Abstract
The utility model relates to an adjustable built-in mechanical sealing device, comprising a spring positioned between an adjustable positioning sleeve and a movable ring seat. The movable ring seat is provided with a sealing rubber sleeve. A movable ring is provided with a circular boss, and the circular boss of the movable ring is matched with the sealing rubber sleeve in the movable ring seat. The sealing rubber sleeve is provided with a matching segment matched with a pump shaft. The outer part of the matching segment is provided with an enclasping sleeve, and the end surface of the movable ring is provided with a stationary ring matched with the movable ring. The outer part of the stationary ring is provided with the sealing sleeve of the stationary ring. The adjustable positioning sleeve is provided with an axial positioning screw. The utility model has the advantages of simple structure and good sealing performance and is especially suitable for the sealing reform of old-type pumps.
Description
The utility model relates to the seal arrangement in the mechanical field, particularly relates to a kind of machinery that is loaded on, for example the adjustable mechanical seal device of pump components interior.
For preventing in the machinery, especially oil in the pump housing or water leak, normally used Sealing Device has seal ring, sealing gasket and packing etc., these air lockings be difficult for to be adjusted the pressure at sealing position, thus when seal pressure less or wear and tear after, sealability is relatively poor, especially to the sealing at the sealing of highly pressurised liquid or moving parts kinematic pair position difficulty more, this exogenesis air locking generally all is nonadjustable, and maintenance and the adjustment for equipment brings inconvenience like this.
The purpose of this utility model is the poor sealing performance at the sealing components and parts existence of present use, problem such as can not adjust, provide a kind of good seal performance, adjustable interior installation tool seal arrangement, this device is specially adapted in the pump class high-tension apparatus, has also solved old pump repacking problem simultaneously.
The purpose of this utility model realizes by following manner, installation tool seal arrangement includes adjustable setting sleeve in adjustable, spring sealed gum cover, rotating seat, rotating ring, the stationary ring seal rubber sleeve, stationary ring, hold cover tightly, its medi-spring is between adjustable setting sleeve and rotating seat, is provided with a seal rubber sleeve in the rotating seat, rotating ring has a round boss, the round boss of this rotating ring matches with the seal rubber sleeve that is located in the rotating seat, promptly is provided with seal rubber sleeve between rotating seat and the rotating ring round boss, sealer be with match with pump shaft and to the cooperation section of adjustable setting sleeve extension, the outside of this cooperation section is held cover tightly, be mounted with stationary ring with matching on the end face of rotating ring, the stationary ring outside is provided with the stationary ring stuffing box gland, and the axially locating screw is arranged on the adjustable setting sleeve.The surface of contact of rotating ring and stationary ring is provided with annular seal groove.
The best graphite of rotating ring material, static ring material are metal.In use, with adjustable setting sleeve, spring, seal rubber sleeve, rotating seat, stationary ring, stationary ring gum cover and hold cover tightly and be contained in respectively on pump shaft and the pump housing or the Gland according to equipped requirement, its adjustable setting sleeve is fixed on the pump shaft to spring compression and with the axially locating screw by adjustable setting sleeve, when pump shaft rotates, rotating ring, spring and adjustable setting sleeve all rotate thereupon, because stationary ring is to be set on the pump housing (or gland packing), the stationary ring transfixion, stationary ring and rotating ring surface of contact relatively rotate, because this surface of contact cooperates tight, be provided with annular seal groove on the rotating ring again, the pressure that adds upper spring, so can liquid body exudate on the fitting surface, simultaneously since spring and regulate the setting of setting sleeve make and can adjust seal arrangement as required.
The utility model has the advantages that simple in structurely, good seal performance can be adjusted sealed member, is specially adapted to the seal reconstruction of old-fashioned pump, thereby has improved the sealing problem of the old-fashioned pump housing.
Description of drawings is as follows:
Accompanying drawing 1 is a structural representation of the present utility model.
Further describe structure of the present utility model below in conjunction with accompanying drawing.
Now join accompanying drawing 1, adjustable interior installation tool seal arrangement of the present utility model comprises adjustable setting sleeve 1, spring 2, seal rubber sleeve 3, rotating seat 4, rotating ring 5, stationary ring seal rubber sleeve 6, stationary ring 7 is held cover 8 tightly, its medi-spring 2 is between adjustable setting sleeve 1 and rotating seat 4, be provided with a seal rubber sleeve 3 in the rotating seat 4, rotating ring 5 has a round boss, and this round boss matches (as shown in the figure) with seal rubber sleeve 3 in being located at rotating seat 4, seal rubber sleeve 3 has cooperation section that match with pump shaft 10 and that extend to adjustable setting sleeve 1, the outside of this cooperation section is held cover 8 tightly, on the end face of rotating ring 5 be mounted with stationary ring 7 with matching, stationary ring 7 outsides are provided with stationary ring stuffing box gland 6, on the adjustable setting sleeve 1 axially locating screw 9 is arranged, on the surface of contact of rotating ring 5 and stationary ring 7 annular seal groove 11 is arranged.
Claims (2)
1, a kind of adjustable interior installation tool seal arrangement, it is characterized in that it comprises adjustable setting sleeve, spring, seal rubber sleeve, rotating seat, rotating ring, the stationary ring seal rubber sleeve, stationary ring is held cover tightly, its medi-spring is between adjustable setting sleeve and rotating seat, be provided with a seal rubber sleeve in the rotating seat, rotating ring has a round boss, and the round boss of this rotating ring seal rubber sleeve interior with being located at rotating seat matches, be to be provided with seal rubber sleeve between rotating seat and the rotating ring round boss, sealer is with the cooperation section that matches with pump shaft and extend to adjustable setting sleeve, and the outside of this cooperations section is held cover tightly, is mounted with stationary ring with matching on the end face of rotating ring, there is the stationary ring stuffing box gland stationary ring outside, does not have the axially locating screw on the adjustable setting sleeve.
