Abstract
The utility model relates to a dualpurpose tube fuel gas dedicated switch, comprising an assembly shell, wherein a vent pipe is arranged in the shell; one end of the vent pipe is of a gas inlet end, and the other end of the vent pipe is of a gas outlet end; a valve core rotating rod is arranged in the shell, and the valve core rotating rod is matched with a valve core spiral rod through a screw cap; one end of the valve core rotating rod is connected with a spiral handle, and the other end thereof is matched with a rubber valve core sealing sleeve; the two ends of the vent pipe are of bell socket reducer pipes, and threaded casings are arranged outside the bell socket reducer pipes; the bell socket reducer pipes are connected with the threaded casings through screw caps, and a cone-shaped sealing ring is arranged in the screw cap of the threaded casing; and the vent pipe is of a horizontal straight-way-type structure or a 90-degree intersection angle structure. Through the structure that the reducer pipes are arranged at the two ends of the vent pipe, the switch can be suitable for connecting pipes with two different specifications, thereby expanding the range of use; and the valve core rotating rod and the rubber valve core sealing sleeve can make the switch have good sealing performance, the service life is long, the switch is safe and reliable, and the service life is more than 15,000 times under 20KPa air pressure.
Description
Technical field
The utility model relates to a kind of combustion gas switch, particularly a kind of dual-purpose pipe combustion gas special switch that is suitable for two kinds of different sizes connection tubing.
Background technique
General gas control switch is single caliber, can only be applicable to a kind of connection tubing, its sealing configuration principle has spherical valve core, ceramics spool, taper valve core, the combination of flat rubber sheet spool to compress, and this type of switch is used for defectives such as fuel gas corrosion proof, durability and sealing difference
Summary of the invention
The purpose of this utility model is will provide a kind of to connect tubing, the dual-purpose pipe combustion gas special switch with good anti-corrosive properties, durability and sealing applicable to two kinds of specifications.
The purpose of this utility model is achieved in that a kind of dual-purpose pipe combustion gas special switch, comprise assembly shell, be provided with breathing pipe in the housing, breathing pipe one end is an inlet end, one end is the outlet side, be provided with the spool swingle in the housing, the spool swingle matches with spool screw rod nut, spool swingle one end is connected with spiral handle, the other end matches with rubber spool stuffing box gland, is the socket reducer pipe by the pipe two ends, and the socket reducer pipe is provided with threaded sleeve outward, the socket reducer pipe is connected with the threaded sleeve nut, is provided with conical seal ring in the threaded sleeve nut.Breathing pipe is the straight horizontal formula or has 90 corner formula structures.
The dual-purpose pipe combustion gas special switch that the utility model provides by the structure of reducer pipe is set at the breathing pipe two ends, makes the connection tubing of switch applicable to two kinds of different sizes, has enlarged using scope; Spool swingle and rubber spool stuffing box gland can make switch have good sealing, and long service life is safe and reliable, and in 20KPa air pressure, working life is above 1.5 ten thousand times.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model breathing pipe when being the straight horizontal general formula.
Fig. 2 is the structural representation of the utility model breathing pipe when having 90 corners.
Embodiment
The utility model adopts following structure: comprise assembly shell 1, be provided with breathing pipe 10 in the housing 1, breathing pipe 10 1 ends are inlet end 11, one end is outlet side 12, be provided with spool swingle 3 in the housing 1, spool swingle 3 matches with spool screw rod nut 4, spool swingle 3 one ends are connected with spiral handle 6, the other end matches with rubber spool stuffing box gland 2, by managing 10 two ends is socket reducer pipe 7, be provided with threaded sleeve 6 outside the socket reducer pipe 7, socket reducer pipe 7 is connected with threaded sleeve nut 9, is provided with conical seal ring 8 in the threaded sleeve nut 9.
The utility model breathing pipe 10 adopts two kinds of structural types, and the one, breathing pipe 10 is the straight horizontal formula, inlet end 11 and outlet side 12 are interchangeable; Another kind is that breathing pipe 10 has 90 corner formula structures, inlet end 11 and outlet side 12 fixed-site.
Working principle of the present utility model is as follows: combustion gas enters breathing pipe 10 from inlet end 11, twisting spiral handle 5, and spool screw rod 3 produces and moves, and compresses the heel of rubber spool stuffing box gland 2, and switch is in closed condition; To counter-rotation spiral handle 5, spool screw rod 3 moves up, and unclamps rubber spool stuffing box gland 2, and switch then is in out the valve state.
Hard tube material that the external diameter specification is identical with threaded sleeve 6 internal diameters or semihard tubing are inserted in the heel of threaded sleeve 6 from conical seal ring 8 holes, threaded sleeve nut 9 is tightened, and is promptly salable by conical seal ring 8 locking tubing.
The internal diameter specification is inserted in socket reducer pipe 7 external diameter heels with the identical flexible pipe of socket reducer pipe 7 external diameters from the hole of conical seal ring 8, threaded sleeve nut 9 is tightened, and is promptly salable by conical seal ring 8 locking tubing.
