Abstract
The invention discloses a double end face machine seal which is composed of a medium end seal and an atmosphere end seal. The double end face machine seal comprises two rotating shafts wrapped by the two seals and a flange disk arranged at the lower end of a main body. A medium end static ring is arranged in the flange disk in a floating mode so as to be parallelly attached to the sealing face of a medium end moving ring. Good sealing performance is achieved. The double end face machine seal is not provided with a cooling clamping sleeve and a bearing, so that redundant substance pollution materials are not added. The double end face machine seal is small in size, convenient to carry, and convenient to operate due to the fact no rack needs arranging in addition at actual utilization time.
Description
Technical field
The present invention relates to a kind of seal arrangement, be specifically related to a kind of double mechanical seal.
Background technique
At present, glassed steel reaction vessels is to contain the glass of high silicon dioxide in the prior art, lining is at the internal surface of Steel Vessel, through high temperature sintering and securely adherence becomes composite product on the metal surface, it has the stability of glass and the two-fold advantage of metal strength, it is a kind of good corrosion resistant apparatus, existing vesselseals is all with cooling jacket and bearing, in cooling jacket, to pass into the effect that cold water reaches cooling, and bearing must add lubricant oil, so just have an opportunity to the material contamination in the reactor, and this mechanical seal volume and weight is all very large, is inconvenient to carry, in addition, need other installation frame during the actual use of existing mechanical seal, then in frame speed reducer and motor are installed, operation is trouble comparatively.
Summary of the invention
The objective of the invention is provides a kind of double mechanical seal in order to overcome the deficiency of prior art existence, and it does not have cooling jacket and bearing, can not add unnecessary material contaminated materials, and the little convenient carrying of volume does not need to settle in addition frame, easy-to-operat during actual the use.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of double mechanical seal, its main body is comprised of media end sealing and atmosphere end sealing, and comprise by above-mentioned two flange plate that seal the rotating shaft of surrounding and be located at the main body lower end, it is characterized in that described media end sealing comprises is located at rotating shaft lower end and the floating media end rotating ring that is loaded on the media end stationary ring in the described flange plate and is located at this stationary ring top; It is peripheral that the sealing of described atmosphere end comprises that atmosphere end stationary ring and atmosphere end rotating ring, described atmosphere end stationary ring and atmosphere end rotating ring are located at the middle part of described rotating shaft, and stationary ring places the top of rotating ring, and the lower end of rotating ring is connected with a spring.
Preferably, described media end rotating ring, media end stationary ring, atmosphere end rotating ring and the atmosphere end stationary ring outside all are arranged with O type circle.
Preferably, described double mechanical seal one side is provided with Leak hole, coolant outlet and sealingfluid inlet from top to bottom, and opposite side is provided with oil filling mouth, seal fluid outlet and cooling water inlet from top to bottom.
The invention discloses a kind of double mechanical seal, formed by media end sealing and atmosphere end sealing, and comprising the rotating shaft of being surrounded by above-mentioned two sealings and the flange plate of being located at the main body lower end, the media end stationary ring is floating to be loaded in the flange plate, and stationary ring can parallel to each otherly be fitted to the sealing surface of rotating ring, has good sealing, and do not have cooling jacket and bearing, can not add unnecessary material contaminated materials, the little convenient carrying of volume, do not need to settle in addition frame, easy-to-operat during actual the use.
