Problems solved by technology
Due to the large caliber of the plastic hose, it is easily affected by the airflow in the air conditioning box when taking pressure, which leads to frequent changes in the pressure difference detection value and cannot accurately measure the filter resistance
Moreover, as the service life increases, the plastic hose will turn yellow and become brittle, which is not only unsightly, but also affects the service life of the differential pressure gauge

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] Such as figure 1 shown.
[0016] An improved air-conditioning pressure measuring device includes a differential pressure gauge 1 . The differential pressure gauge 1 is installed in the protective cover 2 through several fixing parts 4, and the protective cover 2 is fixedly installed on the air-conditioning box panel 8, so that the differential pressure gauge 1 is installed stably. The top of the protective cover 2 is provided with an opening corresponding to the dial of the differential pressure gauge 1, so that the dial of the differential pressure gauge 1 can be securely installed on the opening, which is convenient for reading the indication of the differential pressure gauge 1. number. The fixing parts 4 are all L-shaped, and their horizontal ends are stuck on the bottom surface of the differential pressure gauge 1, and long screws 3 are a...

The invention relates to an improved air conditioner-used pressure measurement device, which comprises a differential pressure gauge. The differential pressure gauge is arranged in a protection cover, the protection cover is fixedly arranged on an air conditioner box plate, and the top end is provided with an opening corresponding to the differential pressure gauge dial; a pressure measurement head of the differential pressure gauge is connected with a metal air pipe; the metal air pipe is arranged on the air conditioner box plate through a fixing seat, and an air inlet end is guided to the air conditioner box; and the air inlet end port of the metal air pipe is provided with a steady flow cover arranged at the inner side of the air conditioner box plate. The design is reasonable; the structure is simple; the operation is convenient; the pressure measurement environment can be effectively improved; the pressure measurement air is more uniform and stable; large fluctuation of a pointer of the differential pressure gauge is avoided; the differential pressure measurement precision is improved; the maintenance is facilitated; the cost is low; and the appearance is tidy and attractive.
Description
technical field [0001] The invention relates to a component of an air-conditioning system, in particular to an improved pressure-measuring device with improved performance, in particular to an improved air-conditioning pressure-measuring device. Background technique [0002] At present, most of the differential pressure gauges equipped in the filter section of the air-conditioning box are connected with the box by plastic hoses. Due to the large caliber of the plastic hose, it is easily affected by the airflow in the air conditioning box when taking pressure, resulting in frequent changes in the pressure difference detection value, and it is impossible to accurately measure the filter resistance. Moreover, as the service life increases, the plastic hose will turn yellow and become brittle, which is not only unsightly, but also affects the service life of the differential pressure gauge. Therefore, it is necessary to design a pressure measuring device that can improve measur...
