Abstract

The invention makes it possible to increase the reliability of a steam trap when operating on contaminated condensate. The diameter of the closure member 9 is larger than the diameter of the cylindrical channel 8. During the purge, the drain valve 19 is opened and the condensate is drained to the drain. The pressure in the cumulative cavity 7 drops and the gas passes from the cavity 5 into the cavity 7, affecting the foreign organ. After the end of the purge, the valve is closed, and the pressure in the cavity 5-7 is leveled using inclined grooves 12. 2 Il. to the drains

Description

113

The invention relates to devices that provide for the release of condensate from vessels under excessive pressure.

The purpose of the invention is to increase reliability when operating on contaminated condensate.

FIG. 1 shows a steam trap, a general view, FIG. 2 shows section A-A in FIG. one,

Koidensatootvodchik contains a vertical housing 1 with a transverse partition 2 having a central 3 and 4 peripheral holes. Partition Channel 2 divides the housing 1 into the entrance 5 and the working, 6 cavity. In the lower part of the housing 1 there is a cumulative cavity 7, communicated with the working cavity 6 by a cylindrical channel 8.

8 case 1 is placed a valve, the valve body 9 of which is placed in the working cavity 6 and is made with a conical surface 10, interacting

with a central opening 3 of the partition 2 and with a conical section 11 tapering in the direction of the cylindrical channel 8, in the housing 1 at the point of communication of the working cavity 6 with the cylindrical channel 8 there are inclined grooves 12, the bottoms 13 of which are parallel to each other forming the conical section 11 locking of the organ 9. The diameter of the locking organ 9 is larger than the diameter of the cylinder-. 8. The valve stem 14 is provided with guide plates 15 placed in the cylindrical channel 8. In the accumulation cavity 7 there is an arah of quina 16, which interacts with the rod 14. In the bottom of the housing 1, the drain channels 17 are installed. valve 19, the condensate drain valve 5 is connected to the drainage e 5kosti,

During the period when the condensate was filled with condensate, the organ was trapped.

9 under the action of the spring 16 is in its highest position and overlaps the central opening 3.

Condensate from the inlet cavity 5 through the holes 4 enters the working

cavity 6, then through cylindrical channel 8 into accumulative cavity 7. During purge, drain valve 19 is opened, condensate from accumulative cavity 7 is through, drain channels 17 are drained. The pressure in the accumulation cavity 7 drops, the gas flow from the inlet cavity 5 passes into the accumulation cavity 7 and, acting on the locking body 9, pushes it down. The conical section 11 of the locking member 9 closes the cylindrical channel 8. After the end of the purge, the valve 19 is closed. The pressure in the cavity 5-7 is aligned with the help of inclined grooves 12. Under the action of the spring 16, the locking member 9 returns to its highest position.

Formula inventions

A steam trap containing a vertical housing with a transverse partition with central and peripheral holes and dividing the housing into the inlet and working cavities, an accumulative cavity in the lower part of the housing, connected to the last cylindrical channel, placed in the housing of a spring-loaded valve the working cavity and is made with a conical surface interacting with the central opening of the septum, and the valve stem is provided with guide plates placed in cyl Indic channel, characterized in that, in order to increase reliability when operating on contaminated condensate, the locking member is made with a diameter exceeding the diameter of the cylindrical channel and with a tapered section tapering in the direction of the latter and a cylindrical channel there are inclined grooves, the bottoms of which are parallel to the generatrix of the conical section of the closure member.
