Abstract
The invention relates to a pneumatic seal joint assembly consisting of a cone-shaped compression barrel, an O-shaped rubber seal ring, a cone-shaped inner bamboo joint-like cutting sleeve, a deformed rubber seal ring and a guide sleeve. The cone-shaped inner bamboo joint-like cutting sleeve is matched on the inner wall of the cone-shaped compression barrel and arranged between the cone-shaped compression barrel and the guide sleeve on the deformed rubber seal ring in a reversed prick manner. The O-shaped rubber seal ring is arranged on the cone-shaped compression barrel. The invention has few parts, good seal performance and is simpler and more convenient to maintain and replaces original multifarious variety with few variety. The invention has good interchangeability and can be completely interchanged with existing quick connecting joint assembly, thereby reducing the production and processing cost and the weight of the pipe assembly, improving the reliability of the quick connecting joint and increasing the economic benefits.
Description
Technical field
The present invention relates to a kind of pneumostop connector assembly, belong to the technical field of pneumostop joint.
Background technique
At present, the pneumostop joint is widely used in the Automobile air brake field.The pneumostop joint mainly is divided into common cutting ferrule nut thread and connects and the fast slotting two kinds of structures that are connected.Common cutting ferrule nut thread connects the requirement of operator's skills involved in the labour very high, and sealing is relatively poor relatively.Fast inserting structure is divided into two kinds of the fast inserting structures of fast inserting structure of VOSS company and MSC company, is characterized in simple to operate, good seal performance.Respectively become one between two kinds of fast inserting structures, can not exchange, cost of material is also relative with processing cost higher.At present, on the liberation truck of a vapour and the fertile truck of heavy vapour person of outstanding talent, employing all be the fast inserting structure of VOSS company, be the fast inserting structure of male and female connector to inserting, complex structure, cost is higher, maintenance is inconvenient, and is various in style, the corresponding a plurality of kinds of a kind of caliber.
Summary of the invention
The object of the present invention is to provide a kind of novel pneumatic SEALING FITTING assembly, it is simple in structure, and is easy to maintenance, good airproof performance.
Technological scheme of the present invention is achieved in that a kind of pneumostop connector assembly, form by tapered gland nut, O type rubber seal, tapered interior ring cutting ferrule, special-shaped rubber seal, guide sleeve, it is characterized in that: on tapered gland nut inwall, be combined with tapered in the ring cutting ferrule, the ring cutting ferrule is arranged on the special-shaped rubber seal between tapered gland nut and guide sleeve in tapered, the ring cutting ferrule arranges that for the hangnail ring O type rubber seal is located on the tapered gland nut in tapered.
Described special-shaped rubber seal is through on the guide sleeve, has the draw-in groove that holds the guide sleeve footing and the seal ring of interior outer lug.
Described guide sleeve has the thick little tapering in thin bottom, top, and the bottom has the planar annular footing, and footing is enclosed within the draw-in groove of special-shaped rubber seal.
Described tapered gland nut has outside thread, and inside has the thick tapering in thin bottom, top.
Good effect of the present invention is: combine existing fast advantage of inserting sealing configuration and cutting ferrule nut thread sealing configuration, SEALING FITTING assembly number of spare parts still less; Sealability is better; Keep in repair more simple and conveniently, replace original numerous and diverse kind with less kind; Interchangeability is good, can exchange fully with existing quick inserting joint assembly, has reduced the weight of production and processing cost and tube bank assembly, has improved the reliability of quick inserting joint, has increased economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing: as shown in Figure 1, a kind of pneumostop connector assembly, form by tapered gland nut 2, O type rubber seal 3, tapered interior ring cutting ferrule 4, special-shaped rubber seal 6, guide sleeve 5, it is characterized in that: on tapered gland nut 2 inwalls, be combined with tapered in the ring cutting ferrule, the ring cutting ferrule is arranged on the special-shaped rubber seal 6 between tapered gland nut 2 and guide sleeve 5 in tapered, ring cutting ferrule 4 arranges that for the hangnail ring O type rubber seal 3 is located on the tapered gland nut 2 in tapered.
Described special-shaped rubber seal is through on the guide sleeve, has the draw-in groove that holds the guide sleeve footing and the seal ring of interior outer lug, and bigger elasticity is arranged in the axial direction, allows special-shaped rubber seal that a spot of displacement is arranged in the axial direction.
Described guide sleeve has the thick little tapering in thin bottom, top, the bottom has the planar annular footing, and footing is enclosed within the draw-in groove of special-shaped rubber seal, before swivel nut is not tightened, nylon tube can be inserted between guide sleeve and the special-shaped rubber seal easily through the open cutting ferrule of internal diameter.
Described tapered gland nut has outside thread, and inside has the thick tapering in thin bottom, top.
As shown in Figure 1, before tapered gland nut 2 is not tightened, ring cutting ferrule 4 initial open configuration internal diameters are greater than the nylon tube external diameter in tapered, and nylon tube 1 is inserted between guide sleeve 5 and the special-shaped rubber seal 6 easily through the open tapered interior ring cutting ferrule 4 of internal diameter.Begin to tighten tapered gland nut 2 this moment, the conical surface of tapered gland nut 2 progressively compresses the conical surface of tapered interior ring cutting ferrule 4 along with the axial feed of tapered gland nut 2 screw threads, ring cutting ferrule 4 tightens up the circle that state annular barb structure forms a sealing in tapered, and hangnail structure and nylon tube are transition fit when tightening up state; In the process that tapered gland nut 2 screw threads are tightened, ring cutting ferrule 4 hangnail rings tightly are stuck in nylon tube 1 between cutting ferrule 4 and the guide sleeve 5 in tapered, nylon tube 1 can not be come out from pull-off in the joint, ring cutting ferrule 4 also compresses special-shaped rubber seal 6 in simultaneously tapered, realizes sealing between nylon tube 1, guide sleeve 5 and valve port 7.Ring cutting ferrule 4 cutting ferrule outsides have the thick tapering that cooperates with swivel nut in thin bottom, top in tapered.Valve port 7 processes screw thread, O type rubber seal ring recess and the special-shaped rubber seal ring recess of energy and tapered gland nut 2 couplings.After tapered gland nut 2 was tightened, the screw thread place of 3 pairs of valve ports 7 of O type rubber seal and tapered gland nut 2 realized envelope dirt and sealing.Like this, nylon tube and working body have just been realized being tightly connected fully.
