Abstract

1. Gate valve for shutting pipes, in the body (1) of which one or more stem (6) adjustable disks (4) are arranged where the disks (4) show, on the averse side of the stem (6), a rectangular outside contour being provided with protruding sealing surfaces (10) which cooperate with circular protruding sealing surfaces (9) in the body (1) of the gate valve and where the sealing surface (10) of the disk (4), on the side facing the stem (6), is formed by a circular surface and, on the other side, is limited, for the one, by the circumferential line of half a square whose edge length corresponds to the diameter of the largest circle of the circular surface, characterized by the fact that the sealing surface (10) of the disk (4), for the other, is limited on the other side by the circumferential line of the smaller circle of the circular surface and that inside the smaller circle no additional sealing surfaces are provided.

Description

Vynález řeší problém uložení zářičů kalifornium-252 formou schránky na spodní straně výsuvné tyče trezoru·The invention solves the problem of placing the californium-252 emitters in the form of a box on the underside of the retractable vault rod.

Dosud známé prostředky pro uložení zářičů kalifornia-252 byly provedeny jako skřínky s podložkami pro nasunutí zářičů· Tyto skříňky jsou zasunuty nebo vloženy v prostorách trezoru. Toto řešení zapříčiňuje nesnadnou manipulaci se zdroji záření·The californian-252 emitters known to date have been designed as lockers with shims for sliding the emitters. These lockers are inserted or inserted in the vault. This solution makes radiation sources difficult to handle ·

Výše uvedený nedostatek je odstraněn schránkou pro uložení zářičů kalifornia-252 podle vynálezu, jehož podstatou je to‘, že schránka je tvořena spojovacím elementem, jehož jeden konec je centricky připevněn к čelu výsuvné tyče a druhý konec je centricky připevněn к tělesu schránky· V tělese schránky je provedeno vybrání pro vložení vložky. Tato vložka je opatřena jednak výřezem a jednak alespoň jedním zahloubením pro uložení zářiče· Povrch výsuvné tyče a tělesa schránky je upraven osazením pro navlečení uzavírací manžety.The above drawback is remedied by a housing for accommodating California-252 emitters according to the invention, which consists in that the housing consists of a connecting element, one end of which is centrally attached to the front of the slide bar and the other end is centrally attached to the housing. a recess for inserting an insert is made. This insert is provided with a cut-out and at least one recess for receiving the radiator. The surface of the extension rod and the box body is provided with a shoulder for inserting the closing collar.

Konstrukčním řešením schránky podle vynálezu se podstatně usnadní manipulace se zářiči, jejich uložení je spolehlivé. Dále je zabezpečena možnost kontroly počtu zářičů. Při chybné manipulaci se zdrojem záření je omezena možnost jeho zapadnutí do nepřístupných míst. Konstrukční uspořádání vložky umožňuje vložení různých druhů zářičů o rozličných rozměrech.By designing the container according to the invention, the handling of the emitters is considerably facilitated and their placement is reliable. Furthermore, the possibility of controlling the number of emitters is ensured. Incorrect handling of the radiation source limits the possibility of its fitting into inaccessible places. The construction of the insert allows the insertion of different types of radiators of various dimensions.

Příklad provedení schránky pro uložení zářičů kalifornia-252 podle vynálezu je vyznačen na obr.1 a obr.2 · Obr.1 zachycuje schránku pro uložení zářičů v axonometrickém pohledu, obr.2 pak stejnou schránku v řezu.An exemplary embodiment of a California-252 radiator receptacle according to the invention is shown in Fig. 1 and Fig. 2. Fig. 1 shows the radiator receptacle in axonometric view, Fig. 2 shows the same receptacle in cross-section.

Schránka pro uložení zářičů kalifornia-252 je vytvořena tak, že jeden konec válcového spojovacího elementu j. je kolmo našroubován do středu čela výsuvné tyče 6 · Na druhý konec válcového spojovacího elementu 2 je centricky našroubováno válcovité těleso 2 schránky, ve kterém je provedeno vybrání 8 ·The housing for accommodating the California-252 radiators is designed such that one end of the cylindrical connecting element 1 is perpendicularly screwed into the center of the slide bar 6. ·

Vybrání 8 slouží pro vložení prstencovité vložky 2» která je opatřena jednak příčným výřezem 2 pro nasunutí vložky 2 a* spojovací element 2 a jednak určitým počtem zahloubení 2 Pro zářiče. Počet zahloubení i je roven počtu uchovávaných zářičů. Všechna zahloubení 2 jsou .provedena po obvodu fiktivní kružnice vyvrtáním. Povrch výsuvné tyče 6 a tělesa 2 schránky je upraven osazením £, na kterém je navlečena uzavírací manžeta £. Spojovací element 2» výsuvná tyč 6, těleso 2 schránky, vložka 2 a uzavírací manžeta £ jsou provedeny z polyetylénu.Recess 8 serves to receive the annular inserts 2 »which is equipped with both the transverse cut for insertion of the insert 2 and 2 * coupling element 2 and secondly a number of recesses 2 P ro emitter. The number of recesses i is equal to the number of stored emitters. All depressions 2 are carried out by drilling the circumference of the imaginary circle. The surface of the extension rod 6 and the container body 2 is provided with a shoulder 6 on which the closing sleeve 6 is threaded. The connecting element 2, the pull-out rod 6, the container body 2, the insert 2 and the closing sleeve 6 are made of polyethylene.

Uzavírací manžetou £ je prostor schránky uzavřen. Přístup к zářičům je umožněn přesunutím manžety £ do horní polohy v mezích, upravených osazením χ. Vložka 2 je kolem spojovacího elementu 1 otočná a výřez 9 umožňuje její snadnou výměnu.By means of the closing sleeve 8, the receptacle space is closed. Access to the radiators is enabled by moving the sleeve 6 to the upper position within the limits adjusted by the shoulder χ. 2 e j insert around the connecting element 1 and a rotatable notch 9 allows its easy replacement.
