Abstract
The utility model relates to a take technique of the valve of the gliding closed component of straight line, this kind of valve include the valve body, establish the by pass hole on the valve body, adorn valve barrel and case in the valve body, fix the spring on valve barrel, case, and the sealing surface of valve barrel case all is the inclined plane. The bypass valve is easy to close and well sealed.
Description
The utility model belongs to the technical field of the valve of the closure member of being with linear slide.
The bypass valve of using on the present helicoid hydraulic motor, comprise the valve body which is provided with by-pass prot, be contained in the valve pocket in the valve body, be contained in the spool in the valve body, because of the sealing surface of valve pocket and spool all is the plane, along with flowing of liquid in the valve, spool is closed by-pass prot automatically, along with reducing of passage, and it is still big like that by the flow of by-pass prot, so just cause sometimes will the pass not deadly, make it high pressure liquid stream erosion spool, bad the bypass valve erosion.
The purpose of this utility model provides a kind ofly closes easily the valve of good airproof performance.
This bypass valve comprises valve body, is located at the by-pass prot on the valve body, is contained in the valve pocket in the valve body, is contained in the spool in the valve body, is fixed on the spring on valve pocket and the spool, and the sealing surface of valve pocket takes the form of inclined plane, and the sealing surface of spool also takes the form of inclined plane.
Because the sealing surface of valve pocket and spool all takes the form of inclined plane, therefore close easily, and good airproof performance.
Accompanying drawing shows embodiment of the present utility model
Bypass valve as shown in Figure 1, comprise that one section is garden cylindricality, one section valve body (1) that is garden platform shape, be located at the by-pass prot (2) on the valve body (1), be contained in the valve pocket (6) that the sealing surface (11) of the interior right-hand member of valve body (1) takes the form of inclined plane, be contained in the U-shaped sealing ring (9) between valve body (1) and valve pocket (6), be contained in the spool (7) that the sealing surface (12) in the valve body (1) takes the form of inclined plane, be fixed on the spring (8) on valve pocket (6) and the spool (7), be contained in the O-ring seals (10) between valve body (1) and spool (7).By-pass prot (2) comprises the hole (3) that is located on the valve body (1), is screwed in the plug (5) on the hole (3), is fixed on sieve plate (4) on the hole (3) with plug (5).
Claims (3)
1, a kind of bypass valve, comprise valve body (1), be located at the by-pass prot (2) on the valve body (1), be contained in the valve pocket (6) in the valve body (1), be contained in the spool (7) in the valve body (1), be fixed on valve pocket (6) and spool (7) upper spring (8), it is characterized in that the sealing surface (11) of valve pocket (6) takes the form of inclined plane, the sealing surface (12) of spool (7) also takes the form of inclined plane.
