A water nipple controlled by the animal has a valve seat inside a housing. The valve member has an elongate valve shaft providing a forward end at the circular discharge mouth for operation by the animal. A resilient body on the valve member defines a convoluted or serpentine water flow path for flow of water along the flow path through the housing with the flow path defining a rate of flow of the water. A resilient ring is mounted on the valve shaft spaced the valve seat and the forward end with an outside edge of the resilient ring adjacent to and spaced from the inside surface of the housing so as to define an annular channel therebetween through which the water passes so that the resilient ring restricts direct flow of water from the valve seat to the discharge mouth to prevent excess squirting of the water.

A livestock water fountain comprises a first water chamber, a water inlet near the bottom of the first water chamber, and a thermostat in the first water chamber position above the inlet adjacent a preset low-water level in the chamber so as to measure the temperature of the water near the surface of the water. The fountain maybe divided into dual chambers with a wall having a lower passageway for fluid communication which can be plugged to limit water to one of the chambers when water consumption decreases in cold weather.

An animal watering valve includes a housing having an upstream end, a downstream end, a bore extending therebetween, a valve element and a valve actuator located at least in part in the bore, and a plug disposed within the bore upstream of the valve element. The plug includes a lattice structure extending along a length of the plug. The valve element may be a diaphragm disposed within the bore to separate the bore into upstream and downstream portions. The valve actuator has a stem with a stem body extending downstream from a stem head and through an outlet of the housing. The diaphragm includes a sealing surface with first and second annular ridges and a groove disposed therebetween. A stem hat having a cap and disk is coupled to a downstream end of the stem. The disk extends radially from the stem at a location upstream of the outlet.

A pet carrier for carrying pets out is disclosed to include a drinking hole and a kettle holder provided on one side of a pet box that can be carried by hand or on the shoulder. The drinking hole is used to let the dip tube of a kettle insert into the inside of pet box to continuously supply drinking water to the pet. The kettle holder is an elastic belt for holding a kettle in place. When the pet box is not in use, the kettle holder will not hinder the folding and compression of the pet box.

A pet watering system. The pet watering system includes a housing and a waterspout. The waterspout is connected to a water source and is configured to allow water to stream from the water source to the exterior of the housing. The pet watering system also includes a trough, where the trough is configured to receive water that has streamed from the waterspout. The pet watering system further includes a proximity sensor, where the proximity sensor is configured to allow a pet to control the flow of water from the reservoir to the waterspout.

The invention relates to the field of pet supplies, and particularly, to a pet kettle. The pet kettle includes a bottle body, an object holding tray and a switch unit. The bottle body includes a tray groove allowing the object holding tray to be movably placed, and a water outlet channel arranged toward the tray groove. The switch unit is adapted to be switched to an open state or a closed state to control the water outlet channel to be opened or closed. The pet kettle has an integrated structure, which is convenient for carrying and transportation, and prevents pet breeders from consuming a lot of efforts to pour water, thereby saving the pet breeders' energy. In addition, pet breeders do not need to directly contact the water stored in the pet kettle when supplying water, thereby reducing the health risks of the pets and pet breeders.

Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.
