Machine type selection is a complicated process, it is a conundrum for many people. Only the right product, can play a biggest role, exert its maximum value. Small make up next to depth analysis flanged gate valve selection skill for everyone, see together! Flanged gate valve selection technique has the following two points: 1, the structure and working principle of radiator flanged gate valve user indoor temperature control is accomplished by thermostatic radiator valves. By constant temperature controller thermostatic radiator valves, flow regulating valve, and a pair of fitting, which is the core component of constant temperature controller sensor unit, the bulb. Wen packages can be induced the change of ambient temperature and volume change, drive the regulator Industrial Valves core displacement, thus regulating the amount of water to change the radiator radiator heat. Flanged gate valve can set temperature adjustment, flanged gate valve will be in accordance with the requirements of setting the automatic control and adjustment of the radiator water, thus to achieve the goal of control indoor temperature. Flanged gate valve is generally installed in front of the radiator, by automatically adjust flow, realize the residents need to room temperature. Flanged gate valve has 2 flanged gate valve and tee flange gate valves. Tee flange gate valve is mainly used for single pipe system with cross tube, the shunt coefficient can be changed in the range of 0 ~ 100%, flow control room is big, but the price is more expensive, complicated structure. Two-way flanged gate valve for double pipe system, some for single pipe system. For double tube system of two-way flanged gate resistance; For single pipe system resistance is smaller. Flanged gate valve heat packs and general assembly into a whole body, thermal bag itself is the indoor temperature sensor. If you need, can use the remote temperature sensor; Remote temperature sensor in the required temperature control room, a part of the body in the heating system. 2, flanged gate valve gate valve type selection design of flange is one of the main heating system flow control adjusting device, other regulator is auxiliary equipment, so the flange gate is essential. If you don't set a heating system temperature control valve cannot say is called heat metering system. In the design of flange valve, the right selection is very important. Flanged gate valve selection purpose, it is according to the design flow rate ( Known under the heat load) To determine the KV value (pressure drop, allowing Flow coefficient) ; Then the KV value determine the diameter of the temperature control valve ( Model) 。 Therefore, sample design atlas or manufacturer must give KV values and the diameter of the relationship, or not convenient for designers to use. In flanged gate valve type selection design, is by no means a simple selection gate valve with pipe diameter flange is sufficient. But in the process of selection, flanged gate valve in the selected an ideal differential pressure working conditions. A flanged gate valves are normally working pressure difference between the 2 ~ 3 mh2o, no more than 6 ~ 10 largest mh2o. For this, be sure to give a flanged gate valve range value, to prevent noise, affect the normal work flanged gate valve. When under the same KV value, there are more than two kinds of caliber choice, should first choose the small caliber flange valve, its purpose is to improve the regulating performance of flanged gate valve.
