The balancing hole in the secondary valve disc cavity is provided with a secondary valve seat that cooperates with the secondary valve disc to form an opening and closing mechanism.

[0004] The stop valve in this patent is similar to most other stop valve structures in the prior art, and has the following disadvantages: the connection lengths at both ends of the stop valve are fixed and cannot be adjusted. When the distance between the two pipes to be connected is large and the stop valve cannot connect them, it takes a lot of time to solve the problem of insufficient pipe length. Utility Model Content

[0020] Example: As shown in the attached Figures 1 to 4 The shown type of telescopically installed stop valve includes a valve body 1, which is provided with a switch assembly. The switch assembly includes a valve core 2 arranged in the valve body 1, a valve stem 3 rotatably connected to the valve core 2, and a nut sleeve 9 threadedly connected to the outside of the valve stem 3. A valve cover 5 is detachably fixedly connected to the valve body 1, a sealing ring 4 is provided between the valve cover 5 and the valve body 1, a fixing bolt 6 is provided on the outside of the valve cover 5, the fixing bolt 6 is threadedly connected to the valve body 1, a fixing seat 8 is fixedly connected to the outside of the valve cover 5, the nut sleeve 9 is rotatably connected to the fixing seat 8, a handwheel 10 is fixedly connected to the top of the valve stem 3, a packing is provided between the valve stem 3 and the valve cover 5, a pressing sleeve 7 is provided on the outside of the valve stem 3, the pressing sleeve 7 is in contact with the outside of the packing, and the pressing sleeve 7 is detachably fixedly connected to the outside of the valve cover 5. The valve stem 3 is driven to rotate by rotating the handwheel 10, and the valve stem 3 is driven by the action of the nut sleeve 9 to drive the valve core 2 to move upward or downward, thereby realizing opening or closing of the valve body 1.

[0021] Among them, both ends of the valve body 1 are detachably fixedly connected with a connecting pipe 11, one end of the connecting pipe 11 is provided with an adjusting pipe 12, one end of the adjusting pipe 12 is fixedly connected with a sealing gasket 18, a rubber tube 13 is provided between the connecting pipe 11 and the adjusting pipe 12, and the two ends of the rubber tube 13 are respectively fixedly connected to the connecting pipe 11 and the adjusting pipe 12, and a fixing component is provided between the connecting pipe 11 and the adjusting pipe 12. When the size of the valve body 1 is not enough and the pipelines cannot be connected, it is only necessary to remove the long bolt 17 and pull the adjusting pipe 12 outward to increase the length between the adjusting pipe 12 and the connecting pipe 11 through the rubber tube 13, thereby increasing the connection length of the valve body 1, and then fixedly connecting the adjusting pipe 12 to the corresponding pipeline.

[0022] In a further design, multiple groups of reinforcing ribs 14 are fixedly connected in the rubber tube 13. The reinforcing ribs 14 are steel wires or iron wires, preferably steel wires, which are used to increase the strength of the rubber tube 13 so that the rubber tube 13 has sufficient strength to support the transportation of liquid, thereby ensuring the stability of the valve body 1 when transporting liquid.

[0025] When installing the valve body 1, the two ends of the regulating tube 12 are fixedly connected to the corresponding pipes respectively, and the valve stem 3 is driven to rotate by turning the hand wheel 10. Under the action of the nut sleeve 9, the valve stem 3 drives the valve core 2 to move upward or downward, thereby opening or closing the valve body 1;

[0026] When the size of the valve body 1 is not enough to connect the pipes, it is only necessary to remove the long bolt 17 and pull the regulating tube 12 outward to increase the length between the regulating tube 12 and the connecting pipe 11 through the rubber tube 13, thereby increasing the connection length of the valve body 1, and then fix the regulating tube 12 to the corresponding pipe. When transporting liquid, the liquid can be transported through the expanded rubber tube 13.
