Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a solid particle sampling valve. Background Art

[0002] A sampling valve is a valve device used to obtain material samples. It is commonly used in industrial processes, especially in the production processes of chemical, petroleum, food, pharmaceutical and other fields. The sampling valve can be used to collect liquid, gas or solid samples for analysis, testing, quality control or other purposes.

[0003] In industrial production, production materials must be tested and analyzed at regular intervals to obtain various technical information, and then the production process can be adjusted in a timely manner. Other industrial productions also have this process, except that different industrial productions use different samples and sampling methods. Solid particles can easily deposit in the sampling valve sampling tube and inside the sampling valve, causing the valve channel to be blocked; and if blockage occurs, the valve can only be disassembled, causing great inconvenience.

The sampling valve body has a certain curvature and is fixedly installed on the wall of the tank equipment. The sampling tube is installed in the sampling valve body and extends into the tank body through a reserved hole in the tank body for sampling. The push rod is threadedly connected to the sampling tube to push the sampling tube to perform linear motion in the sampling valve body. The limit sleeve is used on the push rod to prevent the push rod from moving beyond the limit. The packing is filled between the sampling valve body and the limit sleeve. The pressure cover is pressed on the packing. The purge port is installed outside the sampling valve body. The purge port passes through the sampling valve body to purge the sampling tube. The air seal is installed on the outside of the sampling valve.

[0007] Furthermore, the actuator cylinder assembly for driving the sampling valve includes a linear cylinder, a limit switch and a support frame. The linear cylinder is connected to the push rod, the limit switch is installed on the linear cylinder, and the support frame is connected to the linear cylinder and fixed on the wall of the equipment.
