Abstract
Provided is a floating device of a mud plunger pump one-way valve. A valve cover is installed on a valve body, a valve rod is fixed on the valve cover, a valve plate body is arranged outside the valve rod, a pre-pressing spring is arranged outside the valve plate body, and a floating valve core is arranged under the valve plate body and connected with the valve plate body through a floating bolt. An elastic body is arranged in the floating valve core, a seal ring is arranged under the floating valve core, a locking plate is arranged under the seal ring, and a static valve sleeve is arranged between the seal ring and the valve body. The valve plate body and a floating body are opened and closed in the valve body in a reciprocating mode. When heavy-load downward closing is performed, the floating valve core and the seal ring are firstly in contact with the static valve sleeve, a flowing channel is closed to enable force loaded on the valve plate body to basically fade away due to loss of differential pressure, impact force is greatly decreased, enough buffer is provided for the seal ring through the elastic body in the floating valve core, and the service life is prolonged greatly.
Description
Technical field
The utility model relates to a kind of mud plunger pump, refers in particular to a kind of floating installation of mud plunger pump one-way valve.
Background technique
At present, the one-way valve of mud plunger pump is all that pressured official post valve block directly overlaps and closes both at home and abroad, and in the time of can't realizing opening, distance be large, medium is little by resistance, while closing, distance is little, leaks little purpose.Because plunger pump operates in high pressure conditions basically, be carried in impact force on valve plate and be the poor of the volume pressure of clack box and leakage flow, the particulate matter that certain content is arranged in the powerful impact force the when valve plate in the valve body hyperbaric chamber opens and closes at a high speed and medium, cause the sealing gasket of valve plate no matter to make flat, cone, ball, all be unable to undergo to impact, very quick-wearing lost efficacy.By the time find that one-way valve leaks, while going to change sealing gasket, fallback for a long time, wasted the energy and the easily damaged parts of a large amount of preciousnesses.
Summary of the invention
It is low that the purpose of this utility model is to solve the operational efficiency that has the existence of mud plunger pump now, and frequent shutdown is changed the major defect problem of Sealing, a kind of floating installation of mud plunger pump one-way valve is provided, this floating installation compact structure, upwards float during unlatching to increase and open apart from reducing medium by resistance, float downwards while closing, close in advance, reduce to leak and stable valve body pressure chamber, realize that valve plate is not hit basically; Greatly improve reliability and the operational efficiency of equipment, saved the valuable energy and easily damaged parts.
For achieving the above object, the solution that the utility model is taked is: a kind of floating installation of mud plunger pump one-way valve, a valve gap is housed on valve body, fix a valve rod on valve gap, valve rod has a valve plate body outward, valve plate is external has one to give pressing spring, a floating plug is arranged under the valve plate body, floating plug is connected with the valve plate body by a unsteady bolt, an elastomer is arranged in floating plug, a seal ring is arranged under floating plug, a latch is arranged under seal ring, a quiet valve pocket is arranged between seal ring and valve body.
Valve plate body and float be back and forth open and close in valve body, when heavy duty is closed downwards, floating plug takes the lead in contacting with quiet valve pocket with seal ring, runner is closed, the power that is carried on the valve plate body is disappeared substantially because losing pressure reduction, and impact force reduces greatly, and seal ring gives enough bufferings by the elastomer in floating plug, greatly extended working life, with operational efficiency.
