According to the solution, a first one-way valve perpendicular to the upper surface of a valve body is arranged, a first oil way is formed in the side wall of one side of the valve body, one end of the first oil way communicates with the first one-way valve, and the other end of the first oil way extends to the outer side of the valve body and is provided with a first oil opening; a second oil way is arranged between the side wall of the other side of the valve body and the first one-way valve, extends to the outer side of the valve body and is provided with a second oil opening; a second one-way valve parallel to the axis direction of the first one-way valve is arranged on the lower surface of the valve body, and the first one-way valve is connected with the second one-way valve through a third oil way; and a third oil opening is formed in the position, below the second oil opening, of the side wall of the valve body, and the third oil opening communicates with the second one-way valve through a fourth oil way. According to the control valve, the two one-way valves are arranged on one valve body, and the valve body can meet the requirement for sequential stretching and contracting of the sequence oil cylinder through the oil way design.
Description
Technical field
The invention belongs to hydraulic control valve technical field, particularly to order ram control valve.
Background technology
Common engineering oil cylinder when being used in series, due to being affected by frictional force or load, the stretching out and receive of each oil cylinder
Contracting is that do not have sequential, frictional force or the little just first startup optimization of load that is, 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 the control valve block of common oil cylinder is for a hydraulic fluid port and an oil duct it is impossible to satisfaction order oil cylinder order is stretched
The requirement of contracting action.Order oil cylinder is the function of realizing sequential telescopic, and the oil inlet passage when stretching out for the oil cylinder is not used to retract
When drainback passage, hydraulic fluid port is therefore needed on valve block and corresponds to multiple oil ducts.
Content of the invention
Instant invention overcomes the deficiency that prior art exists, there is provided an a kind of hydraulic fluid port correspond to multiple oil ducts, meet suitable
The control valve of sequence oil cylinder sequential telescopic action.
The present invention is achieved by the following technical programs.
Order ram control valve, it includes valve body, oil duct, hydraulic fluid port, the first check valve and the second check valve, and its feature exists
In：Valve body upper surface is provided with the first check valve, valve body side side wall opens up oil duct one, oil duct one one end and first
Check valve turns on, and oil duct one other end extends to outside valve body and is provided with hydraulic fluid port one, and valve body opposite side side wall is unidirectional with first
It is provided with oil duct two, oil duct two extends to and is provided with hydraulic fluid port two outside valve body between valve；Valve body lower surface and the first unidirectional valve shaft
Line direction is abreast provided with the second check valve, and the first check valve is connected by oil duct three with the second check valve；Body wall position
It is provided with hydraulic fluid port three, hydraulic fluid port threeway oil channel four and the conducting of the second check valve below hydraulic fluid port two.
Further, described oil duct one axis direction and the first one-way valve axis direction are mutually perpendicular to.
Further, described first one-way valve axis are coplanar with the second one-way valve axis but not conllinear.
Further, described oil duct two axis direction and oil duct four axistyle direction are parallel to each other.
The present invention compared with prior art has the advantages that.
The control valve that the present invention provides arranges two check valves on a valve body, enables valve body by oil duct design
The demand of satisfaction order oil cylinder sequential telescopic.
