DE1795530U - SPINDLE LESS WATER OR AIR VALVE, IN PARTICULAR FOR PIT AND THE LIKE. INDUSTRIAL COMPANIES. - Google Patents

Description

Spindle-less water or air valve, especially for pit and the like. Industrial companies.

Spindleless valves for water and air have already become known, by adhering to the known valves provided with spindle and handwheel Disadvantages due to their bulkiness and protruding parts as well as difficult Handling occur should be eliminated, however, these valves have more or more less the disadvantage that they are for use in rough pits or other operations are not easy enough and too sensitive or even to open and close them a larger rotational movement of the valve body carrying the extraction hose or Housing require what is unfavorable to the extraction hose due to excessive stress the same effect.

According to the present innovation, the disadvantages outlined are completely eliminated. It consists essentially of one with a central through opening provided ball insert to be connected to the relevant water or air supply line, around which the outlet opening provided with angled angled and the removal tube bearing valve housing is rotatable to a limited extent. By means of the around the ball insert and adjustable housing is a coarse and fine adjustment of the water or. Air outlet, depending on requirements, possible.

According to the innovation, the valve has the further advantage of being small Space requirements and, with simple and secure sealing of the moving parts against each other, of the great wet or. Air passage with a short, robust design that does not protrude and has bulky parts. This causes damage to the valve during operation excluded by breaking off bulky parts.

The valve is equally suitable for withdrawing water as well from air and can be used in many other ways as well as in mining operations.

The drawing shows an example of an embodiment of the innovation shown. They show: Fig. 1 a view of the leech insert with a section through the actual valve housing, Fig. 2 a section through the valve housing without Insert body and hose connection, Fig. 3, an individual part in view.

The valve consists of one with a spherical head 1 provided insert body 'with a centrally running Durchgangsof: Mug 3 those in Eopfteil 1 in a certain Angle opens laterally. The ball insert body 1, 2 rests in a short squat valve housing 4 and is in this- sem by a ring 5 screwed into the front part hold and with a sealing ring 6 against the housing wall dung sealed The rotary movement of the housing 4 to the Kugeleineatz 1, 2g by means of thread attachment 7 with assignment a lock nut 8 firmly with the relevant water or. - Air supply line can be connected is through a pin 9 which engages in a corresponding groove 10 of the insert body, limited. The rotation limitation of the housing can also be achieved by some other suitable device.

The housing 4 is provided with an angled extension 11 into which a connecting piece 12 is screwed, the passage opening 13 of which coincides with the passage opening 3 of the head 1 when the valve is open. The connecting piece 12 is provided at the outer end with a threaded extension 14 for connecting the extraction hose, and lies at the inner end by means of a groove closing to the head 1 where- in the case of the required sealing additionally by a but sealing ring 15 takes place. In the area of the head 1 the housing 4 is opposite the extension 19 with an outlet recess 17 provided to accommodate a correspondingly thrown Dzuckstüekes 16p that at the same time the insert body 1, 2 holds in place. The pressure and sealing piece 16 is inserted into the housing 4 before the insert body is installed. The main inventive feature of the new valve lies in the Possibility of opening and closing the valve by opening slight twisting of the valve housing in relation to the fixed standing Xugel insert body and the adjustable coarse and Fine adjustment of the water or Air passage with a short, compact design that withstands the impact of rock masses and other objects without damage, the individual sealing and holding devices of the two mutually rotatable parts also being designed in some other suitable manner.

S c htz a nsprc he: 1. Spindleless water or air valve, in particular for mining and similar industrial operations, characterized in that a rotatably arranged in a valve housing (4) neter insert body (2) a spherical head (1)

Claims (4)

has, in a groove at the output (11) of the hous @ es screwed hose connector (12) with assignment of a sealing ring (15) sits tightly, and the central passage opening (3) in the insert body (2) opens out laterally in the head piece (1) in such a way that it is connected to the passage opening (13) of the connecting piece at a certain angle to the center line of the insert (12) collapses when the valve is open by rotating the housing accordingly (4) the passage, however, more or less to the coarse or. Fine adjustment open or can be closed completely without detrimental stress on the connected Extraction hose. 2. Spindleless water or air valve according to claim 2, characterized that the insert body (1, 2) through a front screw-in ring (5) in the housing (4) held and sealed against the housing wall by a sealing ring (6) is. 3. Spindleless water or air valve make claims 1 and 2, characterized in that the head piece (t) of the insert body (2) by a in the housing (4) inserted pressure piece (16) made of a suitable, primarily flexible Material is pressed firmly onto its seat (12). 4. Spindleless water or air valve according to claims 1 to 3, characterized in that the rotatability of the housing (4) opposite the fixed to the supply line of the housing (4) gee connected insert body (1, 2) is limited by a limiting pin (9) or in some other way in order to prevent Überdreljen.
