Abstract
The invention discloses a kind of mechanical seal device, comprising: sealing ring pedestal, sealing ring base is provided with the endoporus inserted for rotating shaft and the groove installing seal ring; Seal ring, sealing ring is configured in the groove of described sealing ring pedestal; Sealing clamp, sealing pressing plate is provided with establish threaded inner circumferential and the described seal ring of insertion inserted for rotating shaft and forms the convex surface of surface of contact; Regulate fixing pin and connector, this connector is provided with the inner circumferential of inserting for rotating shaft, this adjustment fixing pin is located on described connector, this adjustment fixing pin is fixedly connected with described connector, this adjustment fixing pin is provided with the screw rod of adjustable lengthwise position, and this screw rod blocks described sealing clamp makes sealing clamp and rotatingshaft keep synchronous axial system.The present invention can bear not higher than the elevated-temperature seal of 800 °, and without the need to additional cooling system, both simplifies the structure, and also greatly reduces cost.
Description
Technical field
The present invention relates to a kind of seal arrangement, particularly a kind of mechanical seal device.
Background technique
Current seal arrangement is all generally use at normal temperatures and pressures, and mechanical seal device can bear certain pressure and temperature, its sealing is all to play seal action by O type seal ring, but O type seal ring domestic is at present all the softwood matter such as rubber ring, the temperature of about 120 degree can only be born, and external heatproof the highest also only have 200-300 degree, be difficult to be used in the occasion producing higher temperature, and in order to ensure sealing effect, need additional cooling system to lower the temperature, substantially increase so again the cost of sealing.
Summary of the invention
Goal of the invention: for above-mentioned prior art Problems existing and deficiency, the object of this invention is to provide a kind of resistant to elevated temperatures mechanical seal device.
Technological scheme: for achieving the above object, the technical solution used in the present invention is a kind of mechanical seal device, comprising:
Sealing ring pedestal, sealing ring base is provided with the inner circumferential of inserting for rotating shaft and the groove installing seal ring;
Seal ring, sealing ring is configured in the groove of described sealing ring pedestal;
Sealing clamp, sealing pressing plate is provided with establish threaded inner circumferential and the described seal ring of insertion inserted for rotating shaft and forms the convex surface of surface of contact;
Regulate fixing pin and connector, this connector is provided with the inner circumferential of inserting for rotating shaft, and this adjustment fixing pin is fixedly connected with described connector, and this adjustment fixing pin is provided with the screw rod of adjustable lengthwise position, this screw rod blocks described sealing clamp, makes sealing clamp and rotating shaft keep synchronous axial system.
The material of described seal ring can be graphite or copper etc., both wear-resisting, has again certain hardness.
The convex surface material of described sealing clamp can be high strength polishing metal, reduces the surface friction drag with seal ring surface of contact in rotation process.
The height of described seal ring can be greater than the degree of depth of described sealing ring pedestal groove, making seal ring when loading sealing ring pedestal groove, still can contact well with the convex surface of sealing clamp.
The quantity of described adjustment fixing pin is more than 2 or 2, clamping sealing clamp.
Beneficial effect: the present invention establishes threaded inner circumferential to coordinate with the rotating shaft of inserting mainly through sealing clamp and realizes sealing, do not need the softwood matter using the fusing points such as rubber lower, thus greatly improve the temperature that can bear, can bear not higher than the elevated-temperature seal of 800 °; By fully contacting of the smooth convex surface of seal ring and sealing clamp, reach the effect of sealing further; The position of seal ring of the present invention and sealing ring pedestal is all fixing, and sealing clamp moves with the motion of rotating shaft, its position can be fixed by regulating the screw rod of fixing pin, and when seal wears by regulating this screw rod to regulate the lengthwise position of sealing clamp, make seal ring can continue to use, without the need to changing seal ring immediately because of wearing and tearing, extending the working life of seal ring, effectively reducing the cost of device; Existing machinery seal arrangement is due to the impact of O type seal ring, need additional cooling system to keep sealing effect, and cooling system volume is larger, causing whole device comparatively large, further increase cost, and the present invention is without the need to using O type seal ring, without the need to additional cooling system, therefore the height of whole device is less, and greatly reduce the cost of device, structure is simple.
Accompanying drawing explanation
Fig. 1 is the single structure schematic diagram of mechanical seal device of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, the present embodiment mechanical seal device comprises the cartridge housing 10 of dress bearing, sealing ring pedestal 20, seal ring 30, sealing clamp 40, regulate the parts such as fixing pin 50 and connector 60 composition, wherein sealing ring pedestal 20 is arranged on cartridge housing 10, sealing ring base 20 is provided with the inner circumferential 21 of inserting for rotating shaft (not shown) and the groove 22 installing seal ring 30, seal ring 30 is configured in the groove of sealing ring pedestal, and the height of seal ring 30 is higher than the degree of depth of groove 22, the convex surface 42 of sealing clamp 40 is pressed on seal ring 30, and the internal surface close contact of the convex surface 42 of sealing clamp 40 and seal ring 30, the inner circumferential 41 of sealing clamp 40 is provided with screw thread, this screw thread and rotating shaft close fitting seal, the outer wall of sealing clamp is also provided with multiple projection 43 of dividing equally, screw rod 51 is provided with near the end of two adjustment fixing pins 50 in inverted "L" shaped be oppositely arranged, this screw rod 51 snaps in the gap of two adjacent protrusion 43, play the effect of fixing seal pressing plate, the top of fixing pin 50 is regulated to be respectively equipped with fixed hole 52, connector 60 is located at the top regulating fixing pin 50, this connector 60 is also provided with the inner circumferential 62 of inserting for rotating shaft, connector 60 is also provided with multiple through hole 61, wherein partial through holes 61 regulates the through hole 52 on fixing pin 50 identical in the position of longitudinal direction with being located at, for inserting screw (not shown) secured adjusted fixing pin 50 and connector 60.In the present embodiment, owing to not needing additional bulky cooling system, the fore-and-aft distance from connector to sealing ring pedestal is less, both simplifies the structure, and also greatly reduces cost.If seal wears, then by regulating the position of sealing clamp on axle, what make sealing clamp continue to keep with seal ring is good fit, the effect of enhanced leaktightness.
