Abstract
The utility model discloses a rotary lid type wear resistant spray nozzle, comprising a metal outer tube (4), a ceramics abrasion-proof inner core (3) and a baffle ring (5). The ceramics abrasion-proof inner core (3) which is arranged in the metal outer tube (4) and the baffle ring (5) is fixed to one end of the metal outer tube (4). The other end of the metal outer tube (4) is provided with a rotary cover (1) which is actively connected with the metal outer tube (4). The structure of the utility model can make the ceramics abrasion-proof inner core fastened in the metal jacket without any loss through the adhesion of the ceramic binder and the banding of the metal rotary cover after the metal outer tube is welded with other metal structural members. So broken ceramics abrasion-proof inner core by being squeezing or rimal ceramics abrasion-proof inner core of being squeezing caused by the residual stress due to welding can be avoided. The abrasion resistance of the composite spray nozzle can be protected and the practicability of the ceramic spray nozzle can be enhanced considerably. At the same time, when the ceramics abrasion-proof inner core is damaged, the ceramics abrasion-proof inner core can be reused after detaching the rotary cover to replace the damaged ceramics abrasion-proof inner core.As a result, the use-cost can be reduced.
Description
Affiliated technical field
The utility model belongs to the improvement of wear-resisting nozzle technology, relates generally to the wear-resisting nozzle of a kind of cap-rotating type.
Background technology
The Ceramic Composite nozzle is high temperature resistant, high pressure resistant product, be widely used in petrochemical industry, it mainly is made of metal jacket pipe, earthenware and baffle ring, earthenware is positioned at outer tube, itself and outer sleeve inner wall bonding are fixed, and baffle ring is two up and down, fixes with the entrance point and the port of export of outer tube respectively, be used for fixing earthenware, nozzle becomes a complex.Wear-resisting nozzle re-use in use outer tube need with other hardware welding, when the wear resistant short tube diameter is big, very easily occur causing wear-resisting nozzle anti-wear performance seriously to weaken because of the metal-coating welding residual stress squeezes broken or squeeze crack ceramic wear-resisting inner core.Simultaneously, because it is whole the use, when the ceramic wear-resisting inner core damages, need to cause use cost higher nozzle-integrated replacing.
Summary of the invention
The purpose of this utility model provides the wear-resisting nozzle of a kind of cap-rotating type, can avoid welding residual stress to squeeze broken or squeeze crack ceramic wear-resisting inner core, the detachable simultaneously ceramic wear-resisting inner core of changing.
The purpose of this utility model can adopt following technical scheme to realize: it comprises metal jacket pipe, ceramic wear-resisting inner core and baffle ring, the ceramic wear-resisting inner core is positioned at metal jacket pipe, baffle ring is fixed on an end of metal jacket pipe, at the other end one spiral cover is set, spiral cover and metal jacket pipe flexibly connect
The pipe outer wall of metal jacket pipe and spiral cover junction is provided with fixture block, and the bottom of spiral cover is connected to the fixture block bottom.
Spiral cover and metal jacket pipe are between the two to be threaded.
After said structure of the present utility model can make metal jacket pipe and the welding of other hardware, again by ceramic binder bonding and and the banding of metal spiral cover, be fixed in the metal-coating the ceramic wear-resisting inner core is harmless, avoided welding residual stress to squeeze broken or squeeze crack ceramic wear-resisting inner core, the anti-wear performance of having saved the Ceramic Composite nozzle from damage is strengthened the practicality of ceramic nozzle greatly.Simultaneously, when the ceramic wear-resisting inner core damaged, desirable screwed lid was changed the ceramic wear-resisting inner core that damages can reuse, thereby has reduced use cost.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure: 1, spiral cover, 2, fixture block, 3, the ceramic wear-resisting inner core, 4, metal jacket pipe, 5, baffle ring.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1: the utility model comprises metal jacket pipe 4, ceramic wear-resisting inner core 3 and baffle ring 5, ceramic wear-resisting inner core 3 is positioned at metal jacket pipe 4, baffle ring 5 is fixed on an end of metal jacket pipe 4, at the other end one spiral cover 1 is set, the outer tube that links to each other with spiral cover 1 is provided with fixture block 2, and the bottom of spiral cover 1 is stuck in the bottom of fixture block 2.In addition, also available being threaded between spiral cover 1 and the outer tube 4.
During use, with metal jacket pipe 4 and other hardware welding, ceramic wear-resisting inner core 3 is installed then earlier.When being installed, ceramic wear-resisting inner core 3 earlier ceramic binder is applied in the internal thread of metal-coating 4 and the outer surface of ceramic wear-resisting inner core 3, then ceramic wear-resisting inner core 3 is put into metal-coating 4, again metal spiral cover 1 is cooperated banding with fixture block 2, finish the harmless compound of wear-resisting nozzle.When indivedual wear-resisting nozzle need is changed in maintenance, can screw off metal spiral cover 1 by fixture block 2, remove the ceramic wear-resisting inner core 3 of damage after, new ceramic wear-resisting inner core (1) is installed again.The utility model adopts dismountable bonding and spiral cover compound mode, has avoided the infringement of wear-resisting nozzle in installation process, and the practicality of ceramic nozzle is strengthened greatly.
