Description
Technical field
The utility model is related to a kind of air conditioning system components, especially a kind of pressure measurement that performance is lifted by improving
Device, specifically a kind of improved idle call pressure tester.
Background technology
At present, air-conditioning box fillter section is matched somebody with somebody differential manometer and is mostly connected with casing using plastic flexible pipe.Because of plastic flexible pipe bore
It is larger, in pressure, it is vulnerable to the influence of air-conditioning box interior air-flow, so as to cause pressure differential detection value frequently to change, it is impossible to accurate measurement
Filter resistance.And, with the increase of service life, can turn to be yellow plastic flexible pipe embrittlement, not only unsightly, can also influence pressure difference
The service life of meter.Accordingly, it would be desirable to designing one kind can improve certainty of measurement, the pressure tester for increasing the service life.
Utility model content
The purpose of this utility model is directed to the deficiencies in the prior art, improves a kind of improved idle call pressure tester, can
To improve pressure measurement environment, differential pressure measurement precision is improved.
The technical solution of the utility model is：
A kind of improved idle call pressure tester, including differential manometer, the differential manometer are arranged in protective cover, the protective cover
It is fixedly mounted on air-conditioning boxboard, its top is provided with opening corresponding with the differential manometer dial plate；The pressure-measuring head of the differential manometer
It is connected with metal tracheae；The metal tracheae is arranged on air-conditioning boxboard by fixed seat, and its inlet end is imported in air-conditioning box；It is described
Metal tracheae inlet end port is provided with the current stabilization cover on the inside of air-conditioning boxboard.
Further, the differential manometer is arranged in the protective cover by several fixtures；Each fixture is L
Shape, its horizontal end is stuck in the bottom surface of the differential manometer, and long spiro nail is provided with its perpendicular end, can be from bottom to top be tightened in the protection
The top of cover, makes not contacted between the bottom surface of the differential manometer and air-conditioning boxboard.
Further, the fixed seat is cylindrical shape, and one end is provided with flange, can ecto-entad is firm is inlaid in
On air-conditioning boxboard；The internal diameter of the fixed seat is engaged with the metal tracheae, can closely be socketed in the metal gas
Guan Shang.
Further, the fixed seat is made up of rubber.
Further, the current stabilization cover is " caged ", and the inlet end of the metal tracheae can be completely covered；The current stabilization cover
On be uniformly arranged multiple size identical pod apertures, make enter metal tracheae air-flow more stable and uniform.
The beneficial effects of the utility model：
The utility model is reasonable in design, simple structure, easy to operate, can be effectively improved pressure measurement environment, makes pressure measurement gas
More uniform stabilization, it is to avoid the fluctuation of differential manometer pointer is excessive, improves differential pressure measurement precision.And, it is easy to safeguard, low cost
Honest and clean, outward appearance is neat and artistic.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1- differential manometers；2- protective covers；3- long spiro nails；4- fixtures；5- pressure-measuring heads；6- metal tracheaes；7- is fixed
Seat；8- air-conditioning boxboards；9- current stabilization covers.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of improved idle call pressure tester, including differential manometer 1.The differential manometer 1 is installed by several fixtures 4
In protective cover 2, and the protective cover 2 is fixedly mounted on air-conditioning boxboard 8, the differential manometer 1 is obtained firm installation.Institute
