Background technique
At present, flow at convection cell, as be used for when the flow of current such as oil field pressure water injection is regulated and controlled, usually adopting traditional stop valve, they are valve body normally, be contained in the Stem Mut of valve body epicoele, seal ring and sealed pressing sleeve, be installed on Stem Mut, head in seal ring and the sealed pressing sleeve is fixed with the middle valve rod that is provided with screw thread of handwheel, the flap that has the conical sealing surface that the sealing surface with valve seat adapts that has the valve seat of conical sealing surface and be fixed on the valve rod end is formed, the valve seat of the valve of this structure and flap generally adopt cast iron to process, can meet the demands in the control fashion that is applied to non-high-pressure water flow flow, but when being used for the flow control of flowing to high pressure waters such as oil field pressure water injection, because high-pressure water flow is directly to valve seat with flap impacts and impact force is very big, its castiron valve seat and spool wear-corrosion resistance degree are poor, thereby wearing and tearing will appear in use soon, it is not closed completely, working life is very short, usually less than is 1 year, in order to address this problem, the pottery manufacturing valve seat of wear-corrosion resistance and the stop valve of spool have appearred on the market adopting, though it has solved the problem of valve seat and spool wear-corrosion resistance, but the intensity of ceramic material is low, and frangible difficult processing, so be difficult to extensive employing, in sum, the stop valve of above structure all can not satisfy the adjusting of the high-pressure water flow that looks like oil field pressure water injection one class and the application of control.
Summary of the invention
The utility model provides a kind of energy minimizing and tolerates impact and the abrasion of high-pressure water flow to valve seat and spool for solving the technical problem that exists in the known technology, can regulate control arbitrarily to the flow of high-pressure water flow, and the alloy flow modulating valve of long service life.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of alloy flow modulating valve, by the angie type valve body of outlet perpendicular to import, be contained in the Stem Mut of valve body epicoele, seal ring and sealed pressing sleeve, be installed on Stem Mut, head in seal ring and the sealed pressing sleeve is fixed with the middle valve rod that is provided with screw thread of handwheel, the flap that has the sealing surface that the sealing surface with valve seat adapts that is located at the valve seat that has sealing surface in the valve body and is located at the valve rod end is formed, described valve seat is located in the interior cavity of resorption of valve body, valve seat is cylindrical, have center hole and its sealing surface on it and be located at the upper end of center hole, the lower end of described flap has and can be deep in the valve base center hole and its periphery has the cylindrical current limliting core of several vertical current limliting grooves.
The utility model can also adopt following technical measures:
Described valve seat and flap are made by the high strength powder alloy.
Described valve seat is that close fit is fixedly mounted in the valve body cavity of resorption, and described flap is to adopt round boss to be set in the end of valve rod, to connect the upper end in the upper end of flap and have the mode that the center hole lower end has a sleeve shape free bearing of circular groove and be hinged on the valve rod end.
Described valve seat is that close fit is fixedly mounted in the valve body cavity of resorption, and described flap is an apical grafting in the valve rod end.
Have annular groove on the outer wall of described valve seat, be embedded with seal ring in the annular groove, valve seat is to be slidably mounted in the cavity of resorption of valve body, in the body cavity between described Stem Mut and valve seat spring is housed, and described flap is that apical grafting is in the valve rod end.
Advantage and the good effect that the utlity model has are: because valve seat of the present utility model is located in the valve body cavity of resorption, valve seat is cylindrical, have center hole and its conical sealing surface on it and be located at the upper end of center hole, have the cylindrical current limliting core that its periphery that can be deep in the valve base center hole has several vertical current limliting grooves on the termination of flap, thereby except can to high-pressure water flow regulate control also can play a part buffering to the impact of current, reduced the abrasion of current to sealing surface, and valve seat and spool and cylindrical current limliting core have adopted the high high strength powder alloy manufacturing of resistance to abrasion, so be particularly suitable for to sealing, wear-corrosion resistance, the application of shock-resistant demanding picture oil field pressure water injection one class, and can prolong working life of valve greatly.
