Constant Pressure Water Supply Device

Key words：Water Filter、UV Sterilizer、Ion Exchange Water softener

YL series airtight expansion water tank (automatic bladder-type pressure stabilization and constant pressure water tank) is developed on the basis of automatic air pressure water supply equipment. Its working principle is to use the compressible gas in the airtight pressure tank to store, To adjust the hot water system, the water volume shrinks or expands due to temperature changes. A bladder-shaped diaphragm is installed in the closed pressure tank, which divides the tank into an air chamber and a water chamber. When the water temperature increases, the water capacity increases. When the gas in the tank is compressed, the expanded water enters the water chamber. When the water temperature drops, the water capacity decreases, the gas expands, and the water in the water chamber enters the system pipe network. If the pipe network leaks, the pressure value of the pipe network cannot reach the set pipe. When the pressure of the network is increased, the water pump will supplement it to the set pressure to achieve the purpose of constant pressure and constant pressure.

Introduction

YL series airtight expansion water tank (automatic bladder-type pressure stabilization and constant pressure water tank) is developed on the basis of automatic air pressure water supply equipment. Its working principle is to use the compressible gas in the airtight pressure tank to store, To adjust the hot water system, the water volume shrinks or expands due to temperature changes. A bladder-shaped diaphragm is installed in the closed pressure tank, which divides the tank into an air chamber and a water chamber. When the water temperature increases, the water capacity increases. When the gas in the tank is compressed, the expanded water enters the water chamber. When the water temperature drops, the water capacity decreases, the gas expands, and the water in the water chamber enters the system pipe network. If the pipe network leaks, the pressure value of the pipe network cannot reach the set pipe. When the pressure of the network is increased, the water pump will supplement it to the set pressure to achieve the purpose of constant pressure and constant pressure.

Scope of application

1. High temperature water continuous heating system;
