Problems solved by technology
[0003] When checking and maintaining the safety pump, it is necessary to disassemble and assemble the safety pump. However, most of the existing safety pumps and discharge boxes are connected by bolts. The disassembly and assembly of this connection method is quite time-consuming and affects work efficiency. , Moreover, after reinstallation, if the bolts are not tightened and become loose, it will cause a safety accident

The invention discloses a pump-used safety valve and a twin-screw pump thereof. The twin-screw pump comprises an electromotor, wherein the output end of the electromotor is rotatably connected with ascrew pump body; a safety valve body is arranged on the surface of the screw pump body; a valve sleeve is connected with the surface, far away from one end of the screw pump body, of the safety valvebody in a sleeving manner; an unloading box is arranged at the bottom of the screw pump body; the top of the unloading box is fixedly connected with a connecting plate; the connecting plate is connected with the valve sleeve; a limiting handle is arranged on the surface of the connecting plate; a limiting rod is fixedly connected with one end of the limiting handle; a limiting plate is arranged onthe surface of the limiting rod; a limiting spring is arranged on one side of the limiting plate; and the limiting plate is connected with the connecting plate through the limiting spring. Accordingto the twin-screw pump, through mutual cooperation of a limiting device and a bolt rod, the safety valve and the unloading box are fixedly connected; and the twin-screw pump is simple in structure andconvenient to operate, saves more time and labor and improves the working efficiency compared with the traditional fixing bolt connecting manner.
Description
technical field [0001] The invention relates to the technical field of safety valves, in particular to a safety valve for a pump and a twin-screw pump thereof. Background technique [0002] Screw pumps are divided into single screw pumps, double, three and five screw pumps according to the number of screws. The screw pumps are characterized by stable flow, small pressure pulsation, self-priming ability, low noise, high efficiency, long life and reliable operation; The outstanding advantages are that no eddy current is formed when conveying the medium, it is not sensitive to the viscosity of the medium, and it can convey high-viscosity medium. The safety valve is an essential safety accessory of the screw pump, which is used to protect the safety of the pump body and the safety of the user. When the pump body is blocked, open the safety valve to release the pressure in time to ensure the safety of transportation. [0003] When the safety pump is to be inspected and maintaine...
