Description
Technical Field
The invention relates to a device for testing the tightness of a water path, in particular to a device for detecting the tightness of a water path with water blowing.
Background
Along with the supply of living standard of people, the requirement on the quality of drinking water is higher and higher, and more families are provided with water purifiers. The water purifier generally comprises a shell with a tap water inlet, a purified water outlet and a sewage outlet, wherein a plurality of water purifying tanks with filter elements are arranged in the shell, each purifying tank of the current latest purifier is provided with a three-hole joint, one hole in the middle is a water inlet, and two sides are respectively a waste water hole and a water purifying hole. Take three water purification jar as an example, the running water inlet passes through the inlet opening intercommunication of pipeline and first water purification jar, the waste water hole of first water purification jar and fourth water purification jar is through blockking up the shutoff, the clear water hole of first water purification jar divides into two the tunnel through the pipeline, respectively with the inlet opening intercommunication of second water purification jar and third water purification jar, the clear water hole of second water purification jar and third water purification jar passes through the inlet opening intercommunication with fourth water purification jar after the pipeline merges, the inlet opening of fourth water purification jar passes through the pipeline and communicates with the purified water delivery port of shell, the waste water hole of second water purification jar and third water purification jar passes through the pipeline and merges the back and communicates with the sewage delivery port of shell.
The quality of water purifier mainly embodies on the purifying effect who purifies jar, but whole water route leakproofness also is the important factor that influences the water purifier quality, need carry out the leakproofness to the inside water route of water purifier for this reason and detect, and general water pressure test all is manual structure, and three hole joints that use in the new product do not have self-locking structure, detect very inconvenient, can not inspect alone, need whole skeleton texture installation to accomplish the back just can detect, and the operation is very loaded down with trivial details. In addition, after the waterway tightness detection is completed, because the loop also contains test water, the waterway must be ensured not to contain water before the product is sold, so that a water blowing procedure is generally carried out after the waterway tightness detection, namely, the waterway detection and the water blowing are completed in two steps, and the test efficiency is greatly reduced.
How to design a section and can accomplish fast and detect the product and change to effectively carry out the leakproofness to the water purifier water route that takes three hole joints and detect, can also make the leakproofness detect and blow the device that the water process integrated together simultaneously, be the technical problem that technical staff in the field need solve.
