Abstract
The invention discloses a pressure relief device which comprises a disk-shaped shell. The inner side wall of the top of the shell is provided with a ring-shaped groove; the shell is also provided with an air relief hole communicated with the ring-shaped groove; the inside of the ring-shaped groove is connected with a baffle by a spring; the diameter of the baffle is between the inner diameter and the outer diameter of the ring-shaped groove; and the thickness of the baffle is less than the width of the ring-shaped groove. The pressure relief device disclosed by the invention has a simple structure and is convenient to use; and as the gap between the ring-shaped groove in the shell and the baffle is regulated by the pressure applied to the baffle by the air pressure, the gravity of the baffle and the elastic pressure applied to the baffle by the spring according, not only the requirement on pressure relief can be effectively met, but also the effect of automatically regulating the pressure can be implemented and production development of enterprises is promoted.
Description
Technical field
The present invention relates to a kind of pressure relief device, be specifically related to pressure relief device a kind of simple in structure, easy to use.
Background technique
Employed pressure relief device complex structure is made cost higher in the market, wherein uses in some to the pressure release requirement are not very strict equipment, it can cause and structure unnecessary, with the residue of function, the user cost that this can increase equipment, be unfavorable for the production development of enterprise.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed pressure relief device simple in structure, easy to use.
Technical solution of the present invention is achieved in that a kind of pressure relief device, comprises discoidal housing, and described housing has annular groove at the madial wall at its top; Also be provided with the bleeder port that is communicated with annular groove on the described housing; Is connected with baffle plate by spring in the described annular groove, and the diameter of described baffle plate is between the inner diameter and outer diameter of annular groove, the thickness of baffle plate is less than the width of annular groove.
Further, the position at described bleeder port place is arranged on the madial wall near annular groove.
Further, described baffle plate is made by elastic material.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described pressure relief device of the present invention program is simple in structure, easy to use, in the process of using, the pressure that gas in housing forms baffle effect is greater than the self gravitation of baffle plate, and spring is during to its elastic pressure, gas in the housing will be baffle plate jack-up up, at this moment the gas in the housing just can flow to bleeder port from the gap between baffle plate and the annular groove, then run out of from bleeder port, and then reach the purpose of pressure release, because the annular groove in the housing and the gap between the baffle plate are by air pressure the pressure of baffle plate and baffle plate self gravitation and spring to be regulated its elastic pressure, so just can automatically reach according to demand the requirement of pressure release, not only can effectively satisfy the pressure release requirement, and can realize the effect of automatic Regulation, promote enterprise in production development.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the sectional view of pressure relief device of the present invention when closing pressure condition;
Accompanying drawing 2 is the sectional view of pressure relief device of the present invention when the pressure release state;
Wherein: 1, housing; 2, annular groove; 3, bleeder port; 4, spring; 5, baffle plate.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1,2 is a kind of pressure relief device of the present invention, comprises discoidal housing 1, and the madial wall of described housing 1 at its top has annular groove 2; Also be provided with the bleeder port 3 that is communicated with annular groove 2 on the described housing 1; Be connected with baffle plate 5 by spring 4 in the described annular groove 2, and the diameter of described baffle plate 5 is between the inner diameter and outer diameter of annular groove 2, the thickness of baffle plate 5 is less than the width of annular groove 2.
Pressure relief device of the present invention is simple in structure, easy to use, in the process of using, when the pressure that effect forms to baffle plate 5 of the gas in the housing 1 greater than the self gravitation of baffle plate 5 and spring 4 during to its elastic pressure, gas in the housing 1 will be baffle plate 5 jack-up up, at this moment the gas in the housing just can flow to bleeder port from the gap between baffle plate 5 and the annular groove 2, then runs out of from bleeder port 3, and then reaches the purpose of pressure release; When the gas pressure that effect forms to baffle plate 5 less than the self gravitation of baffle plate 5 and spring 4 during to its elastic pressure, baffle plate 5 is under the effect of the elastic pressure of self gravitation and spring 4, drop on down on the annular groove 2 of housing 1, and then formation is to the seal action of housing.Because the annular groove 2 in the housing 1 and the gap between the baffle plate 5 are by air pressure the pressure of baffle plate 5 and baffle plate 5 self gravitations and spring 4 to be regulated its elastic pressure, so just can automatically reach according to demand pressure release, close the requirement of pressure; Not only can effectively satisfy the pressure release requirement, and can realize the effect of automatic Regulation, promote enterprise in production development.
The position at wherein said bleeder port 3 places is arranged on the madial wall near annular groove 2, is conducive to like this pressure relief device in the process of pressure release, and the gas in its housing 1 is run out of from bleeder port 3; Described baffle plate 5 is made by elastic material, has made things convenient for like this gas in the housing to the top pressure effect of baffle plate 5, and jack-up part baffle plate 5 carries out as requested, gas communication, and then reach the function of pressure release.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
