Abstract
The utility model relates to the technical field of a pressure cooker, in particular to a high-efficiency practical pressure limiting valve of a pressure cooker. Compared with the prior art, the pressure limiting valve of the pressure cooker comprises a valve body, wherein the middle of the valve body is provided with a vent hole; an inverted-cone pressure valve core is pressed on the top end of the vent hole; a pressure seal sleeve is externally sheathed on the inverted-cone pressure valve core; a counterweight gland is pressed on the tail end of the inverted-cone pressure valve core; a through hole is formed in the counterweight gland. According to the pressure limiting valve, the counterweight gland cooperates with a travel counterweight block; the pressure is limited by using the self-gravity of the counterweight gland and the travel counterweight block; when the valve is at work, potential safety hazards caused by the ineffectiveness of original parts are unlikely to occur; moreover, the pressure control is constant without deviation; the valve has the advantages of stable pressure, safe use, simple structure and the like, thereby having a good market prospect.
Description
Technical field
The present invention relates to pressure cooker technical field, particularly a kind of efficient, practical limiting valve of pressure cooker.
Background technology
Limiting valve of pressure cooker of the prior art all adopts spring to withstand spool to carry out controlled pressure, because spring is repeatedly easily losing spring force or weakening elastic force in motion, therefore pressure limiting valve in use, its pressure can change along with the force variation of spring, after using certain fatigue limit, the elastic force meeting ultimate failure of spring, so pressure limiting valve also finally can lose pressure-limiting function.
Summary of the invention
For solving the existing defect of limiting valve of pressure cooker and problem in prior art, provide a kind of efficient, practical limiting valve of pressure cooker.
The present invention is that the technical scheme that its technical problem of solution adopts is: limiting valve of pressure cooker of the present invention comprises a valve body, in the middle of valve body, it is passage, on the top of passage, press a back taper pressure valve core, at described back taper pressure valve core overcoat one wiper seal cover, it is characterized in that, at described back taper pressure valve core tail end, press a counterweight gland, on described counterweight gland, have through hole.
Described valve body is provided with a gear shaft in outlet side.
On described counterweight gland, establish a link slot, on link slot, connect one stroke balancing weight.
Described stroke balancing weight matches with valve body, and is pressed in described gear shaft lower end.
The invention has the beneficial effects as follows: compared with prior art, limiting valve of pressure cooker of the present invention adopts the cooperation of counterweight gland and stroke balancing weight, utilize the self gravitation of counterweight gland and stroke balancing weight to carry out pressure limiting, when work, be difficult for the inefficacy of original paper occurs and produce potential safety hazard, and pressure is controlled constant zero deflection, there is pressure stability, use safety, advantages of simple structure and simple, there are good market prospects.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, limiting valve of pressure cooker of the present invention is described further.
Fig. 1 is the cross-sectional view of limiting valve of pressure cooker of the present invention.
The specific embodiment
As shown in Figure 1, limiting valve of pressure cooker of the present invention comprises a valve body 10, in the middle of valve body 10, it is passage 11, on the top of passage 11, press a back taper pressure valve core 12, at back taper pressure valve core 12 overcoat one wiper seal covers 13, a sealing function is played in the cooperation of 13 pairs of back taper pressure valve cores 12 of wiper seal cover and passage 11, thereby has guaranteed the sealing of back taper pressure valve core 12.
As shown in Figure 1, back taper pressure valve core 12 tail ends press a counterweight gland 20, the counterweight gland 20 tapered shapes in outer end, in counterweight gland 20 and back taper pressure valve core 12 cooperation places, leave a cavity 21, counterweight gland 20 is provided with through hole 22 at cavity 21 places, and through hole 22 is for losing heart, with depressurization.In addition, in counterweight gland 20 outer ends, establish a link slot 23, on link slot 23, connect one stroke balancing weight 30, stroke balancing weight 30 links into an integrated entity with counterweight gland 20 by embedding in the link slot 23 of counterweight gland 20, stroke balancing weight 30 matches with valve body 10, and limiting stroke by the gear shaft 14 on valve body 10, stroke balancing weight 30 is pressed in gear shaft 14 lower ends.
As shown in Figure 1, in use, increase due to gas pressure in pressure cooker, but when its pressure is greater than the self gravitation of counterweight gland 20 and stroke balancing weight 30, in pressure cooker, gas ejects back taper pressure valve core 12, back taper pressure valve core 12 heads on counterweight gland 20 and moves upward, when there is gap between back taper pressure valve core 12 and passage 11, gas is gone out and enters in the cavity 21 of counterweight gland 20 from passage 11, from the through hole 22 of counterweight gland 20, discharge, thereby reduce the pressure of gas.Moving upward in process of counterweight gland 20, stroke balancing weight 30 also moves upward along valve body 10 under the drive of counterweight gland 20, but it finally can be blocked by gear shaft 14, therefore define its movement travel, also stoped moving upward of counterweight gland 20, prevented that counterweight gland 20 from departing from the phenomenon generation of valve body 10 simultaneously.
As shown in Figure 1, limiting valve of pressure cooker of the present invention adopts the cooperation of counterweight gland 20 and stroke balancing weight 30, utilize the self gravitation of counterweight gland 20 and stroke balancing weight 30 to carry out pressure limiting, therefore can adjust different pressure according to actual conditions, by adjusting counterweight gland 20 and the stroke balancing weight 30 of Different Weight, realize, and, when pressure cooker is worked, can there is not the inefficacy of counterweight gland 20 and stroke balancing weight 30 and produce potential safety hazard, and pressure is controlled constant zero deflection, there is pressure stability, use safety, advantages of simple structure and simple, there are good market prospects.
According to embodiments of the invention describing the present invention property and nonrestrictive description, but should be understood that in the situation that not departing from relevant protection domain defined by the claims, those skilled in the art can make change and/or revise.
