The invention discloses an anti-loosening safety valve. The valve comprises a valve seat, a valve cover and a valve element, wherein the valve seat comprises an installing hole penetrating through the inner side and the outer side of the valve seat; the valve cover is located at the outer side of the valve seat and corresponds to the installing hole so as to cover the installing hole, and a pressure relief structure is further arranged on the valve cover; one end of the valve element is connected with the valve cover, the other end of the valve element extends into the inner side of the valve seat, a sealing part and a buckling part are sequentially arranged on the valve element in the extending direction towards the inner side of the valve seat at intervals, the sealing part abuts against the inner wall of the installing hole, and the buckling part is located at the inner side of the valve seat and abuts against the end face of the inner side of the valve seat. According to the scheme, the installing hole can be sealed, the sealing performance is good, the buckling part can limit the movement of the valve element in the installing hole, the situation that the valve cover is gradually separated from the valve seat is avoided, and therefore the requirement of a user for the sealing effect can be met.
Description
technical field [0001] The invention relates to the technical field of safety valves, in particular to an anti-loosening safety valve. Background technique [0002] In the existing safety valve, the valve seat is sealed by soft rubber. At the beginning, the safety valve is forcibly knocked into the valve seat to completely install the safety valve into the valve seat, but there is an obvious defect. In the process of knocking into the valve seat, there must be some twisting and deformation of the soft rubber part. In this way, after a period of time, the twisted and deformed soft rubber part on the safety valve will creep and stretch, thereby gradually distorting the safety valve. If the valve is pushed away from the valve seat, the bonnet of the safety valve will gradually be separated from the valve seat, resulting in poor user experience. Contents of the invention [0003] The main purpose of the present invention is to provide an anti-loosening safety valve, aiming to...
