Description

Technical Field

[0001] This application relates to the field of valves, and more specifically, to a three-position six-way valve. Background Technology

[0002] Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Valves are control components in pipeline fluid transport systems, used to change the cross-sectional area of ​​the passage and the direction of media flow. They have functions such as guiding, stopping, throttling, check valve, diverting, or overflow pressure relief. Existing three-position six-way valves use a sealing ring to seal the valve stem. However, the sealing ring structure in existing three-position six-way valves is simple, resulting in low contact between the sealing ring and the valve stem, which affects the sealing performance between the valve stem and the valve body. Therefore, we propose a new three-position six-way valve. Utility Model Content

Detailed Implementation

[0021] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0022] Please see Figure 1-6 This application provides a three-position six-way valve, including a valve body 10, a valve core 20 inserted inside the valve body 10, a valve stem 30 mounted on the top of the valve core 20, and an assembly plate 40 for press-fitting the valve body 10 inside the valve body 10. A first sealing ring 50 is installed on the inner wall of the assembly plate 40, and a pressure ring 60 is detachably connected to its inner wall. The pressure ring 60 presses the first sealing ring 50, and the first sealing ring 50 is fitted onto the valve stem 30. Specifically, the first sealing ring 50 is fitted onto the valve stem 30. At the same time, when the pressure ring 60 presses the first sealing ring 50 downward, the first sealing ring 50 will deform, so that the inner wall of the first sealing ring 50 is tightly fitted onto the outer wall of the valve stem 30, thereby improving the sealing effect.

[0023] See Figure 6 The inner wall of the assembly plate 40 is provided with a first mounting groove 410. The first sealing ring 50 is inserted into the first mounting groove 410. The pressure ring 60 is threadedly connected to the first mounting groove 410. During installation, the inner wall of the first mounting groove 410 is provided with an internal thread, and the outer wall of the pressure ring 60 is provided with an external thread. The external thread and the internal thread are adapted to each other, so that the pressure ring 60 can be installed into the first mounting groove 410. At the same time, a connecting ring is fixedly installed on the top of the pressure ring 60 to facilitate the rotation of the pressure ring 60. The first sealing ring 50 has an annular groove 510 at its top, and an annular extrusion block 610 is fixedly installed at the bottom of the pressure ring 60. The annular extrusion block 610 is inserted into the annular groove 510 and extrudes the inner wall of the annular groove 510. It should be noted that the pressure ring 60 drives the annular extrusion block 610 to move downward and insert into the annular groove 510, thereby extruding the annular extrusion block 610 from inside the first sealing ring 50, so that the inner wall of the first sealing ring 50 is tightly attached to the valve stem 30, thereby improving the sealing effect.

[0024] See Figure 3 , 46. A second mounting groove 420 is also provided on the inner wall of the assembly plate 40. A bearing 430 is inserted into the second mounting groove 420 and is sleeved on the valve stem 30. In specific installation, the bearing 430 is press-fitted into the second mounting groove 420 and sleeved on the valve stem 30. At the same time, the inner ring of the bearing 430 is placed on the end face of the valve stem 30. Furthermore, several rotating rollers 440 are rotatably connected to the inner wall of the assembly plate 40. The several rotating rollers 440 are all rolled on the top of the valve core 20. It should be noted that in order to reduce the frictional resistance and wear between the assembly plate 40 and the valve core 20, the assembly plate 40 is designed to reduce frictional resistance and wear. A rotating roller 440 is installed on the inner wall of the disc 40. The rotating roller 440 is rolled on the top of the valve core 20 to position the valve core 20 and reduce wear and frictional resistance between it and the valve core 20, so as to facilitate the rotation of the valve core 20. Furthermore, the valve body 10 has an assembly groove 110 and a positioning groove 120. The positioning groove 120 is connected to the assembly groove 110. The valve core 20 is inserted into the assembly groove 110, and the assembly disc 40 is inserted into the positioning groove 120. The assembly groove 110 is adapted to the valve core 20, and the assembly disc 40 is adapted to the positioning groove 120. The valve stem 30 is driven by a motor. Its specific structure is existing technology.

[0025] See Figure 3 The bottom of the positioning groove 120 is provided with a first annular sealing groove 130, and the bottom of the assembly plate 40 is provided with a second annular sealing groove 70. A second sealing ring 80 is provided between the first annular sealing groove 130 and the second annular sealing groove 70. Specifically, after the valve core 20 is pressed into the assembly plate 40, the first annular sealing groove 130 will close with the second annular sealing groove 70 to form an annular hole, which can accommodate the second sealing ring 80 to improve the sealing effect between the assembly plate 40 and the positioning groove 120. The number of second sealing rings 80 can be set according to requirements.

[0026] See Figure 1 , 3 4. A sealing disc 90 is detachably connected to the top of the valve body 10. An annular block 910 is fixedly installed at the bottom of the sealing disc 90. The annular block 910 presses against the top of the assembly disc 40. In a specific configuration, the top of the valve body 10 has several screw holes, and the sealing disc 90 has several through holes. Several screws pass through several through holes and connect to several screw holes to fix the sealing disc 90 to the valve body 10. The valve stem 30 passes through the sealing disc 90. Specifically, a through hole is opened in the center of the sealing disc 90, through which the valve stem 30 can pass. In addition, after the sealing disc 90 is installed, the bottom of the sealing disc 90 contacts the connecting ring at the top of the pressure ring 60, and the annular block 910 positions the assembly disc 40.

[0027] When using this three-position six-way valve: six channels are opened on the side wall of the valve body 10, and three U-shaped holes are opened on the side wall of the valve core 20. The three U-shaped holes switch between the six channels to change the flow path. When assembling the three-position six-way valve of this application, firstly, the valve core 20 is inserted into the assembly groove 110 in the valve body 10, and the U-shaped holes on the valve core 20 correspond to the channels. Then, the bearing 430 is pressed into the second mounting groove 420, and the first sealing ring 50 is inserted into the first mounting groove 410. After that, the assembly plate 40 is pressed into the positioning groove 120 and simultaneously sleeved on the valve stem 30. After the assembly plate 40 is in place, the pressure ring 60 can be connected to the first mounting groove 410, so that the annular extrusion block 610 is inserted into the annular groove 510 to extrude the first sealing ring 50. Finally, the sealing plate 90 is connected to the valve body 10 to complete the assembly.

[0028] It should be noted that the specific model specifications of valve body 10, valve core 20 and valve stem 30 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
