Abstract
The utility model relates to an adjustable deflation valve used on a pressure cooker, which comprises a valve shell, a valve cover and a valve core, wherein, the valve cover is arranged on the top of the valve shell, and the valve core arranged in the valve shell presses the bottom of the valve cover. A stepped inrun is arranged on the inner wall of the valve shell, and a lug boss corresponding to the position of the inrun is arranged on the bottom of the valve cover; retaining blocks are respectively arranged on both ends of the inrun; exhaust holes communicated with the inside of the valve shell are arranged on the top of the valve cover. The adjustable deflation valve of the utility model, which is used on the pressure cooker, has the advantages of simple structure and convenient use.
Description
Technical field
The utility model relates to a kind of adjustable pressure pot vent valve.
Background technology
At present, be provided with vent valve on the pot cover of common pressure cooker on the market, its purpose is for passing through exhaust gear exhaust when the pressure cooker body internal pressure is excessive of vent valve, and in a relatively-stationary scope, the interior pressure stability of pot pot body keep-ups pressure with the pressure in the restriction pot body.Chinese patent application numbers 200410044481.2 discloses a kind of adjustable vent valve of pressure cooker, and its structure is that sloping platform is set on the valve gap of vent valve, is complementary with the last sloping platform that is arranged on the valve casing.By the rotation valve casing, adjust the position of sloping platform, reach and adjust the purpose that vent valve opens and closes amplitude.; in the vent valve of this structure; because last sloping platform is smooth connection with following sloping platform; thereby the in use easy phenomenon that the relative slippage of appearance between the sloping platform occurs causing because of capacity is excessive; last sloping platform automatically resets because of air-flow is excessive; reduced the opening degree of vent valve, exhaust velocity has slowed down.And in the vent valve of this structure, there is no locating part in its rotating mechanism, in use occur easily making valve gap return the state of adjustment because of excessively rotating.Therefore it uses very inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and adjustable pressure pot vent valve a kind of simple in structure, easy to use is provided.
Goal of the invention of the present utility model is achieved in that a kind of adjustable pressure pot vent valve, but comprise valve casing, be located at the valve gap at valve casing top and be located in the valve casing and the spool of roof pressure bottom valve gap, it is characterized in that: described valve casing inwall is provided with the staged sloping platform, and the valve gap bottom is provided with and the corresponding boss in sloping platform position.
Described sloping platform two ends are respectively equipped with block.
Described valve gap top has the steam vent with the valve casing internal communication.
The utility model improves with vent valve the adjustable pressure pot of prior art, and stepped sloping platform is set on the valve casing inwall, and is provided with and the corresponding boss in sloping platform position in the valve gap bottom.By the position of mobile boss, can make valve gap rise or descend along the direction of sloping platform.When the pressure cooker exhaust, air-flow promotes spool and moves up, until the spool roof pressure till the valve gap inner top surface.Thereby the exhaust velocity of vent valve is by the residing determining positions corresponding with sloping platform of boss, so vent valve can be realized the classification exhaust.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Accompanying drawing 2 is the structural representation of the utility model sloping platform.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to Figure 1 and Figure 2, adjustable pressure pot of the present utility model mainly is made up of valve casing 1, valve gap 2, spool 3, staged sloping platform 4 and boss 5 with vent valve.Wherein valve gap 2 is arranged at valve casing 1 top, and is socketed on the inwall of valve casing 1, and valve gap 2 is provided with the steam vent 7 with valve casing 1 internal communication, and steam vent 7 can be arranged on valve gap 2 tops, also can be arranged on valve gap 2 sides; Spool 3 is arranged in the valve casing 1, can move up and down along valve casing 1, but and roof pressure on the inner top surface of valve gap 2; Sloping platform 4 is located on valve casing 1 inwall, and boss 5 is arranged on the bottom of valve gap 2, and corresponding with the position of sloping platform 4.By the position of mobile boss 5, can make valve gap 2 rise or descend along the direction of sloping platform 4.When the pressure cooker exhaust, air-flow promotes spool 3 and moves up, until spool 3 roof pressures till valve gap 2 inner top surfaces.Thereby the exhaust velocity of vent valve is by the residing determining positions corresponding with sloping platform 4 of boss 5, and when boss 5 slides when rising along sloping platform 4, the exhaust velocity of pressure cooker is accelerated, otherwise then slows down.In order to guarantee that valve gap 2 can excessively not make boss 5 break away from the phenomenon of sloping platform 4 because of rotation occurring, is respectively equipped with block 6 at sloping platform 4 two ends.In order to guarantee boss 5 position stable on sloping platform 4, can buckle be set at the ladder end of sloping platform 4, also can be processed into taper serration to ladder.Adjustable pressure pot of the present utility model can make valve gap 2 rise or descend along the direction of sloping platform 4 with the position of vent valve by mobile boss 5, and the size that spool 3 is opened and closed can be regulated, and has realized that vent valve can the classification exhaust.
