Abstract
The utility model discloses a polypropylene pipe fitting in threaded connection, which relates to the field of pipeline connection devices, and solves the problems of high cost, inconvenience and the like when existing polypropylene pipes are connected. Two ends of the polypropylene pipe fitting in threaded connection are respectively provided with an internal thread or an external thread. The polypropylene pipe fitting in threaded connection is simple in structure, low in cost and convenient in operation.
Description
Technical field
The utility model relates to a kind of pipeline connecting pipe fitting device, particularly relates to a kind of polypropylene pipe fitting that is threaded.
Background technique
At present; The polypropylene pipe fitting that polypropylene pipe fitting manufacturing enterprise produces roughly has three types: thermofusible spigot connection pipe fitting, embedded with metal inipple connection pipe fitting and electric smelting connection pipe fitting, wherein thermofusible spigot connection pipe fitting and embedded with metal inipple connection pipe fitting are more common.The thermofusible spigot connection pipe fitting is mainly used in the polypropylene pipe fitting and is connected with polypropylene pipe; Embedded with metal inipple connection pipe fitting is mainly used in polypropylene pipe and is connected with the tubing of metallic material, generally mostly is that thermofusible spigot connection pipe fitting and embedded with metal inipple connection pipe fitting are used when actual installation practice.The thermofusible spigot connection pipe fitting can only connect the polypropylene pipe of identical material, and certain narrow limitation is arranged; Metallic material in the embedded with metal inipple connection pipe fitting mostly is to process with copper, and this makes the manufacture cost of product be greatly improved; The electric smelting connection pipe fitting also is the polypropylene pipe that can only connect identical material, and is not having can't to realize attended operation under the situation of power supply, and is very inconvenient during use.
The model utility content
The purpose of the utility model is in order to overcome deficiency of the prior art, and a kind of easy to operate polypropylene pipe fitting that is threaded is provided.
Be to realize that above-mentioned purpose, the utility model provide a kind of polypropylene pipe fitting that is threaded, comprise the polypropylene connection pipe fitting, the two ends of said polypropylene connection pipe fitting are provided with internal thread or outside thread.
Said polypropylene connection pipe fitting is provided with fixed fitting, adapter sleeve and rotary tube piece; One end of said fixed fitting is provided with internal thread, and the outer wall of the other end is provided with the convexity that is provided with on the end inwall of protruding and adapter sleeve and flexibly connects; One end of said rotary tube piece is provided with the internal thread that is provided with on the other end inwall of outside thread and adapter sleeve and is threaded, and the end wall that rotary tube piece is threaded with adapter sleeve is provided with the circle of a depression, and a seal ring is set in the circle of said depression.
Said seal ring is a plastic ring.
The outer wall of said adapter sleeve all is set to regular polygon, and the outer wall that said fixed fitting is provided with an end of internal thread is set to regular polygon, and the outer wall that said rotary tube piece is provided with an end of internal thread is set to regular polygon.
The regular polygon of said adapter sleeve is a regualr decagon, and the regular polygon of said fixed fitting is a regualr decagon, and the regular polygon of said swivelling pipe is a regualr decagon.
The utility model beneficial effect is: the polypropylene of the utility model pipe fitting self that is threaded is provided with the pipe thread of standard; Can directly be connected with the first-class sanitaryware of the fire hose on the market; Also can be connected with the metal pipe of band pipe thread; Realize polypropylene replacement such as pipe fitting such as threaded ball valve, the loose joint metal pipe element that is threaded, reduced cost; The polypropylene pipe fitting that is threaded also can be threaded with threaded plastic tube, has broken the polypropylene pipe thermofusible spigot and has connected the Placement that is connected these two kinds of routines with electric smelting, under the situation that does not have power supply and hot-melting machine, also can be connected, and is easy to operate; The polypropylene pipe fitting that is threaded can carry out hot melt too at the plastic tube that runs into common no pipe thread and connects, and is applied widely.
Below in conjunction with accompanying drawing the polypropylene of the utility model pipe fitting that is threaded is described further.
Description of drawings
Fig. 1 is the utility model embodiment one cut-away view;
Fig. 2 is the utility model embodiment two cut-away views;
Fig. 3 is the utility model embodiment three cut-away views.
Among the figure: 1, internal thread, 2, outside thread, 3, fixed fitting, 4, adapter sleeve; 5, rotary tube piece, 6, fixed fitting is protruding, 7, adapter sleeve is protruding; 8, fixed fitting internal thread, 9, the rotary tube piece outside thread, 10, the adapter sleeve internal thread; 11, the circle of depression, 12, plastic seal ring, 13, the rotary tube piece internal thread.
Embodiment
The polypropylene pipe fitting that is threaded is that the pp material that just prepares is put into the machine material storage tube that is heated to required technological temperature, and die debugging is good, is put into the threaded fitting core rod in the mold cavity.Shut the machine safety door, pp material is injected the mold glue stomatodeum through the high-temperature fusion high pressure, to the mold cavity shunting, in the parameter of setting, carry out pressurize, melten gel, cooling after the entering glue stomatodeum through screw rod.Treat to withdraw from the core rod that is provided with pipe thread in the bellmouth position after the injection moulding cooling, die sinking is also taken off core rod, then threaded fitting is separated taking-up with core rod, promptly gets the polypropylene pipe fitting that is threaded.
Embodiment one is as shown in Figure 1, and the be threaded two ends of pipe fitting of the polypropylene of present embodiment are provided with internal thread 1.
Embodiment two is as shown in Figure 2, and the be threaded two ends of pipe fitting of the polypropylene of present embodiment are provided with outside thread 2.
Embodiment three is as shown in Figure 3, and the polypropylene of the present embodiment pipe fitting that is threaded is provided with fixed fitting 3, adapter sleeve 4 and rotary tube piece 5.One end of fixed fitting 3 is provided with fixed fitting internal thread 8, and the outer wall of the other end is provided with the adapter sleeve protruding 7 that is provided with on the end inwall of fixed fitting protruding 6 and adapter sleeve 4 and flexibly connects.One end of rotary tube piece 5 is provided with the adapter sleeve internal thread 10 that is provided with on the other end inwall of rotary tube piece outside thread 9 and adapter sleeve 4 and is threaded; The other end of rotary tube piece 5 is provided with rotary tube piece internal thread 13; The end wall that rotary tube piece 5 is threaded with adapter sleeve 4 is provided with the circle 11 of a depression, and a plastic seal ring 12 is set in the circle 11 of depression.The outer wall of the adapter sleeve 4 of present embodiment, fixed fitting 3 and swivelling pipe 5 is regualr decagon.
The polypropylene of the utility model is threaded pipe fitting owing to self be provided with the pipe thread of standard, therefore can directly be connected with the first-class sanitaryware of the fire hose on the market, also can be connected with the metal pipe of band pipe thread; Also can directly be threaded with threaded plastic tube; Also can carry out hot melt at the plastic tube that runs into common no pipe thread connects.Therefore the utility model is applied widely, easy to operate, and cost is low.
