Filling gun

Abstract

The invention provides a filling gun, comprising a regulating nut, an air cylinder, a gun body support, a fluid body feed inlet, a fluid body discharge hole, a sealing part and a gun head, wherein, the gun head comprises a valve plug, an air cylinder bar of the air cylinder is connected with the draw bar of the valve plug; the opening and closing of the valve plug are controlled by the air cylinder; the regulating nut is used for regulating the opening of the valve plug to control the flow rate of the fluid body; and the sealing part is connected with the gun body support and the gun head, and comprises draw bar seal, chevron seal and clearance seal. By the sealing part of the filling gun provided by the invention, the leakage probability of the raw materials can be greatly lowered, the unnecessary waste is avoided, the service life of the equipment is improved, the washing and maintaining frequency of the equipment can be lowered, and the labor intensity of the operators and the maintenance cost can be lowered.

Description

technical field [0001] The invention relates to a fluid filling device, in particular to a fluid filling gun with good sealing performance. Background technique [0002] In industry, it is often necessary to quantitatively fill fluids, that is, inject the required fluid from a large container into a designated container through quantitative filling equipment. Such as Figure 5 A prior art filling gun equipment shown is a commonly used quantitative filling equipment. The filling gun includes an adjusting nut 1 , a cylinder 3 , a gun body bracket 5 , a fluid inlet 901 , a fluid outlet 902 , a sealing member 20 and a gun head 9 . The gun head part includes the valve core 15, the cylinder rod 301 of the cylinder 3 is connected with the valve core rod 13, the opening and closing of the valve core 15 is controlled by the cylinder 3, and the adjusting nut 1 is used to adjust the opening of the valve core 15 to control the flow of the fluid. flow rate; the sealing member 20 connec...

Problems solved by technology

The gun head part includes the valve core 15, the cylinder rod 301 of the cylinder 3 is connected with the valve core rod 13, the opening and closing of the valve core 15 is controlled by the cylinder 3, and the adjusting nut 1 is used to adjust the opening of the valve core 15 to control the flow of the fluid. flow rate; the sealing member 20 connects the gun body support 5 and the gun head part 9, in order to prevent the leakage of the fluid when filling, in the filling gun of the prior art shown in the figure, two O-rings 202 are used to carry out the gun The sealing of the body bracket 5 and the gun head part 9, this sealing method cannot seal the pull rod, which is likely to cause leakage of raw materials and waste of materials; if the raw materials are corrosive or other harmful materials, it will cause serious damage to the operator. In addition, the leakage of corrosive raw materials will also cause harm to the equipment; and the leakage caused by poor sealing will increase the frequency of equipment cleaning and increase the labor burden and intensity
