The utility model discloses a valve device and gas water heater, valve device includes valve body and valve core subassembly, and valve body is equipped with valve cavity and with the water inlet channel, first water outlet channel and second water outlet channel of valve cavity intercommunication, and first water outlet channel has with the first water pass -through of valve cavity intercommunication, and second water outlet channel has with the second water pass -through of valve cavity intercommunication, first water pass -through is located in the peripheral wall surface of valve cavity, valve core subassembly includes the rotation axle of rotation in the valve cavity and the first valve core and second valve core of fixedly being equipped with the rotation axle and being spaced, and first valve core is rotated with the peripheral wall surface of valve cavity and is shielded or open first water pass -through, is used for adjusting the on -off area of valve cavity and first water outlet channel, and second valve core rotates in the valve cavity to shield or open second water pass -through, is used for adjusting the on -off area of valve cavity and second water outlet channel. The utility model discloses technical scheme the utility model discloses technical scheme can reduce the fluctuation range of gas water heater water temperature, and promotes the constant temperature performance.

This invention provides a self-floating, steplessly shifting water intake device and its usage method. The device includes an intake tower and, sequentially arranged from upstream to downstream, a floating gate slot, a stacked beam slot, an emergency maintenance gate slot, and an arc-shaped working gate slot within the intake tower. The floating gate slot contains a floating gate that can slide up and down along the slot with the water level. The stacked beam slot contains stacked beams. The floating gate forms a U-shaped flow surface, through which surface water flows into the downstream channel. An overhang is located at the bottom of the downstream surface of the floating gate, and the end of the overhang has a water-stopping device that contacts the stacked beams in the downstream stacked beam slot. The stacked beams consist of multiple sections; some stacked beams are placed in the stacked beam slot to block water, while others are stored in a stacked beam gate reservoir. The bridge crane is used to adjust the number of stacked beam sections in the stacked beam slot according to changes in the reservoir water level. This invention enables the intake of surface water with stepless floating gate displacement and adapts to large fluctuations in water level.

The utility model discloses a kind of washing and draining integrated pump structures of feeding bottle cleaning machine, including cup body, water inlet is equipped on it, first water outlet pipe and second water outlet pipe;Drain pump, it is communicated with the first water outlet pipe;Washing pump, it includes the water connection pipe communicated with the second water outlet pipe;Connecting hose, its two ends are respectively sleeved on the second water outlet pipe and the water connection pipe, to connect and communicate two. The utility model provides a kind of washing and draining integrated pump structures of feeding bottle cleaning machine, by utilizing connecting hose, while guaranteeing water, reduce the vibration of washing pump conduction to cup body, to reduce noise, avoid the case of resonance.
