Utility model content
The main purpose of the utility model is to provide a kind of anti abrasive high-pressure cylinder of high sealing, can effectively solve to carry on the back Existing high-pressure cylinder high-pressure tightness is poor in scape technology, sealing element displacement offset, serious wear, the high problem of cost.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of anti abrasive high-pressure cylinder of high sealing, including cylinder barrel, cylinder barrel outside set radiating sleeve, are clear opening in cylinder barrel, The inner wall of cylinder barrel one end sets interior concave station, and sealing element is set on interior concave station, and sealing element includes retaining ring, plastic washer, slip ring one, metal Washer and slip ring two set piston in cylinder barrel, and piston one end sets step, and guide ring is set on step, and guide ring two sides set sealing copper Washer, sealing copper gasket inside successively set cushion seals circle, O-ring one, washer, and the top of piston sets locking nut, locking screw Butterfly spring is set between female and washer.
Preferably, inner wall of cylinder sets cylinder sleeve, and cylinder sleeve is high molecular polymer, can protection cylinder barrel inner wall, while replace just It is prompt.
Preferably, groove being set on the inside of cylinder barrel, retaining ring is located in groove, and retaining ring limits the position between each seal elements, Connect each sealing element closely.
Preferably, retaining ring, plastic washer, slip ring one, metal washer and two inner ring of slip ring on the same line, in work When plug moves back and forth, active force simultaneously is kept, the airtightness of high pressure cylinder body is increased, reduces abrasion.
Preferably, cylinder barrel outer ring is equipped with protrusion circle, and radiating sleeve is close to protrusion circle, and protrusion circle two sides set O-ring two, outside cylinder barrel The protrusion circle of circle is used to limit the position of radiating sleeve, and O-ring two closely connect with radiating sleeve, makes closed between radiating sleeve and cylinder barrel Connection, the heat that cylinder barrel generates can concentrate discharge, while increase the frictional force between radiating sleeve and cylinder barrel, make radiating sleeve position It is not easy deviation.
Preferably, radiating sleeve nut is set on radiating sleeve, radiating sleeve nut and radiating sleeve weld, and radiating sleeve top inner wall sets O Type circle three, the external cold scarce element of heat dissipation nut connection, the heat for generating cylinder body exclude in time, and cylinder body is prevented to be in the condition of high temperature Piston motion increasing is worn caused by cylinder body.
Compared with traditional technology, the beneficial effect that the utility model generates is: passing through each sealing member of high-pressure cylinder inner wall Part closely connects, while being combined using rigid seal with soft rubber, interaction, and it is inclined to effectively prevent sealing element displacement It moves, improves sealing performance;Sealing element on piston reduces high-pressure cylinder inner wall abrasion, the sealing element reduction pair on high-pressure cylinder The dry abrasion of piston;Abrasion is mutually reduced between piston and high-pressure cylinder, reduces maintenance cost.
