Description
(1) technical field:
The utility model relates to a kind of draining pipe joint, and flexible interface is cylinder iron managed in particularly a kind of draining.
(2) background technique:
At present, employed drainage pipe interface on the Domestic market, mainly contain following several: 1, the flexible interface cast iron tube of joint socket formula flange plate connection: fall behind though this product has avoided old-fashioned cast iron tube to install, during Cost of repair and maintenance, can't guarantee non-leakage and do not have a defective of shock resistance, but the annexes such as flange plate that increase newly are too many, no matter are from fabrication and processing or from installing, all increase certain degree of difficulty, also improved the cost of product simultaneously; 2, no bellmouth collar-shaped flexible interface cast iron tube: though this product has accomplished that installation and maintenance conveniently, and the good characteristics of anti-seismic performance have been reached, but because its no bellmouth, full tube hoop and rubber sleeve connect, the perpendicularity except that can't guarantee to install the time, and different because of the employed material temperature variation of pipe collar, pipe collar is easy to occur loosening phenomenon, be difficult to guarantee non-leakage when therefore, the normal phase uses; 3, PVC plastic drain-pipe: this product has been accomplished easy for installation, reasonable price, but in use there are many defectives, this product aging quality resistance of domestic production at present is not enough in addition, crack performance has in use appearred in portioned product, more seriously, the noise that this product is produced in drainage procedure is very serious, and the owner does not have good evaluation to it.
(3) summary of the invention:
The purpose of this utility model is to design a kind of draining and cylinder iron manages flexible interface, it be a kind of have meet NBS, installation and maintenance convenience, no annex, cheap and can guarantee non-leakage new design scheme.
The technical solution of the utility model: flexible interface is cylinder iron managed in a kind of draining, comprises the cast iron tube two ends, it is characterized in that the end in the cast iron tube two ends is a bellmouth, and there is a platform bottom in the bellmouth; The other end is a socket, and there is a platform the outer bottom of socket; One end of said socket is inserted in the end of bellmouth, the head end of bellmouth and socket is butted on respectively on separately the platform, there is O-ring seal at head end separately and contact with platform place separately, bellmouth has corresponding screw with the tube wall place of socket, and corresponding screw is aimed at the back according to being threaded fixing bolt.
Have on the platform separately that the head end of above-mentioned said bellmouth and socket is butted on respectively and place the limited impression of O-ring seal separately, on the corresponding O-ring seal of placing the positive stop lug boss of O-ring seal is separately arranged, place the limited impression of O-ring seal separately on the platform separately of said bellmouth and the head end of socket and be drive fit with the positive stop lug boss of O-ring seal separately and be connected.
The corresponding screw at above-mentioned said bellmouth and socket tube wall place with can have 3-6 according to the fixing bolt that is threaded.
Using method of the present utility model is: when doing pipe joint, the bellmouth and the corresponding O-ring seal of socket are placed on being connected separately on the platform of bellmouth and socket respectively, again socket is inserted in bellmouth and finds each self-corresponding screw accurately, at last with fixing bolt according to being threaded in each self-corresponding screw.
Superiority of the present utility model is: 1, this programme has been avoided the defective of present domestic used waste pipe Placement fully, and production technology is simple, and except that connecting Luo bolt and anti-seepage sealant circle, no any other annex greatly reduces cost of production; 2, avoid direct contact between the tube and tube, can really play the effect of flexible interface, accomplished that simultaneously installation, maintenance is convenient, shortened the installation time, prolonged working life; 3, anti-seismic performance is good, meets the requirement of country to this series products anti-seismic performance, owing to increased the length of joint socket, and passed through machining at the joint socket place, therefore, the perpendicularity when having guaranteed to install; 4, be provided with the two seals cushion rubber and the antiseepage groove of bellmouth and spigot, avoided the generation of seepage phenomenon fully; 5, this programme is according to the standard design of GB/T12772-1999, therefore, meets NBS fully, and employed connection Luo bolt also adopts standard piece, need not special processing; 6, this product both had been fit to individual workship's production, also was fit to the large-scale production in batch of massive casting factory, and the good commercial DEVELOPMENT PROSPECT is arranged, and was the optimal design that meets the national conditions will of the people.
