Abstract
A kind of pressure cooker explosion relief valve, comprise that the middle part is provided with valve body (1), compression spring (3), sealing ring (2), connecting rod (4), pressure pointer (7) and the pressure scale plate (6) of steam vent (9), it is characterized in that: compression spring (3) upper end peaks at the safety valve top, the lower end peaks at sealing ring (2), sealing ring (2) is affixed with connecting rod (4) lower end, connecting rod (4) passes valve body (1) upper connecting rod hole, fixedlys connected with the pressure pointer (7) of pressure scale plate (6) side by side connecting rod (5) in its top.The utility model can be seen the pressure condition in the pressure cooker at any time, and its structure is simpler, and production cost is lower, and is easy to use, is easy to promote.
Description
Technical field
The utility model relates to a kind of safety valve, particularly a kind of pressure cooker explosion relief valve.
Background technology
The pressure of the pressure cooker of people's use now generally is to adjust with pressure valve, when pressure cooker is cooked product, pressure in the pot increases gradually along with the rising of temperature, when the pressure in the pot is increased to weight greater than pressure valve, steam in the pot has raised pressure valve, steam is discharged, and pot inner pressure reduces, and makes the pressure in the pot obtain adjusting.Also be provided with safety valve on the existing simultaneously pressure cooker cover, when pressure valve can't be worked, the kettle temperature rising just can be melted sheet to safety valve and be broken through the back steam discharge, prevents the pressure cooker blast.But the user can't know the pressure condition in the pot all the time, and when pressure valve opening and safe valve opening were all blocked, the steam in the pot can not be got rid of, continuing intensification can make the pressure in the pot increase, so just be prone to accidents, even the pressure cooker blast occurs, cause life security and property loss.For addressing the above problem, people have carried out a large amount of research work in this respect, as Chinese patent 87213496 disclosed pressure cooker temperature indicated pressure valves, replace safety valve with temperature indication pressure regulator valve, this temperature indication pressure regulator valve is combined with pressure regulator valve by the temperature indication mechanism and forms, it can test the temperature in the pressure cooker, be presented on the temperature indicating dial, be convenient to people and observe kettle temperature, still, this invention still can not solve the safety problem of the pressure cooker that people are concerned about most, above-mentioned potential safety hazard can appear equally, and complex structure, the pressure cooker production cost will obviously improve, and be difficult for promoting.
The utility model content
The purpose of this utility model is to overcome the prior art deficiency, provides a kind of easy to use, and production cost is low, can see the pressure cooker explosion relief valve of pot inner pressure at any time.The utility model comprises that the middle part is provided with valve body, compression spring, sealing ring, connecting rod, pressure pointer and the pressure scale plate of steam vent, the compression spring upper end peaks at the safety valve top, the lower end peaks at sealing ring, sealing ring and connecting rod lower end are affixed, connecting rod passes connecting rod hole, valve body top, fixedlys connected with the pressure pointer of pressure scale plate side by the side connecting rod in its top.
The steam vent that the valve body middle part is provided with is 1-4.
Described sealing ring is to stud with a heat-resistant film between two aluminium flakes or the copper sheet.
The utility model compared with prior art has following advantage:
1. can see the pressure condition in the pressure cooker at any time, make people's ground working pressure pot of feeling more relieved;
2. when the pressure in the pot reached certain index, sealing ring rose to more than the steam vent, and exhaust hole is with exhaust steam, and the pressure in the pot obtains adjusting, and makes pressure cooker safer;
3. because structure is simpler, and production cost is lower, be easy to promote;
Identical when 4. using, easy to use with existing pressure cooker;
Description of drawings
Fig. 1 analyses and observe diagrammatic sketch for the utility model structure.
The specific embodiment
As shown in Figure 1, the utility model comprises the valve body 1 of middle part band steam vent 9, valve body lower portion is provided with screw thread so that fixedly connected with high-pressure pot cover by nut, can set up a seal washer in case of necessity, the valve body top is provided with tie rod holes, be provided with compression spring 3 in the valve body, its upper end withstands on the pressure regulator valve top, the lower end withstands on the aluminium flake or copper sheet of sealing ring 2 moving up and down, compression spring is around in connecting rod 4, connecting rod 4 lower ends and sealing ring 2 are affixed, the upper end is passed valve body connecting rod hole and is fixedlyed connected with the pressure pointer 7 of pressure scale plate 6 sides by side connecting rod 5, sealing ring 2 is made of heat-resistant adhesive of edge between two aluminium flakes or the copper sheet, with prevent normal working pressure cook in steam discharge.The pressure scale plate indicates pressure scale: 40-250Kpa, and the pressure scale plate is outer in case of necessity can have additional a transparent material panel 8, and pressure scale plate scale is 20,100,150,200,250Kpa.When pressure cooker is cooked product, pressure in pot is greater than 40Kpa, sealing ring 2 promotes to move on the compression spring 3, promote connecting rod and drive 7 risings of pressure pointer, on corresponding pressure scale plate, show the pressure in the pot, when the pressure in the pot is increased to 250Kpa, 2 exhaust holes in explosion relief valve middle part are got rid of steam, and (the steam vent number increases as required or reduces certainly, be generally 1-4), pot inner pressure reduces, and the pressure in the pot obtains adjusting.
Claims (3)
1, a kind of pressure cooker explosion relief valve, comprise that the middle part is provided with valve body (1), compression spring (3), sealing ring (2), connecting rod (4), pressure pointer (7) and the pressure scale plate (6) of steam vent (9), it is characterized in that: compression spring (3) upper end peaks at the safety valve top, the lower end peaks at sealing ring (2), sealing ring (2) is affixed with connecting rod (4) lower end, connecting rod (4) passes connecting rod hole, valve body (1) top, fixedlys connected with the pressure pointer (7) of pressure scale plate (6) side by side connecting rod (5) in its top.
