Description
The invention belongs to and use the drainage facility field, relate to the linkage and the method for production thereof of a kind of feed pipe and water device water inlet pipe.
So-called water device mainly is meant: water storage utensil and water appliance, as: the water tap that places such as industrial, civilian water storing tank, washroom, kitchen are used, ice machine, washing machine, geyser etc., itself all have water inlet pipe (mouth), control valve and outlet pipe (mouth), water is delivered to the water device through feed pipe, and feed pipe is connected by pipe fitting with water device water inlet pipe (mouth).
In the prior art, the connected mode of feed pipe and water device water inlet pipe (mouth) has two classes substantially, one class is to interconnect with hard tube and pipe fitting, and need site preparation to install mostly, another kind of is that the flexible pipe that utilizes the end of the system of giving to have connector interconnects, market direct marketing, this flexible pipe mostly are greatly has the plastic flexible pipe of strengthening silk screen; The former is weak point: manufacture install tired lock, time-consuming, heavy, cost is high, and length is not easy adjustment; Latter's weak point is: flexible pipe is all longer, needs coiling or crooked back to use, thereby forms the flat fragile position of folding easily, and it is unimpeded not only to influence water delivery, and pressurized explosion easily, sometimes may be short slightly again, and cause fragile the connection easily to meet accident.
The objective of the invention is to: the linkage of a kind of feed pipe and water device water inlet pipe is provided and manufactures method, overcome the foot of prior art, especially be fit to the feed pipe with pressure of different-diameter and interconnecting of water device water inlet pipe (mouth), can directly manufacture installation at the scene, the system of also can giving is installed, convenient and swift, save time, laborsaving, length is adjusted easily, be not prone to the frangible portion position, manufacture easily, cost is low.
Concrete scheme of the present invention is as follows: the linkage of feed pipe and water device water inlet pipe, have metal bellow 1 and corresponding link, it is characterized in that: the two ends of metal bellow 1 have the crowded ripple flange 2 with the moulding of special manual corrugation forcing-out device, each crowded ripple flange 2 inboard, corresponding can being enclosed within on the metal bellow 1 with the special- purpose nut 3 and 4 that feed pipe 7 and water device water inlet pipe 8 are tightly connected mutually arranged respectively, and supporting sealing mat 5 and 6 are respectively arranged.
The method for production of the linkage of feed pipe and water device water inlet pipe is characterized in that: comprise the steps: in regular turn
A) measure to determine the specification that is connected of feed pipe 7 and water device water inlet pipe 8, comprise the specification of connecting thread and the spacing of the two and required metal bellow 1;
B) get special- purpose nut 3 and 4 and basigamy cover sealing mat 5 and 6 ready according to connecting thread;
C) intercept the metal bellow 1 of required specification and length according to the two spacing;
D) with the special manual corrugation forcing-out device ripple flange 2 is squeezed in one end moulding of metal bellow 1;
E) from the other end of metal bellow 1 by direction, put the special- purpose nut 3 and 4 that has supporting sealing mat 5 and 6 respectively according to the order of sequence;
F) with the special manual corrugation forcing-out device ripple flange 2 is squeezed in the other end moulding of metal bellow 1 again;
A kind of special manual corrugation forcing-out device of using in the linkage method for production of feed pipe and water device water inlet pipe, form by main body and clamshell type anchor clamps two parts, main part has cylinder body 21, the one end is equipped with end cap 24, guide rod 22 passes end cap 24, handle 25 is equipped with in its outer end, piston 23 is equipped with in the inner, it is characterized in that: on another end wall of cylinder body 21 axially open 27 is arranged, contact cabin 28 is arranged in the opening 27, on the inwall appropriate location, radial section orientation of this cabin inner cylinder body 21, have with the clamshell type anchor clamps supporting groove 29 is installed, piston 23 can reciprocatingly slide in cylinder body 21 under the drive of guide rod 22, and its front end can enter the contact cabin 28, thereby roof pressure is on the top end face 26 of the metal bellow 1 that is clipped the location by the clamshell type anchor clamps; The clamshell type anchor clamps go to upper and lower clamping plate 30 symmetries clamshell type again, have cylindrical clamping hole 31 on it, and the inwall in this hole is the interior ripple type identical with respective metal corrugated flexible hose 1, two to five circles; The inwall in cylindrical clamping hole 31 also can be the supporting smooth cambered surface of maximum outside diameter of internal diameter and respective metal corrugated flexible hose 1, but its base must be close to a cylindrical boss hole 32, and the inwall in this hole must coincide with the trough position of corresponding metal corrugated flexible hose 1; Upper and lower clamping plate 30 also have the location and coincide and separating mechanism.
