Abstract
The utility model relates to a valve for a steel bottle for liquefied petroleum gas, which is the improvement of the existing valve for the steel bottle and is used for solving the problem of the combustion of raffinate in the steel bottle. The valve for a steel bottle comprises a valve body, a baffle plate and a handle, wherein a component which is provided with an air outlet hole with variable diameter, a hole for a liquid catheter, the liquid catheter inserted on the hole for the liquid catheter and a one-way circulation liquid inlet hole is installed in the valve body, wherein the outlet of the liquid catheter is formed at the thinnest part of the air outlet hole. The valve can realize the purposes of raffinate elimination and energy conservation.
Description
The utility model relates to a kind ofly can make the device that volatile liquid fuel and difficult volatilised liq fuel burn simultaneously in the container, especially uses on oil liquefied gas steel cylinder, can make the valve that does not stay raffinate in the bottle after the gaseous combustion.
The valve that uses on the liquefied petroleum ga steel cylinder, can only allow the petroleum gas of vaporization flow out, and the long-chain higher boiling product that is difficult for vaporization can not flow out, final residual is at the bottom of bottle, make troubles to the user, also wasted the energy, if raffinate is poured over field or sewerage, will polluted soil, water source, air, serious also will cause blast on fire.
The purpose of this utility model provides and a kind of easy gasifying liquid and difficult gasifying liquid in the liquefied petroleum ga steel cylinder together flowed out, and does not stay the valve of raffinate in the bottle.
The purpose of this utility model is achieved in that existing steel cylinder valve mainly is made of valve body, baffle plate, handle, and valve body has suction port and air outlet.The utility model is that valve body is partly improved, and increases by parts in valve body, has several holes on these parts.One is an air outlet hole, and this hole is a reducing; It two is the drain pore, on this hole catheter is housed, and the catheter outlet port is at the thinnest place of air outlet hole.Because air outlet hole is reducing, so when gas flows out, flow velocity is in change, pressure is also in change, and is the fastest at the gas flow rate at the thinnest place in this hole, the pressure drop maximum.By the effect of pressure reduction, the liquid of outlet port in the catheter at the thin place of Kongzui of giving vent to anger will rise.And the together spouting and atomizing of expanding with high velocity air, atomized drop is transported to the burner vaporization for combustion under the drive of air-flow.Also have an inlet opening in addition, this hole is unidirectional, when promptly just thinking in steel cylinder the packing fluid gasification, opens under pressure, closes when giving vent to anger.
Parts and valve body in the valve body of the present utility model can be made into one, also can manufacture respectively, by being threaded togather.
Advantage of the present utility model is: can make the whole after-flames of liquid gas in the bottle, do not stay raffinate, solve the user and thirsted for the problem that solves for a long time, reduce loss, save the energy, have remarkable social benefit and economic benefit.
Description of drawings:
Fig. 1 is the utility model embodiment sectional view.
Fig. 2 is the plan view of the utility model embodiment parts.
Fig. 3 is the revolved sectional view of the utility model embodiment parts.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Fig. 1 described the utility model embodiment structure and with the situation that is connected of steel cylinder, this valve is made of valve body 1, baffle plate 2, handle 3 and inner parts 4, wherein parts 4 adopt screw thread to be connected with valve body 1, whole valve is assemblied on the steel cylinder 5, Fig. 2 and Fig. 3 have described the structure of valve body 1 inner piece 4, have inlet opening 6 on parts 4, and this hole is sealed from the bottom by ball 7, spring 8 is arranged below the ball 7, a hollow screw 9 is housed below the spring 8.When the filling liquid gasification, under pressure, ball 7 descends, and inlet opening 6 is opened, and liquid gas flows into.Also have drain pore 12 and air outlet hole 15 on the parts 4, drain pore 12 close-fittings have catheter 13, and air outlet hole 15 is hole, a diminishing from top to bottom garden, and the outlet 11 of catheter 13 is in outlet 10 places of air outlet hole 15, and its end opening is inserted in the steel cylinder bottom.When gas when air outlet hole 15 flows out, flow velocity is accelerated, and arrives 10 o'clock flow velocity maximums of outlet, pressure drop this moment is also maximum.At this moment the liquid in the catheter 13 rises to outlet 11 places under the double action of capillary and pressure reduction, under the drive of high velocity air, enter in the vaporizing chamber 14, expand and atomize, and be transported to burner burning through reduction valve, thereby the high boiling liquid at the bottom of making bottle burns simultaneously with easy gasifying liquid, does not stay raffinate in the bottle.
