Abstract

The invention relates to an air pressure relief switch which is characterized by comprising an outer main body and a rotating seat, wherein the rotating seat is correspondingly articulated with the outer main body, is provided with a ball part and can be rotated; the outer main body and one end of the rotating seat are respectively provided with a joint part connected with a pneumatic component or an air supply power source; an outer main body channel and a gap of a wall are arranged in the outer main body; and a rotating seat channel communicated with the outer main body channel is arranged on the rotating seat. Thus, the air supply power source transmits air through the outer main body channel and the rotating seat channel to the pneumatic component, the rotating seat channel can be closed by rotating the rotating seat to block the air supply, and the air in the pneumatic component can be discharged through the gap of the outer main body channel, thereby achieving the pressure relief design of the pneumatic component.

Description

Air pressure relief switch

Technical field

The present invention relates to a kind of air pressure relief switch, especially relate to a kind of switch structure that lets Pneumatic assembly lose heart.

Background technique

General tradition is used to adjust the air regulating device between pneumatic cylinder and air feed power source; Be as shown in Figure 6; Be a kind of gas adjustment valve arrangement, these adjustment valve 5 inside are provided with a channel 51, and these channel 51 1 ends link pneumatic cylinder pipeline 52; The other end links air feed power source [like pumping] pipeline 53; Again by passage 51 central authorities lock one can cover passage regulating lever 54, the degree of depth of utilizing regulating lever 54 to lock, correspondence are covered passage 51 caliber size and are regulated the gas flow person in the air feed power source input air pressure cylinder.

Yet, above-mentioned gas adjustment valve arrangement, the stroke that stretches in the action to pneumatic cylinder is basically done the adjustment of air inflow size; But when needing release in the pneumatic cylinder internal pressure is excessive, its 5 on valve of adjustment can't reach this effect, therefore; Generally know this art and all take pneumatic cylinder pipeline 52 is disassembled, to let the inner air pressure relief of pneumatic cylinder come out, so; Could under the inner pressure-less state of pneumatic cylinder, adjust, wait adjustment suitably after, again pipeline is connected back.And this pressure release acts may very bothers, and need are assembled after pipeline is dismantled pressure release again, so process is comparatively numerous and diverse.

Summary of the invention

Technical problem to be solved by this invention be to above-mentioned existing technology provide a kind of simple in structure, can do air pressure inside and let out the effect of removing and connecting adjustment; Needn't be when needing adjustment at every turn; Pipeline is pulled out pressure release, refill the air pressure relief switch of cumbersome procedure such as upper pipeline after the adjustment.

The present invention solves the problems of the technologies described above the technological scheme that is adopted: this air pressure relief switch; Mainly has bulb and can be by the rotary seat of turn direction by the corresponding pivot joint one of an outer main body; Outer main body and rotary seat one end are respectively equipped with outer main body connector portions and the rotary seat connector portions that links with Pneumatic assembly or air feed power source; Be provided with the breach of outer body passageways and wall in the outer main body, and rotary seat is provided with the rotary seat passage that communicates with outer body passageways; By this; Thereby let the air feed power source supply with Pneumatic assembly through outer body passageways and the gas transmission of rotary seat passage; And can seal the rotary seat passage via the turn rotary seat and stop air feed, and let the interior gas of Pneumatic assembly discharge through breach with outer body passageways, to reach the pressure release purpose of Pneumatic assembly.

As improvement, the indentation, there of the rotary seat of air pressure relief switch provided by the invention main body outside the correspondence of pivot-connecting position is provided with a protruding block, fastens in indentation, there to utilize protruding block, and does the corresponding spacing of outer main body and rotary seat passage.

Further; The outer main body connector portions of air pressure relief switch provided by the invention further includes first pressing member, first jointing base, first shell fragment, first bowl of seat and first gas-tight ring; First gas-tight ring is by the corresponding clip air feed of first shell fragment power source pipeline; But reach mat first pressing member and support the design of pulling first shell fragment and unclasping air feed power source pipeline, make the assembling of air feed power source pipeline more easy.

The rotary seat connector portions of air pressure relief switch provided by the invention includes second pressing member, second jointing base, second shell fragment, second bowl of seat and second gas-tight ring; Second gas-tight ring is by the moving assembly pipeline of the corresponding clip air feed of second shell fragment; But reach mat second pressing member and support the design of pulling second shell fragment and unclasping the Pneumatic assembly pipeline, make the assembling of Pneumatic assembly pipeline more easy.

The outer main body connector portions of air pressure relief switch provided by the invention and rotary seat connector portions can adopt rapid pipe joint design, connect Pneumatic assembly and air feed power source to utilize the rapid pipe joint correspondence, let the more fast and convenient person of assembling of pipeline.

Compared with prior art, the invention has the advantages that:

1, air pressure relief switch of the present invention, but by the rotary seat of the ball valve design of turn, come correspondence to open the channel with closed outer main body and rotary seat, let the pipeline of Pneumatic assembly lose heart simultaneously via the breach of outer main body, reach the effect that pressure release is adjusted; And in desire when adjustment at every turn, pulled out pressure release with pipeline, refills cumbersome procedure such as upper pipeline after the adjustment.

2, air pressure relief switch of the present invention utilizes pressing member, jointing base, shell fragment, bowl seat and a gas-tight ring to constitute connector portions, mainly by the corresponding clip pipeline of shell fragment, supports the design of pulling shell fragment and unclasping pipeline but reach the mat pressing member, makes the assembling of pipeline more easy.

3, air pressure relief switch of the present invention can utilize the rapid pipe joint correspondence to connect Pneumatic assembly and air feed power source by the design of rapid pipe joint, makes the assembling of pipeline more fast and convenient.
