Abstract
Description
Main claim: Screw-down valve with an integrated venting valve, characterized in that it functions as a water passage regulator, but at the same time allows water and air to escape outside the delivery line up to a defined pressure.Description:The following is referred to as a screw-down valve with a venting valve (NmE), which is connected to the pump housing at a suspension force syringe. It regulates the water flow rate. The pump normally has two outlets, each of which has a screw-down valve.The NmE has an input, a main output and a sub-output, in contrast to previous screw down valves having an input and an output.The NmE sits on an outlet of the pump, preferably the outlet used for water delivery.The invention consists in that the auxiliary outlet of the NmE is used to discharge the water or air in the pump casing up to a certain pressure or switching point parallel to the main outlet and both systems together in a single screw-down valve.The principle is referred to as rapid venting and is used to quickly discharge the air present in the pump housing, which influences the water delivery. As soon as the water pressure or the switching point is present, the valve is closed. FIG. 1 shows a version with a spring-loaded poppet valve which closes from a certain water pressure. Instead of the spring-loaded valve, a pneumatic, hydraulic or electrical mechanism could also close the valve.There are quick release systems which are individually connected to the second outlet of the pump. The disadvantage of these systems is that there is still an air cushion at the first outlet, which is not discharged.The combination of the screw down valve at the first outlet of the pump with the integrated venting valve achieves a more effective venting.List of reference characters1 Pump housing 2 Screw-down valve at outlet 2 3 Screw-down valve with integrated venting system at outlet 1 4 Main outlet NmE 5 Secondary outlet NmE
Claims
A screwdown valve with an integrated, parallel-operated venting system, characterised in that both systems are combined in a screwdown valve.NmE according to claim 1, characterised in that the venting system can be set to a fixed pressure value or switching point (e.g. drive speed) until it closes.NmE, characterized in that the venting system allows a bypass stream to escape parallel to the main water stream.
