Description

Technical Field

[0001] This utility model relates to the field of valves, and in particular to a remote control device for water pipe valves. Background Technology

[0002] Currently, residential communities use individual water meters for billing. On the one hand, when water bills are in arrears, water companies typically shut off water supply by locking the valves. However, after payment, users often have high expectations for the water company's restoration time. On the other hand, newly delivered communities often have high vacancy rates, which can easily lead to air entering the water meters and causing them to idle. Both of these situations require manual valve closure, which is time-consuming and labor-intensive. Replacing electrically controlled valves is costly and time-consuming. Therefore, this application aims to design a remote control device for water pipe valves, which can easily interface with existing valves for remote control. Utility Model Content

[0003] This utility model provides a remote control device for water pipe valves, which can be equipped with valves of different sizes within the range. It can remotely control the closure of water pipe valves, and has a simple structure and is easy and quick to install.

[0004] The technical solution to the above-mentioned technical problems is: a remote control device for water pipe valves, including a housing, a cover fitted to the housing, a cavity at the upper end of the housing, a drive motor fixedly installed in the cavity, a spline sleeve fixedly installed at the output end of the drive motor, a spline shaft slidably installed in the spline sleeve, a positioning plate fixedly installed at the lower end of the spline shaft, two first positioning rods symmetrically arranged at the lower end of the positioning plate, a sliding groove opened on the positioning plate on the same side of each first positioning rod, a rotating ring sleeved on the spline shaft, connecting rods symmetrically arranged on the rotating ring, a second positioning rod fixedly installed on each connecting rod, the two second positioning rods sliding in the two sliding grooves respectively, a threaded sleeve connected to the lower end of the spline shaft, and a locking ring fixedly installed on the outer circumference of the spline shaft at the lower end of the threaded sleeve.

[0005] As a preferred embodiment of this utility model, the housing and the cover are provided with through holes through which a water supply pipe passes.

[0006] As a preferred embodiment of this utility model, the locking ring is an inverted frustum shape that gradually decreases in size from top to bottom. The locking ring can be inserted into the gap between the rotating ring and the spline shaft to lock the rotating ring.

[0007] As a preferred embodiment of this utility model, a signal transceiver assembly is provided inside the cavity.

[0008] The beneficial effects of this utility model are:

[0009] 1. This avoids the current problem of high economic costs and long time cycles associated with replacing large quantities of electrically controlled valves to achieve automatic shut-off of water meter valves.

[0010] 2. It can be adapted to valves of different sizes to a certain extent. Attached Figure Description
