The sequence acting control valve has the advantages of simple structure, low cost, safe, and convenient and reliable operation.
Description
Technical field
The utility model relates to the control valve of pneumatic cylinder or oil hydraulic cylinder, particularly controls the sequentially-operating control valve that two (group) pneumatic cylinders or oil hydraulic cylinder are docile and obedient preface work.
Background technique
Pneumatic cylinder and oil hydraulic cylinder are widely used in the every field of productive life as power generating apparatus.In some occasion, need two (group) pneumatic cylinders or oil hydraulic cylinder to be docile and obedient preface and carry out work, promptly when the piston of first (group) pneumatic cylinder or oil hydraulic cylinder after upwards moving to terminal point under air pressure or the hydraulic pressure, the piston of second (group) pneumatic cylinder or oil hydraulic cylinder begins upwards operation under air pressure or hydraulic pressure.At present, realize that such sequential working is to adopt the PLC or the time relay to control, but such control mode comparatively complexity and cost are higher.
The model utility content
The purpose of this utility model provides a kind of sequentially-operating control valve, connects in pneumatic circuit or oil hydraulic circuit, is docile and obedient preface and carries out work to control two (group) pneumatic cylinders or oil hydraulic cylinder.
Sequentially-operating control valve described in the utility model comprises valve body and spool, valve body offers step hole along its axis, offering inlet hole and air outlet hole in the valve body side is communicated with macropore in the valve body step hole respectively, and inlet hole is near apart from valve body lower end than air outlet hole apart from valve body lower end, offers gas port at the valve body lower end face and is communicated with described inlet hole.
Spool is the step axle, the step hole and the valve body that are positioned at valve body are slidingly matched, the enlarged diameter section of spool is that the two ends diameter is big, the axis body that mid diameter is little, make between spool and the valve body and form vent slot, when the spool step end face contacted with valve body step hole end face, this vent slot only was communicated with inlet hole, and when spool moved up, this vent slot can be communicated with inlet hole with air outlet hole.
The valve body upper and lower end is respectively arranged with the cover plate that combine as a whole fastening with it, base plate, and cover plate offers mounting hole along its axis, is provided with pressure spring in it, and the lower end of pressure spring acts on the spool upper-end surface; Offering connecting passage on the base plate is communicated with described gas port with aperture in the valve body step hole.
Offer exhaust port on the spool, its opening is respectively on spool upper-end surface and step end face; The mounting hole of cover plate is a step through-hole, is connected with adjusting screw in the aperture in the step through-hole, offers exhaust apertures on the cover plate and is communicated with mounting hole, and the upper end of pressure spring acts on the adjusting screw end face.
This sequentially-operating control valve is connected in gas (liquid) hydraulic circuit, gas (liquid) road is connected with the inlet hole of sequentially-operating control valve with air inlet (liquid) mouth of first gas (liquid) cylinder pressure respectively by branch joint, the air outlet hole of sequentially-operating control valve is connected with air inlet (liquid) mouth of second gas (liquid) cylinder pressure, open gas (liquid) road, under the effect of sequentially-operating control valve, first gas (liquid) cylinder pressure and second gas (liquid) cylinder pressure just can be docile and obedient preface and be carried out work.
Sequentially-operating control valve described in the utility model is simple in structure, with low cost, safe in utilization, convenient and reliable.

Embodiment
Extremely shown in Figure 8 as Fig. 1, this sequentially-operating control valve comprises valve body 5 and spool 12, valve body 5 offers step hole along its axis, offering inlet hole 6 and air outlet hole 4 in valve body 5 sides is communicated with macropore 16 in valve body 5 step holes respectively, and inlet hole 6 is near apart from valve body 5 lower ends than air outlet hole 4 apart from valve body 4 lower ends, offers gas port 7 in valve body 5 lower end surfaces and is communicated with described inlet hole 6.
As shown in Figure 9, this sequentially-operating control valve is connected in gas (liquid) hydraulic circuit, gas (liquid) road is connected with the inlet hole 6 of sequentially-operating control valve with air inlet (liquid) mouth of first gas (liquid) cylinder pressure 19 respectively by branch joint 20, and the air outlet hole 4 of sequentially-operating control valve is connected with air inlet (liquid) mouth of second gas (liquid) cylinder pressure 18.
When working state not, under pressure spring 14 effects, spool 12 step end faces of sequentially-operating control valve contact with valve body 5 step hole end faces, this moment, inlet hole 6 was not communicated with air outlet hole 4, and when opening gas (liquid) road, pressure gas (liquid) body directly enters first gas (liquid) cylinder pressure 19 through branch joint 20, make its piston stroking upward, simultaneously enter sequentially-operating control valve lower end through inlet hole 6, because the effect of the pressure spring 14 of spool 12 upper ends, spool 12 does not produce and moves up.When the piston stroking upward of first gas (liquid) cylinder pressure 19 to terminal after, sequentially-operating control valve lower end air pressure increases, it is up to promote spool 12.When spool 12 went upward to vent slot 10 inlet hole 6 is communicated with air outlet hole 4, pressure gas (liquid) body advanced 4 through air outlet hole and goes into second gas (liquid) cylinder pressure 18, makes its piston stroking upward, thereby realized that two gas (liquid) cylinder pressure is docile and obedient preface and carries out work.A small amount of gas (liquid) body that leaks from spool 12 lower ends can be discharged from the exhaust apertures 13 of valve gap 3 at last through the exhaust port 11 of spool 12, the mounting hole 15 of valve gap 3.
As if needing two groups of pneumatic cylinders of control or oil hydraulic cylinder to be docile and obedient preface work, only need air inlet (liquid) mouth of every group of pneumatic cylinder or oil hydraulic cylinder is carried out respectively and connect getting final product.
