Abstract
The utility model belongs to the technical field of valve structure, specific saying so relates to a novel lining tetrafluoro structure valve, mainly is the structural style in order to provide a neotype tetrafluoro bush valve body for the valve body plays good sealed effect in high -risk corrosive medium's pipeline, do not have the technical risk of high -risk gas leakage moreover, provides a novel lining tetrafluoro structure valve, including the valve body, be provided with flange at the lower tip of valve body, valve body and flange pass through bolt fixed connection, all are provided with the tetrafluoro bush through two dovetail fixed connection inside flange and valve body, the utility model discloses structural design is simply applicable, and the inventive concept is unique novel for the valve body plays good sealed effect in high -risk corrosive medium's pipeline, do not have the technical risk of high -risk gas leakage moreover, thus the effectual harm that has prevented emergence severe accident.
Description
Technical field
This utility model belongs to valve mechanism technical field；Particularly relate to a kind of Novel tetrafluoro lined structure valve.
Background technology
The stop valve used currently on the market or check-valves are in the process used, usually there will be the structural design of liner and be connected untight technical problem with valve body structure, in process particularly in conveying deep-etching high-risk medium, the connection sealing of valve mechanism can be not, the risk factor that deep-etching high-risk medium is revealed can be produced, if processing not in time, then can produce to occur the great dangerous consequences of major accident, in using the valve body with tetrafluoro lining, tetrafluoro lining can not reach the good technical problem sealing off high-risk corrosive fluid.
Summary of the invention
Goal of the invention of the present utility model:
It is primarily to the version that a kind of novel tetrafluoro lining valve body is provided, valve body is made to play good sealing effectiveness in the pipeline of high-risk Korrosionsmedium, and be absent from the technical risk that high-risk gas leaks, thus it is effectively prevented the harm that major accident occurs.
The technical solution of the utility model is:
Provide a kind of Novel tetrafluoro lined structure valve, including valve body, the bottom of valve body is provided with adpting flange, valve body and adpting flange be bolted to connection, inside adpting flange and valve body, is provided with the tetrafluoro lining being fixed connection by double swallow tailed groove.
Described double swallow tailed groove structure adopts the version of large-scale dovetail groove set connection small dovetail groove, and small-sized dovetail groove is arranged on the inside of large-scale dovetail groove.
Described valve body and double swallow tailed groove structure integral casting forming.
The beneficial effects of the utility model are:
Greatly improve the sealing property of tetrafluoro lining valve body so that valve body plays good sealing effectiveness in the pipeline of high-risk Korrosionsmedium, and is absent from the technical risk that high-risk gas leaks, thus being effectively prevented the harm that major accident occurs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of double swallow tailed groove of the present utility model.
In figure；1 is valve body；2 is adpting flange；3 is bolt；4 is double swallow tailed groove；5 is tetrafluoro lining；6 is large-scale dovetail groove；7 is small-sized dovetail groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Fig. 1～2, provide a kind of Novel tetrafluoro lined structure valve, including valve body 1, the bottom of valve body is provided with adpting flange 2, valve body and adpting flange connect by bolt 3 is fixing, it is provided with by the fixing tetrafluoro lining 5 connected of double swallow tailed groove 4 inside adpting flange and valve body, described double swallow tailed groove structure adopts large-scale dovetail groove 6 to overlap the version of connection small dovetail groove 7, small-sized dovetail groove is arranged on the inside of large-scale dovetail groove, described valve body and double swallow tailed groove structure integral casting forming, this utility model structural design is simply applicable, inventive concept uniqueness is novel, it is arranged mainly by the structure of double-deck dovetail, the position that tetrafluoro liner directly contacts with hazardous medium fluid with valve body and adpting flange etc. is made to be connected the tightr of sealing, valve body is made to play good sealing effectiveness in the pipeline of high-risk Korrosionsmedium, and it is absent from the technical risk of high-risk gas leakage, thus being effectively prevented the harm that major accident occurs.
