Life testing device for single-handle double-control water nozzle

Abstract

The invention relates to a sanitary-ware valve-switch-a device for nozzle performance testing. The single-handle double-control nozzle service life testing device comprises a vertical test-bed rack (1). The tested nozzle (G) is fixed in the middle of the rack (1), and is connected with the hot-water and cold-water inlet pipe (9); a lifting component which can move upward and downward is arranged above the rack (1), and the lifting component comprises a numerical-control electric motor (8) coupled with a lead-screw pair; the lifting device is arranged on the rotary disc (5) driven by a small numerical-control electric motor (6); and the two ends of a long connecting-rod (4) are connected with the nut and the grip block of the lead-screw pair by horizontal shaft pins (11, 12). The movement of the numerical-control electric motor (8) reduces and avoids the impact to the handle of the tested nozzle (G) and as well as the damage incurred thereto; the test result of the actual object is more objective and accurate, the test scope can cover a spherical surface larger than 180 degrees, and the test can be conducted under a comprehensive, accurate, precise and more real condition, and the automatic degree of the test is relatively high.

Description

(1) Technical field [0001] The invention relates to a performance testing device of a valve switch—a faucet, in particular to a life testing device for a single-handle double-control faucet whose temperature is controlled by a handle. (2) Background technology [0002] As known, in industrial production and daily life, a large number of valve switches—faucets are used everywhere. The traditional rotary faucets of the faucets control the size of the water by rotating the threaded faucet to open and close the small diameter of the faucet. Such a water tap is inconvenient to switch water, especially in many occasions it must be regulated separately by two hot and cold water taps to produce water at a suitable temperature. [0003] At present, the largest number of faucets are ceramic sealed faucets, which are divided into single-handle double-control and double-handle double-control. The main advantage of the ceramic sheet sealing faucet is that it has good sealing performance...

Problems solved by technology

But, also there is certain deficiency in the device of prior art

The main disadvantages are: ① The power of the test device in the prior art to move up and down is taken from the air pump. Although the air pump can move up and down in a straight line, the inertia and inertia of its reciprocating motion are relatively large, and the impact on the object under test is relatively large. The risk of affecting the test accuracy will cause gradual and subtle destructive damage to the measured object after impact, which will affect the product life; ②The operation is inconvenient. The device in the prior art can only provide the up and down movement of the faucet after it is clamped, but The single-handle double-control faucet moves in an approximately 180-degree upper and lower hemispherical range. Therefore, the faucet must be re-clamped every time the handle is changed to the left and right angles. The operation is troublesome and prone to omissions, which will affect the progress and accuracy of the test. Spend

③ As a product life test, each test cycle alternately performs centering, cold water, and hot water to comprehensively assess the adaptability of the faucet. For tens of thousands of tests, it should alternately perform centering, cold water, and hot water for tens of thousands of times. test, but the test device in the prior art can only do tens of thousands of hot water and centering tests after tens of thousands of cold water tests respectively, so the test method is unreasonable
