The invention is characterized in that the sheath cover is movably sheathed with the metal valve while the connection has groove arranged at the circumference; the groove is sheathed by a soft sheath ring. The invention has simple structure, low cost and high safety.
Description
Technical field
The present invention relates to the electric pressure cooking saucepan technical field of parts and components.
Background technology
Electric pressure cooking saucepan is more and more accepted by people because it is easy to use and energy-conservation, because electric pressure cooking saucepan belongs to pressure vessel, thereby the pressure-relief valve security of its use is the major issue that must solve.The relief valve of electric pressure cooker of prior art generally is to be movably set on the valve rod of pot cover surface, constitute by plastic cement upper shield and metal valve body, the fixedly sleeved metal valve body of plastic cement upper shield, valve body is a tubular, valve body both sides and upper shield junction have the plurality of rows pore, when pot inner pressure acquires a certain degree, the jack-up upper shield is with emission gases, reach the decompression purpose, though above-mentioned pressure-relief valve can play the release pressure stabilization function, in using many problems are arranged, be with food to enter in the valve body easily as gas, be not easy to cleaning, stop up steam vent easily; In addition plastic cement upper shield and metal valve body affixed because of service time for a long time, reasons such as unlike material and high-temperature steam, that upper shield is easy to generate is aging, come off, and has potential safety hazard.Adopt the structure that plastic tube is set in the metal valve body in addition, there are the problems referred to above equally in it.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of simple in structure, safe and reliable relief valve of electric pressure cooker for the deficiency that solves prior art.
The technical solution that the present invention adopts in order to achieve the above object is as follows:
This relief valve of electric pressure cooker, be set on the valve rod, comprise upper shield and metal valve body, upper shield is connected with metal valve body, upper shield and metal valve body top all are provided with steam vent, it is characterized in that described upper shield and metal valve body socket, fluted and the software collar of the metal valve body outer periphery of metal valve body and upper shield junction, the described software collar is set on the groove.
Described groove is one or several.
As further specifying of such scheme, described groove is provided with two, and corresponding recesses is arranged with the software collar outward, and this software collar face is the conical surface.
Described metal valve body top center position has groove, is provided with taper in the middle of the valve inner under the groove and weighs down.
Described steam vent is six, evenly is provided with at interval.
The upper shield bottom of described socket metal valve body is a heaving of the sea shape structure, and the upper shield upper end also is provided with dead man.
The bottom inner face of described metal valve body also has groove, is provided with the elasticity steel spring in the groove, and withhold together elasticity steel spring and valve rod end.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, by on metal valve body, slotting, put the software collar again, with the upper shield socket, production and processing is simple, and for convenience detach cleaning the, and good airproof performance are safe.
2, the present invention improves on existing pressure-relief valve basis and forms, and is simple in structure, effective, is applicable to all pressure cookers, and excellent generalization values is arranged.

The specific embodiment
By Fig. 1, shown in Figure 2, this relief valve of electric pressure cooker, be on existing pressure-relief valve basis, to improve to form, be set on the valve rod 6, it comprises upper shield 1 and metal valve body 2, upper shield 1 and metal valve body 2 sockets, upper shield 1 all is provided with steam vent 3 with metal valve body 2 tops, and steam vent 3 is six evenly equal circumference settings at interval.The cover tubular of the end opening that this upper shield 1 is made for plastic cement, steam vent is located at the other end, upper end exhaust nose end periphery is provided with driving lever 7, openend is heaving of the sea bottom 8, it and metal valve body 2 pivot bush units, metal valve body 2 has two grooves 4 with the periphery of upper shield 1 junction, and this groove is arranged with the software collar 5 outward, these software collar 5 surfaces are the conical surface, to adapt to the fastening needs of socket; Described metal valve body 2 top center positions have groove, are provided with taper in the middle of the valve inner under the groove and weigh down; The bottom inner face of metal valve body 2 also has groove, is provided with elasticity steel spring 9 in the groove, and elasticity steel spring 9 is withheld together with the valve rod end.
When using, the pot internal gas pressure surpasses when setting, upper shield and valve body rotate, and the set strong point that is equipped with joins on least significant end that the upper shield bottom rises and falls and the valve body, separates with pot cover upper valve rod discharge duct, reach the decompression purpose, under normal condition, metal valve body is owing to its gravity effect, and the set strong point that is equipped with joins on most significant end that the upper shield bottom rises and falls and the valve body, be tightly connected with the valve rod discharge duct, safe and reliable; And upper shield and valve body can guarantee the fixing of the two by the software collar, good airproof performance, and when the needs disassembly, cleaning, also very convenient operation.
