Description
Technical field
It the utility model is related to valve technology field, more particularly to a kind of anticorrosion flow control valve.
Background technology
Ball valve is mainly used for cutting off, distribute and changing the flow direction of medium in pipeline, can be closed by rotating ball valve
Close or open the circulation of medium.Existing ball valve makees opening and closing element to be a kind of with the sphere with circular through hole, and core is with valve rod
Rotate, to realize the valve of switching motion.And the sphere of the ball valve is mainly by body and the interface channel on body, body
The upper axial both ends positioned at interface channel, which are respectively equipped with, promotes traffic channel and the opening of extraneous conducting, due to the cross section of opening
Consistent with the cross section of interface channel, i.e., its diameter is identical, and the flow-rate adjustment of ball valve relies on valve rod spinning ball, due on sphere
The bore of interface channel is larger, can not realize more accurate and trickle flow-rate adjustment.And the ball-valve structure is complicated, volume
Greatly, the defects of sphere and sealing surface are more open, not compact enough, and leakage point is more, poor sealing, valve fits badly.
In the operating mode that some absolutely not allow medium to reveal, such as poisonous medium, it is particularly severe to the leakproofness of valve,
Much better than general sealing property of ball valves of hemispherical sealing property of ball valves, can reach defined requirement.The valve of existing hemispherical ball valve
Seat is fabricated for metal material, and metal sealing is carried out using hard metal valve seat.But the metal seat valve is during use,
If run into poisonous medium caustically, valve seat erosion, damage can be caused, influences the sealing performance of its sealing effect and valve.
Utility model content
The purpose of this utility model is that being the defects of overcoming the prior art, and provide a kind of more compact structure, Neng Goufang
The only anticorrosion flow control valve of burn into reliability, better tightness.
To achieve the above object, the utility model uses following technical scheme：A kind of anticorrosion flow control valve, including valve
Body, the valve body are equipped with passage, medium inlet and media outlet, and the medium inlet is connected by passage and media outlet
Connect, ball valve is equipped with the passage of the valve body, the inner wall between the valve channel and media outlet is equipped with step, described
Rank is equipped with valve component, and the valve component includes the soft valve seat of fixation with the ball valve opposing seal, fixed soft valve seat
Polytetrafluorethylecoatings coatings are set on outer surface.
Further, the soft valve seat of the fixation is equipped with annular groove close to the port of the ball valve.
Further, the annular groove is built-in is embedded with elastic sealing element.
Further, the elastic sealing element is graphite seal.
Further, the ball valve is half valve fixing ball valve.
The beneficial effect of the utility model compared with prior art is：The anticorrosion flow control valve of the utility model passes through
Etch-proof polytetrafluorethylecoatings coatings are coated with the outer surface of the soft valve seat of fixation, run into fixed soft valve seat mordant
It will not be damaged during poisonous medium, fixed soft valve seat, and assembly has bullet on the port contacted by the soft valve seat of fixation with ball valve
Property seal so that fixed soft valve seat, which can compress, to be fitted on the sphere of ball valve, and then improves the leakproofness of valve.
Brief description of the drawings

Embodiment
In order to more fully understand the technology contents of the utility model, the skill with reference to specific embodiment to the utility model
Art scheme is described further and illustrates.
The concrete structure of the utility model embodiment is as illustrated in fig. 1 and 2；A kind of anticorrosion flow control valve, including valve body
1, valve body 1 is equipped with passage 7, medium inlet 8 and media outlet 9, and medium inlet 8 is connected by passage with media outlet 9, valve
Ball valve 2 is equipped with the passage 7 of body 1, the inner wall between 1 passage 7 of valve body and media outlet 9 is equipped with step 10, is set on step 10
There is valve component 3, valve component 3 includes the soft valve seat 4 of fixation with 2 opposing seal of ball valve, set on the outer surface of fixed soft valve seat 4
Polytetrafluorethylecoatings coatings are put, wherein, polytetrafluoroethylene (PTFE) has corrosion-resisting function, fixes the elastic sealing element on the port of soft valve seat
6 can be close to seal with the surface of ball valve 2.
Preferably, fixed soft valve seat 4 is equipped with annular groove 5 close to the port of ball valve 2.
Preferably, annular groove 5 is built-in is embedded with elastic sealing element 6.
Preferably, elastic sealing element 6 is graphite seal.
Preferably, ball valve 2 is half valve fixing ball valve.
The anticorrosion flow control valve of the utility model is etch-proof by being coated with the outer surface of the soft valve seat of fixation
Polytetrafluorethylecoatings coatings, making to fix when soft valve seat runs into mordant poisonous medium to damage, fixed soft valve seat, and
The flexible seal of assembly on the port contacted by the soft valve seat of fixation with ball valve so that fixed soft valve seat, which can compress, to be fitted in
On the sphere of ball valve, and then improve the leakproofness of valve.
The technology contents set forth above that the utility model is only further illustrated with embodiment, in order to which reader is easier to manage
Solution, but the embodiment for not representing the utility model is only limitted to this, and any technology done according to the utility model extends or creates again
Make, protected by the utility model.
