Abstract
A steel pipe joint which can be directly installed on a pipe without threading the pipe is mainly composed of a nut cover [6] and a pipe head [5] with external threading. The top of the nut cover is provided with a round hole; the steel pipe [1] is inserted into the nut cover [6] through the round hole, and a fixing ring [2] is adhered to the outer wall of the steel pipe [1] inserted into the nut cover [6 ]; a sealing ring (4) is sleeved on the end of the steel pipe (1) beside the fixing ring (2); the inner hole of the pipe head [5] screwed into the nut cover [6] is a bell mouth; the nut cover is screwed down, the steel pipe (1) is driven to move through the fixing ring (2), the sealing ring (4) sleeved on the end head of the steel pipe (1) is collided with the bell mouth of the pipe head (5), and the sealing ring (4) is extruded, so that the sealing purpose can be achieved.
Description
The utility model discloses a kind of pipe that not be used in and go up just direct installed steel pipe joint on pipe of threading.
Steel pipe joint commonly used at present has two kinds: a kind of is flanged joint, and another kind is a threaded joint.Use flanged joint, flange need be welded on the steel pipe; Use threaded joint, need on steel pipe, to package screw thread in advance, could connect steel pipe with threaded joint then.Be welded on the pipeline flange and, effort all more time-consuming, therefore use these two kinds of joints that steel pipe is installed at the pipeline threading, not only long in time limit, and also expense is also higher.
The purpose of this utility model is: a kind of steel pipe joint that pipe is gone up threading that not be used in is provided.Use this joint, can save effort, time-consuming cover wire process, thereby can change current steel pipe and install the time, the present situation of time-consuming, effort allows the work that steel pipe is installed become more easy, laborsaving, economical.
The purpose of this utility model is achieved in that a kind of steel pipe joint that pipe is gone up threading that not be used in, it comprises nut cap [6] and carries the tube head [5] of outer screw thread, described nut cap is screwed on the tube head [5], it is characterized in that: the top of nut cap [6] has an internal diameter only greater than the circular hole of 0.5 to 1 millimeter of steel pipe [1] external diameter; Steel pipe [1] inserts in the nut cap [6] by described circular hole, and is stained with the retainer ring [2] of 2.5 millimeters thick on steel pipe [1] outer wall in inserting nut cap [6]; On other steel pipe [1] termination of retainer ring [2], be with seal ring [4]; The described endoporus that is screwed into the tube head [5] in the nut cap [6] is a horn mouth; Fastening nut lid [6] will pass through retainer ring [2] drive steel pipe [1] and move, and the seal ring [4] that is enclosed within on steel pipe [1] termination is collided with the horn mouth of tube head [5]; Further fastening nut covers [6], and seal ring [4] will be squeezed, thereby just can reach the purpose of sealing.
Because when using the utility model that steel pipe is installed, saved effort, time-consuming cover wire process, therefore can change the present situation of current steel pipe installation fee time, effort, thereby allow the work that steel pipe is installed become more easy, laborsaving, economical.
Describe preferred embodiment of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model, a kind of upward sectional drawing of the steel pipe joint of threading of pipe that not be used in.
Fig. 2 is the schematic representation of retainer ring.
A kind of steel pipe joint that pipe is gone up threading that not be used in shown in Figure 1 is by tube head [5] be screwed in that nut cap [6] on the tube head [5] is common to be formed.The top of nut cap [6] has an internal diameter only greater than the circular hole of 0.5 to 1 millimeter of steel pipe [1] external diameter; Steel pipe [1] inserts in the nut cap [6] by described circular hole, and is stained with the retainer ring [2] of 2.5 millimeters thick on steel pipe [1] outer wall in inserting nut cap [6]; Retainer ring [2] is to stick on the steel pipe [1] with 502 glue or silicon sealant [3]; On other steel pipe [1] termination of retainer ring [2], be with seal ring [4]; Non-leakage in order to guarantee joint, seal ring [4] will be with rubber or plastics manufacturing; In order to compress seal ring [4], the described endoporus that is screwed into the tube head [5] in the nut cap [6] is a horn mouth; Like this, when fastening nut lid [6], nut cap [6] will pass through retainer ring, and [21 drive steel pipe [1] moves, and the seal ring [4] that is enclosed within on steel pipe [1] termination is collided with the horn mouth of tube head [5]; When further fastening nut covered [6], seal ring [4] will be squeezed, because the endoporus of tube head [5] is a horn mouth, thus can be stubborn more, the suffered extruding force of seal ring [4] is just big more, thereby just can reach the purpose of sealing; In like manner, allowing the hole wall at nut cap [6] top become miter angle with the central shaft in hole, also is in order to allow the hole wall at nut cap [6] top be fixed circle [2], thus just can make joint contact tightlyer with steel pipe, more firm.
Retainer ring shown in Figure 2 [2] is to be synthesized by [7] and [8] two halfround bar slices that curve with steel plate.Retainer ring [2] is synthetic with two halfround bar slices, its objective is in order to allow retainer ring [2] be convenient to stick on the steel pipe [1].
The utility model is a kind of joint, makes two logical, threeway, four-way and elbow with it, can be used for being connected of steel pipe and steel pipe, also can be used for being connected of steel pipe and valve and other pipe fitting.Simple structure of the present utility model is easy to make, and therefore, has the valve used on the steel pipe and the joint of other pipe fitting now and can change joint of the present utility model into.If all valves and other pipe fitting all adopt joint of the present utility model, those mainly are made of systems such as feedwater, heating, chemical industry steel pipe installation will become more easy, laborsaving, save money.
