Description

Plug-in type oil circuit integrated package

Technical field

The utility model relates to a kind of hydraulic manifold block, belongs to technical field of hydraulic.

Background technique:

Some hydraulic element that often use in the automatic industrial system, as Pilot operated check valve, overflow control reversible lock, relief valve, series flow control valve etc., they all are board-like usually or are threaded in the hydraulic system, it is bigger all to show monomer size, installs inconvenient.Make hydraulic system restricted in bulk.The hydraulic manifold block that ZL200420024928.5 provides, its internal structure do not have arrangements for speed regulation and pressure test part, and loading and unloading are inconvenient.

Summary of the invention

The purpose of this utility model provides a kind of two-way fuel feeding, bidirectional speed governing, easy to loading and unloading, the internal structure compactness, cost is low, and is easy to use, the plug-in type oil circuit integrated package that auto-lock function is good.

The purpose of this utility model is achieved in that plug-in type oil circuit integrated package, comprise valve body and two groups of Pilot operated check valves, two groups of relief valves are installed on valve body by integrated two asphalt channels of oil circuit, it is characterized in that being provided with series flow control valve and pressure test mouth, series flow control valve is located on the oil circuit of asphalt channel, the pressure test mouth is arranged between two asphalt channels, article two, the asphalt channel import connects oil pump, and outlet connects oil cylinder, and Pilot operated check valve is arranged on the asphalt channel outlet port.

Described Pilot operated check valve is that formations such as valve seat, valve port and ball valve seat, spring, ball valve, spool are installed on valve body, and ball valve places in the middle of spool and ball valve seat, the spring.

Described relief valve is relief valve seat, voltage regulation screw, spring, ball valve, ball valve seat, jam nut to be installed constitute on valve body, is connected on the working connection of one-way valve bottom of asphalt channel.

The utility model is rational in infrastructure simple, manufactures easily, and cost is low.With two groups of Pilot operated check valves, two groups of relief valves, two groups of series flow control valves concentrate in together, the internal structure compactness, volume is little, is convenient to loading and unloading.Be applied to make unit simple in structure in the hydraulic push rod device.Be provided with speed governing, relief valve, can regulate the speed freely, pressure.Be provided with Pilot operated check valve in the oil circuit, when system quit work, control oil channel pressure descended, and Pilot operated check valve is closed simultaneously, makes the rapid stop motion of inner body, plays self-locking action.At return opening series flow control valve being set can regulate the speed speed.Between two asphalt channels (hyperbaric chamber), be provided with a guiding valve, make the pressure test mouth be communicated with a shared oil pocket,, can test system pressure at pressure test mouth setting pressure table.This plug-in type oil circuit integrated package can be widely used in hydraulic machinery equipment such as hydraulic push rod, improves the usability of equipment, prolongs the working life of equipment.

Embodiment

Valve body 1 is made of two-part up and down, is connected and fixed by set screw.Two groups of Pilot operated check valves 24 that are made of valve seat 8, valve port 4 and ball valve seat 6, spring 7, ball valve 5, spool 3 respectively are installed on valve body 1, and ball valve 5 places in the middle of spool 3 and ball valve seat 6, the spring 7.Two groups of relief valves 23 that are made of relief valve seat 13, ball valve body 14, voltage regulation screw 18, spring 15, ball valve 2, ball valve seat 16, jam nut 17 respectively are installed in the bottom of valve body 1.Two groups of Pilot operated check valves 24 and two groups of relief valves 23 are installed on the valve body 1, and by oil circuit integrated oil path passage X-X1 and asphalt channel Y-Y1.Article two, the X of asphalt channel end and Y end are the asphalt channel import, connect oil pump; X1 end and Y1 end connect oil cylinder for the asphalt channel outlet, and Pilot operated check valve is arranged on the asphalt channel outlet port, and asphalt channel inlet is provided with the scavenger valve 10 of commutation stage clip 9.Be located on the oil circuit of asphalt channel at the series flow control valve 25 that speed governing screw 20 and nut 21 formations are installed on the

valve body

1,26,27 spill port and fuel tanks are set above the valve body.Between two asphalt channels (hyperbaric chamber), be provided with a guiding valve 12, make pressure test mouth 22 be communicated with a shared oil pocket, by plug screw 19 setting pressure tables, can test system pressure at the pressure test mouth.

When system works, two-way oil pump sucks oil from fuel tank, enter asphalt channel by asphalt channel X import and Y import, promote scavenger valve 10 and commutation stage clip 9, pressure oil promotes hydraulic control spool 3 by the hydraulic control mouth simultaneously, open ball valve 5, make oil enter oil cylinder, thereby realize to-and-fro motion by X1, Y1 mouth.Relief valve is located on the working connection of asphalt channel X-X1 and Y-Y1 in the bottom of Pilot operated check valve, by jam nut, voltage regulation screw, can freely adjust pressure.Series flow control valve is located on the oil circuit, can freely adjust oil mass to reach the requirement of speed governing.The pressure test mouth is established between two asphalt channels, and X-X1 oil circuit working pressure oil promotes guiding valve and opens the straight-through pressure gauge of oil circuit, can measure the pressure on X-X1 road, otherwise surveys the pressure on Y-Y1 road.
