Abstract
Pressure cooker pressure -limiting valve has the exhaust nozzle and the valve cap of mutually supporting, and the middle part of exhaust nozzle has along its axial through's through -hole, has blind hole and exhaust hole on the valve cap, and the exhaust hole communicates with each other with the blind hole, and the bottom of blind hole has an end cap that is the cone form, and the upper portion of exhaust nozzle has one section external screw thread, and the drill way position of blind hole has one section screw hole, and the external screw thread on screw hole and exhaust nozzle upper portion is the cooperation relation, and the diameter of screw hole is less than the diameter of blind hole. With continuous the closing soon of external screw thread on the screw hole on the valve cap and exhaust nozzle upper portion, finally make the screw hole pass through the external screw thread on exhaust nozzle upper portion, can make the port on the exhaust nozzle of taking a seat of the end cap freedom in the valve cap, after accomplishing above -mentioned process, even if make the exhaust nozzle last, the valve cap is downward, both can not break away from by oneself yet, consequently install the exhaust nozzle on the pot cover, combine the valve cap according to above -mentioned mode and exhaust nozzle again, the valve cap just can not come off easily. The utility model discloses it is rational in infrastructure, convenient to use.
Description
Technical field
The utility model relates to a kind of pressure limiting valve, specifically a kind of pressure limiting valve for pressure cooker.
Background technology
Pressure cooker is a kind of daily living article.The pot cover of pressure cooker needs be provided with a pressure limiting valve, the effect of pressure limiting valve is: when the air pressure in pressure cooker is higher than a setting value, pressure limiting valve is opened, be vented, to guarantee the use safety of pressure cooker; When the air pressure in pressure cooker is lower than this setting value, pressure limiting valve cuts out, to keep the pressure in pot.Existing a kind of limiting valve of pressure cooker is made up of exhaust nozzle and bonnet, and in use, exhaust nozzle is fixed on pot cover, and bonnet is directly taken a seat on exhaust nozzle by the blind hole on it.The shortcoming that this pressure limiting valve exists is: do not have anti-shedding mechanism between bonnet and exhaust nozzle, when pot cover tilts or overturn, and bonnet meeting self falling, pot cover and bonnet are difficult to together move, in use, put bonnet again after need first covering pot cover, equally at every turn, often secondary when opening pot cover, need first bonnet to be taken off, therefore, used time again after bonnet takes off, often occur being difficult to find the phenomenon of even losing for the moment, make troubles to use.
Utility model content
The purpose of this utility model is to provide a kind of limiting valve of pressure cooker, and after combining between the bonnet of this limiting valve of pressure cooker and exhaust nozzle, both can not depart from voluntarily.
For achieving the above object, the utility model adopts following scheme: limiting valve of pressure cooker, there is the exhaust nozzle and bonnet that cooperatively interact, the middle part of exhaust nozzle has along its axially through through hole, bonnet have blind hole and steam vent, steam vent communicates with blind hole, the bottom of blind hole has the plug in cone shape, the top of exhaust nozzle has one section of external screw thread, the position, aperture of blind hole has one section of screwed hole, the external screw thread on screwed hole and exhaust nozzle top is matching relationship, and the diameter of screwed hole is less than the diameter of blind hole.
From such scheme, the external screw thread on the screwed hole on bonnet and exhaust nozzle top is constantly screwed, after finally making the external screw thread of screwed hole by exhaust nozzle top, the plug in bonnet can be made to be landed in exhaust nozzle upper port freely, after completion of the above process, even if make exhaust nozzle downward at upper, bonnet, both also can not depart from voluntarily, only have and constantly screwed by the external screw thread on the screwed hole on bonnet and exhaust nozzle top again, just can make both separately.Therefore be arranged on pot cover by exhaust nozzle, then be combined with exhaust nozzle in a manner described by bonnet, bonnet would not come off easily, like this, operation or moving cooker lid process in, bonnet can with pot cover together arbitrarily movement.
The utility model is rational in infrastructure, easy to use.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model one embodiment.
Detailed description of the invention
The utility model is further illustrated below in conjunction with embodiment and accompanying drawing.
See Fig. 1
The limiting valve of pressure cooker that the utility model provides has the exhaust nozzle 3 and bonnet 2 that cooperatively interact, the middle part of exhaust nozzle 3 has along its axially through through hole 3b, bonnet 2 has blind hole 2b and steam vent 2d, steam vent 2d communicates with blind hole 2b, the bottom of blind hole 2b has the plug 2a in cone shape, the top of exhaust nozzle 3 has one section of external screw thread 3a, the position, aperture of blind hole 2b has one section of screwed hole 2c, the external screw thread 3a on screwed hole 2c and exhaust nozzle 3 top is matching relationship, and the diameter of screwed hole 2c is less than the diameter of blind hole 2b.
In the present embodiment, the bottom of exhaust nozzle 3 also has one section of external screw thread 3c, and this section of external screw thread 3c is equipped with nut 4.After on the pot cover that exhaust nozzle 3 is arranged on pressure cooker, by this section of screwed hole 3c and nut 4, the handle of pot cover and exhaust nozzle can be fixed.
In the present embodiment, the outer cover of bonnet 2 has the shell 1 of non-metallic material, and shell 1 has the venthole 1a communicated with the steam vent 2d on bonnet 2.The material of shell 1 can be bakelite or plastics etc., the setting of shell 1, scalds one's hand when can avoid dismantling the bonnet be heated.
Claims (3)
