[0002] A hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of a pressure regulating valve. It is usually used in combination with an electromagnetic pressure regulating valve and can be used to remotely control the on / off of the oil, gas, and water pipeline systems of a hydropower station. It is often used for clamping, controlling, lubricating, and other oil circuits. There are direct-acting and pilot-operated types, and the pilot-operated type is more commonly used.

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0020] Example

[0021] like Figure 1-3 As shown, a new type of hydraulic valve structure includes a valve body 5, an end cover 3 arranged on the valve body 5, a first valve port 1 and a second valve port 2 respectively arranged on both sides of the valve body 5, a control plate 9 movably arranged in the valve body 5, the valve body 5 is provided with a first mounting portion 4, and the first mounting portion 4 is provided with an oil inlet 7; wherein, a push cylinder 15 is arranged in the valve body 5, a push rod 16 is movably arranged in the push cylinder 15, and the push rod 16 is connected to the control plate 9.

[0022] Specifically, the first valve port 1 is connected to the second valve port 2, and the control plate 9 can cut off the connecting space between the first valve port 1 and the second valve port 2, thereby reducing or even cutting off the liquid flow from the first valve port 1 to the second valve port 2. By arranging a push cylinder 15 in the valve body 5, the control plate 9 is controlled by driving the push rod 16 through the push cylinder 15, thereby avoiding directly controlling the control plate 9 through hydraulic oil, thereby enhancing the stability of the hydraulic valve.

[0023] Preferably, the push cylinder 15 is mounted on the first mounting portion 4 .

[0024] The applicant needs to emphasize that the structure of the oil circuit of the oil inlet 7 is regarded as a mature prior art, which at least includes a hydraulic station and corresponding connecting pipes and connecting valve bodies, and its specific structure will not be elaborated too much here.

[0025] Furthermore, a connecting rod 11 is arranged between the push rod 16 and the control plate 9, one end of the connecting rod 11 is hinged to the control plate 9, and the other end of the connecting rod 11 is hinged to the push rod 16. The push rod 16 at least partially contacts the end cover 3. When the push rod 16 is in an inclined state through the connecting rod 11, the pressure received by the control plate 9 can be transmitted to the end cover 3 through the connecting rod 11. When the connecting rod 11 is in a vertical state, the connecting rod 11 is at a dead point, and the pressure received by the control plate 9 is the largest (the control plate 9 is in a state of cutting off the connecting space between the first valve port 1 and the second valve port 2). The connecting rod 11 at the dead point can transfer all the pressure received by the control plate 9 to the end cover 3, and the mechanical structure is used to replace the hydraulic structure to withstand the pressure, thereby enhancing the stability of the hydraulic valve.

[0026] Furthermore, a slider 10 is provided at one end of the push rod 16 away from the push cylinder 15. The slider 10 is movably provided on the end cover 3. The push rod 16 is hinged to the connecting rod 11 through the slider 10. The slider 10 is movably provided on the end cover 3. The connection between the slider 10 and the push rod 16 can prevent the push rod 16 from receiving a large vertical force. The vertical force can be directly transmitted from the connecting rod to the slider 10 and then transmitted to the end cover 3 through the slider 10.

[0027] Further, the first mounting portion 4 is provided with a first positioning column 8, the control board 9 is provided with a positioning hole adapted to the first positioning column 8, the end cover 3 is provided with a second positioning column 17, and the control board 9 is provided with a positioning groove adapted to the second positioning column 17. The first positioning column 8 and the second positioning column 17 are used to guide the control board 9 to ensure that the control board 9 moves in only one direction.

[0028] Furthermore, a guide belt 13 is provided between the push rod 16 and the push cylinder 15 ; the guide belt 13 is used to guide the push rod 16 .

[0029] The end of the push rod 16 is provided with a second connecting portion 12, and the second connecting portion 12 is connected to the slider 10. By providing the second connecting portion 12, when the slider 10 is damaged, only the second connecting portion 12 and the slider 10 can be replaced, avoiding the need to replace the push rod 16 and the push cylinder 15, thereby reducing maintenance costs.

[0030] Furthermore, a fastener 6 is provided between the end cover 3 and the valve body 5, and the end cover 3 and the valve body 5 are connected via the fastener 6. The fastener 6 is preferably a screw.

[0031] The above-mentioned technical features can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
