Abstract
The utility model provides an automatic unloading valve of a compressor pipeline and relates to the technical field of pressure release valves. The problem that when a compressor unloads automatically, pressure gas in the pipeline can not be exhausted automatically is solved. The automatic unloading valve of the compressor pipeline comprises a valve body and is characterized in that the valve body is provided with three connectors. The three connectors respectively comprise a pipeline gas connector, a high-pressure gas connector and an unloading connector. A piston and a valve core are arranged in the valve body and the valve core is connected with the piston. Reset springs are sleeved on the valve core. The automatic unloading valve of the compressor pipeline is simple and reasonable in structure design. After being connected with an electrical control system and a high-pressure gas source, the automatic unloading valve of the compressor pipeline can automatically exhaust the pressure gas in the compressor pipeline, and the automation control can be achieved.
Description
Technical field:
The utility model relates to the Decompression valves technical field, is specifically related to a kind of Compressor Pipes automatic relieving valve.
Background technique:
At present, compressor is when automatic deloading, and the pressed gas in the pipeline can not be discharged automatically, has increased the power consumpiton of compressor operating, shuts down when starting and can cause motor overload.
The model utility content:
The purpose of this utility model is to provide a kind of Compressor Pipes automatic relieving valve, to solve compressor when the automatic deloading, the problem that the pressed gas in the pipeline can not be discharged automatically.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of Compressor Pipes automatic relieving valve, comprise valve body, it is characterized in that: described valve body is provided with three interfaces, respectively pipeline gas interface, high pressure air interface and vent, be provided with piston and the spool that is connected piston in the described valve body, described valve core upper sleeve has Returnning spring.
Described pipeline gas interface and high pressure air interface are oppositely arranged.
Described vent is vertical with valve body.
After the Compressor Pipes automatic relieving valve is installed on the pipeline, also be connected with high-pressure air source with electric control system (pressure controller, two-position three way magnetic valve).
When system pressure reaches when needing the off-load value, pressure controller sends electrical signal (passive switch amount) and opens to normally closed solenoid valve, make pressurized gas flow to the high pressure air interface of Compressor Pipes automatic relieving valve through solenoid valve, the pressurized gas pushing piston drives the valve core movement Open valve, makes pipeline gas emit off-load from the vent of this valve.When system pressure reduced the normal operation of recovery, pressure controller was given again solenoid valve one electrical signal (passive switch amount), made it recover normally off.At this moment the pressurized gas in the valve body are discharged through the drain of solenoid valve, and this moment, spool and piston set back under the effect of Returnning spring and pipeline gas, and the vent of this valve is closed, and finishes the off-load work of pipeline.
The utility model structural design advantages of simple, with electric control system with after high-pressure air source is connected, the pressed gas in the Compressor Pipes can be discharged automatically, can realize automation control.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is automatic deloading process schematic diagram.
1. pipeline gas interfaces wherein; 2. Returnning spring; 3. high pressure air interface; 4. spool; 5. valve body; 6. vent.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with specifically illustrating and specific embodiment, further set forth the utility model, but be not to limit protection domain of the present utility model.
Please refer to Fig. 1, a kind of Compressor Pipes automatic relieving valve comprises valve body 5, valve body 5 is provided with three interfaces, pipeline gas interface 1, high pressure air interface 3 and vent 6 are provided with piston 7 and the spool 4 that is connected piston 7 in the valve body 5 respectively, and cover has Returnning spring 2 on the spool 4.
As shown in Figure 1 and Figure 2, after the Compressor Pipes automatic relieving valve is installed on the pipeline, also be connected with high-pressure air source with electric control system (pressure controller, two-position three way magnetic valve).
When system pressure reaches when needing the off-load value, pressure controller sends electrical signal (passive switch amount) and opens to normally closed solenoid valve, make pressurized gas flow to the high pressure air interface of Compressor Pipes automatic relieving valve through solenoid valve, the pressurized gas pushing piston drives the valve core movement Open valve, makes pipeline gas emit off-load from the vent of this valve.When system pressure reduced the normal operation of recovery, pressure controller was given again solenoid valve one electrical signal (passive switch amount), made it recover normally off.At this moment the pressurized gas in the valve body are discharged through the drain of solenoid valve, and this moment, spool and piston set back under the effect of Returnning spring and pipeline gas, and the vent of this valve is closed, and finishes the off-load work of pipeline.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.It only is embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
