Abstract: A synchronous switch valve core with a voltage stabilizing function, comprising: a valve core housing (1), a valve core base (2), a flow regulating module, and a balancing hydraulic module. The flow regulating module is capable of cutting off a cold/hot water path before water enters a pressure balancing module, thus preventing high-temperature water from immersing the valve core, preventing the building of lime scale, protecting the valve core, and extending the service life; moreover, water flow can enter the pressure balancing module only after flowing through the flow regulating module, thus preventing the channeling of hot and cold, and obviating the need to install a check valve at a water intake elbow.

Abstract: A pressure control valve for gases and/or liquids comprising a first sealing body and a second sealing body for opening and closing a first flow path and a second flow path, respectively. The first and the second sealing bodies can be installed in an inflow for gases and/or liquids in order to define the first and the second flow paths therein. The first sealing body is guided in an axially movable fashion. The second sealing body is guided in an axially movable fashion within the first sealing body. The first sealing body is movable by a force in the effective direction from an outflow to an inflow from a closing position into an opening position in which the first flow path is opened. The second sealing body is movable by a force in the effective direction from the outflow to the inflow from a closing position into an opening position in which the second flow path is opened.

Abstract: The reel compatible multi-chuck air hose may allow a user to simultaneously inflate multiple tires while providing a lighter and easily stored form factor. The reel compatible multi-chuck air hose may provide four air chucks in series, as opposed to in parallel, with an air source connector at its first end, instead of in the middle of the line. Each of the four air chucks may be connected to the primary hose by a T-connector and may be stored within a dock to keep the air chuck in line with the primary hose. By this design the reel compatible multi-chuck air hose can be rolled around a storage reel for easy storage.

Abstract: In general terms, the present invention relates to a safety valve or a pressure relief valve (PRV) that is developed to be used in combination boilers and similar appliances and utilized for the purpose of controlling or limiting system pressure. Relief valves are generally used as safety devices in systems where fluid pressure is important, and they reduce the system pressure either by discharging fluid from the system or simply by interrupting the fluid conveyance in case of an emergency when there is an increase in pressure. The present invention relates to a pressure relief valve, the rear cover of which is attached to the body by means of a clawed structure and manufactured from entirely recyclable thermoplastic material.

Abstract: A flow control device includes a housing with an inlet and an outlet and a flow conduit disposed in the housing. The inlet, the flow conduit, and the outlet define a flow passage. A valve seat is disposed in the housing downstream of the inlet, and a shuttle is movably disposed in the housing and displaceable between a closed position engaging the valve seat to close the flow passage and an open position spaced from the valve seat to open the flow passage. A sealed chamber is defined between the housing and the flow conduit. A port coupled with a source of pressurized fluid communicates with the sealed chamber, where the shuttle is displaceable between the closed position and the open position based on a pressure in the sealed chamber. The threshold water pressure for displacing the flow conduit may be adjustable by modifying the pressure in the sealed chamber.
