The invention discloses a constant-proportion pressure distribution valve with variable-width pressure equalizing grooves. A main valve is arranged in the main valve body, the main valve body comprises a main valve sleeve, a main valve element, a guide push rod and a first spring, the main valve sleeve is arranged at the front end and provided with an opening communicated with an oil inlet P, the main valve element is arranged in the center of the main valve sleeve and extends out of the main valve sleeve towards the rear end, and the rear end of the main valve element abuts against the rear end of the main valve sleeve. The front end of the guide push rod abuts against the rear end of the main valve sleeve. A first spring is arranged at the rear end of the guide rod. A process hole channel outside the main valve sleeve is communicated with a fourth oil way, and an outer leakage oil way is arranged at the rear end of the main valve element and connected with an outer leakage opening Y opening; a plurality of pressure equalizing grooves are formed in the outer wall face, making contact with the main valve sleeve, of the main valve element and the outer wall face, making contact with the inner wall of the first oil way, of the guide push rod, and the widths of the pressure equalizing grooves are continuously increased in the direction from the oil outlet B to the oil inlet P. The constant-proportion pressure distribution valve has the beneficial effects that the width of the pressure equalizing groove is changed, so that the elimination clamping force at an inlet is maximum, and the elimination clamping force at an outlet is minimum. And the width of the pressure equalizing groove is continuously increased, so that the action response of the main valve element is sensitive, and the optimal effect is rapidly achieved.

    本发明公开了一种均压槽宽度变化的定比压力分配阀。主阀设置在主阀体内,主阀体包括主阀套、主阀芯、导向推杆、第一弹簧,所述主阀套设置在前端,主阀套设置开口与进油口P连通,所述主阀芯设在主阀套中心并向后端延伸出主阀套,主阀芯后端抵靠主阀套的后端,导向推杆前端抵靠在主阀套的后端,导向杆后端设置第一弹簧;主阀套外的工艺孔道与第四油路相通,主阀芯后端设置有外泄油路与外泄口Y口相连;所述主阀芯与主阀套接触的外壁面和导向推杆与第一油路内壁接触的外壁面上开有多道均压槽,从出油口B到进油口P的方向,均压槽的宽度不断增加。本发明的有益效果在于通过设置均压槽宽度变化,使得进口处的消除卡紧力最大,出口最小。通过设置均压槽的宽度不断增加,使得通过使主阀芯动作响应灵敏迅速达到最佳的效果。
