DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 -5, a high-low position drain valve device includes a valve body 1, one side of the valve body 1 is connected to a joint 2, the outside of the joint 2 is covered with a sealing ring 3 13, the outer surface of the sealing ring 3 13 is in contact with the inside of the valve body 1, the contact position between the joint 2 and the valve body 1 can be sealed by the sealing ring 3 13 to ensure the stability during connection and use, the sealing ring 29 and the sealing ring 3 13 are O-ring rubber sealing rings for hydraulic and pneumatic use, the used hydraulic and pneumatic O-ring rubber sealing rings have good sealing performance, and can effectively perform dynamic sealing and static sealing.

[0024] A ball 3 is installed inside the valve body 1. A communicating pipeline is provided between the ball 3 and the joint 2. When the ball 3 is rotated, the ball 3 and the inside of the joint 2 can be connected. At this time, the liquid can flow through the inside of the valve body 1. Two sets of sealing gaskets 4 are arranged on both sides of the ball 3. The sealing gaskets 4 are installed inside the valve body 1. The two sides of the ball 3 can be sealed by the sealing gaskets 4 to ensure stability during use.

[0025] A fixing groove 5 is provided inside the sphere 3, and a fixing plate 6 is slidably connected inside the fixing groove 5. Both the fixing groove 5 and the fixing plate 6 are of a straight structure. After the fixing plate 6 enters the fixing groove 5, the rotation of the sphere 3 can be controlled, which is convenient for controlling the rotation of the sphere 3.

[0026] A handle seat 7 is fixedly installed on the upper surface of the fixing plate 6, and the outer surface of the handle seat 7 is sleeved with the interior of the valve body 1. The outer surface of the handle seat 7 is slidably connected with a handle 16, and the handle 16 can be conveniently used to rotate the handle seat 7. The outer surface of the handle seat 7 is threadedly connected with a hexagonal slotted thin nut 17, and a cotter pin 18 is installed inside the hexagonal slotted thin nut 17. The cotter pin 18 can play a good tightening role on the hexagonal slotted thin nut 17, thereby ensuring the stability of the handle 16 when it is fixed.

[0027] The outside of the handle seat 7 is respectively covered with a sealing ring 1 8 and a sealing ring 2 9, which are arranged up and down and in contact with the inside of the valve body 1. The sealing ring 1 8 is an EDM20 sealing ring. The sealing ring 1 8 and the sealing ring 2 9 inside the valve body 1 are provided with stepped installation grooves. The sealing ring 1 8 and the sealing ring 2 9 can perform double sealing on the handle seat 7 to prevent water leakage at the handle seat 7.

[0028] A spring 10 is sleeved on the outside of the handle seat 7, and a positioning plate 11 is slidably installed on the outer surface of the handle seat 7. When the handle seat 7 is rotated, the positioning plate 11 can be controlled to rotate. The outer surface of the positioning plate 11 is rotatably connected to the upper surface of the valve body 1. A positioning groove 14 is provided inside the positioning plate 11, and a positioning pin 15 is connected to the internal thread of the valve body 1. The outer surface of the positioning pin 15 is slidably connected to the inside of the positioning groove 14. The positioning groove 14 is a specific arc shape.

The two ends of the spring 10 can be fixed by the cooperation between the baffle 12 and the positioning plate 11. At this time, the spring 10 will be compressed and generate an upward thrust on the baffle 12, which can further generate an upward thrust on the handle seat 7, and will generate an upward thrust on the sealing ring 1 8 and the sealing ring 2 9, so that the sealing ring 1 8 and the sealing ring 2 9 can be in close contact with the inside of the valve body 1, thereby ensuring the stability of the connection.

[0030] When the interior of the control valve body 1 is connected, the control handle 16 rotates, the handle 16 can drive the handle seat 7 to rotate, and the handle seat 7 will drive the positioning plate 11 to rotate. The rotation angle of the positioning plate 11 can be controlled by the cooperation of the positioning groove 14 and the positioning pin 15, and the rotation angle of the handle seat 7 can be further controlled, and the opening and closing angle of the ball 3 can be limited. The spring 10 can continuously generate an upward thrust on the baffle 12 under the cooperation of the positioning plate 11 and the baffle 12, and can control the sealing ring 1 8 and the sealing ring 2 9 to be in close contact with the inner wall of the valve body 1, thereby ensuring the sealing of the connection position of the handle seat 7.
