Embodiment Construction

[0046] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0047] A common two-way plug, such as figure 2 As shown, the two ends connected with the oil pipe can be threaded, or can be ferrule type, flared sleeve, flared nut and other types like ordinary pipe joints, and the middle part is set as a closed structure.

[0048] An electronically controlled two-way plug, such as image 3 As shown, it is a 2-position, 2-way solenoid valve, and the opening and closing of the plug can be controlled by electrical signals.

[0049] The above-mentioned two-way plugs can be applied to hydraulic system debugging. Electronically controlled two-way plugs with automatic intermediate sealing function are installed at each key component of the hydraulic system, and the hydraulic system is debugged by turning on and off the state of the electronically controlled two-way plugs. When working normally, the two-way plug i...

Abstract

The invention relates to a bidirectional choke plug. The middle of the bidirectional choke plug has an enclosed structure which has opening and closing functions; the opening and closing functions of the enclosed structure of the bidirectional choke plug are controlled by an electric signal; the bidirectional choke plug is an electromagnetic valve; and the bidirectional choke plug is a two-position two-way electromagnetic valve. The bidirectional choke plug has simple structure and convenient manufacture, and can separately debug a certain executive device in a hydraulic system with a parallel connection structure when other executive devices work normally. The electrically controlled bidirectional choke plug also can further simplify the debugging work and save the work of detaching pipelines required by debugging.

Description

technical field [0001] The invention relates to a connecting piece, in particular to a two-way plug. Background technique [0002] Regardless of whether it is newly manufactured hydraulic equipment or hydraulic equipment after overhaul, it is necessary to debug various technical indicators and work performance of the hydraulic system, or debug according to the actual use of various technical parameters. [0003] The debugging of the hydraulic system mainly includes the following aspects. [0004] <1> Various parameters of each action of the hydraulic system, such as force, speed, start point and end point of stroke, time of each action and total time of the entire working cycle, etc., should be adjusted to the technical indicators required by the original design. [0005] <2> Adjust the entire line or the entire hydraulic system to achieve stable and reliable working performance. [0006] <3> During the debugging process, it is necessary to judge the powe...
