Description
Technical field
The present invention relates to a kind of control safety valve for hydraulic equipment, be specifically related to a kind of valve element that is applied to accumulator that is formed by a plurality of oil circuits and a plurality of valve elements combination.
Background technique
Often can use accumulator at the hydraulic system back warp; particularly in the Large Hydraulic System; accumulator is often a plurality of to be used simultaneously, forms an Accumulator arrangements, and each accumulator filler opening generally need to design a fuel inlet ball check valve; control closing and opening of accumulator; a fuel outlet ball valve act as the fluid that bleeds off in the accumulator, also designs simultaneously a relief valve; in order to avoid the pressure superelevation of accumulator, the leather bag of damage accumulator.When changing accumulator, need to close fuel inlet ball check valve, open fuel outlet ball valve, tighten relief valve, can change accumulator.Energy accumulator housing is that a casting forms the round can shape, and two ends are camber line up and down.The upper end is inflatable interface, the lower end is the oil-feed interface, the installation of accumulator has requirement, General Requirements is placed vertically and is fixed on the accumulator frame, the dunnage of accumulator frame has a hole less than accumulator maximum outside diameter, and accumulator is holded up to be inserted in the hole, and its following camber line face just supports accumulator, the while accumulator first half must need to install clip it is fastened on the accumulator frame, prevents that it from rocking.The hydraulic fluid port of accumulator is connected with accumulator control valve assembly pipe the most beneath, and the control valve group is connected with return tube T with the stagnation pressure solenoid P of system again.Can there be following problem in such mounting type: one, because accumulator supports the camber line face that cooperates with the accumulator frame and casts out, the simultaneously perforate of accumulator frame is also generally finished by flame cutting, its precision can only lean on workman's technical ability to control, so the assembly precision of accumulator and accumulator frame is difficult to guarantee, this is different with regard to causing the piping length between accumulator and the accumulator valve group, repeatability is very poor, very difficult when the accumulator damage will be changed, some just cannot be changed; Its two very large to line shock when accumulator topping up and tapping because the pipe arrangement interface is various, the phenomenons such as oil impregnate even booster often occur.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of control safety valve that makes things convenient for accumulator to install, change.
The technical solution adopted for the present invention to solve the technical problems is: a kind of board-like accumulator control safety valve, formed by valve body, form oil circuit P and two oil circuits of oil circuit T at described valve body by boring or casting, the end sealing of described oil circuit T, oil inlet end at described oil circuit P is provided with the oil-feed stopper, oil circuit P connects to being provided with two bypasses and oil circuit T between the oil outlet of oil circuit P at the oil outlet of oil-feed stopper, by plug the stopper of draining the oil is installed in a bypass therein, is provided with safe overflow mechanism in another bypass.
As improvement of the technical scheme, described oil-feed stopper is consistent with the described stopper structure of draining the oil, and is comprised of handle, spheroid and rotating shaft, described handle is installed in the rotating shaft, described rotating shaft is connected with spheroid, and the rotational of rotating shaft drives the spheroid rotation, and described spheroid is provided with a through hole; Between described spheroid and rotating shaft, be provided with seal bowl, be provided with stop pad in described rotating shaft, be provided with locating stud at described valve body.
Another improvement as technique scheme, described safe overflow mechanism is by valve pocket, spool, adjusting screw rod, spring seat and spring form, described valve pocket is the cylindrical body of hollow, be installed on the valve body by screw thread, valve pocket front-end face center is provided with an oil inlet hole, circumferential surface at valve pocket has oil outlet, in described valve pocket, spring seat is installed, at described spring seat spring is installed, front end at spring is equipped with taper valve core, and described spring is pressed on the oil inlet hole end face with the conical surface of spool, forms conical surface seal, rear end at described valve pocket is equipped with adjusting screw rod by screw thread, and the front end of described adjusting screw rod withstands spring seat.Described spool is coaxial with valve pocket.
The invention has the beneficial effects as follows: because being connected and all having adopted board-like linkage structure with being connected of main line of control safety valve of the present invention and accumulator, there has not been middle pipe arrangement pipeline, the installation of very convenient like this accumulator, replacing or exchange, simultaneously, whole valve group good seal performance, interface is few, greatly reduces the possibility of leakage of oil oil impregnate.
