SU767450A1 - Condensate removal device - Google Patents

Description

The invention relates to a device for removing liquid from closed cavities, for example, from pipelines under excessive pressure, and can be used for continuous purging of steam boilers. ^;

Known steam trap containing a housing with an inlet and outlet tubes, placed in a · open-type float, with a shut-off element of the exhaust valve installed in its bottom adjacent to a seat made at the end of the exhaust pipe [1].

The main disadvantage of the known steam trap is its low reliability due to the unilateral impact of the condensate stream on the float, which leads to the warping of the float relative to the vertical, destruction of the exhaust valve. ed

The aim of this invention is to increase reliability.

This goal is achieved by the fact that the inlet pipe is made with perforated side walls and is installed inside the float coaxially with the outlet pipe.

The steam trap contains a housing 1 with ⁵ inlet and outlet tubes' Z 3, respectively. In the housing 1 posted by the float 4 open type. In the bottom 5 of the float 4 is installed a shutoff member 6 of the exhaust valve adjacent to the seat 7 made at the end of the exhaust pipe 3. The side walls 8 of the inlet pipe 2 are perforated. In the lower part of the housing 1 there is a drain plug 9, and in the 'cover 10 of the housing 1 there is an air vent 11. On the inner surface of the housing 1, limiters 12 for lateral movements of the float 4 are installed. In the bottom 13 of the housing 1, an abutment 14 of the lower position of the float 4. is installed. ·

Condensate, together with steam and air, enters the housing 1 through the inlet pipe 2 and is sprayed through the perforation of the side walls 8 onto the inner surface of the float 4. The accumulator in the upper part of the housing 1 is 10

Claims (2)

Claim A steam trap comprising a housing with inlet and outlet tubes, an open-type float with 5 by a locking body installed in its bottom 3, the spirit and, partially, the steam is discharged from the housing 1 through the air vent 11. When the float is filled with a certain amount of condensate, the float drops down, opening the exhaust valve, i.e. the locking member 6 moves away from the seat 7. Through the hole formed between the last condensates due to internal pressure in the housing 1, the vapor pressure is ejected through the exhaust pipe 3 from the housing 1. Implementation of the inlet tube with perforirovannymi'bokovymi walls and installing it inside the float coaxially outlet tube improves the device operation reliability due excluded _g cheniya buckling and fracture of the float of the exhaust valve due to the impact of the incoming condensate stream. exhaust valve adjacent to the seat made on the end of the exhaust pipe, characterized in that, in order to increase reliability, the inlet pipe is 10 yen with perforated side walls and is installed inside the float coaxially with the exhaust pipe. * Sources of information taken into account during the examination ¹ 15 1.
