Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved angle-adjustable multi-way reversing valve is provided to solve the limitation of the fixed angle of the current multi-way reversing valve, which cannot be freely adjusted according to needs To the designated position, the requirements for the installation position of the multi-way directional valve are relatively high. At the same time, when the delivery port of the multi-way directional valve is loaded and unloaded, it needs to be closed and switched by a manual switch, and the control operation is very cumbersome.

Embodiment 1

[0042] Embodiment 1: When connecting, it is only necessary to disassemble the internal thread assembly sealing cover 25. At this time, the anti-return plate 20 in the internal linkage self-closing frame is turned outward, and there is a non-return plate on the inner wall of the internal installation frame 18. 20 cooperates with the limit closing frame of the integrated structure, the non-return plate 20 is closed, and the outer opening of the external oil delivery conduit 7 is controlled to be closed. The internally threaded oil guide pipe extrudes the external extruding frame 14, and the external extruding frame 14 will synchronously control the inward extrusion of the arc-shaped limit tooth frame 16, and synchronously control the inward turning of the check plate 20, so that the outer oil delivery conduit 7 The opening remains open.

Embodiment 2

[0043] Embodiment 2: as Figure 4 As shown, an arc-shaped sealing closing plate can be fixed on the inner side of the arc-shaped limit tooth frame 16 through an inner connecting rod, so that the internal linkage self-closing frame is not needed, and the arc-shaped discharge can also be located inside the inner material guide tube 3. The openings on both sides of the port 11 are movable and equipped with a sideways flip closing plate matched with an arc-shaped sealing closing plate. When the arc-shaped sealing closing plate is pulled outward, it can automatically close the flow inside the internal material guide pipe 3, so that it can be The on-off circuit of the internal material guide pipe 3 is controlled as required.

[0044] An angle-adjustable multi-way reversing valve of the present invention is provided with a lateral bottom assembly groove 2 with a built-in external oil delivery adjustment device on both sides of the lower surface of the main valve body 1, through which...

Abstract

The invention relates to the technical field of sealing adjusting valves, in particular to an angle-adjustable multi-way reversing valve which comprises a main valve body and is characterized in that lateral bottom assembling grooves with built-in external oil conveying adjusting devices are formed in the two sides of the lower surface of the main valve body; the installation angle of the connecting pipe on the outer side of the multi-way reversing valve can be freely adjusted according to needs through the external oil conveying adjusting device, so that the installation modes and positions of the multi-way reversing valve are more diversified, and the application range is very wide. An internal control mechanism used for controlling the angle is movably assembled in the external oil transportation adjusting device, the internal control mechanism is extruded through threaded assembly, so that the angle of the external oil transportation adjusting device is locked, and an elastic arc-shaped extrusion plate on the inner side arc-shaped surface of an external sealing pipe is matched, so that the stability in the angle adjusting process can be improved; and meanwhile, joint control angle locking can be achieved after threaded fastening, and the structural firmness is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sealing regulating valves, in particular to an angle-adjustable multi-way reversing valve. Background technique [0002] The reversing valve is a directional control valve with more than two flow forms and more than two oil ports. It is a valve that realizes the communication, cut-off and reversing of hydraulic oil flow, as well as pressure unloading and sequential action control. The valve is controlled by the direction of the relative movement of the spool and the valve body. [0003] There are two types of rotary valve and slide valve. According to the number of working positions where the spool stays in the valve body, it is divided into two positions, three positions, etc.; according to the number of oil circuits connected to the valve body, it is divided into two-way, three-way, four-way and six-way, etc.; the way to operate the spool movement There are manual, motorized, electric, hydraulic, ele...
