Description
Technical field
The utility model belongs to hydraulic control valve technical field, more particularly to a kind of order ram control valve.
Background technology
When being used in series, due to being affected by frictional force or load, each oil cylinder stretches out and receives common engineering oil cylinder
Contracting is that do not have sequential, i.e., the little just first startup optimization of frictional force or load which oil cylinder is subject to.Order oil cylinder can be wanted by design
Realistic existing sequentially-operating, is not affected by frictional force and load.For example：The expanding-contracting action of the telescopic arm on lorry-mounted crane,
Common engineering oil cylinder cannot meet the requirement of sequentially-operating；And order oil cylinder is not affected to make telescopic arm by frictional force and load
By design requirement sequential telescopic.
The excessively oily passage of valve block that controls of common oil cylinder is a hydraulic fluid port and an oil duct, it is impossible to which satisfaction order oil cylinder order is stretched
The requirement of contracting action.Order oil cylinder is the function of realizing sequential telescopic, and oil inlet passage of the oil cylinder when stretching out is not used to retract
When drainback passage, therefore the multiple oil ducts of hydraulic fluid port correspondence are needed on valve block.

The utility model overcomes the deficiency of prior art presence, there is provided an a kind of hydraulic fluid port corresponds to multiple oil ducts, expires
The control valve of sufficient order oil cylinder sequential telescopic action.
The utility model is achieved by the following technical programs.
A kind of order ram control valve, it includes valve body, oil duct, hydraulic fluid port, the first check valve and the second check valve, its feature
It is：Valve body upper surface is provided with the first check valve, oil duct one is opened up on the wall of valve body side side, one end of oil duct one and the
One check valve is turned on, and the other end of oil duct one extends on the outside of valve body and be provided with hydraulic fluid port one, valve body opposite side side wall and the first list
To oil duct two is provided between valve, oil duct two extends to valve body outside and is provided with hydraulic fluid port two；Valve body lower surface and the first check valve
Axis direction is abreast provided with the second check valve, and the first check valve is connected with the second check valve by oil duct three；Body wall
The lower section of hydraulic fluid port two is provided with hydraulic fluid port three, hydraulic fluid port threeway oil channel four and the second check valve are turned on.
Further, the axis direction of the oil duct one is mutually perpendicular to the first one-way valve axis direction.
Further, first one-way valve axis are coplanar with the second one-way valve axis but not conllinear.
Further, the axis direction of the oil duct two is parallel to each other with oil duct four axistyle direction.
The utility model has the advantages that compared with prior art.
The control valve that the utility model is provided arranges two check valves on a valve body, is designed by oil duct and causes valve body
Disclosure satisfy that the demand of order oil cylinder sequential telescopic.
