SU1553742A1 - Hydraulic lock valve of exhaust system outlet pipe - Google Patents

Abstract

The invention relates to mechanical engineering and will allow to increase the reliability of the operation of a hydraulic lock in the event of a pulse change in the pressure differential in a gas exhaust pressure system. The exhaust pipe is placed in the beaker 3, and a cap 6 is mounted above it with a side surface formed by two truncated cones connected by small bases. The narrowed section 7 and the cavity under the cap are connected by means of impulse tubes 8 and 9 to the servomotor 10, which controls the position of the tap of the tap 11. The latter communicates via cup 12 the cup 3 either with the tank 13 for storing the liquid or with the drain fitting 14. The cups 3 are installed in the body of the hydraulic seal around the circumference relative to the gas outlet pipe 2 and their number is equal to the number of inlet pipes connected in parallel to the body 4. The tank 13 is located behind the outer surface of the body 1 in the form of an annular tank equipped with an overflow pipe The pipe 16. The supply and discharge of fluid is controlled by the pressure difference between the cavity under the hood and the narrowed section, and the level of the liquid in the tank is maintained in the plane of the narrowed section by means of an overflow pipe. 1 hp f-ly, 1 ill.

Description

The invention relates to the field of mechanical engineering and can be used in gas exhaust systems of internal combustion engines connected to a single gas outlet pipe.

The aim of the invention is to improve the reliability

The drawing shows a diagram of the hydraulic valve of the gas exhaust pipe of the exhaust gas system.

The hydraulic lock 1 comprises a housing 1 with a gas outlet pipe 2. Around the circumference of the gas outlet pipe, glasses 3 are installed in the housing 1, each of which contains an inlet pipe 4 ,, connected to the exhaust system of an individual engine. The side surface of the cup 3 is made in a de-truncated cone in the upper part of which the output section for gases forms an outlet nozzle 5. Each input nozzle is equipped with a cap 6, the lateral surface of the cory is made in the form of two truncated cones connected with small bases the zone of their connection of the narrowed section 7 for the passage of gases. Half-open under the cap and a narrowed section by means of impulse tubes 8 and 9 are connected to a 10S servo-motor connected to the valve of a crane 11, connected together by means of a pipe 12 a cup 3 in its lower part with a tank 13 for storing the liquid and a drain fitting 14. Tank 13 is made AND in the form of an annular tank behind the outer surface of the housing 1. The upper level of the hydraulic seal fluid is located in the narrowed section 7, and the lower level 15 is located between the outer surface of the cap and the glass. At one level with a narrowed section 7 in the tank 13 is overflow pipe 16.

Trap works as follows.

In the exhaust pipe of the stopped engine, there is no gas movement

Consequently, there is no pressure separation between the space under the hood and in the narrowed section 7 of the hydraulic seal. As a result, the servomotor 10 holds the valve 11 in the position in which the tank 13 communicates

50

When one of the engines in its inlet nozzle 4 is turned off, the movement of gases ceases and, accordingly, the pressure differential between the space under the cap and the narrowed section 7 disappears. In this case, the servomotor 10 switches the edge stopper 1 1 to a position at which Can 3 is connected to line 12

drawing). In the exhaust pipe of a running engine, gases are moved, as a result of which in the space under the hood and in the constricted section 7 a pressure differential occurs, perceived by the servo motor 10. At that, the valve 11 of the valve 11 is set to position 5 reporting the cavity of the glass 3 by means of pipeline 12 with the discharge pipe 14 therefore, there is no liquid in the water seal and the gases move freely into the glass 3 and through the outlet 5 enter the free space of the housing 1 (as shown by the arrows on the left side). drawing style). From the housing 1, the gases are removed through the gas outlet pipe 2 to the utilization boiler for further use. Since a working engine creates pressure pulses in the exhaust pipe and ducts, in the free space of the housing 1, the pressure in the time interval is pulsed.

Since the upper level of the barrier seal fluid is located in a constricted section of the space with a cap, the pressure pulses generated by the engine in case 1 are perceived by the hydraulic shut-down engine in a significantly weakened form. This prevents fluid from being thrown into the exhaust system of an inactive engine and the reliability of the exhaust path increases.

In addition, the connection of several inlet pipes through independent water locks to a single common gas outlet pipe allows refusing the installation of utilization boilers, in terms of the number of engines

When one of the engines in its inlet nozzle 4 is turned off, the movement of gases stops and, accordingly, the pressure differential between the space under the hood and the narrowed section 7 disappears. In this case, the servomotor 10 switches the valve plug 1 1 to a position where

No. 3, therefore the fluid levels in the tank 13 and the narrowed section 7 are the same (as shown on the right side

and the liquid flows from the tank 13 to the water seal and it is put into operation.
