Abstract

A valve 28 for rapid venting of air, which controls a secondary space 11 of a pressure vessel 1 communicating by means of a bypass line 32 with a discharge tube of outlet 4 through a tubular element 18 that performs the function of stiffening element, or strut in pressure vessel 1 or downstream of this vessel. At the point where the bypass tube 32 enters the discharge tube of outlet 4, the tube is equipped with an insert in the form of a Laval needle for the purpose of reducing the above- atmospheric pressure of the air in the bypass tube 32.

Description

Device for removing the noise of the control valve

Technical field

AA /

The present invention relates to a device for removing the noise of a control valve of a label or arch remover in a furnace device or container and silo.

BACKGROUND OF THE INVENTION

So far, these label removers, the essential part of which is a large space for collecting the working compressed air and a small space for the 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 escapes into the free space, causing noise exceeding the specified standards. So far, silencers mounted on this exhaust port have been used, reducing this noise by about 10%, which is low and does not comply with the standard.

SUMMARY OF THE INVENTION

According to the invention, the noise of this valve can be eliminated by supplying the outlet port of the quick bleed valve to which a special silencer is supplied, fed to a manifold duct which is connected to an exhaust exhaust pipe through which the compressed air is guided into place. its effect, i + € 10 and therefore the compressed air does not come into the surrounding environment at all and the noise is eliminated. The interconnecting pipe from the valve is connected to the outlet of the new devices by a pipe brace of the quick-vent exhaust pipe, at a passing pressure vessel, or in previously manufactured devices, this interconnecting pipe is connected to the outlet exhaust pipe downstream of the pressure vessel. A Lavala nozzle liner is located at the inlet of the manifold into the outlet exhaust pipe to reduce air overpressure in the manifold.

By means of the device according to the present invention, considerably better noise reduction parameters are achieved, there is no need for regular maintenance of the muffler, clogged with dirt, oil, dust and moisture.

BRIEF DESCRIPTION OF THE DRAWINGS

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

Examples

The pressure vessel 1 is provided with a flange 6 to which a lid 7 with a diaphragm 9, a sealing ring 12, a return spring support 16 and a rubber damper 15 is fastened. The diaphragm separates a large space 10 from a small space 11. of compressed air. By deflecting the diaphragm 9 with the sealing ring 12, the compressed air path is released from the large space 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 feed port 17 of

to the pressure vessel 1. Through the pipeline branch 27 ^{, it} proceeds to the quick-vent valve 28 with the exhaust port 29 and from there is led to the compressed air inlet 14 into the small space 11 at age 7. From the quick-vent valve 28 whether for new products by a pipe brace 18 through a pressure vessel 1 to an outlet exhaust pipe 4 or to an outlet pressure pipe 4 downstream of a pressure vessel

i. At the inlet of the manifold 32 into the exhaust outlet pipe 4, there is a Lavala nozzle 33 in the exhaust exhaust pipe 4, which reduces the air overpressure in the manifold 32. At its outlet end,

the exhaust pipe 4 is provided with a flange 19 connected to the inlet 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-release valve 28. By switching the solenoid valve 23, the pressure in the branch 27 is reduced, the quick-release valve 28 is adjusted. 18 into the exhaust outlet pipe 4 or into it beyond 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 is deflected and the orifice 30 is exposed to the exhaust outlet pipe 4 when the compressed air escapes from the large space 10.
