SK278564B6 - Device for noise removing of controlling valve - Google Patents

Abstract

The valve used for rapid air outlet purposes (28) controlling the small space (11) closed to the pressure vessel (1) is connected to the outlet exhaust pipe (4) with the use of the connecting pipe (32) or with the use of the pipe shore (18) passing through the pressure vessel (1). In the mouth place of the connecting pipe (32) coming into the exhaust pipe (4), there is the intermediate piece (33), having a shape closed to Laval nozzle lowering the air overpressure in the connecting pipe (32).

Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a device for removing noise from a control valve of a label remover or vault of a furnace device or a container and silo. 5

BACKGROUND OF THE INVENTION

To date, these label removers, the essential part of which is a large space for collecting working compressed air and a small space for compressed air to control the inlet port into the outlet exhaust pipe by means of a piston or diaphragm, have a quick vent valve or solenoid valve. During their operation, the compressed air is released into the free space, causing noise exceeding the specified standards. So far, silencers mounted on this exhaust port have been used, reducing noise by about 10%, which is low and does not comply with Regulation 20 of the standard.

SUMMARY OF THE INVENTION

According to the invention, the noise of this valve is completely eliminated by supplying the outlet port of the quick-bleed valve to which the special silencer is supplied is fed to a manifold which is connected to an exhaust exhaust pipe through which the compressed air is guided to its point of application. therefore, the compressed air does not enter the free space at all and the noise is eliminated. The interconnecting pipe from the quick vent valve is connected to the outlet exhaust pipe, on new devices through a tubular strut 35 passing through the pressure vessel, or on previously manufactured devices, this interconnecting pipe is connected to the outlet exhaust pipe downstream of the pressure vessel. A nozzle in the shape of a Lavala nozzle is located in the outlet exhaust pipe at the inlet of the manifold into the exhaust manifold to reduce air overpressure in the manifold.

Significantly better noise reduction parameters are achieved by the device according to the invention, without regular maintenance of the silencer, which is clogged with dirt, oil, dust and moisture.

BRIEF DESCRIPTION OF THE DRAWINGS

The device will be explained in more detail by way of illustration, in which FIG. 1 is an overall view of the device in working position, and FIG. 2 shows a detailed embodiment with a membrane.

DETAILED DESCRIPTION OF THE INVENTION

The pressure vessel 1 is provided with a flange 6 to which a lid 7 with a diaphragm 9, a sealing ring 60 12, a return spring support 16 and a rubber damper 15 is attached. The diaphragm separates a large space 10 from a small space 11. 14 compressed air. By deflecting the diaphragm 9 with the sealing ring 12, the compressed air path is released from the large space 65 10 via the orifice 30 into the outlet exhaust pipe 4, which passes through the center of the pressure vessel 1.

The compressed air supply 22 from the compressor continues with the solenoid valve 23, the feed line 24 and the other feed line 25 through the check valve 26 through the filling port 17 to the pressure vessel 1. The branch 27 ducts into the quick vent valve 28 with the outlet port 29 and from there to the inlet 14 Compressed air into the small space 11 at the age of 7. From the quick-vent valve 28 with the outlet opening 29, the outlet air duct 32 extends through or into the new exhaust pipe 4 through the pressure vessel 1 into the exhaust pipe 4 or into the outlet pressure pipe 4. At the outlet of the manifold 32 into the outlet exhaust pipe 4, there is a Lavala nozzle 33 in the outlet exhaust pipe 4, which reduces the air overpressure in the manifold 32. At its outlet end, the outlet exhaust pipe 4 is provided with a flange 19 on the outlet. connection to input extension 20 of the process device 21 with labels 31.

A small space 11 as well as a large space 10 through the filling opening 17 are pressurized through the quick-air valve 28. By switching the solenoid valve 23 the pressure in the pipe branch 27 is reduced, the quick-air valve 28 is adjusted, the compressed air escapes from the small space 11 through the manifold 32 and the pipe strut 18 into or out of the exhaust pipe 4 downstream of the pressure vessel 1. This prevents the air from entering the free space and thereby generates noise.

After the pressure in the small space 11 has dropped, the diaphragm 9 will be deflected and the orifice 30 will be exposed to the outlet exhaust pipe 4 when the compressed air escapes from the large space 10.
