Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, the bottom of the cylinder 1 is fixedly installed on the top of the cylinder mount 15 by four bolts, and the four bolts are evenly arranged along the circumference of the cylinder mount 15 . The bottom of the cylinder mounting seat 15 and the top of the outer filling valve body 12 are fixedly connected by four bolts, and the connecting part of the two is located outside the valve body of the liquid filling compound valve. Circumferentially evenly arranged. The bottom of the cylinder rod 17 of the cylinder 1 is screwed and fixedly connected with the valve rod connector 16 , and the valve rod connector 16 is clamped and connected with the top of the valve rod 3 .

[0020] Such as figure 1 As shown, the circular shoulder on the top of the outer filling valve body 12 cooperates with the circular hole at the low...

Abstract

The invention relates to a filling valve for liquid filling machines, in particular to a liquid filling combined valve with the function of negative pressure suction. The liquid filling combined valve comprises an inner negative pressure suction valve and an outer filling valve sleeved outside the same. The inner valve and the outer vale share a stem. The upper portion of the stem is located outside the outer filling valve. The lower portion of the stem serves as an upper valve block of the inner negative pressure suction valve. A cylinder driving the stem to linearly reciprocate is disposed at the top end of the stem. The liquid filling combined valve with the function of negative pressure suction is compact and simple in structure. When closed, the liquid filling combined valve is capable of sucking filling material which drops, so that dropping is prevented effectively and package pollution is prevented. When opened, the liquid filling combined valve discharges the sucked material to material flow, so that maintenance cost is lowered and waste of the material is lowered.

Description

technical field [0001] The invention relates to a filling valve for a liquid filling machine, in particular to a liquid filling composite valve with a negative suction function for weighing filling equipment to ensure filling accuracy and prevent dripping. Background technique [0002] At present, there are two main forms of drip prevention for the valve body of domestic weighing liquid filling machines: adding a feeding tray and adding a negative suction device. [0003] Adding a receiving tray can prevent most dripping but cannot be avoided completely, and it will affect the filling speed, especially on the rotary weighing filling machine, due to the limitation of space and structure, it is impossible to add a receiving tray. Adding a negative suction device can solve the problem of dripping while ensuring the filling speed, but the current way to install a negative suction device is to design a through hole in the center of the filling head, and then design a set of negat...
