Manual balance pneumatic valve working principle and key points for installation

manual balance pneumatic valve is a kind of pneumatic valve with special functions, has good flow characteristic, can reasonable distribution of flow, implementation flow quantitatively, can effectively solve the heating ( Room temperature cold hot uneven problems that exist in the air conditioning system. Opening locking devices and a small pneumatic valve used for flow measurement of pressure, so as long as in the selection and the user entry on the balance of the appropriate specifications pneumatic valve, with special intelligent instrument for the disposable lock after debugging, the system of the total water control in a reasonable range, which can overcome the 'big flow, small temperature difference is not reasonable phenomenon'.

manual balanced pneumatic valve is one-time manual regulation, can not automatically changes over system working condition of drag coefficient, so that the static balance pneumatic valve. Manual balance is the object of the pneumatic valve role resistance, can have the effect of manually adjustable orifice, the resistance of pipeline system is to balance, reach the role of each loop resistance balance. Can solve the problem of steady state misadjustment of system: when the operation condition is different from design conditions, circulating water is more than or less than the design conditions, as a result of the balancing pneumatic valve is system resistance, to the distribution of the new water proportion according to the design and calculation of balance, make the flow of the slip road will be in proportion to increase or decrease at the same time, still meet corresponds to the current load flow requirements.

pneumatic valve installation manual balance point

. Balance pneumatic valve can be installed on the way back to the water pipe, also can be installed on the pipes. Such as system pressure can meet the requirements, it is suggested that will balance the pneumatic valve installed on the way of return pipe of water temperature is low.
　　
　　. Pneumatic valve can be installed in horizontal balance, also can be installed vertically.
　　
　　. The opening on the handle indicates digital should be toward the orientation of the debugging personnel can see, with convenient operation. Joint on measurement of pneumatic valve body before should not have obstacles, in order to avoid unable to connect to debug instrument when debugging. When installed in the ceiling, should make the direction of the handle down.
　　
　　. Straight pipe installation location to set according to requirements of the equipment, often times the pipe diameter.
　　
　　. Should not arbitrarily change the pneumatic valve opening balance. The balance of pipe network system installation pneumatic valve after debugging, to maintain the balance of the system state, in the process of system normal operation, should not arbitrarily change the balance of pneumatic valve opening, especially should not change the opening the lock.
