Abstract

The utility model discloses a hydraulic diverter valve in the field of synchronous hydraulic valves. A valve plug of the valve is a slide valve having an integrated structure with the middle recessed inward; the valve plug is provided with symmetrical fixed orifices communicated with an oil inlet and symmetrical variable orifice groups communicated with oil outlets through valve body under cut grooves. By employing the valve plug with the integrated structure instead of a two-body type valve plug, and with the organic coordination of the fixed orifices and the variable orifice groups, the hydraulic diverter valve has novel conception and a simple and reasonable structure, simplifies technology process, is easy to process and manufacture, has stable working performances, improves production efficiency, reduces production cost and is suitable for promotion in the industry.

Description

A kind of hydraulic synchronizing valve

Technical field: the utility model relates to a kind of hydrovalve, particularly relates to the diverter valve in a kind of Hydraulic Synchronizing Valve.

Background technique: at present, in the hydraulic system synchronous control mode of executive component have multiple, like synchronous motor, mechanical forced, Proportional valve, servovalve, synchronous valve and emerging digital valve or the like.Wherein the formation of equivalent shunting, proportional diverting and the synchro system of synchronous valve is more simple than other.However, the structure of diverter valve or more complicated.Wherein structure relatively simply is processed into identical two with spool at last and colludes couplet formula structure or be installed in two reversing piston formula structures in the flip sleeve.See that from domestic disclosed patent situation the number of general component processing is more, and required precision is also all very high, precision is 1-3%.So, can be under the prerequisite of the shunting precision that keeps existing product, simplified structure makes it to be easier to manufacturing as far as possible, will be significant to commercial production and practical application.It simultaneously also is the technical barrier that solution is thirsted in this field.

Summary of the invention: the purpose of the utility model is to provide a kind of hydraulic synchronizing valve, mainly is the complex structure that exists in the existing technology in order to solve, and is difficult for the problem of manufacturing.

The technological scheme of the utility model is described below: this model utility comprises valve body, spool, filler opening, oil outlet, Returnning spring, seal ring, big plug screw; Said spool be in the middle of the inside guiding valve of recessed integral structure, the variable orifice crowd who on spool, is arranged with the fixed orifice that communicates with filler opening and communicates with oil outlet through the undercut groove of valve body.

This model utility has been owing to taked said structure, changes over the structure of double-body bike spool, adds organic cooperation of fixed orifice and variable orifice crowd, makes the structure of this model utility simpler, thereby simplified technological process, convenient manufacturing.Have product conception novelty, stable work in work simultaneously, enhance productivity, reduce production costs, be fit to advantages such as popularization in the industry.

Description of drawings:

Fig. 1 is the structure sectional view of hydraulic synchronizing valve;

Fig. 2 is the side view of Fig. 1.

Embodiment: by Fig. 1, hydraulic synchronizing valve shown in Figure 2 is improved a kind of novel synchronous valve on the existing technology basis.Its outside is a valve body 1, and valve body 1 is provided with two oil outlet A, the B of oil inlet P and symmetry.In valve body 1 passage, be spool 2, said spool 2 be in the middle of the inside guiding valve of recessed integral structure, the variable orifice crowd 7 who on spool 2, is arranged with the fixed orifice 6 that communicates with oil inlet P and communicates with oil outlet A, B through the undercut groove 8 of valve body 1.Said fixed orifice 6 is a throttling part of the utility model, and constitutes the second throttle part by the undercut groove 8 on variable orifice crowd 7 and the valve body.Spool 2 two ends are Returnning springs 3, and Returnning spring 3 is spacing by the set big plug screw in valve body 1 passage two ends 5.

During the utility model work; Pressure oil gets into from oil inlet P; Be divided into two through bilateral symmetry, the identical fixed orifice 6 in aperture and get into left and right sides oil pocket; Undercut groove (being annular groove) 8 on symmetrical variable orifice crowd 7, valve body 1 is again flowed out by oil outlet A, B and to get into executive component.As two oil outlet A, when B pressure is identical, about two oil pocket pressure equate that because identical to equidistributed fixed orifice 6 liquid resistance, this moment, two oil outlet A, B flow were identical.When wherein any oil outlet A or B pressure rise (when load strengthens); Rising improves A side oil pocket oil pressure like oil outlet A pressure, and spool 2 moves to right side shown in Figure 1, and the area that variable orifice crowd 7 hides undercut grooves 8 reduces; Meanwhile; Oil outlet B side oil pocket masked area increases, and pressure raises, and finally reaches A, B both sides oil pocket pressure equates.Two oil outlet A, B flows recover to equate at this moment.When diverter valve quit work, spool 2 recovered the home position under 3 effects of two ends Returnning spring, prepare for work next time.

Claims

1. hydraulic synchronizing valve; Comprise valve body (1), spool (2), filler opening, oil outlet, Returnning spring (3), seal ring (4), big plug screw (5); It is characterized in that: said spool (2) be in the middle of the inside guiding valve of recessed integral structure, on spool (2), be arranged with the variable orifice crowd (7) that the fixed orifice (6) that communicates with filler opening and the undercut groove (8) through valve body (1) communicate with oil outlet.
