Description

The subject of the invention is a valve, in particular for pipes in a milling industry, which serves to transport in an unchanged direction and / or to deflect and / or separate and / or isolate substantially granular or dusty material flowing through the pipe. Each valve comprises an internal passage chamber and at least two openings lead to the internal chamber, namely at least one inlet and one outlet. At least one insert is placed in the inner chamber of the valve, allowing the flow and / or diverting of the material conveyed through the conduit and / or shutting it off, the outer casing being in the form of a sphere or having spherical parts.

In the milling industry, the so-called drop tubes that point substantially from top to bottom can be connected to each other in various ways. Fittings are known that are capable of changing the direction of the material transported in a pipe. Among them, there may be mentioned relatively simply constructed connecting elements which allow a change of direction with a certain angle of inclination, so-called articulated elbows and elbows with a variable angle of inclination.

It is also known to make the latter in the form of ball-joint elbows. In this case, the articulation is formed by an outer spherical ball that twists over the outer spherical cap. For mounting in any angular position, a crimp clamp is located on the outside.

For separation or joint transmission of the particulate material or the kind of dust u ^L d ^{C h} ndejsc used si.e so-called ^{U-section path 180} of the branch. The separation of the transported material follows · ^h o ^t by adapting these ukac ^{wit h 180} ° fertility ^sid floating plate or directional flaps. An embodiment is also known in which the guide plate or the flap takes one position and one position or the other or branch pipe outlet takes the closed position.

Tubular shut-off valves in the milling industry also work according to the above principles. This applies to fittings known so far in milling, which are used to solve various technological tasks depending on the different structure. Such valves can be found, for example, in the product catalog of Jacob, Germany.

The known fittings are manufactured from metal, essentially welded, with the exception of articulated valves. Metal fittings are heavy in the larger diameters required in the mill industry and can be attached to flanged pipe ends.

This requires the use of additional connecting elements and additional seals in order to prevent the influence of the transported material.

The object of the invention is to construct valves, composed of modular elements, which consist of cost-effective, easily assembled elements, organically connected and interchangeable with each other.

The task of the invention is to develop a pipe connector that meets all the technological requirements of the milling industry, i.e. changing direction, separating, guiding, switching to another direction, cutting off the transported material in the pipeline for inspection and sampling, using the same elements of one type of valve .

The idea of the invention is to take advantage of the fact that the spherical body can be placed as an insert in a spherical cup-like housing and the insert can thus be rotated spatially. One or more openings in common may be provided in the housing and the insert, and the opening passes intentionally through the center of the ball, if the spherical housing turns on the spherical insert, the outlet openings of the housing are closed. However, it is always possible to find at least one position in which the openings in the housing and in the insert assume the transmission position by rotating.

Further, the essence lies in the fact that the spherical housing and the spherical insert therein can be cut into two equal parts in such a way that their passage opening axis forms an angle with the intersection surface deviating from the right angle. If the halves consisting of the insert and housing parts rotate in the plane of intersection, and the parts in the halves do not shift each other, then the angle between the axes of the holes in the halves with respect to the initial state changes. As a result, it is possible to change the direction of the pipes adjacent to the outlet openings of the spherical cup-shaped housing.

If one of the two halves remains stationary and the other fully rotates, then the outlet of the rotated half defines a circular path, the plane of the circular path is parallel to the intersection surface, and the radius of the circular path depends on the angle between the intersection surface and the hole axis. The more the angle between the intersection surface and the hole axis deviates from the right angle, the greater the radius of the circular path.

A further effect resulting from the above is that the angle between the cut surface and the axis of the opening determines the maximum deviation in the angle of the possible positions of the tubular conduit connected to the spherical bowl housing outlet opening. Within the limits of the maximum deviation of the angle, the axes of the through-hole and the tubing connected to the openings can be turned to any angular position by turning.

It is also an idea of the invention that the spherical inserts are movable inside the spherical cup-shaped housing independently of each other and from the housing, and their openings may form a closed or open position. This finding is based on the design of the diverting, replaceable and shut-off valves, consisting of a spherical bowl housing and spherical inserts.

This task is solved by the valve according to the invention, in particular for pipes in the milling industry, which serves to transport in an unchanged direction and / or to divert and / or to separate and / or cut off substantially granular or dusty material flowing through the conduit. tubular, which has a passage chamber inside, at least two openings are connected to the internal chamber, i.e. at least one inlet and one outlet, at least an insert, permitting passage and / or changing the direction of the material flowing in the conduit 1 / or shut-off its passage in the inner chamber of the valve, and the outer casing is spherical or includes spherical parts, which is shaped so that the spherical parts are formed by at least two spherical ball housings connected to each other, and the housings connected to each other by a keyway joint allowing elastic

162 268 displacement, the key joint being formed in one housing by a keyway fold, and in the other housing attached by a keyway receiving a key, the dimensions and shape of key and groove are matched to each other and allow for mutual rotation, and the spherical ball housings form valve, have overlapping or intersecting axes of rotation and one or more rotational surfaces forming with the axes of rotation, preferably the same angle, deviating from the right angle, also constituting a dividing plane, with a replaceable insert placed in the inner chamber of the housing and the inserts have a spherical surface that fits on the outside with the spherical cap housings, and a uniform pivot surface, and inside one or a series of hollow passage chambers, the replaceable insert is secured by a detachable connecting element and preferably has a lever perpendicular to the pivoting surface built into it for mutual change opening position inlet and outlet ports in at least one housing, provided with an insert and interconnected.

A further feature of the invention is that the lever extends through the spherical ball housing to the ganid in the housing, and the rotation plane of the lever is parallel to the plane of the spherical ball housing rotation surface.

At the connecting holes, the spherical ball housings have a clamp-like fitting for connecting to a pipe conduit, and the clamp-like pipe fitting has cuts and one or several threaded holes or holes, and a pin exerting a pressing force is placed in the threaded hole. the walls of the connection opening to the piping. A further feature of the invention consists in that the valve by means eszczone ^j um ^and the two ^{half-d KL d} ki., ^P rzekręconej 90 ° to give e ^j to cut off the outlet opening. Another feature of the invention is that the spherical ball housing with one inlet includes a double opening connecting the spherical cap housing and a one-way flow insert that fits into the branched housing or an insert that allows joint flow and / or split into two. directions.

In the spherical ball casing there is an opening with an inspection window for the inspection of the transported material and / or a temporary pipe stub for the discharge of the transported material.

A characteristic feature of the invention is that any spherical ball housing provided with a curl is attached to any spherical ball housing provided with a groove of the same diameter of the ball. According to another feature of the invention, the hollow passage chamber of the single-flow inserts is cylindrical, and the hollow passage of the double branch-flow inserts has a shape resulting from the penetration of cylinders with rotational axes intersecting in a common plane. According to a further feature of the invention, the inlet joints connecting the spherical ball housings have mounting lugs, and in the mounting lugs they have an opening for receiving the connecting element.

In a preferred embodiment of the valve according to the invention, the housings of the spherical ball and the inserts are made of flexible plastic.

Summary of the invention - a stepless change of the direction of the angle between adjacent pipelines within given angular limits in any direction of the chamber is shown on the basis of the direction changing flow valves according to Fig. 1a.

The valve consists of two mating halves: the groove of the housing cap ^is t balls ^than 45/90 ° Ia ^{and b} to the turned on at the head ^{d k} of the canopy ^leaves ste ^{j 45/90} °. In the ^housings 1a ^{and 2a} there are placed one-handed 45/90 ° 5a inserts tightly adjacent to their internal walls. The housing 1a has a connecting inlet 4a and the housing 2a has a connecting outlet 4b which must be connected via a tubular clamp-like connection to the ends of the pipes. In the position shown, the rotation axes 14a and 14b of the spherical ball housings 1a and 2a coincide. Thus, the transported material flows through the inner chamber 13 without changing direction.

The semicircular shells of the housings 1a and 1b with the inserts arranged therein fit together in common planes sch on the inner rotating surface 13a and on the outer rotating surface 13b. The two halves constituting the valve are completely symmetrical, except for the key joint 8. The inserts 5a are secured against twisting in the spherical ball housing 1a and 2a by a detachable fastening element 9, preferably a threaded pin.

The previously assembled halves are connected via a key connection 8. The groove 8a of the curved spherical ball casing 2a can engage into a groove 8b in the grooved wall of the casing. The housings 1a and 2a are made of a modifiable plastic, so that a mutual adjustment can be made relatively easily. The two halves are mutually twisted in the desired direction on the rotation surfaces 13a and 13b, then they are pressed together by a screw connection through the holes 8c in the fixing lugs in order to avoid further undesirable twisting. The keyway connector 8 is shown in the exploded state in Fig. 1b.

Sockets 11 are provided in both parts of the insert 5a for mounting the crank 10 perpendicular to the rotation surface 13a or 13b in the direction of the rotation axis formed at the intersection of the rotation axes 14a and 14b of the housing 1a and 2a. The lever 10 is shown in Figures 5, 6, 7, 8 and 11. By means of a crank 10, the upper half, containing the insert 5a, can be turned on the rotation surfaces 13a and 13b to the position shown in dotted lines.

In this way, the originally overlapping rotation axes 14a and 14b and hence the hollow passage chambers 6a and the inlet 4a and the outlet 4b will be arranged perpendicular to each other. With this direction-changing valve, a directional change of max. ⁹⁰ °. ^The e ^lk of ^Sc to be zmi.any ^b ra ^Æ in getting my ^{g and a} wound ch ⁰ ° and 90 ° C, depending on the size of the twisting.

FIG. 2 shows another embodiment of the valve with less diversion of direction. Its structure and method of operation are entirely consistent with the description relating to FIG. 1.

In the half section of FIG. 2 is clearly visible the tubular attachment sleeve 7 in the type of clamp. The housings of the spherical ball 1c and 2c, pressed against the ends of the pipes, can be pressed with pins 7d embedded in threaded holes 7c.

In this arrangement, the valve serves to co-flow material and, in the reverse position, with a downward split, it may be used to distribute material.

The directions of the rotation axes 14b and 14c of the double connecting openings 4c located in the distribution housing 3b can be mutually unchanged. The common pivot plane of the two halves is the inner pivot surface 13a through which the two halves can be completely pivoted. The axis of rotation 14d is perpendicular to the surface of rotation 13a.

The difference is the angle between the pivot axes 14b and 14c of the double opening 4c of the upper half, which in this case is ⁶⁰ °. ^G ref ETA ^{and y} m, the upper one ^liter pencil having a housing section ^and that part of ^{60 l} 3a ^and dwuran ^and ESO ^{± KL} smooth ^ę 5e.

After being slipped on, the coupler 7 can be clamped in the manner described above.

The above-mentioned embodiments show that it is not necessary to use gaskets when connecting the valves and the piping to avoid the flow of powdered material to be transported. The connecting openings 4a, 4b and 4c, preferably made of light and flexible plastic, of the spherical ball housing 1a, 1c, 2a, 2c, 3a and 3b are flexibly slipped over the pipes.

If the valve is to be used permanently for shut-off, the insert 5a can be secured with a crank 10. In addition, the valve is suitable for performing periodic shut-off during operation. Then, the insert 5a can be fitted at the most during installation, and then, after removing the detachable fastening element 9, the outlet opening 4b is closed by turning the insert 5a 180 about the axis 14d by means of the lever 10 engaging in the seat 11 of the insert 5a.

Reopening or closing can be performed at any time. For the output of the crank 10, a slot 16 is formed in the housing 2a. Also in this variant, the valve

162 268 serves to change direction, that is, to connect the conduits with different directions.

In these cases, the double connecting holes 4c point downwards. The transport of material flowing into the valve through the inlet openings 4a can be through one or the other connection opening 4c. The upper half is made up of the housing cap to the ^leaf ste ^{j 4 5/90} ° zaopa ^t wo ^b RZONE embodiments of the row ^path and secured ^{in the} fully ^across the insert ^{4 5/90} ° 5a. as the lower ^l i ^<k as 5w ^wit Pri ^{y and} Chap elcza of femur ^{90 b} 3 b in FIG. ^{6, ch e} lc ^{of the} housing ⁶ and 0 ° C in Fig. 7. ^In both wariantac ^yellow hole ^h r ⁴ c is: z ^ ^y-armed enclosing the insert ⁵ and ^45/90 °. contribution ^k E ⁵ and ^mo on a ^b y of ^{C ll of} a ^{p ±} he aid Tone ^and pulling around ^and l ⁰ os ¹ turn 14 wt ^en way that it changes the closed state of the openings 4c to the open state and vice versa.

In the case of the valves used in this way, too, the point is that the halves can pivot one another on the rotation surface 13a, so that also in this case the pipes can be joined in any direction. The housing 1a and the insert 5a fixed therein rotate together when changing direction.

The divider inserts 5f and 5g are shaped in such a way that the upper insert 5f can be moved to any position by twisting the lever 10 about the rotation axis 14d, allowing any separation of the material into the two lower openings 4c. The separation of the material flowing through the inlet 4a is possible in any proportion from 0 to 100%. This means that the valve can function as a shut-off element. Then the entire amount of material flows through the other open opening 4c after closing one of the outlet openings

FIG. 9 shows a top view of the distribution insert 5a positioned in the housing 3a in the plane ΙΧ-ΙΧ of FIG. 8, which coincides with the outer pivot surface 13a. The contours of the lower distribution insert 5g, as well as the outlines formed at the outlet openings 4c, are visible in the plane of the inner rotary surface 13a. A double hollow passage 6b is formed between them. In Fig. 9, only the attached lower distribution insert 5g is shown in a state in which the material separation into the outlets 4c corresponds to a proportion of 50 to 50%.

It should be noted that the material change valves of Figures 6 and 7 are also suitable for material separation. To this end, the insert 5a in the housing 3a or 3b must be brought into the middle position between the double holes 4c in accordance with the desired separation ratio by means of a crank 10.

FIG. 10 shows a variant of the diverter elbow of FIG. 2 with an opening with an inspection window 12 for the transported material. The opening 12 on the folded-up housing 2c can be exposed by turning the insert 5c. The turned position is indicated by a dashed line.

Figure 11 shows a variation of the directional by-pass valve of Figure 1 for sampling. A sampling hole 17 is provided in the spherical ball housing 1a, shown as grooved. The opening 17 in normal operation is closed by the insert 5a, and the material is freely guided between the inlet 4a and the outlet 4b.

During sampling, the insert 5a is turned by means of the lever 10 to close the outlet 4b. at the same time, the material flow is released in the provisional pipe stub 15 seated in the sampling opening 17. Provisional pipe socket 15

162 268 is represented by a dashed line. At the end of sampling, the insert 5a may return to its starting position.

Figures 12-15 show the most important valve types in an axonometric view. In all types, the outer contour of the rotating surface 13b is shown when the two halves are joined.

An important advantage of the valve according to the invention is that valves fulfilling various functions can be plugged from mutually integrated and replaceable elements on the basis of structural modules. The valves are suitable for any spatial arrangement, and the angle between the connected pipes can be any. Neither branch nor spool valves require vertical or almost vertical positioning. These valves can be manufactured economically. The individual components can be mass-produced and are easy to assemble and integrate.

When installing, it is not necessary that the connected pipes are equipped with flanges, as is the case with most of the valves currently used in the milling industry. The dead weight of the valves according to the invention is relatively low, since both the spherical ball housing and the insert therein are made of plastic. So there is no corrosion damage. It is unnecessary to provide a special type of gasket between the valve and the pipe end, since a tight seal between the pipe ends can be achieved by a direct clamp-like connection, and the transported dust material cannot flow out. The valves do not corrode during operation. Only some spare parts require maintenance and repair, as the components are interchangeable. The valve drive can also be remotely controlled, for example by means of an electric motor or pneumatic actuator, the position inside the valve can be switched, or the relative positions of the two valve halves can be changed. Thus, you can easily automate the work, you only need to introduce the lever drive.

The invention may have a wide field of application. It is primarily applicable for milling purposes, for transporting mill products, but it can advantageously be used for other granular or powdered materials. The individual valves can advantageously be used, for example, in the grinding of forage or in the production of fertilizers, for connecting pipes and for diverting, separating and shutting off transported material.
