VALVE SYSTEM

Abstract

The invention relates to a valve system, in particular for controlling the liquid flow in a plant for central heating. The system may comprise one or more valve housings with at least two associated distinct inserts having different flow characteristics. The inserts comprise two types of means with regulable openings that serve as inlet and outlet, respectively, said means being provided with means for regulating the liquid flow, the differential pressure over the openings of that first means being changeable, whereby the area of the openings of the other means is changed to the effect that the differential pressure is regulated. The inserts are furthermore provided with means for the applied change in area by means of an activator that comprises an end which is exposed to the surroundings. A programmable regulator unit provided with motor can be coupled to the end of an activator on the insert. The regulator unit is programmed such that it is capable of regulating the activator in response to the flow characteristics of the insert and hence the liquid flow through the valve housing coupled to the control unit.

Description

Concerning European patent 2 612 209 (DE 60 2011 051 547), the 5th Senat (Non-Keith Sat) of the federalized jurisdiction has recognized for rights on the basis of the verbal negotiation of January 31, 2024.I. The European patent EP 2 612 209 is not explained for any details in the scope of claim 1 with effect for the Höheits Art of Federal Republic of Germany.

Claims

The components of the non-rigid components are not of any particular typeA valve system according to claim 1, characterized in that the system comprises means for measuring the position of the activator (17) and a data processing unit for estimating the flow of liquid through the valve on the basis of the position of the activator (17).Valve system according to claim 1 or 2, characterized in that the programmable controller unit (6) is capable of influencing the activator (17) at several different speeds depending on the size of the distance to be covered.Valve system according to any one of claims 1 to 3, characterised in that the system comprises means for measuring the energy consumption in the engine (20) and a data processing unit designed to estimate the force or the moment at which the activator (17) is influenced.Valve system according to claim 4, characterized in that the programmable controller unit (6) estimates the torque on the basis of the energy consumption in the engine (20).Valve system according to claim 5, characterized in that the system comprises a switch causing the stopping of the motor (20) when it is estimated that the force or moment in the activator (17) exceeds a maximum value stored in the memory of the programmable controller unit (6).A valve system according to claims 1 to 5, characterized in that the system comprises means for measuring the temperature in the programmable controller unit; and in that the system comprises a switch which turns off when the temperature is outside a range stored in the memory of the programmable controller unit (6).Valve system according to claims 1 to 7, characterized in that a part of the memory of the programmable controller unit (6) is stored in an electrically independent unit, so that data is stored and accumulated.Valve system according to claims 1 to 8, characterized in that it comprises an interface with the effect that the programmable controller unit (6) can be programmed via this.Valve system according to claims 1 to 9, characterized in that the programmable controller unit (6) comprises an interface in the form of an RFID system or an infrared system, wherein a mark arranged in connection with an insert or a valve body (18) is detected by an antenna part arranged in connection with the programmable controller unit (6), whereby the programmable controller unit (6) is automatically adapted to the connected insert.Valve system according to claims 1 to 10, characterized in that the valve body (18) comprises a connecting part (51) with associated identification means; and in that the programmable controller unit (6) comprises means capable of reading the identification means, whereby the programmable controller unit (6) is automatically adapted to the connected insert.Valve system according to claim 11, characterized in that the programmable controller unit (6) and the valve body (18) can be connected to each other via a so-called snap-fit coupling; and that the identification takes place by mechanical detection of when parts are connected or have been connected to each other.
