DD239457A1 - DEVICE FOR THE AUTOMATIC VENTILATION OF MEDIA SYSTEMS - Google Patents

Abstract

The device according to the invention is preferably used for venting heating systems consisting of a boiler, a pipe system and radiators. The aim of the invention is that with the use of this device, an automatic venting of heating systems or other liquid media services allows and thus an improvement of the heating power is achieved. According to the invention, this object is achieved by attaching the automatic deflation control to the upper end plug of the heater. This device consists of a tap, pressure cylinder with screw cap and float with lever mechanism. Through the liquid medium of the float is moved. In the upper position the Ausstroemoeffnung is closed. Falling fluid level opens the Ausstroemoeffnung, and the air escapes when filling until the max. Filling level.

Description

that it is held by own weight and by spring action 5 in the lower position and the opening 11 is for discharging the air-free.

Is in a filling process of the heating system, the air completely on the way

- bent piece of pipe

- Tap

- Pressure cylinder between float and wall

- Outflow opening escaped,

so the inflowing heating medium pushes the float in the upper position and closes the opening 11th

This is the automatic effect.

Falling state of the heating medium 6 leads to the release of the opening. Turning the printing cylinder around the vertical axis (90 °) turns off the automatic.

In the "Automatic off" operating state, maintenance of the automatic mechanism can take place after removal of the cover.

Claims (3)

-1- Z39 457 claims: 1. A device for automatic venting of media systems, preferably for central heating systems, characterized in that the device in the upper end plug (2) of a radiator body (3) mounted from a pressure cylinder (13), a cover (1) with a via a lever system with eccentric action (10) connected to float (12) and from a in the cock (14) opening into the space (4) of the radiator above the upper nipple edge (8) reaching curved pipe section (15). 2. Device according to item 1, characterized in that the automatic by a rotation of the printing cylinder (13) is ineffective by 90 °. 3. Device according to item 1 and 2, characterized in that in the operating state "automatic off" disassembly of the automatic part by removal of the cover (1) for maintenance is possible. For this 1 page drawing Field of application of the invention The device according to the invention is preferably used for venting heating systems, consisting of boiler, tubular composite systems and the associated radiator body. This device can also be provided for other systems which are filled with liquid media and for the function of which a vent is required. Characteristic of the known technical solutions Usually, a vent tap is attached to the end of a radiator body for the ventilation of the heating systems and operated manually by the operator. This is usually done once at the beginning of the heating period when heating medium is filled. Apart from occasional checks, there is no constant venting of the heating system, partly due to the stiffness of the taps. This is associated with the formation of air cushions, a poorer circulation of the heating medium and an associated significant reduction in the heating power of the radiator body. The heat output is not achieved. A vent valve for radiators is known, consisting of valve body and screw (OS DE 3308255). In this case, the conical valve body tip, pressed by the buoyancy of the heating medium in the vent hole seals the medium space. In this case, no absolute seal is achieved (tilting of the valve body) and drops form at the vent hole. Object of the invention The object of the invention is that with the use of this device allows automatic venting of heating systems or other liquid media lines and thus an increase in the heating surface is achieved, which leads to a more effective use of radiator radiator surfaces. The respective room is, more heat supplied, and the heating takes place in a shorter time. Explanation of the essence of the invention According to the invention, this object is achieved by providing the upper end plug of a radiator with a thread for receiving the automatic venting, preferably ¹ A ", in which the device consisting of cock, pressure cylinder and screw cap with float and lever mechanism is inserted Filling operation is inhibited until the system reaches a level of 60 to 80%, and the automatic system is activated by a 90 ° rotation of the pressure cylinder, with the air flowing out of the heating system escaping through a curved valve in the space above the system Through the vent opening to the outside, through the vent opening to the outside, the weight of the float keeps the outflow opening open, a compression spring is used to secure the function when closing Radiator so high that penetrates through the curved tube heating medium into the pressure cylinder, the float moves to the upper end position, and via a lever system with an eccentric effect is carried out closing the outflow opening in the lid. If the water level in the pressure cylinder falls due to inflowing air, then the sinking float again releases the discharge opening in the lid, and the accumulated air escapes until the opening is shut off by the float moving into the upper end position, moved by the inflowing heating medium. embodiment The invention will be explained in more detail below using an exemplary embodiment. The device for automatic venting is shown in FIG. It consists of the projecting into the air space bent pipe section 15, which opens into a tap. In the pressure cylinder 13 mounted on the tap 14, a float 12 is arranged on an eccentric lever system 10, held by a lid 1 provided with sealing ring 3,
