Water tank inlet pipe water flow noise reduction and vibration damping mute device

Abstract

The invention discloses a water tank inlet pipe water flow noise reduction and vibration damping mute device. The device is characterized by comprising a water inlet silencing pipe, a transition sleeve and a water outlet pipe, one end of the water inlet silencing pipe is provided with a thread, the other end of the water inlet silencing pipe is embedded in the transition sleeve, the other end of the transition sleeve is connected to one end of the water outlet pipe, and the other end of the water outlet pipe is provided with a thread. The device has simple overall structure, small volume, light weight, high strength, good noise reduction effect and convenient installation and maintenance, and can reduce the water flow pressure in a water pipe, when the device is installed at the front endof a float ball valve, it is avoided that water blockage occurs and noise and vibration are generated when a high-pressure water flow directly impacts a valve body, when the device is installed at anoutlet of the float ball valve, the pressure difference between the inlet and outlet of the float ball valve is reduced, the vibration of a pipeline and the noise when the water flow flows through thevalve body are reduced, the direct impact of the water flow from an outlet of the pipeline to the water tank is discomposed, and the device is suitable for being used as a mute noise reduction damperduring municipal water supply.

Description

technical field [0001] The invention relates to the field of mute devices, in particular to a noise-reducing and shock-absorbing mute device for water flow in a water tank inlet pipe. Background technique [0002] At present, the secondary water supply usually uses a water tank to store water and then supply it to the user. The water intake of the water tank generally adopts a purely mechanical float valve to realize automatic control of the liquid level. The control principle is: use the floating ball to control the switch of the valve. The floating ball changes with the water level of the water tank. When the water level of the water tank drops, the valve opens gradually; Under normal circumstances, the municipal water supply has a pressure of 2-4MPA. When the float valve is opened to replenish water to the water tank, the structure of the float valve body causes the water flow channel to bend. Vibration affects the life of residents; at the same time, due to the high pre...

AI Technical Summary

Problems solved by technology

Under normal circumstances, the municipal water supply has a pressure of 2-4MPA. When the float valve is opened to replenish water to the water tank, the structure of the float valve body causes the water flow channel to bend. Vibration affects the life of residents; at the same time, due to the high pressure and fast water flow, the pressure drops sharply after the water flows out of the valve body through the valve body. When the water pipe directly enters the water tank, it will cause impact on the water tank body and generate noise. Long-term impact will reduce the service life of the water tank
