Abstract

A pressure-adjustable concealed shower valve includes a shell, containing an embedded body with water channels. A cover board that communicates with the water channels is arranged on the body. The body is provided with channels for hot water and cold water. The hot water channel and cold water channel are provided with a partition wall with a hole. The partition wall separates water inlets and outlets of the hot water channel and cold water channel. A buffer unit that can be opened and closed is arranged on the partition wall. The buffer unit contains a fixed adjustment screw and the corresponding booster spring and the central rod. The end of the central rod matches with the hole on the partition wall and can form an open or close structure. The partition wall and the buffer unit are arranged away from the straight line in which the water channel is located.
