Description
Technical field
The utility model relates to a kind of mesohigh bellows stop valve, belongs to valve type.
Background technique
At present, existing General valve, though closure member can solve the switching problem of flowing medium in the pipeline, but medium can be along valve rod when opening state, leak into the valve body outside by stuffing box packing, cause valve body to produce the phenomenon of run, drip, leak, particularly along with the phenomenon of this run, drip, leak of increase of pressure medium is also just even more serious; In addition, the closure member of existing stop valve all is that plane or cone combine with valve seat or divide and open closing function, and its sealing surface is easy to wear, and the life-span lacks; Plane or grooved metal gasket are all adopted in existing universal valve body and valve bonnet seal, and withstand voltage low, high temperature media can reduce sealability; Existing low pressure bellows stop valve generally uses below 1MPA, can not bear the above pressure of 1MPA, and existing in a word stop valve is not ideal enough.
Summary of the invention
It is tight that the purpose of this utility model is to design a kind of sealing, makes closure member with steel ball, is welded with bellows on the valve rod, is applicable to the bellows stop valve of mesohigh.
The purpose of this utility model is to realize like this, it is mainly by valve body (1), steel ball (2), O type circle (6), bellows (10), lower valve rod (11), upper valve rod (12), valve gap parts such as (21) are formed, the top that it is characterized in that valve body (1) is equipped with upper valve rod (12) and the lower valve rod (11) that is connected by non-magnetic shim (22), the bottom of lower valve rod (11) is provided with valve core housing (5) and steel ball (2), the upper end of bellows (10) is by lining outer pad of weldering (20) and the welding of upper valve rod (12) lower end, the lower end of bellows (10) is by welding pad (19) and middle contact pin (7) welding, middle contact pin (7) has 0 type circle (6), valve gap (21) by in connect cap (8) and locking nut (9) tightly covers on valve body (1), be with Packing seat (13) on the upper valve rod (12) respectively, filler (14) and filler pressure pad (15) also pass through pressure pad nut (16) buckle closure on valve gap (21), the upper tip of upper valve rod (12) is equipped with handle (18) by hexagon socket head cap screw (17), and the two ends of valve body (1) are equipped with adapter (3) by outer connected nut (4) respectively.
The utility model compared with prior art, its sealing is tight, long service life, the compressive strength height is a kind ofly can make that medium in no instance can be to the mesohigh bellows stop valve of external leakage in pipeline and the valve pocket.
Description of drawings
Accompanying drawing 1 is the whole sectional structure schematic representation of the utility model.
Wherein: 1, valve body, 2, steel ball, 3, take over, 4, outer connected nut, 5, valve core housing, 6, O type circle, 7, middle contact pin, 8, in connect cap, 9, locking nut, 10, bellows, 11, lower valve rod, 12, upper valve rod, 13, Packing seat, 14, filler, 15, the filler pressure pad, 16, the pressure pad nut, 17, hexagon socket head cap screw, 18, handle, 19, welding pad, 20, the outer pad of lining weldering, 21, valve gap, 22, non-magnetic shim.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to accompanying drawing: it mainly is made up of the utility model parts such as valve body 1, steel ball 2, O type circle 6, bellows 10, lower valve rod 11, upper valve rod 12, valve gaps 21, the top that it is characterized in that valve body 1 is equipped with upper valve rod 12 and the lower valve rod 11 that is connected by non-magnetic shim 22, here valve rod is divided into upper valve rod 12 and lower valve rod 11, when rotating upper valve rod 12, upper valve rod 12 produces axial displacement, be connected non-magnetic shim 22 by upper valve rod 12 with lower valve rod 11, make lower valve rod 11 produce axial displacement in the same way, valve closing member is opened, the function of closure and reach.The bottom of lower valve rod 11 is provided with valve core housing 5 and steel ball 2, and steel ball 2 is the steel ball of high temperature resistant high hardness, and can 360 ° of universal rotations, strengthens sealability, constantly changes potted line, increases the service life, and makes sealing keep closely permanent.The upper end of bellows 10 is by outer pad 20 of lining weldering and the welding of upper valve rod 12 lower ends, and the lower end of bellows 10 is by welding pad 19 and middle contact pin 7 welding, and bellows 10 is the multilayer corrugated stainless steel tubing, can make compressive strength bring up to 1.6～6.4MPa.It is hollow tubular stainless steel seal ring that middle contact pin 7 has O type circle 6,0 type circles 6, the sealing good springiness, and when temperature is high, air expansion, enhancing sealability in the hollow tubular.Valve gap 21 by in connect cap 8 and locking nut 9 tightly covers on valve body 1, be with Packing seat 13, filler 14 and filler pressure pad 15 on the upper valve rod 12 respectively and pass through pressure pad nut 16 buckle closures on valve gap 21, the upper tip of upper valve rod 12 is equipped with handle 18 by hexagon socket head cap screw 17, and the two ends of valve body 1 are equipped with by outer connected nut 4 respectively and take over 3.
