Abstract
The utility model relates to a valve core of a U-shaped groove milled with a plane, which is characterized in that small planes (1.1) are arranged on the two sides of the valve core (1) and the U-shaped groove (1.2) respectively. The valve core of the U-shaped groove milled with a plane can realize the quick assembly without damaging the O-shaped seal ring and has the advantage of reducing manufacturing cost as well.
Description
(1) technical field
The utility model relates to a kind of spool.Be mainly used in the assembling of spool and valve body in the hydraulic system.The valve kind technical field.
(2) background technique
The spool in the hydraulic system and the sealing of valve body realize by " O " RunddichtringO.When assembling " O " RunddichtringO through the U type groove end of the spool one end spool of packing into.Before the utility model was made, there was sharp edge the U type groove both sides of present spool.Pack into when using from U type groove end when " O " RunddichtringO, can scratch " O " RunddichtringO because U type groove both sides have sharp edge to exist.Thereby the working life of influence " O " RunddichtringO, or because poorly sealed and cause leakage, thus the increase of cost caused.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and do not damage the U type groove of " O " RunddichtringO to be milled with the spool on plane.
The purpose of this utility model is achieved in that a kind of U type groove is milled with the spool on plane, is respectively to process a facet in the both sides of the U of described spool type groove.
The utility model replaces the sharp edge of traditional U type groove both sides with facet, like this when " O " RunddichtringO when U groove end is packed into, will be that face contacts between U type groove and " O " RunddichtringO, so just can not scratch " O " RunddichtringO.Thereby overcome the shortcoming that original line contact makes the wearing and tearing of " O " RunddichtringO easily.
(4) description of drawings
Fig. 1 is milled with the Facad structure schematic representation of the spool on plane for the utility model U type groove.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the A-A cut-away view of Fig. 2.
Among the figure: spool 1, facet 1.1, U type groove 1.2, a represent that height, the b of the relative valve core axis of facet represent that institute's milling flat represents faceted axial length at circular arc, the c of U type groove root.
(4) embodiment
Referring to Fig. 1～3, the U type groove that the utility model relates to is milled with the spool on plane, is respectively to mill out a facet 1.1 as shown in Figure 1 in the both sides of the U of spool 1 type groove 1.2.
Claims (1)
1, a kind of U type groove is milled with the spool on plane, it is characterized in that: be respectively to process a facet (1.1) in the both sides of the U type groove (1.2) of described spool (1).
