Abstract
The utility model belongs to an improvement of a domestic safety valve for a pressure cooker, which comprises a rubber plug body, a positioning flange, and a sealing sheet, wherein, the rubber plug body is arranged at a cooker cover; the positioning flange and the sealing sheet are connected with the rubber plug body. The utility model is characterized in that the sealing sheet is provided with rupturing grooves; a point of the cooker cover corresponding to the position of the sealing sheet is provided with a pressure releasing hole. When the utility model is in use, if gas pressure in the cooker exceeds rated pressure, the sealing sheet is pushed into a bow back shape, the pressure releasing hole is exposed out to release gas in the cooker; if gas pressure in the cooker continuously rises, the plug body can be pushed out of the cooker cover to release gas; therefore, the pressure cooker is ensured to operate safely. The utility model has the advantages of low cost, convenient installation, high safety coefficient, etc. The utility model is suitable for being installed on an ordinary pressure cooker.
Description
The utility model relates to the accessory of family expenses pressure cooker, particularly to having a kind of improvement of safety valve on the pressure cooker now.
The safeties of existing pressure cooker have two kinds, and a kind of is fuse sheet, and another kind is a safety valve, and the former is malfunctioning easily, does not often have the safety guarantee effect; Latter's production process is loaded down with trivial details, complex structure, cost height.
It is a kind of simple in structure that the purpose of the utility model is to provide, and cost is low, pressure cooker flame-arrester vent plug that safety coefficient is high and corresponding pot cover thereof.
The pressure cooker flame-arrester vent plug comprises the rubber cock body that is contained on the pot cover, and cock body has had the flange of position-limiting action outside pot cover, and the cock body lower end is connected with diaphragm seal, and diaphragm seal has breaking groove on the surface of cock body outer wall correspondence.
With the corresponding pressure cooker lid of flame-arrester vent plug, have the consent that matches with cock body on it, pot cover has the camber line relief hole in corresponding to the diaphragm seal marginal position.
When the assembling of flame-arrester vent plug of the present utility model and pot cover was used, along with the rising of pot internal gas pressure, the diaphragm seal of flame-arrester vent plug will be pushed up into hunchbacked shape by air pressure gradually, and drive the diaphragm seal edge in intracardiac moving; Surpass specified air pressure if the pot internal gas pressure rises, the diaphragm seal that is hunchbacked shape will make relief hole expose, and at this moment, gas is by the outside exhaust of relief hole in the pot; If relief hole is blocked or other reason, when pot inner pressure continued to raise, cock body disconnected at breaking groove place and diaphragm seal, and is ejected pot cover under the effect of pressure, and at this moment, pot inner pressure reaches the purpose of security insurance by consent exhaust step-down.
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
State diagram when Fig. 2 is the utility model use.
Fig. 3 is a vertical view of the present utility model.
Referring to Fig. 1, the cock body 4 of pressure cooker flame-arrester vent plug is the garden tubular, cock body 4 top outer rims have had the circle protruding 5 of position-limiting action, cock body 4 bottoms are connected with diaphragm seal 6, diaphragm seal 6 and cock body 4 concentric gardens, diaphragm seal 6 has the V-shaped cast breaking groove 3 in cross section on the corresponding inner surface of 4 of cock bodys circle, the purpose of breaking groove 3 be for cock body 4 under certain effect, disconnect with diaphragm seal 6.Whole flame-arrester vent plug adopts silicon rubber one time punching molded.
Be shaped on the consent that matches with cock body 4 on the pressure cooker lid 2, around consent, have three equally distributed camber line relief holes 1, relief hole 1 can be for more than 4 or 4, its shape can form or other geometry for the hole, garden, but all in same garden on week, institute formation garden week diameter makes diaphragm seal 6 can seal relief hole 1 under the pressure cooker normal pressure less than diaphragm seal 6 diameters.
When the assembling of pressure cooker flame-arrester vent plug and pot cover was used, along with the rising of pot internal gas pressure, diaphragm seal 6 was become hunchbacked shape by roof pressure, if the over proof safe air pressure of pot inner pressure lets out that sheet packing 6 will be exposed in hole 1 and Fig. 2 is seen in pressure release; If this moment, the pressure cooker internal gas pressure continued to rise, cock body 4 will separate with diaphragm seal 6 fractures, is ejected pot cover 2 simultaneously, and overvoltage gas is discharged from pot cover 2 consents, so can avoid the generation of accident.
Obviously, the utility model is used again silicon rubber owing to adopt Double-insurance structure One time punching molded, so have the safety coefficient height, the advantage such as cost is low, and is easy for installation, Be suitable for being assemblied on family's pressure cooker of various models.
