Definitions
- a butterfly valve with an elastic sleeve to shut off the flow in a piping system is a product well known in the art.
- a model is often produced in a large number of nominal sizes and in large numbers.
- shut-off valve of this type The user expects a shut-off valve of this type to reliably shut off the flow of a conveying medium through high tightness and low leakage rate on the flap disc 20, as well as absolute tightness of the interior against the
- the butterfly valves used in large numbers are generally robust, easy to manufacture and economically cost-effective and are characterized by a very simple design of the sleeve, which is flat and axially symmetrical and has only two cylindrical openings for passage of the valve axis.
- this design has the disadvantage that the cuff moves axially when the valve disc is immersed and that there is no longer any foreseeable geometry at the sealing point.
- the simple design has the disadvantage
- the invention has for its object to provide a butterfly valve with an elastic sleeve, in which the axial deflection of the sleeve around the valve disc is reduced and the sleeve is anchored in the housing.
- volume compensation surprisingly less and thus ensures the sealing effect over a long period of time.
- the preload introduced also makes it more difficult for the cuff to escape into the low-pressure region when it is subjected to the conveying medium, since it offers greater resistance to deformation than a non-preloaded cuff.
- the anchorage of the cuff is ensured even when the valve disc is open and not immersed.
- the development according to claim 5 increases the sealing effect in the region of the valve axis. Since there are two sealing functions at this particularly critical point, namely the shut-off of the pumped medium in front of and behind the valve disc and the sealing of the valve against the environment, the broadening of the collar in this area up to the play-free contact with the side walls of the groove enables the sleeve to be supported and counteracts the evasion of the cuff on the valve axis under pressure. The immersion process in the area of the valve axis is reduced due to the constant contact of the valve disc with the sleeve and the volume compensation is less critical.
- Fig. 2 shows the deformed cuff after immersing the valve disc as a section in longitudinal section.
- the housing (1) of the shut-off valve is lined with a sleeve (2) made of elastic, incompressible material in the area of the flow-through part.
- the cuff (2) has a circumferential collar (3) which is in a circumferential groove (4) comes to lie freely axially. This is achieved in that the width of the collar (3) is smaller than the width of the groove (4) and an intermediate space (5, 5 ') is created, which is ideally evenly distributed over the wide sides.
- the flap disc (6) is shown lifted from the sleeve (2) in a slightly open position.
- Fig. 2 the closed shut-off valve is shown.
- the valve disc (6) dips into the sleeve (2) and displaces part of the elastic material of the sleeve (2). If the displaced material has so far evaded on the surface (7) of the sleeve in the form of warps, the material can now escape into the spaces (5, 5 '). This is indicated by the arrows, which also indicate that the evasive movement of the cuff is blocked under one-sided pressure, since the cuff is supported in the groove and thus limits the freedom of movement.
