In the above various fields of application, the valves mainly used at present have the following disadvantages and shortcomings:
1. at present, the silo body discharge valve mainly adopts a stop type gate valve with a large drift diameter, and the gate valve is difficult to seal due to the large drift diameter, and the valve body and the gate plate are easy to deform to cause leakage.
2. At present, a paste distribution valve mainly adopted is a plate-type concentrated material distribution valve, but in the reversing process, a pipeline, a valve body pipe hole and a sealing device can be dislocated, so that the sealing is temporarily failed, high-pressure paste in the pipeline can be splashed out, the environment can be polluted, and the high-pressure paste distribution valve also has serious potential safety hazards.
3. Until now, no special paste pipeline stop valve exists, only a fluid stop valve can be used, but under the action of high pressure, solid components in paste easily enter a gap between sealing surfaces of the fluid stop valve and form wedge-shaped accumulation to block the valve.
4. For the shunt of the paste, the currently adopted rotary shunt valve is not only not uniform in shunt due to poor sealing, but also easy to release pressure, and the rotary shunt valve is not suitable for the shunt of materials in a conveying system with longer shunt branches and a conveying system with two branch pipes with larger length and pressure difference.
In order to solve the above problems, it is necessary to develop a new spool valve.
