Valve element service life tester of single-handle double-control water nozzle

Abstract

The invention provides a valve element service life tester of a single-handle double-control water nozzle, which belongs to the technical field of machinery and solves the problems of complicated structure, short service life, low testing precision, and the like of the traditional single-handle double-control water nozzle service life testing devices. The valve element service life tester of a single-handle double-control water nozzle comprises a testing table, and a positioning mechanism, a liquid supply system, a rotating mechanism and an executing mechanism are arranged on the testing table, wherein the positioning mechanism can position a workpiece; the liquid supply system is capable of providing testing water for the workpiece;and the executing mechanism which is connected with the valve element of the workpiece and can ensure that the workpiece yields water; the rotating mechanism drives the executing mechanism or the positioning mechanism to rotate to a plurality of set testing angles and / or rotate within a set testing angle range; and when the executing mechanism rotates at the set testing angle and / or within the set testing angle range, the workpiece can yield water. Theinvention has the advantages of simple structure, convenient operation, high testing precision, and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a valve core life testing machine, in particular to a valve core life testing machine with single handle and double control faucets. Background technique [0002] The single-handle double-control faucet is connected with cold water pipes and hot water pipes. When in use, the water temperature can be adjusted by turning the left and right angles of the single handle, and the water flow can be controlled by turning the up and down angles of the single handle. It is very convenient to use. Therefore, the single-handle double-control faucet is widely used in daily life. [0003] The single-handle double-control faucet has strict indicators and must be tested before leaving the factory. Among many testing items, the detection of the life of the single-handle double-control faucet spool is a key point. In order to make the detection of the life of the single-handle double-control fauc...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned single-handle double-control faucet life test device can cycle through the tests of centering, cold water, and hot water, its structure is relatively complicated. After being used for a period of time in an environment with water, the screw pair, rotating disc and interlocking screw pair are prone to rust, and the service life is short

Moreover, only the three positions where the spool is located at the end points on both sides and the center position are tested, the test range is small, and there is still a lack of intermediate links in the test, that is, the lack of a link in which the single handle rotates to discharge water when it is open, and the test accuracy and effect are not ideal.
