Abstract

The utility model discloses a kind of rectification nozzle, comprise mouth body and run through the runner of mouth body, it is characterized in that, described runner is formed by three sections, that is: entrance straight section (1), converging transition (3) and outlet straight section (4); Outlet straight section (4) is provided with commutator segment (5), and commutator segment can reduce scattering degree and the turbulence intensity of the liquid of nozzle ejection, thus improves fluid column flushing hitting power, makes developing result better.The washer jet that the utility model provides can provide the cleaning fluid column that turbulivity is less and hitting power is larger.

Description

Rectification nozzle
Technical field
The utility model belongs to fluid flushing apparatus field, particularly relates to a kind of rectification nozzle.
Background technology
At present, utilizing pressure water column docking net-fault insulator to carry out periodic flushing is the effective measures avoiding railway contact line insulator pollution flashover.The insulator charged water of electric railway rinses equipment and utilizes train operation gap to realize charged flushing operation, greatly improves operating efficiency, significantly reduces labour intensity.In this equipment, the structure of nozzle and processing precision direct influence developing result.The current scattering degree penetrated due to existing nozzle and turbulivity are comparatively large, thus cause the flushing hitting power of the water column sprayed less, affect developing result.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of rectification nozzle is provided, it can solve existing water flooding nozzle because its current scattering degree penetrated is comparatively large and turbulence intensity is comparatively large, and the problem that the flushing hitting power of the water column of the ejection caused is less.
The technical scheme that the utility model adopts is: a kind of rectification nozzle, and comprise mouth body and run through the runner of mouth body, it is characterized in that, described runner is formed by three sections, that is: entrance straight section 1, converging transition 3 and outlet straight section 4; Outlet straight section 4 is provided with commutator segment 5.
The inner chamber of described entrance straight section 1 and outlet straight section 4 is cylindric.(inner chamber of 3 is coniform to the convergent of described nozzle, and the external diameter of converging transition is reduced to the external diameter of outlet straight section 4 gradually by the external diameter of entrance straight section 1, and the internal diameter of converging transition is reduced to the internal diameter of outlet straight section 4 gradually by the internal diameter of entrance straight section 1.
Described commutator segment 5 is sheet, and its length is less than the length of jet expansion straight section 4.Described commutator segment is four, and is distributed on the internal diameter of jet expansion straight section.Described commutator segment is sheet, and its length is less than the length of jet expansion straight section.
The beneficial effects of the utility model are: press water is through mouth body outlet ejection after three sections of runners, and commutator segment reduces scattering degree and the turbulence intensity of the liquid of nozzle ejection, thus raising fluid column rinses hitting power, makes developing result better.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Fig. 2 is left view of the present utility model.
In figure: 1. entrance straight section; 2. runner; 3. converging transition; 4 outlet straight sections; 5. commutator segment.
Detailed description of the invention
By reference to the accompanying drawings utility model is described further; but protection domain of the present utility model is not limited only to following embodiment; namely the simple equivalence in every case done with the utility model claim and description changes and modifies, and all still belongs within the utility model patent covering scope.
As shown in Figure 1, 2, mouth body is provided with entrance straight section 1, converging transition 3 and outlet straight section 4, mouth body inside is provided with the flow channel for liquids 2 running through body, mouth body outlet straight section 4 is provided with multiple commutator segment 5, commutator segment 5 can reduce scattering degree and the turbulence intensity of the liquid of nozzle ejection, thus improve fluid column flushing hitting power, make developing result better.
Entrance straight section 1 inner chamber of described nozzle is cylindric.
Outlet straight section 4 inner chamber of described nozzle is cylindric.
Converging transition 3 inner chamber of described nozzle is coniform, and its external diameter is reduced to the external diameter of outlet straight section 4 gradually by the external diameter of entrance straight section 1, and its internal diameter is reduced to the internal diameter of outlet straight section 4 gradually by the internal diameter of entrance straight section 1.
Described commutator segment 5 is four, and is distributed on the internal diameter of jet expansion straight section 1.
Described commutator segment 5 is sheet, and its length is less than the length of jet expansion straight section 1.
