The choose and buy of thermostatic valve
the choose and buy of thermostatic valve method under the thermostatic valve factory is to show you have an idea of how to choose high performance thermostatic valve. 1, bulb the thermostatic valve brand on the market and the choice of various kinds, bulb medium mainly can be divided into the following three: package solid temperature, liquid temperature bag, the gas temperature package; Solid state bulb a longer reaction time, feel the room temperature lag, but has great execution, in case of need to valve can be completely shut up; Gaseous bulb short reaction time, responding quickly to room temperature deviation, but in some cases, the valve closed tightly may happen; And package liquid temperature reaction time is moderate, the execution is moderate, is a good bulb medium, is also the mainstream imported brand mainly choose the bulb medium. 2, the valve body material of the thermostatic valve body material is good or not directly affects the service life of the valve body, choose the material with high corrosion resistance can prolong the service life of the valve. Currently on the market are mostly use the brass material, a small amount of higher product will use higher performance of gun metal.
3, the executive force of the spring in the constant temperature valve core thermostatic valve manufacturer to prompt the executive force of the spring in the constant temperature valve core will directly affect the adhesion of valve. If the constant temperature valve core used in spring with poor execution, after heating season, thermostatic valve has been closed, when the second heating system using a thermostatic valve, will find thermostatic valve has the adhesion situation, radiators without water, always need to use pliers will be pulled up to the valve core to normal use, it will bring unnecessary trouble to households. And with high executive force of spring, even if the valve has been in a state of closure, also won't appear adhesion, spring always have enough execution can separate the valve core and valve base, late can make maintenance easier. 4, thermostatic valve core of the thermostatic valve sealing performance in adhesion is not only related to the executive force of the spring inside the thermostatic valve core, and also has relations with the sealing performance at the ends of the spring, if the spring rusting, will weaken the executive force of spring. Therefore, we need to do sealing with spring, prevent it from contact with the water. Generally think that as long as the spring under the disposal of the waterproof seal is enough, but it's not that good in the thermostatic valve core for spring are set the seal on both ends of the up and down, the bottom of the sealing ring is to prevent to into the spring of the water in the radiator, the upper part of the sealing ring is to prevent moisture from the atmosphere into the rust occurs in the spring, which can guarantee the spring in a state of completely without water, will not rust, guarantees the high execution.
