Abstract

The invention discloses a butterfly bamper for a lifter pump station. The butterfly bamper comprises a hand wheel and a worm gear box, the hand wheel is located on the side portion of the worm gear box and rotates in cooperation with the worm gear box, and a connection seat is arranged below the worm gear box; the butterfly bamper is characterized in that the butterfly bamper is arranged below the connection seat, a bamper rod penetrates through the worm gear box, the connection seat and the butterfly bamper, the lower portion of the bamper rod is connected with a bamper plate, and the bamper rod is fixedly connected with the bamper rod and can rotate along with the bamper rod. According to the butterfly bamper, the butterfly bamper is operated to be opened and closed in a worm and gear transmission mode, the transmission is more effective and practical, the flow of hydraulic oil can be controlled quite well, the connection seat is internally provided with a packing gland, and connection between the bamper rod and the connection seat can be closer.

Description

Technical field: [0001] The invention relates to the technical field of hydraulic pump station equipment, in particular to a butterfly valve used in an elevator pump station. Background technique: [0002] The pump station is an important part of the elevator. The pump station is mainly a hydraulic source device composed of a hydraulic pump, a motor, a fuel tank, a directional valve, and a relief valve. The hydraulic system can realize various specified actions. The motor drives the oil pump to rotate. The pump pumps oil after absorbing oil from the oil tank, and converts mechanical energy into pressure energy. The butterfly valve is a part between the hydraulic pump and the oil tank that is responsible for the switch of the pipeline. It can control the flow of hydraulic oil entering the hydraulic pump and plays an important role in the work of the hydraulic pump. The butterfly valves in the prior art only have a simple gear transmission to control the rotation of the valve...
