Valve with good water stopping effect

Abstract

The invention discloses a valve with a good water stopping effect. The valve comprises a valve body, water baffles are fixedly connected to the top of the inner cavity of the valve body, control grooves are formed in the inner sides of the water baffles, sliding blocks are arranged in the control grooves, water retaining blocks are fixedly connected to one side of the sliding blocks, the water retaining blocks are connected with the control grooves through sliding blocks in a sliding mode, and the tops of the water retaining blocks are fixedly connected with threaded cylinders. According to the valve, a motor, a connecting shaft and a first rotating gear are arranged, the first rotating gear is driven to rotate by means of the operation of the motor to provide power for opening and closingof the valve body; a supporting shaft, a second bevel gear and second rotary gears are arranged, the second bevel gear is used for transmitting the rotation and changing the rotation direction at thesame time to drive the second rotary gears to rotate, and based on relative rotation between the threaded cylinders and threaded rods, the water retaining blocks rise and fall to control the passingof the water flow; and a plurality of water stopping grooves and water stopping strips are arranged, and the water stopping strips are used for absorbing water to expand to improve the water blockingeffect.

Description

Technical field [0001] The invention relates to the technical field of valves, in particular to a valve with good water stopping effect. Background technique [0002] A water pump is a machine used to increase the pressure of liquid or gas and make it flow. It is a device used to move liquid, gas or special fluid media, that is, a machine that works on fluids. The water pump is in use. Valves are needed to control the water flow. Valves range from the simplest globe valve to the various valves used in extremely complex automatic control systems. There are quite a lot of varieties and specifications. Valves are also divided into cast iron valves, cast steel valves, Stainless steel valves, chromium-molybdenum steel valves, chromium-molybdenum-vanadium steel valves, duplex steel valves, plastic valves and non-standard customized valve materials, but in the process of closing the water valve, the closing effect is not good, and it cannot effectively block the water flow. Overflow, l...
