Problems solved by technology

[0006] There are a large number of imported products for the automatic flow balancing valve based on the second principle, but the flow control accuracy is generally low, the working pressure difference control range is poor, the application is not flexible, and most of the realization methods are based on the ideal single-orifice device. empirical method
[0007] At present, there is no known method for realizing the through hole of the control spool of an automatic flow balance valve with high-precision flow control function.

Embodiment Construction

[0035] With reference to the drawings, the present invention will be described in detail below.

[0036] The control valve core device of a high-precision automatic flow balance valve in this embodiment includes a flow control valve barrel 5, in which a flow control valve core 4 and a linear coil spring 6 are sequentially installed, and the flow control valve barrel 5 The tail end is connected with the compression cover 7; the flow control valve core 4 is hollow and can slide along the inner wall of the flow control valve barrel 5. It is provided with an inlet end surface fixing hole 1 and an inlet side flow fixing hole 2 for flow control The wall of the valve core 4 also has two side flow channels 3 with arc-shaped edges gradually enlarged along the fluid flow direction. There is an O-ring 8 on the outer edge of the tight cover 7, and the end of the flow control valve barrel 5 and the compression cover Between 7 is a threaded connection, a compression connection or a snap-fit ​​c...

Abstract

The inventive control spool means includes a flow control valve cylinder, in which are mounted one by one a flow control spool and a linear helical spring mounted. The flow control spool is hollow and it slides along the inner wall of the flow control valve cylinder. The method of manufacturing the control spool means includes the following steps of choosing the linear helical spring and setting the side-stream channel.

Description

Technical field [0001] The invention relates to a valve realization method and a valve, more specifically, to a control valve core device and a manufacturing method of a high-precision automatic flow balance valve. Background technique [0002] In the central air conditioning system of high-end buildings, the water pump and cooling tower equipment can save energy by 60% to 80% on average, and the refrigeration host can save energy by 10% to 40% on average. The energy saving potential of the building air conditioning system is huge. In the central air-conditioning water system pipe network, there is a common phenomenon of hydraulic imbalance. The hydraulic imbalance of the pipe network can easily cause the waste of system energy and increase the noise of equipment operation. The automatic flow balance valve is one of the best means to solve the hydraulic balance of the complex pipe network, and the comprehensive energy saving effect is about 10% to 45%. [0003] There are two real...
