Description

[Detailed Description of the Invention] (Object of the Invention) The present invention relates to a method for joining egg-shaped ceramic tubes.The purpose of the present invention is to have good starch syrup properties, and to easily prevent twisting of the ceramic tubes during installation. It is an object of the present invention to provide a method for joining egg-shaped ceramic tubes that can be modified and effectively prevent twisting of the ceramic tubes after installation.

(Prior art) Compared to circular ceramic tubes, phase-shaped BIJ pipes have the following characteristics: the eccentric velocity does not change much even when the flow rate changes, and the flowing water cross section has a Je-like shape that makes it difficult for organic matter to accumulate even in small equipment. Being there,
It is used for distribution because it has the advantage of being resistant to vertical carts. On the other hand, due to its shape, Ugata FA has its own problems, such as the need to properly match the bottom of the tube and the need to prevent twisting of the tube. are doing.

As shown in FIG. 6, the conventional method for joining oval U+J tubes involves connecting the inner peripheral surface of the socket 11 of the oval ceramic tube and the
Rubber-like joining members 13 and 14 are adhered in advance to the outer circumferential surfaces of the cylindrical tubes 13 and 14 to a nearly uniform thickness, and the vaginal opening 12 of one oval-shaped porcelain tube is connected to the socket 11 of the other ovoid-shaped porcelain tube. A method of joining the oval ceramic tubes by inserting the surface joining members 13 and 14 and deforming and bringing them into close contact with each other, or as shown in FIG. Rubber-like joining member 22 provided
is glued to the inner peripheral surface of the socket 23 of the egg-shaped ceramic tube, and this socket 2
Insert the vaginal opening 24 of another egg-shaped porcelain tube to which no rubber-like joining member is attached into the inside of 3, and deform the tongue piece 21 at the time of insertion to attach it to the outer peripheral surface of the vaginal opening 24 (support). There was a method of joining egg-shaped ceramic tubes by attaching them to each other. However, the former joining method involves gluing rubber-like joining members 13 and 14 to both the inner circumferential surface of the socket 11 and the outer circumferential surface of the vaginal opening 12 of the egg-shaped ceramic tube to a substantially uniform thickness. , W at the time of joining
Since the contact area of the J joint members 13 and 14 is large, the watertightness is good.
There is a drawback that the correction is trivial, and the joining method used by 'UK's deforms the tongue piece 21 to join the egg-shaped porcelain tubes together, so it is difficult to fix the egg-shaped porcelain tubes even if there is a slight twist. Although twisting can be easily corrected by rotating, there are drawbacks such as insufficient water compatibility and the risk of water leakage or flooding.

(Hatsuro's configuration) The present invention was made in view of the above-mentioned problems caused by the conventional method of joining oval-shaped 1iIJ tubes, and its gist is as follows:
1i1j Attach a rubber-like first joining member with a relatively thick tongue protruding from the far end to the circumferential surface of the socket at one end of the tube! A rubber-like connecting member 2 of uniform thickness is adhered to the outer peripheral surface of the vaginal opening at the other end, and
a tube bottom; and the second tube at a position substantially opposite to the tube bottom.
A convex portion for fitting the tube bottoms is integrally provided in the inner part of the joining member, and examples will be described below with reference to Appendix 18I.

In Figures 1 and 2, after applying a primer containing silicone resin as a main component to the inner peripheral surface of the socket 1 provided at one end of the egg-shaped ceramic gA, The sponge rubber ring 2 is inserted and brought into contact with the stepped portion 1a of the socket 1, and then a slit 3a for forming a tongue piece 4a, which will be described later, is provided at the tip. For forming joint members with similar shapes! 3 is inserted into the receiver O1 and brought into light contact with the end surface of the sponge ring 2. At this time, a release agent is applied to the outer peripheral surface of the joining member forming mold 3, and the width of the gap formed between the joining member forming mold 3 and the inner peripheral surface of the socket 1 is The bonding member forming mold 3 is inserted into the socket l so that the bonding member is formed uniformly over the entire length.

Next, the outer peripheral surface of the joining member mold 3 and the socket are filled with a two-component room-temperature curing plastic liquid containing polymer as the main ingredient, and left in this state for a required period of time to allow the plastic liquid to harden. fJ for joining IU molding! 3 and the sponge rubber ring 2 are removed, as shown in No. 4181I, there is a relatively thick tongue piece 4 at the rear end.
A rubber-like first joint portion U4 with a protruding portion a is adhered to the inner circumferential surface of the socket l of the egg-shaped ceramic tube A. Here, the primer applied to the inner circumferential surface of the socket L penetrates into the surface layer of the inner circumferential surface of the socket L, and the silicone resin, which is the main component of the primer, and the two-component cold-curing plastic liquid The urethane prepolymer, which is the main ingredient, reacts and the rubber-like first joining member 4 becomes the socket! Strongly W on the inner circumferential surface of! It will be worn. As shown in FIG. 3, the first joining member 4 is attached to the outer peripheral surface of the vaginal opening 5 at the other end of the egg-shaped ceramic tube A with a uniform thickness.
At the same time, a rubber-like second joint member 6 of the same configuration is bonded, and the second joint member 6 is bonded to the bottom A of the egg-shaped ceramic tube A and the inner part of the second joint member 6 at tliA, which is almost opposite to this tube 165A1. Convex portions 6a and 6b for aligning the bottom of the bent tube are integrally provided at the portion.

To join the egg-shaped ceramic tubes A together, as shown in Figure 4, lift the egg-shaped ceramic tube A and place its stone grain 5 opposite the socket 1 of the existing egg-shaped ceramic tube A. Then, while aligning both #β-shaped ceramic tubes A so that their bottoms match, insert the stone grain 5 of one of the egg-shaped ceramic tubes A into the socket l of the existing egg-shaped ceramic tube A. As shown in FIG.
The second joint member 6 adheres to the outer circumferential surface of the second joint member 6.
, containers s6m and 6b integrally provided in the hag-odor half of the second joint member 6 at position A, respectively, are located at the bottom of the tube of the first joint member 4 and approximately at the portion opposite to the bottom of the tube. Closely attached to the front half. The tube bottoms of the oval mts are now joined to each other with their tube bottoms aligned.

(Effects of the Invention) The present invention deforms a relatively thick tongue piece attached to the first joining member by adhesively bonding it to the inner circumferential surface of the socket of the oval-shaped LI# tube. Since the egg-shaped ceramic tubes are joined by being in close contact with the second joining member adhered to the outer peripheral surface of the stone grain of the other egg-shaped ceramic pipe, the (support) area of each joining member becomes large and water In addition to improving drainage properties, the tongue piece is not glued to the inner circumferential surface of the socket even after joining, so installation may sometimes occur 1iiiI7
The twist of W can be easily corrected and returned to the normal position.

In addition, the tube bottom in the oval-shaped 1-tube difference [ ] and each convex part for i-time alignment provided on the part opposite to this are connected to the first joining member adhered to the inner circumferential surface of the socket. Since it is closely attached to the front half of the hand, if for some reason the egg-shaped pottery tube is subjected to vibrations or vibrations, each of the convex portions will cause the bottom of the egg-shaped pottery tube to shift, or the egg shape will occur. In order to effectively prevent twisting of the porcelain pipes, the installation is performed so that the bottom of the egg-shaped porcelain tubes will hardly shift or the ovoid porcelain pipes will become twisted, and will remain in good condition for a long time. It is possible to perform drainage etc. at 60.
