Abstract
The utility model discloses a steel pipe spigot and socket pipe joint with directly-formed pipe ends. The steel pipe spigot and socket pipe joint is characterized in that a socket and a spigot and spigot joint are directly formed at the ends of a steel pipe, one or a plurality of annular grooves are formed on the socket or the spigot of the spigot and socket pipe joint, and rubber seal rings are arranged in the annular grooves. When the joint is used for connecting pipes, the seal rings in the grooves only slide relative to the socket or the spigot and are compressed. The outermost end of the socket expands outwards and is shaped like a horn mouth, and the spigot can be inserted into the socket conveniently. The steel pipe spigot and socket pipe joint with the directly-formed pipe ends has low manufacturing cost, is convenient for field construction and is not only applicable to embedding water delivery steel pipelines but is also applicable to water supply pipelines for factories and mines; in addition, the joint with multiple seal rings is also suitable for low-pressure oil gas pipes.
Description
Technical field
The utility model is about steel pipe and connection thereof, particularly about the steel pipe and the connection thereof of water delivery.Key in technical field herein and describe paragraph.
Background technique
The at present various steel pipes of burying underground of China generally adopt the method for field joint welding to connect.There are many deficiencys in this field welding method, and the common tube welding is to carry out in groove, and the weld seam of steel pipe bottom is because operative position is limit, and the welding operation difficulty is big, and is many when taking a lot of work, and welding quality is also usually influenced; Water conveyance steel tube particularly, tube wall is thinner relatively greatly because of bore, the centering of adjacent two pipes, aim at just more difficult, the field welding quality usually becomes the hidden danger place of pipeline as a result, take place as uneven settlement, these field weldings just can ftracture, and stop labour completely because of the field welding cracking after domestic existing many heavy caliber water conveyance steel tube lines are gone into operation.
The multiple in recent years steel pipe connecting means that not be used in field welding proposes, and patent 98223747.2 large diameter steel pipes and its spigot and socket type pipe joint are exactly a kind of; This patent needs the prefabricated pipe joint, in factory pipe joint is welded on steel tube end part again; Pipe joint is also wanted prior cutting, and it is bigger to implement difficulty.
Key in technical field herein and describe paragraph.
Summary of the invention
The utility model is the lifting to patent 98223747.2, do not need the prefabricated pipe joint is welded on tube end, also do not need cutting, it has greater efficiency, the method for consumable material not with roll off, extruding etc., directly forms the spigot and socket type pipe joint at tube end.
The purpose of this utility model realizes like this: adopt roll off, extruding etc. have greater efficiency, the method for consumable material not, at steel tube end part straight forming spigot-and-socket joint, it is characterized in that: the bellmouth of described spigot-and-socket joint and socket are all at the steel tube end part straight forming; One or more rubber seal by compression are set between joint socket.
Described spigot-and-socket joint is characterized in that: on the bellmouth or socket of above-mentioned spigot-and-socket joint, adopt roll off, pressing method or with the method for welded reinforcement, form one or more annular grooves, rubber seal is placed in the annular groove.
Described spigot-and-socket joint is characterized in that: the seal ring of above-mentioned spigot-and-socket joint is when joint connects, and the position is more stable, can not roll, and just makes slide relative with bellmouth or socket.
Described spigot-and-socket joint is characterized in that: the bellmouth outermost end of above-mentioned spigot-and-socket joint is outwards opened, and is horn mouth, and joint socket just has from the centering characteristic, and socket can insert bellmouth easily.
Four. description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Fig. 3 is another structural representation of the present utility model.
Five. specific implementation method
Embodiment's 1. a kind of structures of the present utility model, as shown in Figure 1: it comprises bellmouth 1 and socket 2, and bellmouth and socket all are in steel tube end part straight forming, typing with methods such as roll offs, extruding.One or more annular grooves 4 are arranged on the bellmouth 1, and it also is that rubber seal 3 just is placed in the groove 4 with method moulding such as roll off, extruding for a groove 4.The bellmouth outermost end is outwards opened, and is horn mouth 5, and it is finished when method moulding bellmouths such as roll off, extruding simultaneously.When socket pushed bellmouth, the socket compresses seal also slipped over rubber seal, connected, sealed and just finish.
Embodiment's 2. another kind of structures of the present utility model, as shown in Figure 2: it comprises bellmouth 1 and socket 2. bellmouths and socket all is in steel tube end part straight forming, typing with methods such as roll offs, extruding.One or more annular grooves 4 are arranged on the socket 2, and it also is that rubber seal 3 just is placed in the groove 4 with method moulding such as roll off, extruding for a groove 4.The bellmouth outermost end is outwards opened, and is horn mouth 5, and it is finished when method moulding bellmouths such as roll off, extruding simultaneously.When socket pushed bellmouth, the socket compresses seal also slipped over rubber seal, connected, sealed and just finish.
Embodiment's 3. another kind of structures of the present utility model, as shown in the figure: it comprises bellmouth 1 and socket 2. bellmouths and socket all is in steel tube end part straight forming, typing with methods such as roll offs, extruding.One or more annular grooves 4 are arranged on the bellmouth 1, and the method that reinforcing bar 6 is gone up in the welding of groove 4 usefulness forms, and rubber seal 3 just is placed in the groove 4.The bellmouth outermost end is outwards opened, and is horn mouth 5, and it is finished when method moulding bellmouths such as roll off, extruding simultaneously.When socket pushed bellmouth, the socket compresses seal also slipped over rubber seal, connected, sealed and just finish.
Steel tube end part straight forming spigot-and-socket joint fabricating cost is low, and site operation is convenient, not only is suitable for and buries the water conveyance steel tube line underground, also is suitable for the process water pipeline in factory, mine, the also applicable mesolow oil gas of the joint of a plurality of seal rings pipe.
