Abstract
The invention discloses a grouting pressure-stabilizing valve which comprises a valve body. The valve body is of a cylindrical hollow structure. A valve element is arranged in the valve body. One end of the valve body is connected with a three-way body. The other end of the valve body is connected with a pressure adjusting rod. An elastic piece is installed between the pressure adjusting rod and the valve element. The elastic piece is located in the valve body. A locking piece is arranged on the pressure adjusting rod. One end face of the locking piece makes contact with one end face of the valve body. A pressure relief port connector is installed on the upper side face of the valve body. The axis of the pressure relief port connector and the axis of the valve body are perpendicularly arranged. The valve element moves horizontally so that the inner cavity of the pressure relief port connector can be disconnected from and communicated with the inner cavity of the three-way body.
