Definitions

  • the invention relates to a valve arrangement for containers for the production, treatment and / or storage of liquids, in particular wine.
  • a low-pressure process is proposed, which is made possible by the use of an arranged on the container pressure relief valve and preferably at the same time a vacuum valve.
  • the maximum pressure reached until the opening of the pressure relief valve is about 0.5 bar, while the maximum negative pressure reached until the opening of the vacuum valve is only about 0.005 bar.
  • delicate, thin-walled stainless steel containers are not damaged. It is considered that such stainless steel containers are much more sensitive to a vacuum than to overpressure.
  • the pipe system for the valves is connected in the area of the highest point of the vessel to ensure that there is a connection to the headspace over the contents, but not the contents themselves.
  • the Pressure relief valve is assigned to a pressure gauge with a scale ranging from 0 to 0.5 bar scale.
  • the pressure relief valve is a spring-loaded seat valve.
  • the spring preload which determines the height of the opening pressure of the valve, can advantageously be adjusted via a threaded sleeve. It is particularly advantageous if the lower region of the valve, where gas flows out of the container when the valve is opened, is surrounded by a liquid reservoir, for example a stationary cylinder of preferably transparent material.
  • the stand cylinder is preferably made of glass or acrylic glass.
  • the cylinder defines an upwardly open annulus, which can be filled with a liquid.
  • the cylinder is sealingly clamped to a flange which forms the bottom of the reservoir by means of an O-ring.
  • In the lower region of the valve housing at least one opening is provided, which leads to the inner region of the valve above the valve seat. This access opening should be covered by a filled liquid level.
  • the escaping at excess pressure gases escape through the liquid.
  • the resulting bubbles are on the one hand visually perceptible, on the other hand, a clucking noise occurs, which is acoustically perceptible.
  • the escape of gases from the container is thus in a simple manner and also from a distance - for larger containers several meters - visually and acoustically signaled.
  • the liquid used When using a suitable liquid, a chemical reaction with an indicator effect may occur.
  • the liquid used also enters the interior of the valve housing and surrounds the valve body. Nevertheless, the liquid can not enter the interior of the tank via the valve since the valve seat has a conical seat which only opens when the pressure is correspondingly high, and the outflowing gas then prevents the liquid from entering.
  • the valve further comprises an actuating button, which is directly connected to the valve body and from the outside by lifting a manual pressure release of the tank allows.
  • a manual pressure release is performed, for example, when the tank is to be opened, because he should then be pressure-free.
  • the manometer can be monitored when the pressure equalization has taken place.
  • the valve comprising the pressure relief valve may still have a shut-off valve. This is preferably designed as a ball valve or ball valve.
  • the tank can be charged with CO 2 via this tap. It is also possible to pass liquid additives into the tank. Furthermore, a level indicator can be connected.
  • a negative pressure valve is provided in addition to the pressure relief valve.
  • This has an opening pressure of about 0.005 bar.
  • This very low level of vacuum is used as an upper limit to prevent pressure damage to the tank.
  • a negative pressure per se does not favorably support the fermentation process or similar processes.
  • the vacuum control is only intended to compensate for expansion and contraction during temperature fluctuations or air pressure fluctuations. It is particularly important when removing liquid from the tank, that a ventilation is ensured, which is preferably done automatically by the use of the vacuum valve. It was previously known to provide a manually operated shut-off mechanism on the top of the tank, which, however, had to be opened before emptying or removal of the liquid from the tank.
  • the vacuum valve has a valve stem, which is sealed at the top by a patch on the valve housing silicone cap against the ingress of dirt particles.
  • the vacuum valve is preferably rigidly connected to the tank via a flange connection.
  • the overpressure part of the valve is adjustable Threaded connection connected to the vacuum part. In this way, the inclination of the overpressure part can be varied so that an operator can easily optically monitor the pressure gauge and the function of the overpressure valve from a ground-level position. This is of particular interest for large tanks, which may have heights of several meters.
  • the application of the valve system according to the invention is not limited to large tanks.
  • the field of application ranges from small tanks or small tanks with volumes in the range of 100 liters to large tanks with capacities in the range of 1 million liters.
  • the illustrated embodiment covers all purposes, i. the valve device does not scale with the tank size.
  • the pressure relief valve can be used up to a discharge rate of about 30,000 l / h.
  • the valve assembly shown in the drawing consists essentially of a three tees 10, 12, 14 comprising a pipe system that connects a vacuum valve 16 and a pressure relief valve 18 to the top of a container, not shown.
  • the T-piece 10 has a conical socket 20 which is fastened by means of the nut 22 to a corresponding counterpart on the container.
  • the T-pieces 10 and 12 are connected to each other, so that the T-piece 12 can be pivoted relative to the T-piece 10, for example, the pressure gauge 24, which indicates an overpressure in the container to be able to read better from a certain position.
  • a ball valve 26 is arranged, which can be opened to pressurize the container via a hose 28, for example, with CO 2 gas.
  • the pressure relief valve 18 is in Fig. 2 shown in more detail.
  • the valve 18 is designed as a seat valve, with a cone valve body 30 which is pressed by means of a spring 32 against a valve seat in the housing of the valve 18.
  • the bias of the spring 32 and thus the overpressure at which the valve opens, can be changed via a threaded cover 34.
  • the valve housing has a number of openings 36 through which gas can flow when opening the valve.
  • the openings 36 are surrounded by a liquid reservoir that is formed by a flange bottom 38 and an acrylic glass cylinder 40.
  • An O-ring 42 arranged in a circumferential groove of the flange bottom 38 ensures a frictional and liquid-tight fit of the cylinder 40 on the flange bottom 38.
  • a ball handle 44 is connected via a rod 46 to the valve body 30 and allows by lifting a manual pressure release of the container.
