Problems solved by technology

[0004] However, it has been found through practical application that the above-mentioned "forklift hydraulic pipeline tee joint" also has the following disadvantages: first, since the oil hole 111' is arranged on the side wall of the slide valve 11', when the slide valve 11' is connected to the joint When the body 1' moves inside, the oil hole 111' contacts the inner wall of the joint body 1', and the oil cylinder interface 10' of the joint body 1' is temporarily closed, so that the hydraulic oil in the lifting cylinder cannot enter the joint body 1', resulting in the entire three The short-term interruption of the oil circuit through the joint affects the normal operation of the entire hydraulic pipeline; second, in order to ...

Abstract

The invention discloses a novel forklift hydraulic pipeline tee joint. The novel forklift hydraulic pipeline tee joint comprises a joint body which is provided with an oil cylinder connecting opening; a sliding valve is flexibly arranged in the oil cylinder connecting opening; the cylindrical wall of the oil cylinder connecting opening is provided with a rear external thread section and a front external thread section; the end portion of the oil cylinder connecting opening extends to form a small diameter connection portion which is matched and connected with an end cover; the sliding valve comprises a base and a valve body; the base is arranged in the oil cylinder connecting opening; the valve body is formed and arranged on the base; the side wall of the valve body is provided with a first oil hole; the end portion of the valve body is provided with a second oil hole; the first oil hole and the second oil hole are formed in a communicated mode; the rear external thread section is formed by left-hand threads and right-hand threads which are arranged correspondingly and matched with each other; the rear external thread section is provided with a fastening nut and a locking nut. According to the novel forklift hydraulic pipeline tee joint, the structure is simple and reasonable, the high pressure impact on the joint of the hydraulic oil can be avoided, the normal work of a hydraulic pipeline can be ensured, the sliding valve is high in action sensitivity, and the sealing effect is good.

Description

technical field [0001] The invention relates to the technical field of forklift hydraulic pipeline connection, in particular to a novel forklift hydraulic pipeline tee joint. Background technique [0002] Forklifts are widely used in the machinery industry because they are more convenient to carry goods, and are well known and common by the public. Forklifts mainly use a hydraulic system to provide the power to move goods, so the hydraulic system of forklifts needs to have high reliability. Since the hydraulic system of the forklift is connected through many pipelines, and the connection directions and positions of the pipelines are different, many joints need to be used for switching. When the forklift moves the goods, there will be a large instantaneous pressure in the pipeline, which will cause a large impact on the pipeline, especially the impact on the pipeline joint. If the pipeline joint is subject to instantaneous impact for a long time, it may cause damage. The jo...
