DE2505751A1 - Metal control valve for pipework - has central spindle with lever turning curved vanes fitted between closer plates - Google Patents

Abstract

The design is for filtration circuits on swimming pools. The valve (16) is on the lower side (15) of the housing (14) with a central connecting pipe (9). The valve closing spindle (30) fits via a guide (31) in an extension on the lower part of the housing and is operated by a rotating action effected by a lever (1). The main part of the housing has a connection pipe at each end (4, 5) and the closing gate itself has a curved vane (21) that enables two of the parts to be connected together excluding the third and a U shaped vane with the open end pointing outwards. This shuts off one part completely while the curved vane closes another part. In this position the valve is closed.

Pipeline switches of metal, in particular for filter systems for swimming pools

The invention relates to a pipe switch of metal, especially for FiIteranlagen of Sehwimmbecken, a plurality of which opens into a cylindrical valve housing, switchable by a tap member has .Anschlußleitungen _o

In the case of the pipeline switches designed as a cock To achieve a good seal, a conical valve body and a conical valve plug are generally provided, so that you press the plug against the conical surfaces of the valve body and thus ensure the tightness of the valve can »However, there is a risk of seizing with taps made of metal such as bronze. Such taps can also become leaky due to oxidation or contamination Kükenanpreßdruckes to be applied often very stiff.

It is also known that roosters and their chicks are cylindrical auszubildeno These taps are generally smooth, but problematic in terms of sealing. By Precise fit or by using special sealing linings one can counteract the sealing problems here as well <> However, if these taps lose their seal in use, As a rule, all tap connections are affected by this, or "some connection becomes leaky" with many in practical applications it is often uncritical whether the tap leaks something with regard to one or the other connection, as long as the maintenance of a perfect seal was guaranteed for only one of the connections However, the latter condition cannot be fulfilled with the known cylindrical taps

The invention is based on the object of a smooth-running To create pipeline switch made of metal, in which the risk of seizure is eliminated and the sealing state of a specific connection regardless of the sealing condition the remaining connections is.

Starting from a pipeline switch of the type mentioned, this is achieved according to the invention in that a valve with a downwardly directed connection is attached to the underside of the tap housing, the valve closing part of which via an Eulissenführimg -with a lower one. Terlängerting of the

Hahnkükens is coupled and! depending on the turning position the cock plug assumes its open and 'closed position, and that the plug with an axial passage for connection the connecting lines opening into the tap housing with the Valve interior is provided.

According to the invention, a pipe switch combined with a tap and a valve is provided, in which the valve is controlled at the same time by actuating the tap. The sealing state of the valve is in this case completely independent from the sealing state of the faucet-side terminals, so that the terms of sealing particularly critical finish are applied to the valve output k a nn and good sealing performance of operating as Pretty age valve can be utilized "The pipe switch according to the invention is characterized is characterized by a very smooth adjustability and, in addition to being operated by hand, is also particularly suitable for motorized adjustment.

According to further features of the invention it can be provided that the tap housing and the valve housing are attached to each other facing sides are open and that the chick has a HaTmgehäuseininnenraum has a disc that shuts off the valve housing interior and is penetrated by the axial plug passage "

609834/0552

According to a preferred embodiment of the invention has the tap housing has four connections distributed over its circumference and the link guide for the valve closing part runs in such a way that when the axial valve plug passage is aligned on three of these connections, the valve is open »In addition to this axial passage, the cock plug according to the invention with two passages for mutual connection of the Connections provided on the tap housing can be provided the se ± LS masters various functions that are usually required to control the filter systems in swimming pools as will be explained in more detail using the drawing ο

In a further development of the invention it can also be provided that the valve closing part consists of an axially displaceable in the Valve housing mounted, the link guide having control part and from a mounted in the control part, there is a valve disk loaded by a closing pressure spring, which is a fraction of the total valve opening movement in the Control part can be moved · This measure is on the one hand a reliable valve closing pressure is achieved, on the other hand the link guide largely depends on the valve closing pressure, or where its reaction force is relieved, which contributes to the easy turning of the plug.

FIGS. 2 "to 5 illustrate the structure of the for this Switching tasks of usable pipe switch 2 «.

The pipe switch has a cylindrical tap housing 14 with the connections 4, 5, 6, 7. On the valve housing 14, which is open on its underside 15, there is a funnel-shaped bottom Screwed on valve housing 16, which has connection 9 ο In the tap housing 14 there is a lever 1 rotatable cock plug 17 arranged, which consists of an upper Disk 18 and a lower disk 19 is made, which over two axial partitions 2G, 21 are connected to one another, their ends each to the inner wall of the tap housing adjoin · Furthermore, the two disks 18, 19 have a vertical, extending a little along the circumference of the chick Wall 22 connected to each other. While the disk 18 is closed, the disk 19 is in that of the wall 21 enclosed edge area with a through opening 23, which leads to the interior space 24 of the valve housing 16. As can be seen from Fig. 3, has the cock plug on each side of the wall 20 a passage 25 »26, with which connections between ports 4, 5 »6, 7 of the Valve body can be manufactured

The cock plug 17 is on its underside with a coaxial tubular extension 27 is provided. In a radial hole in the Jacket of this pipe extension 27 is a screw 28 incorporated

screws, whose inwardly protruding end forms a sliding block 29, which is in the groove-shaped, on the valve closing part 30 provided link guide 31 engages. This valve closing part 30 consists of a bush-shaped control part 32 and from a valve disk 33 guided therein. The control part 32 has a flange 34 at the bottom, which with two diametrically opposite through bores 35 »36 on pins 38 which are fastened to the valve housing 16 are axially displaceable but non-rotatable · In the assembled state, the lower one is seated Washer 19 of the cock plug 17 on the upper edge of the Valve housing 16 attached cam 39 axially immovable on · When turning the valve plug moves the attached to this Kulissensteim 29 from the groove-shaped link guide 31. So long if the sliding block 29 is in the high-lying part of the sliding block guide on the left in FIG. 4, the remains Valve closing part 30 in its lower closed position; runs the sliding block 29, on the other hand, enters the deep part of the sliding path on the right in FIG. 4, becomes the valve closing part 30 raised to its open position

As can be seen from Fig. 5, the one with a rearward Guide rod 40 provided valve plate 33 by a valve closing pressure spring 41 loaded, which is supported on a lower inner shoulder 42 of the bush-shaped control part 32, in the guide rod 40 is a stop at the top
