Abstract

The invention discloses a pressure relief valve. The pressure relief valve comprises a valve base, an adhesive film disc, a spring, an installation flange, a protecting cover and screws. The installation flange is arranged at the bottom of the valve base and used for being conveniently connected with an oil conservator. The adhesive film disc is arranged at the top of the valve base, the top of the adhesive film disc is connected with one end of the spring, and the other end of the spring is connected with the inner wall of the protecting cover. The two sides of the valve base are provided with installation holes, and the protecting cover is arranged above the valve base through the screws and the installation holes in the valve base. According to the pressure relief valve, through the design of the installation flange, on-site installation is facilitated; the protecting cover can effectively prevent rain and damp; through the design of a baffle, the risk that the spring deforms due to overlarge ejection pressure can be effectively avoided; an interface for remote monitoring is provided.

Description

technical field [0001] The invention relates to a pressure relief valve, which belongs to the technical field of transformer safety devices. Background technique [0002] At present, due to poor rainproof and moistureproof performance of the existing pressure release valve, the spring is corroded. When the ejection pressure is too high, the spring is deformed and cannot be rebounded and used. Contents of the invention [0003] Purpose: In order to overcome the deficiencies in the prior art, the present invention provides a pressure release valve. [0004] Technical solution: In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: [0005] A pressure relief valve, including a valve seat, a film disc, a spring, and also includes a mounting flange, a shield, and a screw rod. The bottom of the valve seat is provided with a mounting flange for easy connection with an oil conservator; the valve There is a film disk ...
