Two-stage combination valve of lipid filling

Abstract

The invention belongs to a filling valve suitable for the fields of liquid and lipid, and particularly discloses a two-stage combination valve of lipid filling. The valve comprises an inner valve and an outer valve sleeved outside the inner valve. The inner valve comprises a small-flow reset spring, an inner valve upper valve body, an inner valve lower valve body and an inner valve head, the inner valve head and the small-flow reset spring sleeved outside the inner valve head are arranged in the inner valve body, and the top portion of the inner valve head is fixed at the bottom end of a valve rod. The outer valve comprises an outer valve upper valve body, an outer valve lower valve body, an outer valve core (formed by the inner valve upper valve body and the inner valve lower valve body) and a large-flow reset spring, the inner valve body simultaneously serves as the outer valve core, the outer valve core and the large-flow reset spring are both sleeved on the middle portion of the valve rod, and the large-flow reset spring is arranged on the upper portion of the outer valve core. The two-stage combination valve is compact in structure, convenient to detach and clean and capable of adapting to flexible and variable production modes. When the two-stage combination valve is in a small flow, state of lipid flowing out of the valve body is stable and uniform, material blocking is thorough and fast, and filling accuracy can be ensured.

Description

technical field [0001] The invention belongs to a filling valve applicable to the fields of liquids, fats, etc., and in particular relates to a two-stage composite valve for fat filling which can ensure filling accuracy and stability of weighing filling equipment. Background technique [0002] At present, there are mainly two types of weighing type lipid filling valve machines in China: split filling machines with large and small valves and two-stage single-valve body filling machines. [0003] Large and small valve split filling machines usually use two large and small valve bodies for filling. When filling, first open the large valve body for large flow filling, then close the large valve body and open the small valve body for subsequent filling. The large valve body The filling ensures the filling speed, and the small valve body filling ensures the filling accuracy and the consistency of material cut-off. Although this filling method can ensure the filling accuracy and th...

Problems solved by technology

This kind of filling valve is no problem for liquid filling, but when it is used for lipid filling, when the valve body is in a low flow state, because the flow cross-sectional area of ​​the valve body outlet is a ring, the state when the lipid flows out is unstable , stick to each other, and fall into the product container in pieces of inconsistent size, so it is difficult to ensure the filling accuracy
