Description

Technical Field

[0002] The slurry valve adopts a special slurry flow channel design to increase the valve flow channel section and fluid channel to meet the flow requirements of high-concentration slurries. Slurry valves are often used in harsh working conditions such as slurries containing solid particles or high-viscosity liquids.

However, during long-term operation, particulate matter is likely to accumulate on the valve stem, and the valve stem is easily worn or blocked by particulate matter, and is not easy to clean, resulting in the valve failing to open and close normally. Therefore, it is often necessary to shut down the equipment and perform valve maintenance, which wastes time and affects production. In view of the deficiencies in the prior art, the utility model provides a Y-type slurry valve with a purgable valve stem and anti-crystallization to solve the above problems. Utility Model Content

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The embodiment of the present application provides a Y-type slurry valve with a purgeable valve stem and an anti-crystallization valve, which solves the problem that particulate matter is easily accumulated on the valve stem during the long-term operation of the slurry valve, the valve stem is easily worn or blocked by particulate matter, and is difficult to clean, resulting in the valve failing to open and close normally. Therefore, it is often necessary to shut down the equipment and perform valve maintenance, which wastes time and affects production.

[0022] During the use of the device, when there are particulate matter in the working conditions and these particulate matter accumulate on the valve stem, causing the valve to be stuck or blocked, the purge device 6 is designed to make the purge device 6 purge the surface of the valve stem body 4, and use a strong airflow to blow away the particulate matter accumulated on the valve stem, so as to regularly or as needed remove the accumulation on the valve stem body 4, ensure the smooth operation of the valve, and reduce downtime and maintenance time;

[0023] The purge device 6 is easy to operate. The air inlet pipe 602 passes through the valve cover 3 and extends outward. The air inlet pipe 602 is connected to the air pump. The air pump is used to output a strong airflow to the air inlet pipe 602. The airflow passes through the air inlet pipe 602 and enters the interior of the air inlet cavity 603, and then is discharged through the air outlet 604. The air outlet 604 is located at the position of the valve stem body 4, and the surface accumulation of the valve stem body 4 is cleaned, so that the accumulation falls into the valve cavity of the first valve body 1 and the second valve body 2.
