The invention provides a pharmaceutical water sampling valve, and belongs to the field of the pharmaceutical technology. The pharmaceutical water sampling valve comprises a valve body, a plug, a valveelement and a handle. The plug and the valve element are mounted in the valve body. The valve element and the plug are fixedly connected in a threaded manner. The left end face of the plug is flushedwith the left end face of the valve body. A first gasket is arranged at the joint of the plug and the valve body. An O-shaped ring is arranged on the valve element. A spring is mounted on the valve element. A sealing plate is arranged on the right side of the spring. The handle is arranged at the right end of the valve element. A second gasket is arranged at the joint of the valve element and thevalve body. A third gasket is arranged at the joint of the valve element and the sealing plate. The pharmaceutical water sampling valve is reasonable in structure and convenient to use; the end faceof the plug is flushed with that of the valve body, and no liquid is accumulated at a feeding opening; the valve is connected with equipment in a welded manner, a welding groove is arranged on a welding joint, the welding bead is level, and liquid is not prone to being accumulated at the welding position; the surfaces of the valve body and the valve element are subjected to mirror polishing, and the liquid discharging performance is good; and through the arrangement of sealing gaskets, the sealing effect is good, outside germs are effectively isolated from entering the equipment, and water pollution is avoided.
Description
technical field [0001] The invention relates to a sampling valve, in particular to a pharmaceutical water sampling valve. Background technique [0002] Sampling valve is a valve used to obtain medium samples in pipelines or equipment. In many occasions that require frequent chemical analysis of medium samples, special sampling valves are used. Sampling valves are widely used in food, pharmaceutical, chemical, biological and other industries. [0003] Pharmaceutical water is widely used in the fields of pharmaceutical production and biotechnology. The quality of purified water and water for injection directly affects the quality of pharmaceutical production. A sampling valve is installed in the pharmaceutical water system to detect the water quality to prevent water pollution from affecting the quality of pharmaceuticals. [0004] The existing sampling valve has poor sealing performance, and microorganisms can easily enter the valve body, and enter the pipeline or equipment ...
