Description

Mechanical valve for uninterrupted unidirectional delivery of two fluids and fluid delivery rod

Technical Field

The invention relates to the field of valves, in particular to a mechanical valve for uninterrupted unidirectional delivery of two kinds of fluids and a fluid delivery rod capable of uninterrupted unidirectional delivery of the two kinds of fluids.

Background

The sausage casing is an ideal material for filling various sausages, and the basic function of the sausage casing is to ensure that the sausages do not deteriorate under certain conditions so as to meet the requirements of storage and circulation. In the processing technology of the casing, the artificial casing wound into a disc shape is generally made into a hollow folded short sleeve in advance by adopting a shrinking device. Some artificial casings are processed by spraying liquid on the inner wall, such as some non-edible peeled casings, and after the sausage is filled, cooked and formed, the casings need to be peeled off in time, so that grease which is easy to peel off needs to be sprayed on the inner wall of the casings in advance. There are also edible collagen casings which require the avoidance of separation of the casing from the meat, and therefore require the spraying of a starchy medium on the inner wall of the casing which readily adheres to the meat.

In the prior art, intermittent shrinkage is usually adopted to inflate and spray liquid into the sausage casing synchronously. Gas is injected and liquid is injected into the sleeve shrinkage rod by using the butt joint rod or the holding rod clamp, when a sleeve shrinkage rod of a section of sausage casing is required to be dismounted after the sleeve shrinkage of the section of sausage casing is finished, the butt joint rod or the holding rod clamp needs to leave the sleeve shrinkage rod, the gas injection and the liquid injection are stopped, the sleeve shrinkage is suspended until the butt joint rod or the holding rod clamp is connected with the sleeve shrinkage rod again, and the next sausage casing can be shrunk.

Although the intermittent sleeving and shrinking machine can realize liquid spraying in the sleeving and shrinking rod, the intermittent sleeving and shrinking production efficiency is lower. Moreover, each sausage casing needs to be shrunk once, so that the shrinking effect is often influenced, and the defective rate is increased.

FIG. 1 shows a schematic cross-sectional view of a fluid transport rod from above. Two

mechanical valves

100 and 200 are shown in the fluid delivery wand 20 shown in figure 1. It should be understood that, according to actual needs, a person skilled in the art may further provide more mechanical valves downstream of the first mechanical valve 100 and/or upstream of the second mechanical valve 200. In the present invention, at least two

mechanical valves

100 and 200 are used in combination to ensure that the two

fluids

10a and 10b are continuously delivered in the pipeline when the two fluid sources are switched from one mechanical valve 100 to the other mechanical valve 200 to input the two

fluids

10a and 10 b. Since the first mechanical valve 100 and the second mechanical valve 200 have the same structure, the present invention will be described below mainly with reference to the first mechanical valve 100.

As shown in fig. 3 and 4, the first mechanical valve 100 includes: a first external input port 102a for inputting a first fluid 10 a; a second external input port 102b for inputting a second fluid 10 b; a first cavity 104a, wherein the first cavity 104a is designed to allow the first fluid 10a to flow into the first cavity 104a in a single direction through the first external input port 102 a; the first cavity 104a has a first internal input port 106a and a first internal output port 108 a; and a second cavity 104b, said second cavity (104b) being designed for unidirectional flow of said second fluid 10b into said second cavity 104b through said second external input port 102 b; the second cavity 104b has a second internal input port 106b and a second internal output port 108 b.

In the fluid transfer rod 20 shown in fig. 1, the first mechanical valve 100 is located downstream and the second mechanical valve 200 is located upstream in the flow direction of the fluid. Therefore, the first internal input port 106a is designed to communicate with the second internal output port 108b of the adjacent second mechanical valve 200 disposed upstream in the fluid flow direction, while the first internal input port 106a of the second mechanical valve 200 is blocked. The first internal output port 108a of the first mechanical valve 100 is designed to communicate with an outlet of a pipe to output the first fluid 10a, and the first internal output port 108a of the second mechanical valve 200 communicates with the second internal input port 106b of an adjacent first mechanical valve 100 disposed downstream in the fluid flow direction. The second internal input port 106b of the first mechanical valve 100 is designed to communicate with the first internal output port 108a of the adjacent second mechanical valve 200 disposed upstream in the fluid flow direction, and the second internal input port 106b of the second mechanical valve 200 is blocked. The second internal output port 108b of the first mechanical valve 100 is designed to communicate with the outlet of the pipe to output the second fluid 10b, and the second internal output port 108b of the second mechanical valve 200 communicates with the first internal input port 106a of the adjacent first mechanical valve 100 disposed downstream in the fluid flow direction. That is, the first and second internal input ports of the mechanical valve located most upstream of the fluid delivery wand 20 are blocked, ensuring that both fluids flow in one direction. The first and second internal output ports of the mechanical valve located most downstream of the fluid delivery rod 20 communicate with the output ports of the conduits to output the first and second fluids.

Further, as shown in fig. 1 and 2, a first elastic member 110a and a first sealing ring 112a are disposed in the first cavity 104 a. When the first fluid 10a is input from the first external input port 102a, the pressure of the fluid forces the first sealing ring 112a to move into the first cavity 104a and compresses the first elastic member 110a, thereby flowing into the first cavity 104 a. When the first fluid 10a stops being input from the first external input port 102a, the first elastic member 110a is released to push the first sealing ring 112a to move toward the first external input port 102a, so as to seal the first cavity 104a and prevent the first fluid 10a from flowing out. Of course, it should be understood that other solutions in the prior art can be adopted by those skilled in the art to ensure the unidirectional fluid flow and prevent the outflow of fluid, and the solution is not limited to the solution of adopting the elastic element to cooperate with the sealing ring.

A second elastic member 110b and a second sealing ring 112b are arranged in the second cavity 104 b. When the second fluid 10b is input from the second external input port 102b, the pressure of the fluid forces the second sealing ring 112b to move into the second cavity 104b and compresses the second elastic member 110b, thereby flowing into the second cavity 104 b. When the second fluid 10b stops being input from the second external input port 102b, the second elastic member 110b is released to push the second sealing ring 112b to move toward the second external input port 102b, so as to seal the second cavity 104b and prevent the second fluid 10b from flowing out. Of course, it should be understood that other solutions in the prior art can be adopted by those skilled in the art to ensure the unidirectional fluid flow and prevent the outflow of fluid, and the solution is not limited to the solution of adopting the elastic element to cooperate with the sealing ring.

As further shown in fig. 1 and 2, a first step 114a is formed between the first cavity 104a and the first internal input port 106a for abutting against the first resilient member 108 a. A second step 114b is formed between the second cavity 104b and the second inner output port 108b for abutting against the second elastic member 108 b. Of course, it should be understood that, in order to limit the elastic member in the cavity, one skilled in the art can fix one end of the elastic member in the cavity, and the technical solution of the step is not limited.

Further, the first internal input port 106a and the second internal input port 106b are designed as unidirectional input ports. Therefore, when the first and second

external input ports

102a and 102b stop inputting fluid, the first and second internal input ports are pressed to open in one direction, and fluid input from the second mechanical valve 200 passes through the first and second internal input ports, so as to ensure that the two-way fluid flows out of the output ports in the pipe without interruption.

Further, as shown in fig. 1 and 2, the first external input port 102a and the second external input port 102b are disposed opposite to each other in the radial direction of the pipe. The first cavity 104a and the second cavity 104b are disposed opposite to each other along the axial direction of the duct. By adopting the structure, the structure of the valve can be very compact and the injection of the fluid is convenient. Thus, the valve of the application has a very outstanding advantage when applied to small-sized pipelines. Of course, it should be understood that other structural designs may be adopted by those skilled in the art, and are not limited thereto.

As will be readily appreciated from the foregoing description, the present invention also provides a fluid transfer bar 20, the fluid transfer bar 20 including at least two mechanical valves as described above, the at least two mechanical valves cooperating to ensure that when two fluid sources are switched from one mechanical valve to the other mechanical valve to input two fluids, the two fluids are continuously transferred in the lines of the transfer bar. It should be understood that, according to actual needs, a person skilled in the art may further provide more mechanical valves downstream of the first mechanical valve 100 and/or upstream of the second mechanical valve 200.

Those skilled in the art with access to the teachings herein will be able to devise many other embodiments and applications which fall within the spirit and scope of the present invention.
