Abstract
The utility model relates to a quick pipe-joint. An inner joint is sheathed with a hose which is tightly clamped from outside with a pipe hoop. An outer joint is provided with inner screw-threads and is screwed up with a hard tube. The outer surface of the device is provided with a pair of ear seats and is penetrated through by a hinge pin so as to be connected with a clamping rod. Approaching to the hinge pin, the ends of the two clamping rods are processed into cam-shaped curved surfaces and are arranged inside a groove of the wall of the outer joint. With the cam-shaped curved surfaces of the two clamping rods, the inner joint is tightly abutted with a sealing rubber ring arranged at the end surface inside the outer joint. The pipe-joint has the advantages of quick assembling and disassembling, reliable connection, high-pressure resistant and a long service life.
Description
The utility model belongs to the industrial pipeline annex.
Industrial have a lot of water pipes, tracheae and an oil pipe, and they all need pipe coupling, especially resemble Iron And Steel Plant, all use thousands of pipe coupling on every blast furnace.Fluid often has pressure in the pipeline, needs regular cleaning again, therefore needs frequent dismounting.Because the objective circumstances such as urgent of the inclement condition of stokehold work or fire-fighting task are arranged, this pipe coupling often requirement can fast assembling-disassembling, and assembling is also very reliable.At present, domestic steel industry is all used the ball type joint that hydraulic pipe line is used.One circle groove is arranged on the spigot of this joint, and row's ball is arranged in the socket, have steel bushing to entangle outside it, promote steel bushing each ball to be pressed in the groove of spigot, block spigot; Only need when taking apart to push steel bushing to spring one side, ball can freely unclamp.So, socket was deviate from this device play a part to prevent by ball, but structure itself can not provide enough pressure, seal ring between interior socket is compressed, therefore often spill high pressure water, and effort, time-consuming is installed, the very big axial force of 2-3 human to hold out against, ball could be pressed in the groove then, overall process needs just can finish more than 60 seconds.Owing to leaking and causing that the steel part rust in the joint is dead, joint is difficult for splitting out, and also is difficult to reinstall therefore this joint life-span, very waste for once.
The purpose of this utility model is will provide a kind of easily to adorn fast, and voltage endurance capability is strong, can nonexpondable pipe joint unit.
The purpose of this utility model is achieved in that joint is made up of spigot, pipe collar and socket 3 parts, seal ring is housed in the socket, and has internal thread and hard tube to tighten, spigot then with the flexible pipe suit after the tube hoop from outer grip both hose.Locate respectively to cast out 1 pair of ear seat at the socket outer surface for relative 180 ° along circumference, the every pair of ear seat has hinge pin to pass and connects a kelly, spanner one end of these 2 kellies all is exposed at outside the joint, and another nearly hinge pin end then is processed into cam curved surface shape, and it is contained in the groove of socket wall.Kelly has 2 positions: 2 kellies of the first are and close up state, longitudinal axis along joint is poured on the socket outer surface, at this moment the cam curved surface of 2 kellies enters the neck ditch of spigot and it is held out against on the end-face seal ring in socket, and this is the working state of joint; Another is the open-shaped attitude of kelly, stands on outside the joint, and at this moment the cam curved surface of kelly breaks away from the neck ditch on the spigot, and this is the disassembly status of joint.
The utility model is owing to axially hold out against by the cam curved surface on the kelly, pine when therefore installing, and both leicht fallen D/A during operation, very fast again, can finish 1 installation 5 seconds; Because the cam curved surface pressure is very big, makes end face seal very reliable, withstand voltage height; Because non-leakage, the corrosion of just having exempted joint is stuck, through testing this joint working life above 100 times.
Below described as embodiment of the present utility model with 1 inch pipe joint structure.
Present specification has 2 width of cloth accompanying drawings, and Fig. 1 is the working state erection drawing of joint, represents with sectional view; Fig. 2 is its disassembly status plan view.
Describe structure and working condition in detail below in conjunction with accompanying drawing.
Remove among Fig. 1 outside flexible pipe (1) and the hard tube (10), all are body portions of these piecing devices, wherein (2) are spigots, suit flexible pipe (1) on it, and its right-hand member has an annular neck ditch, the diagram spigot is contained in the socket (9), its right side heads on O-ring seal (7), it is killed on the step surface in socket, and (4) are two pipe collars, with 4 bolts (3) grip both hose, on the socket outer surface, locate 2 pairs of ear seats (5) that cast out for relative 180 °, every pair is installed with a hinge pin (6) and links to each other with kelly (8), and the socket right-hand member links to each other with hard tube by internal thread (12).(13) are the spanner ends of kelly among the figure, and (11) then are the cam curved surface ends of kelly.
2 kellies are and close up state among Fig. 1, at this moment its cam curved surface end tightly the spigot dieback on O-ring seal, 2 open-shaped attitudes of kelly among Fig. 2, at this moment its cam curved surface end perk, left the annular neck ditch of spigot right-hand member, thereby interior socket can be thrown off.
Reliable in order to connect between socket in making, can not leak, and dismounting easily, key be 2 on the kelly cam curved surface and the effect of the annular neck ditch of spigot right-hand member.For 1 inch pipeline, the transverse section of the neck ditch among Fig. 1 on the spigot is that radius is 10.75 millimeters a circular arc, cam curved surface on the kelly then is made up of 13 coordinate points in the following table, 13 scale division values in the table are the center with the hinge pin hole all, and be 0 ° of tolerance with the opposite direction that parallels with the kelly longitudinal axis, in the table unit of each radius vector all is millimeters:
| Scale division value | 0° | 15° | 30° | 45° | 60° | 75° | 90° |
| Radius vector | 6.04 | 7.07 | 8.06 | 9.10 | 9.95 | 10.61 | 11.07 |
| Scale division value | 105° | 120° | 135° | 150° | 165° | 180° | |
| Radius vector | 11.09 | 11.24 | 11.37 | 11.50 | 11.62 | 11.75 |
What be contained in the step front in the socket is the end-face seal ring of square section.
Fig. 2 shows that the profile of socket is 8 dihedrals, also can be with 6 jiaos or 12 jiaos.
