Lower end that is interior and extending to housing, the contact travel switch the bottom for being separately positioned on sensory package, the terminals
Daughter board bends the two sides for being arranged on housing respectively.
In a preferred embodiment of the present invention, the quantity of the sensory package be 2, including low pressure sensory package and
High pressure sensory package.
In a preferred embodiment of the present invention, the sensory package includes sensing housing, pressure chamber, ring casing, pushes away
Bar, spring and flexible sheet, the pressure chamber are vertically set on the center in sensing housing, and the ring casing is horizontal
Be arranged on the bottom of sensing housing, the push rod is arranged on pressure chamber in and is located at the top of ring casing, the spring around
On push rod, the flexible sheet is horizontally set on the upper end of ring casing and positioned at the lower part of push rod.
In a preferred embodiment of the present invention, the sensing housing is in boss structure.
In a preferred embodiment of the present invention, the ring casing and flexible sheet are circular configuration.
In a preferred embodiment of the present invention, a diameter of 72-75mm of the ring casing；The flexible sheet it is straight
Footpath is 53-57mm.
The beneficial effects of the invention are as follows：The double-sensing pressure switch of the present invention, using double-sensing component, can control at the same time
Low pressure and high-pressure in air-conditioning refrigeration system, control accuracy are high, reduce refrigerant leakage, easy to assemble and more
Change, switch motion is reliable, high sensitivity, simple in structure, safe, service life length.

Embodiment
The technical solution in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only the part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this area is common
All other embodiment that technical staff is obtained without making creative work, belongs to the model that the present invention protects
Enclose.
As shown in Figure 1, the embodiment of the present invention includes：
A kind of double-sensing pressure switch, including housing 1, sensory package 2, contact travel switch 3 and terminal board 4, it is described
Sensory package 2 be separately positioned in housing 1 and extend to the lower end of housing 1, contact travel switch 3 is separately positioned on
The bottom of sensory package 2, the terminal board 4 bend the two sides for being arranged on housing 1 respectively.In above-mentioned, the biography
The quantity for feeling component 2 is 2, including low pressure sensory package and high pressure sensory package.
As shown in Fig. 2, the sensory package 2 includes sensing housing 21, pressure chamber 22, ring casing 23, push rod 24, spring
25 and flexible sheet 26, the pressure chamber 22 is vertically set on the center in sensing housing 21, the ring casing 23
The bottom of sensing housing 21 is horizontally set on, the push rod 24 is arranged in pressure chamber 22 and is located at the top of ring casing 23,
Around on push rod 24, the flexible sheet 26 is horizontally set on the upper end of ring casing 23 and is located at push rod 24 spring 25

Operation principle：The ownership of the low pressure sensory package control refrigerant of pressure switch, in refrigerant charging to necessarily
Switch connection ensures that the low pressure sensory package of refrigeration system is normally-open during pressure, compressor of air conditioner work, in refrigerant pressure
The high pressure sensory package control of pressure switch disconnects when rising to setting value, and compressor of air conditioner is stopped, and declines in refrigerant pressure
During to setting recovery pressure value, pressure switch control is connected, and compressor of air conditioner work, so controls compressor by pressure switch
Reciprocation cycle work reaches refrigeration effect.When refrigerant ownership deficiency or refrigerant leakage contribution refrigeration system normal work
When, the low pressure sensory package of pressure switch disconnects, and avoids refrigeration system from causing refrigeration system due to the ownership deficiency of refrigerant
Operation irregularity.
In conclusion the double-sensing pressure switch of the present invention, using double-sensing component, can control air conditioner refrigerating system at the same time
Low pressure and high-pressure in system, control accuracy is high, reduces refrigerant leakage, easy to assemble and replace, switch motion
Reliably, high sensitivity, simple in structure, safe, service life length.
