Abstract
The utility model discloses a filter with a pressure difference monitoring function. The filter comprises a shell, a filter screen arranged in the shell and a differential pressure gauge, wherein the shell comprises a first through hole and a second through hole, one end of the second through hole is communicated with the first through hole, the other end of the second through hole is provided with a third flange, a sealing flange is arranged on the end surface of the third flange, the filter screen is arranged in the second through hole, a first pressure tapping hole is formed at the position of the inlet of the first through hole, a second pressure tapping hole is formed at the position of the outlet of the first through hole, one end of the differential pressure gauge is connected with the first pressure tapping hole and the other end of the differential pressure gauge is connected with the second pressure tapping hole. The filter has simple structure and convenience in use, the filter screen can be conveniently replaced, and the difference value of pressures of the inlet and the outlet of the filter can be directly monitored, so as to replace the filter screen timely and ensure the pipeline to be smooth.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of filter with pressure reduction monitoring.
Background technology
Filter is mounted in device conventional on pipeline, because long-time use can be at filter interior meeting accumulated impurity, now just need to pull down filter and carry out cleaning and filtering net, first unloading process turn-offs the ball valve of upstream, need the medium of downstream line inside all to emit simultaneously, and then the bolt of Fixed-Filter is all disassembled, take out filter webs, after cleaning filter net, also need to reinstall up, complex steps, need to spend a large amount of manpowers and time, efficiency is very low.
Because screen pack is that sealing is arranged on pipe interior, can not directly observe filter interior impurity situation simultaneously, cannot accurately judge the opportunity of cleaning and filtering net, use also very inconvenient.
Utility model content
The purpose of this utility model is: in order to address the above problem, a kind of filter with pressure reduction monitoring simple in structure, easy to use is provided, and it can be convenient for changing screen pack, simultaneously again can direct-detection filter inlet outlet pressure differential value, thereby change in time filter screen, guarantee the smoothness of pipeline.
To achieve these goals, the technical solution of the utility model is:
With a filter for pressure reduction monitoring, comprise housing, be arranged on filter screen, differential manometer in described housing; Described housing comprises the first through hole and the second through hole; One end of described the second through hole and the first through hole are connected; The other end arranges three-flange; Described three-flange end face is provided with sealing flange; Described filter screen arranges in the second through hole; Described the first through hole import department is provided with the first pressure tappings; Described the first through hole exit is provided with the second pressure tappings; Described differential manometer one end connects the first pressure tappings, and the other end connects the second pressure tappings.
Further; Described sealing flange is provided with ball valve.
Further; Described sealing flange is bolted to connection with filtration flange.
Further; Described the first through hole import arranges the first flange, and outlet arranges the second flange.
The utility model is owing to having adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
The utility model, owing to being provided with differential manometer on filter, can detect the pressure difference of filter inlet and outlet in real time, thereby grasps filter net jam situation, can clean in time or change filter screen; The utility model is owing to being arranged on filter screen in the second through hole, and without filter entirety is dismantled from pipeline, only need open sealing flange just can clean or change filter screen, very convenient quick.The utility model, owing to being provided with ball valve on sealing flange, can directly eject the impurity in screen pack; The utility model, because the import at filter and outlet are provided with flange, can conveniently be connected with other equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model with the filter of pressure reduction monitoring.
The specific embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of filter with pressure reduction monitoring, comprises housing 1, is arranged on filter screen 2, differential manometer 3 in described housing 1; Described housing 1 comprises the first through hole 11 and the second through hole 12; One end of described the second through hole 12 and the first through hole 11 are connected; The other end arranges three-flange 121; Described three-flange 121 end faces are provided with sealing flange 4; Described filter screen 2 arranges in the second through hole 12; Described the first through hole 11 import departments are provided with the first pressure tappings 113; Described the first through hole 11 exits are provided with the second pressure tappings 114; Described differential manometer 3 one end connect the first pressure tappings 113, and the other end connects the second pressure tappings 114; Owing to being provided with differential manometer 3, can detect in real time the pressure difference of filter inlet and outlet, thereby grasp filter screen 2 stopping states, can clean in time or change filter screen 2; Owing to filter screen 2 being arranged in the second through hole 12, without filter entirety is dismantled from pipeline, only need open sealing flange 4 just can clean or change filter screen 2, very convenient quick.
Preferably, described sealing flange 4 is provided with ball valve 5; Can directly the impurity in filter screen 2 be ejected, convenient and swift.
Preferably, described sealing flange 4 is bolted to connection with filtration flange 121.
Preferably, described the first through hole 11 imports arrange the first flange 111, and outlet arranges the second flange 112, are conveniently connected with other equipment.
In sum, the utility model is simple in structure, easy to use, can be convenient for changing screen pack, can directly monitor again filter inlet outlet pressure differential value, thereby change in time filter screen simultaneously, guarantees the smoothness of pipeline.
