Abstract
The utility model provides a self-sealing type quick hydraulic joint which comprises a connecting body, a shell sealing ring, an upper shell, a movable valve element pressing spring, a movable valve element, an ejection rod, a piston, a piston sealing ring, a union, a piston reset spring and a lower shell. The connecting body is in threaded connection with the upper shell; the upper shell and the lower shell are connected through the union; a reducing annular platform arranged in the middle of the lower shell is in threaded connection with the lower end of the ejection rod; the piston and the piston reset spring are arranged between the upper end and the annular platform of the lower shell; the movable valve element and the movable valve element pressing spring are arranged between the ejection rod and the connecting body. The self-sealing type quick hydraulic joint has the advantages that quick supply of hydraulic oil can be achieved through quick connection between a hydraulic pipeline and a hydraulic clamp; when the union is dismantled, the movable valve element can be closed quickly and automatically, and the hydraulic oil can be prevented from leaking to cause waste and polluting the construction environment.
Description
Technical field
The invention belongs to a kind of accessory that petroleum production industry production equipment uses, the self seal hydraulic rapid pipe joint that specifically a kind of high-pressure and hydraulic pipeline is connected fast with hydraulic tongs, also can be used for the quick connection of the liquid line such as oil transportation, water delivery in daily life.
Background technique
In the hydraulic system of working machine, diesel engine rotates through gearbox driven gear pump, and the mechanical energy of diesel engine being sent by hydraulic oil changes hydraulic energy into, then passes to each oil hydraulic cylinder and oil hydraulic motor through high pressure line, hydraulic energy is converted to mechanical energy, drive each several part work.Hydraulic tubing tong is exactly according to above-mentioned principle, installs by fast connecting joint, rely on hydraulic oil in hydraulic line mobile come transferring energy, reach the object of oil discharge pipe.Because hydraulic tongs is the attached power tool of workover eration, need often carry out dismounting, what operation field used at present is two ends open and close type hydraulic joints, after repeated disassembled and assembled repeatedly, the each position of hydraulic tongs jointing is easily loosening, under the effect of hydraulic pipe line 8-10Mpa pressure, the phenomenons such as seal ring damage, Self-sealing valve spring failure often occurs, cause hermetic unit leakage of oil or the valve member can not normal switch, need to repair or replace in time.And after the use a period of time of construction in the wild, in hydraulic joint connection sliding outer cover, enter after silt particle, dismounting difficulty, has affected the normal operation of job execution, causes the waste for no reason of hydraulic oil, and pollutes construction environment.
Summary of the invention
The purpose of this utility model is to provide a kind of self seal hydraulic rapid pipe joint, overcomes the defect that above-mentioned prior art exists,
The technical solution of the utility model is achieved in the following ways:
The utility model comprises that connecting body, housing seal circle, upper shell, movable spool press down spring, movable spool, push rod, piston, piston packing, union, piston reset spring and lower shell body, it is characterized in that connecting body is threaded with upper shell, between upper shell and lower shell body, union is connected, the undergauge annular table that lower shell body middle part arranges is threaded with push rod underpart, between the upper end of lower shell body and annular table, be provided with a piston and a piston reset spring, between push rod and connecting body, be provided with a movable spool and a movable spool presses down spring.
Connecting body is made as cylindrical, and upper and lower is provided with male thread, and lower upper periphery is provided with annular boss.
Upper shell is made as cylindrical, and top is provided with box thread, and bottom is provided with male thread, is provided with the valve core case of the upper side band one fixed inclination lower side band straight angle in lower top week.
Movable spool is made as hat, and week is provided with the sealing surface being sealed and matched with valve core case below.
Piston is made as cylindrical shape, and upper end periphery is provided with annular boss, and lower, outer perimeter is provided with the seal ring with lower shell body sealing.
Lower shell body is made as cylindrical shape, and middle and upper part periphery is provided with union snap ring, is provided with convex table type spring seat in middle part week.
Push rod is made as cylindrical shape, and upper top is provided with sealing clamp, and upper periphery is provided with the seal ring with piston seal, and middle part periphery is provided with liquid-through hole, and bottom is provided with male thread, and the diameter of sealing clamp is greater than the interior warp of piston.
The utility model has the advantages that: be connected with the quick of hydraulic tongs by hydraulic line pipeline, realize the quick supply of hydraulic oil, in the time of dismounting union, movable spool can be closed again fast voluntarily, prevent that hydraulic fluid leak from causing waste and polluting construction environment.
Accompanying drawing explanation
Accompanying drawing-structural representation of the present utility model;
In figure, the movable spool of 1-connecting body 2-housing seal 3-upper shell 4-presses down the movable spool 6-of spring 5-push rod 7-piston 8-piston packing 9-union 10-piston reset spring 11-lower shell body.
Embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises connecting body 1, housing seal circle 2, upper shell 3, movable spool presses down spring 4, movable spool 5, push rod 6, piston 7, piston packing 8, union 9, piston reset spring 10 and lower shell body 11, it is characterized in that connecting body is threaded with upper shell, between upper shell and lower shell body, union is connected, the undergauge annular table that lower shell body middle part arranges is threaded with push rod underpart, between the upper end of lower shell body and annular table, be provided with a piston and a piston reset spring, between push rod and connecting body, be provided with a movable spool and a movable spool presses down spring.
In the time of application the utility model, lower shell body is welded on hydraulic power pipeline, link by union and upper shell, upper shell upper end is connected with connecting body 1 after loading onto housing seal circle 2, the pipeline of connecting body and hydraulic tongs connects, connect push rod up under the effect of union, back down movable spool, push rod loses with the sealing of piston and exposes liquid-through hole, hydraulic oil connecting port is opened, and hydraulic tongs is started working.When dismounting is when union, movable spool presses down at movable spool under the effect of spring and closes with valve seat, piston under the effect of piston reset spring with the sealing gland sealing of push rod.In the time that union is dismantled, two ends are all in sealing state, and hydraulic oil can not leak, free from environmental pollution.
