Description
Technical field
The present invention relates to a kind of air conditioning system components, especially a kind of pressure measurement for lifting performance through improving are filled
Put, specifically a kind of improved idle call pressure tester.
Background technology
At present, the matched somebody with somebody differential manometer of air-conditioning box fillter section 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 impact of air-conditioning box interior air-flow, so as to cause pressure differential detection value frequently to change, it is impossible to accurately measure
Filter resistance.And, with the increase of service life, can turn to be yellow plastic flexible pipe embrittlement, not only unsightly, can also affect pressure reduction
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.
The content of the invention
The purpose of the present invention is, for the deficiencies in the prior art, to improve a kind of improved idle call pressure tester, Ke Yigai
Kind pressure measurement environment, improves differential pressure measurement precision.
The technical scheme is that：
A kind of improved idle call pressure tester, including differential manometer, the differential manometer are arranged in protective cover, and the protective cover is fixed
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 and gold
Category trachea is connected；The metal trachea is arranged on air-conditioning boxboard by fixed seat, and its inlet end is imported in air-conditioning box；The metal
Trachea 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 are stuck in the bottom surface of the differential manometer, are provided with long spiro nail in its perpendicular end, can be from bottom to top be tightened in the protection
The top of cover, makes not contact 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 so as to can ecto-entad is firm is inlaid in
On air-conditioning boxboard；The internal diameter of the fixed seat is engaged with the metal trachea so as to 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 trachea can be completely covered；The current stabilization cover
On be uniformly arranged multiple size identical pod apertures, make the air-flow more stable and uniform into metal trachea.
Beneficial effects of the present invention：
Reasonable in design, simple structure of the invention, it is easy to operate, pressure measurement environment can be effectively improved, makes pressure measurement gas more uniform
With it is stable, it is to avoid the fluctuation of differential manometer pointer is excessive, improves differential pressure measurement precision.And, it is easy to safeguard, with low cost, outward appearance is whole
It is clean attractive in appearance.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein：1- differential manometers；2- protective covers；3- long spiro nails；4- fixtures；5- pressure-measuring heads；6- metal tracheas；7- is fixed
