Waterstop valve of water pump

Abstract

The invention discloses a waterstop valve of a water pump. The waterstop valve comprises a valve body, a servo motor is arranged on the top of the valve body, the output end of the servo motor is sleeved with a gear, the gear is engaged with a rack plate, the bottom of the rack plate is fixedly connected with the upper surface of a lifting plate, one side of the lifting plate is fixedly connected with the side surface of an anti-sliding sleeve, a main rod is sleeved with the interior of the anti-sliding sleeve, and the bottom end of the main rod sequentially penetrates the top of the valve body and a fixed sleeve from top to bottom and is fixedly connected with the top end of a movable rod; the improvement of a solid telescopic soft sleeve and a hollow telescopic soft sleeve achieves the waterstop and water draining effect, and the improvement of a seal layer and a through groove achieves the effect of preventing water from flowing out of the gap, through the improvement of a baffle, the water can be stopped in time, water is prevented from backflowing, and therefore the effect of improving the work efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a water stop valve of a water pump. Background technique [0002] A pump, a machine used to increase the pressure of a liquid or gas to make it flow, is a device used to move a liquid, gas or special fluid medium, that is, a machine that does work on the fluid. The water pump needs to use valves in the process of use to control the water flow. The valves range from the simplest shut-off valve to various valves used in extremely complex automatic control systems. There are quite a variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, duplex steel valves, plastic valve...
