Description
Technical field
The utility model relates to a kind of valve body moulding of technical field of mechanical equipment, specifically a kind of 20 tons of excavator hydraulic main valve foundry goods.
Background technique
Excavator is machinery conventional in engineering equipment, and what excavator adopted usually is double loop power limitation control hydraulic system, can realize electrical control and hydraulic control.Hydraulic system is by realizing machinery action to the control of multi-way control valve, the critical piece of hydraulic control system is hydraulic main valve foundry goods, main valve cast-internal oil duct is by oilhole and multi-way control valve, owing to being connected by oil pipe between multi-way control valve with main valve foundry goods, all there is unreliability in its sealing and control mode.
Summary of the invention
The purpose of the present utility model is to provide that a kind of casting accuracy is high, good seal performance has the 20 tons of excavator hydraulic main valve foundry goods installing embedding groove with multi-way control valve.
The utility model is achieved through the following technical solutions:
A kind of 20 tons of excavator hydraulic main valve foundry goods, valve body is the cuboid body of casting of metal material, it is characterized in that: valve body both sides are provided with oilhole, oilhole is connected with the runner in valve body, oilhole connects multi-way control valve, both sides oilhole symmetry is through, the oilhole number of both sides is 5, oilhole is evenly arranged in groove, and the top of groove is provided with the installation embedding groove of multi-way control valve, and embedding groove has 2,1 is U-shaped embedding groove, another is circular embedding groove, circular embedding groove and straight trough through, side valve body is provided with 3 installation screws; The U-shaped embedding groove that 5 are installed multi-way control valve is provided with above the groove of the opposite side of valve body; There are 2 filler openings one side end face of valve body, two ends have circular groove, another side has the step trough of indent, and the installation embedding groove of valve body both sides is convenient to multi-way control valve and is directly installed connection, improves sealing and the reliability of connection.
The utility model has following beneficial effect:
1. casting accuracy is high;
2. connect reliable;
3. good seal performance.
