A method of controlling the spray droplet size of a spray nozzle apparatus, in particular for the manufacturing of food powders, delivered to the spray nozzle comprises the following steps: a) providing a paste of a product to be sprayed by a spray nozzle; b) continuously determining the shear viscosity (η) of the product paste delivered to the spray nozzle; c) determining the mass flow rate (Qm) of the product paste delivered to the spray nozzle; d) determining the static pressure (P) of the product paste delivered to the spray nozzle; e) determining the density (p) of the product paste delivered to the spray nozzle; f) delivering the data obtained in steps b) to e) to a control device comprising a computer and a memory; g) calculating control data for adjusting the spray nozzle on the basis of the data obtained in steps b) to e) and on nozzle geometry parameters stored in the memory; h) sending the control data as control signals to a control means of the spray nozzle and adjusting the spray nozzle accordingly.

A water stop switch device includes: a main body, a transmission element and a sealing element; the main body is disposed with a water passage, the sealing element is disposed in the water passage; one end of the sealing element is coupled to the transmission element in transmission way, the sealing element moves in the water passage to open the water passage; the other end of the sealing element and the main body surround to form a chamber; the side wall of the sealing element is disposed with a through hole connecting the water passage and the chamber; when the water passage is open, the chamber is full of water to reduce the pressure difference at two ends of the sealing element.

The disclosure relates to faucet showers and discloses a seal switching mechanism including a seal switching mechanism, which includes a water shunt valve body, a valve shaft provided in an inner middle position of water shunt valve body and elastically connected with an inner bottom end of water shunt valve body, a valve body, a first water outlet channel, a first water outlet, a bubbler, a face cover, a spring, a gasket, a lower sealing port, an upper sealing port located above lower sealing port, a second water outlet, a second water outlet channel, and an assembly groove provided at a lower part of valve shaft. The upper and lower sealing port are arranged inside water shunt valve body, and gasket is installed inside assembly groove. The gasket adopts a special-shaped gasket with a step, which solves switching seal problem of switch sealing ports with different diameters on both sides.

The invention provides a method of packaging a sterilized product. The method includes the steps of providing a product and sterilizing the product. The sterilized product is enclosed in a first layer, which is substantially hermetically sealed to form a first sealed enclosure. The first sealed enclosure is enclosed in a second layer, which is substantially hermetically sealed to form a second sealed enclosure. The second sealed enclosure is enclosed in a third layer, which is substantially hermetically sealed to form a third sealed enclosure. The third sealed enclosure is enclosed in a fourth layer, which is substantially hermetically sealed to form a packaged product.

A rotating sprinkler for irrigation is disclosed. The sprinkler can include a stator spaced upstream from a turbine to form a mixing region therebetween. The stator can define a primary flow path and a bypass flow path. The primary flow path is aligned relative to the plurality of blades so that water exiting the primary flow path traverses the mixing region and impinges on the plurality of blades at a first angle of attack. The bypass flow path is aligned relative to the primary flow path so that water exiting the bypass flow path intersects the water exiting the primary flow path in the mixing region to cause the water exiting the primary flow path to impinge on the plurality of blades at a second angle of attack. The sprinkler can further include a valve configured to regulate flow between the primary flow path and the bypass flow path.

An injector for injecting a fluid includes a base body having an opening and a sealing seat, a spray-orifice disk having at least one spray orifice, and a clamping ring, the spray-orifice disk being disposed in the opening of the base body, and a first nonpositive connection is provided between the spray-orifice disk and the base body, and a second nonpositive connection is provided between the base body and the clamping ring.

A sanitary washing device includes a nozzle, a valve unit, a controller, and a casing. The nozzle is configured to discharge water toward an ano-genital region of a human body. The valve unit is provided on a pipe line between a water supply source and the nozzle. The valve unit includes an electromagnetic valve. The controller is configured to control operation of the nozzle and the valve unit. The casing stores the nozzle, the valve unit, and the controller. The valve unit is disposed further frontward than the controller.

A kitchen shower includes a water outlet mechanism, a switching mechanism and a brush mechanism. The water outlet mechanism is provided with a shower water outlet, a sheet water outlet and a bubble water outlet. The switching mechanism includes a main body, a first switching assembly, a second switching assembly and a third switching component. The first switching assembly is used to switch whether the kitchen shower is out of water, the second switching assembly is used to switch the kitchen shower out of sheet water, and the second switching assembly is used to switch the kitchen shower out of shower water or bubble water. The brush mechanism is detachable and installed on the water outlet mechanism. The brush mechanism can make the kitchen shower clean at the same time of water outlet, so that the cleaning effect is higher.
