By adopting the technical scheme, different abrasives are involved in the jet flow with different speed gradients due to different centrifugal forces, so that the covering surface and the stripping effect of the abrasives can be increased when the jet flow formed by the water flow impacts the pipe wall.

Preferably, the switch valve comprises a plurality of valve plates arranged in an array manner and a valve pressing member driving the valve plates to move, and the valve pressing member drives the valve plates to open and close the water supply end of the pipe fitting and communicate with the cleaning device in a hydraulic manner.

Through adopting above-mentioned technical scheme, adopt fluid pressure type chuck structure, press the valve block to drive the valve block through hydraulic means and do the centering and draw close the motion along the center of pipe fitting for the closed passageway of valve block is opened when wasing the inner wall of pipe fitting, and the pipeline is sealed by the valve block.

Preferably, the blowdown assembly is rotatably connected with a rotary impeller, and a throttle valve is arranged at the tail end of the blowdown assembly.

Through adopting above-mentioned technical scheme, because rivers are by rotatory impeller throw-away center, form negative pressure zone at rotatory impeller center to the reinforcing is to the adsorption affinity of scaling, and the choke valve can reach the regulation flow through the sectional area that changes the valve clack, thereby changes the exhaust velocity of rivers, makes the abrasive material more fully contact with the pipe wall.

Compared with the prior art, the utility model has the beneficial effects that:

the flow direction of the water flow is changed through the blades, but the water flow generates vortex due to the sudden loss of fluid inertia to form high-speed jet flow, physical waves are formed by using the water flow as a medium to impact and vibrate the pipe wall, and therefore the scale on the pipe wall is peeled.

Detailed Description

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the designated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A scale removal component of a plastic pipe fitting is shown in figures 1-6 and comprises a pipe fitting 2, a cleaning device 1 is installed at a water supply end of the pipe fitting 2, a pollution discharge assembly 3 is installed at a water outlet end of the pipe fitting 2, the cleaning device 1 is provided with a gradient centrifugal pump, the gradient centrifugal pump is provided with a plurality of centrifugal impellers 8, the centrifugal impellers 8 form water flow into high-speed jet flow through blades 9, and the cleaning device 1 is provided with a switch valve used for switching the communication between the pipe fitting 2 and the gradient centrifugal pump.

In normal use the passage of the gradient centrifugal pump to the water supply end of the pipe 2 is closed by a switch valve and water flows through a pipe in the centre of the centrifugal impeller 8.

When will wash the scaling of 2 inner walls of pipe fittings, wherein, the ooff valve includes the valve block 5 that a plurality of arrays were arranged and drives the valve block 6 of valve block 5 activity, presses valve block 6 to drive the intercommunication of the water supply end and the belt cleaning device 1 of 5 switching pipe fittings of valve block 2 through hydraulic means, and the ooff valve adopts fluid pressure type chuck structure, presses valve block 6 to drive valve block 5 through hydraulic means and makes the centering and draw close the motion along the center of pipe fitting 2 for valve block 5 confined passageway is opened and the pipeline is sealed by valve block 5.

In rivers got into the gradient centrifugal pump, later rivers got into centrifugal impeller 8 after, because the blockking of blade 9, but self produces the vortex because fluid inertia loses, and because the blade 9 figure of centrifugal impeller 8 is the gradient along the direction of height of pipe fitting 2 and increases progressively, the hindrance size that blade 9 figure influences rivers and receive led to the fact velocity of flow gradient, make the efflux that the gradient centrifugal pump flows out form different velocity gradients, carry out impact and vibrations of different degrees with rivers as the physical wave that the medium formed behind the efflux left the gradient centrifugal pump, thereby peel off the scaling of pipe wall.
