Embodiment Construction
[0046] The content of the invention is further described in detail below in combination with the accompanying drawings and specific embodiments:
[0047] The utility model relates to an access type pressure detection and control equipment, which comprises a shell, a first air hand valve, a second air hand valve, a first pressure gauge, a second pressure gauge and various connectors for connection. Installation method, such as Figure 1 and Figure 2 The working principle is shown in Figure 3 As shown in.
[0048] The shell is a cuboid, and a cover plate on it can be opened by sliding. All parts and components are connected by conduit. The main pipe is air inlet 4 - first air hand valve 3 - air outlet 5. The first pressure gauge 8 is connected between air inlet 4 and first air hand valve 3, the second pressure gauge 9 and second air hand valve 6 are connected between first air hand valve 3 and air outlet 5, and a conduit is connected at the other end to the atmosphere. The first air ...

The invention provides access type pressure detection and control equipment and method, and aims to solve the problems that the integrity of a cold air system needs to be damaged and the deflation force is difficult to control when the pressure of the system is released in an existing cold air system test. The equipment comprises a shell, a first gas hand valve, a second gas hand valve, a first pressure gauge and a second pressure gauge, wherein the first gas hand valve and the second gas hand valve are positioned on the shell; the shell is further provided with an air inlet, an air outlet and an exhaust port. Gas enters the first gas hand valve through the gas inlet and then is discharged from the gas outlet, namely the main pipeline is gas inlet-gas hand valve-gas outlet; a first pressure gauge is connected between the gas inlet and the first gas hand valve; a second pressure gauge and a second gas hand valve are connected between the first gas hand valve and the gas outlet; and the other port of the second gas hand valve is communicated with the exhaust port.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning system test, in particular to an access pressure detection and control equipment and method, which can be used for the detection and regulation of pressure in the system during aircraft air-conditioning system test. Background technology [0002] Generally, in aircraft repair, air tightness and functional testing of the air-conditioning system are required to ensure the reliability of the air-conditioning system. These tests require the pressure of the system to be within a certain range, so it is necessary to detect and control the pressure of the system. At present, only the ground inflation equipment is used to provide pressure for the inflation of the aircraft air conditioning system, and the pressure in the system is reflected by the pressure gauge on the ground inflation equipment. The aircraft air-conditioning system is generally composed of pressure storage bottle (i.e. cold cylinder),...
