Abstract
The utility model discloses a kind of fluoroplastic lining gate valve, described valve body is fixed on valve seat by nut, described valve gap is arranged on the joint of flashboard and valve body, described flashboard is fixed on valve body, described valve rod is arranged on the upper end of flashboard, and be connected with valve body and valve seat, described valve seat insert is arranged on the groove of valve seat.The utility model adds valve seat insert, and valve seat insert and flashboard are designed to detachable, and the sealing surface of valve seat insert and flashboard can be processed, and sealability improves about about 30% than original.Valve seat insert and flashboard replaceable, valve seat insert and flashboard can be used as easily damaged parts buying, reduce user purchase cost about 30% ~ 50%, can make improve 2 ~ 3 times the working life of whole gate valve.Add the structure of the anti-high vacuum of steel shell inwall, namely on gate valve steel shell inwall, be welded with steel wire, the shaping rear fluoroplastic of plastic lining and steel wire are fused into one and is close on gate valve steel inwall, gate valve can be worked under authentic reciprocal of duty cycle.
Description
Technical field
the utility model relates toand gate valve neck
territory, especially a kind of fluoroplastic lining gate valve.
Background technique
In the occasion of the conveying corrosive fluid medium such as heavy chemical industry, large chemical fertilizer, petroleum and petrochemical industry, smelting iron and steel, metal valve is because can be corroded, obviously cannot use, therefore in this kind of occasion, usually the valve using fluoroplastics lining is needed, and existing fluoroplastics lining valve is as fluoroplastic lining gate valve, due to the reason of its structure, difficulty of processing is large, valve body sealing surface cannot be processed, still requirement can be reached for its sealing of small-bore fluoroplastic lining gate valve, but for heavy caliber fluoroplastic lining gate valve, its sealability cannot reach seal request.Once valve body sealing surface and flashboard damage, and whole deck valve door is scrapped, and be affixed on gate valve steel shell inwall because of plastic lining nexine pine, can not practicality run under a high vacuum.
Summary of the invention
For the problems referred to above, the utility model aims to provide a kind of good seal performance, the fluoroplastic lining gate valve that economical and practical, corrosion resistance is high.
For realizing this technical purpose, scheme of the present utility model is:
A kind of fluoroplastic lining gate valve, comprise valve body, valve gap, valve seat, flashboard, valve rod and valve seat insert, described valve body is fixed on valve seat by nut, described valve gap is arranged on the joint of flashboard and valve body, described flashboard is fixed on valve body, described valve rod is arranged on the upper end of flashboard, and is connected with valve body and valve seat, and described valve seat insert is arranged on the groove of valve seat.
As preferably, the inwall of described valve body is welded with steel wire, is connected with fluoroplastic by steel wire, be close on the inwall of valve body.
As preferably, described valve gap, valve seat, flashboard, valve rod and valve body are all provided with perfluoroethylene-propylene clad in the position of steel skeleton outer contacting fluid.
As preferably, the sealing installation place of described valve seat and valve body is provided with groove.
As preferably, described flashboard and valve rod adopt removably separation design.
As preferably, described valve seat insert and valve body adopt removably separation design.
The utility model adds valve seat insert on the basis of former fluoroplastic lining gate valve, and valve seat insert and flashboard are designed to detachable, and the sealing surface of valve seat insert and flashboard can be processed, and sealability improves about about 30% than original.Valve seat insert and flashboard replaceable, the call of response national energy-saving, valve seat insert and flashboard can be used as easily damaged parts buying, reduce user purchase cost about 30% ~ 50%, can make improve 2 ~ 3 times the working life of whole gate valve.The basis of former fluoroplastic lining gate valve adds the structure of the anti-high vacuum of steel shell inwall, namely on gate valve steel shell inwall, steel wire is welded with, the shaping rear fluoroplastic of plastic lining and steel wire are fused into one be close on gate valve steel inwall, gate valve can be worked under authentic reciprocal of duty cycle.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
Embodiment
below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, a kind of fluoroplastic lining gate valve of the utility model embodiment, comprise valve body 1, valve gap 2, valve seat 3, flashboard 4, valve rod 5 and valve seat insert 6, described valve body 1 is fixed on valve seat 3 by nut, described valve gap 2 is arranged on the joint of flashboard 4 and valve body 1, and described flashboard 4 is fixed on valve body 1, and described valve rod 5 is arranged on the upper end of flashboard 4, and be connected with valve body 1 and valve seat 3, described valve seat insert 6 is arranged on the groove of valve seat 3.
As preferably, the inwall of described valve body 1 is welded with steel wire, is connected with fluoroplastic by steel wire, be close on the inwall of valve body 1.
As preferably, described valve gap 2, valve seat 3, flashboard 4, valve rod 5 and valve body 1 are all provided with perfluoroethylene-propylene clad in the position of steel skeleton outer contacting fluid.
As preferably, described valve seat 3 is provided with groove with the sealing installation place of valve body 1.
As preferably, described flashboard 4 adopts removably separation design with valve rod 5.
As preferably, described valve seat insert 6 adopts removably separation design with valve body 1.
The utility model adds valve seat insert 6 on the basis of former fluoroplastic lining gate valve, and valve seat insert 6 and flashboard 4 are designed to detachable, and the sealing surface of valve seat insert 6 and flashboard 4 can be processed, and sealability improves about about 30% than original.The basis of former fluoroplastic lining gate valve adds the structure of the anti-high vacuum of steel shell inwall, namely on gate valve steel shell inwall, steel wire is welded with, the shaping rear fluoroplastic of plastic lining and steel wire are fused into one be close on gate valve steel inwall, gate valve can be worked under authentic reciprocal of duty cycle.Have extraordinary antiseptic property, inner ring is steel skeletal structure, then make valve body 1, valve seat 3 and flashboard 4 have good intensity, is very suitable for bigbore etch-proof working condition uses.Valve seat 3 and valve body 1 are separation structures, and valve seat 3, valve seat insert 6 and flashboard 4 are replaceable, can be used as easily damaged parts buying, reduce user's purchase cost about 30% ~ 50%, can make improve 2 ~ 3 times the working life of whole gate valve.Flashboard 4 and valve rod 5 are separation structures, are conducive to production and the manufacture of heavy caliber fluoroplastic lining gate valve.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, the protection domain of technical solutions of the utility model all should be included in
within.
