Abstract
A 8-shaped compound flat seal gasket is provided with a 8-shaped flat seal gasket which is made of rubber and provided with two connected rings and a trapezoidal-section base, a rectangular-section seal line is arranged on an upper plane of a trapezoid of the base, 8-shaped holders which are made of Teflon materials and fitted with the 8-shaped flat seal gasket are arranged on two sides of the rectangular seal line and on two lateral sides of the trapezoid of the base, and each 8-shaped holder is provided with an inner holder and an outer holder, while connecting ribs are arranged between the inner holder and the outer holder and gaps as wide as the rectangular seal line are reserved between the inner holder and the outer holder. The inner holders and the outer holders made of the Teflon materials are attached to the two lateral sides of the 8-shaped flat seal base made of the rubber, the rectangular seal line is clamped in the gaps between the inner holders and the outer holders, the Teflon materials are hard plastics with higher rigidity, and the 8-shaped compound flat seal gasket cannot deform under higher hydraulic oil pressure when being mounted between an end cap and an oil pump body of a high-pressure oil pump for use.
Description
Technical field
The utility model relates to the supporting planar sealing pad of using of a kind of oil pump, the planar sealing pad of sealing usefulness between particularly a kind of oil pump end cap and the oil pump body.
Background technique
In construction machinery hydraulic system, the oil pump body of high pressure oil pump has adjacent round cavity, the 8 font plane sealing grooves that accent in the adjacent circular is arranged between the end cap of high pressure oil pump and oil pump body, the 8 font planar sealing pads that rubber material is arranged in the 8 font plane sealing grooves, 8 font plane sealings are lined with two continuous annulus, two continuous annulus have journal stirrup radially respectively, it is 8 trapezoidal font plane sealing pedestals that 8 font plane sealings are lined with the cross section, the cross section is that plane sealing pedestal trapezoidal of trapezoidal 8 fonts gone up the plane cross section is arranged is the potted line of rectangle, the cross-section size of 8 font planar sealing pads of this usefulness is less, rubber material is softer, rigidity is less, during use, the higher hydraulic oil of pressure acts on a side of 8 font planar sealing pads, and 8 font planar sealing pads are deformed, and causes seal failure.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of under the higher hydraulic oil effect of pressure, the 8 font composite plane sealing gaskets that can not deform.
The utility model is realized with the following method.
8 font composite plane sealing gaskets
The 8 font planar sealing pads that rubber material is arranged, 8 font plane sealings are lined with two continuous annulus, two continuous annulus have journal stirrup radially respectively, it is 8 trapezoidal font plane sealing pedestals that 8 font plane sealings are lined with the cross section, the cross section is that plane sealing pedestal trapezoidal of trapezoidal 8 fonts gone up the plane cross section is arranged is the potted line of rectangle, on trapezoidal two waists of plane sealing pedestal, there are 8 font holding frames of the polytetrafluoroethylmaterial material that matches with 8 font planar sealing pads the both sides of rectangular seal line, 8 font holding frames have internal frame and outrigger, continuous company's muscle is arranged between internal frame and the outrigger, the gap of matching with the width of the potted line of above-mentioned rectangle is arranged between internal frame and the outrigger, and the internal frame of 8 font planar sealing pad potted lines and the company muscle place between the outrigger have and connect the groove that muscle matches.
The internal frame of the utility model polytetrafluoroethylmaterial material and outrigger are attached on trapezoidal two waists of 8 font plane sealing pedestals of rubber material, the rectangular seal wire clamp is held in the gap between internal frame and the outrigger, polytetrafluoroethylmaterial material is a rigid plastics, rigidity is higher, be installed in when using between the end cap of high pressure oil pump and the oil pump body, under the higher hydraulic oil effect of pressure, can not deform.
Below in conjunction with accompanying drawing, the utility model is further described.
