[0026] A ceramic silo top switching valve, such as Figure 1 As shown, it includes:

[0027] The valve body 10 has connecting pipes 11 fixedly installed on both sides for connecting pipelines. Each connecting pipe 11 has a flange 12 fixedly installed at its end. A push cylinder is fixedly installed on the top of the valve body 10. A valve core is provided inside the valve body 10. The output shaft of the push cylinder is fixedly connected to the valve core. The inside of the valve body 10 is provided with a wear-resistant ceramic coating to ensure wear resistance and corrosion resistance.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the connector is provided at the end of the pipe 11 to lock the pipe 11 to the pipeline. The connector includes a limiting end plate 20 and an installation channel 23. Two limiting end plates 20 are provided on one side of the baffle 12. The two limiting end plates 20 together form a closed ring. Several installation channels 23 for installation are opened at the end of the limiting end plate 20. The limiting end plate 20 is a semi-circular body. Several installation channels 23 are opened at equal intervals at the end of the limiting end plate 20. The installation channels 23 penetrate the limiting end plate 20. The baffle 12 is a ring. The inner diameter of the limiting end plate 20 is smaller than the outer diameter of the baffle 12. The inner circumferential surface of the limiting end plate 20 is in contact with the outer wall of the pipe 11.

[0029] In this design, two detachable limiting end plates 20 form a ring. When connecting the pipe 11 to the pipeline, the ring formed by the two limiting end plates 20 can rotate on one side of the flange 12, which facilitates the adjustment of the alignment between the installation channel 23 and the flange hole of the pipeline. This breaks the limitation of the flange mounting hole when the pipe 11 and the pipeline are connected through the flange, making the installation more convenient and easier. It also keeps the valve body 10 in a vertical installation position, reducing the probability of uneven wear of the valve core and push cylinder output shaft caused by the valve body 10 tilting due to the flange installation limitation.

[0030] As Figure 3 , Figure 4 and Figure 5 shown, the connecting piece further comprises a lock block 21, the end of the limiting end plate 20 is detachably mounted with the lock block 21, the lock block 21 can lock and close the two limiting end plates 20, the connecting piece further comprises a slot 22, the two limiting end plates 20 are both provided with the same slot 22, the lock block 21 can be inserted into the slot 22, the lock block 21 comprises an arc-shaped rod, one integral round block is arranged at each end of the arc-shaped rod, the two round blocks and the arc-shaped rod jointly form the lock block 21, the depth of the slot 22 is equal to the thickness of the lock block 21, the depth of the slot 22 is less than the thickness of the limiting end plate 20, one slot 22 is arranged at each end of the limiting end plate 20, and the slots 22 in the wall surfaces of the two limiting end plates 20 jointly form a notch suitable for the lock block 21;

[0031] In the scheme, the two limiting end plates 20 are relatively independent when being installed on the outer wall of the connecting pipe 11, in order to make the two limiting end plates 20 form a stable circular ring structure, after the limiting end plate 20 is clamped on the outer wall of the connecting pipe 11, the two lock blocks 21 are inserted into the corresponding slots 22, and then the limiting end plate 20 is locked with the flange of the pipeline through a screw, the lock block 21 abuts against one side end of the blocking edge 12, and the two limiting end plates 20 form a stable circular ring through the two lock blocks 21, thereby guaranteeing the strength of the connecting pipe 11 after being installed with the flange of the pipeline, and meanwhile, the convenience of dismounting the limiting end plate 20 is not lost.

[0032] The working principle of the utility model is as follows: after the limiting end plate 20 is clamped on the outer wall of the connecting pipe 11, the two lock blocks 21 are inserted into the corresponding slots 22, the installation channel 23 is aligned with the flange hole of the pipeline by rotating the limiting end plate 20, the bolt is passed through the installation channel 23 and the flange hole of the pipeline, the limiting end plate and the flange are locked through a nut, the lock block 21 abuts against one side end of the blocking edge 12 after the limiting end plate 20 is locked with the flange of the pipeline through a screw, the two limiting end plates 20 form a stable circular ring through the two lock blocks 21, the screw rod provides a radial pulling force for the limiting end plate 20, so that the blocking edge 12 is kept closely combined with the end of the pipeline, the connection between the connecting pipe 11 and the pipeline is realized, and in order to guarantee the sealing performance, the end of the blocking edge 12 is provided with a gasket to improve the sealing performance.

[0033] The scheme is suitable for fly ash conveying, and the temperature of the conveying medium needs to be lower than 200 DEG C, the push rod can be a servo push cylinder, the servo push cylinder needs to be used in cooperation with a controller, the position of the push rod pushing the valve core is controlled through the controller to realize accurate switching of the pipeline, and since it is a known prior art, no further description is given here.
