Abstract
The utility model relates to a safety valve of a pressure cooker, particularly a decompression valve, which comprises a valve core and a valve seat, wherein, the valve core is inserted in the valve seat by an inner gasket. A convex loop in the center of the valve core is provided with a cross bore in which an auxiliary spring is arranged, and each of both ends of the auxiliary spring is provided with a steel ball; a main spring is arranged on the convex loop; the lower part of the valve seat is provided with a screw opening which is screwed with a screw nut, the center of the valve seat is provided with a plurality of pores in radial direction, and the pores are positioned above the cross bore; the valve core is sheathed with the main spring, the upper end of the valve seat is screwed with a valve hood of which the center is provided with a through hole so the valve core can penetrate out through the through hole. Because the utility model is provided with a jumping non-return device which has the effect that the valve core can be prevented from rebound when the valve core jumps to ensure sustained pressure relief, the safe use can be ensured.
Description
Technical field
The utility model relates to a kind of safety valve of pressure cooker, and particularly a kind of relief valve is applicable to the aluminium and the aluminium alloy pressure cooker of the various capacity of existing national regulation.
Background technology
The exhaust of existing pressure cooker safety valve is slow, just not exhaust when the certain pressure, and this just brings potential safety hazard to the user.
Summary of the invention
The purpose of this utility model is that a kind of being provided with in valve core inside of invention opened the relief valve of jumping check device, and opening the effect of jumping check device is in a single day to open jumping at spool can stop its rebound, guaranteeing to continue pressure release, thereby guarantees the safety used.
The utility model is realized as follows: described relief valve comprises spool and valve seat, spool is plugged in the valve seat by inner seal ring, drop on the inner ring of valve seat bottom, on the central protruding circle of spool, offer a cross-drilled hole, be provided with in the cross-drilled hole and pay spring, the two ends of paying spring respectively are provided with a steel ball, be provided with main spring above the protruding circle, the bottom of valve seat is a screw socket, it is bolted with nut by exterior seal ring, and the central authorities of valve seat radially offer a plurality of holes, and this hole is positioned on the cross-drilled hole, valve core upper sleeve is provided with main spring, the upper end snail of valve seat is connected to valve gap, and valve gap makes main spring be in pressured state, and the center of valve gap has through hole, spool is passed thus, partly be inserted with bonnet passing of spool.
During use, the utility model links to each other with the pot body by nut, when the pot inner pressure superpressure, and air-flow jack-up spool, the beginning pressure release, at this moment, steel ball will be stuck on the hole that valve seat central authorities are radially offered, and realize the function of its spool non-return.
Good effect of the present utility model is as follows: because the utility model is provided with in valve core inside and opens the jumping check device, opening the effect of jumping check device is in a single day to open jumping at spool can stop its rebound, guaranteeing to continue pressure release, thereby guarantees the safety used.
