Abstract
The utility model discloses a connecting device of a self-excitation sealing and locking pipeline. The inner wall of a connecting end socket of a pipeline is an inverted taper, a locking steel ring is arranged in the connecting end socket of the pipeline, ratchet teeth are arranged on the inner wall of the locking steel ring, the outer diameter of the locking steel ring is larger than the inner diameter of an outlet of the connecting end socket, a fully-closed rubber ring which is matched with and adapts to an inner cavity of the pipeline is arranged in the pipeline, and props against the locking steel ring, and a pressure-bearing platform is arranged at the connecting part of the rubber ring and the locking steel ring. The connecting device has the characteristics that the self-excitation locking connection is adopted, the corrosion prevention capability is good, the installation is simple and rapid, and the applicable range is wide.
Description
Technical field
The utility model belongs to the pipe joint technical field, especially relates to a kind of self-excitation sealing locking assembling pipe joint.
Background technique
At present the requirements for pipes of pipeline construction diameter 100 or more adopts groove to connect, the employing screwed connection mode below 100, and the problem of existing mode existence: the one, shock resistance is poor, be connected with groove and do not match; The 2nd, groove connects fast, and screwed connection is slow, and the cost of labour ratio is higher, and especially install such as the fire main spraying head in the place that need adjust of pipeline length, need could install several times up and down what a etc.; Commercially available low, the weak strength of fast fitting bearing capacity all can not adapt to present needs at present; Utilize the nut compressing clamp ring to carry out ways of connecting in addition, but need multiple instrument to install, bearing capacity is also lower simultaneously.
Summary of the invention
The purpose of the utility model be to improve the deficiency of prior art and provide a kind of and adopt self-excitation locking to connect, antiseptic power is good, self-excitation sealing locking assembling pipe joint simply quick, applied widely is installed.
The purpose of the utility model is achieved in that a kind of self-excitation sealing locking assembling pipe joint, is made up of pipe fitting; The connection termination inwall that is characterized in pipe fitting is a back draught, is provided with the locking steel ring in the connection termination of pipe fitting, and the inwall of locking steel ring is provided with the ratchet tooth; The external diameter of locking steel ring is greater than the internal diameter of the connection termination outlet of pipe fitting; Be provided with the totally-enclosed cushion rubber that cooperates with the tube intracavity adaptation in the pipe fitting, cushion rubber withstands the locking steel ring, and cushion rubber is provided with the pressure-bearing platform with the connection part of locking steel ring.
For the purpose that further realizes the utility model is achieved in that can be that the pressure-bearing platform of cushion rubber is extended with the pressure-bearing lip in pipe fitting.
For the purpose that further realizes the utility model is achieved in that can be that internal surface at cushion rubber is provided with the finger print lines.
For the purpose that further realizes the utility model is achieved in that can be between cushion rubber and locking steel ring, to be provided with pad.
Compared with present technology the utility model has following distinguishing feature and good effect: it is back draught that the utility model adopts the termination inwall that is connected of pipe fitting, is provided with the locking steel ring in the connection termination of pipe fitting, and the inwall of locking steel ring is provided with the ratchet tooth; The external diameter of locking steel ring is provided with the totally-enclosed cushion rubber that cooperates with the tube intracavity adaptation greater than the internal diameter of the connection termination outlet of pipe fitting in the pipe fitting, cushion rubber withstands the locking steel ring; Cushion rubber is provided with the pressure-bearing platform with the connection part of locking steel ring, and like this when the interior full of liquid of pipe fitting, fluid pressure promotes the pressure-bearing platform, the locking steel ring outwards moves; Because the effect of pipe fitting conical inboard wall causes locking steel ring clamping pipe, fluid pressure is big more; The chucking power of locking steel ring is big more, and pipeline is tight more with being connected of pipe fitting, and the ratchet tooth of locking steel ring prevents to lock the steel ring slippage; Whole erection is not wanted any instrument; And connect fast, guaranteed that the utility model can be used as the quick connection and the bigger connection occasion of pressure of larger caliber pipeline, compare with existing link have the saving of labor, laborsaving, the advantage of economizing the construction equipment instrument; Totally-enclosed cushion rubber in the while pipe fitting; Avoided contacting of liquid and pipe fitting in the pipe fitting, placement liquid can use in industries such as chemical industry, medicine, food their corrosion; The pressure-bearing platform of cushion rubber is extended with the pressure-bearing lip in pipe fitting, formed pressure tank between lip and cushion rubber, and one can utilize the pressure of liquid better; Promote steel ring locking pipeline; The 2nd, make lip tightly wale pipeline, guarantee both water-tight lock also tight of pipeline, and the big more effect of pressure is good more; Internal surface at cushion rubber is provided with the finger print lines, and having strengthened developed area has increased frictional force and sealing area; Be provided with smooth pad at cushion rubber and locking between steel ring, reduced cushion rubber and locked frictional force between the steel ring, make the steel ring can be capable of expansion and contraction.
