Reasonable use of control equipment ( 1)

balance pneumatic valve is actually a kind of pneumatic valve opening instruction manual adjustment. Balance the upstream and downstream end of the pneumatic valve and a pressure hole, look from the basic principle of regulation. Used to measure fluid pressure drop through the pneumatic valve. When using, measured the pneumatic valve pressure drop and read the opening, can be considered by the flow valves. Its function is equivalent to adjust the pneumatic valve and the combination of the equivalent orifice flow meter, make each branch of the flow distribution requirements. When the total cycle pump gear is run, the flow of the slip road ratio adhere to the same.

an effective energy saving heating system is equipped with the corresponding adjustment control equipment, & lt; An effective energy saving heating system is equipped with corresponding adjustment control equipment. If self-reliance type flow, differential pressure control of pneumatic valve, etc. As heating metering system reform, the indoor heating system after assembling pneumatic control valve piping properly equipped with control equipment is very important to this paper discusses the characteristics of the temperature control system before and after pneumatic valve assembly changes, pointed out that with the temperature control pneumatic valve properly equipped with control devices, as a guidance for the design and transformation.
the radiator temperature control pneumatic valve are required on the device. In the operation of the heating with the user to adjust the temperature control pneumatic valve, the reform of the heat metering heating system. District heat supply network flow changes from time to time. Flow rate become variable flow operation, adjustment of the initiative in the hands of users, and heating power company will not be able to predict and control the flow of the change. The temperature control of the pneumatic valve under the condition of variable flow operation, adjusting control device must be installed correctly talents play a role. Otherwise, can make the system not only can not meet the regulation requirements, sometimes counterproductive.


conditioning self-reliance type differential pressure control pneumatic valve

also do not need an external power, self-reliance type differential pressure control characteristics of pneumatic valve and self-reliance type pneumatic flow control valve is similar. Only depend on the characteristics of fluid flow and/or downstream on the resistance within a certain range of changes, can through the opening of the pressure variation in pipes adjust themselves to making the change of fluid pressure drop through the pneumatic valve core to make up for the change of pipeline resistance, the user's basic adhere to the constant inlet pressure difference.
self-reliance type flow control pneumatic valve

depend on the characteristics of fluid flow, the characteristics of the pneumatic valve is don't need an external power. And/or downstream on the resistance within a certain range of changes, can through the opening of the pressure variation in pipes adjust themselves to making basic stick to the same flow rate.
