Abstract
The invention relates to the technical field of high-pressure cookers, for example, various pressure cookers, pressure cooker bodies, and the like used when people cook foods usually, of course, the technology can be widely applied to industrial high-pressure equipment, properly speaking, the invention relates to a multi-insurance pressure cooker which mainly comprises a pressure cooker body and a boiler cover. The multi-insurance pressure cooker is characterized in that the cooker cover is connected with two or more spring safety valves, exhaust valve covers connected with the cooker cover cover on the spring safety valves, wherein the spring safety valves are anti-explosion valves, exhaust valves and the spring safety valves are respectively connected with the cooker cover, the edge of the cooker cover is provided with an anti-explosion window, a handle of the cooker cover and a self-locking plate valve are connected to the cooker cover, the inner edge of the cooker cover is movably connected with a sealing rubber ring; and a cooker body handle corresponding to the handle of the cooker cover is connected above the pressure cooker body. Generally, the invention has the key point that the cooker cover of the pressure cooker is provided with the two or more safety valves, and in a practical use process, other safety valves can be replaced if some safety valve has a failure.
Description
Technical field:
The present invention relates to the pressure cooker body technical field of structures, as our the daily used various pressure cookers of boiled dinner thing, pressure cooker body or the like of boiling, present technique also can be widely used in the industrial high-tension apparatus certainly, and exactly the present invention is a kind of Pressure cooker with multiple safety functions.
Background technology:
At present pressure cooker has obtained using widely, and it is simple to operate, and is practical and liked by people, everybody pressure cooker of being familiar with for example, and it can stew the chop that we like eating mashed in a short period of time; Industrial boiler commonly used utilizes the pressure in the boiler can make steam be transported to far place.But the size of pressure is most important to safety.If there is not rational safeguard protection, the excessive accident that similar blast, poison gas leakage etc. will take place of pressure.In order to take precautions against the harm of pressure, people are needing to have designed a lot of automatic safety devices on the equipment of high pressure.
Present existing pressure cooker mostly mainly is to utilize steam vent and a valve to be used, and this valve designs for controlled pressure, i.e. deadweight safety valve.A weight is arranged on the safety valve, and it is pressed on the steam vent of pressure cooker at ordinary times, and the pressure in pressure cooker reaches certain force value, because the effect of pressure, weight is lifted.Steam is got rid of from steam vent, so that the pressure in the pressure cooker drops in the safety value scope, the pressure cooker structure of other structure is also similar, there is weak point in its structure, such as having only a safety valve, go wrong as this unique safety valve, then be easy to cause the generation of accident, so be necessary to research and develop in this respect.
Summary of the invention:
The objective of the invention is to: solve the weak point of traditional product, provide a kind of same pot body to be provided with a plurality of safety valves, to realize the pressure cooker that maltilevel security ensures.
The technical solution adopted for the present invention to solve the technical problems is: the present invention mainly forms by the pressure cooker body with pot cover, it is characterized in that: be connected with two and plural spring safety valve on the pot cover, the top of spring safety valve is covered with the exhaust valve cap that is connected with pot cover, here the spring safety valve of indication also is explosion-proof valve, air bleeding valve is connected with pot cover respectively with spring safety valve, the edge of pot cover offers explosion proof window, pot cover handle and self-locking plate valve are connected on the pot cover, and the pot cover edge activity is connected with O-ring seal; Described pressure cooker body top is connected with the pot skill handle with the pot cover handle correspondence.Main points generally of the present invention are to be provided with two or more safety valves on the pot cover of pressure cooker, in actual use, the cisco unity malfunction if some safety valves break down, then other safety valve then can replace, realize operate as normal, the minimizing accident takes place, thereby realizes purpose of the present invention.
The beneficial effect that the present invention produced: solve the weak point of traditional product, provide a kind of same pot body to be provided with a plurality of safety valves, to realize the pressure cooker that maltilevel security ensures.
Description of drawings:
Fig. 1 is wherein a kind of outward appearance simplified schematic diagram of version of the present invention.
Structural representation sketch when Fig. 2 removes air bleeding valve for pot cover of the present invention.
Among the figure: 1 expression pressure cooker body, 2 expression pot skill handles, 3 expression pot cover handles, 4 expression self-locking plate valves, 5 expression pot covers, 6 expression air bleeding valves, 7 expression O-ring seals, 8 expression explosion proof windows, 9 expression exhaust valve caps, 10 expression spring safety valves.
The specific embodiment:
The present invention can exist in a variety of forms, existing with a kind of form wherein in conjunction with the accompanying drawings.
Among the figure: 1 expression pressure cooker body, 2 expression pot skill handles, 3 expression pot cover handles, 4 expression self-locking plate valves, 5 expression pot covers, 6 expression air bleeding valves, 7 expression O-ring seals, 8 expression explosion proof windows, 9 expression exhaust valve caps, 10 expression spring safety valves.
The present invention mainly forms by pressure cooker body 1 with pot cover 5, as shown in the figure: be connected with two and plural spring safety valve 10 on the pot cover 5, the top of spring safety valve 10 is covered with the exhaust valve cap 9 that is connected with pot cover 5, here the spring safety valve of indication also is explosion-proof valve, air bleeding valve 6 is connected with pot cover 5 respectively with spring safety valve 10, the edge of pot cover 5 offers explosion proof window 8, and pot cover handle 3 and self-locking plate valve 4 are connected on the pot cover 5, and pot cover 5 edge activity are connected with O-ring seal 7; Described pressure cooker body 1 top is connected with the pot skill handle 2 with pot cover handle 3 correspondences.Main points generally of the present invention are to be provided with two or more safety valves on the pot cover of pressure cooker, in actual use, the cisco unity malfunction if some safety valves break down, then other safety valve then can replace, realize operate as normal, the minimizing accident takes place, thereby realizes purpose of the present invention.
The present invention can reach the maltilevel security guarantee fully, first and second heavy safety guarantee: if the pressure cooker pot cover correctly do not close, then pressure cooker can not pressurize, if pot inner pressure is during greater than 5Kpa, pot cover can not be opened auto lock; The triple safe guarantee is an air bleeding valve, adopts accurate spring pressure limiting structure, and normal to guarantee pot inner pressure, unnecessary steam can be discharged in steam vent; Fourth, fifth, six safety guarantee are safety valves, ad hoc triple spring safety valves, three times of safety; The septuple safety guarantee is an explosion proof window, and when all losing efficacy as if above-mentioned safety guarantee, O-ring seal can be extruded pressure release at explosion proof window automatically, guarantees user's safety, and can protect a pot body not to be damaged.
The present invention can effectively solve the weak point of traditional product, provides a kind of same pot body to be provided with a plurality of safety valves, to realize the pressure cooker that maltilevel security ensures.
