Abstract

The utility model discloses an integrally machined Venturi tube which comprises a Venturi tube main body. Positive and negative pressure lead-in tubes with the diameter of 50mm are disposed on the Venturi tube main body. The positive and negative pressure lead-in tubes are connected with pressure lead-in flanges respectively. The integrally machined Venturi tube leads out pressure more directly and smoothly due to the increased diameter of a pressure tapping tube and the rejection of a piezometer ring, so that work load of sewage disposal and dredge is reduced, and the measuremnt accuracy of the device is improved.

Description

Integral machining type Venturi tube
Technical field
The utility model relates to a kind of integral machining type Venturi tube.
Background technology
Usually the integral machining type Venturi tube of design by parts such as joint flange, venturi body, positive and negative grading ring, positive and negative pressure guiding pipes by being welded.
Because installing positive and negative pressure guiding pipe bore less (Φ 10~Φ 12), this can't adapt to use for a long time under dirty medium or band solid granular ambient condition, because of above-mentioned medium very easily produces grading ring chamber or the obstruction of impulse mouth.
The utility model content
The utility model technical issues that need to address just are to overcome the easy latch up phenomenon of integral machining type Venturi tube of common design, a kind of integral machining type Venturi tube is provided, the utility model is owing to having strengthened pressure mouth of pipe footpath, having cancelled grading ring, thereby pressure is drawn more direct, more unobstructed, thereby reduced the workload of blowdown, mediation, improved the measuring accuracy of device.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of integral machining type Venturi tube of the utility model comprises the Venturi tube body, and described Venturi tube body is provided with positive and negative pressure guiding pipe, and described positive and negative pressure guiding pipe is Φ 50mm pipe.
Positive and negative pressure guiding pipe all is connected with the pressure guiding pipe joint flange.
Described Venturi tube body two ends are separately installed with joint flange.
The beneficial effects of the utility model are: owing to all adopt flange connection between Venturi tube and process pipe and the impulse pipeline, thereby the installation of Venturi tube body, convenient disassembly, pressure draw directly, and the mouth of pipe is unobstructed, the measuring accuracy raising.Just in case the positive and negative impulse mouth of pipe also can directly be opened positive and negative impulse nozzle flange because of the long-term dirty medium of accumulation that uses, the mediation pipeline, and the Venturi tube body is unaffected.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, positive pressure guiding pipe; 2, negative pressure guiding pipe; 3, pressure guiding pipe joint flange; 4, Venturi tube body; 5, joint flange.
Embodiment
As shown in Figure 1, a kind of integral machining type Venturi tube of the utility model comprises Venturi tube body 4, and described Venturi tube body is provided with positive pressure guiding pipe 1 and negative pressure guiding pipe 2; Described positive and negative pressure guiding pipe is Φ 50mm pipe.
Positive and negative pressure guiding pipe all is connected with pressure guiding pipe joint flange 3.
Described Venturi tube body two ends are separately installed with joint flange 5.
Measured medium is drawn from positive and negative pressure guiding pipe, through pressure guiding pipe joint flange, user configured gauge valve and impulse pipeline, links with measurement instrument; Venturi body through being welded to connect and joint flange two ends and process pipe link, thereby reach the purpose that pressure is drawn and measured.The direction of arrow is the measured medium flow direction among Fig. 1.
The utility model is owing to all adopt flange connection between Venturi tube and process pipe and the impulse pipeline, thereby the installation of Venturi tube body, convenient disassembly, pressure draw directly, and the mouth of pipe is unobstructed, the measuring accuracy raising.Just in case the positive and negative impulse mouth of pipe also can directly be opened positive and negative impulse nozzle flange because of the long-term dirty medium of accumulation that uses, the mediation pipeline, and the Venturi tube body is unaffected.
It should be noted that at last: obviously, the foregoing description only is for the utility model example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the present utility model.

Claims (3)

1. an integral machining type Venturi tube comprises the Venturi tube body, it is characterized in that: described Venturi tube body is provided with positive and negative pressure guiding pipe, and described positive and negative pressure guiding pipe is Φ 50mm pipe.
