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 being applied to accumulator by multiple oil circuit and multiple valve elements combination.
Background technique
Often accumulator can be used at hydraulic system back warp; particularly in Large Hydraulic System; accumulator is often multiple to be used simultaneously, forms an Accumulator arrangements, and each accumulator filler opening generally needs design fuel inlet ball check valve; control the closedown of accumulator and open; a fuel outlet ball valve, act as the fluid bled off in accumulator, also designs a relief valve simultaneously; in order to avoid the pressure superelevation of accumulator, damage the leather bag of accumulator.When changing accumulator, needing fuel inlet ball check valve to close, opening fuel outlet ball valve, tighten relief valve, can accumulator be changed.Energy accumulator housing is that a casting forms round can shape, and upper and lower two ends are camber line.Upper end is inflatable interface, lower end is oil-feed interface, the installation of accumulator has requirement, General Requirements is placed vertically and is fixed on 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 hole, and its following camber line face just supports accumulator, the accumulator first half must need installation clip that it is fastened on accumulator frame simultaneously, prevents it from rocking.The hydraulic fluid port of accumulator, the most beneath, is connected with accumulator control valve assembly pipe, and control valve group is connected with the stagnation pressure solenoid P of system and return tube T again.Can be there is following problem in such mounting type: one, cast out because accumulator and accumulator frame support the camber line face coordinated, the perforate of accumulator frame simultaneously has also generally been cut by flame, its precision can only be leaned on the technical ability of workman to control, so the assembly precision of accumulator and accumulator frame is difficult to ensure, this is different with regard to causing the piping length between accumulator and accumulator valve group, repeatability is very poor, very difficult when accumulator damage will be changed, some just cannot be changed; Its two, because pipe arrangement interface is various, very large to line shock when accumulator topping up and tapping, often there is the oil impregnate even phenomenon such as booster.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of control safety valve facilitating accumulator to install, change.
The technical solution adopted for the present invention to solve the technical problems is: a kind of control safety valve of plate type energy accumulator, be made up of valve body, described valve body forms oil circuit P and oil circuit T two oil circuits by holing or casting, one end of described oil circuit T is closed, oil-feed stopper is provided with at the oil inlet end of described oil circuit P, oil circuit P oil-feed stopper oil outlet to oil circuit P oil outlet between be provided with two bypasses and oil circuit T connects, a bypass is provided with by plug stopper of draining the oil wherein, another bypass is provided with safety overflow.
As the improvement of technique scheme, described oil-feed stopper is consistent with described stopper structure of draining the oil, and is made up of handle, spheroid and rotating shaft, described handle is arranged in rotating shaft, described rotating shaft is connected with spheroid, and the rotational of rotating shaft drives spheroid to rotate, and described spheroid is provided with a through hole; Between described spheroid and rotating shaft, be provided with seal bowl, described rotating shaft is provided with stop pad, described valve body is provided with locating stud.
As another improvement of technique scheme, described safety overflow is by valve pocket, spool, adjusting screw rod, spring seat and spring composition, described valve pocket is the cylindrical body of hollow, be arranged on valve body by screw thread, valve pocket front-end face center is provided with an oil inlet hole, the circumferential surface of valve pocket has oil outlet, in described valve pocket, spring seat is installed, described spring seat is provided with spring, in the front end of spring, taper valve core is installed, the conical surface of spool is pressed on oil inlet hole end face by described spring, form conical surface seal, by screw thread, adjusting screw rod is installed in the rear end of described valve pocket, spring seat is withstood in the front end of described adjusting screw rod.Described spool is coaxial with valve pocket.
The invention has the beneficial effects as follows: due to control safety valve of the present invention and accumulator connection and all have employed board-like linkage structure with the connection of main line, without 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.
