Problems solved by technology

The filling valve with such a structure is not suitable for filling liquids containing particles, such as fruit juice or milk products with fruit pieces, because the particles may come out of the liquid outlet of the infusion channel and then enter the exhaust pipe from the air inlet of the exhaust channel. Medium, affecting normal exhaust
In addition, during the opening and closing process of the filling valve, after the particles are clamped between the above-mentioned slope and the chamfer, the tight fit between the slope and the chamfer cannot be guaranteed, so the liquid outlet of the infusion channel is not closed tightly, and leakage will occur

Embodiment 1

[0030] Such as Figures 1 to 7 Shown is an embodiment of a filling valve of the present invention, which includes a valve body 1, a valve sleeve 2 and an exhaust pipe 3, the valve body 1 has a valve cavity 10, the valve sleeve 2 has an axial through hole 21, and the shaft The through hole 21 is a round hole, the top of the valve sleeve 2 extends into the valve cavity 10, the bottom end of the valve sleeve 2 is located outside the valve body 1, and there is a valve between the valve sleeve 2 and the valve body 1 for driving the valve sleeve 2 and the valve body. The spring 4 of body 1 back movement, the upper end of spring 4 is positioned by the step position of valve body 1 outer side wall, and the lower end of spring 4 is then positioned by the projection body lower end of valve sleeve 2 outer side wall. The outer wall of the valve body 1 has a protruding portion 12. The protruding portion 12 can be a block structure and is molded together with the valve body 1. The upper end...

Embodiment 2

[0039] Such as Figure 8 As shown, the structure of the filling valve is basically the same as that of Embodiment 1, the difference is that the limit block 73 is fixed in the limit groove 72 of the valve sleeve 2, and the installation hole 71 has a certain Length, in the natural state, the limit block 73 is in contact with the top side wall of the mounting hole 71, and as the valve sleeve moves toward the valve body, the limit block 73 gradually approaches the bottom wall of the mounting hole 71, and the end surface of the shaft shoulder After 511 is exposed outside the bottom end of the valve sleeve, the limit block 73 contacts the bottom side wall of the mounting hole 71, and the valve sleeve stops moving relative to the valve body.

Abstract

The invention provides a loading valve. The loading valve comprises a valve body, a valve sleeve, and an exhaust pipe; the valve body is provided with a valve cavity, the valve sleeve is provided with an axial through hole, the top end of the valve sleeve stretches into the valve cavity, the bottom end of the valve sleeve is arranged outside the valve body, a spring which can drive the valve sleeve to move in the opposite direction relative to the valve body is arranged between the valve sleeve and the valve body; an anti-separation structure for preventing the valve sleeve from being separated from the valve body is arranged between the valve body and the valve sleeve; the loading valve also comprises a liquid feeding pipe, a first gap is arranged between the liquid feeding pipe and the valve body, a second gap is arranged between the liquid feeding pipe and the valve cover, the bottom end of the liquid feeding pipe is connected to a liquid discharge part, the outer diameter of the liquid discharge part is larger than the outer diameter of the liquid feeding pipe, the joint part between the liquid feeding pipe and the liquid discharge part forms an end face of shaft shoulder, and the side wall of the liquid discharge part is provided with a liquid outlet. The loading valve is especially suitable for loading liquid containing particles, the valve sleeve will not be separated from the valve body, the particles cannot be easily left, and the installation and disassembly of the loading valve are both convenient.

Description

technical field [0001] The invention relates to a filling equipment accessory, in particular to a filling valve. Background technique [0002] Such as Figure 9 As shown, the filling valve used in the negative pressure filling technology includes a valve body 01, a valve sleeve 02 and an exhaust pipe 03. Both the valve body and the valve sleeve are of tubular structure. One end of the valve sleeve extends inside the valve body, and the other end is located outside the valve body. A flange is provided on the valve sleeve, and a spring 04 is arranged between the valve sleeve and the valve body. One end of the spring is restricted by the flange, and the other end of the spring is restricted by the valve body. The exhaust pipe is fixedly connected with the valve body through the mounting seat 06. The length of the exhaust pipe is much longer than the length of the valve body. One end of the exhaust pipe is provided with a raised edge 031, and the raised edge is provided with a...
