in the process that the connecting pipe sealing body 5 rotates from the sealing body sealing position to the axial overturning limiting position, the communication state between the first end of the control pipe body 1 and the second end of the control pipe body 1 is gradually increased; after the connecting pipe sealing body 5 is rotated from the sealing body sealing position to the axial overturning limiting position direction through an overturning driving force, the overturning reciprocating control mechanism can generate a corresponding resetting acting force after overturning, and after the overturning driving force for driving the connecting pipe sealing body 5 to move is cancelled, the resetting acting force after overturning is utilized to enable the connecting pipe sealing body 5 to automatically reset to the sealing body sealing position in the control pipe body 1.
Specifically, the control pipe body 1 is tubular, the fluid medium can be allowed to pass through the control pipe body 1, so as to realize the transportation of the fluid medium, and the fluid medium passing through the control pipe body 1 can be a plurality of different fluid media, wherein the plurality of fluid media means that more than one fluid medium exists in the control pipe body 1 or the same fluid medium has different process parameters, and the process parameters generally can include temperature, pressure, concentration, and the like, for example, the fluid to pass through the control pipe body 1 includes water and sulfuric acid at the same time, or the fluid to pass through the control pipe body 1 includes cold water and hot water at the same time, the specific situations of the plurality of fluid media can be selected according to actual needs, of course, the fluid medium passing through the control pipe body 1 can also be a single type of fluid, and the specific situations can be selected according to actual needs, and are known to those skilled in the art, and will not be described in detail herein.
Generally, the first end of the control tube body 1 is aligned with the second end of the control tube body 2 and coincides with the axis of the control tube body 1. In order to adjust and control the state of the fluid medium passing through the control pipe body 1, a connecting pipe sealing body 5 is arranged in the control pipe body 1, and the connecting pipe sealing body 5 is connected with the overturning reciprocating control mechanism.
During the concrete implementation, the connecting pipe sealing body 5 is in the control pipe body 1 and can move in the control pipe body 1, and the movement of the connecting pipe sealing body 5 in the control pipe body 1 specifically means that the connecting pipe sealing body 5 can overturn or rotate in the control pipe body 1. When the connecting pipe sealing body 5 is located at the sealing body sealing position, the fluid medium can be blocked from flowing in the control pipe body 1 through the connecting pipe sealing body 5, namely when the connecting pipe sealing body 5 is located at the sealing body sealing position, the fluid medium cannot pass through the control pipe body 1; and when the connecting pipe sealing body 5 is positioned at the axial overturning limiting position, the first end of the control pipe body 1 and the second end of the control pipe body 1 can be in the maximum communication state, and at the moment, the flow of the fluid medium in the control pipe body 1 is maximum. Generally, the seal body sealing position is an initial position of the connecting tube seal 5 in the control tube body 1.
In the embodiment of the present invention, when the connecting pipe sealing body 5 rotates from the sealing body position to the axial overturn limiting position, the communication state between the first end of the control pipe body 1 and the second end of the control pipe body 1 gradually increases, and when the connecting pipe sealing body 5 is located at the axial overturn limiting position, the first end of the control pipe body 1 and the second end of the control pipe body 1 can be in the maximum communication state. When the connecting pipe sealing body 5 rotates on the control pipe body 1, a turning driving force is needed, the connecting pipe sealing body 5 is driven to rotate through the turning driving force, and the position of the connecting pipe sealing body 5 in the control pipe body 1 can be controlled according to the size of the turning driving force.
During specific implementation, as long as the connecting pipe sealing body 5 rotates from the sealing body sealing position to the axial overturning limiting position, the overturning reciprocating control mechanism can generate corresponding resetting acting force after overturning, so that after the overturning driving force for driving the connecting pipe sealing body 5 to move is cancelled, the resetting acting force after overturning is utilized to enable the connecting pipe sealing body 5 to automatically reset to the sealing body sealing position in the control pipe body 1. When the pipe is used or operated, the fluid medium can be enabled to pass through the control pipe body 1 under the action of the provided overturning driving force, and the circulation of the fluid medium is ensured; and after the overturning driving force disappears or is cancelled, the control tube body 1 can be immediately and automatically closed, and no external action is required to be exerted when the control tube body 1 is closed, so that the use safety and reliability are improved.
Further, a corresponding overturning driving force is provided through the flowing of the fluid medium flowing from the first end of the control pipe body 1 to the second end of the control pipe body 1 in the control pipe body 1, or the corresponding overturning driving force is provided through the matching of an overturning reciprocating control mechanism and the connecting pipe sealing body 5;

Specifically, the overturning driving force for driving the connecting pipe sealing body 5 to move may be generated when the fluid medium circulates and contacts the connecting pipe sealing body 5, or may be formed by an acting force loaded to the overturning reciprocating control mechanism, and a generation form of the specific overturning driving force may be selected according to actual needs, which is not described herein again. When the fluid medium flows to contact with the connecting pipe sealing body 5 to generate the overturning driving force, the flowing direction of the fluid medium in the control pipe body 1 is the direction flowing to the second end of the control pipe body 1 along the first end of the control pipe body 1, namely the flowing direction is consistent with the moving direction of the connecting pipe sealing body 5 moving from the sealing body sealing position to the axial overturning limiting position in the control pipe body 1. And when the direction of flow of fluid medium in control body 1 was for following the first end of the second end flow direction of control body 1, because the direction of flow of fluid medium is unanimous with the effect direction of the back reset action power of upset, can reset and keep the connecting pipe sealing body 5 to the sealing body sealing position, can directly turn off the motion of fluid medium in control body 1 this moment, until there is the upset drive power of loading upset reciprocating control mechanism, can make connecting pipe sealing body 5 to the spacing position direction motion of axial upset, even get control body 1 and be in the open mode.
In the embodiment of the invention, the first end of the control pipe body 1 can be also provided with the pipe body connecting pipe 3, and the pipe body connecting pipe 3 can be conveniently connected and matched with an external pipeline and the like. When the pipe connecting pipe 3 is assembled at the first end of the control pipe body 1, the pipe connecting pipe 3 and the control pipe body 1 are coaxially distributed, and the pipe connecting pipe 3 is communicated with the control pipe body 1. Specifically, the connecting tube sealing body 5 is adjacent to the tube connecting tube 3 in the control tube body 1, and when the connecting tube sealing body 5 is located at the sealing body sealing position, the connecting state between the tube connecting tube 3 and the second end of the control tube body 1 can be blocked by the connecting tube sealing body 5.
