New valve - dynamic resistance balance set of three valves function, jktl valve patented product
Dynamic resistance balance valve
Dynamic resistance balance valve is my company's patented product (national patent number: 200920163405.1), which can automatically eliminate the congestion and constant user pressure, absorption of external network pressure fluctuations, support the controlled system independent adjustment; differential calibration accuracy and precision adjustment.High; control the front of the catheter to install the cut-off valve, control the pressure adjustable range, easy disassembly.

Dynamic resistance balance valve function:
Dynamic resistance balance valve has three functions: self-flow valve function, manual balance valve function, self-pressure valve function. Respectively, to achieve the three different operating mode pump conversion. Constant flow operation with self-flow valve function.When the variable is running, the manual balancing valve function is used. When the user is running, the variable flow is converted into the self-operated differential pressure valve function. To avoid frequent replacement of the hot spring valve, reducing heating costs.

Dynamic Resistance Balancing Valve Product Overview:
In the central air conditioning and heating system, with the frequency conversion technology, temperature control technology and other energy-saving technology applications and the implementation of household heat metering, so that the operation of the pipe network system has produced a great difference.The selection is also very different, such as the use of errors can not achieve the desired effect. Uncertainty of the operating mode has created uncertainty about the selection of hydraulic balance products. This market situation forces the balance valve manufacturer to the existing balance valve product.To carry out technological innovation, so that the balance valve products with versatility and multi-purpose to meet market demand.

Dynamic resistance balance valve function:
Dynamic resistance balance valve has three functions: self-flow valve function, manual balance valve function, self-pressure valve function. Respectively, to achieve the three different operating mode pump conversion. Constant flow operation with self-flow valve function.
When the variable is running, the manual balancing valve function is used. When the user is running, the variable flow is converted into the self-operated differential pressure valve function. Can be converted according to the operating mode into different functions, to avoid the system due to changes in operating mode and replace the valve, but also solve the purchasing side because of the wrong choice of balance valve so that the system can not play the desired effect and other series of problems while reducing heating costs.

Dynamic resistance balance valve installation Note:
1, before the installation of the need for hydraulic balance calculation of the pipe network, the pressure is not enough or the end of the user and the heating effect is not good User is strictly prohibited to install, after installation may cause the user to heat the effect is more bad;
2, the valve does not have the ability to shut down, can not be used when the truncated valve;
3, not from the return pipe water, flushing pipes and pressure;
4, the heat period without heat, should be full of water maintenance pipelines and valves;
5, this valve can not solve the problem caused by pipeline blockage;
6, the use of manual balance valve function, the user should be adjusted by the design flow, and the system pressure, the same flow, and then one by one (lock switch) into a manual balance valve function, do not tune a lock a use of dynamic resistance balance valve:
In the initial stage of the heating network, the locking device is fully opened. The valve is adjusted according to the adjustment method of the self-operated flow control valve. The flow of the hot user reaches the equilibrium state quickly, and the self-operated flow control valve is played on the heat balance control Advantage. then the locking device is actuated and the valve becomes a static balance valve with variable flow performance. As the various hot users balance, and the circulation pump and then change the flow control, the user traffic will be equal to the proportion of changes, still maintain a balanced state.

Flow control valve constant flow and static balance valve variable flow, two functions can be converted according to specific needs. Household metering, connected to the pressure tube can be used as a self-pressure differential control valve.
