Problems solved by technology
[0002] Hydraulic valve is a commonly used control device in the field of transmission. It has the advantages of small size, simple structure, stepless speed change, and low cost. However, hydraulic valves also have shortcomings in the current transmission technology. The most obvious defect is that only It is suitable for the working conditions of linear transmission. If a hydraulic valve is required to drive a gear, it is very difficult. Therefore, there is no example of a hydraulic valve directly driving a gear in the current technical data and practical applications.

Embodiment Construction
[0022] figure 1 - Figure 4 The marking names are: lower valve body (1), liquid nozzle in the rear chamber (2), mounting screw hole A (3), sealing ring A (4), square guide post (5), liquid nozzle in the front chamber (6), push Rod (7), seal ring B (8), push rod head (9), push rod arc head (10), reset alignment groove (11), connection bottom (12), push rod square hole (13), front Liquid chamber (14), upper valve body (15), front liquid chamber (16), tightening screw hole (17) and mounting screw hole B (18).
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] Such as figure 1 As shown, the double hydraulic valve consists of two lower valve bodies (1) symmetrically arranged on the connecting bottom (12), forming the base of the double hydraulic valve.
[0025] Such as figure 1 As shown, on the center of the opposite surfaces of the upper valve bodies (15) of the two double-connected hydraulic valves, there...

The invention belongs to the field of hydraulic transmission, and particularly discloses a duplex type hydraulic valve. The duplex type hydraulic valve comprises lower valve bodies (1), a rear chamber nozzle (2), an installation screw hole A (3), a sealing ring A (4), a square guide pillar (5), a front chamber nozzle (6), a push rod (7), a sealing ring B (8), a push rod head (9), a push rod arc head (10), a reset calibration groove (11), a connecting bottom (12), a push rod square hole (13), a front liquid chamber (14), an upper valve body (15), a front liquid chamber (16), a fastening screw hole (17) and an installation screw hole B (18), wherein the duplex type hydraulic valve is formed as a duplex structure by connecting two symmetry lower valve bodies (1) through the connecting bottom (12); one half of the upper half part of the head part of the push rod head (9) at the front end of the push rod (7) is cut off, and one half is left and arc-shaped, so that the push rod head (9) can flexible advance and retreat between two helical teeth of a helical gear; and the duplex type hydraulic valve can be widely applied to the working condition that stepping transmission is implemented through helical gears.
Description
technical field [0001] The invention belongs to the field of hydraulic transmission, in particular to a double hydraulic valve. Background technique [0002] Hydraulic valve is a commonly used control device in the field of transmission. It has the advantages of small size, simple structure, stepless speed change, and low cost. However, hydraulic valves also have shortcomings in the current transmission technology. The most obvious defect is that only It is suitable for the working conditions of linear transmission, but it is very difficult to require a hydraulic valve to drive a gear, so there is no example of a hydraulic valve directly driving a gear in the current technical data and practical applications. [0003] The object of the present invention is to solve the above-mentioned deficiencies. Provide the society with a double hydraulic valve that can directly drive the gear movement. Contents of the invention [0004] A double-connected hydraulic valve, including a...
