Description
Technical Field
The utility model relates to a mounting structure especially relates to a be applied to flow sensor mounting structure of pipeline.
Background
A liquid flow sensor is a flow sensor. The working principle is as follows: when the measured liquid flows through the sensor, the impeller is forced to rotate under the action of the fluid, and the rotating speed of the impeller is in direct proportion to the average flow speed of the pipeline. The rotation of the impeller periodically changes the magnetic resistance value of the magnetic circuit, the magnetic flux in the detection coil periodically changes along with the change of the magnetic resistance value, induced electromotive force with the frequency same as the rotation frequency of the blades is generated, and the induced electromotive force is amplified and converted and processed.
The connection mode of the existing flow sensor and the pipeline is as follows: the pipe is communicated with the cylinder, the core rod of the flow sensor penetrates through the cylinder and extends into the pipe, and one end, far away from the pipe, of the cylinder is in threaded connection with the sealing cover for pressing the core rod. When needing to overhaul or change flow sensor, need unscrew sealed lid and take out flow sensor, because the pipeline area is pressed, in case take out flow sensor can cause the water injection and go out for change the operation unusual difficulty.

Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of a portion A of FIG. 1;
shown in the figure:
1. main water supply pipeline 2, water supply branch pipe 3, connector 4, installation tube head 5, standing groove 6, rubber seal ring 7, bolt 8, plug 9, valve switch.
Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1 and 2, the utility model discloses a water supply trunk line 1, two water supply branch pipes 2 that connect in parallel on water supply trunk line 1 all are equipped with flow sensor installation mechanism on every water supply branch pipe 2, all connect two valve switch 9 on every water supply branch pipe 2, and two valve switch 9 are located flow sensor installation mechanism's both sides respectively.
Flow sensor installation mechanism includes the connector tube head 3 with 2 rigid couplings of water supply branch pipe and intercommunication, can dismantle the installation tube head 4 of being connected with connector tube head 3, and the lumen of connector tube head 3 communicates and is coaxial with the lumen of installation tube head 4. The core rod 8 of the flow sensor passes through the mounting pipe head 4 and the connecting pipe head 3 and extends into the water supply branch pipe 2. Two placing grooves 5 are arranged on the inner wall of the pipe cavity of the mounting pipe head 4, and the two placing grooves 5 are distributed along the axial direction of the mounting pipe head 4. And a rubber sealing ring 6 is arranged in each placing groove 5, and each rubber sealing ring 6 is sleeved on the core rod 8. Realize the sealing connection of plug 8 and installation tube head 4 through rubber seal ring 6, avoid the junction infiltration.
In the present embodiment, in order to achieve effective fixing of the mandrel 8, a bolt 7 which abuts against the mandrel 8 is screwed onto the mounting nipple 4, and two rubber sealing rings 6 are located between the bolt 7 and the connecting nipple 3. The position arrangement can realize sealing before fastening, and avoid water seepage at the tightly-pressed part.
In this embodiment, the connector stub 3 is screwed to the mounting stub 4.
When the water supply device is used, one of the two water supply branch pipes 2 is selected for use, namely when one water supply branch pipe 2 runs, the other water supply branch pipe 2 is used for standby, the two valve switches 9 on the running water supply branch pipe 2 are both opened, and the two valve switches 9 on the standby water supply branch pipe 2 are both closed. When the flow sensor on the operation water supply branch pipe 2 needs to be replaced and disassembled, the two valve switches 9 on the standby water supply branch pipe 2 are firstly opened, then the two valve switches 9 on the operation water supply branch pipe 2 are closed, the operation water supply branch pipe 2 stops supplying water, and therefore the pipe head 4 can be detached and installed to replace the new flow sensor.
The main water supply pipeline 1 is divided into two water supply branch pipes 2, and the flow sensor can be conveniently replaced by switching the two water supply branch pipes 2.
Of course, the above description is not limited to the above examples, and technical features of the present invention that are not described in the present application may be implemented by or using the prior art, and are not described herein again; the above embodiments and drawings are only used for illustrating the technical solutions of the present invention and are not intended to limit the present invention, and the present invention has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that changes, modifications, additions or substitutions made by those skilled in the art within the spirit of the present invention should also belong to the protection scope of the claims of the present invention.
