The utility model discloses a flange can manage independent setting with the flow, avoids because of flange shelters from, influences the processing of flow pipe, and in addition, when flow pipe and corresponding tube coupling, flange can the certain angle of longshore current buret circumferential direction to offset the radial error between corresponding connecting hole on connecting bolt and the flange.
Description
Technical field
The utility model relates to a kind of Water gauge component, is specifically related to the joint flange for watermeter flowing rate pipe.
Background technology
Flowtube is the vitals of intellectual water meter, and for docking with fluid circuit, in conjunction with related sensor, fluid flow, temperature, pressure and other parameters are measured, and is controlled and display unit to water meter by data transfer.For guaranteeing to be connected with the reliable of fluid circuit, the two ends of flowtube, namely entrance point and endpiece are provided with joint flange, traditional joint flange is normally integrated with flowtube, due to the restriction of size and shape, when processing the sensor slot of flow near end portions, very inconvenient.Meanwhile, flange and the one-body molded manufacture of flowtube more easily form trachoma, the defects such as crackle, reduce the manufacture qualification rate of flowtube, thus add the manufacturing cost of flange flowtube.
In addition, after flowtube is connected with pipeline, if pipeline rotates, because flange and flowtube are integrated, flowtube certainly will also can rotate with pipeline, cause water meter to tilt, thus can not guarantee that ultrasonic transducer can measurement in the horizontal direction, and then affect the accuracy of water meter measurement data.
Utility model content
In view of this, the utility model is provided for the joint flange of watermeter flowing rate pipe, facilitates the processing of flowtube, and can prevent flowtube to meet accident rotation with respective line, affects water meter measurement accuracy.
Its technical scheme is as follows:
A kind of joint flange for watermeter flowing rate pipe, this joint flange entirety is in circular, middle part is provided with flowtube mounting hole, described joint flange is surrounded by the left body of the flange being all semi-annular shape and the right body of flange and forms, this joint flange side outer wall is provided with the annular groove caved inward, and described annular groove internal diameter is equal with the external diameter of flowtube mounting hole.Adopt above structure, joint flange can be separate with flowtube, carries out the installation of joint flange after first can completing the processing of flowtube again, avoids because blocking of joint flange affects flowtube working (machining) efficiency.In addition, the joint flange of this structure utilizes annular groove and flowtube mutually chimeric, and non-immediate rigidity be fixed in flowtube, when flowtube is connected with respective line by joint flange, joint flange can turn an angle along flowtube circumference, to offset the radial error between coupling bolt connecting hole corresponding on flange.In the course of work, as respective line rotates, can produce relative rotation between joint flange and flowtube, guarantee water meter not run-off the straight, thus ensure the accuracy of measurement of water meter.
As preferably, the left body of described flange is identical with the right body structure of flange, and be oppositely arranged, described flange left body one end has the first outwardly protuberance, the other end is provided with first depressed part suitable with this protuberance, the right body one end of described flange is provided with the second protuberance, the other end is provided with the second depressed part, this first protuberance embeds in described second depressed part, second protuberance is mutually chimeric with the first depressed part, is provided with at the left body of this flange and the mutual nested position of the right body of flange the lock-screw radially penetrated.This structure enables together with the left body of flange is closely adhered to the right body of flange, and the assembling between convenient and flowtube.
As preferably, described flowtube mounting hole hole wall is provided with to projecting inward circular fin, to improve strength of joint further, and guarantees the positiver sealing between joint flange and flowtube.
Circumferentially connecting hole is distributed with, to be connected with respective line outside described flowtube mounting hole.
Beneficial effect:
Joint flange of the present utility model, independently can arrange with flowtube, avoid because joint flange blocks, affect flowtube processing, in addition, when flowtube is connected with respective line, joint flange can turn an angle along flowtube circumference, to offset the radial error between coupling bolt connecting hole corresponding on flange.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model;
Fig. 3 is the cut-open view along A-A place in Fig. 1;
Fig. 4 is the using state figure that the utility model and flowtube are installed.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
A kind of joint flange for watermeter flowing rate pipe as shown in Figure 1, it is overall in annular, and middle part is provided with flowtube mounting hole 1, is circumferentially distributed with multiple connecting hole 7 outside flowtube mounting hole 1.
This joint flange surrounds form by being all the left body of semicircular flange 2 and the right body 3 of flange, and this joint flange side outer wall is provided with the annular groove 4 caved inward, and described annular groove 4 internal diameter is equal with the external diameter of flowtube mounting hole 1.
Composition graphs 2 can be found out, the left body of flange 2 is identical with flange right body 3 structure, and be oppositely arranged, flange left body 2 one end has the first outwardly protuberance 21, the other end is provided with first depressed part 22 suitable with this protuberance 21, flange right body 3 one end is provided with the second protuberance 31 in corresponding first depressed part 22 position, the other end is provided with second depressed part 32 corresponding to the first protuberance 21, this first protuberance 21 embeds in the second depressed part 32, second protuberance 31 is mutually chimeric with the first depressed part 22, the lock-screw 5 radially penetrated is provided with at the left body of this flange 2 and the mutual nested position of the right body 3 of flange, to make together with the right body 3 of the left body of flange 2 and flange can be closely adhered to.
Refer to Fig. 3, flowtube mounting hole 1 hole wall is provided with to projecting inward circular fin 6, and this circular fin 6 is roughly positioned at the medium position of flowtube mounting hole 1 length direction.
As shown in Figure 4, the flowtube 8 applying joint flange of the present utility model is the tubular structure of hollow, its two ends are in outwardly hydraucone shape, sensor slot 9 is provided with near its end position, joint flange of the present utility model is arranged on flowtube 8 end positions, this flowtube 8 is provided with in corresponding annular groove 4 position the boss 81 radially protruded, and is provided with annular groove 82 in corresponding circular fin 6 position.
