Abstract
A pipeline gas safety self-locking valve is improved on the basis of the prior gas valve and is characterized in that: a forward automatic closing gas valve device is additionally arranged at one end of a gas outlet of the existing gas valve to be matched, so that the purposes of self-locking gas and ensuring safety are achieved; an iron wire valve locking device is arranged at a proper position at the tail end of the gas outlet of the forward automatic gas valve closing device to be matched, so that the aim of locking the valve to prevent dangerous accidents caused by the gas stealing of a user is fulfilled; the valve has simple structure and low production cost, can facilitate the management work of pipeline gas companies, can install gas for entry at one time no matter whether a new building is built or an old building is transformed, saves the investment cost, cannot steal the gas before the user does not pay money to handle the procedure of opening an account, and ensures the safety.
Description
Technical field:
The present invention relates to a kind of pipeline gas switch valve, relate in particular to a kind of safety self-locking valve for pipe gas with auto-lock function.
Technical background:
Present commercially available pipeline gas switch valve, it is the regular tap valve, it does not have auto-lock function, when the combustion gas house lead in need be installed in advance by pipeline gas company, must take away switch knob and shut the air outlet, not only workload is big, can't avoid the individual user to steal gas voluntarily and use, and constitutes the generation of peril.
Summary of the invention:
Safety self-locking valve for pipe gas of the present invention, it not only can be replaced existing pipeline gas switch valve and use, and steals the function that gas uses but also have auto-lock function voluntarily with preventing the user, can guarantee the maximum safety that combustion gas is used.
Technological scheme:
Safety self-locking valve for pipe gas of the present invention, it is to improve to form on the basis of existing gas valve, comprise existing gas valve, valve has gas-entered passageway and the outlet passageway that is interconnected, outlet passageway one end of valve increase by one of installing forward the control valve unit of automatic self-closing gas match, described forward automatic self-closing gas control valve unit comprises spool, valve seat, the spool via, the anti-gas-leak O-ring seal, pressure spring, spring bearing housing, wherein the anti-gas-leak O-ring seal is inserted in the spool and with valve seat and matches, spool one end stretches out spool via outer end, and the other end matches with pressure spring; Pressure spring one end is enclosed within the spring bearing housing, and the other end matches with spool, matches with valve seat by the spring pressure pressed spool, reaches automatic self-closing gas and guarantees purpose of safety.Do not hold the appropriate position in the air outlet of automatic self-closing gas control valve unit forward, installing two locking-valve small through hole matches with the locking-valve device, described locking-valve device comprises locking-valve iron wire, locking-valve lead, the locking-valve iron wire is passed two locking-valve small through hole and matches with the locking-valve lead is locked.Reach and prevent that the user from stealing the gas use voluntarily and guaranteeing purpose of safety.
Beneficial effect:
Safety self-locking valve for pipe gas of the present invention, simple in structure, cost of production is low, the safety coefficient height, its major advantage is: the user do not pay handle account opening procedure before, guarantee not have gas leakage and prevent that the user from stealing gas voluntarily and using, simultaneously, can also reduce the cost of investment of pipeline gas company, no matter be that new building construction or aging blocks housing reform are made, all can disposable installation combustion gas user, conveniently management.
Description of drawings:
Accompanying drawing is the structural representation of facing of safety self-locking valve for pipe gas of the present invention.
Among the figure, 1, existing burnt gas switch valve; 2, gas-entered passageway; 3, outlet passageway; 4, automatic self-closing gas control valve unit forward; 5, spool; 6, valve seat; 7, spool via; 8, anti-gas-leak O-ring seal; 9, pressure spring; 10, spring bearing housing; 11, air outlet; 12, locking-valve small through hole; 13, locking-valve device; 14, locking-valve iron wire; 15, locking-valve lead.
Specific embodiments:
Safety self-locking valve for pipe gas of the present invention, it is to improve to form on the basis of existing gas valve, comprise existing gas valve (1), valve (1) has the gas-entered passageway (2) that is interconnected and outlet passageway (3), outlet passageway (3) one ends of valve (1) increase by one of installing forward the control valve unit of automatic self-closing gas (4) match; Described forward automatic self-closing gas control valve unit (4) comprises spool (5), valve seat (6), spool via (7), anti-gas-leak O-ring seal (8), pressure spring (9), spring bearing housing (10), and wherein anti-gas-leak O-ring seal (8) is inserted in the spool (5) and with valve seat (6) and matches; Spool (5) one ends stretch out spool via (7) outer end, and the other end matches with pressure spring (9); Pressure spring (9) one ends are enclosed within the spring bearing housing (10), and the other end matches with spool (5), match with valve seat (6) by pressure spring (9) pressed spool (5), reach automatic self-closing gas and guarantee purpose of safety.Do not hold the appropriate position in the air outlet (11) of automatic self-closing gas control valve unit (4) forward, installing two locking-valve small through hole (12) matches with locking-valve device (13), described locking-valve device (13) comprises locking-valve iron wire (14), locking-valve lead (15), locking-valve iron wire (14) pass two locking-valve small through hole (12) and with locked the matching of locking-valve lead (15).Reach and prevent that the user from stealing the gas use voluntarily and guaranteeing purpose of safety.Described forward automatic self-closing gas control valve unit (4) and locking-valve device (6) also can be used with various pipe joints, also can be used with the running water switch valve, all reach purpose of safety.Using method:
When need using, cut off locking-valve iron wire (14), load the equipment needed thereby joint then, make connecting head back down spool (5), combustion gas can unimpeded (do not have the diagram of use, be appreciated that).The device therefor of dismantling when stopping using, locked once more valve gets final product.
