Abstract
The utility model discloses a pipeline connecting device of branching water-supply equipment. The pipeline connecting device is composed of a branching water-supply device body, a pressure reduction buffer sealing ring, a water outlet, a taper sliding pressure sealing pipe core, a locking nut, a water pipe and a sliding pressure locking ring. The pipeline connecting device of the branching water-supply equipment is characterized in that the pressure reduction buffer sealing ring is arranged on one side of the taper sliding pressure sealing pipe core, the taper sliding pressure sealing pipe core is fixed to the water outlet of the branching water-supply device body through the locking nut, the water pipe is connected to the other end of the taper sliding pressure sealing pipe core, the taper sliding pressure sealing pipe core is sleeved with a pipe opening of the water pipe in the mode that the pipe opening is expanded by a pair of flaring pliers or mouth opening pliers, the water pipe is sleeved with the sliding pressure locking ring, and the sliding pressure locking ring is in sliding fit with the water pipe. The pipeline connecting device of the branching water-supply equipment has the advantages that connection is fitter and firmer through pressurization of the locking nut, the sealing performance is stronger, connection is safer and more reliable, maintenance is easier, and the safety dangers of the branching water-supply equipment are thoroughly avoided.
Description
Technical field
The utility model relates to a kind of pipeline connecting device, belongs to heating and ventilating equipment accessory, especially a kind of pipeline connecting device of branching supply water equipment.
Background technique
Along with water floor heating, radiator constantly rise, domestic water, hot and cold water equipment constantly increase.Branching supply water device is extensive use thereupon also.But existing branching supply water device connecting pipeline is to use nut to compress scalable ring, in scalable hoop, slides, and makes the scalable tight tube wall of encircling.Produce to press down simultaneously and seal up connection mouth.Under long term high temperature high pressure, use tubing softening transform.Scalable ring loses tube wall tensioner internal stress, makes nut loosening, the slighter vibrations that produce under High Temperature High Pressure effect due to pipeline, has accelerated nut loosening, and joint tighness is declined, and pipe comes off.Directly causing infiltration to leak, causing any property loss, personal injury.Although this connection is convenient to safeguard, life cycle, maintenance period are short very dangerous.A lot of products are used rubber as Sealing.It is also one of the reason of infiltration of leaking that rubber has certain digestion period (4-5).
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, a kind of pipeline connecting device of branching supply water equipment is provided, this device is pressurizeed and is made to connect more laminating, more firm by locking nut, sealability is strong, connect safer, reliable, maintenance and repair is also relatively simple, thoroughly solves the safe suffering of branching supply water equipment.
The technical solution of the utility model is: a kind of pipeline connecting device of branching supply water equipment, by branching supply water device main body, pressure cushion seal circle, water outlet, tapering sliding pressure sealed core, locking nut, water pipe, sliding pressure locking ring, formed, it is characterized in that: the side at tapering sliding pressure sealing tube core is provided with pressure-reducing cushioning seal ring, the water outlet of branching supply water device main body is inserted in one end of tapering sliding pressure sealing tube core band pressure-reducing cushioning seal ring, and by locking nut, tapering sliding pressure sealing tube core is fixed on the water outlet of branching supply water device main body.At the other end connecting water pipe of tapering sliding pressure sealing tube core, water pipe clamps by enlarging or open mouth tongs enlarging is sleeved on tapering sliding pressure sealing tube core.On water pipe, be set with sliding pressure locking ring, sliding pressure locking ring set is expressed to sliding pressure locking ring by special pressure setting tool the end of water pipe, and sliding pressure locking ring becomes to be slidably matched with water pipe.
Described tapering sliding pressure sealing tube core is that brass material is made, and diameter dimension is slightly larger than in pipeline through 1-2 millimeter.
Described locking nut is locking separately, adopts copper product or Steel material to make.
Described pressure-reducing cushioning seal ring adopts polyurethane material to make.
Described sliding pressure locking ring adopts copper product or Steel material to make.
Described special pressure setting tool is known prior art.
Owing to adopting technique scheme, the novel beneficial effect of this reality is: this pipeline connecting device has effectively avoided tubing to be subject to the physical change under High Temperature High Pressure, has influence on locking nut.Under the effect compressing of locking nut, surface of contact produces seamless combination, and combination seal degree is good, and voltage endurance capability is strong.Utilize the feature that tubing toughness is large, by instrument, pressurize and make it to be closely connected with water pipe is independent.Use the tubing of this device as PEX, the plastic tubes such as PB are more suitable for, and tubing can not be subject to its impact in high temperature and high pressure environment, can closely be connected with branching supply water equipment separately.Two kinds of connections do not interfere with each other, and connect safety and reliability, and maintenance and repair is also relatively simple.Pipeline connects to adopt to block presses, and by outside forceful action, makes tubing be out of shape in advance fastening interface, utilizes the pliability of plastic tube, the characteristic of resilience to form permanent firm connection, and the combination of two kinds of connections thoroughly solves the safe suffering of branching supply water equipment.
