Abstract
The utility model discloses a differential gauge is got pressure equipment and is put, get the pressure head including differential gauge, protection casing, screw, mounting, metal joint, metal trachea and rubber, metal trachea one end pass through metal joint fixed mounting on the differential gauge, the other end inserts in rubber gets the pressure head, gets the non - shelves of pressure head mouthful about 10~15mm of end apart from rubber, rubber get the pressure head for the cylindric rubber body, one side is equipped with shelves mouthful, a shelves mouthful external diameter is greater than the external footpath of cylindric rubber, pressure head male box intralamellar part is got to rubber to stretch out 3~5mm of boxboard. Can be in the middle of air conditioning unit to move the process, the accurate filter fore -and -after pressure value that reads judges clearly and definitely whether the filter washs or change, and then the life of improvement filter and air conditioning unit's life cycle, and convenient for maintenance. Low cost, the outward appearance is neat and artistic.
Description
Technical field
The utility model relates to air-conditioning system, particularly relates to the differential manometer pressure obtaning device in a kind of air-conditioner filtering system.
Background technology
Current air-conditioning box differential manometer that fillter section is joined adopts plastic flexible pipe to be connected with box plate, because plastic flexible pipe bore is comparatively large, when pressure, is vulnerable to airflow influence in case, thus causes pressure differential detection value frequently to change, cannot Measurement accuracy filter resistance.And plastic flexible pipe is along with the increase of tenure of use, can turn to be yellow embrittlement, not only unsightly, affects the serviceable life of differential manometer.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind ofly can solves the device that the fluctuation of differential manometer pointer is large, improve pressure environment.
The technical scheme that the utility model adopts is: differential manometer pressure obtaning device, comprise differential manometer, protective cover, screw, fixture, metal joint, metal tracheae and rubber pressure head, described metal tracheae one end is fixedly mounted on differential manometer by metal joint, the other end inserts in rubber pressure head, distance rubber pressure non-shelves mouth end about 10 ~ 15mm; Described rubber pressure head is cylindric rubber bodies, and side is provided with shelves mouth, and shelves mouth external diameter is greater than cylindric rubber bodies external diameter, and it is inner that rubber pressure head inserts boxboard, and stretch out boxboard 3 ~ 5mm.
Described protective cover is installed on boxboard, and protective cover is provided with the hole corresponding with differential manometer dial plate.
Described differential manometer index dial card, outside protective cover, offsets with fixture bottom differential manometer.
Described screw is arranged on fixture, offsets inside screw-tipped and protective cover.
Compared with prior art, the beneficial effects of the utility model are: can in the middle of air-conditioner set operational process, read the force value before and after filtrator accurately, clearly judge whether filtrator cleans or change, and then improve the serviceable life of filtrator and the life cycle of air-conditioner set; Be convenient to safeguard; With low cost, outward appearance is neat and artistic.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated: differential manometer pressure obtaning device, comprise differential manometer 1, protective cover 2, screw 3, fixture 4, metal joint 5, metal tracheae 6 and rubber pressure 7, described metal tracheae 6 one end is fixedly mounted on differential manometer 1 by metal joint 5, the other end inserts in rubber pressure 7, and a distance rubber pressure 7 non-shelves mouth end are 10 ~ 15mm; Described rubber pressure 7 is cylindric rubber bodies, and side is provided with shelves mouth, and shelves mouth external diameter is greater than cylindric rubber bodies external diameter, and it is inner that boxboards 8 are inserted in rubber pressure 7, and to stretch out boxboard 8 be 3 ~ 5mm.
Described protective cover 2 is installed on boxboard 8, and protective cover 2 is provided with the hole corresponding with differential manometer 1 dial plate.
Described differential manometer 1 index dial card, outside protective cover 2, offsets with fixture 4 bottom differential manometer 1.
Described screw 3 is installed on the retainers 4, offsets inside screw 3 tip and protective cover 2.
Differential manometer pressure obtaning device uses protective cover 2 to be fixed by differential manometer 1, avoids unit operation to vibrate and to work the impact caused on differential manometer 1; Increase metal joint 5, increase the reliability of pressure; Metal tracheae 6 replaces traditional plastic flexible pipe, not easily occurs bending and dead folding, substantially increases the accuracy of differential manometer 1 numerical value; Rubber pressure 7 can greatly reduce the flow-disturbing that before and after filtrator, air-flow instability is brought.
Claims (3)
1. differential manometer pressure obtaning device, comprise differential manometer, protective cover, screw, fixture, metal joint, metal tracheae and rubber pressure head, it is characterized in that: described metal tracheae one end is fixedly mounted on differential manometer by metal joint, the other end inserts in rubber pressure head, distance rubber pressure non-shelves mouth end about 10 ~ 15mm; Described rubber pressure head is cylindric rubber bodies, and side is provided with shelves mouth, and shelves mouth external diameter is greater than cylindric rubber bodies external diameter, and it is inner that rubber pressure head inserts boxboard, and stretch out boxboard 3 ~ 5mm.
2. differential manometer pressure obtaning device according to claim 1, it is characterized in that: described protective cover is installed on boxboard, protective cover is provided with the hole corresponding with differential manometer dial plate.
3. differential manometer pressure obtaning device according to claim 1, is characterized in that: described screw is arranged on fixture, offsets inside screw-tipped and protective cover.
