Embodiment Construction

[0024] Such as figure 1 The shown valve arrangement 1 comprises a valve 2 and a valve attachment 3 fixed to a part 4 of the valve 2 . The valve 2 comprises a pin 5 protruding from the valve 2 , wherein the pin 5 is used for the actuation of the valve 2 . When the valve 2 is a normally open valve, the pin 5 is used to regulate the flow through the valve 2 when it is pressed into the valve 2.

[0025] Actuation of the pin 5 is performed by means of the valve attachment 3 . To this end, the valve attachment 3 may comprise a motor, a thermostat element such as a wax element, or any other kind of device capable of moving the actuating means 6 in a direction parallel to the longitudinal axis of the pin 5 .

[0026] Components of valve attachment 3 such as figure 2 shown. The valve attachment 3 is connected to the part 4 of the valve 2 by means of an adapter 7 which forms an intermediate part between the valve attachment 3 and the valve 2 . The adapter 7 comprises an external t...

Abstract

Described herein is a valve attachment that can be attached to a valve to regulate flow through the valve, the valve attachment comprising: a housing (9); a fixture (10) connected to the housing a body (9) to secure the valve attachment to the valve; and a detection device (6) that detects whether the valve attachment is in a predetermined position relative to the valve, wherein the securing device (10) is movable from a released state to a locked state . This valve attachment should be securely installed in the correct position. For this purpose, the detection device (6) locks the movement of the fixing device (10) in a locked state as long as the valve attachment is not in a predetermined position relative to the valve.

Description

technical field [0001] The present invention relates to a valve attachment capable of being attached to a valve to regulate flow through the valve, the valve attachment comprising: a housing; securing means connected to the housing to secure the accessory to the valve; and detection means for detecting whether the valve attachment is in a predetermined position relative to the valve, wherein the securing means is movable from a released state to a locked state. Background technique [0002] Such a valve attachment is known, for example, from EP 3 156 706 A1. The detection means comprise an indicator which can be seen through an opening in the housing when the valve attachment is in the correct position. [0003] However, when this valve attachment is installed on the valve, the installer must have access to the window to check that the indicator can be seen. In some cases, this has resulted in incorrect installation of the valve attachment on the valve. Contents of the i...
