Description

Valve for fluid

Technical field

The present invention relates to a kind of valve for fluid, refer to a kind of structure innovation that can be applied to the valve for fluid of various structures especially, the present invention mainly is that the coupling collar in body encloses the one-body molded one or more metal ring that is coated with; Coupling collar in loam cake or joint encloses the one or more metal ring of one-body molded coating again, so, when body with after loam cake or joint combine, must be born bigger hydrodynamic pressure by to be allowed valve for fluid, improve the working life of valve for fluid, and can extensively be applied to various field of employment.

Background technique

By commercially available valve for fluid, as shown in Figure 1, be to explain conventional construction with diaphram valve, it comprises: body 1, establish integrated fluid circulating hole 10 in the inside of body 1, and be positioned at the central authorities of fluid circulating hole 10 and be provided with flange 11, utilize this flange 11 and valve block collocation to operate with opening/shutting valve, whether the decision fluid flow to be.Be positioned at the both sides of body 1 again and establish convergence part 12, in the convergence part 12 establish the ring enclose 120, utilize this ring enclose 120 with the pipe fitting combination that is connected.Be positioned at the central authorities of body 1 and the coupling collar of establishing loam cake 2 again and enclose 14, this coupling collar encloses 14 inboard and establishes hole 140.

Loam cake 2, establish valve block 20 in loam cake 2 belows, the central authorities of aforementioned valve block 20 and valve rod 21 are connected with, and valve block 20 is established ring and is enclosed 200, like this must the utilization sets firmly assembly 22 coupling collar of loam cake 2 enclosed 23, the ring of valve block 20 enclose 200 and the coupling collar of aforementioned body 1 enclose 14 and be combined as a whole, and for allowing diaphram valve must bear big pressure, be that coupling collar in loam cake 2 encloses 23 tops and is provided with arc metal plate 24, arc metal plate 24 has suitable perforation 240 and must think and aforementionedly set firmly that assembly 22 passes and bolt is solid, again by operating valve lever 21 to open and close valve block 20, can make the valve block 20 and flange 11 collocation of aforesaid fluid opening 10 operate, whether the decision fluid flow.

Only the structure common drawback of various known valve for fluid or valve is: aforementioned known valve for fluid loam cake 2 set tinsels 24 are arc shape, and must form by multi-disc, tinsel 24 and can't with the loam cake structure that is combined into one, as described above, hydrodynamic pressure can be attacked the fragile position of diaphram valve, and valve block 20 is attacked part with the binding site of body 1, make known diaphram valve because can't bear hydrodynamic pressure and breakage, allow fluid leak, and aforementioned metal sheet 24 is exposed to the outside, if this valve for fluid is applied to acid, when alkaline fluids or environment, tinsel 24 is subject to acid, alkaline fluids is attacked quick corrosion, reduces the working life and the exercisable place of restriction of diaphram valve.

For this reason, the present inventor, design, research and development and the manufacturing experience of product ten yearly correlation valve for fluid, special at the shortcoming of preceding taking off known person, studied and invention this case.

Summary of the invention

The valve for fluid that provides a kind of structure more to strengthen is provided purpose of the present invention, allows the valve for fluid of various structures, as membrane valve; Or by appointing the formula membrane valve; Or swing type membrane valve; Or check valve; Or the coupling collar of the body of butterfly valve encloses the one-body molded metal ring that has; And lid or the coupling collar of joint enclose the also one-body molded metal ring that has thereon, when body and loam cake; Or body born bigger hydrodynamic pressure by to be allowed valve for fluid with after joint combines, and improves its working life and field of employment.

The object of the present invention is achieved like this, and a kind of valve for fluid is to establish fluid circulating hole in body, establishes coupling collar in body and enclose, and this coupling collar encloses the one-body molded one or more metal ring that is coated with.

Valve for fluid of the present invention, enclose and the one or more metal ring of one-body molded coating in the coupling collar of loam cake or joint, so, when body with after loam cake or joint combine, valve for fluid can bear bigger hydrodynamic pressure, improves its working life and field of employment.

Valve for fluid of the present invention also must coat the metal ring more than one or in the convergence part of the body both sides of various valve, the working life of improving valve for fluid again.

Advantage of the present invention is: when body with after loam cake combines; Or body born bigger hydrodynamic pressure by to be allowed valve for fluid with after joint combines, and improves its working life and place applicatory is more.
