Description
Technical field
The utility model relates to the valve connections in gas pipeline, the gas meter switch valve of a kind of improvement specifically.
Background technique
Combustion gas is that daily life brings conveniently in daily life, in order to better person easy to use controls circulation and the closedown of combustion gas, needs to arrange switch valve between gas pipeline and gas meter, with control switch and calculated flow rate.Current this switch valve comprises switch valve main body, arranged on left and right sides is provided with suction tude, steam outlet pipe can connect gas pipeline and gas meter, connect gas meter side to be connected nut and Anti-dismantle cap, the design safety of this switch valve is antitheft, but there is certain defect installing, the connection of gas pipeline and gas meter needs through switching valve body, but gas pipeline and switching valve body need to coordinate curve accessory to be connected, make the installation of switching valve body too loaded down with trivial details like this, and the more many situations about more easily leaking air of tie point.
Summary of the invention
The deficiency of and sealing difference loaded down with trivial details for the installation existed in prior art, the utility model provides a kind ofly installs gas meter switch valve that is simple, good seal performance.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of gas meter switch valve, comprise the switch valve main body with air valve switch, it is suction tude on the downside of switch valve main body, this suction tude is connected with gas pipeline, the integrated L-type steam outlet pipe with switch valve main body is provided with on the upside of switch valve main body, this L-type steam outlet pipe is connected with gas meter, L-type steam outlet pipe outlet end is provided with draw-in groove, this draw-in groove is embedded with the snap ring protruding L-type steam outlet pipe outer surface, L-type steam outlet pipe overcoat has attaching nut, this attaching nut is provided with internal thread, and attaching nut's left end is provided with inner edge boss, and this inner edge boss internal diameter is less than snap ring external diameter.
Adopt the model utility of technique scheme, gas pipeline is connected with on admission line, L-type steam outlet pipe overcoat attaching nut during installation, snap ring is stuck on the draw-in groove of L-type steam outlet pipe port, make the attaching nut with inner edge boss cannot depart from L-type steam outlet pipe, attaching nut is threaded with gas meter, makes combustion gas flow through switch valve main body by gas pipeline and enters gas meter.Switch valve body shape can make gas pipeline and gas meter directly be connected under normal service condition for " L " type, without the need to the accessory of other indexings, switch valve main body and the one-body molded Air Leakage Defect avoiding multiple fitment combination and exist of L-type steam outlet pipe, this structural design makes the installation between gas pipeline and gas meter more efficient and convenient simultaneously.
Further restriction, the incorgruous extension in lateral part of air valve switch and L-type steam outlet pipe, this structure and direction, air valve switch place different from the lateral part bearing of trend of L-type steam outlet pipe, can ensure that air valve switch is unobstructed when rotated.
Further restriction, the port of L-type steam outlet pipe is provided with installation base, and installation base is provided with stuffing box gland.Seal rubber sleeve is set, the object of installation base is when being to be connected with switch valve by gas meter, ensure gas meter and seal when being connected between switch valve.
Further restriction, in order to avoid lawless person's reversal connection gas meter or substitute gas meter for another surreptitiously, also be provided with the outer Anti-dismantle cap be enclosed within outside attaching nut of coupling, and the outer circumference of attaching nut's right-hand member is provided with attaching nut's exterior bayonet slot, Anti-dismantle cap right-hand member inner circumferential is provided with an Anti-dismantle cap inner card cage mated with attaching nut's exterior bayonet slot, be arranged with steel wire card in Anti-dismantle cap inner card cage, when being enclosed within attaching nut outside Anti-dismantle cap coupling, steel wire card is stuck in again in attaching nut's exterior bayonet slot simultaneously.Such structure, after gas meter and switch valve are connected, to be enclosed within attaching nut outside Anti-dismantle cap again, be equivalent at mounted joint overcoat an Anti-dismantle cap, this tamper cover only can rotate in a circumferential direction, can not moving axially, just when not damaging tamper cover, gas meter can not be dismantled after installing.Adopt the novel switched valve of gas meter of such structure, there is anti-theft feature, lawless person's reversal connection gas meter can be avoided or substitute gas meter for another surreptitiously, meet national relevant regulations.
Further restriction, Anti-dismantle cap and attaching nut not with the use of time, on attaching nut's inner card cage, cover has collar.Because Anti-dismantle cap belongs to single use structure with coordinating of attaching nut, on attaching nut's inner card cage, cover has collar namely to avoid Anti-dismantle cap before use to cause using with coordinating of attaching nut.
Further restriction, described collar is made up of elastic material.Consider that collar easy for installation has elasticity and can be fixed on attaching nut's inner card cage, simultaneously easy to use, reduce costs.
The utility model phase usefulness, L-type steam outlet pipe and switch valve main body one-body molded, buying that the combination decreasing multiple accessory causes trouble and install the problem causing gas leakage; Attaching nut's exterior bayonet slot puts collar, solves because misoperation causes attaching nut to coordinate with Anti-dismantle cap, cause waste finished product to reduce utilization rate.Therefore the utility model install and use with Material selec-tion in have easy for installation, reduce costs, practical beneficial effect.
