This invention discloses a flushing valve and its control method. The flushing valve includes a valve body, a piston mechanism, and a control device. The valve body has a water storage chamber, a water inlet channel, a water outlet, and a piston chamber. The water inlet channel, water outlet, and piston chamber are all connected to the water storage chamber. The water inlet channel is used to connect to an external water supply source. The piston mechanism is located in the piston chamber and includes a flushing piston and a water control piston. One end of the flushing piston faces the water outlet. The control end of the control device is located in the piston chamber. The control method includes: adjusting the position of the water control piston in the movable chamber through the control device to adjust the water flow direction inside the piston chamber and control the flushing piston to close or open the water outlet. This invention can effectively shorten the path of the water flow from the water outlet. When flushing from the water outlet, the flushing water flow is independent of the piston chamber controlled by the control device, which can effectively increase the water flow rate and water pressure, resulting in a good flushing effect.

This invention relates to the field of composite pipe forming technology and discloses a multi-layer composite lining pressing device for hydrogen embrittlement-resistant austenitic stainless steel pipes. The device includes a machine base with several support platforms fixedly connected to the top. Two water injection chambers are also fixedly connected to the top of the machine base, with water outlets on opposite sides of each chamber. This invention utilizes the fact that the diameter of the fixed flange is smaller than the inner diameter of the composite lining, and the thickness of the rubber membrane is also smaller than the diameter of the composite lining. Therefore, the fixed flange will not contact the composite lining when entering or exiting the pipe. This effectively prevents the problem of defects in the composite lining in the middle section of the pipe caused by the conventional frustum-shaped plugs used to seal the pipe ends. These defects result in poor adhesion between the composite lining and the inner wall of the outer pipe during pressing, reducing the overall forming quality of the pipe.

The application includes: an inlet assembly, a limiting assembly, and an outlet assembly; the limiting assembly includes: a limiting member, a movable frame, and a baffle plate; the inlet assembly has a first outlet; the limiting member is disposed within the movable frame; the baffle plate is connected to the movable frame, and one end of the baffle plate is connected to the first outlet; one end of the movable frame is connected to the outlet assembly; the inlet assembly and the outlet assembly are connected; the inlet assembly is used to connect to a water source, the first outlet is used to discharge water from the inlet assembly through the first outlet, the inlet assembly and the outlet assembly are connected to form a water storage cavity, the movable frame is movably disposed within the water storage cavity, used to move the baffle plate, the baffle plate is used to block the first outlet under water pressure, the limiting member is used to limit the movement distance of the movable frame within the water storage cavity, and the outlet assembly is used to discharge water from the water storage cavity.

The utility model relates to fire fighting equipment detection technical field discloses a kind of fire door anti-spraying water impact tester, including fire hose, the inside left side of fire hose is fixedly connected with round, the inside fixedly connected with cylinder in round, the outside sliding connection of cylinder has slip ring, the outside right side of slip ring is fixedly connected with spring a.In the utility model, first, slip ring is pushed back under the action of water flow pressure and is slid on cylinder to round inside, let water flow pass smoothly, when water flow appears backflow trend, slip ring will be quickly reset under the action of spring a elasticity, form tight seal, to block reverse water flow, simultaneously, when rotating handle on top layer moves down, water flow resistance increases by thread transmission to drive pressing plate to move down, inside flow cross-sectional area reduces at this time, water flow resistance increases;Conversely, the extrusion force of water decreases, water pressure reduces, it is convenient to adjust and change hose pass diameter, promote the progress of experiment.

This utility model discloses a pressurized coffee component extraction device, belonging to the field of coffee component extraction. The pressurized coffee component extraction device includes a coffee machine, a pressurized water inlet connected to the output end of the coffee machine, a filter pot disposed on the front of the coffee machine, the filter pot being fitted onto the surface of the pressurized water inlet, coffee powder stored inside the filter pot, a support being disposed at the bottom of the filter pot, and a transmission structure disposed on the surface of the coffee machine. The transmission structure utilizes the support to drive the filter pot upwards and change the distance between it and the pressurized water inlet. The transmission structure includes a connecting frame fixedly connected to the right side of the coffee machine. This utility model directly adjusts the impact force of the high-pressure water flow on the coffee powder by changing the distance between the filter pot and the pressurized water inlet. A smaller distance increases the water pressure and improves extraction efficiency; a larger distance reduces the pressure and avoids over-extraction, thus solving the problem of gradual concentration reduction caused by traditional fixed pressurization.
