Abstract
The utility model relates to a corrosion-resistant valve, which is composed of a valve body, a valve core, a valve cover and a valve rod. The utility model is characterized in that a special structure three-way rubber tube is arranged in the valve body which is composed of a right and a left half parts. A rubber diaphragm closing element is arranged above a vertical branch pipe of the three-way pipe. The rubber diaphragm closing element is composed of a rubber diaphragm, a valve core, a valve cover and a valve rod and can generate flexible deformation. The three-way pipe is inserted with a metal skeleton which can reinforce the rigidity of the three-way pipe. Compared with an existing diaphragm valve, an existing pipe clamp valve and an existing cut-off valve, the utility model has the advantages of reliable seal, simple structure, convenient maintenance, anticorrosive performance, long service life and wide use.
Description
The utility model relates to the anticorrosion valve of a kind of new structure, belongs to anticorrosion valve type, is particularly useful for carrying in the industries such as chemical industry, metallurgy, dyestuff, agricultural chemicals, oil the medium that is corrosive.
Anticorrosion valve commonly used has membrane valve and the pipe clip valve that serves as a contrast rubber or serve as a contrast other nonmetallic material in the present above-mentioned industry.But, need press the on-the-spot liner rubber of valve body and difficult being extensive use of because the membrane valve valve body is complicated; Though and the pipe clip valve valve body needn't on-the-spotly serve as a contrast rubber, has been substituted by rubber pipe; But because rubber pipe is out of shape greatlyyer when open and close, plastic deformation very easily takes place, thereby influence working life; For general stop valve commonly used, because it is complex-shaped, be difficult to liner rubber, adding needs ad hoc seal arrangement, so seldom be used for carrying the medium that is corrosive.
The purpose of the present utility model is to provide a kind of novel anticorrosion valve, wishes that it can overcome the deficiency of traditional stop valve, membrane valve and pipe clip valve; Simultaneously can gather their advantage effectively again, forms a kind of seal reliable, simple in structure, maintenance makes things convenient for, the anticorrosion valve of long service life.
Above purpose is achieved through the following technical solutions:
The anticorrosion valve of this new structure is made up of valve body (6), spool (5), valve gap (3), valve rod (9), it is characterized in that being provided with in the described valve body (6) the threeway rubber pipe (7) of a polymorphic structure; Vertical branched pipe top at this threeway rubber pipe (7) is being provided with the diaphragm of rubber closure member of being made up of diaphragm of rubber (4), spool (5), valve gap (3), valve rod (9) that can produce the flexible deformation; Being U type bottom, setting the spool (5) that is one with barrier film of wherein said diaphragm of rubber (4), and the valve rod (9) through being connected with spool (5) passes valve gap (3) center and handwheel (1) bolt; The circular upper periphery of described diaphragm of rubber (4) then is located in the connecting part of valve body (6) and valve gap (3).
Described valve body (6) partly is spirally connected by two halfbodies and forms.
Inlaying metal frame (8) in the described threeway rubber pipe (7).
Described valve gap (3) goes up, be nested with the spacer (2) of may command diaphragm of rubber appropriateness amount of deformation when closing around valve rod (9).
Compare with existing all kinds of corrosion resistant valves according to the anticorrosion valve of new structure that technique scheme is formed, have that sealing is reliable, simple in structure, maintenance is convenient, arranged long working life.Neither resemble and want on-the-spot liner rubber the conventional membrane valve, also avoid traditional pipe clip valve that the defective of plastic deformation easily takes place; Simultaneously also overcome the not weakness of corrosion resistant of general stop valve, really accomplish to learn wildly from other's strong points.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is that the AA of accompanying drawing 1 is to cut-away view.
Further describe the utility model and provide embodiment below in conjunction with accompanying drawing.
The anticorrosion valve of new structure as shown in FIG. mainly is made up of handwheel (1), spacer (2), valve gap (3), diaphragm of rubber (4), spool (5), valve body (6), three-way pipe rubber (7), metal frame (8), valve rod (9) etc.; Its described valve body (6) is divided into left and right sides two halves, connect into integral body by bolt, special-shaped t-bend rubber pipe (7) is being set in this valve body (6),, in the rubber body of its corresponding site, is being inlaid with metal frame (8) for strengthening this threeway rubber pipe (7) sealing position rigidity.In the vertical branched pipe top of this threeway rubber pipe (7) the diaphragm of rubber closure member of being made up of diaphragm of rubber (4), spool (5), valve gap (3), valve rod (9) that can produce the flexible deformation is being set simultaneously.Wherein be diaphragm of rubber (4) bottom of U type, setting the spool (5) that is one with barrier film, and the valve rod (9) through being connected with spool (5) pass valve gap (3) center and handwheel (1) bolt; The circular upper periphery of described diaphragm of rubber (4) then is folded in the connecting part of valve body (6) and valve gap (3).
Anticorrosion valve shown in the accompanying drawing 1 is closed condition, when opening, only need turn handwheel (1) to mention valve rod (9), along with carrying on this valve rod (9), the spool (5) that is embedded at diaphragm of rubber (4) is being with diaphragm of rubber (4) also to move on synchronously thereupon, this valve body is in open to enter working state, and mouthful increases and enlargement discharge along with opening.In case need throttle down, as long as reverse turn handwheel (1), make valve rod (9) migration downwards, and the rubber film barrier film (4) that thereupon also drives valve rod (9) front end moves down, in case when its U type front portion propped up the vertical arm of threeway rubber pipe (7), valve body promptly was in closed condition.
In order to strengthen the supportive of threeway rubber pipe (7), so must inlay rigid support at corresponding site; Simultaneously in order to keep the elastic deflection of diaphragm of rubber, the spacer (2) of the appropriate amount of deformation of may command diaphragm of rubber (4) when the pass valve being set on the top of valve gap (3); Described valve gap (3) is connected by bolt with valve body (6).
Claims (4)
1, the anticorrosion valve of a kind of new structure is made up of valve body (6), spool (5), valve gap (3), valve rod (9), it is characterized in that being provided with in the described valve body (6) the threeway rubber pipe (7) of a polymorphic structure; Vertical branched pipe top at this threeway rubber pipe (7) is being provided with the diaphragm of rubber closure member of being made up of diaphragm of rubber (4), spool (5), valve gap (3), valve rod (9) that can produce the flexible deformation; Being bottom the U type of wherein said diaphragm of rubber (4), setting the spool (5) that is one with barrier film, and the valve rod (9) through being connected with spool (5) passes valve gap center and handwheel (1) bolt; The circular upper periphery of described diaphragm of rubber (4) then is located in the connecting part of valve body (6) and valve gap (3).
