Description
Technical Field
The utility model relates to a cooking utensil field particularly, relates to a relief valve, pot cover and cooking utensil.
Background
When people use the pressure cooker, the pressure relief valve needs to be arranged on the pressure cooker, when the pressure limiting valve in the pressure cooker is clamped or the air leakage hole is blocked, and the pressure in the pressure cooker exceeds the normal working pressure at the moment, the pressure relief valve can automatically start to discharge steam in the pressure cooker, so that the pressure cooker is prevented from being exploded in the using process.
Present relief valve is in the use, the condition that needs quick pressure release often can appear, but present relief valve only relies on inside atmospheric pressure of pressure cooker to ejecting with the case in the relief valve, but inside atmospheric pressure lasts the in-process of pressure release, the unstable condition of atmospheric pressure can appear, the case can the snap-on in the use has been caused, the unstable condition of relief valve pressure release has been caused, and for the convenience of adjusting or easy to assemble, present relief valve sets up in the pot cover outside usually, the pressure cooker has been caused when setting up the relief valve, the whole outward appearance of pressure cooker has been influenced, because the relief valve sets up in the outside, make the condition such as hook up carelessly appear easily in the use, the use that has led to the relief valve has insecurity, the stability that the relief valve used has been reduced.
Disclosure of Invention
The utility model aims at providing a relief valve, pot cover and cooking utensil to solve the relief valve among the prior art at the pressure release in-process, can be in the existence unstable when pot atmospheric pressure, and lead to the unstable problem of relief valve pressure release.
In order to achieve the above object, according to one aspect of the present invention, a pressure relief valve is provided, including a valve body, an air inlet and a pressure relief hole are opened on the valve body, a valve element capable of connecting or disconnecting the pressure relief hole and the air inlet is slidably installed in the valve body, the valve element includes a plugging portion and a hook portion, the upper end of the plugging portion is connected with the lower end of the hook portion, the lower end of the plugging portion is capable of plugging the air inlet, the upper end of the hook portion is slidably disposed in the pressure relief hole, the valve element moves upward under the push of air pressure, so that the plugging portion opens the air inlet, and the hook portion slides along the pressure relief hole at the same time; the hook part moves to extend out of the valve body and then inclines relative to the upper end of the blocking part to be placed on the valve body, so that the air inlet is communicated with the pressure relief hole.
The working principle is as follows: when atmospheric pressure is in the normal value, the upper end setting of portion colludes is in the pressure release hole, and the lower extreme of shutoff portion carries out the shutoff with the inlet port, and when atmospheric pressure was too big, can jack-up the case, the case breaks away from valve body upward movement this moment, in the upward movement in-process, because the lower extreme of portion colludes is connected with the upper end of shutoff portion, when atmospheric pressure is great, collude the portion and slide along the pressure release hole, after colluding the portion motion to stretching out the valve body, collude the portion and empty for shutoff portion upper end, and shelve on the valve body and make inlet port and pressure release hole intercommunication, the pressure release process has been realized, through the setting of portion colluding and shutoff portion, make whole relief valve pressure release process stable, the stability of pressure release valve has.
Furthermore, the upper end of the plugging part is rotatably connected with the lower end of the hook part; the hook part rotates around the upper end of the plugging part after moving to extend out of the valve body along with the valve core and is placed on the valve body.
The connection mode between shutoff portion and the portion of colluding for when colluding the portion and moving outside stretching out the valve body, collude the portion and can rotate around the upper end of shutoff portion and shelve on the valve body, collude the portion and can more conveniently shelve on the valve body, further improvement the stability of relief valve pressure release.
Further, the hook part comprises a convex edge and a connecting rod, the weight of the convex edge is larger than that of the connecting rod, the convex edge is matched with the pressure relief hole, and the lower end of the connecting rod is connected with the upper end of the blocking part.
The connecting rod can be connected with the shutoff portion, when jacking up the case, because the weight on protruding edge is greater than the weight of connecting rod, leads to the swing that protruding edge can be quick, and protruding edge can be more stable collude and establish on the outer top surface of valve body to can carry on spacingly and block colluding the portion, protruding edge has one this moment and stops the power, can be with colluding the upper end of portion spacing on the outer top surface of valve body, further improvement the stability of pressure release valve.
Further, the width of the cross section of the convex edge is larger than that of the connecting rod.
When ejecting the valve body with protruding edge, protruding edge can be stable sets up on the outer top surface of valve body, and when atmospheric pressure was normal, protruding edge can be stable sets up downtheholely at the pressure release, further improvement the stability of relief valve.
Further, the convex edge and the connecting rod are integrally formed.
The setting of this structure for the simple structure of case, and protruding edge and the connecting rod between stability better, and install convenience more, further improvement the stability of relief valve.
Furthermore, the hook part and the plugging part are integrally formed, a convex edge for increasing the eccentric weight extends towards one side from the upper end of the hook part, which is far away from the plugging part, and the convex edge is movably accommodated in the pressure relief hole.
The setting of this structure, case adopt the integral type structure for the installation of case is simpler, and protruding edge only extend on one side of shutoff portion upper end, and protruding edge increases eccentric weight, makes protruding when external along ejecting valve, and the case can be towards protruding one side skew of increasing eccentric weight along, and makes protruding edge can be stable set up on the outer top surface of valve body, and can be stable carry out the pressure release.
