Oil absorbing pipe of operating valve of grain pulling wheel

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 [0001] The present invention involves a kind of oil absorption pipe, especially involving a pumping wheel manipulating valve absorption pipe using the ball head at both ends. Background technique [0002] The pull -up wheel is mainly used for the crooked harvester or the combined harvester cutting table to guide the stem poles, support the cutting, and clean the table to prevent the stem rods from accumulating the cutting knife and cause the sword. [0003] In the hydraulic and hydraulic transmission technology, the manipulating valve is the operating valve or the control valve, with the direction valve, pressure valve, flow valve, etc.The manipulation is the purpose of driving the valve through hydraulic or hydraulic force to reach the purpose of the control direction (deduction), pressure or flow. These valves are manual and automatic.Connect the fuel -absorbing pipe of the manipulating valve with the hydraulic system, which can achieve the operation of the mani...

Problems solved by technology

[0005] Aiming at the problem that the existing oil suction pipe is poorly sealed at the joint connected with the hydraulic system and the control valve, and the stability of the hose joint of the pipeline itself needs to be strengthened, the present invention provides an oil suction pipe for the reel control valve, Ball joints are used at both ends to increase the tightness between the pipeline and the hydraulic system and the control valve, and a spring sheath is added to the surface of the sleeve at its own hose joint to buffer the hydraulic stress concentration, enhance the stability of the sleeve, and improve the stability of the sleeve. The entire service life of the suction pipe
