Description
Technical field
The utility model relates to a kind of waste pipe, refers to a kind of water-drainage tube part that can flexibly connect and have the leakproof water function between the two sections waste pipe especially.
Background technique
Present stage, employed waste pipe is to be connected in series in twos by the multistage water-drainage tube part mostly in the building constructions engineering field, and the termination is by gluing fixing seal, thereby forms the complete waste pipe that runs through floor gap.This waste pipe is because being rigidity serial connection between its each pipeline section, its subject matter is: in the construction stage, waste pipe according to design size by pre-buried and wear and be fixed in the cement board; Along with the growth of building car limit, cement board can occur sinking, and makes rigidly connected waste pipe pressurized fracture easily, causes the generation of leaking.
And Chinese patent ZL201120046913.9 discloses a kind of single standpipe water-drainage tube part tubing with flexible connecting structure, as shown in Figure 1, wherein water-drainage tube part 9 is provided with upper shed 93 and under shed 98, is provided with rubber ring 94 in the upper shed 93, also is provided with several swirl vanes 91 in the pipe fitting 9.Rubber ring 94 is made of the madial wall of an outer side wall with the inside contraction that is connected with outer side wall as shown in Figure 1, and wherein outer side wall is against the inwall of water-drainage tube part 9, and madial wall is in order to seal interference fit with another water pipe 92.When water-drainage tube part is subjected to the axial force extruding, can produces axial float passively by flexibly connecting of rubber ring 94 places, thereby offset axial force, the unlikely pressurized fracture of protection water-drainage tube part.
Yet, the disclosed water-drainage tube part 9 of above-mentioned patent is with after another water pipe 92 engages, the madial wall major part of rubber ring 94 is exposed in the air, make that this part ageing of rubber speed is very fast, be full of cracks very easily occurs and cause seal failure, the accident that causes waste pipe to leak takes place, and influences resident's normal life.
In addition, water-drainage tube part of the prior art inside also is provided with several circumferentially spaced swirl vanes each other, swirl vane 91 as shown in Figure 1, its effect is can make current form eddy flow subsides inner tube wall to rotate descending, keep air-flow unobstructed in the middle part of making in the pipeline, effectively anti-water stopping plug, and reduce draining noise.Yet mainly there is following problem in existing swirl vane:
The swirl vane of some water-drainage tube part inside is along circumferentially arranging to lax, space between per two swirl vanes is bigger, when liquid stream was flowed through swirl vane from top to bottom, the liquid stream in the above-mentioned space of flowing through just flowed out this pipe fitting downwards without eddy flow, caused the eddy flow poor effect of this water-drainage tube part;
On the contrary, in order to guarantee preferable eddy flow effect, another kind of water-drainage tube part is also arranged at a certain pipeline section internal circumferential a plurality of swirl vanes of closely arranging, by being obliquely installed blade, make each blade end-to-end vertically, eliminated axial air gap, but this water-drainage tube part can contract eddy flow section internal diameter because swirl vane arranges overstocked again suddenly, very easily cause water pipe to block in this position, also be unfavorable for implementing to use.
The model utility content
In view of the defective described in the background technique, the purpose of this utility model, namely provide a kind of anti-water-drainage tube part that leaks that flexibly connects, the interference fit of this water-drainage tube part by rubber ring and another water pipe section provides and flexibly connects, and the rubber ring overwhelming majority can not be exposed in the air, guaranteed its working life, the seal durability of the utility model water-drainage tube part can greatly be promoted, had and prevent the effect of leaking.
Above-mentioned the purpose of this utility model is to be realized by following technological scheme:
The utility model provides a kind of anti-water-drainage tube part that leaks that flexibly connects, upper connection, straight length and lower cone section with order grafting vertically, described upper connection has the convergence part of the described straight length of insertion and the convex extension part of described straight length protruding upward, the top of convex extension part has external thread part, the end face of external thread part has a ring-shaped platform, and one is flat on ring-shaped platform top in order to the rubber ring that is connected with another pipe fitting interference fit accordingly with described ring-shaped platform size; Described water-drainage tube part also is provided with a hollow and annular gland above described upper connection and rubber ring, gland has the shoulder that compresses that can compress described rubber ring downwards of annular, compress shoulder and be extended with the internal thread part that the external thread part with described upper connection is screwed downwards, described gland can via with screwing togather of upper connection to the axle center extruding rubber ring of pipe fitting; Wherein, compress the end face that shoulder blocks described rubber ring fully.
Aforesaid water-drainage tube part, the madial wall of described rubber ring from top to down vertically shrinks to the center, makes the diameter of madial wall root edge of rubber ring less than the diameter of the madial wall apical margin of described upper connection; And the internal diameter of the inwall that compresses shoulder of described gland equals the diameter of the madial wall apical margin of rubber ring.By the inwall inclined design of rubber ring, make the easier insertion rubber ring of above-mentioned another pipe fitting mesopore; And the size that compresses shoulder and rubber ring of gland should be able to provide more stable compressing to cooperate mutually and make the stressed even dispersion of rubber ring upper surface, is more conducive to improve its working life.
Aforesaid water-drainage tube part, have between the convex extension part of described upper connection and the convergence part one in the tube chamber the protruding internal shoulder in order to the termination that leans described another pipe fitting of ring; The inwall of described convex extension part and external thread part is isometrical up and down, and described external thread part protrudes along the outer wall radially outward of upper connection convex extension part, makes the thickness of the wall thickness of external thread part and described ring-shaped platform greater than the wall thickness of upper connection convex extension part.Design can make the thicker rubber ring of radial dimension be applied to the utility model whereby, to provide rubber ring more stable interference fit.
Aforesaid water-drainage tube part, the inboard of described upper connection convergence part and the inboard of described lower cone section are respectively equipped with a plurality of circumferentially spaced swirl vanes each other, and the relative water-drainage tube part axioversion of each swirl vane is arranged.Swirl vane is set makes the rotation of current formation eddy flow subsides inner tube wall descending, make the interior middle part maintenance of pipeline air-flow unobstructed, effectively prevent water stopping plug, and reduce draining noise.
