Description
The utility model relates to the valve of a kind of dining room, industrial liquefied petroleum ga steel cylinder or liquid fuel container, particularly a kind of can control gaseous and the special valve of liquid two-phase fuel compatible.
LP gas cylinder needs in the bottle can or discharges gas phase petroleum gas in using production process, also needs drain or Residual oil in the bottle sometimes, and therefore only the valve of use with a valve port, a handwheel do not reach use, production requirement.For this reason, the patent No. is 88213737.9 to disclose a kind of gas, liquid fuel with the two-way valve of using, this valve is provided with valve body, two mechanisms of the row of being provided with, aeration phase and liquid phase fuel on this valve body, promptly be respectively equipped with liquid phase valve and gas valve and control handwheel thereof, the axis of its valve body becomes " Y " font, and core pipe coaxial with valve body and that communicate with liquid phase valve and long tube are housed in the bottom of this valve body, is provided with the annular space that communicates with gas valve between this valve body and core pipe.When needs use liquid fuel or discharging Residual oil, only drive the liquid phase valve handwheel that stands on angle valve top, liquid just is expelled to outside the valve along long tube, core pipe by means of the air pressure that remains in the bottle.When needs are used gas phase fuel, only open the gas valve handwheel of side, gaseous fuel can enter outside the gas phase valve port amount discharge container by the annular space between valve body and the core pipe.Therefore, this valve is under the inverted situation without steel cylinder, be convenient to discharge liquid and gaseous fuel, be convenient to discharge Residual oil, also be convenient to install and operation, and two mechanisms work respectively, do not disturb mutually, also there is following shortcoming in this valve simultaneously: 1, owing to can produce phenomenons such as vibration and fluid rock in transportation process, and can cause the connection part of core pipe and long tube loosening or rupture, influence the normal discharging of liquid fuel or Residual oil.2, easily stifled long tube of the residue in the bottle or core pipe, also influence is normal uses.3, because liquid phase valve and gas valve do not have the visible marking, cause misoperation easily.
The purpose of this utility model provides a kind of gas, liquid fuel double-purpose angle valve, and this angle valve is simple in structure, easy to operate, is difficult for breaking down, under the vibration situation, also can normally use, and long service life, and be not easy to produce misoperation.
The utility model is realized by following manner.This gas, liquid phase fuel double-purpose angle valve, this angle valve is provided with valve body, the row of being provided with on this valve body, two mechanisms of aeration phase and liquid phase fuel, promptly be respectively equipped with liquid phase valve and gas valve and control handwheel thereof, the axis of this valve body becomes " Y " font, annular distance center in this valve body is provided with conduit coaxial with this valve body and that communicate with described liquid phase valve, between this valve body and described conduit, be provided with the annular space that communicates with described gas valve, anti-vibration sleeve is equipped with in the bottom of described valve body, and this anti-vibration sleeve is set on the described conduit, has the vent cap that communicates with described annular space on the jacket wall of this anti-vibration sleeve.When needs use liquid fuel or discharging Residual oil, only drive the handwheel of the liquid phase valve that stands on angle valve top, the air pressure that liquid thereby helps remain in the bottle is outside conduit is expelled to valve.When needs are used gas phase fuel, only open the handwheel of the gas valve of side, the vent cap on the anti-vibration sleeve that gaseous fuel is provided with by valve body lower portion enters the gas phase valve port, outside the amount discharge container.This valve is convenient to discharge Residual oil need not with steel cylinder under the inverted situation, being convenient to discharge liquid and gaseous fuel, also is convenient to install and operation.Two gas, the valve work of liquid mechanism are mutually in disturbing.This valve is difficult for being damaged under the vibration situation that is produced in the middle of the transportation, can normally use long service life.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a gas, liquid fuel double-purpose angle valve A type section of structure
Fig. 2 is a gas, liquid fuel double-purpose angle valve Type B section of structure
As shown in Figure 1 and Figure 2, gas, liquid fuel double-purpose angle valve includes and is arranged on liquid phase valve and handwheel 11, gas valve and the handwheel 13 thereof that is mutually several angle on the valve body 4, and wherein liquid phase valve and valve body 4 and conduit 2 are on same axis.The bottom of conduit 2 upper ends and liquid phase valve is to be threaded.Be provided with filter 1 in the lower end of described conduit 2.In the bottom of valve body 4 anti-vibration sleeve 3 is housed, and with screw thread and valve body 4 lockings, conduit 2 strings are through in the center hole of anti-vibration sleeve 3.Anti-vibration sleeve 3 can prevent in transportation process phenomenon generations such as the loosening or fracture of the connection part that causes conduit 2 upper ends owing to rocking of vibration and fluid.The side face corresponding section of anti-vibration sleeve 3 has four road vent caps, these vent caps and formed annular space, valve body 4 centers, and gas valve communicate.Valve 5 and valve body 4 are to be threaded, its top has a rectangle groove corresponding with the rectangle groove that revolves axle 7 bottoms, have rectangle flap 6 to be inserted in wherein, the rotation along with the handwheel 11 of liquid phase valve can drive valve 5 and move up and down, also promptly open or close, liquid is when discharging, and liquid is introduced into filter 1 along the direction of A and filters, then through conduit 2, pass through the valve port of liquid phase valve at last, discharge along the direction of arrow B indication.
As shown in Figure 1 and Figure 2, filter 1 can adopt the hollow tetragonal body, and filter screen is equipped with at the four sides of the left, right, front and rear of hollow tetragonal body, is connected with conduit 2 above it.Liquid can enter conduit 2 by filter screen, thereby filters.
Gas valve of the present utility model is provided in a side of the inclination position on the valve body 4, and its structure and Component size and above-mentioned liquid phase valve are identical, just the passage difference.As shown in Figure 1 and Figure 2, the vent cap on 3 enters annular space between valve body 4 and the conduit 2 to gas along the C direction from anti-vibration sleeve, passes through the valve port of gas valve again, discharges along the direction of arrow D indication.
In order to prevent misoperation, on the handwheel of described gas valve red coatings is arranged, " gas phase " printed words are carved with in recess position in the middle of it; Green or blue coating are arranged on the handwheel of described liquid phase valve, and " liquid phase " printed words are carved with in recess position in the middle of it.
Fig. 1, Fig. 2 are gas, liquid fuel double-purpose angle valves.Its basic structure is the same, and just Fig. 1 is a liquid phase fuel double-purpose angle valve A type structure, and the locking cap 8 of its liquid phase valve and gas valve is built-in type, and locking cap 8 is locked on liquid phase valve or the gas valve by sealing gasket 9, and the locking body of locking cap 8 is in valve body.Fig. 2 is a gas phase fuel double-purpose angle valve Type B structure, and the locking cap 8 of its liquid phase valve and gas valve is external mounted, and locking cap 8 is locked on liquid phase valve or the gas valve by sealing gasket 9, and the locking body of locking cap 8 is outside valve body.
As shown in Figure 1 and Figure 2, the handwheel 11 of liquid phase valve and the handwheel 13 of gas valve are to be contained in by screw 12 respectively to revolve on the axle 7, and are furnished with O type seal ring 10.
Main Component of the present utility model, as valve body 4, valve 5, revolve the axle 6 and anti-vibration sleeve 3 all adopt HP
