Pneumatic valve flange gate selection skills

in recent years, with the development of national economy in our country, such as pneumatic valve flange gate pneumatic valve industry as an important part of mechanical equipment manufacturing industry, has a very important role. Pneumatic valve flange gate is widely used in industry, not only its influence in the field of civil has also been gradually expanding. Along with the below small make up to get to know the flange brake pneumatic valve selection skills.
flange brake pneumatic valve selection techniques mainly include the following two points:
, radiator flange brake the structure and working principle of pneumatic valve
user indoor temperature control is realized through the radiator thermostatic control pneumatic valve. Radiator thermostatic control pneumatic valve is made up of constant temperature controller, flow control of pneumatic 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 adjustment of pneumatic valve, pneumatic valve core displacement and adjust the amount of water to change radiator heat radiator. Pneumatic valve flange gate can set temperature adjustment, pneumatic valve flange gate 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. Pneumatic valve flange gate is generally installed in front of the radiator, by automatically adjust flow, realize the residents need to room temperature. Pneumatic valve flange gate has two-way pneumatic valve pneumatic valve flange gate and tee flange gate. Tee flange brake pneumatic valve is mainly used for single pipe system with cross tube, the shunt coefficient can be changed within the scope of the ~ %, flow control room is big, but the price is more expensive, complicated structure. Two-way pneumatic valve flange gate for double pipe system, some for single pipe system. For double tube system of two-way pneumatic valve flange gate resistance; For single pipe system resistance is smaller. Pneumatic valve flange gate heat pack with pneumatic valve general assembly into a whole, 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, pneumatic valve pneumatic valve body in a certain part of the heating system.
pneumatic valve, flange gate
flange type selection design of brake air flow control valve is a heating system regulation of the main equipment, other regulating pneumatic valve is auxiliary equipment, pneumatic valve flange gate is essential. If you don't set a heating system temperature control pneumatic valve cannot say is called heat metering system. In the design of pneumatic valve flange gate, the right selection is very important. Pneumatic valve flange gate selection purpose, it is according to the design flow rate ( Known heat load, the pressure drop allows to determine the KV value ( Flow coefficient; Then the KV value to determine the temperature control pneumatic valve diameter ( Models. Therefore, sample design atlas or manufacturer must give KV values and the diameter of the relationship, or not convenient for designers to use.
in the flange brake design, pneumatic valve selection is by no means a simple select pneumatic valve with pipe diameter of the flange gate is sufficient. But in the process of selection, pneumatic valve flange gate in the selected an ideal differential pressure working conditions. A pneumatic valve flange gate is usually work pressure difference between ~ mHO, best not more than ~ mHO. For this, be sure to give the range of the pre setting of the pneumatic valve flange gate, to prevent noise, affect the normal work of the pneumatic valve flange gate. When under the same KV value, there are more than two kinds of caliber choice, should first choose the small caliber flange brake pneumatic valve, its purpose is to improve the regulating performance of pneumatic valve flange gate.
