Summary of the invention
Technical problem to be solved by this invention provides a kind of antibiotic valve, to adapt to the requirement of fermented soy industry and medical and health industry.
For solving the problems of the technologies described above, the technical solution used in the present invention is that the advantage of the valve stem seal of the valve point sealing of the collection runner of getting stop valve, needle type valve and membrane valve is an one, forms a kind of antibiotic valve of new structure.Specifically: the one, valve body inlet channel longitudinal section is streamlined, and the runner end is circular-arc, and valve body inlet channel cross section is a heart-type, and described longitudinal section is meant the face that flows to of fluid, described cross section is meant and the perpendicular face of direction of flow face.The 2nd, the valve rod lower end is provided with the valve point, the valve point is a double sealing structure, described double sealing structure comprises the hard sealed department and the soft seal portion of different taperings, hard sealed department is linear sealing with the valve base sealing mouth top conical surface and contacts, soft seal portion is face seal with the valve seal mouth bottom conical surface and contacts, and the tapering of hard sealed department is greater than the tapering of soft seal portion.The 3rd, valve rod and valve gap are the diaphragm seal structure, and described diaphragm seal structure comprises diaphragm and barrier film lobe, and the barrier film lobe is contained in stem lower portion, the diaphragm two ends by valve gap by bolton on valve body, diaphragm is close to the barrier film lobe.The 4th, the bottom of valve body is provided with the discharging screw.
Beneficial effect of the present invention is: 1, the flow direction of fluid is determined in the longitudinal section of valve body, the cross section of valve body determines that fluid flows through the area of this section fluid, according to fluid mechanics principle, the longitudinal section of valve body is designed to streamline, the whole medium process of circulation does not have flex point and dead angle on the runner, rapid variation does not take place for flow direction and flow channel shape, can reduce fluid resistance, guarantee that runner is unobstructed; The cross section of valve body is designed to heart-shaped, and is big than circular cross-sectional area, helps flowing of working medium.2, the valve point adopts double sealing structure, to guarantee zero leakage, realizes sealing fully.3, valve rod and valve gap are the diaphragm seal structure, can effectively prevent the external leakage of valve stem.4, the bottom of valve body is provided with the discharging screw, sterilizes in pipeline residual gaseous emission and the production process when helping producing beginning; When not using screw, can block, can avoid the dead angle with plug screw.
The invention will be further described below in conjunction with the drawings and specific embodiments.
