Abstract
The utility model relates to a low pressure flexible pipe joint. The existing joint has the disadvantage of inconvenient use. The utility model is composed of an outer screw thread sleeve, a hollow inner screw thread sleeve, a lock ring type slide casting die, an inner expanding sleeve, and a rubber washer. The utility model is characterized in that the utility model is sealed by the inner expansion and outer pressure and is connected by screw threads. A flexible pipe which needs to be connected is inserted into one side of the inner screw thread sleeve. The end of an easy expanding flexible pipe is inserted with the inner expanding sleeve. A lock ring type slide casting die is sheathed on the flexible pipe. The end of the other flexible pipe which has the inner expanding sleeve and the lock ring type slide casting die and the rubber washer are tightly screwed on the both ends by the outer screw thread sleeve. The joint can be in repeatable use. The utility model is suitable for the joint of flexible pipes with easy expansion pipe diameters and the butt-joint of flexible pipes with the same diameter or different diameters.
Description
The utility model relates to a kind of hose coupling, and it is fastening to belong to the pipeline butt joint, the hardware technical field.
Existing low pressure hose coupling, as convex tendon type, wave-like type, sawtooth pattern, fluted body, withhold type etc., in the place of more use low pressure hose, people are using and are easily expanding the caliber sebific duct.Owing to always adopt free plug-type sebific duct butt joint (wave-like type or sawtooth pattern), often cause the defect of the easy landing of sebific duct, though adding wire tightens or clamps with clip, but still the phenomenon of unresolved landing sometimes and leakage, if different just more difficult butt joints of caliber, adopt other rubber hose coupling, use very inconveniently, and effect is uncertain good.That announces for Chinese patent CN2130999Y number is how structurally more approaching with hose coupling and the utility model.It is a kind of novel assembling type rubber hose coupling, but following defective is arranged, many hollow Taper Pipes with hose coupling have only part to contact with sebific duct, the hollow cone bore is much smaller than the sebific duct internal diameter, so just influencing liquid stream normally passes through, must increase a main part when docking sebific duct in addition and change another main part and could dock, thereby bring the not good of inconvenient and effect.
The purpose of this utility model is that the defective that is to overcome existing joint provides a kind of convenient and practical, the union in the hot-water heating pipe fitting again of its function, the sebific duct union of the detachable use of low pressure.
The purpose of this utility model is achieved in that
This hose coupling is by external thread sleeve, hollow inner screw sheath, retainer formula sliding pressure part and rubber washer are formed, when butt joint is easily expanded the caliber sebific duct, sebific duct by the company for the treatment of inserts from hollow interior swivel nut left side, insert the easily termination of expansion flexible pipe from the right side with inner expension cap, put retainer formula sliding pressure part, set up rubber washer and another is equipped with the flexible pipe termination of inner expension cap and sliding pressure part, with external thread sleeve both ends of the surface are tightened together, tighten and get final product, because the cylindrical female cover is provided with fine thread with external thread sleeve or pipe thread can screw.So by screwing the tension of the large end face of two inner expension caps of internal and external screw thread cover, achieved the goal by rubber ring seal in the centre.
Inner expension cap is to be made of a columniform eyelet, in be provided with fine thread or pipe thread and cooperate with inner diameter.External thread sleeve can be hexagon also can be cylinder annular knurl shape.
The utlity model has following advantage:
1, the inner expension cap outer surface that enters sebific duct part contacts entirely with sebific duct, and the inner expension cap internal diameter is not less than the sebific duct internal diameter, does not influence liquid and flows.
2, the utility model need not change part and increase appliance and can be connected, external thread sleeve, inner screw sheath, interior long cover, rubber gas ket with sebific duct can with have corresponding valve or the device blood interface that screws screw thread, realize that the soft or hard pipe connects.
3, but detachable use of the utility model or other part are used in combination also repeat function, and be fast convenient.
4, joint can be divided into 2 assemblies and be connected use respectively with respective tube.
5, joint can make the flexible pipe of kind different size or different tube diameters achieve a butt joint.
Description of drawings:
Fig. 1 the utility model schematic representation
Fig. 2 treats the connection diagram of jointed tubular workpieces and thread bush assembly
Fig. 3 treats the connection diagram of joint and hollow inner screw sheath assembly
(1) jointed tubular workpieces, (8) joint to be connect are treated in the easy expansion of the company for the treatment of caliber sebific duct, (2) hollow inner screw sheath, (3) retainer formula sliding pressure part, (4) external thread sleeve, (5) rubber washer, (6) inner expension cap, (7).
Embodiment is described further below in conjunction with accompanying drawing:
As shown in Figure 1, 2, 3, the company for the treatment of easily expansion caliber sebific duct (1) inserts from hollow inner screw sheath (2) left side, inner expension cap (6) is inserted in the sebific duct termination, (or truncated cone shell type) the sliding pressure part of retainer formula on the sebific duct end headgear (3), the sebific duct termination that inner expension cap (6) and retainer formula sliding pressure part (3) are housed with the caliber sebific duct termination of another company for the treatment of again; Between the large end face of two inner expension caps, put folder rubber washer (5), screw to tighten with external thread sleeve (4) connection and get final product.
When the utility model uses, as if using an end inner expension cap instead or changing an end sliding pressure cover and inner expension cap or two ends and use inner expension cap instead, or one end use inner expension cap instead, one end is used the sliding pressure cover instead, then can make the utility model realize easily expansion caliber sebific duct different bores of the same type, dissimilar different bores, dissimilar butt joints with bore.This practicality is newly in frequent dismounting, the easily place of expansion caliber sebific duct is used in tipping, can achieve a butt joint very easily, realize docking with the through hole of device blood, hole, pipe, as tubular member, low pressure vessel detects place, building site, often the dietetic hygiene place of flushing environment often adds place with the dismounting aqueduct or the like temporarily.
Claims (2)
1, a kind of low-pressure hose connector, form by external thread sleeve, hollow inner screw sheath, retainer formula sliding pressure part and rubber washer, it is characterized in that: in the termination of easy expansion flexible pipe, be provided with an inner expension cap and be located at the retainer formula sliding pressure part on the flexible pipe termination and between the large end face of two inner expension caps, be provided with the rubber gas ket.
2, joint according to claim 1 is characterized in that: inner expension cap is a columniform eyelet, in be provided with fine thread or pipe thread and cooperate with inner diameter.
