    摘要: A cylindrical valve body for a sleeve valve including the valve body to be secured to the upper wall of a reducing chamber and a valve cylinder gate having open upper and lower ends and slidably fitted in the valve body, the gate communicating at its upper end with an inlet elbow for pressurized water. The valve body is formed in its peripheral wall with a multiplicity of straight bores each having a cylindrical nozzle member fixedly fitted therein and provided with an outwardly tapered port. This construction renders the tapered ports easy to form in the wall of the valve body. The tapered port is closable with a plug including a conical head in conformity with the tapered port and a threaded pin projecting from the top end of the head by inserting the plug into the port and screwing a nut on the threaded pin. By altering the number of the tapered ports so closed, the distribution of open ports is variable to improve the flow ratio characteristics of the valve body.

    摘要: A sleeve valve comprises a cylindrical valve body formed with a multiplicity of discharge ports in the peripheral wall and having an upper end secured to the upper wall of a reducing chamber, and a valve cylinder gate having open upper and lower ends and slidably fitted in the valve body, the gate communicating at its upper end with an inlet elbow for pressurized water. A drain tube extending through the bottom cover of the valve body and the bottom wall of the reducing chamber connects the lower end of the sleeve valve to the bottom wall to prevent the vibration of the valve.

    摘要: A valve adapted to control liquid pressure by sliding within a valve housing a bottomed tubular valve closure member having a porous peripheral wall. The pores are subjected to reverse flush by moving the valve closure member to a closed position and also by closing an open end of the valve closure member. The valve housing includes a passage for discharging the liquid from the valve at times of the reverse flush.
