Device for connecting an apparatus to a liquid line

The invention relates to a device for connecting an apparatus to a liquid line, and in particular to one Device for shunting or bypass connection.

Such devices are used when the water available in a pipeline network requires treatment is to be subjected to an apparatus which is connected in a branch or in a shunt to the water pipe is, for example, a water heater or a water softener.

If the connection device is used in the example of a water softener is in the operating position, a calcareous j i.e. hard water flows through an ion exchange resin and reaches the connection point softened. In the bypass position, the hard water is routed directly to the point of use; the softener is then outside the line. This case occurs, for example, when repair or maintenance work is being carried out on the softener or if you need water for irrigation at a tap located downstream of the apparatus.

609848/0579

A completely softened water, i.e. one from Calciurasalzon free water, is corrosive and corrosive in steel pipelines is unsuitable as drinking water. The content of calcium salts is determined by the degree of hardness of lime or T.H. value; hard Water has a T.H. value roughly in the range between 25 and 35.

The object of the invention is to provide a connection device that has a controllable mixture of hard water and softened water allows. This object is achieved according to the invention solved by a device for connecting an apparatus to a line, with an automatic valve and a manually operable hollow valve carried by a hollow valve carrier which is rotatable by means of a Handwheel is longitudinally movable, the valve carrier with openings is provided and wherein the drive shaft of the valve carrier is hollow and has a shaft in its interior, the position of which can be changed to control the flow of water through the openings.

The invention is illustrated below using an exemplary embodiment explained in more detail, which is shown in the drawing. Show it:

Fig. 1 in a longitudinal section a connecting device in the bypass position, and

2 shows the same device in the operating position.

From the drawing it can be seen that the connecting device has a housing 1, which consists for example of brass chill casting; A line which supplies hard water opens into the housing 1 upstream at 2, and the line which supplies softened water is connected downstream at 5; at 3 or 4 the lines are connected that lead to your softener and back from it. The housing 1 has an inner partition 6 and a valve seat 7 _f which is intended to receive a seal 9 of a valve 8 in order to separate the softener in the bypass position. The inner partition wall 6 carries a toroidal seal 10 in a groove. This seal ensures a tight seal when it receives the cylindrical outer surface of the valve 8 in the operating position (FIG. 2).

The housing 1 also has a seat 11 close to the return line of the softener on; the seat 11 is intended to accommodate a seal 13 of an automatic valve 12, which is under the action of a spring 14.

The housing 1 receives a threaded hollow head 15 in which an actuating shaft 16 is located, which in FIG its upper part is firmly connected to a handwheel 17. The shaft 16 is in its axial position relative to the head 15 held by a circular projection 18 of the shaft and, for example, a snap ring 19, with seals between the head 15 and the shaft 16 are provided.

The hollow head 15 has a cavity, for example hexagonal, which is intended to accommodate a valve carrier 20, the outer profile of which is also hexagonal and which is in,

Inside has an internal thread which cooperates with the thread on the lower part 21 of the actuating shaft 16. Through this you can move the valve carrier 20 upwards or downwards by turning the handwheel 17 without it being able to rotate. The valve carrier is in the bypass position (Fig. 1) in its lower position and the valve 8 is seated on its valve seat 7; the water softener line is closed; the automatic valve 12 is also closed under the action of spring 14, and the hard water passes through it Housing 1 directly to the consumer line 5. If you turn the handwheel until the valve support 20 is in its other Extreme position is (Fig. 2), the valve 8 closes the inner partition 6 on the ring seal 10, whereby the line 3, which leads to the softener, is open; the pressure of the water in line 4, which returns from the softener, opens the automatic valve 12 and compresses the spring 14, the softened water then being passed to the consumer line 5 will.

To obtain a predetermined mixture of the hard water with the softened water To ensure water, i.e. to control the T.H. value of the consumption water, the valve carrier 20, the is hollow, 8 openings 26 above the valve. The actuating shaft 16 is hollow and provided with an internal thread. An inner one Shank 23 is connected to a screw head 27 which cooperates with the internal thread of shaft 16. The shaft 23 has in its upper part a collar 25 which can be brought into contact with the lower part 21 of the shaft 16; the Shank 23 has a groove with a toroidal shape on its lower part Gasket 24, through which a seal with the interior

609848/0579

of the valve 8 achieved v / can be grounded.

The shaft 23 and the screw head 27 are half on the left in their uppermost position and half on the right in their lowest position shown in the drawing, with the corresponding reference numerals on the right with an index line are provided. It can be seen that in the bypass position (FIG. 1) the ring seal 24 (24 ') always acts as a seal the interior of the valve 8 and the separation of the line 3 ensures.

In the operating position (FIG. 2) the hard water can penetrate into the space 22 between the valve 8 and the shaft 23 and pass through openings 26 to mix with the softened water. In the extreme lower position 23 'of the shaft, the collar 25' is supported above the Valve 8 and closes the space 22, so that the flow of hard water to the openings 26 is interrupted. The consumption water is then only the softened water, whose T.H. value is equal to 0. In the extreme upper position 23 of the shaft, the proportion of hard water reaches a maximum value and the consumption water has a T.H. value of, for example, 12. Between these two extreme values, intermediate values can be set by adjusting the Screw head 27 after removing a screw 28, which serves as protection and for fastening the handwheel.

The connection device according to the invention makes it possible to supply or disconnect by a single operational measure

to separate a water softener, whereby a simple control of the T.K. value of the consumption water is made possible by mixing the softened water with your hard water in an adjustable mixing ratio.
