    摘要： A water hammer arrestor and drain trap primer valve includes a hollow pipe having a closed end, a discharging end, an inlet, an outlet port connected to the discharging end and attachable to plumbing tubing, an inlet port connected to the inlet and attachable t plumbing tubing and an insert plug within the pipe positioned at the discharging end and at the inlet. The insert plug is substantiall tubular with opposing flats, and has a longitudinal cylindrical bore and a latitudinal threaded through bore.

    摘要： The invention has its object to radically resolve an untapped technical issue in a non-water hammering check valve device, in which a valve disc, a valve seat and a surrounding flow passage are configured such that the valve disc is substantially seated on the valve seat at the time when input to a pump is shut off and a discharge flow in the flow passage loses inertia to stop, and to provide a reasonable non-water hammering check valve device of a simple and clear construction which suffers a small resistance loss of a valve at the time of a predetermined maximum flow rate, can readily accommodate an abrupt change in a flow state without delay in valve closing operation and provides a uniform and close seating on the valve seat at the time of valve seating to prevent water hammering. In the non-water hammering check valve device, a valve disc (4) is connected to an arm portion (5) through a valve disc support shaft (6) with a required freedom of swinging, and the arm portion (5) is connected to a valve body (1) through an arm support shaft (7). At the time of valve opening, the valve disc (4) is caused by an additional acting force, which turns the valve disc (4) about the valve disc support shaft (6), to be floatingly supported in the flow passage while an upstream end (4a) of the valve disc and an upstream end (5a) of the arm portion preferentially abut against each other all the time. At the time of valve closing, a downstream end (4b) of the valve disc preferentially abuts against a valve seat (3), and in a subsequent valve seating stroke, the entire surface of the valve disc (4) comes into uniform and close contact with the valve seat (3) to prevent water hammering caused by counterflow.

    摘要： A shock absorber in a liquid conduit (4). The shock absorber comprises a closed liquid tank (10), which is partly filled with gas and has a joint means (11) connected to the conduit (4). Via the joint means, liquid can flow to and from the tank (10) for compressing and decompressing the gas. The joint means (11) comprises a check valve means which, in its forward direction, permits a substantially free liquid flow from the conduit (4) to the tank and, in its rearward direction, permits throttled liquid flow from the tank to the conduit.

    摘要： A boiler includes a burner (11) that heats water circulated by a pump (13) and transiting in a primary exchanger (12). Switching means switch water circulation on command between an external heating circuit (15) and an internal sanitary hot water production circuit (16). A bypass circuit is arranged parallel to the external heating circuit and includes a bypass valve (19) that when necessary opens to allow normal bypass flow. The bypass circuit also includes a second valve (25) allowing passage in the bypass circuit of a flow directed oppositely to the normal bypass flow. This was found to avoid the 'water hammer' due to switching between the heating circuit and the sanitary water production circuit.
