Technical Field
The utility model relates to the technical field of sealing elements, in particular to a novel elliptical head end cover sealing structure.
Background
The original old elliptical head end cover adopts a radial sealing step structure, and has good sealing effect and positioning. But this structure still has drawbacks. When the pump body runs to reach a specified stroke, hard particle materials are arranged between the piston head and the end cover of the head, the piston head is clamped, so that the piston head is stressed to cause damage of the piston head and fracture of the piston rod, and the inventor improves the process.
Disclosure of Invention
The utility model aims to provide a novel elliptical head end cover sealing structure which reduces processing time and saves materials and can prevent a piston head from clamping.
In order to achieve the aim of the utility model, the novel elliptical head end cover sealing structure adopts the following technical scheme:
a novel elliptical head end cover sealing structure, comprising:
the cylinder body is provided with a cavity communicated with the cylinder body along the axial direction;
the piston assembly is encapsulated in the cylinder body and comprises a piston rod and a piston head, the piston head is sleeved on the piston rod, and the side wall of the piston head presses against the inner wall of the cavity; and
the seal head assembly is arranged on one side of the cylinder body and comprises an arc seal head, the outer side of the arc seal head is provided with a connecting flange, the connecting flange is detachably arranged on the cylinder body through a bolt, an oblique angle is arranged on one side, opposite to the piston assembly, of the connecting flange, and the oblique angle is attached to the inner wall of the cavity. The novel elliptical head end cover adopts an end face mounting and sealing structure, and the structure cancels a positioning step. On the one hand, the processing time can be reduced, the material can be saved, on the other hand, the distance between the pump body and the end face can reach 50mm under the condition that the stroke of the pump body reaches the specified requirement, and the maximum particle diameter of the feeding of the equipment is not more than 30mm. At this time, the piston head is not blocked in the material. Moreover, the inclined opening on the end face of the end socket can push materials out of the end socket more easily.
The utility model relates to a novel elliptical head end cover sealing structure which is further improved in that a sealing gasket is arranged at the joint of a bolt and a cylinder body.
The utility model relates to a novel elliptical head end cover sealing structure which is further improved in that a sealing ring is arranged between a piston head and a cavity.
Compared with the prior art, the utility model has the beneficial effects that:
the novel elliptical head end cover adopts an end face mounting and sealing structure, and the structure cancels a positioning step. On the one hand, the processing time can be reduced, the material can be saved, on the other hand, the distance between the pump body and the end face can reach 50mm under the condition that the stroke of the pump body reaches the specified requirement, and the maximum particle diameter of the feeding of the equipment is not more than 30mm. At this time, the piston head is not blocked in the material. Moreover, the inclined opening on the end face of the end socket can push materials out of the end socket more easily.
