Abstract

The invention relates to a shear rotary valve comprising a valve body and a valve element arranged in a valve cavity of the valve body. The valve body is provided with a discharging opening communicating with the valve cavity, a first feeding opening and a second feeding opening, the valve element is provided with a cutting edge, the discharging opening and the first feeding opening are alternatively opened and closed when the valve element rotates in the valve cavity, and the cutting edge is driven to shear materials flowing through the discharging opening and the first feeding opening. An oil immersion type shear rotary valve plunger pump comprises a material cylinder, a driving device and the shear rotary valve, a piston is arranged in the material cylinder and divides an inner cavity of the material cylinder into a first cavity and a second cavity, the first cavity of the material cylinder communicates with the second feeding opening of the shear rotary valve, the driving device isarranged at the end, close to the second cavity, of the material cylinder, and the output end of the driving device is connected with the piston. During reversing of the valve element, the cutting edge can shear particles in the materials through power of reversing of the valve element, blocking or stalling of the valve element due to the particles in the materials is avoided, and the feeding accuracy is improved.

Description

technical field [0001] The invention relates to the field of packaging equipment, in particular to a shear rotary valve and an oil-immersed shear rotary valve plunger pump containing the same. Background technique [0002] The oil-immersed shear rotary valve plunger pump is the feeding part of the small bag packaging machine, mainly used in bagged food and chemical batch packaging, and the plunger pump is divided into mechanical drive type and pneumatic type, because of high production efficiency, plunger It has the characteristics of high measurement accuracy and can quantitatively transport materials such as viscous bodies and viscous bodies containing particles, and is currently widely used. [0003] At present, when the viscous body containing particles is quantitatively transported, due to the existence of particles (such as: bones, chili seeds, peppercorns, various plant fibers, etc.), the shear rotary valve in the oil-immersed shear rotary valve plunger pump will The...
