Abstract
The utility model relates to an inflammable gas explosion-proof fan shaft water sealing device, composed of an internal sleeve, a sealing water channel base, a front water channel, a sealing water channel, a rear water channel and a constant pressure water chamber, wherein, the internal sleeve is arranged on an axle of the fan and sheathed with the sealing water channel base; the front water channel, the sealing water channel and the rear water channel are arranged between the sealing water channel base and the internal sleeve, the constant pressure water chamber is arranged on the sealing water channel base which is arranged between the sealing water channel and the rear water channel, the inner wall of the front water channel, sealing water channel and the rear water channel is provided with flutes, and the internal sleeve is provided with toroidal pointed teeth. The utility model has the advantage of good sealing effect, and can efficiently prevent the external leakage of the inflammable gas, and therefore, demolition accidents can be avoided occurring.
Description
The utility model belongs to machinery manufacturing technology field, is a kind of blower fan shaft seal.
Existing blower fan shaft seal generally adopts machinery type to seal, and when the axle that is used for inflammable gas flame proof blower fan was gone up, sealing effect did not reach usage requirement, has inflammable gas generation leakage situation, thereby causes demolition accident.
The purpose of this utility model is that a kind of blower fan shaft seal that can prevent gas leakage will be provided.
Solution of the present utility model is a cover in adopting, sealing water cavity seat, preceding water cavity, the sealing water cavity, back water cavity and constant voltage hydroecium constitute inflammable gas flame proof blower fan axle water seal arrangement, cover is installed on the axle of blower fan wherein, be set with sealing water cavity seat interior putting, between sealing water cavity seat and interior cover, preceding water cavity is housed, the sealing water cavity, back water cavity, preceding water cavity, the sealing water cavity, back water cavity is respectively in the front portion that seals the water cavity seat, centre and rear portion, sealing water cavity seat between sealing water cavity and the back water cavity is provided with the constant voltage hydroecium, preceding water cavity, the sealing water cavity, be equipped with the groove of ring-type on the inwall of back water cavity, have on the outer wall of interior cover and the corresponding hoop pointed tooth of groove.During use, to constant voltage hydroecium fills with water, make constant voltage hydroecium and sealing water cavity be in slight positive pressure state, itself and outside atmosphere is isolated, when axle turns round, with the interior cover drive water rotation of axle rotation synchronously, the viscosity ability effect that the groove ring surface of the surface of interior cover pointed tooth and sealing water cavity forms, play good sealing effect, stoped leaking of inflammable gas safely.
The utlity model has good sealing effect, can prevent leaking of inflammable gas effectively, thereby avoid the generation of demolition accident.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is a sectional view of the present utility model.
The utility model is by interior cover 2, sealing water cavity seat 3, preceding water cavity 4, sealing water cavity 5, back water cavity 6 and constant voltage hydroecium 7 constitute, cover 2 is installed on the axle 1 of blower fan wherein, on interior cover 2, be set with sealing water cavity seat 3, water cavity 4 before between sealing water cavity seat 3 and interior cover 2, being equipped with, sealing water cavity 5, back water cavity 6, preceding water cavity 4, sealing water cavity 5, back water cavity 6 is respectively in the front portion that seals water cavity seat 3, centre and rear portion, sealing water cavity seat 3 between sealing water cavity 5 and the back water cavity 6 is provided with constant voltage hydroecium 7, preceding water cavity 4, sealing water cavity 5, be equipped with the groove 8 of ring-type on the inwall of back water cavity 6, have and groove 8 corresponding hoop pointed tooths on the outer wall of interior cover 2, preceding water cavity 4, sealing water cavity 5, back water cavity 6 is an aluminum material, and interior cover 2 is a copper material.
