The utility model relates to a kind of tubing perforate linkage structure, mainly by tubing and connecting head, formed, the exit orifice of tubing and the through hole of connecting head are communicated with, between described tubing and connecting head, be provided with flexible seal washer, seal washer middle part has perforation to be connected with exit orifice and through hole, the postive stop baffle 5 that seal washer 3 peripheries also have a circle to adapt with it.Therefore, the sealing when tubing perforate that this tubing perforate linkage structure can realize various bores and material is laterally connected, structure is very simple, install and change very easy to be quick and without special device again, be not subject to the restriction of installation environment, cost-saving, component interchangeability is good simultaneously, good airproof performance after connecting, long service life, tolerates any high pressure and still can keep good sealing, is good environment-friendly products, there are wide market prospects, be worthy of popularization very much.
Description
Technical field
The utility model relates to a kind of pipe connecting structure, particularly a kind of structure of tubing perforate connection outlet.
Background technique
In daily life or production process, the tubing of the use such as water delivery, oil transportation, when needs lateral opening divides connection, has and can hold an outlet at tubing middle part, then by the mode of welding or hot melt adhesive, they is interconnected and is sealed.Although these two kinds of modes have solved the lateral opening linkage structure of plastic cement, metal, aluminium-plastic composite pipe or steel-plastic composite pipe etc., but still there is certain deficiency: hot melt adhesive connection is only suitable in plastic pipe, need special device and technician to install, intensity and tolerance level are not high, weld complex procedures, cost is high, perishable, simultaneously they all exist construction duration, environmental requirement high can not be under water, oily inferior operation, the deficiencies such as maintain and replace inconvenience.
Model utility content
The purpose of this utility model is that a kind of tubing perforate linkage structure of easy for installation, quick, efficient, durable and good airproof performance is provided for overcoming above-mentioned shortcoming.
The purpose of this utility model can be achieved as follows: this tubing perforate linkage structure is mainly comprised of tubing and connecting head, the exit orifice of tubing and the through hole of connecting head are communicated with, between described tubing and connecting head, be provided with flexible seal washer, seal washer middle part has perforation to be connected with exit orifice and through hole, the postive stop baffle that seal washer periphery also has a circle to adapt with it.
As further improvement of the utility model: the Thickness Ratio seal washer of the postive stop baffle of this tubing perforate linkage structure is little.
As further improvement of the utility model: the postive stop baffle of this tubing perforate linkage structure can be fixed on connecting head, can be fixed on tubing, can be also movable.
As further improvement of the utility model: the seal washer circumferential profile of this tubing perforate linkage structure can be circular or square.
As further improvement of the utility model: also can form a circle projection shirt rim in the seal washer of this tubing perforate linkage structure week, the periphery of the exit orifice of tubing is just wrapped up in shirt rim.
The utility model by establishing a flexible seal washer between tubing and connecting head, and by postive stop baffle, limit the expansion space of seal washer, on the one hand, make outlet nose end and the seal washer of tubing, between connecting head and postive stop baffle, form pipeline sealing space, seal washer positions by postive stop baffle, on the other hand, while being connected with the liquid of certain pressure in tubing, in this confined space, there is certain hydraulic pressure, under this hydraulic pressure, seal washer will be pushed to postive stop baffle and press thereon along lateral direction, because postive stop baffle is to the effect of seal washer start stop bit, at this moment seal washer is due to the compressing being under pressure, add upper sealing washer and there is elasticity, seal washer can only be out of shape, the outer rim that makes seal washer is pressed tightlier tightlyer to the outer wall of tubing and connecting head inwall and postive stop baffle, thereby tubing has been played to extraordinary connection seal action, and hydraulic pressure is larger in tubing, its sealability is better, even when the fluid pressure being connected with in tubing is zero, because being connected head, seal washer is pressed on tubing outside with certain pressure, leakproofness between them can meet its sealing completely.Therefore, the sealing when tubing perforate that this tubing perforate linkage structure can realize various bores and material is laterally connected, structure is very simple, install and change very easy to be quick and without special device again, be not subject to the restriction of installation environment, cost-saving, component interchangeability is good simultaneously, good airproof performance after connecting, long service life, tolerates any high pressure and still can keep good sealing, is good environment-friendly products, there are wide market prospects, be worthy of popularization very much.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Accompanying drawing is the schematic diagram of the utility model tubing perforate linkage structure.
Embodiment
As shown in drawings, tubing perforate linkage structure described in the utility model, mainly by tubing 1 and connecting head 6, formed, the exit orifice 2 of tubing 1 and the through hole of connecting head 67 are communicated with, between described tubing 1 and connecting head 6, be provided with flexible seal washer 3, seal washer 3 middle parts have perforation 4 to be connected with exit orifice 2 and through hole 7, the postive stop baffle 5 that seal washer 3 peripheries also have a circle to adapt with it.The Thickness Ratio seal washer 3 of described postive stop baffle 5 is little.Described postive stop baffle 5 can be fixed on connecting head 6, can be fixed on tubing 1, and can be also movable.Described seal washer 3 circumferential profile can be circle or square.State and also can form a circle projection shirt rim interior week of seal washer 3, the periphery of the exit orifice 2 of tubing 1 is just wrapped up in shirt rim.
When the utility model is installed and used, seal washer 3 is pressed on exit orifice 2 peripheries of tubing 1, with postive stop baffle 5, seal washer 3 is enclosed again, and then connecting head 6 is pressed on seal washer 3 and postive stop baffle 5, because the Thickness Ratio seal washer 3 of postive stop baffle 5 is little, so being first means of press seals packing rings 3, connecting head 6 presses again postive stop baffle 5, simultaneously, connecting head 6 by lug 8 lock rings on tubing 1, as added a connecting head 6, by lug 8 by two connecting heads 6 docking lock ring on tubing 1, or available rope or steel band are tightened hoop by lug 8 on tubing 1 by connecting head 6., be also noted that Thickness Ratio seal washer 3 when postive stop baffle 5 is large or when consistent here, postive stop baffle 5 needs to adopt the material with certain elasticity and intensity to make and could realize seal action, especially in tubing, presses the sealing while being zero.In addition, connecting head 6 can be connected use with other pipelines by interface 9.When postive stop baffle 5 is fixed on connecting head 6 or on tubing 1 time, seal washer 3 is placed in postive stop baffle 5 upper installation for another example.
In a word; although the utility model has exemplified above-mentioned preferred implementation; but should illustrate; although those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in protection domain of the present utility model.
