DE102009035806A1 - Ventilating component i.e. floater-ventilating valve, for mounting on faeces container of mobile toilet system, has floater controlling spill over of container content, and ventilating body removed only by rotating thread towards container - Google Patents

Abstract

The component has a safety valve ensuring transport of waste to a closure of a faeces container, and a floater (F6) controlling spill over of faeces container content into a ventilating channel during extreme driving situation. A ventilating body is removed only by a rotating thread (F15) i.e. screw thread, towards the container. The component allows an actuator to be lifted by a threaded rod (F7) around 10 mm against a pressure spring (F2) by mechanical actuation function. The actuator is mounted on the rod. A floor screwing piece made of a rubber sealing lip (F13) seals an adapter plate.

Description

The practical experience with the EP 1 336 692 B1 required the redesign of a more advanced emergency evacuation bleed valve for future universal use on all mobile toilet systems on the market.

combined Safety and float vent valve with emergency equipotential bonding for installation and service friendly integration in waste disposal containers; (Faeces container will be called FB in future) suitable for all types and makes of different manufacturers.

The practical experience with the EP 1 336 692 B1 showed the need for a new design of a vent valve, which in the future can be used universally on all FB = waste containers on the market.

Because it is highly unhygienic, valve malfunctions at the built-in EP 1 336 692 B1 to perform and in the reasonableness of any service, without extreme dirt allowance can be demanded was, the new patented, external valve body, with its 3 compartment function = transport safety; Float function and emergency equipotential bonding as an external component for screwing into the FB floor of each FB designed.

at possibly occurring disturbances, this can be Unscrewed universal component by means of thread on the bottom of the FB and be replaced by a new one. In this approach would be the FB again immediately "functional" usable.

Should, for whatever reason, the desire exist for. B. only to seal renewal, the valve body continue to use Now there is the possibility of the component from the FB floor turn it out and in a jar with special cleaner hygienically clean. That would be the hygienic Condition created to perform a service allow.

Now For example, the seal set could be renewed, or a defective individual component to be renewed.

Of the The valve body repaired in this way can be replaced with a new seal provided, are screwed into the screw at the FB floor and is immediately functional again.

Because the experience has taught us that a discarded FB on the return transport, to the base system in the recreational vehicle, in the summer heat and vorgesetztter faulty handling, (The operating error is a thoughtless immediately after disposal tightly rotated drain plug) very quickly again can build an internal pressure in the FB, was the new vent valve designed so that when inserting the FB in the base system, the up there tightly closed safety valve uncompromising, even against the biasing pressure is opened by means of the spring F2.

Function - Description of the universal bleeder valve.

The In future, in all FB types, screw-in component with its 3 functions are, with incorporated FB in the, in the vehicle located base system, in the following

Functional state:

When inserting the FB into the base system, the actuator is moved 25 millimeters in front of the insertion end position (see 1 ).

These mechanical function actuation raises the actuator by means of the threaded rod F7 by 10 millimeters against a biasing member (compression spring) F2 at.

The actuator is completely mounted on a M8 threaded rod (see F7) and has a plastic plate at the top, F4 with M8 thread, as a sealing surface to the valve sealing lip (See 5 )

at Actuator actuation with a total of 10 millimeters stroke of the Actuator lifts the plastic plate F4 from the rubber sealing lip F5 off and is at the maximum technically feasible place directly below the FB roof the ventilation channel permanently free.

at multiple use of the toilet and slowly increasing Level of the FB approaches the content level more and more the float function point F6 in its rest position.

Increases the fill level z. B. by curves or strong braking over the rest of the float F6 addition, this increases with the level to the top and closes, if necessary, the ventilation duct briefly to a spill of sewage, in the venting channel to prevent.

The practice and test experience, especially on hot summer days, has shown us that on alpine pass rides on long serpentines the swimmer closes the venting duct slightly longer than during a normal cornering. In this time it may, although rare, in extraordinary, un favorable situations, by the permanent gas formation, with the internal decomposition process in the FB, particularly with high outside temperatures, come to that with patent EP 1 336692 B1 the valve can go into self-holding, by pressure build-up in the FB.

Out For this reason, the valve component was in addition to the revolutionary Change to serviceability, as to this Danger, the possible self-preservation, again constructive so seriously changed that an independent Patenting of this external component inevitable and was advisable.

At the Float was, at specially suitable position, a 4 millimeters Hole set F8 Functionally causing next

These 4 mm channel hole creates, with closed float, a time-limited potential equalization between the gassing FB and the venting channel F7 and thereby prevents the Self-holding of the float valve.

Now one could assume that then about these 4 millimeters Drilling the FB content, at full submersion of the float, perk enters the vent channel.

In the act runs through the swimmer, over this 4 mm hole at extreme slanting of the Vehicle a little liquid, but still not in the venting channel F7

The Valve component has a small compensation chamber also for the length of a long serpentine so much compensation room has to the accumulating liquid, which is not permanently pending to catch.

To Termination of the extreme curve, with tilt of the vehicle, when the float releases the vent again, the accumulated content, the compensation room, back to the total volume in the FB.

to Attachment of the component to the FB floor of the FB becomes a counterhold component F12 with external thread used.

to Sealing the FB bottom passage, becomes a rubber roof seal are used F11.

This Combination component F12 includes adding, constructive, already the room for receiving a displacement-willing rubber seal lip F13. as a further sealing point to the adapter plate

These called rubber sealing lip F13 provides the secure connection to the adapter plate the exhaust air forwarding to a modern Airmix ventilation system ago.

For the retrofitting of end - of - life vehicles is the responsibility of the manufacturer of the Universal ventilation components highly recommended to offer a plastic ring with internal thread in which a resistance wire is integrated. The retrofitting of mobile old toilet facilities with the innovative venting component then becomes very easy to be done.

By the FB floor is milled a hole with matching opening; then the part with the resistance wire is inserted and clean Edition, pressed from below and above; then it will be for 1 minute 12 Volt DC voltage placed on the resistance wire. After that the component fuses with the FB bottom and is tight. Now only the valve needs to be screwed in and the FB is ready for use.

Advantages of the invention

• 1 universal use in all FB waste container
• 2 Installation and service friendliness at its best level
• 3 Optimal technical basis due to the 3 compartment function.
• 4 In conjunction with the Lutz Airmix vacuum ventilation system will provide 100% odor free on all mobile toilets reached. From this overall concept can, justified, of a paradigm shift be spoken in the mobile toilet area.
