SUBSTANCE: straightway stop valve comprises housing with inlet pressure port and outlet port for flowing fluid. The housing receives closure member, driving link of the closure member connected with the handle for valve control, and single-acting positive-displacement servomotor. The pressure chamber of the servomotor is in communication with the inlet port. The straightway stop valve is provided with the preliminary loaded flexible member mounted inside the housing. The movable outlet link of the flexible member is made for permitting single action on the driving link of the closure member and its movement under the action of the flexible member from its any position to the closure position of the closure member. The single-acting positive-displacement servomotor is made so that, under the action of pressure, the pressure chamber provides the action of its output link on the output link of the flexible member directed oppositely to the direction of flexible force of the flexible member and movement of the output link in the position in which it does not act on the driving link of the closure member and driving link can freely move under the external control action between the closure position and open position of the closure member. Under the action of pressure in the pressure chamber, the output link of the flexible member is held in the mentioned above position. When there is no pressure, the output link of the positive-displacement servomotor together with the driving link returns under the action of the flexible member to the closure position of the closure member.

EFFECT: enhanced reliability.

SUBSTANCE: valve comprises seat, overflow unit, and mechanism for lifting the closure member. The seat is secured to the bottom of the tank. The overflow unit is made of a pipe provided with a float. The closure member is mounted at the bottom end of the pipe of the overflow unit. The pipe of the overflow unit is mounted for permitting axial movement by means of the mechanism for lifting the closure member. The closure member is made of pivoting unit, connected with the overflow unit, and kinematically connected with the push-buttons of the large and small drains. The push-buttons are set in the stop bushing mounted in the tank.

SUBSTANCE: double-wash-off valve comprises seat, spillover assembly and shut-off element-lifting mechanism. The seat is fixed at flush tank bottom and incorporates cylindrical shell. The shell bottom is furnished with openings, their upper part communicating with rectangular slots made in the shell wall. The shell accommodates cover enveloping, with a gap, outer pipe and representing barrel. The aforesaid gap makes 0.06 to 0.012 of cover hole diameter. X-bar passes through the inner pipe. The bar lower part rests upon the ledges made inside the aforesaid seat and on the flush hole cylindrical surface. There are hooks on one of the bar walls. The bar is coupled with an extension arm furnished with rectangular holes for the arm to be fitted on aforesaid hooks. Two upper hooks have flanges for the extension arm to be fixed relative to the X-bar. The extension arm upper part has a support bracket with two cylindrical pins mounted one above the other. The aforesaid lifting mechanism represents parallel active and passive levers fitted onto said pins. The active lever represents rocker, its one end being articulated with a radial bracket arranged on the cap nut jointing the spillover assembly pipes. The rocker other end and the passive lever end are articulated with the vertical pushrod, its upper end being sharpened. The major wash-off push button is spring-loaded towards the thrust sleeve with the help of C-like spring and connected with the hollow foot receiving the screw furnished with thrust disk on its lower end. The said disk features corrugated lower surface and circular collar arranged along the disk edges on the corrugated side. The disk rests upon the vertical pushrod sharpened end in its top position before flushing liquid from the flush tank.
