Description

[Detailed description of the invention] This invention relates to an outlet for intermittently taking out highly viscous foods such as fresh cream, miso, kamaboko raw materials, sausage raw materials, and hamburger steak raw materials from processing equipment or storage tanks to the outside world. .

Conventional cock stopcocks used as this type of outlet usually have a cylindrical flow hole with the inlet and outlet having the same diameter.

To explain this using FIGS. 3 and 4, 21
is a cylindrical outer shell, one end of which is a closed part 21a, and the other end is open, and has an inlet 22 on one of its peripheral walls and an outlet 23 at a symmetrical position. The diameters of the outflow ports and the outflow ports are both D and are equal to each other.

A cylindrical stopcock 26 is accommodated in the outer shell 21 in close contact with its inner peripheral surface, and the stopcock 26 has a cylindrical flow hole 27 perpendicular to its central axis. The inner diameter of 27 is also D.

In addition, 24 is an inflow pipe connected to the inflow port 22, 25 is a connecting thread formed on the outer periphery of the end of the inflow pipe 24, 28 is a steel ball,
29 is a thread formed on the outer periphery of the open end of the outer shell 21; 30 is a lid screwed onto the thread 29; 31 is a center hole of the lid 30;
2 is an elastic annular backing interposed between the inner surface of the lid 30 and the stopcock 26; 33 is a solenoid mounting bracket; 34 is a rotating solenoid; 35 is a rotating shaft of the rotating solenoid 340; 36
is a key that non-rotatably connects the rotating shaft 35 to the hole 37 in the end face of the stopcock 26.

When the rotary solenoid 34 is not energized,
The communication hole 27 of the stopcock 26 is in a closed state, facing the direction indicated by dotted lines 38 and 3B in FIG.
Turn to the direction shown by the solid line in the figure and switch to the open state.

In the conventional cock as described above, the stopcock 26 needs to be rotated approximately 900 times to open and close, and especially in the case of high viscosity liquid, the energy required for opening and closing is considerable, and when closing, the stopcock surface is heated through the outlet 23. Since a large area is exposed to the atmosphere, there are problems such as a large negative effect when handling liquids that do not like contact with the air.

If we only want to reduce the rotation angle required to open and close the cock and reduce the exposed surface of the stopcock when it is closed, the diameter of the stopcock can be left as is, and the inlet 22,
It is only necessary to reduce the diameters of the outlet 23 and the flow hole 27.

However, if you do so, the flow path of the high viscosity liquid will be
Because it is rapidly constricted in the second part, it becomes stagnant here and cannot flow smoothly.

The purpose of this invention is to reduce the rotation angle required to open and close the stopcock while preventing stagnation of the flow of highly viscous liquid as much as possible, and to reduce the surface of the stopcock that is exposed when the stopcock is closed.

This invention uses a cock with a rotating stopcock as described above.

In that case, the width of the outflow port along the rotational direction of the stopcock is selected to be smaller than the width of the inflow port also along the rotational direction of the stopcock, and the width of the flow hole of the stopcock is selected to be approximately equal to the width of the above-mentioned inflow port on the inflow side. By selecting the stopcock approximately equal to the outlet, the angle of rotation of the stopcock required for opening and closing is reduced, and the surface of the stopcock exposed when closing is reduced.

Furthermore, inside the stopcock, the width of the flow hole changes smoothly from the inflow side to the outflow side, thereby preventing stagnation in the flow of the highly viscous liquid.

This invention will be explained below based on the embodiments shown in FIGS. 1 and 2.

1 is a cylindrical outer shell, one end of which is a closed part 1a, the other end is open and buttoned, and one of its peripheral walls has an inlet 2;
It has an outlet 3 at a symmetrical position.

The diameter Di of the inlet 2 is the diameter of the outlet 3. It's more like a dog.

An inflow cylinder 4 is connected to the inflow port 2 and has a connecting thread 5 on the outer periphery of the end thereof.

A cylindrical stopcock 6 is accommodated in the outer shell 1 in close contact with the circumferential surface of the hook, and the stopcock 6 has a communication hole 7 perpendicular to its central axis.

The inner diameter of the flow hole 7 is Di on the inlet 2 side and on the outlet 3 side.
Beams on the side.

't1', and the middle thereof forms a conical shape and changes continuously.

8 is a steel ball interposed between the center of the end surface of the stopcock 6 and the center of the outer shell closing portion 1a.

A lid 10 is screwed into a thread 9 provided on the outer periphery of the open end of the outer shell 1.

The lid 10 has a central hole 11, and a resilient annular backing 12 is interposed between its inner surface and the end surface of the stopcock 6.

A rotary solenoid 14 is attached to the outer surface of the lid 10 with a fitting 13.

A rotating shaft 15 of the rotating solenoid 14 is inserted into a hole 17 formed in the end face of the stopcock 6 using a key 16 so that it cannot be slid.

Incidentally, the stopcock 6 may be a cone whose diameter is reduced on the side of the outer shell closing portion 1a, the shape of the outlet 3 is oval, and the length of the stopcock 6 in the axial direction is equal to that of the inlet 2. The diameter may be approximately the same as that of the diameter.

As shown in FIG. 2, the outlet can be opened and closed by a slight rotation of θ.

Therefore, not only is it easy to manufacture a rotational drive mechanism for the operation, but also the operation is efficient when manual operation is used.

Since the surface area of the stopcock that is exposed to the outside air through the outlet 3 when closed is small, it is suitable for opening and closing fluids that do not like long-term contact with air. The advantage is that highly viscous foods can be processed smoothly due to the fact that the inside is filled with liquid and the internal dimensions of the flow holes 7 change continuously.

Therefore, it is particularly suitable for controlling the distribution when measuring and filling fresh cream into containers.
