Description

A circular control valve, mounted outside the engine boiler on a steam pipe attached to a dry cap, is made up of two discs on a common stem, some distance from one another. When opening the regulator, at first one of the disks opens steam access to the gap between the disks and thereby balances the vapor pressure on both sides of the spool, facilitating its further promotion, and then the second disk opens the small and large holes of the spool bushing in succession, adjusting the steam access to the machine.

In FIG. 1 shows an external side view of a control box with a sleeve installed with a round slide valve; FIG. 2 - detail of a round collar in a longitudinal section; . 3- detail of the spool bushing in longitudinal section.

On the outside of the engine boiler, a control box 1 is installed, which is generally on one side, to the left of FIG. 1, with a dry cap through a locking vein; 1, silt, and on the other hand, to the right of FIG. 1 with a steam discharge pipe leading to the machine. Inside the box 1, a cylindrical spool bushing 2 is fixed, fitted with windows 8, 9 and 10 (phi 2), with that. windows 9 are the largest size and are located between windows 8 and 10

in the direction along the axis of the sleeve, and the windows 8, having the smallest size, are located on the inlet side of the steam in box 1 and 3 of the dry Kodpak. Inside the sleeve 2 can move in the axial direction of the circular control valve 3 (Fig, E), consisting of two disks 5 and b, mounted on a common rod 4 with some interval between them so that the disk 5, having a smaller thickness, is reversed in the direction of the steam in the box i of the dry cap. The disk 6 has 7 holes in the directions. With the regulator closed, the disk 5 closes the holes 8, and the disk b closes 9 and 10, and when removing the spool 3 from this, they were placed by means of levers and t r controlled from the driver's booth by moving it from right to left in Figures 1 and 2, first the disk 5 opens the windows 8, and the steam penetrates into the gap between the disks, balancing the vapor pressure on the left side of the spool (Fig. 1) and thus facilitating its further movement. Then, with further advancement of the spool, the rear edge of the disk b successively opens first small windows 10, and then large windows 9 and thereby regulates steam access to mazzina. Steam entering the gap between the disks is discharged through the holes 7 in the disk 5 into the vapor-discharge pipe.

The subject matter of the invention.

-, / ,:

Steam regulating spool, characterized in that round spool 3 consists of discs 5 and 6 fixed on the stem some distance from each other, when removing it from the position that blocks steam access to the car, to the left.

first opens the windows 8. act (m through these windows steam balancing the vapor pressure on the left side of the spool, which facilitates its further movement, and then, as the spool continues to be advanced by the machinist, he opens the small 10 and large 9 windows of the spool bushing, thereby adjusting the access couple in the car.,
