Abstract

The utility model relates to a movable flange pipe section, which belongs to the field of pipeline connecting parts and is provided with a pipe section body. Two ends of the pipe section body are provided with annular clamp grooves, clamp rings are mounted in the clamp grooves, outer edges of the clamp rings are provided with outer inclined surfaces, the pipe section body is sleeved with a flange disc, and the inner side of the flange disc is provided with inner inclined surfaces matching with the outer inclined surfaces on the clamp rings.

Description

Movable flange pipe section
Technical field
The utility model relates to the pipe joint field, at length says it is that a kind of loose flange connects pipeline section.
Background technique
As everyone knows, dual mode is generally adopted in existing pipe coupling connecting means, a kind of is to be cast with a flange respectively in pipe ends, be processed with bolt hole on the flange, two sections pipes need be received a time-out, two adjacent flanges are close, rotate pipeline and make two bolt hole alignment on the flange, be inserted into bolt in the bolt hole then and tighten, this mode is fit to thinner pipeline, when pipeline is more big and heavy, just need many people could the swinging heads road in the time of be with the alignment of adjacent bolt hole, time-consuming, require great effort, take a lot of work; Another kind of mode is chucking hoop of suit outside adjacent pipe coupling, as CN2514205Y disclosed " flange-type Fast-mounting tube fitting ", it includes body, supported flange, snap ring, packing ring, seal ring and is enclosed within tube end in regular turn, be connected and fixed by bolt, the conical surface of sealed rubber ring just in time is inlaid in the taper seam of body, the endoporus tapered slope of supported flange is set on the snap ring, snap ring one end is provided with conical surface, the snap ring inwall is provided with the teeth bar, this flange Fast-mounting tube fitting complex structure, the cost height, sealing effect is poor in addition.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of movable flange pipe section, can the quick connecting pipe road, and simple in structure, good sealing effect.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of movable flange pipe section, be provided with the pipeline section body, pipeline section body two ends are processed with annular slot, snap ring is installed in the draw-in groove, the snap ring outer is processed with outer inclined-plane, be set with flange plate on the pipeline section body, the inboard of flange plate be processed with snap ring on the interior inclined-plane of wedging mutually, outer inclined-plane.
The beneficial effects of the utility model are, can the quick connecting pipe roads, and simple in structure, good sealing effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a pipeline section main body structure schematic representation.
Fig. 3 is the structural representation of flange plate.
Fig. 4 is the structural representation of snap ring.
1. pipeline section bodies among the figure, 2. draw-in groove, 3. flange plate, 4. in the inclined-plane, 5. snap ring, 6. outer inclined-plane.
Embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model is provided with pipeline section body 1, pipeline section body 1 two ends are processed with annular slot 2, snap ring 5 is installed in the draw-in groove 2, snap ring 5 outers are processed with outer inclined-plane 6, be set with flange plate 3 on the pipeline section body 1, the inboard of flange plate 3 be processed with snap ring 5 on the interior inclined-plane 4 of wedging mutually, outer inclined-plane 6, be processed with bolt hole on the flange plate 3.
The utility model at first is sleeved on flange plate 3 on the pipeline section body 1 when using, then two snap rings 5 are stuck in the draw-in groove 2, interior inclined-plane 4 on outer inclined-plane 6 on the snap ring 5 and the flange plate 3 is wedging mutually, the flange plate 3 of pipeline body 1 is alignd with flange plate on the pipeline, and rotation flange plate 3 makes two bolts hole on the flange plate corresponding, inserting also, swivel bolt is close together two adjacent flange plate, the outer inclined-plane 6 on the snap ring 5 is embraced on interior inclined-plane 4 in the process that tights a bolt on the flange plate 3 tightly, thereby pipeline section body 1 and pipeline are linked together.
The utility model especially is suitable as the table body of ultrasound water meter, ultrasonic flowmeter is to be used for the amount of liquid of measurement flow piping, two ultrasonic wave sensors are installed in the relative position of inner-walls of duct respectively, one is used for the emission ultrasound, another is used to receive ultrasound, and the regulation of NBS make helical vane type water meter length of pipe section and flange diameter restrictions the installation of ultrasonic wave sensor.Will dwindle its setting angle for the ease of installing, and setting angle dwindle the shortening that has caused sound path (i.e. distance between two ultrasonic wave sensors), be unfavorable for measuring, if want to increase the setting angle that sound path just must increase ultrasonic wave sensor, and the flange of pipe ends has blocked the bearing of trend that ultrasonic wave sensor is installed, and the efficient of installing and processing is greatly reduced.On the end positions of pipeline section body 1, be processed with through hole respectively, ultrasonic wave sensor is installed in the through hole, then flange plate 3 is fixed on pipe end, the setting angle of ultrasonic wave sensor is not subjected to the restriction of flange plate 3, thereby can increase sound path as required effectively, and the efficient of installing and processing is improved greatly.

Claims (1)

1. movable flange pipe section, be provided with the pipeline section body, it is characterized in that: pipeline section body two ends are processed with annular slot, snap ring is installed in the draw-in groove, the snap ring outer is processed with outer inclined-plane, be set with flange plate on the pipeline section body, the inboard of flange plate be processed with snap ring on the interior inclined-plane of wedging mutually, outer inclined-plane.
