The invention belongs to the technical field of ultrasonic non-destructive detection and relates to a jet flow immersion ultrasonic detecting method and a liquid sprayer. According to the detection method, a symmetrical radial flow injection mode is adopted for controlling coupling agents in a flowing mode, so that uniformity of injected flow and initial speed are ensured. A double-layer multi-hole screen structure is arranged on a coupling agent flowing channel, so that double-layer rectification is achieved to obtain a stable laminar condition. The liquid sprayer is composed of a nozzle, a first bolt assembly, a first sealing ring, a liquid sprayer base body, a first liquid injection nozzle, a probe clamping sleeve, a second sealing ring and a second liquid injection nozzle. Due to the reverse arc inner surface of the nozzle, the possibility that due to the fact that high-pressure flowing liquid impacts the inner wall, turbulence is formed on the inner wall is reduced, and the turbulence intensity level on an ultrasonic transmitting channel is lowered; the number of assemblies in the liquid sprayer is small, and therefore the structure is compact and simple; the method is used for carry out ultrasonic detection on focus type ultrasonic probe jet flow immersion, parts can be detected automatically on machines, operation is easy to carry out, the structure is reliable, and the efficiency is high.

The smoke generator is provided with a cooling system.

The invention discloses a flow uniformity sleeve and a flowmeter equipped with a flow uniformity sleeve, comprising a first flow uniformity piece and a second flow uniformity piece opposite to the first flow uniformity piece, the first flow uniformity piece includes multiple a plurality of first flow equalizers, a plurality of first flow equalizers are provided with a plurality of first flow equalizers, and a plurality of first flow equalizers are superimposed on each other in a one-to-one correspondence with the first flow uniformity holes, so The second flow equalizer includes a plurality of second flow equalizers, and a plurality of second flow even holes are opened on the plurality of second flow equalizers. One-to-one correspondences are superimposed on each other. The flow uniforming sleeve of the present invention sieves the originally unstable fluid through the first flow evening piece and the first flow evening piece, so that the fluid is converted from the turbulent flow in the original state into a multi-beam stable laminar flow, and the preparation The process is simple, so that the flow meter equipped with the uniform flow sleeve can obtain accurate flow data in the subsequent measurement.

The invention relates to a gravity type water purification device, which relates to the technical field of water purification treatment. Since the water purification capacity of the existing water purification device is not adjustable, it is more likely that the purified water is still mixed with a lot of particles Case. This scheme includes the flocculation area, the water purification sedimentation area and the fine filtration area in sequence along the water flow direction. The water flow direction of the water purification sedimentation area is from bottom to top. There are several arrays of water purification channels fixed in the water purification sedimentation area. The water channel is arranged obliquely; two parallel connecting frames are installed in the water purification sedimentation area, and several adjusting pieces are fixedly connected between the two connecting frames. Each adjusting piece corresponds to a water purification channel, and the adjusting piece passes through the corresponding The water purification channel is attached to the inner wall of the water purification channel; a drive assembly is installed in the water purification sedimentation area. The driving assembly can make the adjusting sheet stick to the inner wall of the water purification channel or be away from the inner wall, thereby changing the hydraulic radius of the water purification channel, thereby changing the water purification capacity.

A flow sensor (1) comprising a flow channel (14) embedded in a base body (1′), a flow sensor element (13) adjacent to the flow channel (14) and a cover plate (12) covering the flow channel (14) and arranged on the base body (1′). The flow channel (14) is formed by an elastic sealing lip (15) which delimits the channel (14), running on and around an upper side of the base body (1′) lying opposite the cover plate (12) such that a seal is formed. This arrangement allows the formation of a sealed structure where a flow channel (14) with a level channel that avoids contamination and turbulence and has laminar current flowing through the flow channel (14).
