Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is an apparatus consisting of a plurality of valve seats assembled as one functional unit, comprising:
one receiving hole for accommodating valve components such as a valve seat and a valve section;
one supply channel and at least one working channel, each of which passes at least partially through each valve casing and each opens into the receiving bore on the one hand and on the other hand. The present invention relates to a valve housing device of the type that opens to the outside via an outlet opening to which a pressure medium source or a working machine as a consumer can be connected.

(Prior Art) In devices that can be operated by hydraulic or pneumatic forces, or devices equipped with components that can be operated by liquid, most of the control mechanisms, especially those consisting of a plurality of valves, are controlled centrally. It is advantageous to place them all in one place.

This arrangement ensures good visibility of the entire installation and good approach characteristics, making it easier to carry out operational control or monitoring tasks as required. You will be able to do things.

However, even when such a control mechanism is centralized, it is desirable to arrange each valve as compactly as possible, so generally,
Increasingly, valves of the same construction style are being assembled as separate construction units. In this case, the valves have the same valve casing for each constituent unit, each valve casing being arranged parallel to one another and the outlet openings of its supply channels being unified in order to reduce the number of supply conduits. connected to two common distribution strips.

In this type of valve casing device, although the pressure medium connection method is simplified in this way, each valve casing made of metal must be manufactured and processed individually, so it is difficult to compare. It becomes expensive.

Moreover, in this type of device not only many machining processes but also multiple tightening and control processes are required.

Further, in assembling the above-mentioned device consisting of a plurality of valve casings, each casing must be separately attached to its corresponding location, which requires an extremely large amount of working time.

Therefore, a considerable amount of time and money must be invested in manufacturing and assembling the above-mentioned known devices.

(Problems to be Solved by the Invention) It is an object of the present invention to improve the valve casing device of the type mentioned at the beginning so that this device can be made into a low-cost, compact structure with a few work processes. The object of the present invention is to enable the device to be manufactured as a single device, and to satisfactorily shorten the time required for assembling or installing the device at the site of use.

(Means for Solving the Problems) In order to solve the above problems, according to the present invention, each valve casing is made of a plastic material, and a plurality of valve casings are formed into a block-shaped integral casing constituent unit. At least several outlet openings in the assembled and working channel are arranged on the same casing side of the casing component, this common casing side having a metal wall extending over the outlet openings arranged thereon. A connecting plate made of the same name is fitted, which is provided with a continuous connecting hole extending coaxially to the respective outlet opening and having a connecting thread.

(Operations and Effects of the Invention) The valve casing device according to the invention can be effectively produced with relatively few work processes.

The casing block is first cast in an advantageous manner, and then the required passages are bored by boring, a suitable configuration of the casting mold being advantageous when producing the casing. At the same time, it becomes possible to form a passage.

In the casing construction unit according to the invention, since this unit is a single part that constitutes a plurality of valve casings, the work process for machining the outer casing walls is significantly reduced.

The assembly work of this casing component unit is also
It takes very little time to assemble the valve casings, in which case the assembly of the valve casings is achieved by essentially assembling a single component.

Nevertheless, individual valve casings
Since it can be arranged in series in parallel, the valve housing arrangement according to the invention has a very compact construction.

In addition, according to the invention, a considerable weight reduction is achieved, and the supply conduit leading to the working machine is repeatedly screwed into the working channel due to the attachment of a metal connecting plate with threaded perforations. It is ensured that breakage or damage to the threads is avoided even when the threads are removed and removed.
These threads are therefore extremely stable and at the same time as robust as known connection threads in metal valve casings.

Advantageous embodiments of the valve casing device according to the invention are disclosed in claims 2 to 16.
The advantages are summarized below.

According to the design according to claim 2, the valve housing arrangement according to the invention can be operated effectively by means of one supply channel leading to all receiving holes, so that only one central supply is required. It is sufficient to provide only the passage outlet opening;
The assembly time required for fitting the pressure medium conduit can therefore be significantly reduced. The insertion of the threaded insert also ensures a stable and reliable connection even though the housing component is made of plastic material.

According to claim 3, it is also possible for the supply channel outlet opening to be provided on the side of the casing on the side of the connecting plate, in which case a separate threaded insert can be dispensed with. . The connection hole is
Advantageously, it is provided integrally in the connecting plate.

According to the embodiment set forth in claim 4, the connection plate and the casing component are irreleasably connected, and a rigid and durable connection between the two is achieved. This embodiment is particularly advantageous in terms of cost, since it is not necessary to provide a sealing member between the two components. On the other hand, if necessary, it is also possible to make a releasable connection in order to exchange the connecting plate.

In order to be able to carry out an assembly taking into account the predetermined dimensions of the pressure medium conduit or working conduit to be connected, several connection plates each having connection holes of different diameters can be selectively connected. The device can be made available. Depending on particular circumstances, it is even possible to carry out the final finishing of the connecting plate directly at the assembly site, provided that the connecting plate is provided with a borehole with the desired thread.

According to the configurations recited in claims 5 and 6, it is possible to connect the casing component and the connection plate directly by means of the sealing member. Therefore, in such an embodiment, the holding function is also fulfilled at the same time, and additional parts such as fixing screws are not required.

The embodiment according to claim 7 is designed as a particularly compact device and, because of its simple geometry, can be manufactured at low cost. Moreover, the connecting part in this case can be mounted in a fixed position on the casing component.

The device of the embodiment as claimed in claim 11 is particularly simple to manufacture and nevertheless:
A durable and reliable connection between the housing component and the connecting plate is guaranteed. This joint can be installed as an insert part in the pouring mold during the manufacturing process of the valve casing device according to the present invention, and after the manufacturing process is finished, it can provide a reliable holding and sealing function. Covered with plastic material.

As the material for the metal connection plate, it is advantageous to use steel, which guarantees high strength at a relatively low cost.

(Embodiments) Next, the present invention will be described in detail with reference to embodiments shown in the accompanying drawings.

1 and 2 show a first embodiment of a housing assembly 6 according to the invention. This casing component unit 6 is assembled from a plurality (four in the embodiment) of valve casings that are integrally formed with each other. Naturally, these valve casings cannot be separated due to their integral construction.

However, in FIG. 1, virtual dividing lines are indicated by dashed lines 7 for clarity, and the casing construction unit 6 is substantially divided into individual valves by these virtual dividing lines 7. Four unit sections 8 that function as casings
It is divided into.

This casing component unit 6 has a block shape, and in this embodiment is formed as a rectangular parallelepiped, so that its cross section has a rectangular or square shape.

A plurality of receiving holes 1 are provided on one side of the casing component unit 6 (its upper surface 9 in the embodiment).
0 is bored, and the longitudinal axis 15 of each receiving hole 10
are oriented at right angles to the flat upper surface 9.

A receiving hole 10 is assigned to each housing unit section 8, each receiving hole 10
are arranged continuously in the longitudinal direction of the casing component unit 6 to form one receiving hole row.
Each receiving hole 10 terminates in the form of a blind hole before reaching the underside 11 of the housing component 6.

It is also possible to form these receiving holes 10 as through holes, but in that case, it is desirable to close the through holes from the unit lower surface 11 side with a plug or the like.

Each receiving bore 10 is used for accommodating valve components not shown, such as a valve seat and a valve section, and has a corresponding internal contour, but not shown. For the sake of brevity, a precise depiction has not been made. However, in the area of the upper surface 9 of the unit a threaded section 12 for screwing the valve component in the receiving bore 10 is shown. In addition, in Figure 1,
Again, for the sake of clarity, the receiving holes inside the housing component are shown only by hatching.

Each receiving hole 10 is in communication with a supply channel 13 connectable to a pressure medium source, not shown.

The valve housing arrangement according to the invention preferably has a single supply channel 13 to which all receiving holes 10 are connected. The supply passage 13 is bored into the casing unit 6 from one end face 14 of the unit and extends in the longitudinal direction of the unit. That is, this supply passage 13 is located in one plane that simultaneously includes all longitudinal axes 15 of each receiving hole 10, and extends across or through each receiving hole 10. hole 10
is placed against. This is the case in the embodiments of FIGS. 1 and 2, and the situation is particularly clearly shown in FIG.

A fluid conduit (not shown) leading to a pressure medium source can be connected to the supply channel outlet opening 16 in the end face 14 of the housing component 6. For this purpose, a metal threaded insert 17 is inserted into the supply channel 13 from the outlet opening 16 and fixed rigidly and non-rotatably, for example by adhesive. A connecting nipple for a fluid conduit can be screwed into the interior. This thread insert 17 has a high thread strength, and even if the connecting nipple is repeatedly screwed on and unscrewed, the thread function will not be impaired.

The supply passage 13 ends before reaching an end face 18 inside the casing unit 6 opposite to the one unit end face 14.

In this case, it is advantageous if the supply channel 13 is drilled as a blind hole, but it is also possible to form it as a through channel and close it on the side of the end face 18, in particular in that case a long It is then possible to produce a composite casing unit of a length and later cut it into individual units of the desired size.

Each receiving hole 10 is connected to at least one (two in this embodiment) working passages 22, 23, which pass through the casing component 6 and are connected to one of the working passages 22, 23. It is open to the outside on the vertical side. According to the invention, at least some outlet openings in these working channels 22, 23 are arranged on the same casing side.

In this case, it is also expedient for all working channels 22, 23 to be guided on the same side of the housing. In FIG. 1, this casing side is adjacent to the unit top surface 9 and is located at right angles to the casing longitudinal side 24.
corresponds to

In this case, it has proven particularly advantageous in terms of manufacturing technology to arrange the working channels 22, 23 in such a way that they extend at right angles to the longitudinal side 24 of the housing and parallel to the end face 14 of the unit. ing.

In addition, in this case, the two working passages 22, 23 leading to the receiving hole 10 of one unit section 8 are parallel to each other in the direction of the longitudinal axis 15 of the receiving hole 10.
and are spaced apart from each other, so that
The working passages 22 and 23 are located above and below each other.

These working channels 22, 23 assigned to the individual receiving holes 10 have the following relative relationship:
Not only the working passage 23 adjacent to the upper surface 9 of the unit, but also the working passage 22 adjacent to the lower surface 11 of the unit.
are each contained in a common plane, preferably parallel to the unit upper side 9 and the unit lower side 11, and these two planes are arranged parallel to each other and at a distance from each other. It is arranged in.

This means that the outlet openings 26 or 27 of the working channels 22 or 23 assigned to the longitudinal casing side 24 form an opening row 28 or 29, respectively, and that these opening rows 2
8, 29 extend in the longitudinal direction of the housing component 6, the respective outlet openings 26 or 27 thereof being arranged one after the other and at a distance from one another.

Outlet opening 2 provided in each unit section 8
6, 27 can be connected to an energy-consuming device, ie a working machine, such as a double-acting working cylinder, for example. The connection expediently takes place via a pressure medium line (not shown), which pressure medium line is connected to each working channel.

The connection in this case is preferably carried out in a releasable manner by screwing. However, according to the invention, the casing component 6 is made of plastic material, which has the disadvantage that the threaded holes formed in the unit are provided with only a low thread strength. This means that if the pressure medium conduit is screwed on and unscrewed, the connecting threads can become worn out and the entire housing component 6 can thus become completely unusable.

Therefore, according to the present invention, in order to fundamentally eliminate such defects, a metal groove extending across the outlet openings 26, 27 is provided on the vertical side surface 24 of the casing in which the outlet openings 26, 27 are formed. It is proposed that a connecting plate 30 be provided, which is provided with a continuous connecting hole 32 extending coaxially to the respective outlet openings 26, 27 and having a connecting thread 31. has been done.

The valve casing device of the invention based on this type of arrangement is easy to manufacture. In this case, therefore, if the housing component is formed as a plastic cast part, the processing steps involved and the weight of the equipment itself are kept to a low level, and the connecting threads nevertheless have a high strength. , the pressure medium conduit can be repeatedly screwed on and unscrewed without damaging the threads.

In this embodiment, the connecting plate 30 is
It extends over the entire length of the housing component 6 in its longitudinal direction. The connecting plate 30 rests with one plate surface 33 on the longitudinal side surface 24 of the casing, and the respective longitudinal axes of the housing component 6 and the connecting plate 30 extend parallel to each other. The width of the connecting plate 30, measured at right angles to its longitudinal direction, ie in the direction of the longitudinal axis 15 of the receiving bore 10, is greater than the distance between two mutually adjacent working channels 22, 23 in one unit section 8. Designed. This connecting plate 30 thus covers all outlet openings 26,27.

As is clear from FIGS. 1 and 2, the connection holes 32 formed in the connection plate 30 are connected to the outlet openings 26, 27 provided in the longitudinal side surface 24 of the casing.
It has an arrangement formation corresponding to the arrangement form of . Two rows of connecting holes 34, 35 are thus formed, which connecting holes 32 correspond to the respective working channels 22, 23 provided in the housing.

Connecting plate 30 to casing component unit 6
In principle, there are two ways to attach the
In other words, there are dissociable methods and non-dissociable methods.

In the non-releasable mounting mode, the connecting plate 30 is fixed, for example adhesively, to the longitudinal side 24 of the housing component 6. According to this adhesive bonding method, the casing component unit 6 and the connecting plate 30 are bonded to each other in an airtight manner, so that there is an advantage that there is no need to insert a sealing member between them.

Furthermore, in a further embodiment of this non-releasable connection method, the connecting plate 30 is so to speak as an insert part, that is to say embedded in the housing material;
It is also possible to configure it as an insert that is at least partially surrounded by this material. The embedding operation in this case is expediently carried out during the manufacture of the casing. In this case, the connecting plate 30 is first inserted into a casting mold and then injection molding is carried out around it.

On the other hand, if the connecting plate 30 and the housing component 6 are connected in a releasable manner, it is possible, for example, if the thread of the pressure medium conduit to be connected does not match the connecting thread 31 of the connecting plate 30. The advantage is that the connecting plate 30 can be quickly replaced in some cases.

In this case, the connecting plate 30 with suitable connecting holes or connecting threads can be installed in the housing component 6 by a simple replacement operation.

In any case, in this releasable coupling method, one or more sealing members 3 are provided between the connecting plate 30 and the casing component unit 6.
6 is preferably inserted, and the work passage 2
In the connection area located between the outlet openings 26, 27 of 2, 23 and the connection hole 32 of the connection plate 30,
The sealing member 36 can prevent the pressure medium passing through each passage from escaping to the outside.

In the embodiment shown in FIGS. 1 and 2, the connecting plate 30 is screwed to the housing component 6, so that the connecting plate 30 is provided with a plurality of mounting holes (not shown). . These mounting holes are aligned with screw holes (not shown) drilled into the casing component 6 from its longitudinal side 24.

The mounting screws, designated 37, pass through the mounting holes and are screwed into the respective screw holes, so that the connecting plate 30 remains tightened relative to the housing component 6.

These fixing screws 37 are designed as internal hexagonal screws which are embedded in the plate surface 38 facing away from the housing component 6. In this case, as shown in FIG. 1, four fixing screws 37 are arranged at the four corners of the plate surface 38, which is preferably rectangular.
It has proven particularly effective to keep the connecting plate 30 fixed.

The mounting holes for these mounting screws 37 are
Providing the connection holes in the same arrangement as the connection hole rows 34 and 35 makes it possible to manufacture the connection plate 30 particularly effectively.

According to this method, the connection hole 32 and the mounting hole for the mounting screw 37 can be formed in one work process.
It becomes possible to drill into the connection plate 30,
It is then only necessary to provide connection threads 31 in these connection holes 32.

In the embodiment shown in FIGS. 1 and 2, a casing component 6 and a connecting plate 3 are shown.
A sealing member 36 is used to seal between the
is configured as a band-shaped seal 41. This band-shaped seal 41 is connected to the outlet openings 26, 27 of the working passages 22, 23 or to the connecting holes 3 of the connecting plate 30.
It has through openings 42 arranged in the same way as 2.

That is, as is clear from FIG. 2, each receiving hole 10 has a working passage 23 and a through opening 4
2 and the connecting hole 32 and, on the other hand, via the working channel 23, the through opening 42 and the connecting hole 32, respectively, to the outside. The working channels 22, 23, the through opening 42 and the connecting hole 32, which cooperate with each other, each extend coaxially.

In order to design the valve casing arrangement according to the invention with compact dimensions, to give it a suitable external shape and to secure the connection plate 30 in place in the casing component 6 in a satisfactory manner, the connection plate 30 is embedded in the casing component unit 6 which has a rectangular parallelepiped shape. The outer plate surface 38 is thus aligned substantially coplanar with the adjacent casing outer surface 43.

For this purpose, a longitudinal groove 44 having a rectangular cross section formed complementary to the outer shape of the connecting plate 30 is bored in the casing component unit 6 from the side of the casing longitudinal side surface 24.

Therefore, this casing component 6 maintains its original rectangular parallelepiped shape even when the connecting plate 30 is attached, and in this case the longitudinal axis 15 of the receiving hole 10 is aligned with respect to the plane of the connecting plate 30. extending in parallel.

Next, a valve casing device according to the invention will be described with reference to another embodiment shown in FIGS. 3 and 4.

The device in this embodiment also has approximately the same shape as the device according to FIGS. 1 and 2, but the manner in which the connecting plate 30 and the casing component unit 6 are releasably connected is slightly different in this case. .

That is, in the embodiment shown in FIGS. 3 and 4, the connecting plate 30 is releasably fitted into the housing component 6. The sealing element 36 itself can advantageously be used as the fitting means.

As shown in FIG. 3, this seal member 36 is
For example, the working passage 23 adjacent to the upper surface 9 of the unit
and the connecting hole 32 belonging thereto. This sealing member 36 consists of two sealing connecting tube pieces 45, 4 of the same size that are arranged coaxially with each other.
6, and these connecting tube pieces are constructed integrally with each other in the form of a substantially hollow cylinder.

These sealing connections 45 , 46 have one consistent, common, and coaxial flow channel 47 , with one sealing connection 45 leading to the working channel from the side of the outlet opening 27 . 23, while the other seal connecting tube piece 46 is inserted into the connecting hole 3 from the plate surface 48 side of the connecting plate 30.
It is inserted into 2. Connection pipe piece 45 for each seal,
46 are each made of a rubber elastic material that exhibits a sealing function.

It is expedient if the working channel 23 and the connecting hole 32 in the insertion region of the sealing connecting tubes 45, 46 are provided with plug-in expansions 49. According to this measure, the sealing connecting tube pieces 45 and 46 are
While it can have a larger outer diameter than the passage or borehole to which it is to be connected, the flow passage 47 can have a diameter that matches the same diameter in the working passage 23 and the connecting hole 32, and thus the pressure medium An unhindered flow movement is guaranteed.

Each seal connecting tube piece 45, 46 has a ring-shaped holding protrusion 5 along its outer circumferential surface.
0 is set. These holding protrusions 50 are
They can be fitted into retaining grooves 51 which are formed in complementary shapes on the inner peripheral surfaces of the insertion expansion portions 49 in the working passages 22, 23 and the connecting holes 32, respectively.

In this case, these holding protrusions 5 that correspond to each other
0 and the holding groove 51 are the connecting tube pieces 45, 4 for sealing.
6 is completely inserted into the insertion expansion part 49,
They are arranged in such a way that they are working together for the first time.

Incidentally, since the working passage and the connecting hole which form a pair adjacent to each other are connected to each other via the sealing member 36 described in relation to FIG. 3, the flow path can be reliably sealed. At the same time, the casing component 6 and the connecting plate 3
A stable fixed holding state between 0 and 0 is also guaranteed,
Even if the pressure load in the individual flow passages increases, the connecting plate 30 will not be separated from the casing component 6, and there will be a stable and reliable connection between the retaining projections 50 and the retaining grooves 51. A form-locking connection is maintained.

In order to streamline the installation of the sealing elements 36, it is advantageous to connect a plurality of sealing parts together, as shown in FIG.

In other words, the individual sealing connecting pieces 45, 46
is the seal strip 5 which can also be seen from Figure 3.
Both sides of 2 are integrally molded so as to coaxially face each other. The sealing strip 52 in this case is
It has a through opening 53 arranged coaxially with respect to the flow passage 47 .

The sealing strips 52 extend along the longitudinal direction of the connecting hole rows 34, 35, and the pairs of sealing connecting tubes located opposite each other are connected to each other in the individual connecting holes 32 of the rows 34, 35. They are successively arranged in the longitudinal direction of the sealing strips 52 at a distance equal to the spacing.

In this case, it should be noted that if a longitudinal groove is bored in the plate surface 48 which is configured complementary to the sealing strip 52, the sealing strip 52 will occupy a recessed position in the connecting plate 30 and will not be able to penetrate into the plate surface. 48 is particularly advantageous since it is ensured that it rests on the side of the casing component 6 facing it.

It is clear that the sealing member 36 may be combined with differently configured devices. In this embodiment, the two sealing strips 52 are integrally connected to each other, so that all the necessary sealing connections are not shown in the drawings.
are integrally connected to each other.

FIG. 5 shows a further embodiment of the valve casing arrangement according to the invention. The supply passage 13 in this embodiment has its outlet opening 16
However, the outlet openings 26, 27 of the working passages 22, 23
It is arranged so as to pass through the inside of the casing in such a manner that it is disposed on the side of the casing longitudinal side 24 having a diameter.

In this case, the outlet opening 16 of the supply channel 13 also
It is covered by a connecting plate 30 , which is provided with another consistent connecting hole 54 , which is arranged coaxially with respect to the outlet opening 16 of the supply channel 13 .

In this embodiment, the connecting hole 54 has a connecting thread, so that there is no need to arrange a separate threaded insert in the outlet opening 16. The sealing between the connecting hole 54 and the supply passage 13 in this case is performed in such a way that the working passages 22, 23 and the connecting hole 32 are connected.

Depending on the intended use of the valve housing arrangement according to the invention, it is also possible to arrange outlet openings on several housing sides of the housing component 6. In that case, one connecting plate 30 is assigned to each side of the casing, although this is not shown.

This measure is particularly effective if each unit section 8 is constructed as a multi-way control valve with a number of supply and discharge conduits.

In the embodiment shown in FIG. 1, the individual unit sections 8 can form, in particular, a four-port, two-position directional control valve.

If the exhaust passage 55 is not formed as part of the valve component to be inserted into the receiving hole 11, each receiving hole 11 is connected to this exhaust passage 55.
Needless to say, it can be connected to Each exhaust passage 55 can be connected to a separate or common sound insulation device, or to multiple branching members that direct the exhaust to a desired location.

In the valve casing device according to the invention, the shape of the casing valve component unit 6 is not limited to a rectangular parallelepiped structure; on the contrary, it is possible to construct the unit in various different shapes, for example by using appropriate grooves. The connecting plate can also be fixed by drilling later.
However, the illustrated embodiment has proven to be particularly advantageous in that it has a very compact design.

The valve housing arrangement according to the invention is practically designed as one component.
This unit consists of a plurality (four in the exemplary embodiment) of approximately rectangular or cubic valve casings connected to one another and arranged in parallel.

A particular advantage of the invention is that by producing a single component, it is possible to provide virtually multiple valve casings.

In other words, the present invention significantly reduces the great effort and expense that would otherwise be required if these valve casings were manufactured individually.

By manufacturing this component from plastic material, each channel located inside it can follow any course that suits the particular conditions.

The housing component according to the invention can be manufactured as a cast part. in this case,
Since each passage, each opening, and each perforation are already formed in consideration of the conditions during the pouring process, subsequent machining processes can be minimized.

Furthermore, the valve casing device according to the present invention,
There is no need to install multiple valve casings individually at the point of use.
It is done extremely quickly.

Individual connection holes 3 provided in the connection plate 30
2 or the connecting threads 31 can each have different diameters or thread shapes, so that the pressure medium conduit can be attached to the housing component 6 via connecting pieces of different dimensions. It is possible.

According to an advantageous embodiment of the invention, which is not shown, it is possible for each working channel to be designed in duplicate. In that case, one of each of these double working passages opens at one casing side,
The other working channel opens on the other side of the casing.

In this case, each housing side is assigned a connecting plate with a connecting pin, and the connecting holes in both connecting plates each have a different diameter or thread type, whereas The connecting holes in each individual plate have mutually equal diameters or thread types.

Depending on whether one or the other of these dual connection holes is used, the corresponding other or one connection hole is closed by a plug or similar member.

That is, in order to perform rational manufacturing, the casing component unit of the present invention has different standard screws (for example, NPT screws and BSP screws, i.e.,
Tapered threads and standard threads) can be provided. Therefore, there is no need to spend time and effort in manufacturing two valve sides, and since each casing component unit can be connected using two types of standard threads, there is no need to use different types of threads when delivering the product. There is no confusion between the individual valve casings.

In addition, such confusion of valve casings is caused by
Storing valves can also cause serious problems.
