Abstract
The utility model relates to a spring multifunctional pressure-limiting valve which belongs to a pressure cooker which belongs to a cooking vessel safety feature technology field. The main body of the spring multifunctional pressure-limiting valve comprises a pressure-limiting valve body, a spool, a screw cap, a spring, a sealing ring, a screw, a pressure keeping hole, primary and secondary discharge ports, and lower discharge ports, wherein the pressure-limiting valve body is a stepped cylinder hole which is small in the upper portion and big in the lower portion, and the spool is through the spring and is arranged in the pressure-limiting valve body. And through the interaction of the boiler and the spring and the cooperation of the discharge ports, the pressure in the boiler can be kept in a stable condition. The utility model has the advantages that the utility model combines the pressure-limiting valve, the discharge port and an anti-blocking into an integral body, and is simple and reasonable in structure, which means that the utility model can keep a pressure cooker in a stable pressure when being heated, and can automatically release the air to a zero pressure when being cooled. And at the same time, the utility model is safe in anti-blocking, convenient in installation, and easy in clearing.
Description
The utility model relates to the multi-functional pressure-limit valve of a kind of spring, belongs to cooking utensil pressure cooker technical field of safety devices.
The pressure-limit valve of pressure cooker, outlet pipe, Anti-stop cover mostly are three kinds of independent components greatly now, and cost of production is higher like this, complex structure, and installation is wasted time and energy.Simultaneously, cooling final vacuum pressure leak process also is difficult for pot inner pressure is reduced to zero fully.
The purpose of this utility model is to provide a kind of simple in structure, with low cost at the problem of above-mentioned existence, and collection pressure-limit valve, outlet pipe, Anti-stop cover are the multi-functional pressure-limit valve of spring of one.
The new purpose of this practicality is achieved through the following technical solutions:
It includes parts such as pressure limiting valve body, spool, nut, spring, seal ring, spiral shell nurse.In the middle of the pressure limiting valve body is big end down stepped shaft cylindrical hole, and the pressure-limit valve surface is provided with pressurize hole, following exhaust port, one-level exhaust port and secondary exhaust port.Described exhaust port down is 6, and the one-level exhaust port is 5, and the secondary exhaust port is 2.Spool is big end down stepped shaft cylinder axis, and it passes spring and is positioned in the pressure limiting valve body.Nut and spool upper end screw and place the pressure-limit valve external body.The cylindrical side of spool lower end is offered a groove, and the diameter of cylinder guarantees that greater than the last aperture of stepped shaft cylindrical hole spool does not break away from the pressure limiting valve body.Nut screws with the pressure limiting valve body lower end and links to each other, and the middle seal ring of placing is used for the sealing of pressure limiting valve body between pot cover.
The utility model has the advantages that: collection pressure-limit valve, outlet pipe, the anti-blocking one that covers in, simple and reasonable, can in heating process, make to keep pressure stable in the pressure cooker, in the time of can cooling off again, it is lost heart naturally be depressurized to zero.Simultaneously, safety is anti-blocking, easy for installation, cleaning is convenient.
Fig. 1 is a structural drawing of the present utility model.
Describe the utility model in detail below in conjunction with accompanying drawing:
The spring multifunctional safety valve is made up of nut 1, spool 2, pressure limiting valve body 3, spring 4, seal ring-5, nut 6, pressurize hole 9, following exhaust port 7, one-level exhaust port 10, secondary exhaust port 11 etc.After the pressure cooker heating, owing to produce pressure in the pot, spool 2 will drive spring 4 upwards motion in pressure limiting valve body 3 together, contact with pressure limiting valve body 3 upper ends until spring 4 upper ends, for pot inner pressure overcomes the process of spool 2 self gravitations, spring 4 is not compressed, and is idle stroke.In this process, the cool air in the pot will be discharged to outside the pot by pressurize hole 9 by upwards diffusion of the groove on the cylndrical surface, spool 2 lower end.
During normal the use, when pot inner pressure continuation rising, spool 2 stressed increases will drive spring 4 and continue to move upward.At this moment, spring 4 is compressed, and overcomes the process of spool 2 gravity and spring 4 elastic force for pot inner pressure.The user can observe the pressure of this moment in the pot according to the red-label of spool 2 upper ends.When spool 2 rises to its lower end and pressurize hole 9 lower end horizontal alignments, be the safety pressure of pressure cooker.If when pot inner pressure surpassed safety pressure, spool 2 lower ends rose to above 9 lower ends, pressurize hole stressed, at this moment, pressurize hole 9 exhaust pressure reliefs.Because pressure reduces, the stroke of spring 4 also will reduce.Therefore, elastic force overcomes pot inner pressure and will make spool 2 lower ends drop to position with pressurize hole 9 lower end horizontal alignments again.Motion and so forth, making its movement process is square tooth broken line.Therefore, pot inner pressure is in steady state all the time.
When fortuitous event occurring, go out because improper use pressurize hole 9 is stopped up or 9 exhausts of pressurize hole but pot inner pressure are still held and continued when raising, one-level exhaust port 10 or secondary exhaust port 11 will be crossed in spool 2 lower ends this moment, gas in the pot will outwards distribute by a plurality of exhaust ports simultaneously, reach the purpose of safety relief, then still repeat square profile of tooth motion recited above.
After the burning things which may cause a fire disaster of pressure cooker leaves, be in the state of cooling, the pressure in the pot reduces, and spool 2 drives spring 4 and moves downward, until initial position.At this moment, residual pressure will be by following exhaust port 7 in the pot, along the groove of spool 2 lower cylindrical faces through pressurize hole 9 and a plurality of I and II exhaust port 10,11 to external diffusion, be zero up to pot inner pressure.Following exhaust port 7 plays anti-blocking effect simultaneously, can prevent that the food fragment from entering pressure limiting valve body 3 inner pressurize hole 9 and the I and II exhaust ports 10,11 of stopping up.
