seat 1 top and be arranged on Cock screw corresponding with Adjusting ring 2 on valve body 3, described Cock screw comprises bolt body 4, described bolt body 4 end axis is to offering screw, in described screw, coupling is provided with the screw 5 that one end section of being threaded the other end is addendum cone, the thread section of screw 5 is also arranged with a parallel nut 6.
Described valve body 3 offers annular groove with bolt body 4 corresponding position, is arranged with sealing gasket 7 and metal plain cushion 8 between the nut of described bolt body 4 and annular groove, described sealing gasket is polytetrafluoroethylene sealing gasket.
The utility model adopts the Cock screw of new its length adjustable of structure, overcomes the problem different in size brought due to blank defect; With polytetrafluoroethylsealed sealed pad and metal plain cushion as sealing configuration, make sealability more superior, ensure the polytetrafluoroethylsealed sealed pad not irregular diffusion deformation because of cold flow properties simultaneously, ensure that sealing and anti-loosening property.
