The working principle of pneumatic valve pneumatic balance

static balance principle of the pneumatic valve is pneumatic pneumatic valve body of modulation, when the entrance pressure, take the initiative to reduce size, eliminate traffic change, and vice versa. If the reverse, the modulation system doesn't work. Modulation and the function of the pneumatic valve, there is a bias, reverse pressure and flow can be eliminated or even shut down.
since the resettlement pneumatic static balance pneumatic valve is to better heating, there is no the title. If is the outfit, is human error,
it will be correct. Pneumatic pneumatic valve belongs to static balance modulation field of pneumatic valve, its principle is by changing the clearance between the pneumatic valve seat and pneumatic valve core ( The opening) , change the flow resistance of fluid flows through the pneumatic valve, in order to target modulation traffic. Pneumatic valve pneumatic static balance of proportion in a local resistance can shift the throttling element, not the compressed fluid, the flow equation is available.
air static balance pneumatic valve strength:
more mobile, convenient use, engineering construction, engineering settlement stages completed or set equipment deployment stage using equilibrium will not affect the water system; Convenient change: when in some areas of the water system need to plan, will not affect the balance of water system planning and other areas.
and eliminate power consumption, with the balance of the whole water system, guaranteeing the refrigeration unit ( The economic, heat exchanger) And water pump with the best state of things running, with remarkable energy-saving results; Low wear and eliminate waste: due to the inability of guaranteeing water flow over the original plan, to ensure all set the durability of equipment deployment, stop the copper consumption caused by heavy traffic.
and progress quiet: because the water system of traffic equilibrium is active, to eliminate the artificial comminuted modulation about sex. For planning staff, reduce the amount of things, more mobile, reduced the amount of things: without a tedious resistance calculation of the whole pipeline and accelerating rate plan;
placed, throttling tube, the corresponding material and measurements, the balance of hydraulic system to the dynamic flow balance pneumatic valve to complete; Can stop due to the imbalance of water system and other many poor. Pneumatic valve important characteristic

(
the linear flow property in the pneumatic valve pressure difference before and after the stable environment, main flow and the opening on the linearly involvement;
( Have the accurate opening instructions
( Be handled by opening locking devices
the clerk means less arbitrarily change the opening; Table adjacent, easily performance before and after pneumatic valve differential pressure and flow pneumatic valve flow. Just balanced pneumatic valve has many advantages, but its application in air conditioning water system still exists many questions. If these questions deal with owe good, pneumatic static balance the characteristics of the pneumatic valve is not less than full display. Pneumatic static balance pneumatic valve is used for modulation system, various distribution point ( As each building block) Due to traffic. Every building at the entrance to the resettlement pneumatic valve, pneumatic static balance can make the total capacity of the heating system get reasonable allocation. The application

the operation of the pneumatic valve pneumatic static balance modulation modulation meet acceptance ( Is like a water pump variable speed modulation, etc. ) , we don't use pneumatic valve pneumatic static balance. Because of this modulation is implemented by changing the amount of water, thus modulation when changing the working condition of hydraulic system, with static balance is if use pneumatic pneumatic valve, pneumatic valve is bound to cause some to normal things, but the system flow rate is too large, Above the heat load of the flow at this time) Pneumatic valve fully open, some still can not meet the traffic demand, some pneumatic valve starting pressure difference because the two differential pressure can't get discouraged from less than normal things, namely appear traffic dispatch clutter. Obviously, due to the existence of balanced pneumatic valve meet the system modulation means less than. At this moment if accepted manual modulation pneumatic valve, system total flow, increase or decrease in proportion to the flow of each branch, each user can increase and decrease, namely the system meet the modulation can be conveyed to each end device.
when system running modulation for quality, and the modulation, can use pneumatic static balance pneumatic valve, pneumatic valve and independent type differential pressure balance due to the modulation method only change the water temperature, and has nothing to do with the working condition of hydraulic system, which in not working condition of the hydraulic shift system environment, the modulation transfer to each user and setting up the equipment deployment. Using the static balance pneumatic valve, pneumatic can learn network pressure bumps, maintain the accused of load flow is constant. Acceptance of balanced pneumatic valve can learn network pressure bump, and surrender the one ( Accused of internal loop resistance change) To maintain on accused of loop differential pressure constant.
when the system acceptance phases transition flow mass modulation, is each phase flow stability. But if use pneumatic valve, pneumatic static balance each flow stage to control the flow or pressure difference control setting, run very inconvenient, is unfavorable use.
