Examples

With reference to fig. 1-5, a ball valve with a backwashing filter comprises a main pipeline 1 and a branch pipeline 11, wherein the main pipeline 1 is provided with a ball valve and a switch 12, the end of the main pipeline 1 is provided with a connecting nut 13, and the ball valve is connected with other pipelines through the connecting nut 13. Threaded connection has sleeve valve joint 2 on the branch pipeline 11, and sleeve valve joint 2 other end threaded connection has movable nut 3, and sleeve valve joint 2 all is equipped with the screw thread through 3 joint elbow fitting 4 of movable nut, sleeve valve joint 2 both ends, and the middle part is equipped with the step of hex-horn shape. The threads at the two ends of the sleeve valve joint 2 are used for connecting the branch pipeline 11 and the elbow joint 4, and the hexagonal step facilitates a wrench to screw the sleeve valve joint 2, so that the assembly and disassembly are convenient. The end part of the elbow joint 4 is provided with a ring bulge and a plurality of layers of sealing structures, and the sealing structures comprise a plurality of layers of ring grooves arranged at the end part of the elbow joint 4 and sealing rings in the ring grooves. The sealing ring is positioned in the annular groove, and fills a gap between the elbow joint 4 and the branch pipeline 11, so that the sealing performance is improved. The movable nut 3 is provided with an eccentric round hole 31 matched with the annular protrusion, and the eccentric round hole 31 is eccentric with the annular protrusion. The movable nut 3 is provided with an internal thread which is matched with the sleeve valve joint 2. The internal thread of the movable nut 3 is used for meshing connection with the external thread of the sleeve valve connector 2. The main pipeline 1 and the branch pipeline 11 are Y-shaped, the main pipeline 1 is used for medium circulation in normal operation, the branch pipeline 11 is not started in normal operation, and the main pipeline and the branch pipeline are started only in backwashing. The switch 12 is a rotating handle for controlling the rotation of the spool to control the ball valve. The branch pipeline 11 is connected with the elbow joint 4 through the sleeve valve joint 2 and the movable screw cap 3, and the elbow joint 4 is connected with the back washing filter device and is provided with a switch 12. When the elbow joint 4 is not mounted on the branch pipeline 11, the annular protrusion of the elbow joint 4 can pass through the eccentric circular hole 31 of the movable nut 3, the thread of the movable nut 3 is meshed with the thread on the branch pipeline 11 after the elbow joint 4 is mounted on the branch pipeline 11, and the elbow joint 4 and the branch pipeline 11 are concentric. At this time, the thin-wall side of the eccentric circular hole 31 is buckled with the annular protrusion of the elbow joint 4, so that the elbow joint 4 is limited. The thin-wall radius of the eccentric circular hole 31 is smaller than the radius of the annular protrusion, and the diameter of the eccentric circular hole 31 is larger than the diameter of the annular protrusion. The reason why the radius of the thin wall of the eccentric circular hole 31 is smaller than the radius of the annular protrusion is that the movable nut 3 can buckle the annular protrusion of the elbow joint 4 after being connected to the branch pipeline 11 in a threaded manner to limit the elbow joint 4. The reason why the diameter of the eccentric circular hole 31 is larger than that of the annular protrusion is that the movable nut 3 needs to be directly sleeved on the elbow joint 4 from the joint, and the other end of the elbow joint 4 is an elbow pipe and is not easy to be sleeved. The elbow joint 4 is connected with a backwashing filter. The filter is an indispensable filtering device for the pipeline system for conveying the medium, and the filter is usually installed at the inlet end of a pressure reducing valve, a pressure relief valve, a constant water level valve or other equipment and is used for removing impurities in the medium so as to protect the normal use of the valve and the equipment. The filter has the characteristics of advanced structure, small resistance, convenient pollution discharge and the like. The structural strength of the elbow joint 4 of the integrally formed structure is greatly enhanced.

The installation process comprises the following steps:

screwing the sleeve valve joint 2 into the branch pipeline 11 pipeline, then sleeving the movable screw cap 3 into the elbow joint 4, sleeving the movable screw cap 3 from one end of the elbow joint 4 close to the branch pipeline 11 pipeline, enabling the elbow joint 4 to penetrate through an eccentric hole of the movable screw cap 3, screwing the movable screw cap 3 onto the sleeve valve joint 2, and then installing the backwashing filter at the other end of the elbow joint 4. The disassembly is completed only by unscrewing the movable nut 3.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
