Abstract
A rolling enclosure-typed plastic pipe fitting comprises a coupling part of a pipe fitting, a rubber packing ring, a fixing rubber gasket, a pressing sheet and a fixing cap. An internal of the coupling part of the pipe fitting is arranged with a chase of the packing ring, the internal is of cone shape, the rubber packing ring, the fixing rubber gasket and the pressing sheet are sequentially equipped in the coupling portion of the pipe fitting when installing, and the fixing cap is connected with the coupling portion of the pipe fitting via screwed connection. The utility model employs the manner of flexible connection to connect the pipe fitting with a pipe body, and is simple in structure, convenient and prompt in installation and demounting, reliable and fast in connection and good in sealing effect. The utility model is applicable for plastic pipe fittings and valves such as inner-outer silk tees, inner-outer silk bends, inner-outer pair silks and inner-outer silk joints or the like.
Description
The utility model belongs to pipe joint, is specifically related to a kind of rolling seal formula plastic pipe.
At present, national departments concerned is recommended in building material industry and uses free of contamination environment-friendly products one plastic-metal composite pipe, plastic tube, and the pipe fitting supporting with this composite pipe and plastic tube is a lot, can be divided into metal species and plastics class substantially.Metal pipe element fabricating cost height easily gets rusty in the use, and water quality is had pollution; For being rigidly connected, it is not lasting to seal between the pipe fitting, and the time has been grown seepage more; The pipe fitting internal diameter dwindles 50% than composite pipe internal diameter, and water flow is significantly reduced, and the joint very easily stops up foreign material, makes troubles to use.Adopt binder bonding when plastic pipe is connected with plastic tube with composite pipe, can not construct continuously during operation, leak glue, produce seepage, pipe fitting must be sliced off together with body, use new pipe fitting bonding again, cause waste if any the part.
The purpose of this utility model provides a kind of simple in structure, easy to operate, adopts the rolling seal formula plastic pipe that flexibly connects.
Technical solution of the present utility model is: rolling seal formula plastic pipe is made up of pipe fitting attachment portion, rubber seal, fastening cushion rubber, clamping piece, fastening cap, the pipe fitting attachment portion is provided with outside thread, be provided with o-ring groove with the interior circle of body external diameter coupling, interior round opening is tapered; Fastening cap is provided with internal thread, the internal diameter of fastening cap through hole, rubber seal, fastening cushion rubber, clamping piece all is complementary with the body external diameter, rubber seal, fastening cushion rubber, the clamping piece pipe fitting attachment portion of packing into successively, fastening cap is threaded with the pipe fitting attachment portion.
Further describe the utility model below in conjunction with accompanying drawing:
Fig. 1 is a rolling seal formula plastic pipe structural representation;
Fig. 2 is for forming the modular construction schematic representation of plastic pipe.
Wherein: 1, pipe fitting attachment portion 2, rubber seal 3, fastening cap 4, clamping piece 5, fastening cushion rubber 6, body 7, groove
Fig. 1 is the equal tee plastic pipe, the parts of forming plastic pipe as shown in Figure 2, pipe fitting attachment portion 1 is provided with outside thread, fastening cap 3 is provided with internal thread.During installation, rubber seal 2, fastening cushion rubber 5, clamping piece 4, fastening cap 3 are sleeved on successively on the body 6 of well cutting, rubber seal 2 is positioned at body 6 ends, body 6 is aimed at the pipe fitting inlet to be advanced, rubber seal 2 produces friction rolling under the relative movement of body and pipe fitting, seal ring snaps in the groove 7 of circle in the pipe fitting attachment portion automatically, then fastening cushion rubber 5, clamping pad 4 is pushed the taper mouth place of pipe fitting attachment portion 1, screws fastening cap 3 and gets final product.
According to design of the present utility model, present employed plastic pipe all can adopt this structure, and as the threeway of inside and outside silk, inside and outside silk elbow, inside and outside it is simple in structure to silk, interior nipple, valve etc., fabricating cost is low.Can also adopt this flexible connection mode for existing metal pipe element, with thorough solution pipe fitting leakage problems.
Adopt that this structure can cancel that oil is appointed, union, to links such as silks, fitting to fitting be connected with body get final product, do not need auxiliary material such as raw meal belt, lead oil, flax silk in the construction, install, convenient disassembly is quick, connection is reliably firm, good sealing effect.
The utility model adopts flexible connection mode, can eliminate the defective that the tube outer diameter foozle is brought, and can reach the effect of good seal after the installation equally.This structure is suitable for the threeway of inside and outside silk, inside and outside silk elbow, inside and outside to silk, the first-class plastic pipe of inside and outside wire connection and valve employing.
