Abstract
The utility model discloses a kind of devices for detecting air-conditioning system pressure, including ontology and pressure sensing cell, wherein, the body interior is hollow, is provided at both ends with threaded area, and middle part has pressure detecting area, the pressure detecting area is connected to the hollow portion of ontology, and is provided with internal thread；The sleeve that pressure sensing cell includes one end to be spirally connected with pressure detecting area, the plunger being mounted in sleeve, and it is socketed in first spring and second spring at plunger both ends respectively；One end of plunger extends to the outside of sleeve.Tested test system is jacked up plunger when system under test (SUT) contains pressure by importing and exporting cut-in pressure detection device, and user can have found.When gas is evacuated in system, formation negative pressure, plunger is sucked inwards, can be found by one outside plunger flexible situation.
Description
Technical field
The utility model is related to refrigerant reclaiming device, especially a kind of devices for detecting air-conditioning system pressure.
Background technology
Currently, in the market without it is a be specifically used to detection air-conditioning system in whether the device containing refrigerant.General family
There is no pressure gauge that can not be explicitly shown system situation with pressure with air-conditioning, can not judge whether contain refrigerant in air-conditioning system,
If opened rashly it is not possible to that the gas in air-conditioning system can be caused to spill into air, pollutes air.
Utility model content
Purpose of utility model：A kind of device for detecting air-conditioning system pressure is provided, it is of the existing technology to solve
Problem inconvenient for use.
Technical solution：A kind of device for detecting air-conditioning system pressure, including：
Ontology, the body interior is hollow, is provided at both ends with threaded area, and middle part has pressure detecting area, the pressure detecting area
It is connected to the hollow portion of ontology, and is provided with internal thread；
Pressure sensing cell, including sleeve that one end and pressure detecting area are spirally connected, the plunger being mounted in sleeve, and
It is socketed in first spring and second spring at plunger both ends respectively；One end of plunger extends to the outside of sleeve.
In a further embodiment, the plunger is equipped with sealing ring, close between plunger and sleeve to reinforce
Seal effect.The sleeve is provided with sealing material with pressure detecting area junction.Block protrusion is provided on the ontology.It is described
Plunger extends to the part outside sleeve and several scales is arranged.
Advantageous effect：Tested test system is by importing and exporting cut-in pressure detection device, will when system under test (SUT) contains pressure
Plunger jacks up, and user can have found.When gas is evacuated in system, formation negative pressure, plunger is sucked inwards, passes through circle
One flexible situation can be found outside plunger.It can easily detect whether to contain refrigerant in system under test (SUT) or know
No is vacuum state.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, the device for detecting air-conditioning system pressure of the utility model includes mainly device body 5 and pressure
Power detection unit.Wherein, pressure sensing cell includes mainly sleeve, the first spring 1, plunger 2 and second spring 3.
One end of plunger extends to the outside of sleeve, forms a pressure indication end 4.It can be seen that device body is
There is gas-liquid channel 56, both ends to be respectively arranged with ramp shaped guide portion 53, threaded portion 55 and block protrusion for one hollow tubular, inside
54.Middle part is pressure detecting area 51, which is connected to gas-liquid channel, and is provided with female threaded joint 52.Ramp shaped guide portion is just
It is operated in grafting.Convenient for fixing in the duct, block protrusion is hexangle type, and bonding pad can not only be prevented long for threaded area, and
Convenient for detection device was mounted in communicating pipe with spanner.The spiral shell of both ends screw thread is to preferably reversed simultaneously, it is only necessary to same
Direction rotates the detection device, you can completes connection, is managed without being rotatablely connected.
Plunger extends cartridge exterior, and the pressure indication end of formation can mark off several regions, put on based on experience value
Scale, further can quantitatively indicate the size of pressure at the case where substantially showing pressure.
The operation principle of this programme is as follows：By two sections of spring clips among plunger, since there is spring pressure at both ends,
Plunger is maintained at centre and will not be jacked up by one side, and when the system access present apparatus, bullet can be squeezed if the decorum is with pressure
Spring, spring jack up plunger, and one of plunger will emerge, and whether staff, that is, can be known system carries pressure.
When the gas in system is evacuated, for other side spring because being evacuated stress stretching in system, plunger is inside, and work people
Member may know that gas has been evacuated in this thing system, no longer contains gas.Reach and is just understood without the external mode of pressure gauge
Whether contain gas in road system.
In short, stress balance of this pressure-detecting device by spring and plunger, gas presses to plunger in system
Keep it flexible, convenient for whether containing gas in staff's discovery system.
Preferred embodiments of the present invention, still, the utility model and unlimited are described in detail above in association with attached drawing
Detail in the above embodiment can be to the skill of the utility model in the range of the technology design of the utility model
Art scheme carries out a variety of equivalents, these equivalents belong to the scope of protection of the utility model.
