Problems solved by technology

[0002] In the chemical, food, pharmaceutical, metallurgical and other fields, various tanks storing feed liquid are equipped with discharge valves for discharging feed liquid. The seal of the existing discharge valves generally adopts a simple single-wall and packing seal structure. When discharging, the connection part of the valve core is easy to leak the material liquid, and the material liquid usually has various chemical properties. If it is accidentally touched, it may cause harm to the human body and pose a safety hazard. Therefore, the sealing performance of the discharge valve is very good. important

Abstract

The invention relates to a seal baiting valve which comprises a valve seat, a valve body, a bracket, a connecting sleeve, a screw mandrel, a valve core and a hand wheel. The seal baiting valve is characterized in that the baiting valve is internally provided with a seal seat; the seal seat comprises a main body part and a plate part which is formed by the outward extending of the lower end of themain body part; the center of the main body part is provided with a center hole; the main body part is installed in the valve body and is sleeved on the valve core; the outer wall of the upper end ofthe main body part and the inner wall of the lower end of the center hole on the main body part are respectively provided with a seal groove; a seal ring is arranged between the outer wall of the upper part of the main body part and the valve body; two seal rings are arranged between the inner wall of the center hole of the main body part and the valve core; and the plate part is clamped between the valve body and the bracket. The seal baiting valve provided by the invention has the advantages of inventive and reasonable structure, novel seal mode, good sealing property, high safety, long service life and lower manufacturing cost, and is labor-saving and convenient because the hand wheel is adopted.

Description

technical field [0001] The invention belongs to the technical field of chemical machinery equipment, and in particular relates to a sealed discharge valve used in chemical production. Background technique [0002] In the chemical, food, pharmaceutical, metallurgical and other fields, various tanks storing feed liquid are equipped with discharge valves for discharging feed liquid. The seal of the existing discharge valves generally adopts a simple single-wall and packing seal structure. When discharging, the connection part of the valve core is easy to leak the material liquid, and the material liquid usually has various chemical properties. If it is accidentally touched, it may cause harm to the human body and pose a safety hazard. Therefore, the sealing performance of the discharge valve is very good. important. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a sealed discharge valve wi...
