CN2162577Y - Pipe joint assemblage with quick dismounting - Google Patents

Abstract

The utility model relates to a connecting component of a quick disassembling component. A body 1 and a nut 4 are connected in a detachable mode and can move correspondingly in the axial direction, which causes a sealing ring 2 to be deformed by a pressure ring 3 to block clearance, keep sealing and prevent the air and the water from leaking. The utility model has the advantages of no need of tools for assembling and disassembling, rapidity, simplicity, no pollution and low cost and can be used in coal gas, compression air, tap water, discharged waste water, chemical industry liquid, electric light wires, power cables, communication pipes, etc.

Description

Pipe joint assemblage with quick dismounting

The utility model relates to cylindrical body and connects, especially the quick releasable connection assembly of garden cylindricality hollow pipe.

Existing industry and civil pipeline, the particularly connection of middle small-bore pipeline, many with irony joint links, with fabric, plastics, nonmetal flexible material as sealing material, thereby pipe arrangement technology trouble, must select special skilled worker for use, and oxidation, contaminated-fluid diminish health, and price is higher in addition, the danger of severe cold bursting by freezing is arranged again, thereby the requirements at the higher level of incompatibility modern society.

At above-mentioned deficiency, the utility model proposes a kind of new solution of quick removable pipe fitting connection part.Its is with hydraulics end force sealing principle, and the medical bottle cap cushion is made up with being threaded, and constitutes a kind of low pressure pipe fitting linkage unit.

The utility model is with being threaded, need not any instrument, and everybody can install voluntarily, thereby dismounting is convenient especially.Seal ring is subjected to compression swelling, blocks the escape of liquid slit, thereby can not become flat and leak, and is safe and reliable.All component is the solid non-toxic material can not cause fluid contamination and oxidation, thereby sanitation and hygiene, and working life is also long especially.As long as material is selected suitably, winter can bursting by freezing, and working life can be for 50 years.

The utility model is applicable to departments such as coal gas, pressurized air, tap water, sewer, chemical liquid, lighting circuit, power cable, communication pipeline.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is body 1 sectional view.

Fig. 2 is seal ring 2 partial sectional views.

Fig. 3 is pressure ring 3 positive views (a) and side view (b).

Fig. 4 is nut 4 partial sectional views.

Fig. 5, Fig. 6, Fig. 7 are ssembly drawing.

Body 1 each port has outside thread, endoporus " chamfering " curve have various ways (a, b, c, d), and any surface finish.Body 1 is made of hard material, as plastics, metal etc.

Seal ring 2 tangent planes are like indent f(evagination e) curvilinear triangle, end face can have indent curve bath 9.Seal ring 2 also can adopt the O RunddichtringO.Seal ring 2 is made of soft, closely knit, highly resilient material, as rubber, soft plastic, refined lead etc.

Pressure ring 3 tangent planes are like recessed (protruding) curvilinear triangle, and end face can have convex tendon h and seal ring 2 indent curve bath g to match, and has at least one and half breach, its center line to can be straight line i, broken line k or camber line j on the ring body.Breach is linked to be a whole circle at small end l place.Sometimes, pressure ring 3 can replace (Fig. 7) by plain washer.Pressure ring 3 is by withstand voltage, flexible material, as formations such as plastics, ebonite.

Nut 4 indents (evagination) curved surface and pressure ring 3 evaginations (indent) curved surface match, and (sometimes, available straight hole replaces concave-convex curved surface (Fig. 7)), internal thread and body 1 outside thread match.Nut 4 is made of hard material.

Body 1, seal ring 2, pressure ring 3 and nut 4, latus rectum unanimity in it.Indent, outer convex surface cooperate consistent.

Body 1 matches with nut 4 screw threads.Treat hand-screw jack panel 4, make seal ring 2 be subjected to the axial force of pressure ring 3, thereby, blocked the fluid internal leakage, thereby can not become flat under the low pressure, leak to the expansion of inner and outer diameter direction.
