Background technology
Often use tank body and pipeline such as various conveyance conduit, hot channel and chemical pipeline etc. need often to clean, to guarantee the unimpeded of above-mentioned pipeline, avoid stopping up.Traditional cleaning method is that pipeline or tank body are placed in the cleaning fluid, the dirt that is attached to above-mentioned pipeline or inner tank wall is come off automatically be dissolved in the chemical, thereby reach the purpose of pipe blow-through.After cleaning finishes ducted cleaning fluid is emitted outside pipeline or the tank body.This traditional cleaning method is polluted bigger, and the time of required cleaning is long, and the cost of cleaning is high and not good to the cleaning performance of pipeline or tank body.
At present, the method for another kind of pipe blow-through on the market or tank body is to utilize cleaning valve to clean.This cleaning valve is mainly the pressure wash valve, and the main high-pressure cleaning liquid that utilizes spray to extrude washes away the dirt that is attached on the inner-walls of duct, and there is potential safety hazard in this cleaning valve, and can not the Fouling Cleaning of corner or spot as yet untouched by a clean-up campaign is clean, and it is high to clean cost.And the rotating wash bowl of another kind of cleaning valve utilization rotation carries out the dirt on inner tank wall or the pipe blow-through wall, and this cleaning way need be with stretching in the rotating wash bowl in pipeline or the tank body, and rotating wash bowl rotates the inwall of purge tank body or pipeline under the pressure effect of cleaning fluid.But cross when dark when the inwall of pipeline or tank body, this cleaning valve can not freely stretch the dirt that is positioned at these positions is cleaned, very inconvenience.
Summary of the invention
The objective of the invention is to: the deficiency for to prior art the invention provides a kind of convenience for washing, the telescopic cleaning valve that cleaning performance is good.
In order to realize above-mentioned purpose, the technical scheme below the present invention has adopted: a kind of telescopic cleaning valve comprises valve body and the rotating wash bowl that is arranged in the valve body; One side of valve body is provided with the filter washing water inlet, and described valve body top is provided with actuator, and described actuator comprises executive system and support; Support and valve body are equipped with, and the cooperation place sealing is provided with, and described rotating wash bowl top is provided with valve rod; One end and the rotating wash bowl of valve rod are fixed, and rotating wash bowl valve rod relatively rotates, and the other end of valve rod extends through support and is fixed on the actuator; Valve rod can be done stretching motion under actuator driven, described valve body below is provided with a cavity volume, supplies rotating wash bowl to lay.
As preferably: described valve body below is provided with conduit, catheter interior hollow, and the conduit bottom exports for rotating wash bowl; Rotating wash bowl is provided with the obstruction piece away from an end of valve rod; When valve rod is in when shrinking fully, stop up piece and export to become to be sealed and matched with the interior rotating wash bowl of conduit, form above-mentioned cavity; At this moment, cavity is a closed cavity.After adopting above-mentioned preferred version; When cleaning valve does not use, can the flexible withdrawal of rotating wash bowl through valve rod be placed in the cavity, avoid rotating wash bowl to be destroyed or pollute; And obstruction piece and being sealed and matched of rotating wash bowl have further been protected rotating wash bowl, and the protection effect is better.
As preferably: described rotating wash bowl outlet is horn-like opening, and big mouthful outwardly, the form fit setting that the shape of described obstruction piece and rotating wash bowl export.After adopting above-mentioned preferred version, when rising under the driving of valve rod at actuator, the rotating wash bowl outlet of rotating wash bowl below is horn-like opening, can make and stop up fast easier snapping in, and goes out interruption-forming with rotating wash bowl and is sealed and matched.
As preferably: described rotating wash bowl and valve rod cooperation place are provided with whirligig, the setting that is sealed and matched of whirligig and valve body and conduit, and described whirligig is provided with the cleaning fluid passage, cleaning fluid import of cleaning fluid channel connection and rotating wash bowl.After adopting above-mentioned preferred version, cleaning fluid gets into rotating wash bowl through the cleaning fluid passage rotates rotating wash bowl under the driving of the cleaning fluid of high pressure, optimized the structure of cleaning valve, makes the structure of cleaning valve more compact.
As preferably: described whirligig comprises and is set in the outer installing rack of valve rod; Described rotating wash bowl comprises bar portion and bulb, and bar portion is provided with groove away from the outer wall of a side in bulb, is provided with ball in the groove; Be provided with fixed cover outside the bar portion, bar portion will be fixedly connected with installing rack through fixed cover.After adopting above-mentioned preferred version, reduced and cleaned the friction between valve stem and mounting bracket and the fixed cover, reduced and invade the wearing and tearing of cleaning between valve stem and mounting bracket and the fixed cover, the service life of having improved cleaning valve.
As preferably: the below of described support is provided with boss, and described valve body top is provided with pressing plate with the cooperation place of support, and pressing plate is set in outside the valve rod, and is provided with the stem shaft sealing.After adopting above-mentioned preferred version, structure is more compact, and sealing effectiveness is better.
As preferably: described valve rod is provided with guide pin bushing, and guide pin bushing is arranged on the boss of support.After adopting above-mentioned preferred version, when elongating or shortening under the driving of valve rod at actuator, guide pin bushing plays guiding and fixation, avoids valve rod to de-orbit, and it is flexible to make valve rod can more stably drive rotating wash bowl.
As preferably: the cooperation place of described support and valve body is provided with clip, and support is fixedly connected through clip with valve body, and the cooperation place of described conduit and valve body is provided with clip, and conduit is fixedly connected through clip with valve body.After adopting above-mentioned preferred version, cooperation and fixed effect between each parts have been improved.
As preferably: described conduit away from actuator a side outer wall be provided with flange, flange and conduit carry out secure fit through a clip.After adopting above-mentioned further being provided with, be convenient to dismounting, installation, maintenance and the inspection of the telescopic cleaning valve of the present invention, more convenient practicality.
Telescopic cleaning valve of the present invention is mainly used in tank body and transfer pipeline is cleaned; Under normal state; Conduit is closed closed cavity with stopping up the formed cavity of piece; When need be when being cleaned the cleaning of equipment, rotating wash bowl stretches out conduit under the effect of actuator, equipment is cleaned.
Telescopic cleaning valve of the present invention can freely stretch, and after accomplishing cleaning, rotating wash bowl is withdrawn under the effect of valve rod in the cavity; Avoid being damaged or polluting, in addition, when cleaning; Rotating wash bowl can be released by valve rod under the driving at actuator, rotation under the effect of cleaning fluid pressure simultaneously; Clean reposefully and be cleaned equipment, guaranteeing does not have the corner or spot as yet untouched by a clean-up campaign.
