Abstract
The utility model relates to a gas valve of the low pressure cylinder for the liquid fuel, which is a valve used for controlling the low pressure cylinder for the liquid fuel to vent the gas, comprising a hand wheel, a valve body and a conduit. The valve body is provided with a press air joint and a heating gas outlet; the actions of the existing gas-phase valve and liquid phase valve are merged at one valve body via a connecting sleeve and a pipe sleeve; the connecting sleeve with press air holes and heating gas holes is arranged in the valve body; the pipe sleeve is sheathed in the connecting sleeve. The utility model has the advantages of convenient operation and high reliability and simplifies the structure of the steel cylinder at the same time.
Description
The utility model liquid fuel low pressure Steel cylinder gas valve relates to a kind of control gear of discharging gas in the pressurized container, specifically a kind of controlling liquid fuel low pressure steel cylinder is discharged the valve of gas, form by handwheel, valve body and conduit, the valve body lower end spinning is fixed on the steel cylinder top, and conduit is in steel cylinder.
The device that gas is discharged in existing a kind of liquid fuel low pressure steel cylinder control is to be divided into the valve that gas valve and two spinnings of liquid phase valve are fixed on the steel cylinder top, inconvenient operation, the keying of gas valve and liquid phase valve wants strictness to carry out in proper order in accordance with regulations, steel cylinder is made also more complicated simultaneously, and two valve seats that gas valve and liquid phase valve are installed are set.
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, design a kind of novel liquid fuel low pressure Steel cylinder gas valve, gas valve and liquid phase valve are integrated, easy to operate, also can simplify simultaneously the manufacturing of liquid fuel low pressure steel cylinder, only a valve seat need be set and get final product.
The utility model liquid fuel low pressure Steel cylinder gas valve is made up of handwheel, valve body and conduit, the valve body lower end spinning is fixed on the steel cylinder top, conduit is in steel cylinder, the technical measures that realize the utility model purpose are: valve body lower portion is provided with the joint of calming the anger, gas outlet is arranged on valve body top, handwheel is fixedly mounted on the valve rod of valve body upper end, and the valve rod lower end is connected with the valve pad of spinning in valve body through connecting plate; Valve body lower end is installed with a connecting sleeve, in valve body, has a pipe box to be sleeved in the connecting sleeve, and a spring is arranged between pipe box and the connecting sleeve; Conduit upper end spinning is being connected on the connecting sleeve lower end and with the hole of calming the anger that is provided with on the connecting sleeve sidewall, and the fuel gas hole that is provided with on pipe box and the connecting sleeve is connected.
When using the utility model liquid fuel low pressure Steel cylinder gas valve on the liquid fuel within low pressure steel cylinder, only a valve seat need be set on the steel cylinder, the conduit of the utility model liquid fuel low pressure Steel cylinder gas valve is inserted in the steel cylinder, and the valve body lower end spinning is fixed on the valve seat on steel cylinder top and gets final product.During the liquid fuel (this air valve is in closed condition) that in needs use steel cylinder, injected, to calm the anger earlier joint and pressurized air source connected, gas outlet and burner are connected, press the opening direction rotation hand wheel then, revolve by valve rod and connecting plate and to move back valve pad, pipe box is up under spring force, make source of the gas compressed and supplied gas through the joint of calming the anger, the hole of calming the anger on the connecting sleeve, again in the liquid fuel in conduit is pressed into steel cylinder, make liquid fuel gasification, continue rotation hand wheel, pipe box continues to go upward to upper position-arresting postpone under spring force, valve rod only drives valve pad through connecting plate and continues to revolve and move back, thereby the fuel gas hole on the connecting sleeve is communicated with gas outlet through pipe box, and the gasification burning in the steel cylinder can be through fuel gas hole, pipe box and gas outlet are delivered to burner and are lighted use.When needs are closed combustion gas, press closing direction turn handwheel, by valve rod and connecting plate precession valve pad, after joining, valve pad and pipe box promptly close gas outlet, continue the precession handwheel, it is descending that valve pad promotion pipe box overcomes spring force, and the hole path of calming the anger on calm the anger joint and the connecting sleeve is blocked, the source of the gas pressurized gas promptly can not enter steel cylinder, and liquid fuel low pressure steel cylinder is in buttoned-up status.In sum, the structure of the utility model liquid fuel low pressure Steel cylinder gas valve is incorporated in the effect of prior art gas valve and two valves of liquid phase valve on the valve body and has realized, the structure easy to operate, reliable, that the while has also been simplified steel cylinder has realized the purpose of this utility model preferably.
Further specify a utility model liquid fuel low pressure Steel cylinder gas valve and an one embodiment's structure below in conjunction with accompanying drawing.
Accompanying drawing is a utility model liquid fuel low pressure Steel cylinder gas valve and an one embodiment's a structural representation.
As shown in drawings, the utility model liquid fuel low pressure Steel cylinder gas valve is by handwheel 1, valve body 18 and conduit 12 are formed, valve body 18 lower end spinnings are fixed on steel cylinder 15 tops, conduit 12 is in steel cylinder 15, as an embodiment, the utility model liquid fuel low pressure Steel cylinder gas valve is: valve body 18 bottoms are provided with the joint 17 of calming the anger and can be connected with compressed gas source, the gas outlet 5 that is connected with burner is arranged on valve body 18 tops, handwheel 1 is fixedly mounted on the valve rod 2 of valve body 18 upper ends, valve rod 2 lower ends are connected with the valve pad 4 of spinning in valve body 18 through connecting plate 3, and this kind structure brings convenience for the dismounting air valve; Valve body 18 lower ends are installed with a connecting sleeve 11, in valve body 18, have a pipe box 7 to be sleeved in the connecting sleeve 11, and a spring 10 is housed between pipe box 7 and the connecting sleeve 11; Conduit 12 upper end spinnings are being connected on connecting sleeve 11 lower ends and with the hole 9 of calming the anger that is provided with on connecting sleeve 11 sidewalls, the fuel gas hole 16 that is provided with on pipe box 7 and the connecting sleeve 11 is connected, this kind structure can guarantee reliably that pressurized gas and combustion gas are isolated fully in valve body 18.
For prevent in the steel cylinder 15 liquid fuels from conduit 12 lower ends through conduit 12, calm the anger hole 9 and joint 17 adverse currents of calming the anger to compressed gas source, generally can on calm the anger joint 17 and compressed gas source connecting pipeline, set up a reverse stop valve, also can be as shown in drawings, also be provided with a check valve pocket 13 in said conduit 12 lower ends, device has check valve piece 14 in check valve pocket 13, structure is simple, reliable, said check valve piece 14 can be a ball bead, can cooperate fully with the circular cross-section of conduit 12, the tight degree of check is better.
Close fuel gas path and prevent the degree of reliability that last pressurized gas enters pipe box 7 for raising valve pad 4 contacts with pipe box 7, as shown in drawings, the lower end that is preferably in said valve pad 4 is inlaid with resilient pad 6(such as nylon pad), on said pipe box 7, also be set with sealing gasket 8.
