Description
Technical field
The utility model relates to air compressor gas valve technical field, especially relates to a kind of air compressor gas valve with two emptying runners.
Background technique
Suction valve is that the tolerance of piston type air compressor regulates core component, and particularly crucial in the auxiliary equipment of piston type air compressor, its quality directly affects the overall performance of helical-lobe compressor.Patent announcement CN201858159U discloses a kind of screw-rod air compressor gas valve, existing suction valve is referring to accompanying drawing 1 and accompanying drawing 2, it mainly comprises valve body 1, cylinder 2, atmospheric valve 3 and solenoid valve 4, atmospheric valve 3 is located on valve body 1, solenoid valve 4 is connected with atmospheric valve 3, in valve body 1, be provided with turnover panel 5 and butterfly valve 6, turnover panel 5 is provided with inlet hole 7, cylinder 2 opens and closes for controlling turnover panel 5, the sidewall of valve body 1 is provided with emptying runner 8, and this emptying runner 8 is communicated with the cavity of the drain of atmospheric valve 3 and the interior turnover panel of valve body 15 tops.
During suction valve loaded state, air enters in head by the inlet hole 7 on turnover panel 5, make barrel of oil and gas internal pressure reach fast system and start setting value, two-bit triplet normal-closed electromagnetic valve 4 obtains electric, under gas pressure effect, cylinder 2 piston rods are up, and turnover panel 5 is opened, large quantity of air enters in suction valve by valve port, and now atmospheric valve 3 is in closed condition.
During suction valve unloaded state, when barrel of oil and gas internal pressure reaches CLV ceiling limit value, pressure transducer sends signal, 4 power-off of two-bit triplet normal-closed electromagnetic valve, cylinder 2 loses External Force Acting, at acting force of the spring lower piston return turnover panel 5 alone, close, now air can only enter head by inlet hole 7, supplements head required throughput when unloading, solenoid valve 4 power-off simultaneously, atmospheric valve 3 spools are opened under interior pressure effect, by drain emptying, barrel of oil and gas air pressure inside are lowered.
When suction valve is shut down emptying state, barrel of oil and gas air pressure inside drops to while shutting down setting value, motor stopping, and under the effect of head internal pressure, butterfly valve 6 cuts out anti-spraying oil, and atmospheric valve 3 continues emptying.
When suction valve unloaded state, because air can only enter head by inlet hole 7, the aperture of inlet hole 7 is less, and the pressure difference at turnover panel two ends Shang Xia 5 is larger, thereby when air during by inlet hole 7 flow velocity comparatively fast can produce and utter long and high-pitched sounds, cause suction valve noise when unloaded state larger.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of air compressor gas valve with two emptying runners, it sets up the second emptying runner on the sidewall of valve body, this the second emptying runner is communicated with the drain of atmospheric valve with turnover panel below cavity in valve body, thereby reduce air by the flow velocity of turnover panel inlet hole, to reduce suction valve noise when the unloaded state.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of air compressor gas valve with two emptying runners, comprise valve body, cylinder, atmospheric valve and solenoid valve, atmospheric valve is located on valve body, solenoid valve is connected with atmospheric valve, in valve body, be provided with turnover panel and butterfly valve, butterfly valve top is the suction port of valve body, turnover panel is located at this suction port place rotationally, turnover panel in cylinder and valve body is in transmission connection, turnover panel is provided with inlet hole, the sidewall of valve body is provided with the first emptying runner and the second emptying runner, the first emptying runner is communicated with the cavity of the turnover panel top in the drain of atmospheric valve and valve body, the second emptying runner is communicated with the cavity of the turnover panel below in the drain of atmospheric valve and valve body.
Wherein, the sidewall of described valve body outside is provided with the groove that the drain with described atmospheric valve matches, and the outer end of described the first emptying runner and described the second emptying runner is all located in this groove.Described valve body is provided with the emptying being connected with the first emptying runner and regulates mouth.
Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:
The air compressor gas valve with two emptying runners described in the utility model, the sidewall of valve body is provided with the first emptying runner and the second emptying runner, this the second emptying runner is communicated with the drain of atmospheric valve with turnover panel below cavity in valve body, when suction valve unloaded state, a gas part of releasing from the drain of bleeder valve is discharged from the first emptying runner, some enters the cavity of turnover panel below from the second emptying runner, to supplement the throughput entering from turnover panel inlet hole, thereby reduce air by the flow velocity of turnover panel inlet hole, to reduce suction valve noise when the unloaded state.
