Embodiment one
As shown in Figure 1-Figure 3, the present embodiment provides a kind of filter, which is installed on air-conditioning system pipeline 2.Such as
Shown in Fig. 1, filter 3 is connected on system pipeline 2 by shut-off valve 1.Filter 3 includes filter body 31 and is arranged in mistake
Filter screen 32 (referring to Fig. 3) inside filter body 31, the both ends of filter body 31 detachably connect with a shut-off valve 1 respectively
It connects, filter screen 32 takes the shape of a bag, and bag-shaped filter screen 32 can store more impurity, so that system pipeline 2 is not easy dirty stifled, extension
Cleaning frequency reduces wash number, reduces maintenance cost.
It particularly, can be not right in the present embodiment to weld, being detachably connected between shut-off valve 1 and system pipeline 2
Connection type between shut-off valve 1 and system pipeline 2 is further qualified, but shut-off valve 1 is detachably connected with filter 3,
Convenient for changeing and cleaning filter 3.
As shown in Figure 1, bend with 2 both ends of system pipeline that are connected of filter 3 that present embodiment provides, one end is to water
Square to extension, the other end extends to vertical direction.In the present embodiment, the direction of system pipeline 2 is not construed as limiting, only needing can
Refrigeration or heat-production functions are realized in other component cooperation with air-conditioning system.
Specifically, multiple stabilizer blades are arranged in interval on the lower surface of system pipeline 2, and multiple stabilizer blades play system pipeline 2
Supporting role.
As shown in Fig. 2, filter 3 further includes interconnecting piece 34, interconnecting piece 34 is in horn-like comprising big end and small end are small
End is connect with the end of filter body 31, and big end and shut-off valve 1 are detachably connected.Specifically, big end and 1 screw thread of shut-off valve connect
It connects, big end can cover on nut, and external screw thread is arranged in one end that shut-off valve 1 is connected with big end, match with the internal screw thread of nut.
Specifically, interconnecting piece 34 is metal tube, it is preferable that metal tube is copper pipe, and is welded on filter body 31.When
When needing to clean filter screen 32, the shut-off valve 1 being detachably connected with filter 3 is closed, interconnecting piece 34 can be with filter body
31 dismantle and clean together, do not need again all to bleed off the refrigerant in system pipeline 2, can clean filter screen 32, maintenance
Simplicity, maintenance cost is lower, improves maintenance efficiency.
Further, filter 3 further includes the flow direction mark 35 that 31 outer surface of filter body is arranged in, when seated,
Play the role of prompt to operator, is easily installed.
As shown in figure 3, filter body 31 is cylindrical, cavity is inside set, filter screen 32 is fixed in the cavity.Specifically
Ground, filter screen 32 include the open end and closed end being oppositely arranged, the flow direction of liquid, open end along filter body 31
Positioned at closed end upstream, this guarantees impurity to be stopped by filter screen 32, stays in impurity in filter screen 32.
