Description

Venturi turbulent flow strong flushing device

Technical field

The utility model relates to the device of flushing sanitation sanitary equipment inner chamber, particularly venturi turbulent flow strong flushing device.

Background technology

In the middle of the prior art, flusher generally all utilizes high pressure water body that high-pressure pump pumps to reach the purpose of flushing by jet pipe ejection fluid at a high speed, but the effect of its flushing still is not very desirable, being limited in scope of flushing, and scouring intensity is not enough.

The utility model content

The purpose of this utility model is to provide a kind of venturi turbulent flow strong flushing device, and it is simple and reasonable for structure, and the flushing scope effectively enlarges, the scouring intensity height.

The purpose of this utility model is achieved in that a kind of venturi turbulent flow strong flushing device, and the scavenging pump outlet is connected with the large port of Venturi tube by pipeline, and the Venturi tube portlet is connected with jet pipe one end;

Described Venturi tube is made of outer tube and core pipe, the core pipe port of export is being provided with its bore of bell of being made of conical pipe bore less than the import of the core pipe other end, this bell stretches in the outer tube, its periphery wall of annular perisporium that is provided with on the core pipe outer tube wall matches affixed with the outer tube internal perisporium, the through hole of offering on the outer tube wall is positioned at conical pipe perisporium periphery, the big opening end of core pipe is communicated with the scavenging pump outlet by pipeline as the water inlet of Venturi tube, this bell stretches in the outer tube as the osculum end, and its port of export of outer tube that is communicated with the core pipe is connected as the delivery port and the jet pipe of Venturi tube.

The utility model utilizes the fluid at different cross section place in the same pipeline and the relation principle of pressure, promptly make full use of the change in flow effect of Venturi tube, high pressure through Venturi tube, the water body of low flow velocity is transformed into low pressure after handling by necking down (bell), the water body of high flow rate sprays by jet pipe, simultaneously owing to can when water body is by the jet pipe ejection, the water body in the external world be brought in the jet pipe at the through hole that plays drainage that bell outer tube is on every side offered, reach water body at a high speed and drive the motion that water body is made turbulent flow, tank wall in storage tank or other cleaners and polishes is washed away the dirt that gets off be suspended in the water body, so that in time discharge by drainage system by turbulent flow.Can learn that by above-mentioned know-why analysis the utility model is simple and reasonable for structure, the flushing scope effectively enlarges, the scouring intensity height.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a main TV structure schematic diagram of the present utility model;

Fig. 2 is the sectional structure schematic diagram of the utility model Venturi tube.

The specific embodiment

A kind of venturi turbulent flow strong flushing device, as shown in Figure 1 and Figure 2, this device is made of scavenging pump 4, jet pipe 1 and Venturi tube 2, and scavenging pump 4 outlets are connected with the large port of Venturi tube 2 by pipeline 3, and Venturi tube 2 portlet are connected with jet pipe 1 one ends;

Described Venturi tube 2 is made of outer tube 7 and core pipe 6, core pipe 6 ports of export are being provided with bell 10 its bores of being made of conical pipe 9 bore less than 6 other end imports 5 of core pipe, this bell 10 stretches in the outer tube 7, annular perisporium 8 its periphery walls that are provided with on core pipe 6 outer tube walls match affixed with outer tube 7 internal perisporiums, the through hole of offering on outer tube 7 tube walls 12 is positioned at conical pipe 9 perisporium peripheries, the affixed drainage tube 13 that is being communicated with on the through hole 12, the utility model is positioned over as in the water in storage tank or other cleaners and polishes, drainage tube 13 will produce outside the jet pipe 1 by the underbalance effect that high-velocity flow produced by bell 10, storage tank water interior or that other cleaners and polishes are interior is sucked in the jet pipe 1, make the state of jet pipe 1 maintenance high speed jet, water body in the storage tank 1 is washed the internal box wall of storage tank 1 or other cleaners and polishes in the mode of turbulent flow; The big opening end 5 of core pipe 6 is communicated with scavenging pump 4 outlets by pipeline 3 as the water inlet of Venturi tube 2, this bell 10 stretches in the outer tube 7 as the osculum end, and outer tube 7 its ports of export 11 that are communicated with core pipe 6 are connected as the delivery port and the jet pipe 1 of Venturi tube 2.This device is at a kind of flusher that utilizes the research and development of venturi jet current principle, when fluid flows out Venturi tube 2, higher flow velocity produces strong disturbance to liquid on every side, thereby produce the water body turbulent flow, the internal box wall of storage tank or other cleaners and polishes is scrubbed in impact, to stick together under the flushing of the dirt on the internal box wall, promptly when fluid passes through the necking section (i.e. the bell 10 that is made of conical pipe 9) of core pipe 6, because the raising of flow velocity makes hydrodynamic improve, thereby the jet length that makes current is able to abundant prolongation, can make water body turbulent flow scope reach needed position in storage tank or other cleaners and polishes by jet pipe 1, and carry dirt with fast speeds and flow to the blowdown main road and discharge the open air with storage tank or the clean blow-off pipe that is communicated with of other health through tool, to reach that storage tank storage tank or other cleaners and polishes internal box wall wall clean fully and the purpose of not staying the dead angle.
