Further, a fastener is arranged in the valve body, and the fastener is arranged between the threaded rod and the valve body.
Further, a first sealing gasket is arranged between the connecting pipe and the valve body.
Further, set up the spacing groove in the connecting pipe, the spacing groove with the bottom of threaded rod matches the setting.
Further, the bottom end of the threaded rod is coated with a second sealing gasket.
Further, the upper end of the threaded rod is provided with a non-slip mat.
Further, the top of the threaded rod is provided with a switch mark.
The utility model discloses a beneficial effect:
the utility model discloses a rotatory threaded rod for the length that the other end of threaded rod stretched into the connecting pipe changes, and the threaded rod carries out unidirectional rotation and carries out the position simultaneously and shift up or move down, with the inside circulation or the sealing that realize the connecting pipe, when the threaded rod seals with the connecting pipe cooperation, through the sealed pad of second of threaded rod bottom, has avoided sealing the drawback that the corrosion takes place to leak, can reach the valve pressurization and prevent the effect of leaking.
The utility model discloses a rotatory threaded rod for the other end of threaded rod stretches into the connecting rod and accomplishes once fixing a position, continues rotatory threaded rod, makes the other end of threaded rod get into the spacing groove in the connecting tube, thereby accomplishes the secondary location, can reach the locking effect of moving of control valve two-way location.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the valve body 100, the connecting pipe 200, the threaded rod 300, the fastener 400, the first sealing gasket 500, the limiting groove 600, the second sealing gasket 700 and the non-slip mat 800.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1, the control valve described in the present embodiment includes a valve body 100, and a connection pipe 200 connected to the valve body 100, and is characterized in that: one end of the valve body 100 is communicated with the inside of the connecting pipe 200, a threaded rod 300 is arranged in the valve body 100, the threaded rod 300 penetrates through the valve body 100 to be communicated with the connecting pipe 200, the upper end of the threaded rod 300 extends out of the valve body 100, the threaded rod 300 realizes the conversion between a first position and a second position in the valve body 100, and when the first position is reached, the threaded rod 300 is rotated to move downwards to abut against the connecting pipe 200; in the second position, the threaded rod 300 is rotated to move up to the outer wall of the connection tube 200.
The utility model discloses a rotatory threaded rod 300 for the length that the other end of threaded rod 300 stretched into connecting pipe 200 changes, and threaded rod 300 carries out unidirectional rotation and carries out the position simultaneously and shifts up or move down, with the inside circulation or the sealing that realize connecting pipe 200, when threaded rod 300 and connecting pipe 200 cooperation were sealed, through the sealed pad 700 of second of threaded rod 300 bottom, avoided sealing the drawback that the corrosion takes place to leak, can reach the valve pressurization and prevent the effect of leaking.
Specifically, the fastener 400 is arranged in the valve body 100, and the fastener 400 is arranged between the threaded rod 300 and the valve body 100, so that the threaded rod 300 is prevented from easily displacing in the valve body 100, and the use effect is prevented from being influenced.
