Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments, based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Please referring to Fig. 1-4, the present invention provides a kind of technical solution, and a kind of high closeness PVC bellows connects equipment, including
For connecting the conduit 3 of the first bellows 4 and the second bellows 5, the both ends of conduit 3 are respectively fixedly connected with 1 He of first connecting portion
Second connecting portion 2, and first connecting portion 1 is identical with 2 structure of second connecting portion, first connecting portion 1 is connected with the first bellows 4
It connects, second connecting portion 2 is connected with the second bellows 5；The first connecting portion 1 includes column casing 9, and column casing 9 is plugged on first
The inside of bellows 4 has been fixedly and coaxially connected retaining ring 6 on one end lateral wall that column casing 9 is connect with conduit 3, has been fixed on retaining ring 6
To the hold-down mechanism that the first bellows 4 compresses, the expanding structure 14 for increasing leakproofness is provided on the side wall of column casing 9.
In the present embodiment, column casing 9 is the cylindrical tube shape structure of both ends open, and the one of the open at one end and conduit 3 of column casing 9
End port is connected, and port lateral wall of the column casing 9 far from conduit 3 is cone structure 10, and expanding structure 14 is located at cone structure
10 middle part.
In the present embodiment, expanding structure 14 includes the annular groove 16 for being provided with 10 middle part of cone structure, and the slot bottom of annular groove 16 is logical
It crosses multiple through-holes 17 to be connected to the inside of column casing 9, the opening of annular groove 16 is fixedly connected with rubber pad 15.
In the present embodiment, hold-down mechanism includes the swivel nut 8 being coaxially fixed on retaining ring 6, and 8 housing of swivel nut is in column casing 9
On, and there are gap between swivel nut 8 and column casing 9, pressing sleeve 7 is threaded on swivel nut 8.
In the present embodiment, pressing sleeve 7 is fixedly and coaxially connected and is formed by direct tube section 11 and conical cylinder section 12, is led directly to section 11 and is threadedly coupled
On swivel nut 8, and handle 13 is fixed on the lateral wall of direct tube section 11, handle 13 facilitates rotation pressing sleeve 7, the taper of conical cylinder section 12
It is identical as the taper of cone structure 10.
The principle of the present invention and advantage: this kind of novel anti-leakage closes water ripples tube connector, is being attached behaviour to bellows
When making, process is as follows:
By taking the first bellows 4 and the connection procedure of first connecting portion 1 as an example:
Step 1: the direct tube section 11 of pressing sleeve 7 is screwed off from swivel nut 8, and the port side of 7 conical cylinder section 12 of pressing sleeve is set on first
On bellows 4, the port side heating of the first bellows 4 is then made into its softening using electric heater, so that column casing 9 is inserted into
The first bellows 4 is inserted into after the softening of the first bellows 4 in one end of the cone structure 10 of column casing 9 by the inside of the first bellows 4
Inside, and make the gap location being inserted between swivel nut 8 and column casing 9 at the port of the first bellows 4, cone structure 10 plays
Guiding role reduces the difficulty that column casing 9 is inserted into the first bellows 4, and column casing 9 is after being inserted into 4 inside of the first bellows, with temperature
4 cooling meat of the first bellows of reduction of degree is simultaneously fixedly connected on column casing 9, improves connective stability, and easy to operate
It is convenient；
Step 2: the direct tube section 11 of pressing sleeve 7 is threaded on swivel nut 8 using handle 13, as direct tube section 11 is along swivel nut 8
It is axial close to retaining ring 6 under the action of screw-driven, while it is close to cone structure 10 to drive conical cylinder section 12, to pass through cone
Cylinder section 12 and the mutual extrusion of cone structure 10 are stably connected with the first bellows 4 with column casing 9, and conical cylinder section 12 is to first
The pressure that bellows 4 applies also increases the stickiness of the first bellows 4 and cone structure 10 on column casing 9, to help to mention
For high closeness；
Step 3: the second bellows 5 is connect with second connecting portion 2 according to step 1 and step 2, first wave after the completion of connection
When 4 delivered inside gas of line pipe or liquid, gas or liquid are flowed into annular groove 16 by through-hole 17, and are applied to rubber pad 15
Outside pressure, to further increase closure, is kept away so that rubber pad 15 swells and is adjacent to the inner wall of the first bellows 4
Exempt from junction leak or gas leakage, since annular groove 16 inside through-hole 17 and the first bellows 4 by being connected, inside annular groove 7
Pressure it is identical as 4 internal pressure of the first bellows, when 4 internal pressure of the first bellows increase when annular groove 7 in pressure also increase
Greatly, and to the pressure of rubber pad 15 also increase, so that the tightening degree of rubber pad 15 and the first bellows 4 is reinforced, and sealing effect
Fruit is more preferable, to avoid junction leak or gas leakage when bellows interior conveying high-pressure.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art within the technical scope of the present disclosure, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be subject to the protection scope in claims.
