Embodiment Construction

[0015] The accompanying drawings disclose a specific embodiment of the present invention in a non-limiting manner, which will be further described as follows in conjunction with the accompanying drawings.

[0016] See attached Figure 1~3 , the integrated anti-drip batching valve of the present invention is mainly composed of a two-position combination cylinder 1, a large flow cone valve, a small flow cone valve and two compression springs 5 ​​and 9, the small The flow cone valve is arranged in the large flow cone valve, and the opening and closing of the small flow cone valve and the large flow cone valve are controlled by a two-position combined cylinder and a compression spring.

[0017] The above-mentioned large-flow cone valve includes a cylinder 4, an end cover 3, a cone 16, a valve stem 7, a spring plate 8 and a piston head 10. The cone 16 is fixed on the front end of the cylinder 4, and the front end of the cone 16 is provided with a There is a discharge port 15, and ...

Abstract

The invention discloses an integrated anti-leakage type batching valve which mainly comprises a two-position combined cylinder, a large-flow conical valve, a small-flow conical valve and two compression springs, wherein the small-flow conical valve is arranged in the large-flow conical valve; and the opening and closing of the small-flow conical valve and the large-flow conical valve are controlled by the two two-position combined cylinder and the compression springs. The two-position combined cylinder can be controlled by an electromagnetic valve to produce three working states, namely a state that a material outlet is completely closed, a state that a small-aperture fine material outlet of the material outlet is opened and a state that the material outlet is completely opened. The integrated anti-leakage type batching valve has the advantages of compact and rational structure, good sealing property, high batching speed, high preparation precision and the like; the requirements on the batching speed and precision can be met, and meanwhile, the sanitary environment of a workshop is improved; and the integrated anti-leakage type batching valve is most suitable to be used in a batching system of a cigarette factory and is applicable to other automatic operation on liquid raw materials.

Description

technical field [0001] The invention relates to a liquid dispensing valve, in particular to a dispensing valve used in the automatic preparation of flavors and fragrances in cigarette factory threads, and belongs to the field of tobacco machinery. Background technique [0002] At present, there are mainly two types of raw material preparation and discharge valves used in cigarette factories: 1. Large and small pneumatic ball valves + throttle valves, 2. Valve positioner + V-shaped pneumatic ball valves. Among them, the structure of large and small pneumatic ball valve + throttle valve is mainly to connect a large diameter pneumatic ball valve and a small diameter pneumatic ball valve + throttle valve in parallel on the raw material discharge pipeline. The pneumatic ball valves are all open; when the precision is controlled, the large-diameter pneumatic ball valve is closed, and the raw material flows out from the pre-adjusted throttle valve and the small pneumatic ball valve...
