Abstract
The utility model discloses a taper sealing discharging valve with the structure including a valve body, a regulation nut, a spring, a positioning seat, a valve core, an inlet tube and an outlet tube; wherein, the valve body is in a cylindrical shape with the front end shrunk into an air inlet; the side wall of the valve body is provided with an air outlet; the air inlet and air outlet are respectively welded with the air inlet tube and the air outlet tube with silver; the cavity of the valve body is provided with a valve plug, the positioning seat and the spring in order which are controlled by the regulation nut and sealed through a cap arranged at the back end of the valve body. Therefore, when the discharging pressure of the air conditioning compressor exceeds a certain value, the stress of valve plug is larger than the flexible force of spring, and the valve plug ejects the air inlet, thus the spring is compressed to ensure the air inlet and air outlet communicated with each other, then the load is discharged, the compressor recovers a normal work, the flexible force is larger than the discharging pressure of the compressor, the valve plug return with the spring and seal the air inlet, thereby maintaining a normal pressure inside the maintenance system and avoiding overload operation of the compressor. The taper sealing discharging valve of the utility model has the advantages of a simple structure, good work reliability and low manufacturing cost.
Description
The utility model relates to a kind of regulating valve, is specially adapted to the automatic adjusting of air conditioner with bypass pressure.
The present air conditioner by-pass and pressure regulator valve that uses, two joints were welded about valve body adopted on the one hand, at weld circular film is set, diaphragm contacts with spool, opens spool by the displacement of diaphragm central compression, adopts suction port to be arranged on valve body chamber sidewall direction on the one hand, the air outlet is arranged on port, can satisfy the index request that uses on such design function, but have following shortcoming in actual mechanical process: 1, the welding diaphragm is cumbersome and complicated, the scrappage height; 2, employed spillage of material is many; 3, cost of production height.
The art designs content of the utility model awl sealing drain charge valve: it is made up of valve body, adjusting nut, nut, spring, positioning seat, spool and suction tude, steam outlet pipe, the effective silver soldering of inlet, outlet is connected on the valve body, the front port that it is characterized in that the valve body chamber tightens up and is designed to suction port, its inboard is provided with spool, spool is embedded on the positioning seat, and the positioning seat rear end is provided with a spring, and spring is controlled by adjusting nut, by valve rear end nut is set, seals.
Described valve body is a material with copper, makes a tubular structure, and front port tightens up and is set to suction port, and sidewall is provided with an air outlet, and the inside and outside sidewall of valve rear end mouth is provided with screw thread.
Described spool is a material with the teflon, makes a conical structure, and cone diameter is greater than suction port, and the circular cone inclined-plane is 45 °.
Adopt above-mentioned measure, awl of the present utility model sealing drain charge valve can the automatic on-off suction tude, regulates the air conditioner bypass pressure, compared with prior art have simple in structure, easy to manufacture, the saving cost.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated
Fig. 1, be the structural representation of awl of the present utility model sealing drain charge valve
The figure number explanation:
1, valve body 11, valve body chamber 12, internal thread 13, outside thread
14, suction port 15, air outlet 2, adjusting nut 3, nut

8, steam outlet pipe
With reference to the accompanying drawings as can be seen, awl of the present utility model sealing drain charge valve is by valve body 1, adjusting nut 2, nut 3, spring 4, positioning seat 5, spool 6 and suction tude 7, steam outlet pipe 8 is formed, suction tude 7 and steam outlet pipe 8 usefulness silver soldering are connected on the suction port 14 and air outlet 15 on the valve body 1, spool 6 is embedded on the positioning seat 5, positioning seat 5 rear ends are provided with spring 4, spring 4 is controlled by adjusting nut 2, adjusting nut 2 spirals are installed in the internal thread 12 of valve body 1, then nut 3 is installed on outside thread 13 at valve body 1 rear port spiral, like this, when the air condition compressor working load increases, then spool 6 is opened on air pressure rising top in the suction tude 7, spring 4 is compressed, making gas pass through steam outlet pipe 8 discharges, after air pressure descended, spool 6 rebounded with spring and seals suction port 14, and compressor recovers proper functioning, to keep system's internal pressure normal thereby play, and avoids the effect of compressor overload operation.
Described valve body 1 is a material with copper, makes a tubular structure, in a valve body chamber 11 is arranged, front port shrink to form a suction port 14, sidewall is provided with an air outlet 15, the rear end mouth inner and outer side respectively is provided with screw thread 12,13.
Described spool is a material with the teflon, makes taper shape, and the bottom surface diameter is greater than suction port 14, and the circular cone inclined-plane is 45 °.
