Abstract
The utility model relates to a fluid sealing device, particularly a reciprocating mechanical sealing device applied to engineering vehicles and high pressure pump bodies. Through the improvement of a pressing mechanism in the original device, an elastic force storing mechanism, a force transmitting mechanism, a pressing mechanism and the artful connection thereof are arranged. The utility model has the advantages of automatic adjustment of thrust and pressure under working condition, accurate and reliable adjustment and good sealing effect.
Description
The utility model relates to the seal arrangement of convection cell, particularly a kind of reciprocating machine seal arrangement.
The reciprocating machine sealing is a kind of form of mechanical seal.Presently used reciprocating machine seal apparatus is made of the filler, filler cover and the end cap that are contained on the reciprocating shaft basically.Though structure is fairly simple, its disadvantage is can't adjust compensation automatically under the body working state.May wear to when to a certain degree influencing sealing effect as filler, just must shut down, adjust pressure by the artificial turn end cap of experienced skilled worker personnel and could continue the assurance sealing effect.
The purpose of this utility model is by improving the end cap pressure texture, provide a kind of under the body working state, can adjust the reciprocating machine seal arrangement to the pressure of stuffing box packing automatically, having overcome the deficiency that prior art exists.
The technical solution of the utility model includes the reciprocating shaft of work body, is sleeved on axle sleeve, elasticity V-type filler, filler cover, O RunddichtringO on this and the fixedly end cap that is fastenedly connected by clamping bolt and work body.On reciprocating shaft, be set with elasticity and hold force mechanisms, force transmission mechanism and thrust mechanism.The end that elasticity is held force mechanisms is connected with power spare, and its other end is arranged on fixedly in the end cap.Between fixing end cap and reciprocating shaft, be set with successively with elasticity and hold force transmission mechanism that force mechanisms is connected and contact the thrust mechanism that is connected with force transmission mechanism.
It is to constitute by being sleeved on the spring on the reciprocating shaft and the fixed connecting piece at two ends that elasticity is held force mechanisms.
Constitute by the cutting ferrule that protects that is connected swivel nut, jump ring sheet and be equipped with it with the fixed connecting piece of power spare connecting end.The fixed connecting piece of its other end is by being sleeved on reciprocating shaft and fixedly the reciprocal cage plate between the end cap and thereon the spring spare of deciding of dress constitute.
Force transmission mechanism is made of the axial inclined hole of inserting moving part and be equipped with it on thrust mechanism.Insert moving part one end and pass and tighten up and be contained on the reciprocal cage plate, its other end passes the inclined hole that fixing end cap inserts on the thrust mechanism and becomes the contact connection.
Thrust mechanism is made of the screw thread guide sleeve of ratchet and cooperation with it.Ratchet is by the outer ring with axial inclined hole, inner ring, is contained in the steel roll body between the Internal and external cycle and is with the torsion spring of ratchet to constitute.The screw thread guide sleeve is sleeved between reciprocating shaft, axle sleeve and the ratchet inner ring, becomes to be threaded with inner ring.
In the ratchet outer ring and fixedly also be provided with steel ball between the end cap and between screw thread guide sleeve and the elasticity V-type filler.
The utility model has the pressure that can adjust automatically stuffing box packing compared with the prior art under the body working state, adjust accurate, reliable and advantage of good sealing effect.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1: topology view of the present utility model
Fig. 2: the A-A sectional view among Fig. 1
Fig. 3: the B-B sectional view among Fig. 1.
Below in conjunction with embodiment the utility model is further described:
Fig. 1-Fig. 3 shows that the utility model comprises reciprocating shaft 21, axle sleeve 19, elasticity V-type filler 22, filler cover 1, O RunddichtringO 23 with auxiliary hole 20 and the fixedly end cap 9 that by clamping bolt 4 and body 24 be fastenedly connected of suit on it.The fixed connecting piece of spring 12 1 ends is made of the cutting ferrule 15 that protects of the connection swivel nut 13 that is connected with power spare, jump ring sheet 14 and cooperation with it.Jump ring sheet 14 block spring 12 1 ends the termination, be contained in and connect swivel nut 13 and protect between the cutting ferrule 15.The fixed connecting piece of spring 12 the other ends is by being sleeved on reciprocating shaft 21 and the fixing reciprocal cage plate between the end cap 9 10 and tighten up thereon with holes of dress and decide spring spare 11 and constitute.Spring 12 1 ends with decide spring 1 and be connected.Insert moving part 17 and pass reciprocal cage plate 10 and fixing end cap 9, the one end is contained on the reciprocal cage plate 10 by nut 16, and the axial inclined hole that the other end inserts ratchet outer ring 7 becomes contact to connect.The torsion spring 18 of steel roll body 6 and band ratchet is housed, outer ring 7 and fixedly be provided with steel ball 8 between the end cap 9 between the outer ring 7 of ratchet and the inner ring 5.Screw thread guide sleeve 3 is contained between inner ring 5 and reciprocating shaft 21 and the axle sleeve 19, with inner ring 5 for being threaded.
Working mechanism of the present utility model and process are: when reciprocating shaft 21 was in running order, spring 12 was done synchronous to-and-fro motion with the fixed block of power spare connecting end with reciprocating shaft 21, and drove spring 12 and make fore and aft motion, and had assembled certain elasticity.The other end fixed connecting piece of spring 12 exists the reciprocating by a small margin possibility of work, when it also does reciprocating action, just moving part 17 actions are inserted in drive, by inserting the inclined hole on the moving outer ring 7, promptly make Internal and external cycle 5,6 original places of ratchet do turn in the same way to turn power of ratchet.Screw thread guide sleeve 3 turn under this dynamic action is advanced and is pushed elasticity V-type filler 22.The course of action of above-mentioned force transmission mechanism and thrust mechanism is again to determine at the elastic acting force of elasticity V-type filler 22 (being its degree of wear or sealing situation).When elasticity V-type filler 22 was in the excellent sealing state, the pushing force of its elastic acting force and screw thread guide sleeve 3 was in state of equilibrium substantially, and at this moment above-mentioned action does not just take place for force transmission mechanism and thrust mechanism.And when its elasticity V-type filler 22 is bad because of sealing appears in wearing and tearing, its elastic acting force is less than the pushing force of screw thread guide sleeve 3, power transmission machine and thrust mechanism hold in elasticity and begin action under the force mechanisms effect, 3 turns of screw thread guide sleeve are advanced, thereby make pushing force and elastic acting force reach new balance.At this moment elasticity V-type filler 22 is in good sealing state again.
