Problems solved by technology

[0007] In order to be operable, the valve body includes a large number of separate parts (not all mentioned here), which increases the cost and complexity of manufacturing and installation
Although the degree of sealing obtained by the valve body is sufficient for the above-mentioned purposes, a truly reliable and completely leak-free closure cannot be obtained with the past form of the deformable gasket resting on the annular surface of the valve housing.

Embodiment Construction

[0019] figure 1 Illustrated in the example is a T-shaped quick-connect device 1, and the main connection body of the medium is between the quick-connect 2 and the connecting branch pipe 3 arranged at a right angle. Auxiliary branch pipe 4 is an extension of connection branch pipe 3 and accommodates check valve 5, as figure 1 The exploded view shows each part in its pre-assembled or installed state. Also, refer to figure 2 longitudinal section view. For the quick connect device 1, figure 2 Only the auxiliary branch 4 is shown with the non-return valve 5 therein. The auxiliary branch pipe 4 constitutes a hollow cylindrical casing 4 with evenly spaced longitudinal grooves 6 on the inner wall of the cylindrical casing 4 (see also image 3 ), and it includes an inwardly facing annular surface 7, the annular surface 7 is located in the quick connection device ( figure 2 Not shown in ) part of the transition.

Abstract

The quick-coupling unit (1) has a no-return valve (5) in a bypass branch, with a valve body (10) built into the housing in one piece, with a valve cone (11) and conical seat (16) at the open end of the bypass. The bypass branch also serves as the valve housing for the no-return valve. The no-return valve may be made of plastic.

Description

technical field [0001] The invention relates to a quick connection device for a transfer pipeline of a flowable or pourable medium, which includes an integrated valve body for controlling the pressure of the medium or opening the medium transmission pipeline, wherein the check valve is installed in the auxiliary On the branch pipe, the branch pipe is branched from the main line of the quick connection device, the opening leads to the outside, and its valve body can be moved from its position preventing the passage of the medium against a restoring force to the externally accessible valve stem so that The location where the media passes through. Background technique [0002] European patent application EP 1 223 392 A1 describes a valve body for filling cooling lines of an air-conditioning system with coolant. The valve housing of this valve body has a connecting piece, by means of which the valve body can be swiveled to one side in the area of ​​the filling opening on the co...
