Abstract

This invention relates to devices for draining condensate from pneumatic systems operating under pressure. The invention improves reliability. At. When a certain level of condensate is reached (K), the float (P) 6 floats up and through the rod (C) 16 acts on the plate 12. The latter rotates and the tube 8 opens, together with the atmosphere 1. The pressure above P 6 drops and it floats, raising the drain valve 9. At the same time, the pressure above and below P 6 equalizes; . As a result, the spring 11 acts on the saddle 10, the plate 12 under its own weight rotates and presses the sealing element 19 to the tube 8. K is drained from the housing 1. As the level K decreases, the float 6 is lowered and the valve 9 closes the outlet channel 2. When lowering P6 it through C 16 acts on the plate 12, increasing the force of its pressing to the tube 8. Adjusting nuts 13 are installed on the C 16. 1 sludge. § (L N9 00 00 4 1C

Description

This invention relates to a device for draining condensate from pneumatic systems operating under excessive pressure.

The purpose of the invention is to increase reliability.

The drawing shows a condensate trap, a general view.

The steam trap comprises a housing 1 with an outlet channel 2 in the bottom 3. On the bottom 3 there is a cylindrical cup 4 with slots 5 near the bottom 3. In the cup 4 there is a float 6 with a through central hole 7 in which it is installed; and tube B, to the lower end which is attached a drain valve 9, and to the top - a control valve, made in the form of a saddle 10 with a cylindrical spring 11 placed between it and the float 6 and a closure member 12 in the form of a plate 12, hinged at one end 13 on the saddle 10. On the free (end 14 plates 12 are made a slot 15 in which a threaded rod 16 is placed, connected to the upper end of the float 6 by a hinge 17. On the rod 16, on either side of the plate 12, adjusting nuts 18 are additionally placed. The locking organ- plate 12 has a sealing element 19. Between the body 1 and the glass 4 in the upper part of the installed filter element 20.

In the absence of condensate, the float 6 is in the lower position. The drain valve 9 under the action of the weight of the float 6 and the overpressure in the housing 1 intersects the exhaust channel 2. The sealing element 19 of the plate 12 is pressed by the spring 11 to the seat 10 and locks the tube 8. As the condensate accumulates in the housing 1, the float 6 floats up, compressing the spring 11 . When a certain level of condensate is reached, the float 6,

pops through the rod 16 acts on the plate 12, the latter rotates, the tube 8 opens, together with the cavity of the housing 1 with the atmosphere, the pressure above the float 6 drops and the float 6 floats, raising the drain valve 9. In this case the pressure above and below the float 6 is equalized as a result, the spring 11 acts on the saddle 10, the plate 12 rotates under its own weight and presses the sealing element 19 to the tube B. The condensate drains out of the housing 1. As the level of condensate decreases, the float 6 goes down and the drain block valve 9 closes the outlet channel 2. When the float 6 is lowered, it acts on the plate 12 by means of the rod 16, increasing its force on the tube 8.
