Abstract
The pressure self-locking joint of the utility model relates to the improvement of a sealing joint for fluid pipelines. The pressure self-locking joint is characterized in that both ends of a joint pipe body are respectively provided with two rubber sealing rings inside; the inner wall of the joint pipe body is provided with a pressurized liquid flowing channel; both end faces of the joint pipe body are respectively provided with a convex step and two screw nuts. When the utility model is used for sealing and connecting pipes, no outer screw thread is manufactured at the ends of the pipes. The pipes can be sealed and connected as long as being inserted into the joint. The utility model has the advantages of easy installation, material saving, labor saving and time saving.
Description
The utility model is a kind of fluid pressure in the pipeline that utilizes, be during pipeline connects without screw thread from latching connector.
Liquid conducting pipes at first will around flax silk, be coated with white paint at pipeline head threading, or around four fluorine ethylene bands, screw in female pipe joint then by dress, maintenance on outside thread, finish being tightly connected.Find that in by the pipeline that installs seepage need keep in repair, or will open interface in addition on pipeline the time, construction as stated above promptly exists the difficulty of threading, the rotation that pipeline can't be done to screw.Present method of construction is that pipeline is clipped one section, uses by order to connect.By order is that groove is filled on the boss rank, the device that screws with nut.Use by order and will inevitably stay the boss rank to fill in the gap of groove by dress, the former pipeline thread that stretches when nut screws has destroyed the performance that is tightly connected of former pipeline.
The utility model is to utilize fluid pressure in the pipeline, make that seal for pipe joints connects without nut connector, it can or be opened in the interface procedure in addition in the maintenance of former pipeline, can keep the being tightly connected property of former pipeline, and has solved pipeline and destroy the internuncial problem of seal for pipe joints because of expanding with heat and contract with cold.
The purpose of this utility model is achieved in that in these novel joint body two ends rubber seal is housed, and two end nuts compress seal ring and form end face seal, and pipeline is filled in seal ring and can be realized being tightly connected.When pipeline pressure to the effect of seal ring external diameter, the then fastening outer diameter tube of seal ring forms self-locking seal and connects.
The utility model is because of being equipped with rubber seal in the body, pipeline does not need threading during by dress, and pipeline needs only relative insertion when connecting and can be tightly connected, and is simple especially by dress.Because the seal ring external diameter is subjected to the fastening outer diameter tube of pipeline pressure self-locking, reliable performance is tightly connected.
Concrete structure of the present utility model is provided by accompanying drawing.
Fig. 1 is the sectional drawing according to the pressure self-locking joint that the utility model proposes, and illustrates according to the working condition that the utility model proposes below in conjunction with Fig. 1.
This joint comprises body (5), and inboard wall of tube body has four flow of fluid grooves (1), and seal ring (6) is close to body end face boss rank (3), and nut (4) is arranged.
Nut (4) compresses " L " seal ring (6) and becomes end face seal with boss rank (3) in the drawings, and two pipelines (2) insert internal diameter of the seal ring and the outer diameter tube state that becomes to be tightly connected relatively.Fluid pressure raises in pipeline, its liquid by flow of fluid groove (1) with propagation of pressure to seal ring (6) external diameter, make the fastening outer diameter tube of seal ring form two seals for pipe joints and connect.
Claims (3)
1, the pressure self-locking joint is the cylinder type joint of pipeline of being tightly connected, and this joint has two nuts (4) by body (5) two ends, it is characterized in that in body (5) two ends two " L " rubber seal (6) being housed.
2, pressure self-locking joint according to claim 1, it is characterized in that in body (5) two ends two " L " rubber seal (6) being housed, pipeline (2) inserts seal ring (6), and pressured fluid is fastening to the self-locking of " L " seal ring external diameter by inboard wall of tube body flow of fluid groove (1).
3, pressure self-locking joint according to claim 1 is characterized in that in body (5) two ends two " L " rubber seal (6) being housed, and body (5) end face has boss rank (3) to be compacted into end face seal through nut (4).
