Abstract

The invention discloses a special integrated group valve for an electrohydraulic push rod. The special integrated group valve for the electrohydraulic push rod comprises a valve body (1), load control valves (2), an oil-guide screw plug (3), a pilot-operated check valve (4), a non-return valve (5) and overflow valves (6). The load control valves (2), the oil-guide screw plug (3) and the overflow valves (6) are respectively mounted in threaded holes on the upper end face of the valve body (1), and the pilot-operated check valve (4) and the non-return valve (5) are respectively mounted in threaded holes on a side face of the valve body (1). The special integrated group valve for the electrohydraulic push rod disclosed by the invention has stable load, no hydraulic shock can be generated, and no damage to equipment can be caused.

Description

The special-purpose integrated valve group of Electrohydraulic push rod
Technical field
The present invention relates to the special-purpose integrated valve group of a kind of Electrohydraulic push rod.
Background technique
Electrohydraulic push rod is a kind of collection machine, electricity, and liquid is the hydraulic driving mechanical of one, being applicable to needs the reciprocating sliding straight line motion maybe to need to rise, the occasion of decline work, and can realize concentrating and control automatically of remote dangerous area.Electrohydraulic push rod is by oil cylinder, and valve group and power source are formed, and wherein the valve group is the core position of Electrohydraulic push rod, and the valve group that present most Electrohydraulic push rod uses comprises relief valve, one-way valve, Pilot operated check valve.Owing to do not have speed governing or load balance valve, often because the too fast oil pump flow that causes of load rate of descent is not enough, makes the load shakiness and produce hydraulic shock when the small flow low-pressure uses, equipment is worked the mischief.
Summary of the invention
The purpose of this invention is to provide the special-purpose integrated valve group of a kind of Electrohydraulic push rod.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: the special-purpose integrated valve group of a kind of Electrohydraulic push rod; Comprise valve body (1), load control valve (2), Oil Guide plug screw (3), Pilot operated check valve (4), one-way valve (5) and relief valve (6); Said load control valve (2), Oil Guide plug screw (3) and relief valve (6) are installed in respectively in the tapped hole of valve body (1) upper-end surface, and said Pilot operated check valve (4) and one-way valve (5) are installed in respectively in the tapped hole of valve body (1) side.
(2) at least two of said load control valves.
(6) at least two of said relief valves.
The special-purpose integrated valve group of a kind of Electrohydraulic push rod of the present invention, load is stable, can not produce hydraulic shock, can not work the mischief to equipment.
Description of drawings
Fig. 1 is the structural drawing of the special-purpose integrated valve group of a kind of Electrohydraulic push rod of the present invention.
Fig. 2 is the fundamental diagram of the special-purpose integrated valve group of a kind of Electrohydraulic push rod of the present invention.
Fig. 3 is the fundamental diagram of the special-purpose integrated valve group of a kind of Electrohydraulic push rod of the present invention.
Among the figure: 1, valve body; 2, load control valve; 3, Oil Guide plug screw; 4, Pilot operated check valve; 5, one-way valve; 6, relief valve.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, the special-purpose integrated valve group of Electrohydraulic push rod comprises valve body 1, load control valve 2, Oil Guide plug screw 3, Pilot operated check valve 4, one-way valve 5 and relief valve 6; Load control valve 2, Oil Guide plug screw 3 and relief valve 6 are installed in respectively in the tapped hole of valve body 1 upper-end surface; Pilot operated check valve 4 is installed in respectively in the tapped hole of valve body 1 side with one-way valve 5, when piston rod stretches out, like Fig. 3; Come the fluid of self-pumping to open one-way valve and one-way throttle valve entering rodless cavity; Rod chamber fluid flows back to fuel tank through throttle valve also Pilot operated check valve, and inversion principle is identical, can regulate the oil cylinder motion speed through throttle valve; Like Fig. 2, the installation load control valve can prevent that loading speed from changing suddenly.

Claims (3)

1. the special-purpose integrated valve group of an Electrohydraulic push rod; It is characterized in that: comprise valve body (1), load control valve (2), Oil Guide plug screw (3), Pilot operated check valve (4), one-way valve (5) and relief valve (6); Said load control valve (2), Oil Guide plug screw (3) and relief valve (6) are installed in respectively in the tapped hole of valve body (1) upper-end surface, and said Pilot operated check valve (4) and one-way valve (5) are installed in respectively in the tapped hole of valve body (1) side.
2. the special-purpose integrated valve group of a kind of Electrohydraulic push rod according to claim 1 is characterized in that: (2) two of said load control valves at least.
