Abstract
The invention belongs to the field of mechanical sealing and particularly relates to a novel mechanical sealing device with two radial end faces for a kettle. According to the novel mechanical sealing device with the two radial end faces for the kettle, a wedge-shaped loop sealing ring adopted by an original inner static loop is replaced by an O-shaped sealing ring, and a O-shaped supporting loop is additionally arranged below the O-shaped sealing ring; when the sealing hydraulic pressure is zero, a sealing surface of the inner static loop cannot be opened due to the fact that the counter-pressure area accounts for over 75% of the contact area. The novel mechanical sealing device with the two radial end faces for the kettle has the beneficial effects of being suitable for chemical industries, low in cost, safe and reliable. By the adoption of the novel mechanical sealing device with the two radial end faces for the kettle, the problem that according to an original sealing device, an inner mechanical sealing surface is opened when an emergency situation occurs, and consequentially harmful gas in the kettle leaks can be completely solved. It is proved through the practice that the sealing device can be used for production and scientific experiments of chemical enterprises and is completely feasible in the aspects of technique, economical efficiency and environmental friendliness.
Description
Technical field
The invention belongs to mechanical seal field, particularly relate to novel radial direction double end-face mechanical sealing device for cauldron.
Background technique
Mechanical sealing element technology is widely used in the fields such as national defence, electric power, chemical industry, oil, metallurgy, communications and transportation, medicine, food, cosmetics, the application of novel radial direction double end-face mechanical sealing device for cauldron is an importance in mechanical seal field, belongs to a kind of mechanical sealing device for cauldron.Novel radial direction double end-face mechanical sealing device for cauldron uses more at chemical enterprise, its boundary dimension and axial Double End vesselseals basically identical, and about being highly only the half of axial Double End vesselseals, therefore price is lower, it is the first-selected product of chemical enterprise.Traditional radial direction double end-face mechanical sealing device for cauldron, needs during work to select sealing liquid station to provide higher than still internal pressure and the sealing fluid circulated, lubricates and dispel the heat to mechanical seal.Axial Double End vesselseals generally adopts liquid container and recirculated cooling water lubricate mechanical seal and dispel the heat.The price comparison of sealing liquid station is expensive, and axial Double End vesselseals adds liquid container, and price is also very expensive.At present, some chemical enterprises adopt high-pressure service pump to provide sealing fluid to radial direction double end-face vesselseals, and a high-pressure service pump provides sealing fluid (the general water that adopts is as sealing fluid) can to 4-5 platform radial direction double end-face vesselseals, so, radial direction double end-face vesselseals adds that the price of a high-pressure service pump is lower, is applicable to current chemical enterprise.But provide sealing fluid to there is a problem with high-pressure service pump, exactly once power failure or high-pressure service pump have had fault, sealing liquid pressure reduces to zero immediately, and now inner sealing surface is opened immediately and caused inflammable and explosive or poisonous, poisonous gas leakage in still.Novel radial direction double end-face mechanical sealing device for cauldron solves the problems referred to above, improves manufacturing efficiency, provides cost savings, and has ensured the safety of product, and the prodution and development for chemical enterprise provides facility and ensures.
Summary of the invention
Main purpose of the present invention is the deficiency overcoming above-mentioned technology, and provides novel radial direction double end-face mechanical sealing device for cauldron.This device may be used on chemical enterprise reactor still top, technically, economically with environmental protection is all feasible.
The present invention for achieving the above object, by the following technical solutions: novel radial direction double end-face mechanical sealing device for cauldron, use cambridge ring seal ring used for former interior stationary ring instead O-ring seals, and an O shape circle filler ring is added in O-ring seals bottom, interior stationary ring part is when sealed fluid pressure is zero, because area of counter pressure accounts for more than 75% of area of contact, therefore sealing surface is not opened.
Beneficial effect: novel radial direction double end-face mechanical sealing device for cauldron perfect performance, be applicable to chemical enterprise, cost is low, safe and reliable.Utilize novel radial direction double end-face mechanical sealing device for cauldron, can solve former seal arrangement completely under emergency situations, mechanical seal inner sealing surface opens the problem of poisonous gas leakage in the still that causes.Facts have proved, this seal arrangement may be used for Production in Chemical Plant and scientific experiment, technically, economically with environmental protection is all feasible.Have the following advantages:
1. design of the present invention, adopts complete unit loading type structural design, realizes quick position and installs, and solves when former radial double mechanical seal is installed and forgets clipping room spacer ring, cambridge ring, need the problem reinstalled, highly effective and safe, save financial cost.
2. design of the present invention, interior sealing adopts O type circle to add filler ring structure, and solve seal failure when sealing liquid pressure is zero and cause sealing surface to open, the problem of poisonous gas leakage in still, is applicable to the explained hereafter of harmful gas in reactor.
3. design of the present invention, be applicable to subzero 20 degrees Celsius to 200 degrees Celsius, weak erosive liquid medium, 1.6Mpa with downforce, rotating speed is maximum reaches 1000r.p.m.
Accompanying drawing explanation
Accompanying drawing 1 is structural drawing of the present invention.
Accompanying drawing 2 is cut-away views of the present invention.
Accompanying drawing 3 be conventional radial Double End still sealing structural drawing.
Accompanying drawing 4 is cut-away views of conventional radial Double End still sealing.
Embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.Its structural drawing is as shown in Figure of description.Novel radial direction double end-face mechanical sealing device for cauldron, uses cambridge ring seal ring used for former interior stationary ring instead O-ring seals, and adds an O shape circle filler ring in O-ring seals bottom.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
