The hydraulic machine material injection controllable one-way valve has the advantages that the phenomenon of backflow of the materials can be prevented well by matching the steel ball with the seal base.
Description
Technical field
The utility model relates to a kind of wet type powder magnetic material special hydraulic press material feeding controllable check valve, a kind of device that can prevent feed back specifically.
Background technique
Hydraulic press is a kind of take liquid as working medium, is used for transferring energy to realize polytechnic machine.Hydraulic press is except for excellent suitability for press forming, also can be used for correcting, press-fits, packing, briquetting and pressing plate etc.Hydraulic press comprises hydraulic press and oil hydraulic press.Be called hydraulic press take water fluid as working medium, be called oil hydraulic press take oil as working medium.The specification of hydraulic press generally uses nominal working force (thousand Ns) or nominal tonnage (ton) to represent.Mostly forging is hydraulic press with hydraulic press, and tonnage is higher.For reducing equipment size, large-sized forging hydraulic press is commonly used higher pressure (35 MPa left and right), sometimes also adopts ultrahigh pressure more than 100 MPas.The general operating pressure that adopts 6～25 MPas of hydraulic press of other purposes.The tonnage of oil hydraulic press is lower than hydraulic press.
At present, in the prior art, in picture wet type hydraulic press in injecting material, tend to use one-way valve, and in the process using at one-way valve, due to its structure characteristic, in not needing material feeding, it inevitably there will be the phenomenon of feed back, and affects the normal work of hydraulic press.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of wet type powder magnetic material special hydraulic press material feeding controllable check valve that can prevent feed back
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of wet type powder magnetic material special hydraulic press material feeding controllable check valve, and its innovative point is: mainly comprise valve body, horizontal run, steel ball, push rod;
In described valve body, be provided with a horizontal run, be respectively arranged with discharge port and material feeding mouth at the left and right two ends of horizontal run, the side near discharge port in horizontal run is provided with Returnning spring, and the top of Returnning spring is provided with steel ball;
In described horizontal run, be provided with the movable chamber of piston near a side of material feeding mouth, in the movable chamber of piston, be provided with piston, the top of described piston is provided with a push rod that stretches into horizontal run, and piston can drive push rod promote steel ball near or away from discharge port;
The medium position of described horizontal run is provided with sealing seat, and described sealing seat is between steel ball and push rod, and the diameter of steel ball is greater than the diameter of sealing seat middle part circular cavity.
Further, described valve body is made up of left and right two points of valve bodies, has an annular groove parting valve body on the right side near a side that parts valve body on the left side, is embedded in seal ring at annular groove.
Further, described discharge port opening up, material feeding mouth opening down.
The utility model has the advantage of: the discharge port place at one-way valve arranges a steel ball, by coordinating of steel ball and sealing seat, can well prevent the phenomenon of feed back; Valve body adopts split-type structural, facilitates the installation of steel ball; The use of push rod, can guarantee that one-way valve is in the time the situation such as keeping in repair, and keeps one-way valve in normally open.
