A hydraulic balance distributor belongs to the technical field of distributors. Comprising a chassis, a water inlet cavity, a water inlet pipe, a water inlet branch pipe, a manual valve, a water return cavity, a water return pipe, a water return branch pipe and an electric stop valve, the water inlet cavity and the water return cavity are fixed to the left side and the right side of the chassis through fixing supports. The two sides of the water inlet cavity are connected with a water inlet branch pipe and a manual valve, and the two sides of the water return cavity are connected with a water return branch pipe and an electric stop valve. The water inlet pipe is arranged at one end of the water inlet cavity, the water return pipe is arranged at one end of the water return cavity, and the water inlet pipe and the water return pipe are located at the same end. A bypass valve and a blow-down valve are arranged on the side, close to the water inlet pipe, of the water inlet cavity, a connecting pipe and an automatic exhaust valve are arranged on the side, close to the water return pipe, of the water return cavity, and hollow heat preservation and insulation layers are arranged on the water inlet cavity and the water return cavity. And filter screens are arranged between the bypass valve and the blow-down valve as well as between the connecting pipe and the automatic exhaust valve. And exhaust, cleaning, replacement and pollution discharge of the filter screen can be facilitated, and the problem of rapid heat energy loss is solved.

The utility model relates to the technical field of lamps, and discloses an angle-rotatable wall lamp which comprises a rotating bottom column, the front end of the rotating bottom column is rotatably connected with a rotating disc, the front end of the rotating disc is fixedly connected with an inner rotating block, the inner rotating block is internally connected with a rotating block in a sliding mode, the outer portion of the rotating block is connected with a lamp shell in a sliding mode, and the lamp shell is fixedly connected with the rotating disc. A clamping groove block is fixedly connected to the interior of the lamp shell, a clamping rod is slidably connected to the top of the clamping groove block, a large rotating column is rotatably connected to the interior of the clamping rod, a limiting block is rotatably connected to the outer end of the large rotating column, and a transparent lampshade is fixedly connected to the bottom of the limiting block. According to the utility model, the clamping rod is firmly fastened, so that not only is the installation stable and not easy to loosen, but also the internal part of the lampshade can be kept clean at any time through the convenient disassembly and assembly mode, the illumination effect is prevented from being influenced by the shading of light rays by dirt, the loss of the lamp caused by frequent disassembly is reduced, and the overall service life is prolonged.
