The integrated structure of the cylindrical cup-shaped body and a pipe section body enables all the communication connection cables to be located in the cylindrical cup-shaped body uniformly, complex external cable connection is avoided, a circuit is protected from damage, the structure is simpler and beautiful, and the cost of the whole machine is lowered. An inlet end and an outlet end of the installation pipe are set to be horn-shaped openings and transit with arc edges, the stability of a flow field is improved, the installation connecting ports of the transducers are located in an isometric section in the middle of the installation pipe, namely the transducers at an emitting end and a receiving end of a pipe section are both located in the isometric section, the influence on flow measurement from the change of the flow field is reduced, and measuring accuracy is improved.

Description

Ultrasonic water meter

Technical field

The utility model relates to a kind of ultrasonic water meter, is specifically related to a kind of transducer and calculator modules mounting pipe segment structure of ultrasonic water meter.

Background technology

Most of ultrasonic water meter pipeline section inside is without arc transition in the market, and current are bigger than normal by pipeline section internal drag, increased crushing.In pipe segment structure, the flow sensor of transmitting terminal and receiving end is all outside isometrical section.The conventionally independent project organization part of calculator modules is for fixing mainboard, battery and other components and parts, therefore the communication between each module needs complicated cable to connect, so neither attractive in appearance, also makes product in the middle of production or actual use, cable is easily pullled, and wrecks.

Utility model content

The purpose of this utility model is to provide that a kind of measuring accuracy is high, calculator modules fixed sturcture and the integrated ultrasonic water meter of mounting pipe.

The disclosed this ultrasonic water meter of the utility model, comprises mounting pipe, transducer and calculator modules, has the mounting interface of transducer and the cylindrical cup-shaped body for fixing described calculator modules on the sidewall of mounting pipe.

Described cylindrical cup-shaped body is perpendicular to mounting pipe setting; comprise columniform sidewall; its upper end wall body inside height is lower than outside; there is the sealed groove of twice annular inner side; in sealed groove, there is corresponding sealing strip; outside wall body is connected with snap ring, is useful on the tempered glass of sealing calculator modules between snap ring and sealing strip, and the upper end of snap ring is connected with protection and renovates.

On described cylindrical side wall, be useful on the line outlet that described calculator modules communication wire cable passes, line outlet is supporting wiring protecting cover.

The interlude of described mounting pipe inner chamber is isometrical section, and two ends are the hydraucone about the flaring of interlude symmetry, and the junction of bell-mouthed inside surface and interlude is arc-shaped edges, improves the stability in flow field, reduces crushing.

The mounting interface of described transducer is inclined in the upper and lower sides of described mounting pipe in pairs, and they are total to longitudinal center line, and this center line is arranged in the part of described mounting pipe inner chamber in its isometrical section, for guaranteeing the Measurement accuracy of transducer.

Between the inner of described transducer and described mounting interface, be crimped with O-ring seal, the outer end of mounting interface is connected with transducer over cap.

The structure of placing calculator modules is designed to cylindrical cup-shaped body to the utility model and pipeline section body forms one; avoid prior art to set up independently structural unit and placed calculator modules; integrated structure makes all communication wire cables be unified in cylindrical cup Interior Solutions certainly; avoid the cable of external complex to connect; both protected circuit not to be damaged; make simple in structurely, and create an aesthetic feeling, has also reduced complete machine cost simultaneously.The oral area of cylindrical cup-shaped body arranges double density sealing groove, effectively realizes the degree of protection of IP68 by the crimping of tempered glass.In in the middle of the mounting pipe isometrical section of the mounting interface of transducer, the transducer of pipeline section transmitting terminal and receiving end, all in isometrical section, has greatly reduced the impact of flow field change on flow measurement, carries and has done measuring accuracy.

Fig. 2 is that the master of Fig. 1 looks cross-sectional schematic.

The cross-sectional schematic of mounting pipe in Fig. 3 Fig. 2.

Embodiment

As shown in Figure 1 to Figure 3, the disclosed this ultrasonic water meter of the utility model, comprises mounting pipe 1, transducer 2 and calculator modules 3.On the sidewall of mounting pipe 1, there are the mounting interface 11 of transducer 2 and the cylindrical cup-shaped body 12 for fixing calculator modules 3.

The interlude of mounting pipe 1 inner chamber is isometrical section, and two ends are the hydraucone about the flaring of interlude symmetry, and the junction of bell-mouthed inside surface and interlude is arc-shaped edges.The mounting interface 11 of transducer 2 is inclined in the upper and lower sides of mounting pipe 1 in pairs, and they are total to longitudinal center line, and this center line is arranged in the part of mounting pipe 1 inner chamber in its isometrical section, makes the transducer 2 of transmitting terminal and receiving end all in isometrical section.Between the inner of transducer 2 and mounting interface 11, be crimped with O-ring seal 4, the outer end of mounting interface 11 is connected with transducer over cap 5.Cylindrical cup-shaped body 12 arranges perpendicular to mounting pipe 1; comprise columniform sidewall 121; its upper end wall body inside height is lower than outside; there is the sealed groove of twice annular inner side; in sealed groove, there is corresponding sealing strip 122; outside wall body is connected with snap ring 123, is useful on the tempered glass 124 of sealing calculator modules 3 between snap ring 123 and sealing strip 122, and the upper end of snap ring 123 is connected with protection and renovates 125.On columniform sidewall 121, be useful on the line outlet 1211 that calculator modules 3 communication wire cables pass, line outlet is supporting wiring protecting cover 126.

Principle of work is as follows: the structure of placing calculator modules 3 is designed to cylindrical cup-shaped body 12 and forms one with mounting pipe 1; avoid prior art to set up independently structural unit and placed calculator modules 3; the inside that integrated structure makes all communication wire cables be unified in cylindrical cup-shaped body 12 solves; avoid the cable of external complex to connect; both protected circuit not to be damaged; make simple in structurely, and create an aesthetic feeling, has also reduced complete machine cost simultaneously.The oral area of cylindrical cup-shaped body 12 arranges double density sealing groove, effectively realizes the degree of protection of IP68 by the crimping of tempered glass 6.By the entrance point of mounting pipe 1 with endpiece is arranged to hydraucone and with arc-shaped edges transition, improve the stability in flow field, in in the middle of mounting pipe 1 isometrical section of the mounting interface 11 of transducer 2, be that the transducer 2 of pipeline section transmitting terminal and receiving end is all in isometrical section, thereby reduce the impact of flow field change on flow measurement, carry and do measuring accuracy.
