Description

The subject of the invention is a device that is convenient and safe inserting short tubular pieces of rubber, especially hose valves for self-donors, in hard-to-reach holes.

In the drawing is an exemplary embodiment of the subject matter of the invention Device explained, which is intended to be a ίο lip valve in the wall of a To use pressure medium container surrounded liquid container of a self-donor and to secure the valve after insertion by pressing in a plug. in the single show

The self-donor consists essentially (Fig. 1) of a liquid container A. a surrounding pressure medium container A ¹ and a hood A ² covering both parts. In the jacket of the liquid container A there is a hole a? provided, in front of which there is an opening a * in the jacket of the pressure medium container A ¹ , which can be closed by a screw plug, not shown. The hole a ^s is used to receive a lip valve B (Fig. 2), which is designed as a short tubular rubber piece with sealing lips b ¹ and a flange b ² . To insert the valve B into the hole a ^s , which is difficult to access due to its position behind the wall of the pressure medium container A ¹ , this serves the purpose of

Subject of the invention forming device (Fig. 3 et seq.). This ordered from a bolt C provided ^{with a bore c 1 over} most of its length, a pin D guided in the bore c ¹ and a spring E, which is also arranged in the bore c ¹ . The pin D is provided at the front with a stepped part d ¹ that fits into the cavity of the valve B and at its rear end with a transverse pin rf ^{2 protruding through slots c 2 of} the bolt C , by means of which it counteracts the action of the spring E can be pulled into the bolt C. In the front limit position of the pin D, d \ in which the transverse pin rf ² rests on the front end of the slots c ² , the stepped part d ¹ protrudes at one end of the bolt C from the bore c ¹ . At its other end, the bolt C is provided with a threaded hole c ³ .

A pierced plug F (Fig. 7 to 10) serves to secure the used valve B, the front f with a thickening is provided ¹ and further back with a flange f ~, to which a in the threaded bore c ^s a suitable threaded pin f ^s connects.

When the valve B is inserted into the hole a ^s , the valve is first ^{rf via the part protruding from the bore c 1 of} the bolt C. ^{1 of} the pin D, d ¹ and then inserted into the hole a ^s by means of the bolt C pushed through the opening a ^l (Fig. 4). Then the pin D ₁ rf. ¹ against the action of the spring E in the bolt C pulled, the pin C b by a pressure applied to it against the flange pressed ² and the valve B is thus while the portion d ¹ drawn out of it, in the hole a ³ is held (Fig. 5). Fig. 6 shows the self-donor with the inserted valve in the state that exists after the pin D ₁ d ¹ is pulled out of the valve. Then the bolt C is pulled out of the opening α ⁴ , then the plug F with its threaded pin / ^{8 is} screwed into the bore c ^{s of} the bolt C (Fig. 8), the bolt is pushed through the opening a ¹ and 5 " is pressed into valve B (fig. 9), then the bolt C is unscrewed from the plug F and withdrawn, completing the process of inserting and securing valve B (fig. 10).

When removing the valve B from the opening a ³ , a coupling between the bolt and the plug F is first produced by screwing the part of the bolt C provided with the threaded hole c ^s onto the threaded pin f ^s and then the plug F is pulled out by means of the bolt C. at the same time the valve is pulled out with it.
