Multi-spool dynamic flow balance valve

Abstract

The invention provides a dynamic flow balance valve and particularly relates to a multi-spool dynamic flow balance valve. The multi-spool dynamic flow balance valve comprises an inlet valve body, an outlet valve body, a combined plate and a plurality of spool assemblies. The combined plate seal fixing clamp is arranged between the inlet valve body and the outlet valve body, and the spool assemblies respectively penetrate through the combined plate to be fixed to the combined plate in a seal mode. Each spool assembly is composed of a spool, a spool casing, a spring and a locking screw, the spool is provided with an end face fixing hole and a side flow channel with two symmetrical sides, the two sides of the side flow channel are symmetrical, the side flow channel comprises two evenly distributed fixed oval holes and two or four evenly distributed changeable holes, and the two fixing oval holes are communicated with two of the changeable holes in a one-to-one mode, wherein the two changeable holes are symmetrically distributed. The multi-spool dynamic flow balance valve can reduce stress imbalance in the side direction, flow uniformly passes, resistance is reduced, stability is improved, and the service life is prolonged. Meanwhile, the multi-spool dynamic flow balance valve is convenient to process and mange, capable of saving cost and convenient to assemble and disassemble.

Description

technical field [0001] The invention provides a dynamic flow balancing valve, in particular a multi-valve dynamic flow balancing valve. Background technique [0002] At present, a large number of dynamic flow balance valves cannot obtain a large flow dynamic flow balance valve because the opening of the valve core is limited by the size of the valve core. For the multi-spool dynamic flow balance valve, the spool used is a new structure spool formed by stamping, which is not conducive to the serial expansion and upgrade of the product. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a multi-spool dynamic flow balance valve in view of the defects in the prior art, the improved structure of which effectively overcomes all the existing problems described in the background art. [0004] The technical scheme adopted by the present invention to solve its technical problems is: [0005] A multi-valve dynamic flow balancing valve, comprising a...

Problems solved by technology

[0002] At present, a large number of dynamic flow balance valves cannot obtain large flow dynamic flow balance valves because the opening of the spool is limited by the size of the spool.

For the multi-spool dynamic flow balance valve, the spool used is a new structure spool formed by stamping, which is not conducive to the serial expansion and upgrading of products.
