Automatic radiator exhaust pneumatic valve how to choose and install?

how automatic radiator exhaust pneumatic valve selection and installation method is introduced, and new type radiator, now in exhaust pneumatic valve choice, is to choose automatic exhaust pneumatic valve, has been out of the thought that the history of the manual vent pneumatic valve, then the radiator automatic exhaust pneumatic valve, how to choose? Installation and how to install?
radiator/radiator automatic exhaust pneumatic valve selection and installation method is introduced: how
' Automatic radiator exhaust pneumatic valve synopsis 】 Used in heating systems such as heating, floor heating, blades of the boiler system to exclude a functional system air pneumatic valve, usually installed in the highest point of the system, or directly with manifold, heat patches of systems. Mainly to remove internal air, make the heating patches of inside is full of warm water, ensure that the room temperature.
　　【 Automatic radiator exhaust pneumatic valve function 】 。 Vent gas hole open hot water channel, put an end to radiator is not warm; 。 Slow down the speed of the hot water pipe rust, pipeline with oxygen, and high temperature environment, the corrosion speed quickly, unless it is stainless steel pipe. But most people don't use well, 。 Eliminate the air lock, so that the circulating water pump suction, prevent water pump air to burn.
　　【 Automatic radiator exhaust working principle of the pneumatic valve 】 When system in gases, due to the lower density than water gas, gas will go up down pipe, high eventually gathered in system, so the automatic exhaust high pneumatic valve is generally installed in the system, automatic exhaust pneumatic valve exhaust efficiency highest here. When the gas into the automatic exhaust pneumatic valve pneumatic valve cavity gathered in the upper portion of the automatic vent pneumatic valve, along with the increase in gas inside the pneumatic valve, gas pressure rise. When the gas pressure is greater than the system pressure, gas can make the cavity of the water drops, buoy with water level drops, vent opening began to exhaust; With gas discharge, the pressure is reduced, water level rise, buoy also rose, vent closed.
　　【 Automatic radiator exhaust pneumatic valve how to choose the 】 According to the different installation environment, radiator automatic exhaust pneumatic valve ( Vent pneumatic valve) Selection has the following three conditions:
. Peak is a vertical pipe, and the enough space can choose stand-up in-line automatic radiator exhaust pneumatic valve ( Vent pneumatic valve
. Peak is a vertical pipe, but the installation space is not enough can choose lateral stand-up row radiator automatic exhaust pneumatic valve ( Vent pneumatic valve
. Balance is high water branch pipe, the installation space is not enough cases can choose right Angle type radiator automatic exhaust pneumatic valve ( Vent pneumatic valve) , if the installation space and no enough right Angle type, you can install a ° elbow, and then install stand-up rows or side.
　　【 Automatic radiator exhaust pneumatic valve installation 】 , automatic radiator exhaust pneumatic valve must be installed vertically to the ground, must ensure that the pneumatic valve body buoy is in vertical position, can't stand or horizontal installation;
, automatic exhaust device due to the smaller gas density than water along the pipe will climb to the highest point system and gathered here, in order to improve the efficiency of exhaust, exhaust the commanding heights of the pneumatic valve is generally installed in the radiator system;
, in order to facilitate the radiator system maintenance, exhaust pneumatic valve with pneumatic valve partition commonly use, so remove exhaust pneumatic valve is
do not need to shut down system, after installation of radiator automatic exhaust device have to unscrew the nut to exhaust, but not all turned on, beware of a large amount of water, exhaust after you tighten the dust cap.
