The second stage includes an outer valve plug having an upstream portion and a second tapered portion extending downstream from the upstream portion. The bushing includes a shoulder, and the cap is configured to engage the shoulder to actuate the outer valve plug to the open position.

Spray heads for use with desuperheaters and desuperheaters including such spray heads. One example of a spray head includes a main body having an exterior surface and defining a central passage, the main body adapted for connection to a source of fluid, at least one entrance port formed in the main body along the central passage, and at least one spray nozzle arranged adjacent the exterior surface of the main body. The spray head also includes a plurality of flow passages, each of the plurality of flow passages providing fluid communication between the entrance port and an exit opening of the spray nozzle. A first one of the plurality of flow passages follows a first non-linear path and has a first distance, and a second one of the plurality of flow passages follows a second non-linear path and has a second distance different from the first distance.

A liquid outlet device for reagent kit includes a spray pipe and a nozzle that is arranged at one end of the spray pipe, where each blocking strip extends along an axial direction of the spray hole and one end of each blocking strip is provided with a shoulder that extends towards a center of the spray hole. The spray pipe includes a spray pipe body, a plurality of blocking strips and a magnet bar that is movable along the axial direction of the spray hole in a space defined by the shoulders and the blocking strips. The nozzle includes an annular sleeve connected with the spray pipe body through threaded connection or clamped connection, an end plate, a nozzle pipe, a conical nozzle opening and an annular blocking flange.

Spray heads for use with desuperheaters and desuperheaters including such spray heads. One example of a spray head includes a main body having an exterior surface and defining a central passage, the main body adapted for connection to a source of fluid, at least one entrance port formed in the main body along the central passage, and at least one spray nozzle arranged adjacent the exterior surface of the main body. The spray head also includes a plurality of flow passages, each of the plurality of flow passages providing fluid communication between the entrance port and an exit opening of the spray nozzle. A first one of the plurality of flow passages follows a first non-linear path and has a first distance, and a second one of the plurality of flow passages follows a second non-linear path and has a second distance different from the first distance.

A water spray gun for control of an outflow of water and adjustment of the amount of the outflow is revealed. The water spray gun includes a handle portion, a pipe portion connected to the handle portion and used for spraying water, and a control device arranged at the position where the pipe portion meets the handle portion. The control device comprises a press part and a rotary control member. The amount of the water outflow is controlled by the rotary control member. The amount of the outflow sprayed out from the pipe portion at respective stages is continuously controlled and regulated by the control device.

A sanitary washing device includes a nozzle, a valve unit, a casing, and a toilet seat. 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, and includes an electromagnetic valve. The casing stores the nozzle and the valve unit. The casing includes a low portion positioned below the toilet, and a high portion positioned backward of the low portion. A length in a vertical direction of the high portion is greater than a length in the vertical direction of the low portion. The valve unit is disposed in the low portion. A length in the vertical direction of the valve unit is less than a length in a longitudinal direction, and less than a length in a lateral direction.

A pre-rinse spray valve includes a spray face assembly that includes a spray face fixture that includes a face plate and a rear end flange. The face plate defines a plurality of spray holes extending axially through the face plate. Each of the plurality of spray holes is defined in part by a conically diverging surface projecting from the back side of the face plate. Overmold bores are defined through the outer periphery of the face plate. An overmold is a unitary structure that continuously covers a peripheral region of the upper surface of the face plate, a side rim of the face plate and a peripheral ledge of the face plate. The overmold includes cords, and each of the cords threads through a respective one of the overmold bores to permanently attach the overmold to the face plate.

A multifunctional pull-out spray head includes a switching assembly, a water inlet assembly, and a water outlet assembly. The switching assembly controls three waterways of a switching assembly main body through a first button, a first switching unit and a second switching unit. The water inlet assembly realizes on-off control of the switching assembly. The spray head realizes the switching of three spray modes and meets the user's demand for multiple functions. The overall structure is compact, the size is small, and the operation is convenient.
