Abstract

The utility model relates to a pressure-limiting deflation valve of a pressure cooker, particularly to an adjustable pressure-limiting deflation valve of a pressure cooker, which comprises a valve seat, an exhaust pipe and a valve body, the upper end of the valve seat is made into point-by-point upward lower coils, and the exhaust pipe is arranged in the middle of a valve seat hole; a metal briquetting, a valve needle and a plastic sleeve are arranged on the valve body, point-by-point upward upper coils matched with the upper end of the valve seat are arranged on the lower edge of the plastic sleeve or the briquetting of the valve body, when the valve body rotates, the original valve needle for blocking the exhaust pipe elevates and lifts off an exhaust pipe hole gradually. With simple structure and low cost, the utility model can release pressure quickly after the cooking, shorten the uncovering time, and is conductive to production and sales.

Description

Adjustable pressure cooker pressure limiting vent valve

Affiliated technical field

The utility model relates to a kind of adjustable pressure cooker pressure limiting vent valve.The utility model indication pressure cooker comprises usual pressure pot and auto-electronic pressure cooker.

Background technology

Need just can be uncapped after waiting float-controlled valve to descend automatically after the tradition pressure cooker was cooked, and the time is too of a specified duration.Though Granted publication number be CN100563522C the patent utility model a kind of adjustable pressure limiting vent valve, accelerate the release speed of uncapping, its structure is complicated, technological requirement is higher, is unfavorable for producing in enormous quantities selling.

Summary of the invention

In order to overcome the deficiency of existing pressure cooker, the utility model provides a kind of adjustable pressure cooker pressure limiting vent valve.The technical scheme that its technical problem that solves the utility model adopts is: adjustable pressure cooker pressure limiting vent valve is made of valve seat, blast pipe and valve body, the following bung flange that pointwise makes progress is made in the valve seat upper end, blast pipe is middle in valve seat orifice, valve body has metal briquetting, needle and plastic sheath, the last bung flange that the plastic sheath of valve body or briquetting lower edge have the pointwise with valve seat upper end coupling to make progress, when the rotation valve body, the needle that sealed blast pipe originally can raise gradually and be lifted away from exhaust duct aperture.

The beneficial effects of the utility model are, can be under the situations of guarantee of work safe pressure, can continuously adjustable venting release after finishing when cooking and do not spray soup, and accelerate release venting speed, and simple in structure, cost is lower.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is valve seat and blast pipe aufbauprinciple schematic diagram.

Fig. 2 is first kind of valve body aufbauprinciple schematic diagram.

Fig. 3 is second kind of valve body aufbauprinciple schematic diagram.

Fig. 4 is the schematic diagram of first kind of valve body when being incorporated into valve seat sealing exhaust duct aperture.

1. blast pipes among the figure 2. descend bung flange, and are 3. high-end, 4. valve seat, and 5 low sides, 6. pot cover, 7 plastic sheaths, 8. group hand is 9. gone up bung flange, 10. needle, 11. pots of bodies, 12. briquettings.

The specific embodiment:

As shown in Figure 1, valve seat (4) is on pot cover (6), and the following bung flange (2) that pointwise makes progress is made on its top, and following bung flange has high-end (3) and low side (5), and middle in the valve seat orifice have blast pipe (1), and blast pipe is connected on the pot cover.

Fig. 2 is first kind of valve body, and as shown in the figure, valve body has briquetting (12), and there is needle (10) the briquetting middle and upper part, and briquetting is with plastic sheath (7) outward, and plastic sheath can have the hand (8) of dialling.Plastic sheath is longer than in the briquetting lower end of Fig. 2, the last bung flange (9) that jacking cover lower end has pointwise to make progress, and last bung flange has high-end (3) and low side (5).The briquetting external diameter is more a little bit smaller slightly than valve seat bore, and both are complementary and valve body is rotated easily and seal exhaust duct aperture and make valve body not too deflect away from valve seat.

Fig. 3 is the valve seat that briquetting is longer than in the plastic sheath lower end, and briquetting is made the last bung flange (9) that the lower end has pointwise to make progress, and last bung flange has high-end (3) and low side (5).

Fig. 4 is the schematic diagram the when valve body of Fig. 2 is incorporated into valve seat sealing exhaust duct aperture.As shown in Figure 4, the hole of the needle of valve body aligning blast pipe, put down valve body, hand (8) is dialled in rotation makes valve body drop to extreme lower position.Bung flange on this moment (9) can just contact down bung flange (2), also can not touch (all embodiment of this paper represent that bung flange just touches up and down).Briquetting is that metal is done, and makes needle push down exhaust duct aperture by its weight, and at this moment needle seals the valve exhaust pore fully.When pressure not during overrate, needle relies on its weight sealing exhaust duct aperture when cooking at ordinary times, and when the pot inner pressure overrate, needle is by air pressure jack-up and the release of exitting makes pot inner pressure can not surpass safe pressure.When boiling soup, congee class liquid object, food has boiled and when needing that release is uncapped as early as possible in the pot, hand (8) is dialled in (or counterclockwise, deciding on the design direction of bung flange) rotation clockwise, and at this moment valve body can raise gradually along bung flange, needle also raises and is lifted away from exhaust duct aperture gradually, be lifted away from highly more, it is fast more to exit, and can be transferred to firm venting and the position of not spraying water, allow its venting release then, can many a times time release than cooling naturally is fast like this.

Fig. 5 is the schematic diagram the when valve body of Fig. 3 is incorporated into valve seat sealing exhaust duct aperture.Its principle is identical with Fig. 4, and the parts that last bung flange is just arranged are briquetting rather than plastic sheath.

Here illustrate that bung flange up and down of the present utility model can be a complete circle, can not be a complete circle also, it can make other shape.Bung flange is that pointwise makes progress, and also is that pointwise is downward, and pointwise upwards but system is said so.The utility model still can have other accessory, in this omission.Or the like.

Claims

1. an adjustable pressure cooker pressure limiting vent valve is characterized in that being made of valve seat, blast pipe and valve body, and the following bung flange that pointwise makes progress is made in the valve seat upper end, and blast pipe is middle in valve seat orifice; Valve body has metal briquetting, needle and plastic sheath, the last bung flange that the plastic sheath of valve body or briquetting lower edge have the pointwise with valve seat upper end coupling to make progress, and when rotating valve body, the needle that sealed blast pipe originally can raise gradually and be lifted away from exhaust duct aperture.
