Abstract
The utility model discloses a pressure releasing valve which comprises a valve base, a glue film disc and a spring, and further comprises a mounting flange, a shield and a screw rod. The bottom of the valve base is provided with the mounting flange which is used for being connected with an oil conservator conveniently. The top of the valve base is provided with the glue film disc, the top of the glue 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 shield. The two sides of the valve base are provided with mounting holes, and the shield is arranged above the valve base through the screw rod and the mounting holes in the valve base. According to the pressure releasing valve, through the design of the mounting flange, field installation is facilitated; the shield can effectively protect against the rain and moisture; through the design of a baffle, the danger of deformation of the spring caused by too large jet pressure can be effectively avoided; an interface for remote monitoring is provided as well.
Description
Technical field
The utility model relates to a kind of pressure relief valve, belongs to transformer safety device technical field.
Background technique
At present, existing pressure relief valve due to rainproof, humidity resistance is not good, causes spring corrosion,, after camber of spring, cannot rebound and use when excessive at ejection pressure.
Model utility content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of pressure relief valve.
Technological scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of pressure relief valve, comprises valve seat, glued membrane dish, spring, also comprises mounting flange, guard shield, screw rod, and described valve seat bottom is provided with mounting flange, is connected with oil conservater for being convenient to; Described valve seat top is provided with glued membrane dish, and described glued membrane dish top is connected with spring one end, and the spring the other end is connected with guard shield inwall; Described valve seat both sides are provided with mounting hole, and described guard shield is arranged at valve seat top by the mounting hole on screw rod and valve seat.
Also comprise mark axle, described mark axle bottom is connected with glued membrane dish central top, and the mark axle the other end, through the through hole on guard shield, can move up and down along guard shield through hole.
Also comprise baffle plate, described baffle plate is vertically installed in mark axle sidewall, for the distance that coordinates spring restriction glued membrane dish to rise.
Also comprise switch contact, terminal box, described switch contact is arranged at respectively on baffle plate end face, guard shield inwall; Described set of terminal box is on guard shield outer side wall; While being used for glued membrane dish by jack-up oil spout, switch contact is conducted, and forms loop by terminal box and remote alarming system.
As preferred version, also comprise rubber sleeve, described rubber sleeve is socketed on mark axle top, for preventing that rainwater from flowing in guard shield through hole.
As preferred version, described mounting flange diameter is set to 235mm, for coordinating total oil mass to be greater than the oil conservater of 31.5t.
Beneficial effect: the pressure relief valve that the utility model provides, by the design of mounting flange, be convenient to on-the-spot installation; Guard shield can be effectively rainproof, moistureproof; The design of baffle plate, can effectively prevent that spring is due to the excessive risk of being out of shape of ejection pressure; And provide the interface of remote monitoring.
