<p>The invention related to drain, interceptor and practical parts concerns the installation and connection for the draining of waste waters. The mounting is carried out by simple pressure of joints (5) housed in grooves (4) of neck (3) which slides on the male pipe (1) of the drain. The securing is done either manually by means of the knurled screw or with a screw driver. All drawings show that the characteristics of each drain element are identical. Those of drawings (1; 2 et 3) represent the most common parts: drains, interceptors and pratical parts. The drain pipe (1) has a diameter slightly smaller than that of neck (3) of interceptor (2). Its length is variable. The interceptor neck is reinforced due to the presence of semi-circle grooves which receive O-rings (5). The latter will provide for the perfect tightness of the assembly. The passage or ''play''(6), of interceptors or siphons, as a diameter sufficient to allow the pipe (1) to be housed therein. The screw (8) is provided with a knurl which will facilitate the installation or disassembly by hand. Said knurl may also be provided with a slit at its middle point to provide for the utilization of a screw driver. The holes (9) have a diameter corresponding to screws tapped to mechanical pitch. The diameter of tube (7) corresponds to the standards in force. Its length varies with the model. The sleeve (10) (figure 1), as well as the connection parts (figures 2 and 3) have the same references as those of interceptor (2).</p> |
