Description
Technical field
The utility model relates to valve class connection set in a kind of automobile brake pipeline.
Background technique
Each valve class such as one-way valve, quick release valve, air brake valve, unloading valve etc. in the automobile brake pipeline needed pre-joint in the past when these products of assembling.Need be coated with thread locking adhesive in the pre-joint process, add gasket seal; Be connected with the pressure tube of threaded joint then, connection procedure need be coated with sealer, tightens after the rotation multi-turn.But in this process, easily produces gas leakage because of pre-joint or online assembling are defective, necessary replacing this moment causes the rhythm of production disorder even stops the serious consequence of line, assembles loaded down with trivial detailsly, and it is low once to assemble up-to-standard rate, and manufacturing efficiency is low; In being coated with the thread locking adhesive process, the sealer consumption is difficult to accurate control in addition, causes the sealer consumption too much to flow into easily and produces quality problems in the valve body, and there is hidden danger in quality of product.
The model utility content
The purpose of this utility model is to provide valve class quick access device in the automobile brake pipeline, and it is loaded down with trivial details effectively to solve existing valve class assembly process, and manufacturing efficiency is low, and the sealer consumption too much is easy to generate the problem of quality.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: valve class quick access device in the automobile brake pipeline, it is characterized in that: comprise the packing ring, snap ring and the nut seat that are located at successively in the valve body interface, be threaded between nut seat and the valve body interface, be provided with seal ring between nut seat and the valve body interface end.
Further, the valve body interface is provided with chamber A, chamber B and thread cavity C successively, chamber A end face, chamber B inner headed face are corresponding with packing ring, chamber B end face, the smooth inner headed face of thread cavity C are corresponding with snap ring, the internal thread of thread cavity C connects with the outside thread of nut seat is corresponding, valve body interface end is provided with sealing surface, and thread cavity C end is provided with chamfering I, is provided with chamfering II between thread cavity C and the chamber B.
Further, the internal thread specification is M22 * 1.5-6H, M16 * 1.5-6H or M10 * 1.5-6H among the thread cavity C.
Further, the axial inclination alpha of sealing surface and valve body interface is 8 °.
Further, the outer end diameter of inclination alpha thread cavity C internal thread specification when being M22 * 1.5-6H, M16 * 1.5-6H, M10 * 1.5-6H corresponding respectively value be Φ 23
0 + 0.1Mm, Φ 17
0 + 0.1Mm, Φ 11
0 + 0.1Mm.
Further, the depth dimensions of valve body interface (1): sealing surface (6) degree of depth 2.5
-0.05 + 0.1Mm, thread bottom are to end face 12mm, the thread cavity C degree of depth 16 ± 0.15mm, the chamber B degree of depth 23 ± 0.15mm.
Further, chamfering I is 45 ° and extends to height of thread.
Further, chamfering II is 0.5mm * 45 °.
Further, packing ring adopts rubber to make.
Further, seal ring adopts the RUBBER O RunddichtringO.
The utility model is owing to adopted technique scheme, reduced loaded down with trivial details assembly process, saved the operation of pre-joint, save installation time greatly, improve and once assemble up-to-standard rate, and solved sealer and too much flowed into the hidden danger that produces quality problems in the valve body, only the simple insertion of exterior tube plug can need have been formed reliable sealing.
