Background technique
In the prior art; safety cut-off is carried out at the natural gas station for the air pressure of balance combustion gas and when the overpressure; pressure governor has been installed on gas pipeline; be used for regulating automatically the pressure of combustion gas and excess pressure cutout protection (pressure governor structure can referring to the disclosed gas pressure regulator, governor of CN2432411Y); but owing in long-term using process, can cause the valve rod of pressure regulation dish; flap is dirty aging; epithelium is aging damaged; signal tube stops up; the generation of situations such as the spring rust is mashed; in time keep in repair or change if fail; when pressing string low pressure during the capital causes; cut-off valve reaction on the pressure governor is slow in one's movements; can't carry out the cut-out of combustion gas, cause gas leakage, blast accident takes place.
The model utility content
The purpose of this utility model just provides a kind of combustion gas fast shut-off device that can cut off fast when the gaseous-pressure superpressure.
The purpose of this utility model is to realize by such technological scheme, a kind of combustion gas fast shut-off device,: described shut-off means comprises shell, be provided with the gas passage in the enclosure, shell is provided with and gas-entered passageway and the outlet passageway of crossing the gas channel connection, one end of shell is provided with and the signal tube of crossing the gas channel connection, is provided with the transversely cutting valve described the mistake in the gas passage, is provided with the ball cut-off valve in described outlet passageway.
Further, described transversely cutting valve comprises transversely cutting bar on the sealing rubber base end face that is arranged on pressure governor cut-off valve valve rod, was arranged on the dividing plate of gas channel middle, dividing plate is provided with air passing hole, and the diameter of described transversely cutting bar is less than the aperture of air passing hole.
In order to prevent that the impurity in the combustion gas from entering into outlet passageway, described air passing hole is a cone shape hole, and its big mouthful towards outlet passageway.
Further, above-mentioned ball cut-off valve comprises spool, is provided with ball in spool, and an end end of spool is provided with the bounding means A that has air outlet hole A, and the end arm of the other end of spool is provided with opening.
When preventing that spool is subjected to high pressure, break away from outlet passageway, in described outlet passageway, be provided with the bounding means B that has air outlet hole B, described bounding means B is positioned at the upper end of spool.
In order to prevent that spool from rotating in crossing the gas passage, be provided with location piece described the mistake in the gas passage, the lower end surface of described spool is provided with locating slot, and described location piece matches with locating slot.
Owing to adopted technique scheme, the utlity model has structural design ingenious, simple advantage is installed, adopt it under the situation of superpressure, fast combustion gas to be cut off, played safety effect.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is the structural representation of the utility model user mode;
Fig. 2 is an A-A sectional structure schematic representation among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of combustion gas fast shut-off device, described shut-off means comprises shell 1, in shell 1, be provided with gas passage 2, shell 1 is provided with and crosses gas-entered passageway 3 and the outlet passageway 4 that gas passage 2 is communicated with, one end of shell 1 is provided with and crosses the signal tube 5 that gas passage 2 is communicated with, and is provided with the transversely cutting valve described the mistake in the gas passage 2, is provided with the ball cut-off valve in described outlet passageway 4.
Wherein, above-mentioned transversely cutting valve comprises transversely cutting bar 9 on sealing rubber base 8 end faces that are arranged on pressure governor 6 cut-off valve valve rods 7, was arranged on the dividing plate 10 at gas passage 2 middle parts, dividing plate 10 is provided with air passing hole 11, and the diameter of described transversely cutting bar 9 is less than the aperture of air passing hole 11; Described air passing hole 11 is a cone shape hole, and its big mouthful towards outlet passageway 4.
Above-mentioned ball cut-off valve comprises spool 12, is provided with ball 13 in spool 12, and an end end of spool 12 is provided with the bounding means A15 that has air outlet hole A14, and the end arm of the other end of spool 12 is provided with opening 16.
The utility model is to use like this: the utility model is to cooperate practicality with pressure governor 6, the cut-off valve valve rod 7 of pressure governor 6 was penetrated in the gas passage 2, again pressure governor 6 and the utility model are fixed by flange plate, the other end of signal tube 5 is connected with pressure governor signal suction port, get final product.Under normal circumstances, combustion gas enters from gas-entered passageway 3, enters in the way 4 of giving vent to anger by air passing hole 11, enters into the combustion gas gas meter from outlet passageway 4 at last.When combustion gas air pressure is too high, combustion gas passes to pressure governor 6 by signal tube 5 with the information of overpressure, the cut-off valve valve rod 7 of pressure governor 6 stretches into to outlet passageway 4, make seal rubber pad 8 that air passing hole 11 is stopped up, simultaneously, the balls 13 in the spool 12 move up air outlet hole A14 are stopped up, and transversely cutting bar 9 stretches into and is positioned at ball 13 belows in the spool 12 ball 13 is withstood, ball 13 can not be resetted, so just reached the purpose of fast shut-off combustion gas.When needs reset, get final product with pulling moving cut-off valve valve rod 7.
When the user under high pressure is registered one's residence not eliminating situation of dangerous situation, with pulling moving cut-off valve valve rod 7, at this moment, the balls 13 in the spool 12 still are subjected to the promotion of pressurized gas, and air outlet hole A14 is stopped up, and have so just avoided the secondary generation of dangerous situation.
In order to limit and locate spool, in described outlet passageway 4, be provided with the bounding means B18 that has air outlet hole B17, described bounding means B18 is positioned at the upper end of spool 12; Be provided with location piece 19 described the mistake in the gas passage 2, the lower end surface of described spool 12 is provided with locating slot 20, and described location piece 19 matches with locating slot 20.
