Description
Technical field
The utility model relates to a kind of water meter and measures pipeline section, particularly utilizes the measurement pipeline section of ultrasonic detection technology metering conduit inner fluid flow band rectification function.
Background technology
The Measurement channel pipeline section used of existing water meter is generally divided into two kinds on process fluid state, the first structure: be only a straight length, this flow pipe section is at fluid through out-of-date, and convection cell, without any rectified action, cannot accurately be measured when flow disturbance is larger.The second structure is the undergauge only comprising straight length and two ends, and the undergauge of this type of flow pipe section can realize the rectification during high flow rate of convection cell, but when low flow velocity, undergauge has not had the rectified action to fluid in pipeline.
Existing water meter measures pipeline section generally by measuring channel, converter mounting shell, sensor penetration pipe and sensor mounting hole are welded, sensor penetration pipe is communicated with sensor mounting hole, converter mounting shell respectively, sensor mounting hole is arranged on measures tube wall both sides, be communicated with pipeline section endoporus, such structure is welded to each other by each parts to form, but welding deformation is large, is difficult to the accuracy requirement ensureing the of each parts own and mutual size and position thereof; Sensor penetration pipe is easy to be destroyed in industry spot, and this will directly affect operational reliability and the sealing of instrument.In addition, this mode production cycle is longer, not easily accomplishes scale production.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Ultrasonic water meter measurement pipeline section with rectification function accurately measured flow, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of Ultrasonic water meter with rectification function measures pipeline section, comprise straight length, be positioned at converter mounting shell above straight length, be connected to the sensor mounting hole of straight length both sides in pairs, be communicated with sensor mounting hole and converter mounting shell penetration pipe and be connected the import undergauge at described straight length two ends respectively and export undergauge, it is characterized in that: the inwall of described import undergauge is connected with the water conservancy diversion rib that schistose texture is dispersed.
In embodiment of the present utility model, described water conservancy diversion rib has eight, and regular distribution is in the vertical and horizontal directions axisymmetricly between two.
On described water conservancy diversion rib, initiating terminal also has chamfering.
In the preferred implementation of utility model, described straight length, import undergauge, outlet undergauge, converter mounting shell, sensor mounting hole, water conservancy diversion rib are integrated casting.
Adopt technique scheme, the water conservancy diversion rib that utility model is dispersed by adding sheet in import undergauge, at undergauge on the basis of high flow rate fluid rectification, rectification can also be carried out to low flow velocity fluid, the error that fluid instability produces can be effectively reduced, the measuring accuracy of flowmeter is further enhanced.In addition, integrally cast by all parts of pipeline section, make pipeline section deformation little, each parts relative-position error is higher, thus ensures the precision of measurement; And the intensity of penetration pipe is effectively improved, ensure that reliability and the sealing of instrument.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the side view of Fig. 1;
Fig. 4 be in Fig. 2 A-A to cut-open view.
In figure:
1-converter holder housing, 2-water conservancy diversion rib, 3-sensor mounting hole, 4-straight length, 5-import undergauge, 5 '-outlet undergauge, 6-penetration pipe, 7-chamfering.
Embodiment
As Figure 1-4, the Ultrasonic water meter with rectification function of the present utility model measures pipeline section, comprises a converter holder housing 1, eight water conservancy diversion ribs 2, two sensor mounting hole 3, straight length 4, import undergauge 5, outlet undergauge 5 ', two penetration pipes 6.
Converter holder housing 1 is positioned at the top of straight length 4, two oblique both sides being arranged on straight length 4 symmetrically of sensor mounting hole 3, penetration pipe 6, between converter holder housing 1 and sensor mounting hole 3, is communicated with converter holder housing 1 and sensor mounting hole 3.This measurement pipeline section is integrated cast structure, and the mutual position error therefore between each parts is less, and this kind of structure pipeline section overall package, Renewal process are very simple and convenient, are convenient to large-scale production.
Shown in composition graphs 4, import undergauge 5 and outlet undergauge 5 ', all in horn-like, are all that one end end that bore is less is connected with straight length 4.Internal diameter and straight length 4 internal diameter of import undergauge 5 and outlet undergauge 5 ' and straight length 4 coupling part are consistent.The center line of import undergauge 5 and outlet undergauge 5 ' and straight length 4 center line are point-blank.Adopt the rectification that such undergauge structure can realize high flow rate fluid to a certain extent.
Water conservancy diversion rib 2 slabbing structure is divergently connected on the inwall of import undergauge 5.These eight water conservancy diversion insist between two axisymmetricly that regular distribution is in the vertical and horizontal directions.On water conservancy diversion rib 2, initiating terminal also has chamfering 7.Like this, except the effect of undergauge rectification, water conservancy diversion rib 2 can also carry out rectification to low flow velocity fluid, thus enables the utility model realize carrying out rectification to the fluid of different in flow rate in pipeline, finally plays the effect of stabilized fluid.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; have in any art and usually know the knowledgeable; if in the protection domain not departing from the claim that the utility model proposes; the Equivalent embodiments that local done by the technology contents utilizing the utility model to disclose is changed or modified, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
