The invention relates to a sealing device by means of which the insulation packed in several pressure containers is applied to the object to be sealed by means of a nozzle device arranged at the end of the supply pipe.

For fast and efficient sealing and sealing, pressurized joint insulation or foam is generally used, which is pressed into the joints and crevices to be sealed by pressure and which, as a self-expanding, effectively seals and fills all possible gaps, crevices and openings. For small users, the insulation is packaged in aerosol bottles through whose nozzles the insulation is directed to the target. A pressure bottle has been developed for professional use, from which the insulating material is directed to the target by means of sufficiently long hoses and nozzles at their ends. However, the capacity of the aerosol bottle is limited and the use of a pressure bottle is often cumbersome. The object of the invention is to combine the advantages of aerosol bottles for small use and pressure vessels for large use and to provide a sealing device suitable for professional use and inexpensive.

The device according to the invention is characterized in that the pressure vessels are connected to a common supply pipe provided with a connection for each pressure vessel.

To simplify the use of the device, the connections of the supply pipe can be connected to each pressure vessel with quick locks, alternatively a simple hose clamp can be used for each connection as a lock.

Thus, with such a device, several disposable aerosol tanks can be connected together, whereby the capacity of the device is considerably increased, but the disadvantages caused by the larger pressure cylinders 2,67740 can be overcome. Large bottles are cumbersome to handle and are not disposable items but must be returned for refilling after use.

Preferably, in the device according to the invention, the pressure containers are packed in a series of several bottles, thus forming a packaging cassette.

In a preferred embodiment, the valves of the pressure vessels can be opened simultaneously by pressing the supply pipe or folding sideways relative to the pressure vessel.

It is also advantageous to shape the supply pipe so that it can be locked in the open position of the valves, whereby the device is completely ready for use without additional measures and the operation of the device is then controlled only by a supply nozzle device, preferably a sealing gun. For ease of use, pressure vessels equipped with risers are preferably used. In this way, the tanks can be placed in a standing position and a supply pipe can be connected to these tanks. If risers are not used, the tanks must be placed upside down to allow the sealant to discharge.

In a preferred embodiment, the connections are articulated to the supply pipe. With such an arrangement, the valves of all the tanks can be easily opened simultaneously by pressing or bending down the supply pipe and the associated connections.

The invention will be described in more detail with reference to the accompanying drawings, of which

Figure 1 shows a preferred embodiment of the invention, Figure 2 shows another preferred embodiment seen from above, and 67740 Figure 3 shows a detail of Figure 2, Figure 4 shows a preferred connection according to the invention, Figure 5 shows a partial section of the connection according to Figure 4, and Figure 6 shows a practical application of the invention.

In the embodiment shown in Figure 1, the device consists of six pressure vessels 1 arranged in succession, which are provided with a riser, so that the vessels 1 can be placed in an upright position. Each tank 1 is connected to the common supply pipe 2 of the tanks by placing the valve stem 8 of the tank 1 in connection parts 3 formed for the stem of the supply pipe 2. In the case according to Figure 1 the connection 3 is locked to the valve with connections 3 for the spindles of the tanks made at suitable points. A flexible hose 4 is connected to the free end of the supply pipe 2, which in turn is provided at the free end with a gun device 5 by which the discharging sealant is guided to the target using the trigger of the gun.

The device shown in Fig. 1 operates in such a way that the supply pipe 2 is pressed down towards the tanks, whereby the valves of the tanks open and the substance is discharged from the tank into the supply pipe 2 and its connecting hose 4.

Figure 2 shows another embodiment of the invention. This device also uses six pressure vessels 1 but they are grouped in adjacent rows of two to three cylinders. The supply pipe 2 is thus divided into two parts for both 4 67740 rows of tanks and the supply pipe parts 2 are connected to each other by a flexible hose part 6. The other part of the supply pipe 2 is connected to the connection hose 4 and its gun device 5.

In the case shown in Figure 2, there is a further difference to the device shown in Figure 1. It is important for the operation of the device that all the valves in the tank be opened at the same time. In the embodiment shown in Fig. 2, both parts of the supply pipe 2 are connected to the spindles 8 of the containers 1 by means of connecting parts 3 fixed by a joint 7 of the supply pipes 2. The operation of the valve 8 is such that when the valve stem is bent, the valve opens. Thus, the valves can be opened simply by pushing the parts of the supply pipe 2 downwards, whereby the valve stems 8 turn to the side and the valve opens and the sealant is discharged from the tanks 1 through the articulated connections 3 into the supply pipe 2.

Figures 4 and 5 show a practical connection method. The connecting parts 3 of the supply pipe 2 are provided with external threads. A sleeve-like body 9 is intended to be connected to this, the internal threads of which correspond to the external threads of the connection 3. At the bottom of the sleeve there is a sealing body 11, which is preferably at least partially elastic material, e.g. rubber, plastic or the like. The seal body 11 is further provided with a through hole. The sealing piece 11 is placed on the bottom of the sleeve, which has a hole 10 in the bottom, whereby the seal 11, when installed, is positioned so that its through hole rests at the bottom hole 10.

The sleeve 9 is placed on the connection 3 and the valve stem 8 of the pressure vessel is inserted through the bottom hole 10 and the through hole of the seal 11 into the channel formed by the connection 3. The end sleeve 9 is then tightened by screwing it onto the connection 3, whereby the seal 11 is pressed between the bottom of the sleeve and the end surfaces of the connection 3 67740 while expanding. The seal 11 presses strongly against the mandrel 8 and against the side walls of the sleeve 9, providing an effective seal.

To facilitate rotation of the sleeve, an intermediate ring is made between the end face of the connection 3 and the seal 11, which is made of such materials that the friction between the intermediate ring and the end surface and the intermediate ring and the seal is so small that sliding between these pieces is possible. The spacer ring 12 is preferably plastic.

In order to facilitate the rotation of the sleeve 9, it can be shaped in a suitable manner or provided with, for example, the projecting pins according to Figures 4 and 5.

For ease of use, the supply pipe 2 can also be shaped so that it can be locked in the valve-opening position. In this case, for example, the previous hooks or a similar form lock can be used so that the valves remain open during operation.

The device according to the invention is simple to clean after use. For example, a gun device 5 containing a cleaning agent can be removed from the pipe system and replaced with a material container containing a cleaning agent, through which the cleaning agent is pressed into the pipes and the cleaning agent is discharged through the connectors 3 from which the pressure containers have been removed. Because the device is very simple and consists of simple piping systems, cleaning is easy and no clogging can occur.

It is also advantageous from the point of view of use that the pressure vessels 1 can be packed already in the manufacturing stage in suitable units, i.e. cassettes, which contain a certain number of containers either in one row or in a suitable formation. In this case, the supply pipe is naturally shaped accordingly. It is, of course, possible to connect several of the above-mentioned cassettes together by means of a connecting piece. Figures 1 and 2 show a series of six tanks, but it is clear that the invention is not limited to any given number of tanks but can be varied as needed.

Figure 6 shows a practical application of the invention.

Here, two parts of the supply line 2 are used, which are connected by a hose bend 6. The supply pipes 2 are each provided with five connecting parts according to Figures 4 and 5, which point somewhat to the side, i.e. not directly upwards.

The parts of the supply pipe are placed in a support frame 13 provided with a carrying handle 14 and adjustable support racks 15 for the pressure bottles 15. The support racks 15 for the bottles are turned to the initial position, i.e. slightly outwards from the support frame by means of a stop plate. A pressure bottle 1 is inserted into each support ring of the support bracket 15 for the pressure cylinder, the valve stem 8 of which is inserted into the connection 3 as described above.

Once all the bottles are in place and the connections attached to the support racks 15 are turned to the up position. In this case, the mandrels 8 of the pressure bottles bend and the valve opens and the contents of the pressure vessel can be discharged into the supply pipe 2 and further from there to the connecting pipe. The presented application is simple and easy to use and move from one place to another.
