Abstract
A flexible tube sealing connection head comprises a head-connection seat, a head-connecting screw female and a round sealing ring that is arranged in the head-connection seat, which is characterized in that a sealing conduit that is used for inserting the flexible tubes is connected in the inner end of the head-connecting seat, which prevents the end portion of the flexible tube raidally deforming after pressed, under the circumstance gaps do not come into being between the flexible tubes and the sealing ring, thereby the sealing connections between the flexible tubes is realized. The design of the flexible tube sealing connection head is scientific, the conformation is reasonable and simple, the excellent performance of sealing is capable of meeting the connections among various engineering plastic flexible tube and is applicable to the connections between flexible and hard tube.
Description
Technical field
The utility model relates to pipe fittings, especially a kind of flexible pipe head that is tightly connected.
Technical background
Flexible pipe uses very extensive as the delivery line of various fluids in fields such as industry and lives.At present, the pipe joint structure that is used for connecting between flexible pipe is fairly simple, by connection block, Female connector fittings and the O-ring seal that sets within it are formed, connection block is threaded with Female connector fittings, during use, one end of flexible pipe is nested with on connection block in the mode of being sealed and matched, an end that is connected flexible pipe is after the Female connector fittings insertion, O-ring seal is nested with the hose end that is being inserted into, the connection block that will be installed in hose end this moment docks with the Female connector fittings that is connected hose end, along with connection block constantly screws in Female connector fittings, the seal ring that the end face of connection block will be oppressed in the Female connector fittings makes its distortion, because the outer ring of described seal ring is subjected to the Female connector fittings inner wall limit, the seal ring behind the pressurized can only inwardly expand anchor ear in flexible pipe, thereby realizes the connection between flexible pipe.Yet in actual use, it is found that because the characteristic of hose material, the seal ring squeezing action is connected hose end owing to can be out of shape, be easy to generate the gap between hose end after the distortion and seal ring, thereby make that the sealing of flexible pipe in the joint joint is low usually poor, can not satisfy the seal request that engineering is used, especially for use in having seepage and having on the liquid transmission pipeline of uniform temperature, because the seepage of connecting head can pollute between pipeline, influences environment.
Summary of the invention
The purpose of this utility model is the deficiency that exists at the aforementioned tube joint, and a kind of good seal performance is provided, the flexible pipe applied widely head that is tightly connected.
The utility model flexible pipe head that is tightly connected, comprising: connection block, Female connector fittings and the O-ring seal that sets within it is characterized in that: described connection block the inner is provided with for being connect the sealing duct that flexible pipe inserts.
Be tightly connected another feature of head of the utility model flexible pipe is: outer ring, O-ring seal two ends is provided with the taper chamfering, and the inner anchor ring of connection block ring surface and Female connector fittings is respectively equipped with and the corresponding conical surface of O-ring seal taper chamfering.
Described flexible pipe be tightly connected the head big I design as required.
The be tightly connected design principle of head of the utility model flexible pipe is: utilize conduit to insert and be connected hose end, to prevent to be connected radial deformation behind the hose end pressurized, when connection block and Female connector fittings screw be connected after, be arranged on the seal ring compressive deformation between connection block end face and Female connector fittings interior edge face general, owing to connect and be inserted with conduit in the hose end, seal ring behind the pressurized can not force quilt to connect the flexible pipe radial deformation, can only make its more closely anchor ear on flexible pipe, cooperating between the seal ring under this state and the flexible pipe that is inserted with conduit, can not produce the gap between flexible pipe and seal ring, thereby realize being tightly connected between flexible pipe.
The utility model flexible pipe design science that is tightly connected, rational in infrastructure, simple, its excellent sealing performance can satisfy the connection between various engineering plastics flexible pipes, also is applicable to being connected between flexible pipe and stereoplasm tube.
The utility model flexible pipe be tightly connected the head concrete structure provide in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 be flexible pipe be tightly connected the head structural representation.
Embodiment
Embodiment: can be clear that from Fig. 1, flexible pipe be tightly connected the head form by connection block 1, Female connector fittings 2 and O-ring seal 3, the outer end of connection block 1 is provided with pipe and inserts termination 11, the inner of connection block 1 is provided with for being connect the sealing duct 12 that flexible pipe inserts, the stage casing of connection block 1 is provided with the screw thread 13 that can be connected with Female connector fittings 2, and the inner anchor ring of connection block 1 is provided with taper circular groove 14; Described Female connector fittings 2 internal spherical surfaces are tapering surface 21; Described O-ring seal 3 both ends of the surface are respectively equipped with and connection block 1 taper circular groove 14 and Female connector fittings 2 tapering surfaces 21 corresponding taper chamfer surfaces 31,32.
The be tightly connected using method of head of the utility model flexible pipe is: select for use and the corresponding flexible pipe of the flexible pipe specification head that is tightly connected, elder generation inserts connection block 1 with an end flexible pipe in the drive fit mode insertion termination 11, Female connector fittings 2 and O-ring seal 3 be nested with successively be connected on the flexible pipe 4, sealing duct 12 insertions with connection block 1 are connected flexible pipe 4 then, to be enclosed within the O-ring seal 3 that is connected on the flexible pipe 4 again and be pushed into connection block 1 taper circular groove 14 places, the taper chamfer surface 31 of O-ring seal 3 is contacted with connection block taper circular groove 14, at this moment, connection block 1 and Female connector fittings 2 are connected by screw thread, tighten Female connector fittings 2 and make and be connected flexible pipe 4 and closely be connected with connection block 1.Because the possibility that radial dimension changes behind flexible pipe 4 pressurizeds of joint, has been eliminated in the sealing duct 12 of connection block 1 and O-ring seal 3 in flexible pipe 4 restriction radially, guaranteed the sealing of joint and flexible pipe junction.The flexible pipe of this structure head that is tightly connected also can overcome the flexible pipe temperature influence and the dimensional changes that produces, has guaranteed the sealing of joint and flexible pipe junction.
