Description
Technical field
The utility model is related to a kind of heat supply butterfly valves, are specifically a kind of heat supply high temperature and pressure sealed butterfly valve.
Background technology
Butterfly valve is widely used in the multiple fields such as the construction of urban pipe network heating power, gas pipeline and urban pipe network.Butterfly valve can
For cutting off, throttling, the functions such as adjusting, the closing organ of butterfly valve is butterfly plate, is rotated in valve body around the axis of its own, so as to
Achieve the purpose that keying or adjusting.For heat supply butterfly valve, medium temperature is higher, and pressure ratio normal work during high-temperature steam aggregation
It is higher by much as pressure, all using simple graphite or PTFE seal, graphite energy high temperature resistant is suitble to the most of producers in filler part
Worst hot case, but under high-pressure situations, graphite does not have permanent service life.And PTFE is only used for room temperature, at high temperature
Without good sealing performance.How sealing performance and service life that high temperature and high pressure condition under heat supply butterfly valve permanent is ensured,
The direction studied as us.
Utility model content
The purpose of this utility model is to provide a kind of heat supply high temperature and pressure sealed butterfly valve, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical solution：
A kind of heat supply high temperature and pressure sealed butterfly valve including butterfly plate, trim ring, sealing ring, valve body, valve rod, axle sleeve, compound is filled out
Material, gland, sealing ring are pressed to by trim ring on butterfly plate, and sealing ring adulterates stainless steel wire using soft graphite, and valve rod runs through
Entire butterfly plate, the other end of valve rod connect executing agency, the gap filling axis between the outer surface of valve rod and valve body by stent
Set and compounded mix, the top of compounded mix set gland.
As further program of the utility model：Valve body, butterfly plate and sealing ring form the sealed body of entire valve.
As further program of the utility model：Compounded mix by set from bottom to top enhancing tetrafluoro, PEEK,
ELGILOY and graphite composition.
As further program of the utility model：Gland is secured by bolts on the top flange of valve body.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in structure, at low cost, is resistant to
High pressure, stabilization safe to use and convenient for large-scale production promote；The selection of each component material and the increase of compounded mix, can
Effectively improve the sealing performance and service life of butterfly valve.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Please refer to Fig.1~2, in the utility model embodiment, a kind of heat supply high temperature and pressure sealed butterfly valve, including butterfly plate 1,
Trim ring 2, sealing ring 3, valve body 4, valve rod 5, axle sleeve 6, compounded mix 7, gland 8, the sealing ring 3 are pressed to by trim ring 2
On butterfly plate 1, valve body, butterfly plate and sealing ring form the main body of entire butterfly valve seal, and sealing ring 3 adulterates stainless steel using soft graphite
Silk, guarantees to run under worst hot case, and valve rod 5 runs through entire butterfly plate 1, and the other end of valve rod connects execution machine by stent
Structure drives the rotation of butterfly plate 1 to realize the switching motion of valve by valve rod 5；
Gap filling axle sleeve 6 and compounded mix 7 between the outer surface of valve rod 5 and valve body 4, compounded mix is by from bottom to top
The enhancing tetrafluoro of setting, PEEK, ELGILOY and graphite composition, can bear 10000Psi pressure；
Gland 8 is set at the top of compounded mix 7, gland 8 is secured by bolts in the top flange of valve body 4
On, it is compacted by 8 compounded mix 7 of gland；
Compounded mix 7 is made of enhancing tetrafluoro, PEEK, ELGILOY and the graphite set from bottom to top so that compounded mix
The intensity of 7 existing metallic frameworks and PEEK enhancing compounded mixs, and there is enhancing tetrafluoro and graphite to improve the lubricity of compounded mix,
The friction of filler is reduced, PEEK has good sealing performance, can meet high-temperature steam band in maximum magnitude at high temperature under high pressure
The Flexible change come improves the service life of valve.
The standardized element that the utility model uses can commercially, shaped piece according to specification and attached drawing
Record can carry out customized, the specific connection mode of each part is using bolt ripe in the prior art, rivet, weldering
It connects and waits conventional means, machinery, part and equipment use in the prior art, conventional model, in addition circuit connection is using existing
Conventional connection mode in technology, this will not be detailed here.
