Description

The pipeline plug assembly

The utility model relates to gas, liquid pipe-line system field, particularly a kind of pipeline plug assembly.

Existing pipeline plug assembly as Fig. 5, shown in Figure 6, is made up of socket 1, sliding sleeve 5, plug 2.Be provided with ball 19 in the hole 22 on the socket 1.(see figure 5) when plug assembly is in coupled situation, ball 19 withstand on the inwall 24 of sliding sleeve 5, and are stuck in the circular groove 23 on the plug 2, and plug 2 can not be extracted.Spring 4 is pushed down sliding sleeve 5 to the right, and the snap ring 20 on the socket 6 withstands the inner conical surface 21 of sliding sleeve 5, and sliding sleeve 5 can not be deviate from from socket 6.(see figure 6) when plug 2 inserts and extracts must be moved to the left pressure spring 4 with sliding sleeve 5 earlier, makes ball 19 return inner conical surface 21 from inwall 24, thereby ball 19 can be stepped down to periphery, and then plug 2 is inserted or extracts.After plug 2 inserts or breaks away from socket 6, loosen sliding sleeve 5 again, under the pressure of spring 4, sliding sleeve moves right, and ball 19 is inwardly return under the guiding of inner conical surface 21 in the inwall 18 of sliding sleeve 5.This shows, use the action of existing pipeline plug assembly as follows: pushing sliding sleeve → insertion (or extracting) plug → loosen sliding sleeve.Promptly need to carry out 3 actions and can finish the operation of pegging graft, therefore, common people's unexplained reference can not finely be operated, and act of operation is slow.

The purpose of this utility model is to provide a kind of operation simple and easy, pipeline plug assembly fast.

The utility model is realized in the following way: this pipeline plug assembly comprises socket, sliding sleeve, plug, seal ring.Sliding sleeve is enclosed within on the socket, and spring 4 is arranged between the two.Sliding sleeve is provided with cavity in the inwall of plug entry end.Have at least one radial groove on the socket, elastic hook is housed in the groove.Elastic hook radially withstands on the sliding sleeve, axially withstands on the socket, and has protuberance to be stuck on the boss of socket.Plug is provided with convex shoulder, so that can block elastic hook after insertion.Sliding sleeve one end is provided with reed, on the shaft shoulder that withstands on receptacle ends.Socket is provided with the shoulder block for the sliding sleeve axially locating.

During grafting, grab on the other hand sliding sleeve,,, make the convex shoulder on the plug pass through hook portion smoothly because elastic hook can resiliently deformable on the other hand with the plug insertion socket endoporus, cross hook portion after, hook just resiles.Under the effect of spring, hook portion is blocked by convex shoulder, hook radially withstand sliding sleeve, axially withstand socket, this moment, plug assembly promptly was in coupled condition.When needs are extracted plug, grab sliding sleeve on the other hand, on the other hand plug to be pulled out, this moment, the sliding sleeve end withstood on the shoulder block of socket, and hook can not deviate from.Simultaneously, the sliding sleeve pressure spring oppositely moves relative to plug, and gib head just can be inserted in the cavity of sliding sleeve, and the protuberance of hook then is stuck on the boss of socket, thereby plug can be extracted smoothly.In the moment that plug is extracted, under the effect of spring, sliding sleeve moves relative to socket, and gib head is depressed, and the reed of sliding sleeve end withstands on receptacle ends, is returned to separated state.This shows that no matter this plug assembly is to insert the operation that connects or extract separation all only to need once action just can finish, thereby reach simple to operate, purpose fast.

The utility model has the advantages that: operate simple and easy, convenience, can increase work efficiency greatly.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

With reference to Fig. 1, Fig. 4, this pipeline plug assembly is made up of socket 6, sliding sleeve 5, plug 2, elastic hook 1, seal ring 3.Plug 2 and socket 6 connect with pipe with internal thread or outside thread respectively.Sliding sleeve 5 is enclosed within on the socket 6, and spring 4 is arranged between the two.Sliding sleeve 5 is provided with cylindrical cavity 16 in the inwall of plug entry end, also can be the truncated cone shape cavity, or other shapes can be held the cavity of the head 9 of elastic hook 1.Elastic hook 1 is arranged in the radial groove 18 on the socket 6.Radial groove 18 can have 1 or several.Elastic hook 1 has been provided with the hook spring 13 of resiliently deformable effect.There is convex shoulder 7 to block the hook portion 8 of hook 1 on the plug 2.The head 9 of hook 1 radially is stuck on the sliding sleeve 5, axially is stuck on the socket 6, make socket 6 and plug 2 not can because of be bullied, hydraulic coupling and external broach separate both.Seal ring 3 is arranged on close insertion end place on the plug 2, seals at

plug

2 and 6 of sockets.

With reference to Fig. 2, grab sliding sleeve 5 on the other hand, when grabbing in the plug 2 insertion sockets 6 on the other hand, convex shoulder 7 is pressed on the elastic hook 1 on the plug 2, makes hook spring 13 distortion of hook 1, thereby makes plug 2 can insert the endoporus of socket 6 smoothly.The hook portion 8 of hook 1 withstands on the trough rim 12 of socket 6, and hook 1 can not be moved to the left, and after plug 2 inserted and makes convex shoulder 7 cross hook portion 8, hook spring 13 resiled, and is returned to coupled situation shown in Figure 4.

With reference to Fig. 3, when grabbing on the other hand sliding sleeve 5, grab plug 2 on the other hand when extracting socket 6, sliding sleeve 5 pressure springs 4, the sliding sleeve left end withstands on the shoulder block 17 of socket 6, makes sliding sleeve 5 location, and hook 1 can all not expose and drop out, and this moment, sliding sleeve 5 was abdicated space 16 at hook 1 head 9 places.Hook 1 is under the drive of plug 2, and its protuberance 15 is stuck in rotation on the boss 14 of socket 6, makes head 9 insert the cavity 16 of sliding sleeve, and hook 1 is outwards stepped down, thereby plug 2 can be extracted smoothly.Plug 2 is extracted moment, and under the effect of spring 4, sliding sleeve 5 relative sockets 6 move to right, and hook 1 head 9 is depressed, and the reed 11 on the sliding sleeve 5 withstands on the shaft shoulder 10 of socket 6, gets back to state shown in Figure 1.
