Description
Technical field
The utility model relates to gas pipeline guard technology field, specifically, relates to a kind of gas pipeline water-inlet-proof protective gear.
Background technique
Along with a large amount of development of combustion gas terminal use, gas water-heater also becomes requisite household gas apparatus in people's life.Because the installation after sale in water heater market is chaotic, installation personnel level is uneven, and even a lot of user installs voluntarily.Therefore installation process intermediate frequency take place frequently raw by fuel tube misconnection to water outlet of water heater mouth, thus cause tap water to enter gas pipeline, damage gas-fired equipment, even initiation large size is stopped the supple of gas or steam accident.How effectively preventing gas pipeline from intaking, is the problem of those skilled in the art's primary study.
Model utility content
For overcoming prior art Problems existing, the utility model provide a kind of structure simple, design gas pipeline water-inlet-proof protective gear ingenious, with low cost, easy to use.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Gas pipeline water-inlet-proof protective gear; comprise the protection cylindrical shell of two ends with the internal thread interface mated with gas pipeline; near the limit dais protruding from protection cylinder inboard wall that one end internal thread is arranged; be connected to the bracket at the other end internal thread place; and to be placed in protection cylindrical shell and water blockoff ball between limit dais and bracket, wherein, limit dais and bracket are equipped with air passing hole; the diameter of water blockoff ball is less than the internal diameter of protection cylindrical shell, and is greater than the air passing hole diameter on limit dais.
Promote water blockoff ball for the ease of pressure, described water blockoff ball is made up of lightweight material, and lightweight material is also convenient to float on waterborne simultaneously.
Further, described bracket comprises the support body in mating with protection cylinder internal diameter, and is arranged at the outside thread mated outside support body and with the internal thread of protection cylindrical shell, and wherein, air passing hole is arranged on support body.
Blocking the air passing hole on bracket at nominal conditions in order to avoid spheroid, staggers mutually in the air passing hole position on described bracket and the air passing hole position on limit dais.
In order to not affect ventilation, the quantity of the air passing hole on described bracket is at least two.
In order to effectively intercept water inlet, the air passing hole on described limit dais is coaxial with protection cylindrical shell.
In order to improve the sealing blocked water, the air passing hole on described limit dais is provided with the cambered surface of mating with water blockoff ball surface configuration towards a side margin of water blockoff ball.
Compared with prior art, the utility model has following beneficial effect:
The utility model is novel, make use of the principle that pressure promotes spheroid dexterously, in protection cylindrical shell, water blockoff ball is set, and hold spheroid and air inlet under normal circumstances by bracket, when intaking, hydraulic pressure is greater than gaseous-pressure, water limits from lower promotion spheroid at limit dais, block air passing hole by spheroid simultaneously, effectively prevent water and enter gas path pipe, safe and convenient to use, when hydraulic pressure after failture evacuation reduces, fall of ball makes again air passing hole unimpeded, realize normal air feed, and the utility model structure is simple, design ingenious, with low cost, easy to use, be with a wide range of applications, be applicable to applying.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is the schematic diagram after the utility model is installed in gas circuit.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and mode of execution of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1 to Figure 2; this gas pipeline water-inlet-proof protective gear; comprise the protection cylindrical shell 1 of two ends with the internal thread interface 5 mated with gas pipeline; near the limit dais 2 protruding from protection cylinder inboard wall that one end internal thread is arranged; be connected to the bracket 3 at the other end internal thread place; and to be placed in protection cylindrical shell and water blockoff ball 4 between limit dais and bracket; wherein; limit dais and bracket are equipped with air passing hole 6; the diameter of water blockoff ball is less than the internal diameter of protection cylindrical shell, and is greater than the air passing hole diameter on limit dais.Promote water blockoff ball for the ease of pressure, described water blockoff ball is made up of lightweight material, and lightweight material is also convenient to float on waterborne simultaneously.
Further, described bracket comprises the support body 8 in mating with protection cylinder internal diameter, and is arranged at the outside thread 9 mated outside support body and with the internal thread of protection cylindrical shell, and wherein, air passing hole is arranged on support body.Blocking the air passing hole on bracket at nominal conditions in order to avoid spheroid, staggers mutually in the air passing hole position on described bracket and the air passing hole position on limit dais.In order to not affect ventilation, the quantity of the air passing hole on described bracket is at least two.
In order to effectively intercept water inlet, the air passing hole on described limit dais is coaxial with protection cylindrical shell.In order to improve the sealing blocked water, the air passing hole on described limit dais is provided with the cambered surface 7 of mating with water blockoff ball surface configuration towards a side margin of water blockoff ball.
During use, this water-inlet-proof protective gear 10 can by installing on the gas pipeline after gas meter 11 of registering one's residence shown in Fig. 2, and be positioned on the pipeline to water heater list mouth valve 13, be provided with the front valve 12 of table before gas meter, the pipeline between gas meter and this water-inlet-proof protective gear is connected with to gas cooker list mouth valve 14 by three-way valve; The utility model to be connected in fuel gas pipeline to the pipeline valve of water heater, it is preferably axially vertical and limit dais direction installation upward, under normal state, water blockoff ball is positioned on bracket under self gravitation, and the air passing hole on limit dais and bracket ensure that the normal circulation of combustion gas.When there is gas pipeline water entering accident, at the utility model place, water from bottom to top, now hydraulic pressure is greater than air pressure and pushes away on water blockoff ball, and due to the restriction effect of limit dais, water blockoff ball can not pass through limit dais, but the air passing hole position be stuck on limit dais, and with the cambered surface accurate fit on this air passing hole realizes the shutoff to this air passing hole, ensure that water can not continue to rise and enter follow-up gas pipeline, effectively ensure that the safety of gas pipeline.
Above-described embodiment is only preferred embodiment of the present utility model; restriction not to the utility model protection domain; in every case design principle of the present utility model being adopted, and the change carried out non-creativeness work on this basis and make, all should belong within protection domain of the present utility model.
