Embodiment Construction

[0019] see figure 1 , figure 2 and image 3 , the balance valve test platform provided by the present invention designs corresponding passages for balance valves of different calibers, and only needs to replace the balance valve during detection, which is not only conducive to stabilizing the test results of the balance valve, but also reduces the labor intensity of the staff, and the The test platform can realize the automatic control of the balance valve test, which is more conducive to stabilizing the test results and avoiding the occurrence of large deviations.

[0020] The test platform includes a test circuit. The test circuit is mainly composed of a water tank g connected in series through water pipes, a pressure-stabilizing water pump c, a flow detection pipeline and a balance valve interface unit. The balance valve interface unit is composed of one or more The balance valve interface branch is composed of a balance valve interface f and pressure detection instrumen...

Abstract

The invention relates to a test platform of a balance valve, which comprises a test loop, wherein the test loop mainly comprises a water tank, a pressure stabilizing water pump, a flow detecting pipeline and a balance valve interface unit which are connected in series by water pipes; the balance valve interface unit comprises one or more balance valve interface branches; each balance valve interface branch is provided with a balance valve interface and a pressure detecting instrument for detecting a pressure difference at both ends of the balance valve interface; the balance valve interface branches are connected in parallel; and all the balance valve interfaces have same or different connecting structures. The platform realizes a detecting test of the balance valves with different diameters, is convenient for the detection of the balance valve and can also carry out automatic control by a control device, have stable detecting result and small offset and improve the detecting efficiency.

Description

technical field [0001] The invention relates to a balance valve test platform, which belongs to the technical field of machinery. Background technique [0002] The detection of the balance valve can be done by the formula (Where, Q is the flow rate of water passing through the balance valve, ΔP is the pressure difference at the inlet and outlet of the balance valve) Calculate the KV value, and compare the calculation result with the standard value, so as to judge whether the balance valve is qualified. At present, the collection of Q and ΔP and the analysis of KV values ​​are mostly done manually. It is inconvenient to replace the balance valve, and the test conditions basically rely on manual operation, which has not yet achieved automatic adjustment. Low efficiency and inconvenient operation. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention provides a balance valve test platform, in which the corresponding pas...
