Abstract
The utility model relates to the exhaust valve of a pressure cooker, which is composed of a valve seat and a valve core. The valve seat is stamped out on a cooker cover, the valve core matching the valve seat is made from a steel ball, one end of a spring sheet welded with the valve core is fixed on the outer wall of the pressure cooker cover, a supporter is arranged between the fixed point of the cooker cover and the welding position of the valve core and the spring sheet, a screw hole is arranged on the supporter, a screw penetrates the screw hole and presses the spring sheet, a fulcrum arranged on the cooker cover is connected with a lever which can flexibly rotate, and one end of the lever is a key-press. The utility model has the advantages of simple structure, adjustable pressure, durability, etc., and moreover, the utility model does not easily scald hands.
Description
Technical field
The utility model relates to a kind of air bleeding valve of pressure cooker.
Background technology
No. 95229568.7, Chinese patent, name is called: the utility model of " a kind of anti-blocking pressure-adjusting type pressure cooker air bleeding valve ", a kind of anti-blocking pressure-adjusting type pressure cooker air bleeding valve is disclosed, this air bleeding valve is stifled by end capped pipe, outer tube, valve, spring, spring pressure cap and draw ring constitute, this utility model can prevent that larger particles from stopping up steam vent, can discharge along hole wall than granule, and can regulate pot inner pressure as required easily, the stifled phenomenon of losing of valve can not take place.But this utility model, is scalded hand when taking draw ring the mode of the stifled pull-up of valve easily with stay cord, and, come the stifled pressure of control valve to regulate pot inner pressure with spring pressure cap pressing spring, the structure more complicated, spring gets rusty easily and lost efficacy.
The utility model content
The utility model is in order to overcome the deficiency that above-mentioned prior art exists, a kind of adjustable in pressure to be provided, be not easy to scald one's hand, and simple in structure, reliable pressure cooker control valve.
In order to solve the problems of the technologies described above, the air bleeding valve of a kind of pressure cooker of the utility model is made of valve seat and spool, and this valve seat is that the punching stretching forms a funnel-shaped apertures on high-pressure pot cover, spool clogs valve seat, and an end of a spring leaf is pushed down spool, the other end is fixed on the pot cover.
This spool is formed by a steel ball, and is stuck in the valve seat just and clogs valve seat, and spool and spring leaf weld together, and spring leaf fixedly steel ball place is provided with a shrinkage pool, and shrinkage pool and steel ball are suitable and wrap up 1/4th steel balls;
Also be provided with a support between the pot cover fixing point of spring leaf and spool, support is provided with a screw, and a screw passes the screw roof pressure on spring leaf.
Also be provided with a lever at support by spool one side, an end of lever acts on the spring leaf, and the other end is provided with button.The fulcrum of this lever is arranged on the pot cover, or is arranged on the support.
The utility model compared with prior art has following advantage: 1, the utility model can be regulated the interior pressure of pot by the turn-knob screw as required, and is very convenient; 2, the phenomenon with the hand scald can not take place in the utility model when regulating pot inner pressure, and is fool proof; 3 the utility model need only push button and just can reach the purpose of exhaust, and are safe and convenient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Shown in figure one, the utility model is a kind of air bleeding valve of pressure cooker, it is by valve seat 7, spool 5, spring leaf 4 constitutes, this valve seat 7 is through punching on the pot cover 1 of pressure cooker, punching stretch forms a funnelform through hole again, spool 5 is made of a steel ball, and be stuck in just in the valve seat 7, spool 5 welds together with spring leaf 4, one end of spring leaf 4 is fixed on the outer wall of pot cover 1, spring leaf 4 fixed spools 5 steel ball places are provided with a shrinkage pool, shrinkage pool and steel ball are suitable and wrap up 1/4th steel balls, between pot cover 1 fixing point and spool 5 and spring leaf 4 welds a support 3 are arranged, and support 3 is provided with a screw, screw 2 passes the screw roof pressure on spring leaf 4, screw by screw 2 turn-knobs, give spring leaf 4 big more to the power that presses down, the pressure in the pressure cooker also becomes big, otherwise, screw 2 turn-knobs revolve loosely, give spring leaf 4 just little to the power that presses down, and the pressure in the pressure cooker is also diminished.One fulcrum 8 is arranged on the high-pressure pot cover 1, and this fulcrum 8 links together with lever 6, and lever 6 can rotate flexibly, one end of lever 6 is a button, pushes button, and the other end of lever 6 is upturned, and spring leaf 4 is upwards propped, and spool 5 has just left valve seat 7, has also just opened steam vent.
When needs were regulated pot inner pressure, turn-knob screw 2 can achieve the goal, and during exhaust, the pressing plate that need only press on the lever 6 gets final product.
