Abstract
The utility model relates to a shunting and pressure reducing valve, comprising a spool valve, wherein an oil drainage port, a pressure inlet and a pressure reducing outlet are orderly arranged at one side of the spool valve from the top to the bottom; and another section of the spool valve is added with a shunting outlet. The utility model has the advantages that a flexible shunting oil outlet is arranged on the spool valve so that the residual pressure oil is led out through the shunting outlet and used by an oil motor and that the residual hydraulic pressure can be inversely transferred to the motor while the pressure reducing pressure is maintained in priority, thereby saving energy.
Description
Technical field
The utility model relates to the hydraulics field, relates in particular to a kind of shunting decompression valve that both can reduce pressure and can shunt.
Background technique
Reduction valve is the outlet pressure that inlet pressure is reduced to a certain needs through regulating; And the energy that relies on medium itself makes outlet pressure keep stable valve automatically; Be a throttle element that local resistance can change,, the kinetic energy of flow velocity and fluid changed promptly through changing orifice size; Cause the different pressure losses, thereby reach the purpose of decompression.Reduction valve also is to use very wide a kind of pressure valve in the hydraulic equipment, but in oil hydraulic circuit, need when keep pressure-reduction outlet pressure, use and unnecessary pressure oil liquid is introduced other loop, and be not to fall with the relief valve overflow, therefore can waste a lot of energy.
Summary of the invention
To above defective, the utility model provides a kind of pressure-reducing function that both had, and the shunting decompression valve that has shunting action again is to solve many deficiencies of existing technology.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of shunting decompression valve comprises spool, and a said spool wherein side is offered drain tap, pressure inlets and relief outlet from top to bottom successively, and said spool is set up a shunting outlet for other one section.
The beneficial effect of the described shunting decompression valve of the utility model is: distribute hydraulic fluid port flexibly through on spool, setting up one; Make its can preferentially keep the decompression pressure in; Use and unnecessary pressure oil drawn with oil motor through this split-flow opening; Simultaneously with unnecessary hydraulic pressure again anti-pass give motor, thereby saved the energy.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the said shunting decompression valve of the utility model embodiment.
Among the figure:
1, spool; 2, drain tap; 3, pressure inlets; 4, relief outlet; 5, shunting outlet.
Embodiment
As shown in Figure 1, the described shunting decompression valve of the utility model embodiment comprises spool 1, and said spool 1 a wherein side is offered drain tap 2, pressure inlets 3 and relief outlet 4 from top to bottom successively, said spool 1 other one section set up a shunting outlet 5.Through on one section of valve body increase and valve body, having opened a hydraulic fluid port in correspondence more; When 4 standard-sized sheet time-division of relief outlet outflow opening 5 contract fully just; When relief outlet 4 is progressively closed; Shunt outlet 5 just corresponding opening, when relief outlet 4 maintained a suitable opening, shunting outlet 5 is mouth of just corresponding unlatching also like this; When relief outlet 4 strengthens, shunt outlet 5 corresponding reducing, relief outlet 4 reduces, shunting outlet 5 corresponding increases.Like this, reduction valve is being kept delivery pressure when constant, automatically according to outside need fluid what and spool 1 is maintained some positions; Shunting outlet 5 can be derived unnecessary pressure oil, when the outside is very big with oil mass, and relief outlet 4 standard-sized sheets; Shunting outlet 5 is closed, not shunting; Need not when oil when the outside, relief outlet 4 is close to close keeps decompression pressure, and shunting outlet 5 standard-sized sheets are all drawn pressure oil.
Claims (1)
1. a shunting decompression valve comprises spool, and a said spool wherein side is offered drain tap, pressure inlets and relief outlet from top to bottom successively, it is characterized in that: said spool is set up a shunting outlet for other one section.
