Abstract
The utility model provides a hydrolock pipe end packing seal device, includes the pipe end lid of packing seal device, intake pipe, its characterized in that: still be provided with one by outer barrel, go up the water seal structure that gland, rubber seal are formed, outer cylinder bottom's ring flange step ring lower surface laminating is covered on the surface at the pipe end of intake pipe, a plurality of bolt passes to twist behind the ring flange to close to fix implements sealing connection on the nut that the surface corresponds the setting is covered to the pipe end, the enterprising mouth of a river of outer barrel and water source pipe tube coupling, delivery port and outlet pipe tube coupling, going up the gland and being the ring disc, gland medium pore inner wall is equipped with the ring channel, and rubber seal registrates in the ring channel, going up the gland medium pore and emboliaing the piston rod, a plurality of bolt passes walking of on gland equipartition and twists the fixed connection who closes in the screw blind hole that outer barrel upper surface corresponds in the implementation gland barrel outside and behind the hole. The packing seal device is peripheral to make packing pad lubrication, water -cooling with establishing the hydroecium, sealed reliable, ensures the long -time operation of device.
Description
technical field:
The utility model relates to the sealing of ammonia synthesizing industry hydraulic valve system, particularly a kind of water-sealed type pipe end stuffing seal.
background technique:
Ammonia synthesizing industry gas making operation wash vapour tower suction tude because of dust loading in gas large, impact is produced, and often need the fouling of stopping on cleaning tube wall, impact is produced.Adopt after automatic ash removing device, can be implemented in when not stopping, the fouling on Automatic clearance tube wall.Automatic ash removing device is made up of oil hydraulic cylinder, piston rod, stuffing seal, round scraper.Namely in the pipe end-cap of suction tude, a central hole is offered, central hole is welded and fixed a stuffing seal, piston rod fixes a round scraper through its front end after stuffing seal central hole, pipe end-cap central hole, drives piston rod, round scraper to advance in suction tude inwall scrape dirt by oil hydraulic cylinder.Existing stuffing seal is made up of filler seat, packing filling, Gland.Filler seat is mount shell-like, Gland is Step Shaft shell-like, after packing filling being filled in the annular space between step cover for seat and piston rod, Gland is inserted in by its compacting above packing filling again, with bolt, the flange plate of Gland is locked in filler seat upper surface simultaneously.
The sealing principle of packing filling depends primarily on labyrinth effect and bearing effect.Labyrinth effect: piston rod, in the out-of-flatness very of microcosmic lower surface, can only partly be fitted with packing, and part does not contact, so there is small gap between packing and piston rod, as labyrinth, pressure medium repeatedly by throttling, thus reaches the effect of sealing in gap.Bearing effect: laminating, the friction of packing filling and piston rod surface are similar to sliding piston bar and hold, admittedly enough liquid should be had to lubricate, avoid the excessive wear of packing and piston rod, to ensure to be sealed with certain life-span.If adopt packing_seal merely, because the temperature of piston rod and packing dry friction is high, can packing be dried, the gap of packing and piston rod is increased and affects the sealing of packing, destroy liquid film and make packing lose lubrication.
summary of the invention:
The purpose of this utility model is to overcome above-mentioned defect, provides a kind of water-sealed type pipe end stuffing seal.
Scheme of the present utility model is: the pipe end-cap comprising stuffing seal, suction tude, it is characterized in that: be also provided with a sealing structure for water be made up of outer cylinder body, upper press cover, rubber seal, the big up and small down step ring-type of flange plate of outer cylinder body lower end, flange plate step ring lower surface is fitted on the pipe end-cap upper surface of suction tude, and several bolts nut that pipe end-cap upper surface correspondence arranges implement flange plate and pipe end-cap is tightly connected through screwing up after flange plate to be fixed on; Outer cylinder body is provided with water intake, water outlet, and water intake is connected with water source tube pipeline, and water outlet is connected with outlet pipe pipeline; Upper press cover is annulus plate-like, gland central hole inwall is provided with circular groove, rubber seal is linked in described circular groove, upper press cover central hole is inserted in piston rod, several bolts through on upper press cover uniform walk hole after screw up in the tapped blind hole that outer cylinder body upper surface is corresponding, to implement being fixedly connected with of upper press cover and outer cylinder body.
The utility model has the advantage of: stuffing seal periphery adds hydroecium, make packing filling lubrication, water-cooled, sealing is reliable, simple to operate, guarantees the long-play of device.
accompanying drawing illustrates:
Fig. 1 is prior art structural representation.
Fig. 2 is the utility model structural representation.
embodiment:
The utility model comprises the pipe end-cap 11 of stuffing seal, suction tude 10, it is characterized in that: be also provided with a sealing structure for water be made up of outer cylinder body 8, upper press cover 1, rubber seal 2, the big up and small down step ring-type of flange plate of outer cylinder body 8 lower end, flange plate step ring lower surface is fitted on pipe end-cap 11 upper surface of suction tude, and several bolts nut that pipe end-cap 11 upper surface correspondence arranges implement flange plate and pipe end-cap 11 is tightly connected through screwing up after flange plate to be fixed on; Outer cylinder body 8 is provided with water intake 5, water outlet 3, and water intake 5 is connected with water source tube pipeline, and water outlet 3 is connected with outlet pipe pipeline; Upper press cover 1 is in annulus plate-like, gland central hole inwall is provided with circular groove, rubber seal 2 is linked in described circular groove, upper press cover 1 central hole is inserted in piston rod 12, several bolts through on upper press cover 1 uniform walk hole after screw up in the tapped blind hole that outer cylinder body 8 upper surface is corresponding, to implement being fixedly connected with of upper press cover 1 and outer cylinder body 8.
The stuffing seal periphery be made up of filler seat 9, packing filling 7, Gland 6 adds hydroecium 4.Water intake 5 can add water at any time and to be discharged by water outlet, and the inner chamber hydroecium 4 surrounded to outer cylinder body 8 changes water for cooling.
Flange plate laminating pipe end-cap 11 implements bottom water-stop to water seal outer cylinder body 8, and upper press cover 1, rubber seal 2 implement upper water sealing to outer cylinder body 8.
