Description

The invention relates to the construction, in particular to the sanitary equipment of buildings, and can be used in the device of sewer cleanings and revisions made of polymeric materials.

Cleaning and revisions are usually installed on straight-line horizontal and vertical sections of sewer pipelines, as well as near their turns. Modern sewer systems and networks are equipped with cleaners and revisions made of polymeric materials using straight pipes, bends, oblique and straight tees with sockets equipped with an elastic seal and a plug (Volkov V.A. Plumbing. - M .: Astrel: ACT, 2006 . - S.185-186).

Such cleansing and revisions are now prevailing, especially in new and reconstructed buildings for various purposes, however, the mechanism for coupling the plug with the body of the fittings is not faultless at all, which often leads to a “breakdown” of the plug, a violation of the tightness of the sewer network and emergency situations.

Known site audit pipeline according to the patent RU for utility model No. 59908 (E03 C / 00, patent: LLC Gazsnabinvest, publ.: 06/27/2009), cover revision of the sewer pipeline according to patent RU for utility model No. 84030 (E02D 29 / 14, patent area: Zhadan M.V., published on 06.27.2009) and revision of the sewer pipeline according to RU patent for utility model No. 106633 (E03F 5/00, patented area: Zhadan M.V., publ.: 07.20.11 )

However, all these devices contain an excessive number of structural parts, assemblies, elements and parts in an individual design, which significantly complicates the operations for their manufacture and assembly into a single system, the operational adaptability of which to the sewer network of modern buildings is also insufficient.

The known site audit of the sewer pipeline according to RU patent for the invention No. 2180381 (E03C 1/122, patented: Ustyugov VA publ.: 10.03.2002), containing the shaped part of the polymer pipe with a bell, elastic seal, ring protrusions and recesses and threaded pipe onto which the plug is screwed.

However, such a device is also notable for its complexity and laboriousness both in manufacturing and assembly, as well as in operation, and it is not sufficiently reliable with respect to its maintainability and operability.

Closest to the claimed technical solution is the shaped part of the sewer pipeline according to RU patent for invention No. 2180382 (E03F 3/04, E03C 1/122, patented area: Ustyugov V.A., publ.: 03/10/2002), which is used a shaped part of a polymer pipe with a bell having external protrusions and internal recesses, an elastic seal and a plug.

However, such a device is also characterized by complexity and complexity both in manufacturing and assembly, and in operation, as well as inadequate performance and reliability.

The technical task of the invention is to increase the availability, maintainability, reliability and reliability of sewer systems, which include polymer cleaners and revisions.

The solution to this problem is achieved by the fact that in the proposed fixative plugs are plugs for sewer cleanings and revisions, which are used as a shaped part of a polymer pipe with a socket having external protrusions and internal recesses, an elastic seal and a plug, the latter is attached to the socket using one U-shaped cut - or a two-link clutch equipped with continuous and (or) sectional flanges, both parts of a single-link clutch and both links of a two-link clutch are connected using spring latches or kerchiefs with screw mount.

In modern civil and industrial construction, polymer pipes and their fittings are predominantly distributed, including using polypropylene (PP), polyethylene (PE) and polyvinyl chloride (PVC). In internal and courtyard sewage systems, to eliminate blockages and plugs in straight horizontal and vertical sections, as well as near pipe turns, pipe fittings with sockets are used, which are cleanings or revisions with an elastic seal and a cap with a cover (see the first analogue of the claimed retainer) . As such a shaped part, a pipe, branch, straight or oblique tee is used, and the cleaning serves to eliminate clogging in one direction, and revision - in two, along and against the direction of movement of wastewater.

The design of the invention is described by drawings, in which Fig. 1 shows the sequence of manufacture and assembly of all elements of cleaning (revision), consisting of a body of the shaped part of the pipe with a bell, an elastic seal, an external protrusion and an internal recess, plugs with a cover and a latch; figure 2 is an enlarged fragment of the cleaning revision, including also all its constituent elements; figure 3 - four types of the claimed retainer, including: - single link with connecting parts of the headscarves with bolts, - two link with the connection of its parts with headscarves with two bolt fasteners, - single link with the connection of parts with a spring latch and - two link lock with its connection links by two spring latches. As can be seen from figure 1, the bell-shaped protrusion of the polymer body (1) of the cleaning (revision) made of a pipe branch, branch, straight or oblique tee, includes a conical part (2) and a cylindrical part (3), in which the housing of the removable clamping plug is placed (4) having an outer flat cover (9) of a round shape. In this case, the outlet of the socket to the outside is equipped with an external rectangular protrusion (5), forming an internal rectangular recess (6), into which an elastic seal (10) is pressed, which is an annular cuff made of dense rubber. The cylindrical retainer housing (7) placed on the protrusion (5) is made with a U-shaped cut in the section and provided with end flanges (8), which are given a continuous smooth and (or) sectional shape. Fragments “a”, “b”, “c”, “d”, “d” and “e” of Fig. 1 describe the assembly process of the cleaning (revision), consisting of: position “a”, which is the original when the cleaning (revision) ) does not yet have additional elements; position "b", which presents the seal prepared for assembly (10); position “c”, which shows the plug (4) prepared for assembly with the lid (9); position “g”, in which the seal (10) and the plug (4) with the cover (9) are already inserted into the body (1) of the cleaning (or revision); position "e", which presents the latch (7) and position "e", which is the national team, where the complete set of cleaning (revision) is fully completed, i.e. in its housing (1) are placed and the seal (10) and the plug (4) and the latch (7).

Figure 2 shows an enlarged fragment (A), including all the elements of the cleaning (revision) shown in Fig. 1e, namely the cylindrical part (3) of the socket of the body (1) of the cleaning (revision), protrusion (5), recess (6) ), a seal (10), a plug (4) with a cover (9) and a latch (7)) with collars (8) and a spring latch (13).

Fragments “a”, “b”, “c”, “d” of Fig. H show transverse sections of the retainer (7), the casing of which is: single-link “a”, and its parts are connected with scarves (11) using a bolt fastener (12 ); two-link “b”, where its links are also connected with scarves (11) using two bolt fasteners (12); single-link “c”, where its parts are connected by means of a spring latch (13) and two-link “g”, where its links are connected by two spring latches (13).

The claimed device operates as follows. Polymer cleanings and revisions, which are mass-produced at pipeline plants and installed in internal and courtyard sewage systems of buildings, work for the first time under normal operating conditions without fail. However, in the event of unexpected extreme situations caused, for example, by blockages and plugs, this equipment does not withstand critical pressure drops, hydraulic and pneumatic shocks, vibrations and leaks, which leads to a “breakdown” of the plugs, i.e. their spontaneous pulling out of cleaning or revision, depressurization of sewer networks and the occurrence of accidents.

The practical use of the proposed clamps, carried out by the author in seven sewer systems of 5 and 9-story residential buildings in Omsk, showed that the described drawback of commercially available polymer cleaners and revisions is completely eliminated, as a result of which these systems begin to work clearly, reliably stable and reliable.
