Y-shaped filtering one-way check device of water supply pipeline

Abstract

The invention provides a Y-shaped filtering one-way check device of a water supply pipeline. The device comprises a filter provided with a water inlet structure and a water outlet structure, a filter screen is arranged on the water inlet structure of the filter, and an elastically movable one-way check valve element is arranged on the water outlet structure of the filter, so that the Y-shaped filter and a one-way check valve are combined into a whole. A water through hole is formed between the water inlet structure and the water outlet structure, the one-way check valve element is provided with a sealing piece corresponding to the water through hole, and the elastically movable one-way check valve element moves under the water flow pressure and opens the water through hole. When the elastically movable one-way check valve element capable is in a static state, the sealing piece seals the water passing hole under the elastic effect. The elastically movable one-way check valve element is arranged on the water outlet structure, so that one-way water supply is formed. The filter screen is arranged on the water inlet structure, so that the device has the characteristics of filtering and collecting impurities, cleaning the barrel and removing the impurities. The device can be used for a water supply pipeline and a water pipeline for air energy refrigeration and heating of an air conditioner.

Description

technical field [0001] The invention relates to a Y-type filter one-way check device, in particular to a Y-type filter one-way check device for a water supply pipeline. Background technique [0002] see Figure 4 , the original traditional one-way check valve 15 and the Y-type filter 18 are manufactured separately, not only need to use two sets of molds during production, but also need to be assembled, the one-way check valve 15 is installed at the water outlet of the Y-type filter 18 In addition, it also needs the cooperation of other pipeline parts, such as the connection between the one-way check valve 15 and the Y-type filter 18 through the connecting pipe 16 and the connecting elbow 17, resulting in an increase in volume, so there are high production costs and assembly problems. The problem of low efficiency. [0003] In addition, the Y-type filter and one-way check valve are combined into one structure, which has never appeared in waterway components. Therefore need ...
