The oil pressure soft bypass valve has the beneficial effects of solving problems of vibration and turbulence, as well as achieving dual effects of a safety valve and an adjusting valve.
Description
Technical field
The present invention relates to F16K17/00 safety valve, equilibrium valve classification on the International Classification of Patents (IPC) through retrieval, especially belongs to the soft bypass valve of a kind of oil pressure.
Background technique
Traditional valve does not generally have piston, spring compression be sealing cover, be to lean on the up-down of spool to open and close bypass, fluid directly impacts spool like this, can produce vibrations and turbulent, makes unstable working condition, and causes the damage of device easily.
Summary of the invention
The object of the present invention is to provide the soft bypass valve of a kind of oil pressure, solved the problem of vibrations and turbulent flow, play the double effects of safety valve and modulating valve.
The technological scheme that the present invention taked is: it comprises end cap (1), bolt of cover (9) and has fluid inlet (71) and the valve body (7) of fluid output (72); It is characterized in that: be shaped on valve body chamber (73) in the described valve body (7); Valve body chamber (73) is connected with fluid output (72) with fluid inlet (71), and valve body chamber (73) also are slidingly connected with piston (8); Described piston (8) is made up of dividing plate (81), piston top (82) and piston bottom (83); Described piston top (82) is connected with spring capping (3) through spring (5), and spring capping (3) is connected with valve body chamber (73) with screw rod (6), and screw rod (6) is connected with end cap (1); Be shaped on piston hole (84) on the described piston bottom (83).
Beneficial effect of the present invention is: because the mode that the present invention adopts piston (8) in valve body (7), to move to regulate automatically the pressure release flow; The porous throttling of being adopted; Changed the flow direction; Enlarge fluid displacement, fundamentally solved when fluid flows and shaken and turbulent problem, played the double effects of safety valve and modulating valve.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is principle of the invention figure; As shown in the figure; It comprises end cap (1), bolt of cover (9) and has fluid inlet (71) and the valve body (7) of fluid output (72); It is characterized in that: be shaped on valve body chamber (73) in the described valve body (7), valve body chamber (73) are connected with fluid output (72) with fluid inlet (71), and valve body chamber (73) also are slidingly connected with piston (8); Described piston (8) is made up of dividing plate (81), piston top (82) and piston bottom (83); Described piston top (82) is connected with spring capping (3) through spring (5), and spring capping (3) is connected with valve body chamber (73) with screw rod (6), and screw rod (6) is connected with end cap (1); Be shaped on piston hole (84) on the described piston bottom (83).
Spring capping described in the present invention (3) is to adopt elastic cylindrical pin (4) to be positioned in the valve body chamber (73).
Screw rod described in the present invention (6) is to adopt nut (10) and nut (11) to fix.
Working principle of the present invention is: fluid is flowed in the valve body (7) by fluid inlet (71) during work, and along with fluid inlet (71) is located the increase of hydrodynamic pressure, it is mobile valve body (7) in to promote piston (8).After the pressure of fluid is greater than the pressure of spring (5), will promote piston (8) and move upward, piston hole (84), fluid output (72) that fluid is passed through on the piston (8) flow out, and reach the effect of pressure release.
Because the pressure release flow moved along with piston (8) and slowly increases when piston (8) moved valve body (7) in, so can not occur the impact of unlatching suddenly during pressure release.
When needs change the fluid pressure difference that fluid inlet (71) and fluid output (72) locate; Can pass through the position of rotary screw (6) Regulation spring gland (3) on screw rod (6); Can change the elastic force of spring (5), and reach the purpose that regulated fluid import (71) and fluid output (72) are located fluid pressure difference.
In addition; The present invention is because the pressure release mode is through slowly pressure release of the piston hole (84) on the piston (8); Therefore; It is also just big more to the pressure of spring (5) that the hydrodynamic pressure of fluid inlet (71) is got over big piston (8), and the area that piston hole (84) on the piston (8) and fluid output (72) communicate will be big more, and the pressure release ability is just strong more.
