Abstract

The invention relates to a multiple directional control valve. The multiple directional control valve comprises an oil inlet valve component, an oil outlet valve component, and at least one cylinder valve body component mounted between the oil inlet valve component and the oil outlet valve component, wherein an executing mechanism is connected with the cylinder valve body component; the cylinder valve body component comprises a valve body, a valve rod, a reset spring mounted at the end of the valve rod, and an oil way and an oil outlet way which are communicated with the valve rod; the upper end of the oil way is connected with a one-way valve; the oil way is bent in an arc-shaped way to form a convex shape. The multiple directional control valve has the benefits that the size is small, higher internal pressure can be born, the flow in the oil way is large, the transmission power is great, and the transmission effect on the executing mechanism is good.

Description

Multiple directional control valve

Technical field

The present invention relates to a kind of multiple directional control valve.

Background technique

Multiple directional control valve is the control system on hydraulic pressure, controls the flow direction of hydraulic oil, is the critical component of hydraulic system.Conventional selector valve volume is large, and the flow of internal hydraulic pressure oil is little, and oil duct is curved, and interior pressure is little, easily leakage of oil, and stability is not high.

Summary of the invention

The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of multiple directional control valve.

The present invention solves the technological scheme that its technical problem adopts: a kind of multiple directional control valve, comprise oiling valve parts, outlet valve parts and be installed on oiling valve parts and at least one oil cylinder valve body component of outlet valve parts centre, actuator is connected with oil cylinder valve body component, oil duct, oil discharge passage that oil cylinder valve body component comprises valve body, valve rod, is installed on the Returnning spring of valve rod end and is connected with valve rod, the upper end of oil duct is connected with one-way valve, and oil duct is " protruding " font of circular arc bending.

Further, oil duct from top to bottom the radius of arc section be respectively: R8, R10 and R6.

Further, the internal diameter of oil duct is 100mm.

Further, valve rod outer end is connected with handle, and the handle outside being connected with valve rod is connected with dust-proof cover, and the material of dust-proof cover is nitrile rubber.

Further, the overload valve being connected with oil discharge passage is installed on valve body.

The invention has the beneficial effects as follows: volume is little, can bear larger interior pressure, in oil duct, flow is large, and transferring power is large, effective to the transmission of actuator.

Brief description of the drawings

Below in conjunction with accompanying drawing, the present invention is further described.

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structural representation of oil cylinder valve body component.

Wherein: 1. oiling valve parts, 2. outlet valve parts, 3. oil cylinder valve body component, 4. valve body, 5. valve rod, 6. Returnning spring, 7. oil duct, 8. one-way valve, 9. dust-proof cover, 10. overload valve.

Embodiment

The invention will be further described in conjunction with specific embodiments now, and following examples are intended to illustrate the present invention instead of limitation of the invention further.

A kind of multiple directional control valve as shown in Figure 1 and Figure 2, comprise oiling valve parts 1, outlet valve parts 2 and be installed on oiling valve parts 1 and at least one oil cylinder valve body component 3 of outlet valve parts 2 centres, actuator is connected with oil cylinder valve body component 3, oil duct 7, oil discharge passage that oil cylinder valve body component 3 comprises valve body 4, valve rod 5, is installed on the Returnning spring 6 of valve rod 5 ends and is connected with valve rod 5, the upper end of oil duct 7 is connected with one-way valve 8, and oil duct 7 is " protruding " font of circular arc bending." protruding " font oil duct 7 makes the flow of oil duct 7 interior transformer oils larger, transmission better effects if, and be convenient to cast the oil cylinder valve body component 3 of more volume, to the transmission better effects if of actuator.

The oil duct 7 from top to bottom radius of arc section is respectively: R8, R10 and R6, and the internal diameter of oil duct 7 is 100mm, now the flow in oil duct 7 reaches 80L/min, when maximum, can reach 100L/min.

Valve rod 5 outer ends are connected with handle, and the handle outside being connected with valve rod 5 is connected with dust-proof cover 9, and the material of dust-proof cover 9 is nitrile rubber.Dust-proof cover good dustproof effect, easy to use.

The overload valve 10 being connected with oil discharge passage is installed on valve body 4, in the time that the pressure in oil discharge passage is excessive, can carrys out pressure release by overload valve 10, prevent valve body 4 compressive deformations.

Multiple directional control valve good pressure-resistant performance, the interior pressure that can bear 30MPa, in oil duct, flow is large, and transferring power is large, effective to the transmission of actuator.

Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
