A mounting groove is provided below the inner end of the valve seat. A second spring is provided in the mounting groove. The upper end of the second spring is connected to the valve seat, and the lower end is connected to the bottom end face of the mounting groove. The lower edge of the valve plate is a double-arc convex surface, and a double-arc groove is provided on the upper end of the valve seat. The double-arc convex surface is used in conjunction with the double-arc groove. When closed, the double-arc convex surface is sealingly connected to the double-arc groove. This application sets up a double sealing structure, one is to use the guide sealing sleeve and the side end face of the valve plate for sealing, the other is to use the double arc convex surface and the double arc groove for sealing, and a spring is set at the lower end of the valve seat. The elastic force of the spring is used to further enhance the sealing effect, and the sealing effect is relatively good.

DETAILED DESCRIPTION
[0020] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.
[0021] Figures 1 to 3 It is the best embodiment of the utility model, and the following Figures 1 to 3 The utility model is further described.
[0022] A double-seal hydraulic valve comprises a valve body 1, a blocking component and a control component, wherein the blocking component is arranged inside the valve body 1 and the opening and closing of the valve body 1 is controlled by the blocking component, the control component is installed on the surface of the valve body 1, and the control component is connected to the blocking component and the opening and closing of the blocking component can be controlled by the control component, and the blocking component comprises two sealing parts, and the two sealing parts can operate alternately.
[0023] The blocking component includes a blocking plate 2, a conducting pipe 3 and an actuating block 4. The blocking plate 2 is fixedly installed in the valve body 1, and the blocking plate 2 separates the valve body 1. The conducting pipe 3 is fixedly installed in the middle of the blocking plate 2, and both ends of the conducting pipe 3 are connected to the valve body 1. The actuating block 4 is arranged in the conducting pipe 3, and the actuating block 4 can slide along the axial direction of the conducting pipe 3 under the action of the control component. The two sealing parts are respectively installed at both ends of the conducting pipe 3. In this way, the conducting pipe 3 can be closed by only moving the actuating block 4 close to the sealing part, thereby completing the closing of the valve.
[0024] The two sealing parts include a sealing ring 5 and a sealing plate 6, which are fixedly mounted at both ends of the conducting tube 3, respectively. A water hole 7 is provided on the surface of the sealing plate 6, and a water flow channel exists between the action block 4 and the inner wall of the conducting tube 3. At the same time, the action block 4 can block the inner hole of the sealing ring 5 and the water hole 7. In this way, the conducting tube 3 can be shut off by only blocking the inner hole of the sealing ring 5 and the water hole 7 by the action block 4.
[0025] There are several water holes 7, which are evenly distributed around the circumference. This can effectively increase the water flow rate, and the multiple water holes 7 can also form a filter to intercept larger impurities in the water, thereby protecting the valve.
[0026] The blocking component also includes a sealing ring 8. There are two sealing rings 8, both fixedly mounted on the surface of the action block 4, and the two sealing rings 8 are respectively close to the two ends of the conducting tube 3. In this way, the action block 4 can further facilitate closing the inner hole of the sealing ring 5 and the water hole 7.
[0027] The control component includes a control screw 9 and a handwheel 10. A mounting tube 11 is provided on the surface of the valve body 1. A fixing block 12 is fixedly installed in the middle of the mounting tube 11. The control screw 9 is threadedly installed in the middle of the fixing block 12, and the bottom end of the control screw 9 extends into the conducting tube 3 and is fixedly connected to the action block 4. The handwheel 10 is fixedly installed on the top of the control screw 9. In this way, the action block 4 can be driven to move by rotating the handwheel 10 to drive the control screw 9 to rotate. The action block 4 will approach the sealing ring 5 or the sealing plate 6 until the action block 4 blocks the inner hole of the sealing ring 5 or the water hole 7, and the conducting tube 3 can be blocked.
[0028] The surface of the valve body 1 is provided with an inlet pipe 13 and an outlet pipe 14, and flanges 15 are installed at the ends of the inlet pipe 13 and the outlet pipe 14 away from the valve body 1. At the same time, the inlet pipe 13 is connected with the water hole 7, so that impurities in the incoming water can be easily intercepted.
[0029] Therefore, the complete usage process is to first connect the water inlet pipe 13 and the water outlet pipe 14 to the water inlet end and the water outlet end of the pipeline to be controlled, and then turn the hand wheel 10 to drive the control screw 9 to rotate, so as to drive the action block 4 to move. The action block 4 will approach the sealing ring 5 or the sealing plate 6 until the action block 4 blocks the inner hole of the sealing ring 5 or the water hole 7, so as to block the conducting pipe 3, thereby achieving the function of closing the valve. Among them, the action block 4 moves in two directions, namely, toward the sealing ring 5 and toward the sealing plate 6, and both directions can form a seal when moving to the end. In this way, the two seals are operated alternately, and when one seal is in progress, the other seal will be idle. In this way, when one seal fails due to wear, after switching to the other seal, a stable sealing effect can still be maintained, and seamless switching can be achieved. In general, the function is more complete.
[0030] At the same time, during use, rotating the control screw 9 in any direction can drive the action block 4 to block the conducting tube 3. In this way, when the entire valve needs to be closed in time, the hand wheel 10 can be directly turned without determining the direction of rotation. Relatively speaking, it can save the user's time in determining the closing direction, has a certain anti-fool function, and is more convenient to use.
[0031] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
