Abstract
The invention discloses a friction ring type water sealing device, which consists of a friction ring (1) and a water sealing seat (2), wherein the friction ring (1) is made of a polytetrafluoroethylene material; the water sealing seat (2) is provided with a water sealing annular groove (21) of which the diameter and width are greater than those of the friction ring (1); the friction ring (1) is arranged in the water sealing annular groove (21) and is in sliding fit with a shaft (4); the outer side face (11) of the friction ring (1) is in smooth fit with the side end face (23) of the water sealing annular groove (21); the friction ring (1) is driven by the shaft to rotate together with the shaft; and under the action of pressure of water in a cavity of a gland, the outer side face of the friction ring (1) is closely attached together with the side end face of the water sealing annular groove (21) to perform sliding friction rotation, so that a friction sealing matched end face is formed to stop leakage of water.
Description
Affiliated technical field
What the present invention relates to is water seal arrangement, i.e. shaft sealer.
Existing technology
The existing technology axial end i.e. water seal arrangement at axle and gland place has rubber lip type circle formula, mazy type, forms such as distinguish ring type; Various structures have its oneself characteristics, but deficiency is also arranged, and lip type circle, mazy type is not wear-resistant; Life-span is shorter, and distinguish ring type sealing structure for water is complicated, and cost is higher; The sealing of the various water seals of existing technology and wearability, working life is lower, needs frequent repair and replacement.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, low cost of manufacture, easy to install, good airproof performance, the water seal arrangement of long service life.
The present invention
Friction ring type water seal arrangementConstitute by water seal body friction ring 1 and water seal seat 2; Friction ring 1 is processed by high-abrasive material; Water seal seat 2 constitutes for the member that is fixedly connected with gland or by gland 3 bodies, on water seal seat 2, offers axis hole and water seal circular groove 21, has opening 20 in the inboard of this water seal circular groove 21; The diameter of water seal circular groove 21 and width are greater than the diameter and the width of friction ring 1; Friction ring 1 is installed in the water seal circular groove 21, and friction ring 1 slidably cooperates with axle 4, for the sealing that improves friction ring 1 and between centers offers maze trough 10 on the internal diameter of friction ring 1; The anti-leakage of sealing between friction ring 1 and running shaft, the side end face 23 of the outer side surface 11 of friction ring 1 and the water seal circular groove 21 of water seal seat 2 are that higher surface finishment and planeness cooperates.When axle 4 revolved, friction ring 1 was driven by axle 4 and rotates together with the axis, and under the pressure effect of gland 3 inner chamber water, the sliding friction that fits together closely of the outer side surface 11 of friction ring 1 and the side end face 23 of water seal circular groove 21 is rotated, and forms friction sealed counterface.
The present invention is simple in structure, compact, and low cost of manufacture is easy to install.The outer side surface 11 of friction ring 1 and the water seal circular groove of water seal seat 2 21 side end faces 23 form friction sealed cooperations, water under the centrifugal action of friction ring 1 quilt to impetus radially, under high rotational speed; The end face closing force that this centrifugal force and water pressure form has effectively prevented the leakage of water, thereby reaches good sealing effect, and abrasion resistance properties is good; Long service life; Friction ring 1 floats with axle, and friction ring 1 work does not receive that the axle string is moving to be influenced, and has enlarged the using scope and the adaptability of water seal; And anti-dry grinding performance is good; Even occur at cooling water under the situation of cutout or no-cooling-water, friction ring 1 also can proper functioning, and cause thermal damage can not occur.
Friction ring 1 is polytetrafluoroethylmaterial material or modified Teflon material, has certain elasticity, can produce certain deformation, and friction ring 1 is installed in through compressive strain in the water seal circular groove 21 of water seal seat 2, installs simply, and it is convenient to change, good economy performance.
The Ben Mingfa compact structure is specially adapted to use on the equipment of compact structure, and especially using as the cooling water sealing of cooperative mechanical sealing has good effect.
