Abstract
The utility model discloses a cut-off valve used for carrying out safety guard for liquefied petroleum gas, mainly comprising a valve body, an air inlet passage, an air outlet passage, a thread sleeve, a screw rod, a reset press-button, a three-way hole, a press cap, a valve seat, an inserting piece, and a valve; a spring is arranged in the valve seat. When a rubber tube connected with a pressure regulating device is split or shed, an air path is automatically cut by the utility model; when a membrane of the pressure regulating device is broken and the flow rate of the air exceeds a rated flow rate, the air path is automatically cut by the utility model; after the failure is eliminated and the reset press-button is pressed, the air path can return to normal use.
Description
The utility model relates to valve technology field, especially relates to a kind of cut-off valve that is used for liquefied petroleum gas (LPG) is carried out safety protection.
At present, the valve that is used for transportation of liquefied petroleum gas is that angle valve direct by pressure governor and on the steel cylinder is connected, in case pressure governor diaphragm breakage or pressure governor sealed mouth are malfunctioning, the straight wind of pressure governor will occur, causes high pressure draught to wash out Range switch, and even causes fire.Moreover pressure governor outlet end rubber pipe comes off or breakage also can cause fire.
The purpose of this utility model provides and a kind ofly overcomes the prior art defective, can cut off the gas circuit cut-off valve automatically when the liquefied petroleum air pipe breaks down.
The purpose of this utility model is achieved in that a kind of cut-off valve, it mainly comprises valve body, sealing gasket, seal ring, filter screen, connection nipple, handwheel, one end of valve body has gas-entered passageway, the other end has air outlet adapter and outlet passageway, have the pilot hole that communicates with outlet passageway on the valve body perpendicular to gas-entered passageway one side, pilot hole is built-in with swivel nut, swivel nut is built-in with screw rod, one end of screw rod is fastenedly connected rest button, the two ends of spring act on the inner plane of swivel nut and rest button, be with spring on the external diameter of screw rod, have and outlet passageway on the valve body with respect to swivel nut one side, gas-entered passageway, three through holes that pilot hole communicates, the fastening pressure cap that is equipped with in three through holes, pressure cap is interior towards the fastening valve base that is equipped with of an end of screw rod, be fastenedly connected inserts in the valve base, inserts is built-in with the valve that can slide in inserts, valve base is built-in with spring, and the two ends of spring act on inserts and the valve base.
Owing to adopt technique scheme, when being connected the rubber pipe cracking on the pressure governor or coming off, gas circuit is promptly cut off automatically by the utility model; The pressure governor diaphragm breakage, during gas flow overflow flow setting type, gas circuit is promptly cut off automatically by the utility model; After above-mentioned fault is got rid of, press the reset button that resets, can recover normal use.
Below in conjunction with drawings and Examples embodiment of the present utility model is described in further detail:
Accompanying drawing is the utility model structural representation.
With reference to accompanying drawing, the utility model mainly comprises valve body 1, sealing gasket 2, seal ring 3, filter screen 4, connection nipple 5, handwheel 6, one end of valve body 1 has gas-entered passageway 7, the other end has air outlet adapter 8 and outlet passageway 9, have the pilot hole 10 that communicates with outlet passageway 9 on the valve body 1 perpendicular to gas-entered passageway 7 one sides, pilot hole 10 is built-in with swivel nut 11, swivel nut 11 is built-in with screw rod 12, one end of screw rod 12 is fastenedly connected rest button 13, the two ends of spring 14 act on the inner plane of swivel nut 11 and rest button 13, be with spring 14 on the external diameter of screw rod 12, have and outlet passageway 9 on the valve body 1 with respect to swivel nut 11 1 sides, gas-entered passageway 7, three through holes 15 that pilot hole 10 communicates, the fastening pressure cap 16 that is equipped with in three through holes 15, pressure cap 16 is interior towards the fastening valve base 17 that is equipped with of an end of screw rod 12, be fastenedly connected inserts 18 in the valve base 17, inserts 18 is built-in with the valve 19 that can slide in inserts 18, valve base 17 is built-in with spring 14, and the two ends of spring 14 act on inserts 18 and the valve base 17.
Embodiment: with reference to accompanying drawing.Accompanying drawing is a normal operating condition of the present utility model.Handwheel of the present utility model is connected with the angle valve air outlet of gas cylinder, and outlet passageway is connected with pressure governor, opens cylinder angle valve, and gas circuit is through gas-entered passageway, three through holes, pilot hole, outlet passageway, pressure governor, rubber pipe input kitchen range.In case the rubber pipe on the pressure governor ftractures or comes off, the pressure governor diaphragm breakage, during gas flow overflow flow setting type, valve is picked up by super air-flow, and this moment, valve sealed gas circuit automatically, had reached the purpose of using household liquified petroleum gas safely; After fault is got rid of, press the reset button that resets, valve promptly recovers normal operating condition.
