Abstract

Изобретение относится к машиностроению, а именно к устройствам для соединения гибких шлангов с жесткими элементами.Соединение ниппеля со шлангом содержит втулку (8) с внутренней резьбой (7), в которую ввинчен ниппель (1), выполненный трехступенчатым, одна ступень - с резьбой и две другие - с лысками с четырех сторон. Конец ниппеля (1) выполнен в виде сферического буртика, жестко вставленного в шланг (15). Во втулке (8) по кругам выполнены три ряда резьбовых отверстий, в которых установлены элементы обжатия (11) с шестигранной внутренней головкой. В каждом ряду выполнены по четыре радиальных резьбовых отверстий (10).The invention relates to mechanical engineering, and in particular to devices for connecting flexible hoses with rigid elements. The connection of the nipple to the hose contains a sleeve (8) with an internal thread (7), into which a nipple (1) is screwed, made in three stages, one stage with a thread and the other two - with flats on four sides. The end of the nipple (1) is made in the form of a spherical collar rigidly inserted into the hose (15). Three rows of threaded holes are made in the sleeve (8) in circles, in which compression elements (11) with a hexagonal internal head are installed. Four radial threaded holes (10) are made in each row.

Description

Invenţia se referă la industria construcţiilor de maşini, şi anume la dispozitivele de îmbinare a furtunurilor flexibile cu elementele rigide. The invention relates to the machine building industry, namely to devices for connecting flexible hoses to rigid elements.

Se cunoaşte o îmbinare a furtunului de presiune înaltă, care conţine o bucşă şi două rânduri de găuri radiale filetate deplasate unul faţă de altul cu 45º, în găuri fiind înşurubate şuruburi cu suprafaţa de contact sferică, un capăt al niplului este cilindric cu filet, iar celălalt capăt este conic, şi pe el este amplasată o treaptă [1]. A high-pressure hose joint is known, which contains a bushing and two rows of radial threaded holes offset from each other by 45º, screws with a spherical contact surface being screwed into the holes, one end of the nipple is cylindrical with a thread, and the other end is conical, and a step is placed on it [1].

Dezavantajul soluţiei constă în aceea că îmbinarea nu este eficace, astfel încât este imposibilă strângerea furtunului la diametrul exterior al niplului cu suprafeţele sferice de contact ale şuruburilor. The disadvantage of the solution is that the joint is not effective, so it is impossible to tighten the hose to the outer diameter of the nipple with the spherical contact surfaces of the screws.

Problema pe care o rezolvă invenţia este de a majora siguranţa îmbinării niplului cu furtunul în zona strângerii şi fixării furtunului, de a asigura montarea şi demontarea construcţiei. The problem solved by the invention is to increase the safety of the nipple-hose connection in the area of tightening and fixing the hose, to ensure the assembly and disassembly of the construction.

Dispozitivul, conform invenţiei, înlătură dezavantajul menţionat mai sus prin aceea că conţine o bucşă cu filet interior, în care este înşurubat niplul executat în trei trepte, una - filetată şi celelalte două - executate cu faţete din patru părţi. Capătul niplului este executat ca o bordură sferică, introdusă rigid în furtun. În bucşă pe cercuri sunt executate trei rânduri de găuri filetate, în care sunt instalate elementele de strângere cu cap hexagonal interior. În fiecare rând sunt executate câte patru găuri radiale filetate. Faţetele treptelor niplului sunt executate paralele sau neparalele una faţă de alta. The device, according to the invention, eliminates the above-mentioned disadvantage by containing a sleeve with internal thread, into which the nipple made in three steps is screwed, one - threaded and the other two - made with four-sided facets. The end of the nipple is made as a spherical rim, rigidly inserted into the hose. In the sleeve on the circles are made three rows of threaded holes, in which the tightening elements with an internal hexagonal head are installed. In each row are made four radial threaded holes. The facets of the nipple steps are made parallel or non-parallel to each other.

Rezultatul invenţiei constă în strângerea furtunului cu şuruburi pe niplu cu înveliş metalic fără cauciuc şi cu furtunul interior, mărirea suprafeţei de strângere şi realizarea îmbinării montabile şi demontabile. The result of the invention consists in tightening the hose with screws on the nipple with a metal coating without rubber and with the inner hose, increasing the tightening surface and creating a mountable and dismountable joint.

Invenţia se explică prin desenele din fig. 1-4, care reprezintă: The invention is explained by the drawings in Fig. 1-4, which represent:

fig.1 - vedere generală cu secţiune parţială; fig.1 - general view with partial section;

fig.2 - niplu cu filet; fig.2 - threaded nipple;

fig.3 - secţiunea A-A din fig. 1; Fig. 3 - section A-A of Fig. 1;

fig.4 - secţiunea B-B din fig. 1. fig.4 - section B-B from fig. 1.

Îmbinarea niplului cu furtunul conţine o bucşă 8 cu filet interior 7, în care este înşurubat niplul 1 executat în trei trepte, una - filetată şi celelalte două 2, 3 - executate cu faţete 4, 5 din patru părţi, suprafaţa 9, o gaură 13 şi capătul drept 14. Capătul niplului 1 este executat ca o bordură sferică 6, introdusă rigid în furtunul 15. În bucşa 8 pe cercuri sunt executate trei rânduri de găuri filetate, în care sunt instalate elementele de strângere 11 cu cap hexagonal interior 12. În fiecare rând sunt executate câte patru găuri radiale filetate 10. The nipple-hose connection contains a bushing 8 with an internal thread 7, into which the nipple 1 is screwed, made in three stages, one - threaded and the other two 2, 3 - made with facets 4, 5 from four sides, surface 9, a hole 13 and a straight end 14. The end of the nipple 1 is made as a spherical rim 6, rigidly inserted into the hose 15. In the bushing 8, three rows of threaded holes are made on the circles, in which the clamping elements 11 with an internal hexagonal head 12 are installed. In each row, four radial threaded holes 10 are made.

Îmbinarea niplului cu furtunul funcţionează în felul următor. The nipple-to-hose connection works as follows.

Niplul 1 înşurubat rigid pe filetul interior 7 al bucşei 8 prin bordura sferică 6 se introduce în furtunul 15, urmărind prin găurile radiale filetate 10 să fie situat corect. Se fixează cu elementele de strângere 11 de faţetele 4, 5. The nipple 1, screwed rigidly onto the internal thread 7 of the bushing 8 through the spherical rim 6, is inserted into the hose 15, ensuring that it is correctly positioned through the threaded radial holes 10. It is fixed with the clamping elements 11 to the facets 4, 5.
