Description

Technical Field

[0001] This invention relates to the field of valve equipment technology, and in particular to a structure for an internally threaded ball valve. Background Technology

[0002] Currently, valves are used to control the flow rate in pipelines. The valves currently in use are usually gate valves. Gate valves require a lot of rotation to open and close during use, which makes the sealing surface prone to wear, reducing the service life of the valve and resulting in poor sealing performance.

[0003] In the existing technology, internal threaded ball valves are used to open and close pipelines. During the opening and closing process, the ball valve reduces wear on the sealing surface, making the valve last longer. In addition, the opening and closing stroke angle is small, allowing for rapid opening and closing.

[0004] However, with existing technology, three ball valves are required to control three different pipelines separately when performing diversion, which makes the operation of opening and closing steps cumbersome, and it is not possible to control three pipelines with a single ball valve. Summary of the Invention

[0005] The purpose of this invention is to provide an internal thread ball valve structure, which aims to solve the technical problem in the prior art that three ball valves are required to control three different pipelines separately when performing flow diversion, resulting in cumbersome operation steps and the inability to control three pipelines with a single ball valve.

[0006] To achieve the above objectives, the present invention employs an internal thread ball valve structure, comprising a valve stem and a multi-control mechanism. The multi-control mechanism includes a valve body, a ball core, external connecting pipes, baffles, and connecting posts. The ball core is disposed inside the valve body. One end of the valve stem passes through the valve body and is engaged with the ball core. There are three external connecting pipes, each communicating with the valve body and located on the outer wall of the valve body. There are six baffles, each disposed inside the valve body. There are six connecting posts, each disposed inside the valve body.

[0007] The valve body has fifteen channels, namely, the first channel, the second channel, the third channel, the fourth channel, the fifth channel, the sixth channel, the seventh channel, the eighth channel, the ninth channel, the tenth channel, the eleventh channel, the twelfth channel, the thirteenth channel, the fourteenth channel, and the fifteenth channel. Three external connecting pipes are respectively connected to the corresponding first channel, the sixth channel, and the eleventh channel. Six connecting posts are respectively disposed inside the corresponding fourth channel, the fifth channel, the seventh channel, the tenth channel, the thirteenth channel, and the fifteenth channel. Six baffles are respectively disposed inside the corresponding second channel, the third channel, the eighth channel, the ninth channel, the twelfth channel, and the fourteenth channel.

[0008] The valve body further comprises a first connecting channel, a second connecting channel, and a third connecting channel. The first connecting channel is connected to the second channel, the third channel, the fourth channel, the fifth channel, and the sixth channel, respectively. The second connecting channel is connected to the seventh channel, the eighth channel, the ninth channel, the tenth channel, and the eleventh channel, respectively. The third connecting channel is connected to the twelfth channel, the thirteenth channel, the fourteenth channel, the fifteenth channel, and the first channel, respectively.

[0009] The ball core has a first flow channel, a second flow channel, and a third flow channel, and the first flow channel, the second flow channel, and the third flow channel are connected.

[0010] The internal thread ball valve structure also includes an auxiliary mechanism, which is located at the upper end of the valve body.

[0011] The auxiliary mechanism includes a rotating ring, a rotating rod, and a retaining ring. The rotating ring is sleeved on the outer wall of the valve stem. The retaining ring is threaded to the valve stem and sleeved on the outer wall of the valve stem, with the retaining ring located above the rotating ring. There are multiple rotating rods, each of which is fixedly connected to the rotating ring and located on the outer wall of the rotating ring.

[0012] The auxiliary mechanism further includes three connecting flanges, each of which is fixedly connected to the corresponding outer pipe and is fitted onto the outer wall of the corresponding outer pipe.

[0013] The present invention discloses an internal threaded ball valve structure. By connecting each of the external connecting pipes to the corresponding pipes, rotating the valve stem allows different channels in the valve body to be connected. The baffle and the connecting column are disposed inside the valve body to control the flow of the valve body. The ball core is adapted to the valve body to achieve the purpose of connecting different channels. The above structure can effectively control three different pipes through one valve, making valve adjustment more convenient and faster. Attached Figure Description

Detailed Implementation

[0020] The first embodiment of this application is as follows:

[0021] Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the structure of the first embodiment. Figure 2 This is a front view of the first embodiment. Figure 3 The first embodiment is shown in the internal structural cross-sectional view. The present invention provides an internal threaded ball valve structure, including a valve stem 101 and a multi-control mechanism. The multi-control mechanism includes a valve body 102, a ball core 103, an external connecting pipe 104, a baffle 105, and a connecting post 106. The valve body 102 has fifteen channels, namely, a first channel 107, a second channel 108, a third channel 109, a fourth channel 110, a fifth channel 111, a sixth channel 112, a seventh channel 113, an eighth channel 114, a ninth channel 115, a tenth channel 116, an eleventh channel 117, a twelfth channel 118, a thirteenth channel 119, a fourteenth channel 120, and a fifteenth channel 121. The valve body 102 also has a first connecting channel 122, a second connecting channel 123, and a third connecting channel 124. The ball core 103 has a first flow channel 125, a second flow channel 126, and a third flow channel 127.

[0022] In this specific embodiment, by rotating the valve stem 101, the ball core 103 is rotated, and then different channels, connecting channels and flow channels are used to cooperate, so that the fluid in the valve body 102 can be controlled in different ways.

[0023] The valve body 102 is equipped with a ball core 103. One end of the valve stem 101 passes through the valve body 102 and is engaged with the ball core 103. There are three external pipes 104, each of which is connected to the valve body 102 and located on the outer wall of the valve body 102. There are six baffles 105, each of which is located inside the valve body 102. There are six connecting posts 106, each of which is located inside the valve body 102. Each external pipe 104 is connected to a corresponding pipe. Rotating the valve stem 101 allows different channels in the valve body 102 to be connected. The baffles 105 and the connecting posts 106 are located inside the valve body 102 to control the flow of the valve body 102. The ball core 103 is adapted to the valve body 102 to achieve the purpose of connecting different channels.

[0024] Secondly, the three external connecting pipes 104 are respectively connected to the corresponding first channel 107, the sixth channel 112 and the eleventh channel 117. The six connecting pillars 106 are respectively disposed inside the corresponding fourth channel 110, the fifth channel 111, the seventh channel 113, the tenth channel 116, the thirteenth channel 119 and the fifteenth channel 121. The six baffles 105 are respectively disposed inside the corresponding second channel 108, the third channel 109, the eighth channel 114, the ninth channel 115, the twelfth channel 118 and the fourteenth channel 120. Through the first channel 107 to the fifteenth channel 121, different fluid flow directions can be formed inside the valve body 102, thereby achieving control of the three different pipes.

[0025] Meanwhile, the first connecting channel 122 is connected to the second channel 108, the third channel 109, the fourth channel 110, the fifth channel 111, and the sixth channel 112, respectively. The second connecting channel 123 is connected to the seventh channel 113, the eighth channel 114, the ninth channel 115, the tenth channel 116, and the eleventh channel 117, respectively. The third connecting channel 124 is connected to the twelfth channel 118, the thirteenth channel 119, the fourteenth channel 120, the fifteenth channel 121, and the first channel 107, respectively. The first connecting channel 122, the second connecting channel 123, and the third connecting channel 124 are adapted to the connecting post 106 to facilitate fluid control.

[0026] In addition, the spherical core 103 has a first flow channel 125, a second flow channel 126 and a third flow channel 127, and the first flow channel 125, the second flow channel 126 and the third flow channel 127 are connected, and the first flow channel 125, the second flow channel 126 and the third flow channel 127 are used to divide the fluid.

[0027] When using an internal thread ball valve structure according to this embodiment, rotating the valve stem 101 rotates the ball core 103, thereby adjusting the flow direction of the fluid;

[0028] When the first flow channel 125, the second flow channel 126 and the third flow channel 127 are connected to the corresponding first channel 107, the sixth channel 112 and the eleventh channel 117 respectively, the valve body 102 is in the fully open state.

[0029] When the valve stem 101 is rotated, the first flow channel 125, the second flow channel 126, and the third flow channel 127 are connected to the corresponding second channel 108, the seventh channel 113, and the twelfth channel 118, respectively. Due to the connection of the first connecting channel 122, the second connecting channel 123, and the third connecting channel 124, fluid can flow between the first channel 107 and the sixth channel 112.

[0030] When the valve stem 101 is rotated again, the first flow channel 125, the second flow channel 126, and the third flow channel 127 are connected to the corresponding third channel 109, the eighth channel 114, and the thirteenth channel 119, respectively. Due to the connection of the first connecting channel 122, the second connecting channel 123, and the third connecting channel 124, fluid can flow between the sixth channel 112 and the eleventh channel 117.

[0031] When the valve stem 101 is rotated again, the first flow channel 125, the second flow channel 126, and the third flow channel 127 are connected to the corresponding fourth channel 110, the ninth channel 115, and the fourteenth channel 120, respectively. Due to the connection of the first connecting channel 122, the second connecting channel 123, and the third connecting channel 124, fluid can flow between the first channel 107 and the eleventh channel 117.

[0032] When the valve stem 101 is rotated again, and the first flow channel 125, the second flow channel 126 and the third flow channel 127 are connected to the corresponding fifth channel 111, the tenth channel 116 and the fifteenth channel 121 respectively, the valve body 102 is in a fully closed state due to the blockage of the connecting column 106.

[0036] The rotating ring 201 is sleeved on the outer wall of the valve stem 101. The retaining ring 203 is threadedly connected to the valve stem 101 and sleeved on the outer wall of the valve stem 101, with the retaining ring 203 located above the rotating ring 201. There are multiple rotating rods 202, each of which is fixedly connected to the rotating ring 201 and located on the outer wall of the rotating ring 201. The arrangement of the rotating ring 201 and the rotating rods 202 facilitates the control of the rotation of the valve stem 101. At the same time, the retaining ring 203 holds the rotating ring 201 to prevent it from falling off.

[0037] Secondly, there are three connecting flanges 204, each of which is fixedly connected to the corresponding outer pipe 104 and is respectively sleeved on the outer wall of the corresponding outer pipe 104. The connecting flanges 204 facilitate the connection of the outer pipe 104.

[0038] When using the internal thread ball valve structure of this embodiment, the arrangement of the rotating ring 201 and the rotating rod 202 facilitates the control of the rotation of the valve rod 101. At the same time, the retaining ring 203 holds the rotating ring 201 to prevent it from falling off. The connecting flange 204 facilitates the connection of the external pipe 104.
