Description

Backpulsing non-resistance filter

Technical field

The utility model relates to air-conditioning technical fields, refer in particular to backpulsing non-resistance filter.

Background technique

The small-sized y-type filter of the y-type filter of existing idle call, especially end, flow is big, cleaning trouble, recoils When resistance it is big.

Summary of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art, provide it is a kind of it is structurally reasonable, using effect is good Backpulsing non-resistance filter.

To achieve the above object, technical solution provided by the utility model are as follows: backpulsing non-resistance filter, it includes There is water inlet pipe and be mounted on into the inlet valve on water water inlet tube direction, filtering is installed on the water inlet pipe of inlet valve water discharging direction Case, Rose Box are rectangle, and length direction bottom is downwardly extending the collecting sewage room of up big and down small trapezoidal shape, collecting sewage room bottom It is equipped with blowdown valve at portion center, is equipped with filter plate in collecting sewage room, filter plate one end is connect with collecting sewage room's water discharging direction bottom, another End connect with the Rose Box above collecting sewage room's water inlet direction, and filter plate main bent part is at wavy, and wavy top of the waves is positioned at collecting Dirty room water inlet direction and water discharging direction are evenly distributed with filter hole in filter plate main body.

The Rose Box both ends are equipped with connecting flange, and are connected on water inlet pipe by connecting flange.

Using being tightly connected between the filter plate edge and Rose Box, collecting sewage room, junction passes through stainless steel Item is reinforced.

For the utility model after adopting the above scheme, water inlet pipe connects air-conditioning water supply line, and Rose Box water discharging direction connects air-conditioning Water return pipeline closes inlet valve after adopting the above scheme, opens blowdown valve, and sundries is automatically drained out with sewage, can be in blowdown valve On connect rubber hose, sewage is discharged into bucket, it is ensured that sanitary conditions；Filter plate main bent part angle is 60 , wavy by being converted into Filter plate, can effectively increase filter area, than traditional y-type filter sectional area increase by more than ten times (different tube diameters are slightly not Together), and since filter plate is tilted to water inlet direction, the water in air-conditioning water return pipeline can substantially accomplish non-resistance in recoil Press to filter hole, it is counter to filter hole to be cleaned, be effectively reduced filter recoil resistance；It is closed using the structure after this programme Reason, using effect are good.

Detailed description of the invention

Fig. 1 is the overall structure diagram of the utility model.

Fig. 2 is the installation schematic illustration of the utility model.

Specific embodiment

Below with reference to all attached drawings, the utility model is described in further detail, the preferred embodiment of the utility model are as follows: ginseng See attached drawing 1 and attached drawing 2, backpulsing non-resistance filter described in the present embodiment includes water inlet pipe 1 and is mounted on water inlet pipe 1 The inlet valve 2 intake on direction is equipped with Rose Box 3 on the water inlet pipe 1 of 2 water discharging direction of inlet valve, and 3 both ends of Rose Box, which are equipped with, to be connected Acting flange, and be connected on water inlet pipe 1 by connecting flange, Rose Box 3 is rectangle, and length direction bottom extends downwardly shape At the collecting sewage room 4 of up big and down small trapezoidal shape, 4 bottom center of collecting sewage room is equipped with blowdown valve 6, is equipped with filter plate in collecting sewage room 4 5,5 one end of filter plate is connect with 4 water discharging direction bottom of collecting sewage room, and the Rose Box 3 above the other end and the water inlet of collecting sewage room 4 direction connects It connects, 5 main bent part of filter plate is at wavy, and wavy top of the waves is located at collecting sewage room 4 and intakes direction and water discharging direction, filter plate 5 It is evenly distributed with filter hole in main body, using being tightly connected between 5 edge of filter plate and Rose Box 3, collecting sewage room 4, connects Place is reinforced by stainless steel strip.The water inlet pipe of the present embodiment connects air-conditioning water supply line, and Rose Box water discharging direction connects air-conditioning return pipe Inlet valve is closed after above-described embodiment in road, opens blowdown valve, and sundries is automatically drained out with sewage, can connect on blowdown valve Rubber hose, sewage are discharged into bucket, it is ensured that sanitary conditions；Filter plate main bent part angle is 60 , by being converted into wavy mistake Filter plate can effectively increase filter area, increase by more than ten times (different tube diameters are slightly different) than traditional y-type filter sectional area, And since filter plate is tilted to water inlet direction, the water in air-conditioning water return pipeline can substantially accomplish unresisted pressure in recoil It is counter to filter hole to be cleaned to filter hole, filter recoil resistance is effectively reduced；Using after the present embodiment it is structurally reasonable, Using effect is good.

The embodiment of the above is only the preferred embodiment of the utility model, and the reality of the utility model is not limited with this It applies range, therefore all shapes according to the utility model, changes made by principle, should all cover in the protection scope of the utility model It is interior.
