Abstract

The utility model aims to provide a one-way static seal Y-shaped rubber sealing ring for a hydraulic cylinder bracket, which is applied to novel one-way static seal rubber sealing ring structures of sealing pieces for hydraulic cylinder brackets in engineering machinery, coal machinery and the like. The phenomenon of liquid leakage on the upper cavity of a jack for the hydraulic bracket and the outer side of a guide sleeve can be eliminated, the pressure retaining property index can be raised by 90 percent, and the product processing period can be reduced by 80 percent. The aims of the utility model are fulfilled as follows: the one-way static seal Y-shaped rubber sealing ring comprises an outer lip and an inner lip, wherein the section structure of the sealing ring is Y-shaped; on the outer side of the Y-shaped ring, an auxiliary lip is formed between the bottom and the outer lip; the auxiliary lip has a triangular convex structure; the outer lip is thick and short, and is sealed tightly; and the inner lip is slender, and has certain interference amount, so that tight fit between the inner lip and the bottom of the groove is ensured. The one-way static seal Y-shaped rubber sealing ring is used for replacing an O-shaped ring-retainer ring structure of a sealing piece one-way static seal sealing gum sealing ring for the conventional hydraulic cylinder bracket.

Description

Hydraulic cylinder leg is with unidirectional static seal Y type rubber seal
One, technical field
The utility model relates to a kind of hydraulic cylinder leg with unidirectional static seal Y type rubber seal, and it is mainly used in the sealing of hydraulic cylinder legs such as engineering machinery, coal mine machinery.
Two, background technique
Existing conventional hydraulic jar support generally adopts an O type circle to add the form of a back-up ring, though simple in structure with the unidirectional static seal glue of Sealing ring structure; Easily manufactured. but because structural inadequate natural endowment; Product strength is low, wears no resistance poor impact resistance; Working life is short; Have a strong impact on the unidirectional static seal effect between hydraulic cylinder leg guide sleeve and the oil hydraulic cylinder, reliability, poor stability, the maintain and replace frequency is many. have a strong impact on manufacturing efficiency and safety in production such as engineering machinery, coal mine machinery.
Three, the content of model utility
The purpose of the utility model provides a kind of hydraulic cylinder leg with unidirectional static seal Y type rubber seal; Be used for hydraulic cylinder legs such as engineering machinery, coal mine machinery with the unidirectional static seal rubber seal of Sealing new structure; It can be eliminated the hydraulic support jack epicoele and the guide sleeve outside phenomenon of leakage; Pressurize property index can improve 90 percent, and the product process-cycle can dwindle 80 percent.
The purpose of the utility model realizes like this: it comprises outer lip, epipharynx, and its cross-sectional configuration of seal ring is the Y type; In the Y-shaped ring outside, a secondary lip is arranged between bottom and the outer lip, the structure of secondary lip is the triangular hill shape; The outer lip tubbiness, epipharynx is elongated and certain magnitude of interference arranged.
The utility model is to adopt the polyurethane material with high abrasion and high-intensity performance, and it is widely used in the oil hydraulic cylinders such as engineering machinery, mining machinery.The alternative conventional hydraulic jar support of the utility model adds the back-up ring structure with the O type circle of the unidirectional static seal glue of Sealing seal ring.
The utility model adopts high abrasion.The high-strength polyurethane material utilizes high-accuracy CNC CNC processing technology, the time processing moulding.
Four, description of drawings:
Accompanying drawing 1 is the structural drawing of the utility model.
Accompanying drawing 2 is the cross-section structure of accompanying drawing 1.
Wherein: the secondary lip of 1---, 2---outer lip, 3---epipharynx.
Five, embodiment
Describe in further detail combining accompanying drawing and embodiment to come the utility model done down.
With reference to accompanying drawing, the utility model hydraulic cylinder leg is with unidirectional static seal Y type rubber seal, and it comprises outer lip 2; Epipharynx 3, its cross-sectional configuration of seal ring is the Y type, in the Y-shaped ring outside; Between bottom and the outer lip 2 a secondary lip 1 arranged, the structure of secondary lip 1 is the triangular hill shape, outer lip 2 tubbiness; Seal powerfully, epipharynx 3 is elongated and certain magnitude of interference is arranged, and guarantees and the fitting tightly of channel bottom.
