Abstract
The utility model belongs to the technical field of automobile pipelines, in particular to a pipeline sealing structure, which includes a valve body, an O-shaped rubber sealing ring and a pipe joint. The pipeline sealing structure is characterized in that a plane of the pipe joint, which needs to be sealed, is provided with a rubber sealing ring embedded groove matched with the O-shaped rubber sealing ring in size; the section of the rubber sealing ring embedded groove is a trapezium with a large opening and a small bottom; the valve body and the pipe joint are fixedly connected through screw threads; and the diameter of the O-shaped rubber sealing ring is larger than the depth of the embedded groove. The pipeline sealing structure has good sealing effect and lower cost, and is suitable for the end surface sealing design of braking pipelines, steering pipelines and clutch pipelines.
Description
Technical field
The utility model belongs to automobile pipeline technical field, particularly a kind of line seal structure, and it relates to braking line, turns to pipeline, the end face seal of clutch pipeline design.
Background technique
In the automobile chassis design, line seal is even more important.He relates to the Security and the reliability of automobile.If can vehicle performance be guaranteed from designing the reliability that improves line seal.
Traditional line seal design generally has dual mode, is respectively:
1. copper packing sealing, it directly adds copper washer on the face that needs to seal on the adapter head, be screwed into valve body and get final product.Its advantage is simple in structure, and is easy for installation, and shortcoming is that sealing effect is poor, and the end face oil leakage phenomenon often takes place; Another is that the copper packing cost is higher relatively; Also have in store management, copper packing is lost easily, brings unnecessary trouble to production management.
2. the cone ring adds " O shape " rubber ring seal, and cover upper cone ring adds seal with elastometic washer on the adapter head.With respect to first kind of seal form, this sealing structure effect is much improved, and shortcoming is a complex structure, and cone ring manufacture cost is higher relatively.
Summary of the invention
The purpose of this utility model is: a kind of line seal structure is provided, and its good sealing effect, cost is lower.
The technical solution of the utility model is: design a kind of line seal structure, it comprises valve body, " O shape " rubber seal and takes over head, it is characterized in that: take over a plane that head needs seal have one with the supporting rubber seal embedded groove of " O shape " rubber seal size, the cross section of rubber seal embedded groove is a mouthful big end little " trapezoidal ", and valve body is fixedlyed connected by screw thread with the adapter head; The diameter of " O shape " rubber seal is greater than the embedded groove degree of depth.
The diameter of described " O shape " rubber seal is greater than embedded groove degree of depth 1mm-2mm.
Characteristics of the present utility model are: according to the screw thread specification, select suitable " O shape " rubber seal, because this line seal structure, it be processed with on a plane of taking over head and need sealing one with the supporting rubber seal embedded groove of " O shape " rubber seal size, the cross section of rubber seal embedded groove is a mouthful big end little " trapezoidal ", when valve body spins with the adapter head thread, make sealing effect reach desirable requirement by mutual extrusion, thereby play good sealing effect.This form good sealing effect, easy for installation, saved cone ring or copper washer, reduced cost, reliability is also guaranteed simultaneously.
Description of drawings
Below in conjunction with embodiment the utility model is described further.
Fig. 1 is known copper packing sealed structural representation.
Fig. 2 is that known cone ring adds " O shape " rubber ring seal structural representation.
Fig. 3 the utility model embodiment line seal structural representation.
Fig. 4 is the schematic cross-section of Fig. 3 rubber seal embedded groove.
Among the figure: 1, valve body; 2, copper washer; 3, take over head; 4, " O shape " rubber seal; 5, centrum ring; 6, embedded groove.
Specific embodiment
As shown in Figure 1, this is known copper packing sealing configuration, and it directly adds copper washer 2 taking on the face that needs to seal on 3, is screwed into valve body 1 and gets final product.Its advantage is simple in structure, and is easy for installation, and shortcoming is that sealing effect is poor, and the end face oil leakage phenomenon often takes place; Another is that the copper packing cost is higher relatively; Also have in store management, copper packing is lost easily, brings unnecessary trouble to production management.
As shown in Figure 2, this is that known cone ring adds " O shape " rubber ring seal, and cover upper cone ring 5 adds 4 sealings of " O shape " rubber washer on 3 taking over, and will take over 3 then and fixedly connected with valve body 1.With respect to first kind of seal form, this sealing structure effect is much improved, and shortcoming is a complex structure, and cone ring 5 manufacture costs are higher relatively.
The utility model embodiment such as Fig. 3, shown in Figure 4, this line seal structure, it comprises valve body 1, " O shape " rubber seal 4 and take over 3, it take over 3 need the planes of sealing be processed with one with the supporting rubber seal embedded groove 6 of " O shape " rubber seal 4 sizes, the cross section of rubber seal embedded groove 6 is mouthful big ends little " trapezoidal ", " O shape " rubber seal 4 is placed in the rubber seal embedded groove 6 during use, when valve body 1 spins with adapter 3 screw thread, the diameter of " O shape " rubber seal 4 is greater than embedded groove 6 degree of depth, make " O shape " rubber seal 4 fully stressed by mutual extrusion, " O shape " rubber seal 4 can be filled up valve body 1 and be taken over a space of 3, makes sealing effect better.
It is easy for installation that the cross section of this rubber seal embedded groove 6 is mouthful that other shaped cross embedded groove is compared at a big end little " trapezoidal ", and better sealing effect is arranged.And saved cone ring or copper washer, and having reduced cost, reliability is also guaranteed simultaneously.
Particularly the diameter of " O shape " rubber seal is greater than embedded groove degree of depth 1mm-2mm, and the sealing effect of " O shape " rubber seal is the most desirable at this moment.
Claims (2)
1. line seal structure, it comprises valve body, " O shape " rubber seal and takes over head, it is characterized in that: take over a plane that head needs seal have one with the supporting rubber seal embedded groove of " O shape " rubber seal size, the cross section of rubber seal embedded groove is a mouthful big end little " trapezoidal ", and valve body is fixedlyed connected by screw thread with the adapter head; The diameter of " O shape " rubber seal is greater than the embedded groove degree of depth.
2. according to the line seal structure described in the claim 1, it is characterized in that: the diameter of described " O shape " rubber seal is greater than embedded groove degree of depth 1mm-2mm.
