Description
(1), technical field
The utility model relates to the device on a kind of gas appliance, particularly a kind of device that prevents gas meter or the water inlet of combustion gas low-pressure pipe network.
(2), technical background
In daily life, because of the natural gas water heater is being installed, especially after the maintenance, usually tracheae and water pipe dislocation are joined, cause the water of water pipe to be gone in the gas meter, even water enters among the whole natural gas low-pressure pipe network, causes gas meter and low-pressure pipe network by water slug, makes a family, building, a building or a sub-district can't use major accident fully.After this accident occurring, common wipe-out mode is through complicated procedures of forming such as ditching, moving weldering, draining, combustion gas emptying purgings by the professional, just can make gas meter, low-pressure pipe network recover normal operating condition, this not only consuming time and consumption manpower, also to expend tens, hundreds of, even the economic loss of several thousand Renminbi is after the gas meter water inlet simultaneously, can cause bigger influence to the precision of metering, shorten the serviceable life of gas meter and pipe network equipment.
(3), summary of the invention
The purpose of this utility model just provides a kind of simple in structure, with low cost, easy for installation and service-strong gas meter water-stop, when misloading water, tracheae, it can prevent effectively that sealing enters in gas meter and the combustion gas low-pressure pipe network, avoids causing unnecessary economic loss.
The purpose of this utility model is to realize by such technical scheme, it is to be made of a differential retaining valve, this pressure reduction retaining valve includes valve body, Valve core blade and the valve gap of bringing circulation road into, going out circulation road, the valve gap that is threaded with valve body surrounds a valve pocket with valve body, other influent stream passage of branch is arranged in the valve pocket, go out the valve port that circulation road communicates, be placed with the Valve core blade that matches with valve port in the valve pocket versatilely, Valve core blade or valve body are provided with and go out the mechanism of qi structure excessively that circulation road communicates.The utility model is installed on the efferent duct of gas meter, that is: the delivery outlet of gas meter is communicated with the influent stream passage, go out circulation road and communicate, perhaps the utility model is installed in the efferent duct place of combustion gas low-pressure pipe network with tracheae.The utility model can level be installed, and also can vertically install.The utility model is to use like this: when normally using, natural gas enters in the valve pocket through the influent stream passage, promoting Valve core blade moves to the valve port that goes out on the circulation road, owing to cross the effect of mechanism of qi structure, make valve pocket all the time with go out circulation road and communicate, therefore, natural gas enters in the tracheae after flowing to out circulation road through the mechanism of qi structure.When installing or maintenance gas heater process, during because of carelessness with water pipe and tracheae arranged in dislocation, water in the water pipe enters valve pocket through the influent stream passage, because hydraulic pressure is more much bigger than the pressure of natural gas, therefore, the water of coming in promotes Valve core blade and moves to the valve port of influent stream passage, until this valve port is blocked, thereby anti-sealing enters in gas meter or the combustion gas low-pressure pipe network, avoids causing unnecessary economic loss.
Owing to adopted technique scheme, the utlity model has simple in structure, with low cost, easy for installation and use advantages such as reliable, when misloading water, tracheae, it can prevent effectively that sealing enters in gas meter and the combustion gas low-pressure pipe network, avoids causing unnecessary economic loss.

(5), embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Shown in Fig. 1,2,3 or 4, the utility model is to be made of a differential retaining valve, this pressure reduction retaining valve includes and brings circulation road 1 into, goes out valve body 3, Valve core blade 4 and the valve gap 5 of circulation road 2, the valve gap 5 that is threaded with valve body 3 surrounds a valve pocket with valve body 3, other influent stream passage 1 of branch is arranged in the valve pocket, go out the valve port that circulation road 2 communicates, be placed with the Valve core blade 4 that matches with valve port in the valve pocket versatilely, Valve core blade 4, valve body 3 or valve gap 5 are provided with and go out the mechanism of qi structure excessively that circulation road 2 communicates.The utility model is installed on the efferent duct of gas meter, that is: the delivery outlet of gas meter is communicated with influent stream passage 1, go out circulation road 2 and communicate, perhaps the utility model is installed in the efferent duct place of combustion gas low-pressure pipe network with tracheae.The utility model is to use like this: when normally using, natural gas enters in the valve pocket through influent stream passage 1, promoting Valve core blade 4 moves to the valve port that goes out on the circulation road 2, owing to cross the effect of mechanism of qi structure, make valve pocket all the time with go out circulation road 2 and communicate, therefore, natural gas enters in the tracheae after flowing to out circulation road 2 through the mechanism of qi structure.When installing or maintenance gas heater process, during because of carelessness with water pipe and tracheae arranged in dislocation, water in the water pipe enters valve pocket through going out circulation road 2, because hydraulic pressure is more much bigger than the pressure of natural gas, therefore, the water of coming in promotes Valve core blade and moves to the valve port of influent stream passage 1, until this valve port is blocked, thereby anti-sealing enters in gas meter or the combustion gas low-pressure pipe network, avoids causing unnecessary economic loss.
As shown in Figure 1, crossing the mechanism of qi structure can be that gas passage 6 was set on Valve core blade 4, and this is crossed gas passage 6 one ends and communicates with going out circulation road 2, and the other end communicates with valve pocket.When Valve core blade 4 covered out the valve port of circulation road 2, natural gas can enter out in the circulation road 2 by crossing gas passage 6.
As shown in Figure 2, crossing the mechanism of qi structure can be that Valve core blade 4 is provided with and goes out the mistake air drain 7 that circulation road 2 is that match and communicate with valve pocket.When Valve core blade 4 covered out the valve port of circulation road 2, natural gas can enter out in the circulation road 2 by crossing air drain 7.
As shown in Figure 3, crossing the mechanism of qi structure also can be to be provided with gas limiting stand 8 in the corresponding Valve core blade of the valve port that goes out circulation road 24 sides.When Valve core blade 4 is shifted to out the valve port of circulation road 2, owing to cross the position-limiting action of gas limiting stand, valve pocket is communicated all the time with going out circulation road 2, natural gas can enter out in the circulation road 2.
As shown in Figure 4, crossing the mechanism of qi structure can also be that valve body 3 or valve gap 5 were provided with gas passage 9, crosses gas passage 9 one ends and communicates with going out circulation road 2, and the other end communicates with valve pocket.When Valve core blade 4 covered out the valve port of circulation road 2, natural gas can enter out in the circulation road 2 by crossing gas passage 9.
Shown in Fig. 1,2,3 or 4, in order to strengthen sealing, anti-sealing enters in gas meter or the combustion gas low-pressure pipe network, is provided with gasket seal 10 with the corresponding Valve core blade of the valve port of influent stream passage 14 sides.
Shown in Fig. 3,4, in order to prevent Valve core blade 4 deflections, Valve core blade 4 is provided with the anti-side spin 11 of guiding.
