Description
Technical Field
[0001] The utility model relates to the technical field of ball valves, in particular to a two-way flow ball valve. Background Art
[0002] A two-way flow ball valve is a ball valve that can flow in both directions. The ball opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. It is used for fluid regulation and control.
[0003] When the existing two-way flow ball valve is in use, the medium may flow in either direction, which requires the sealing ring to maintain good sealing performance in both directions. Long-term two-way pressure may accelerate the wear of the sealing ring and reduce the service life of the sealing ring. Therefore, the sealing ring needs to be replaced frequently. Most of the existing two-way flow ball valves are assembled by combining bolts and nuts, which requires repeated tightening of the nuts when replacing the sealing ring, which takes a long time to replace the sealing ring. At the same time, since the bolts and nuts are exposed to the outside world, their surfaces are prone to rust, which further increases the difficulty of replacing the sealing ring, making replacement of the sealing ring more inconvenient.
[0004] Therefore, it is necessary to provide a new two-way flow ball valve to solve the above technical problems. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a two-way flow ball valve with a sealing ring that is more convenient to replace.
[0006] The two-way flow ball valve provided by the utility model comprises a ball valve body, a valve core is arranged inside the ball valve body, a valve stem is fixed to the top of the valve core, a hand wheel is fixed to the top of the valve stem extending out of the ball valve body, and a first sealing ring is arranged inside the ball valve body and on both sides of the valve core.

Preferably, a baffle is provided inside the groove and outside the fixed rod, and the outer side of the baffle is fixedly connected to the inner wall of the groove.
[0009] In order to improve the sealing performance of the connection between the first valve body and the second valve body, the utility model provides a two-way flow ball valve. Preferably, a plug ring is fixed on one side of the second valve body, two second sealing rings are fixed on the plug ring, and the plug ring is inserted into the slot opened in the first valve body.

A two-way flow ball valve includes a ball valve body 1, a valve core 2 is provided inside the ball valve body 1, a valve stem 3 is fixed to the top of the valve core 2, the valve stem 3 extends out of the top of the ball valve body 1 and is fixed to a handwheel 4, and a first sealing ring 5 is provided inside the ball valve body 1 and on both sides of the valve core 2; the ball valve body 1 includes a first valve body 101 and a second valve body 102, one end of the first sealing ring 5 is inserted into the installation groove 103 provided in the second valve body 102, and a circular ring 104 is fixed to the outside of the first valve body 101 and the outside of the second valve body 102, and two first fixing rings 105 are provided on the outside of the circular ring 104, and the two first fixing rings 105 are rotatably connected by a rotating shaft 106. The first fixing ring 10 Two limiting rings 107 are fixed on the inner side, and the limiting rings 107 are inserted into the limiting grooves 108 provided in the circular ring 104. Connecting plates 109 are fixed to the outer sides of the two first fixing rings 105. A U-shaped block 110 is provided on one side of the two connecting plates 109. The U-shaped block 110 is inserted into the fixing grooves 111 provided in the connecting plates 109. A groove 112 is provided on the U-shaped block 110. A first spring 113 is fixed to the bottom wall of the groove 112. A first extrusion plate 114 is fixed to the top of the first spring 113. A fixing rod 115 is fixed to the top of the first extrusion plate 114. The fixing rod 115 extends out of the top of the groove 112 and is inserted into the fixing hole 116 provided in the connecting plate 109.
[0024] Through the above technical solution, the fixing rod 115 in the fixing hole 116 is pressed to make the fixing rod 115 fall off the fixing hole 116, thereby releasing the restriction of the fixing rod 115 on the U-shaped block 110, and then the U-shaped block 110 is separated from the connecting plate 109, and the two first fixing rings 105 are rotated to separate the limiting ring 107 from the limiting groove 108, and then the first valve body 101 can be separated from the second valve body 102, and then the first sealing ring 5 can be replaced, so that the replacement of the first sealing ring 5 is time-saving and labor-saving, the replacement difficulty is relatively small, and the replacement of the first sealing ring 5 is more convenient.
[0025] Reference Figure 5 A baffle 117 is provided inside the groove 112 and outside the fixing rod 115. The outer side of the baffle 117 is fixedly connected to the inner wall of the groove 112. The baffle 117 limits the movement of the first extrusion plate 114 to prevent the first extrusion plate 114 from moving to the outside of the groove 112 due to the elastic action of the first spring 113, so that the first extrusion plate 114 can be used normally in the groove 112.
[0026] Reference Figure 1 and Figure 4A plug ring 118 is fixed on one side of the second valve body 102, and two second sealing rings 119 are fixed on the plug ring 118. The plug ring 118 is inserted into the slot 120 opened in the first valve body 101. When the first valve body 101 and the second valve body 102 are assembled, the plug ring 118 on one side of the second valve body 102 is inserted into the slot 120. The cooperation between the plug ring 118 and the slot 120 can prevent the first valve body 101 and the second valve body 102 from being misaligned. The two second sealing rings 119 on the plug ring 118 make the first valve body 101 and the second valve body 102 more tightly sealed when connected.
[0027] Reference Figure 1 and Figure 6 124 is provided inside the filter ring 123, and a fixing bolt 125 is provided on one side of the mounting ring 122. One end of the fixing bolt 125 passes through the through hole 126 provided in the mounting ring 122 and is screwed into the thread groove 127 provided in the second fixing ring 121. The filter ring 123 passes through the second fixing ring 121 so that the mounting ring 122 contacts the second fixing ring 121. Then, one end of the fixing bolt 125 passes through the through hole 126 and is screwed into the thread groove 127. The mounting ring 122 and the second fixing ring 121 can be fixed together by the fixing bolt 125 and the thread groove 127. Impurities in the flowing medium are filtered through the filter mesh 124 in the filter ring 123 to prevent impurities from aggravating the wear of the first sealing ring 5.
[0028] Reference Figure 6 A movable groove 128 is provided inside the filter ring 123, and a second spring 129 is fixed to the bottom wall of the movable groove 128. A second extrusion plate 130 is fixed to the top of the second spring 129, and a blocking rod 131 is fixed to the top of the second extrusion plate 130. The blocking rod 131 extends out of the movable groove 128 and overlaps with the filter screen 124. Press the blocking rod 131 to make the blocking rod 131 enter the movable groove 128, and then take the filter screen 124 out of the filter ring 123 for replacement, so that the replacement of the filter screen 124 is more convenient.
[0029] The implementation principle of a two-way flow ball valve in an embodiment of the present utility model is: pressing the fixing rod 115 in the fixing hole 116 to make the fixing rod 115 fall off the fixing hole 116, releasing the restriction of the fixing rod 115 on the U-shaped block 110, and then separating the U-shaped block 110 from the connecting plate 109, rotating the two first fixing rings 105 to separate the limiting ring 107 from the limiting groove 108, and then the first valve body 101 can be separated from the second valve body 102, and then the first sealing ring 5 can be replaced, so that the replacement of the first sealing ring 5 is time-saving and labor-saving, the replacement difficulty is relatively small, and the replacement of the first sealing ring 5 is more convenient.
