Description

Safety angle valve for domestic gas cylinder

The technical field is as follows:

the utility model relates to a bottled gas angle valve especially relates to a domestic gas bottle safety angle valve that can ensure safety.

Background art:

at present, the gas cylinder safety angle valve which is used by people is the original 'gas cylinder safety angle valve' of the invention, and the main defects of the valve are four: firstly, the structure that the switch hand wheel is linked to open and close the gas valve rod is complex, so that poisoning or explosion accidents caused by abrasion, looseness and gas leakage are easy to occur; secondly, before and after gas filling of the gas station and people use the gas station each time, the gas station needs to be manually opened and closed, and the gas station is very inconvenient to use; thirdly, the self-closing function at the air inlet and the air outlet is unstable, and the potential safety hazard exists seriously (namely, in the transportation oscillation process, the valve seat is easy to loosen and fall off to cause a large amount of air leakage accidents); fourthly, at the air inlet and the air outlet, a reliable gas stealing prevention device (namely, a one-time gas stealing prevention locking wire) is not arranged, so that a user suffering from gas stealing is easily connected with the secondary bad gas service station (namely, the secondary bad gas service station is often connected with a plurality of bottles of full gas and is added into an empty bottle, and six bottles of gas are sold to the user).

The invention content is as follows:

in order to solve the above problems, the utility model provides a domestic gas bottle safety angle valve, it is improved on the basis of the "gas steel bottle safety angle valve" of the original invention utility model patent (original patent number: ZL200520106929.9), it includes the casing, the casing has the business turn over gas passage, the first consequent closing valve seat, the second consequent closing valve seat, business turn over gas port that communicate each other, characterized by: a second forward closing valve seat outer sleeve with an O-shaped anti-leakage air-tight sealing rubber ring at the periphery is arranged in the air inlet and outlet, and is tightly screwed, clamped and matched through a positioning small inserted pin or a small screw, so that the danger problem that the gas bottle is loosened, separated and leaked in the transportation oscillation process is effectively solved; a forward closing gas elastic valve core B and a second forward closing valve seat are inserted into the left side of a second forward closing valve seat in the center of the forward closing valve seat sleeve

Has the advantages that:

the utility model provides a pair of domestic gas bottle safety angle valve beneficial effect has four: the first is that: the structure is simple, and the danger problem of poisoning or explosion caused by abrasion, looseness and air leakage of a hand wheel switch does not exist; secondly, the following steps: people do not need to manually open and close before and after each use, and the use is very convenient; thirdly, the method comprises the following steps: the self-closing function at the air outlet is stable, and potential safety hazards do not exist (namely, the problem of a large amount of air leakage accidents caused by loosening and falling off in the transportation oscillation process is avoided); fourthly, the method comprises the following steps: a reliable gas stealing prevention device (namely, a one-time anti-stealing locking wire) is arranged at the gas inlet, and the opportunity that a second-level bad gas service station takes over a gas stealing pit to damage a user is avoided.

The specific implementation mode is as follows:

(as shown in figure 1), the utility model provides a domestic gas bottle safety angle valve, it is improved on the basis of the utility model patent "gas cylinder safety angle valve" of former invention, (former patent number: zl200520106929.9), it includes casing (1), casing (1) has the business turn over gas passage (2) of intercommunication, first cisoid closes valve seat (3) second cisoid and closes valve seat (4), business turn over gas port (5), its characteristic is: a second forward closing valve seat outer sleeve (7) with an O-shaped sealing rubber ring (6) at the periphery is arranged in the air inlet and outlet (5) and is screwed and clamped by a positioning small plug pin or a small screw (8); a forward closing coal gas elastic valve core B (9) is inserted into the left side of a second forward closing valve seat (4) in the center of a forward closing valve seat outer sleeve (7) to be matched with the second forward closing valve seat (4), and a hollow ejector rod (10) at the right end of the elastic valve core B (9) extends out of the second forward closing valve seat (4); inserting a concave-convex mandril (11) at the left side of the elastic valve core B (9) into a mandril guide hole (12), and aligning and propping a smooth round head (15) at the upper end of a forward closing gas elastic valve core A (14) in a first forward closing valve seat (3) to match with an arc-shaped groove (13) in the concave-convex mandril (11); in order to prevent a user from being damaged by gas stealing and pits of a poor merchant of a secondary gas station, a small through hole (16) is drilled at proper positions on two sides of the gas inlet and outlet (5), and a plastic wire (17) which is locked by one-way tightening is inserted to match with the small through hole.

Description of the method of use and working principle:

(as shown in fig. 1), when producing a new gas cylinder, the safety angle valve for a household gas cylinder provided by the utility model is fixedly screwed on the new gas cylinder (note that the gas cylinder is not seen in the attached drawing, which can be understood), and then is supplied to a gas station for gas filling; after the gas cylinder is filled with gas, the gas filling station related personnel are responsible for adding a plastic locking wire (17) into a small through hole (16) on the gas inlet and outlet (5) for tightening and blocking so as to prevent the gas stealing of a connecting pipe of a secondary bad gas filling station.

(as shown in fig. 1), when a user needs to use the angle valve, the user firstly cuts off the plastic wire (17) on the angle valve; (as shown in fig. 2), then, a hand wheel (17) on the safety pressure reducing valve (16) is screwed down forcibly into the air inlet and outlet (5), so that a sealing top head (18) of the pressure reducing valve is connected with an elastic valve core B (9) to jack the elastic valve core A (14) inwards; when the household safety pressure reducing valve is started or stopped, a user can rotate the household safety pressure reducing valve from a manual gas on-off switch (19) on the household safety pressure reducing valve (16).
