Abstract
The invention relates to an oil absorbing pipe, and particularly relates to an oil absorbing pipe of an operating valve of a grain pulling wheel, adopting ball heads at the two ends. The oil absorbing pipe comprises the ball heads, spring sheathes and joint cores, wherein the two joint cores are arranged and the first ball head and the second ball head are respectively connected with the two ends of a hose by the two joint cores; the first ball head is provided with three connecting ports, two of the connecting ports are symmetrically distributed, and the other connecting port is vertical to the other two connecting ports; the second ball head is provided with two connecting ports which are vertical mutually; the outer diameter of each joint core is less than the inner diameter of a pipe body, and the joint cores are connected with the hose by adopting a bearing and inserting manner; sleeves are sheathed at the surfaces of the connecting positions of the joint cores and the hose; and the spring sheaths are sheathed at the outer surfaces of the sleeves. The oil absorbing pipe has the advantages that the ball heads are adopted as the joints at the two ends, so that the sealing performance between a pipeline and a hydraulic system and between the pipeline and the operating valve is increased; the spring sheathes are added on the surfaces of the sleeves at the joints of the self hose, so that the hydraulic stress concentration is buffered, the stability of the sleeves is enhanced and the service life of the whole oil absorbing pipe is prolonged.
Description
Technical field
The present invention relates to a kind of fuel sucking pipe, relate in particular to the reel paddle control valve fuel sucking pipe that a kind of two ends adopt bulb.
Background technique
Reel paddle is mainly used on Horizontal type reaping machine or combine harvester cutting table, in order to guide cane, to help and to cut and to clean the ceding of Taiwan, prevents from cutting cane and on cutter, piles up and cause stifled cutter.
In hydraulic pressure and hydraudynamic drive technology, control valve is exactly operating valve or is control valve, has directional control valve, pressure valve, Flow valve etc.Handling is exactly by hydraulic pressure or hydraudynamic drive, makes these valve events, thereby arrives controlling party to the object of (commutation), pressure or flow, and these valves have manual, also have automatically.Control valve is connected with the fuel sucking pipe of hydraulic system, both can realize the running of control valve, because control valve is controlled by hydraulic pressure or hydraudynamic drive, so for the quality of the fuel sucking pipe of control valve with and sealing requirements just high especially, and fuel sucking pipe of the prior art, be generally the screw on simple structure of a conventional hoses of a tube end, pipe two end connectors adopt flanged joint, such fuel sucking pipe is poor sealing not only, and pipeline junction generally adopts bayonet joint, appearance surface cover has sleeve, but only adopt sleeve less stable, only adopt sleeve, and do not establish any protective measure, intensity to sleeve is had relatively high expectations, the working life of sleeve is relatively low comparatively speaking.
Summary of the invention
the problem that 1, will solve
The joint sealing being connected with hydraulic system, control valve for existing fuel sucking pipe is poor, and the stability of the hose coupling of pipeline self also has problem to be strengthened, the invention provides a kind of reel paddle control valve fuel sucking pipe, its two ends adopt bulb joint, increase the sealing between pipeline and hydraulic system, control valve, and at himself hose coupling place sleeve surface increase spring protecting sleeve, buffering hydraulic stress is concentrated, strengthen sleeve stability, improve whole fuel sucking pipe working life.
2, technological scheme
For addressing the above problem, the present invention adopts following technological scheme.
A reel paddle control valve fuel sucking pipe, comprises flexible pipe, the first bulb, sleeve, also comprises the second bulb, spring protecting sleeve and joint core, and described joint core has two, and the first bulb, the second bulb are connected with flexible pipe two ends by two joint cores respectively; The first described bulb is provided with three connection mouths, wherein two symmetrical, another is perpendicular to all the other two; The second described bulb is provided with two orthogonal connection mouths; Described joint core external diameter is less than tube body internal diameter, and adopts bayonet joint with flexible pipe; Described sleeve is placed on the surface, joint of joint core and flexible pipe; Described spring protecting sleeve is placed on sleeve outer surface.
Preferably, described joint wicking surface is all coated with zinc layer.
Preferably, described sleeve is alloy steel piece.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
(1) body employing flexible pipe of the present invention, and flexible pipe two ends connects a threeway bulb by joint core respectively, and one two logical bulb, adopts bulb as the joint between flexible pipe and hydraulic system and control valve, can effectively increase the sealing of flexible pipe.
(2) joint core external diameter of the present invention is less than tube body internal diameter, and adopts bayonet joint with flexible pipe; And cover has sleeve on the surface, joint of joint core and flexible pipe; Sleeve outer surface is provided with spring protecting sleeve; and sleeve is alloy steel piece; sleeve can effectively increase the join strength between joint core and flexible pipe; spring protecting sleeve can play a stress buffer effect to this joint; improve the stability of sleeve; simultaneously also sleeve is played to certain protective role, increase sleeve working life.
(3) joint wicking surface of the present invention is all coated with zinc layer, can effectively prevent that hose coupling and bulb jointing from getting rusty, thereby effectively increases the working life of flexible pipe.
(4) the present invention simple in structure, easy to operate, be easy to manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is side view of the present invention.
Number in the figure explanation: 1, flexible pipe; 2, the first bulb; 3, the second bulb; 4, sleeve; 5, spring protecting sleeve; 6, joint core 6.
Embodiment
For further understanding content of the present invention, below in conjunction with Figure of description and specific embodiment, describe the present invention.
As shown in Figure 1 and Figure 2, a reel paddle control valve fuel sucking pipe, comprises flexible pipe 1, the first bulb 2, sleeve 4, also comprises the second bulb 3, spring protecting sleeve 5 and joint core 6, joint core 6 has two, and the first bulb 2, the second bulb 3 are connected with flexible pipe 1 two ends by two joint cores 6 respectively; The first bulb 2 is provided with three connection mouths, wherein two symmetrical, another is perpendicular to all the other two; The second bulb 3 is provided with two orthogonal connection mouths, adopts bulb as the joint between flexible pipe and hydraulic system and control valve, can effectively increase the sealing of flexible pipe.
As a kind of optimal way, joint core 5 surfaces of flexible pipe 1 two ends connecting ball head are all coated with zinc layer.Zinc layer can effectively prevent that hose coupling and bulb jointing from getting rusty, thereby effectively increases the working life of flexible pipe.
During use, directly the first bulb 2 is connected with the inlet port of reel paddle control valve, the second bulb 3 is connected with the inlet port of hydraulic system, can realize the oil suction of fuel sucking pipe.Wherein the first bulb 2, the second bulb 3 all can effectively guarantee the sealing that two ends inlet port connects; Alloying steel sleeve 4 outsides are provided with spring protecting sleeve 5; increase the join strength between joint core 6 and flexible pipe 1; spring protecting sleeve 5 can play a stress buffer effect to this joint; improve the stability of sleeve 4; strengthen the protection of 4 pairs of flexible pipes 1 of sleeve; can effectively avoid flexible pipe to occur the phenomenons such as breakage, cracking, flexible pipe improves for 1 working life greatly, and the while also can increase by 4 working lifes of sleeve.
