Automatic water injection and drainage device

Abstract

The invention discloses an automatic water injection and drainage device; a structure of the device comprises an exhaust hole, a water stop valve, a blowdown device, a water tank top cover, a water purification tank, a drainage pipe, a water sink base, a support base, a U-shaped water connection pipe, a water suction pump, a regulating pipe, a three-way water stopper, a connecting pipeline and a regulating valve; the middle part of the upper end of the support base is welded at the lower end of the water sink base; the upper end of the water sink base is arranged at the lower end of the waterpurification tank. The automatic water injection and drainage device has the beneficial effects that with addition of the blowdown device on the device, the device can automatically filter impuritiesin water while automatically doing water injection and drainage operation, so that the quality of testing equipment is protected, the impurities are discharged in time, the practicality of the deviceis ensured, the practical safety of the device is increased, the workload of the staff is also greatly reduced, and the device is practical.

Description

technical field [0001] The invention is an automatic water injection and drainage device, which belongs to the field of automatic mechanized detection and filtration. Background technique [0002] Automatic water injection and drainage equipment refers to a kind of mechanical equipment that can realize automatic water injection and drainage in mechanical equipment, so as to achieve the functionality of the test object in the test experiment. It is often used in clean water tanks, filter tanks and other equipment. [0003] In the prior art, when the equipment is performing automatic water injection and drainage equipment operations, it often uses its external tap water source, which cannot filter the impurities in the water source, which will easily lead to damage to its detection equipment. When there are many impurities in the water source or it is used for a long time In this case, it is not only easy to cause damage to the equipment, but also increases the workload of the...
