Problems solved by technology

[0002] Phosphogypsum slurry is a mixture of solid, powder and liquid with high solid content, and it is easy to scale. It is easy to solidify when the temperature changes, and it is irreversible after solidification, which makes the existing valves easy to open and close. The situation caused serious problems in the equipment, resulting in the waste of a large amount of industrial raw materials, and the existing valves used for phosphogypsum slurry often need to stop production for valve maintenance and cleaning, which is very inconvenient. It is necessary to disassemble the valve for cleaning and maintenance, resulting in A large amount of raw material waste and stoppage in large tanks lead to economic losses. Therefore, there is an urgent need for a valve dedicated to phosphogypsum slurry.

Embodiment Construction

[0024] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a special valve for phosphogypsum slurry includes a valve body 1, the valve body 1 is provided with a valve stem 2, and the top of the valve stem 2 is provided with an operating mechanism 3, and the valve stem 2 The front end of the gate is provided with a gate 4, and the gate 4 is provided with a diversion hole 41. When the valve is fully opened, the diversion hole 41 is aligned with the flow channel of the valve body 1 after the valve is fully opened to form a straight pipe. After passing through the limit, it is aligned with the valve seat and the flow channel of the valve body to form a straight pipeline without sedimentation of medium and slurry. And the medium will not enter the middle cavity of the valve body after fully open...

Abstract

The invention relates to a special valve for phosphogypsum slurry and an on-line cleaning method. The special valve adopts a hard sealing plane structure and has a flushing function, and can flush liquid brought in during the opening and closing process. The special valve further has a blind plate function. Through the design of fastening bolts and adjusting screws which are arranged on a valve body, upper and lower cavities of the valve can be opened for descaling and removing cured materials during online operation, and the maintenance and cleaning work of the valve can be ensured to be carried out without halt production under any circumstances.

Description

technical field [0001] The invention specifically relates to the technical field of high-temperature valves, in particular to a special valve for phosphogypsum slurry and an online cleaning method. Background technique [0002] Phosphogypsum slurry is a mixture of solid, powder and liquid with high solid content, and it is easy to scale. It is easy to solidify when the temperature changes, and it is irreversible after solidification, which makes the existing valves easy to open and close. The situation caused serious problems in the equipment, resulting in the waste of a large amount of industrial raw materials, and the existing valves used for phosphogypsum slurry often need to stop production for valve maintenance and cleaning, which is very inconvenient. It is necessary to disassemble the valve for cleaning and maintenance, resulting in A large amount of waste of raw materials in the large tank and economic loss caused by shutdown, therefore, a special valve for phosphogy...
