Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] Such as figure 1 The hydraulic line switchgear shown includes top operating shaft 1, cylindrical barrel 2, accumulator 9, upper piston 10, lower piston 12, isolation piston 14, spring base 34, outer cylindrical barrel 39, pressurized Spring 41, port plug 44, lower actuator rod 55, hydraulic gate pipe joint 58. The upper piston 10 and the top operating shaft 1 are coupled together through threads 16 .

[0040] Wherein, the top manipulation shaft 1 can freely slide up and down in the cylindrical barrel 2 . An isolating piston 14 is placed between the cylindrical barrel 2 and the upper piston 10 . A hydraulic cavity 20 is formed between the upper piston 10 , the top operating shaft 1 and the cylindrical barrel 2 . A high-pressure oil chamber 15 is formed between the isolation piston 14 and the lower piston 12 . A low-pressure air chamber 23 is formed between ...

Abstract

The invention provides a switching device of a hydraulic circuit. The device comprises an operating shaft, a cylinder, an energy accumulator and an outer cylinder body, the energy accumulator is connected with the cylinder, the cylinder is arranged in the outer cylinder body, a hydraulic cavity is formed in the part between the operating shaft and the cylinder, an isolation piston is arranged between the outer side of the lower portion of the upper piston and the cylinder, a low-pressure air cavity is formed in the part between the upper portion of the isolation piston and the cylinder, a high-pressure oil cavity is formed in the part between the lower portion of the isolation piston and the lower portion piston, a hole passage is formed in the middle of the upper portion piston, the hydraulic cavity is communicated with the high-pressure oil cavity through the hole passage, the bottom of the upper portion piston is connected with the lower portion piston, the outer ring of the bottomof the cylinder is provided with a spring base, a compressed spring is arranged below the spring base, the lower portion of the lower piston is connected with a lower executing rod, and the bottom ofthe lower executing rod extends into the pipe joint of a hydraulic valve.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil circuits, in particular to a switch device for hydraulic oil circuits. Background technique [0002] The hydraulic oil circuit switch device is used in each branch pipeline of the hydraulic oil circuit to close or open the hydraulic circuit, but the existing oil circuit switch usually requires a lot of force to be manipulated by the operator. In industrial production or practical application, there is no hydraulic oil circuit switch device that can be manipulated with only a small force, and the operator can make it open or close the oil circuit. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide a switch device for the hydraulic oil circuit in view of the deficiencies of the prior art. [0004] In order to solve the above-mentioned technical problems, the present invention provides a switchgear for a hydr...
