Model utility content
Based on this, be necessary for the deficiencies in the prior art, a kind of anti-explosion safety Decompression valves of quick release pressure when there is the pressure jump that tempering, blast or other factors cause in combustion gas explosive motor air inlet pipeline is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of anti-explosion safety Decompression valves, it comprises valve seat and upper cover plate that center is provided with pressure relief opening, described valve seat is fixedly connected with by bolts and nuts with upper cover plate, formation cavity volume is enclosed between described valve seat and upper cover plate, be provided with the sealing plate that pressure relief opening can be sealed in described cavity volume, be provided with locating stud between described sealing plate and upper cover plate, outside described locating stud, be arranged with spring.
Wherein in an embodiment, described spring side is installed on fire extinguishing fin, and described fire extinguishing fin is communicated with pressure relief opening.
Wherein in an embodiment, above described sealing plate, laminating is provided with pad, and described spring is arranged on above described pad.
Wherein in an embodiment, described spring is disc spring structure.
Wherein in an embodiment, described valve seat and upper cover plate are flat structure.
Wherein in an embodiment, described valve seat is provided with containing groove in all sides of pressure relief opening, holds and be provided with seal ring in described containing groove.
Wherein in an embodiment, described containing groove is dovetail groove structure.
In sum, the utility model anti-explosion safety Decompression valves is by arranging sealing plate at pressure relief opening, coordinate spring to exert pressure to sealing plate pressure relief opening sealed, when pressure in air inlet pipeline is elevated to cracking pressure, spring reduce to sealing plate force effect, make to fire mixed gas and outwards drain from pressure relief opening; Utilize the cooling effect of fire extinguishing fin simultaneously, make the temperature of burnt gas be reduced to below burning-point, and then play fire extinguishing function, avoid producing naked light and the danger of blasting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model anti-explosion safety Decompression valves;
Fig. 2 is the half sectional view of the utility model anti-explosion safety Decompression valves.
Embodiment
For feature of the present utility model, technological means and the specific purposes reached, function can be understood further, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model anti-explosion safety Decompression valves comprises valve seat 10 and the upper cover plate 20 that center is provided with pressure relief opening 11, and described valve seat 10 is fixedly connected with nut 13 by bolt 12 with upper cover plate 20, and described valve seat 10 and upper cover plate 20 are flat structure.
Enclose between described valve seat 10 and upper cover plate 20 and form cavity volume 14, the sealing plate 30 that pressure relief opening 11 can be sealed is provided with in described cavity volume 14, locating stud 40 is provided with between described sealing plate 30 and upper cover plate 20, spring 50 is arranged with outside described locating stud 40, elastic force is passed to sealing plate 30 by spring 50, makes it block pressure relief opening 11; Described locating stud 40 pairs of springs 50 carry out spacing, and to avoid product when having an effect, spring 50 is shifted the phenomenon causing anti-explosion safety Decompression valves malfunctioning.
Particularly, described spring 50 is disc spring structure, to ensure that spring 50 can not cause the situation that cannot reset because of overvoltage, and then maintain the stable of cracking pressure, meanwhile, adopt disc spring structure requisite space little, combinationally use conveniently, maintenance changes the outfit easily, and economy and security is high.
Described valve seat 10 is provided with containing groove in pressure relief opening 11 weeks sides, holds and be provided with seal ring 60 in described containing groove, to ensure that combustion gas can not be leaked; Particularly, described containing groove is dovetail groove structure, and to ensure the sealing of product when normally working, effectively prevent the utility model when opening pressure release, O RunddichtringO 60 is not blown out by pressurized gas and loses seal action.
Wherein in an embodiment, above described sealing plate 30, laminating is provided with pad, and described spring 50 is arranged on above described pad, by regulating described pad, carrys out the elastic force of Regulation spring 50, and then reaches the object regulating and preset pressure release power.
Wherein in an embodiment, described spring 50 side is installed on fire extinguishing fin 70, described fire extinguishing fin 70 is communicated with pressure relief opening 11, described fire extinguishing fin 70 is in order to carry out contacting and lowering the temperature to it with burnt gas, make its temperature drop to below burning-point, and then realize the fire extinguishing function to burnt gas.
When the utility model specifically uses in the air inlet pipeline of combustion gas explosive motor, if combustion gas explosive motor generation tempering fault, pressure in air inlet pipeline raises instantaneously, inflammable gas due to air inlet pipeline is the mixed gas of combustion gas and air, run into naked light to blast in the cavity volume 14 of sealing, when explosion pressure reaches the cracking pressure that product presets time, high pressure air knows from experience promotion butterfly spring upwards, decompression protection is carried out to the burnt gas of air inlet pipeline simultaneously, thus ensure the safety of unit equipment and personnel; In addition, the gas fired contacts with fire extinguishing fin 70 when outwards draining, and the heat that fire extinguishing fin 70 pairs of burnt gas produce dispels the heat, and makes the temperature of burnt gas drop to below burning-point, and then play fire extinguishing function, avoid producing naked light and the danger of blasting.
In sum, the utility model anti-explosion safety Decompression valves is by arranging sealing plate 30 at pressure relief opening 11, coordinate spring 50 pairs of sealing plates 30 to exert pressure pressure relief opening 11 sealed, when pressure in air inlet pipeline is elevated to cracking pressure, spring 50 reduces the force effect to sealing plate 30, makes to fire mixed gas and outwards drains from pressure relief opening 11; Utilize the cooling effect of fire extinguishing fin 70 simultaneously, make the temperature of burnt gas be reduced to below burning-point, and then play fire extinguishing function, avoid producing naked light and the danger of blasting.
The above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with claims.
