Abstract

The utility model relates to an explosion-proof exhaust valve for a household pressure cooker. The utility model is structurally characterized in that the inside of a cover-typed weight dropper of the exhaust valve is provided with a valve needle which penetrates through an inner hole of an exhaust pipe and appears outside the exhaust pipe along an axial lead. Because the valve needle can have the blocking function, and the clogging objects can not easily clog the exhaust pipe, the explosion-proof function is achieved, which effectively overcomes the defect of prior art. The utility model, which has the advantages of simple structure, low manufacturing cost and convenient operation, is suitable for various cooking pressure cookers.

Description

Anti-explode exhause valve for pressure cooker of household

The utility model relates to a kind of pressure vessel explosion-protection equipment, particularly a kind of family expenses pressure cooker anti-explosion exhaust valve.

As everyone knows, the family expenses pressure cooker is one of cooking cook ware of using always of people.For pot inner pressure is increased, adopt a kind of air bleeding valve usually with weight, the bell-type weight on blast pipe is constituted by blast pipe that is arranged at the pot cover top and pivot bush unit.During use, when pot inner pressure is elevated to certain value, gas pressure is discharged jack-up bell-type weight outside the pot, can prevent pressure cooker pressure superelevation and sets off an explosion.Yet, in use, the time have explosion accident to take place, trace it to its cause, blast pipe is received some materials (as skin of beancurd, particle food etc.) and is stopped up caused often.For addressing this problem, prior art often adopts a thermosol formula easing valve, have some pressure cookers also to set up a differential pressure type easing valve on this basis and realize dual fail-safe, but weak point is to have increased cost, and make troubles to user's use.

The purpose of this utility model is to overcome the prior art deficiency, and a kind of simple in structure, family expenses pressure cooker anti-explosion exhaust valve that again can be explosion-proof is provided.

Task of the present utility model realizes by this way: as shown in Figure 1, this anti-explosion exhaust valve includes blast pipe (2) and bell-type weight (1), but done following improvement, be provided with one at bell-type weight (1) endoporus center along axial line and pass blast pipe (2) endoporus and expose to needle (3) outside the blast pipe (2).

Fig. 1 is a longitudinal sectional view of the present utility model.

The utility model is like this work: the same with prior art, be installed on the pot cover, after pot inner pressure surpasses certain value, in the pot gas just along the gap of needle (3) and blast pipe (2) endoporus up jack-up bell-type weight discharge outside the pot.Owing to be provided with needle (3), and needle (3) protrudes outside the blast pipe (2), showy or unexpected material near blast pipe (2) often is hampered by needle (3) and is difficult to stop up blast pipe (2), also can't stop up whole air inlet even stop up one one.Therefore, the utility model can prevent blast pipe (2) clogging effectively, avoids explosion accident to take place.In addition, simple in structure in addition, advantage that the system valency is low, easy to use.When implementing the utility model, the length of needle (3) is suitable, too small inoperative to expose to (2) 3～10 millimeters of blast pipes, long DeGrain.The utility model is fit to various families pressure cooker to be adopted, and also can be used for similar pressure vessel and makes explosion-protection equipment.

Claims

1, a kind of family expenses pressure cooker anti-explosion exhaust valve includes blast pipe (2) and bell-type weight (1), it is characterized in that being provided with along axial line at bell-type weight (1) endoporus center one and passes blast pipe (2) endoporus and expose to needle (3) outside the blast pipe (2).

2, air bleeding valve according to claim 1, the length that it is characterized in that needle (3) is to expose to (2) 3～10 millimeters of blast pipes for well.
