Description

Technical Field

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

[0002] Water supply flow control devices are used to control the flow rate of water. They are mainly connected to the water supply pipeline through valves and then controlled. They are widely used in various water supply applications and are key equipment to ensure the stable operation of the water supply system and achieve efficient use of water resources. However, most control devices currently have valves buried directly underground, protected by brick wells and cast iron manhole covers. Due to various factors such as environment, design, construction materials, and maintenance, the manhole covers and casing covers are not airtight, allowing rainwater or surface water to enter. In particular, the large temperature difference between the inside and outside of the casing causes internal moisture to condense into water, resulting in long-term water accumulation outside the valve. This causes inconvenience for personnel to operate, shortens the service life of the valve, and affects the safe operation of the device and the water supply pipeline. Utility Model Content

[0003] The main objective of this invention is to provide a flow control device for water supply, which can effectively solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A flow control device for water supply includes a flow valve body and a waterproof cover. The waterproof cover is located outside the flow valve body. A top cover is fixedly installed on the upper end of the waterproof cover. A connecting ring is integrally formed on the bottom of the waterproof cover. A sealing sleeve is fixedly installed on the lower end of the connecting ring. Connecting retaining rings are fixedly installed on both sides of the lower end of the waterproof cover. A water level measuring structure is fixedly installed on the outer side of the waterproof cover.

[0006] As a further embodiment of this utility model, a lifting ring is movably installed on the upper end of the outer cover, and a switch indicator is provided on the upper end of the outer cover on one side of the lifting ring.

[0007] As a further embodiment of this utility model, the sealing sleeve is located in the middle of the two connecting rings, and the connecting rings on both sides are symmetrically arranged and installed.

[0008] As a further embodiment of this utility model, a valve handle is movably installed at the upper end of the flow valve body, connecting rings are sleeved on both sides of the flow valve body, a sealing sleeve is fitted and connected to the center top of the flow valve body, and a waterproof cover is sleeved on the outside of the valve handle.

[0009] As a further embodiment of this utility model, the water level measuring structure includes a mounting collar, a locking screw, a sensor mounting plate, a water level sensor, and a sensor wire. The mounting collar is fitted over the outside of the waterproof cover, the locking screw is threaded onto the end of the mounting collar, the sensor mounting plate is welded to the front of the outer side of the mounting collar, the water level sensor is installed through the inner side of the sensor mounting plate, and the sensor wire is fixedly installed at the upper end of the water level sensor.

[0010] As a further embodiment of this utility model, the water level sensor penetrates through the sensor mounting plate and is located in front of the waterproof cover and the main body of the flow valve.

[0011] Compared with the prior art, the present invention has the following advantages: by using a sealing sleeve to seal the valve, and by fitting connecting rings on both sides of the flow valve body, the entire device is installed and sealed to the flow valve body. Then, the valve handle of the flow valve body is waterproofed and sealed by a waterproof cover to prevent water from seeping into the valve handle when water accumulates. This ensures that the valve control part is not affected by rainwater and surface water seepage, improves the service life of the valve, prevents water accumulation from causing inconvenience to personnel, and reduces the impact on the safe operation of the device and water supply pipeline.

[0012] With the addition of a water level sensor, when water accumulates on the outside of the flow valve body, the water level sensor detects the water accumulation and sends a signal. The sensor wire is connected to the display terminal, and the system reports the water accumulation in the operating environment of the flow valve body, enabling operators to remove the water in a timely manner.
