Valve for controlling the discharge of liquid or vapor from a container

The invention relates to a valve for controlling the output of liquid or vapor from a container in which the latter are contained under pressure.

A number of gases are usually stored in liquefied form under pressure in containers that are normally contain the liquefied gas and the gas itself side by side. Under certain circumstances it is desirable to have the material in the container, for example a liquefied petroleum gas such as propane or a gas serving as a coolant, such as Genetron or a fluorocarbon, either in the liquid or in the vapor phase, but not as a mixture of the two phases

refer to.

For this purpose there are already some valves with an outlet or several outlets known, of which those with only one outlet are basically easier to handle. but generally consist of so many individual parts, that their manufacture and maintenance are difficult and their reliability is poor.

The object of the invention is therefore to create a simple constructed such valve with only one outlet, the consists of only a few parts and in particular has only a few moving parts and is therefore produced in a simple manner and can be maintained and works reliably.

The invention relates to a valve for controlling the Dispensing liquid or vapor from a container containing a liquefied gas and the gas itself under pressure. The valve is characterized in that it has a housing with "an outlet channel in its upper part which is in the open Connection with a first chamber and several Inlets for steam or liquid to a direct arranged over these and in open connection with them standing second chamber in its lower part, a the first and second chambers connecting passageway for flowable media, a shut-off valve between the first

Chamber and this passage and a rotatable multi-carriage valve in the second chamber with such dimensions that it., when rotated, selectively certain feeds for Connects vapor or liquid to the passage.

In a preferred embodiment of the valve of the invention, the housing is designed so that it fits into the upper End of a container filled with a liquefied gas can be used, and in its lower end trending feed uEigaa stand within of the container in offesisr ¥ @ rbind with each other. At least One of these feeds ends in the steam space in the container and is used to feed tok steam into the second chamber, and at least one further inlet is designed so that it has an immersion tube extending to the bottom of the container extends, is capable of receiving, and serves to supply liquid to the second chamber. The reusable tap is from the side is inserted into the housing and formed so that when it is rotated, one of these leads with the passage for Flowable Kedien connects so that depending on the position this tap either vapor or liquid get into the passage. At the top of the passage

109840/0210 ^ ■ _Bm

there is a valve seat. A chamber above the entrance :; away connects this init the outlet channel, which with the Chamber is in open communication. By means of a valve controlled closure part, which is on the valve seat can be pressed, the connection between the passage way and the second chamber opened or closed. Outside the housing there is an ale pointer on the multi-way valve trained handle attached by which the tap can be turned.

In the drawings is

Figure 1 is a vertical section through a valve according to the invention along the line 1-1 of Figure 2, wherein the representation in Figure 1 differs from that in Figure 2 insofar as the pointer in vertical Position shown 1st, and

FIG. 2 is an elevation of the valve of FIG.

As can be seen from Figure 1, the housing 1 has a downwardly extending part 2 with an external thread 3 for Screwing the valve into the top of a container containing a liquid and a gas under pressure on. In the preferred embodiment shown in the drawing of a valve according to the invention in the lower end 2 of the housing two feeds, viz

a feed for steam 4 and a feed for liquid 5. Of course, several steam feeds and Liquid feeds are provided. However, this complicates the structure of the valve and its operation, so that the arrangement of only one feed for steam and liquid is preferred.

The steam supply 4 is in open communication with the steam space in the container. The liquid supply 5 can be connected either by threading or by means of a snap connection to an immersion tube 6, which extends right up to the bottom of the container and below the surface of the liquid contained therein. The upper ends of the feed lines 4 and 5 are in open communication with a chamber 7, which in turn is in open communication with a passage for flowable media 8 ?. The passage 8, in turn, can, as can best be seen from FIG. S, borrowed. with a chamber 9 * which is in open communication with the outlet channel 10, are connected. The passageway 8 has a top valve seat 43 which can be brought into engagement with a valve holder 11 and the seal therein used 12, no that the upper end of the passage path is sealed. 8

The seal 12 consists of a tough plastic that is sufficiently resilient on the one hand. iat to seal around the upper end of the passage way 8, L \\ d on the other hand the stresses to which this part dna valve lst constantly exposed can withstand. ₄ The holder 11 is moved into the desired position above the valve seat 42 by means of a flexible membrane 1? Which can be made of metal and is arranged in the chamber 9. The crane 13 is held by means of a cap 14 screwed into the upper part of the kiss 1 against a seat Vo in the interior of the housing 1. A valve stem 17, the lower end 18 of which is preferably convex and is in single engagement with the upper surface of the membrane 13, is screwed into the cap 14. An oriff 19 is attached to the valve stem, the rotation of which guides the valve stem downwards or upwards, so that the membrane is correspondingly bent. A spring 20 arranged in the chamber 9 around the lower part of the holder 11 rests at 21 on the Biden dieeer chamber 9 and presses from below against the flange i? the bracket 11.

When the handle 19 is rotated in the opposite direction, the stem 17 moves upward, the contact between the diaphragm 13 and the holder 11 is released, and the spring 20 urges the holder 11 out of engagement with the valve seat 43 / so that Oas or liquid can flow from the passage 8 into the chamber. The contact between the passage 8 and the chamber 9 also occurred in a manner other than that described, ie the type of this seal is not of essential importance. Since the chamber 9 is in open communication with the outlet channel 10, liquid which reaches the chamber 9 from the passage 6 flows further through the outlet channel 10.

In order to control the flow of liquid or gas from the feed lines 4 and 5 through the chamber 7, a rotatable multi-way valve 23 with an at 24 is located in the passage 8

in the multi-way valve S3 are dimensioned and arranged so that they selectively one of the feeders 4 or 5 with the Durohtrittsweg 8 connect «when the tap is turned. That is to say, the passage 8, the inlets 4 and 5 and the inlet and outlet openings in the multi-way valve 23 are dimensioned in such a way and with respect to one another arranged so that when the valve is turned between two different positions, one of the outlet openings enables the passage of liquid or Oae into the main passage 8, while only one of the inlet openings opens allows liquid or gas to enter the cavity of the tap. In the execution form shown in the drawing is the inlet opening 27 for the fluid supply 5 complementary to the outlet opening 25 and axially in alignment arranged with this arranged inlet opening. The latter two openings are designed and arranged so that they axially in alignment with the Durohtrittsweg 8 and the steam supply 4 to be rotated. When the tap 23 is turned so that the Durohtrittsweg 8 and these two openings are in alignment lie with each other, steam from the supply 4 through the tap 23 in the passage 8 and from this through the Chamber 9 and the outlet channel 10 arrive, provided that the holder 11 does not engage with the valve seat 43 stands. The inlet opening 27 is then not in alignment with the liquid feed 5, so that no liquid through the tap 23 can flow. When the tap in the alternative

This valve consists of a lateral port set y with a bore 55 and a through-passage 56 through which the steam supply h is connected to the bore. A valve seat 57 engages with an element 38 which in turn engages with a valve disk 39 against which one end of a spring 4θ rests. The other end of the spring engages shoulder 41 of an apertured plug 42 screwed into bore 55. The spring 4o holds the valve disk 59 and

Manufacture and maintenance of the valve described in the invention are simple, and the valve can be opened or closed by simply turning a handwheel and simply turning a pot between two alternative stalls so that neither liquid or steam emerges from the container.

That valve according to the Erfiraöuns came to be modified in various ways. For example, the outlet openings 25 and 26 in the reusable belt 23 can be combined to form a socket which blocks out the openings, as long as no material can get into the tap from one of the feeders. File, the function of the 'valve is not disturbed * by the fact that both. Outlet openings at the same time with the Burolsfcrlttsweg 8 or with each other in connection. Steam feed 4 and liquid feed 5 can also be exchanged, and, as mentioned above, several power feeds and several plush feeds with corresponding openings in the multi- tap can be provided.
