Abstract

The invention discloses a cut-off copper valve for a water heater, which comprises a valve body, the top of the valve body is fixedly connected with a valve cover through first bolts, a sealing gasket is arranged between the valve body and the valve cover, and the bottom of the inner cavity of the valve body is arranged There is a water inlet, a hot water port is provided on the left side of the bottom of the water inlet, a cold water port is provided on the right side of the bottom of the water inlet, a connecting body is provided in the inner cavity of the valve body, a short rod is installed through the inner cavity of the connecting body, and the bottom of the short rod It runs through the bottom of the connecting body and extends to the inner cavity of the valve body. The top of the short rod is fixedly connected with a horizontal block, and the bottom of the short rod is fixedly connected with a valve clack. The top is movably connected with a threaded rod, and the inner cavity of the valve body is fixedly connected with a retaining ring suitable for the valve clack. The top of the threaded rod runs through the valve body and the bonnet from bottom to top and extends to the top of the bonnet. The invention can set the temperature of the outlet water of the pipeline according to the needs, and also has the function of check, which is highly practical.

Description

Technical field [0001] The invention relates to a cut-off valve, in particular to a cut-off copper valve for water heaters, and belongs to the technical field of valves. Background technique [0002] The shut-off valve, also known as the shut-off valve, is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome , Is the friction force between the valve stem and the packing and the thrust produced by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem should be large, otherwise the valve stem will bend failure, three-way The shut-off valve is also a kind of shut-off valve. The three-way shut-off valve can control the flow direction of the medium. The three-way shut-off valve does not have the function of c...
