Description

Technical Field

[0001] The utility model relates to a water valve, in particular to a water valve used for a remote intelligent water meter. Background Art

[0002] The water inlet and outlet ports of most common water meters are externally threaded. When in use, the external threads are matched with the nuts of the corresponding pipe interfaces in the water pipes for installation. Currently, there is a remote intelligent valve-controlled water meter on the market, which is provided with a valve control device with wireless transmission on the water meter. The valve control device connects or disconnects the connection between the water meter and the water pipe by controlling the water valve provided on the water pipe. The water valve is installed at the water outlet of the water meter. In the prior art, the water valve and the water meter case are an integrated structure, which has the following disadvantages:

[0003] 1) The material of the meter case and the water valve must be consistent. However, for water meters, there are copper shells, stainless steel shells, cast iron shells and other materials. Water valves made of different materials are not compatible.

[0004] 2) For ordinary water meters, if you need to upgrade them to water meters with intelligent valve control devices, you need to replace the entire meter. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a water valve for a water meter with high compatibility and suitable for being installed on water meter cases made of different materials.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] The water valve of a water meter of the present invention is characterized in that it comprises a threaded connector, a valve body, and a valve stem. The water valve is installed at the water outlet end of the water meter through the threaded connector. At least two lugs extending outward are provided on the top surface of the valve body. The lugs are provided with screw holes for mounting a valve control device of the water valve on the valve body. The valve stem of the water valve can be adaptively connected to the valve control end in the valve control device. The valve stem is driven by the valve control end to open or close the valve built into the valve body.

[0008] The valve is a ball valve.

[0009] The material of the water valve is copper, iron or stainless steel.

[0010] The threaded connector is a nut cap that is movably sleeved on the water inlet pipe of the valve body through a thermal expansion and contraction treatment process.

[0011] Compared with the existing technology, the utility model designs the water valve of the remote intelligent valve-controlled water meter in the existing technology, which is integrated with the meter case, into an independent component separated from the meter case, which greatly improves the installation compatibility of the water valve. When it is necessary to upgrade the ordinary water meter to a remote intelligent valve-controlled water meter, it is only necessary to install the water valve on the pipeline at the water outlet end of the water meter and install the valve control device in conjunction with it to complete the upgrade of the water meter.

[0017] like Figure 1-Figure 3 As shown, the water valve of the water meter 9 of the present invention is suitable for a watch case made of copper, cast iron, or stainless steel. It can also be used for a valve-controlled water valve that is upgraded from an ordinary water meter to a remote intelligent valve-controlled water meter. The water valve is made of copper, iron, or stainless steel.

[0018] The water valve comprises a nut cap 5, a valve body 1, a valve stem 2 and a valve.

[0019] 1. The nut cap 5 has an internal thread and is movably connected to the water inlet pipe of the valve body 1 through a thermal expansion and contraction process. The so-called thermal expansion and contraction process refers to heating the nut cap 5 and cooling the connecting end 6 of the water inlet pipe of the valve body 1 at the same time, and then fitting the two together through pressure. When the temperature returns to room temperature, the nut cap 5 can be freely rotated and movably connected to the connecting end 6 of the water inlet pipe without falling off.

[0020] 2. When the valve body 1 is used on an ordinary water meter, its connection length complies with the requirements of the relevant national mandatory standards. At least two lugs 3 extending outward are provided on the top surface of the valve body 1, and at least two screw holes 4 are provided on the lugs 3. The valve control device 8 of the remote intelligent valve-controlled water meter cooperates with the screw holes 4 through screws or bolts to install the valve control device 8 on the valve body 1. The connection end 7 of the water outlet pipe of the valve body 1 can be an external thread structure or a structure with a nut cap 5.

[0021] 3. Valve stem 2, valve, on the top surface of the valve body 1, there is a through hole connected to the tube space of the valve body 1. The valve is preferably a ball valve, which is placed in the tube space. The top of the ball valve and the valve stem 2 are an integrated structure, and the upper end of the valve stem 2 passes through the through hole and is exposed above the top surface.
