The purpose of this utility model provide a kind of installation,, maintenance, piped gas attachment valve easy to use, safe.
In order to achieve the above object, the technical solution adopted in the utility model is: piped gas attachment valve described in the utility model comprises joint and fittings body, be equipped with between fittings body and the joint and be automatically locked and trip gear, it is characterized in that: joint one end is the gas pipe line connecting end, one end is the fittings body connecting end, and a gas passage penetrator is arranged in the joint, and a vent plug is arranged in the gas passage, vent plug one end is pressed with spring, and an end compresses the outlet of gas passage and the outlet of sealing gas passage; Fittings body one end is the coal gas implement connecting end, an other end is the joint connecting end, the joint connecting end of fittings body convexes to form one and can stretch in the gas passage of joint and back down the vent plug jacking block of vent plug, the gas passage of one both ends open is also arranged in the fittings body, and wherein an opening end is positioned on the vent plug jacking block.
Its joint of gas pipe line attachment valve described in the utility model is fixed on the gas pipe line, fittings body inserts joint, vent plug jacking block on the fittings body backs down vent plug, this moment, the gas passage of fittings body communicated with the coal gas joint of joint, meanwhile, between fittings body and the joint be automatically locked and trip gear is automatically locked, joint and fittings body fuse, thereby realize ventilation; Be automatically locked and trip gear when stirring, joint and fittings body are promptly broken away from, vent plug loses compressing of jacking block, compresses the outlet of gas passage under the compressing of spring again, the outlet of sealing gas passage, whole erection, convenient, the safety of using process.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 piped gas attachment valve described in the utility model.
Embodiment:
As shown in Figure 1, joint 1 comprises connection block 24, seal ring 2, column valve 3, spanner 4, connects valve body 5, connects valve head 6, vent plug 16, spring 17, seal washer 18, seal washer 15.The gas passage 19 that consistent cross-under head is arranged in the joint 1, connection block 24 left ends are the port that is connected with gas pipe line, column valve is installed on the connection block 24, leading to, closing with control gas passage 19.Connect valve body 5 be installed on connection block 24 right-hand member, an end that connects valve body 5 is fixed on the connection block 24, there is a periphery to have the vent plug 16 of vent 25 in the gas passage 19 within it, the inwall of vent plug 16 and gas passage 19 movingly, vent plug 16 left ends are pressed with spring 17, right-hand member compresses the seal ring 15 of the outlet end of gas passage 19, the outlet end of sealing gas passage 19.Be with one at the right-hand member that connects valve body 5 and connect valve head 6, connecting valve head 6 is a body, at connection valve head 6 outer walls one v-depression 20 is arranged.When using at ordinary times, column valve 3 is opened, gas passage is connected; When needs are changed the component that connect valve body 5 and connection valve head 6, close column valve, can pull down to connect valve body 5 and connect valve head 6 and change, and not need whole joint is changed.
The gas passage 22 of always wearing fittings body 12 is also arranged in the fittings body 12.The right-hand member of fittings body 12. is and the connecting end of coal gas implement, and its left end then convexes to form a vent plug jacking block 21, and the side of vent plug jacking block 21 has through hole makes gas passage communicate with the external world.The front end of vent plug jacking block 21 can insert in the gas passage 19 of joint 1 and back down vent plug 16, and vent plug jacking block 21 middle parts are with seal ring 23, and it can form hermetic seal with the inwall that connects valve head.The left end of fittings body 12 have one with connect the mechanism that valve head 6 is automatically locked and throws off.
It is automatically locked and trip gear is a prior art, as long as can be realized being automatically locked mutually of joint 1 and fittings body 12 and throw off.Described being automatically locked of present embodiment comprises the V-shaped groove 20 of the right outer end that connects valve head 6 that is positioned at joint 1 with trip gear, and ball 14, joint sleeve 11, outer casing spring 9, thrust slide block 13 and the interior sleeve spring 10 of fittings body left end.Joint sleeve 11 is a body, is placed in the left end of fittings body 12, has through hole on the joint sleeve 11, ball 14 is embedded in the through hole, and the ball outside is with and connects overcoat 8, connects overcoat 8 right-hand members and is pressed with outer casing spring 9, ball 14 inboards are with a thrust slide block 13, and thrust slide block 13 right-hand members are pressed with interior sleeve spring 10.At joint sleeve 11 left ends one thrust spring 7 is arranged in addition.
In the present embodiment, the link position between the component on all gas channel all adopts the seal ring sealing.
Connect valve head 6 and enforce joint sleeve 11 when joint 1 moves when joint sleeve 11 entangles, connect valve head 6 and oppress thrust slide block 13 to the right, sleeve spring 10 in 13 compressions of thrust slide block, when V-shaped groove 20 moved to the position of ball 14, ball 14 was fallen in the V-shaped groove 20, and outer casing spring 9 ejects, connect overcoat 8 bullets to thrust spring 7 places, stop further ejection, and connect the ejection of overcoat 8 inwalls sealing ball 14, realized being automatically locked of joint 1 and fittings body 12.Simultaneously, vent plug jacking block 21 Shens are gone into to connect in the valve body 5, and jack-up vent plug 16, and the side at vent plug jacking block 21 middle parts forms hermetic seal by seal ring 23 and the inwall that connects valve head, and this moment, the gas passage 19 of joint 1 was connected with the gas passage 22 of fittings body 12.Finish using, firmly stir and connect overcoat 8 compression garment springs 9, ball 14 loses and connects compressing of overcoat 8 and ejection from V-shaped groove 20, and thrust slide block 13 to left movement, arrives go back to the home position under the effect of interior sleeve spring 10, joint 1 ejects, vent plug 16 loses compressing of vent plug jacking block 21 simultaneously, moves right under the promotion of spring 17, gets back to the original place, again form hermetic seal, make tab closure.
