Description
Technical field
The utility model relates to a kind of being widely used on the petroleum natural gas pipeline, and the valve of block media circulation in the devices such as oil recovery, oil refining, petrochemical industry, chemical industry, chemical fibre, metallurgy, electric power, nuclear power, food and papermaking, specifically is a kind of upper-mounting type ball valve.
Background technique
The main feature of ball valve is compact structure own, and sealing is reliable, and is simple in structure; Easy to maintenance, sealing surface and the sphere closed state of being everlasting is difficult for by the medium erosion; Easy operating and maintenance are applicable to general work media such as water, solvent, acid and rock gas, but also are applicable to the medium that operating conditions is abominable; Like oxygen, hydrogen peroxide, methane and ethene etc., therefore, ball valve has obtained using widely in every profession and trade.When present ball valve breaks down on pipeline and need to repair, need from the pipeline the ball valve dismounting is overhauled ball valve again, attach it on the pipeline after fixing again on, whole process very complicated, time-consuming expensive, be unfavorable for High-efficient Production.Sealing surface and spheroid interface pressure can not be regulated automatically in traditional ball-valve structure, and easy residual precipitated impurities makes ball valve stopped up by impurity, cause valve to open, even occur leaking, and using effect is relatively poor, and very dangerous.Therefore be badly in need of occurring a kind of be convenient to overhaul installation and good sealing effect, be convenient to manipulate and safe and reliable ball valve.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned existing technology, provides a kind of conveniently overhauling to install and good sealing effect, is convenient to that people manipulate and safe and reliable upper-mounting type ball valve, satisfies the demand of safety, High-efficient Production.
The utility model solves the technological scheme that its technical problem adopts: this upper-mounting type ball valve; Comprise valve body, spheroid, be provided with seal ring between valve body and the spheroid, spheroid is connected in the valve body through stem shaft; Be provided with wedge-shaped blocks between seal ring and the valve body; The wedge-shaped blocks outer end has held out against spring seat, is fixed with lid on the valve body of this spring seat top, is supported with pressure spring between lid and the spring seat.Like this, utilize pressure spring holddown spring seat, spring seat evenly is pressed on the wedge-shaped blocks again, and chain effect between lid, pressure spring, spring seat, seals and other component makes that the seal pressure between valve body and the spheroid is able to automatic adjusting.Efficiently solving in traditional ball-valve structure valve body inner sealing surface and spheroid interface pressure can not self-regulating problem, helps seal ring and on valve body, reciprocatingly moves, and makes ball valve be difficult for being stopped up by impurity, and it is more convenient that ball valve is opened and closed, and obturation effect is better.And whole ball valve presents the dress formula, and the dismounting maintenance is very convenient.
Further, have axis hole on the lid, valve rod comprises upper valve rod, lower valve rod, and upper valve rod is located in the axis hole, is provided with the bulge loop platform in the axis hole, and these bulge loop platform bi-side are equipped with sealing gasket.Be convenient to the installation and maintenance of valve rod, spheroid like this.When valve breaks down the needs repairing on pipeline; Will not dismantle from pipeline by whole ball valve, the fixing bolt on the lid of need only dismantling is taken off valve gap and valve rod group component together from valve body; Take out spheroid then and the valve seat combination part repairs or replaces, very easy.
Valve rod comprises upper valve rod, lower valve rod, and the upper valve rod sidewall is provided with one group of pin-and-hole, and each pin-and-hole outer end is equipped with steel ball, is provided with power spring in the pin-and-hole, and this power spring one end is supported in steel ball, and the other end is supported in pin-and-hole the inner.Like this, power spring and steel ball be used the installation that can be convenient to valve rod, spheroid, the setting of power spring simultaneously makes ball valve possess anti-static effect, avoids static sparking firing combustibles matter, guarantees the safety of operation and total system.
Valve rod comprises upper valve rod, lower valve rod, and the valve body bottom is fixed with end cap, is lined with packing ring between end cap and the lower valve rod, and lower valve rod is arranged with O-ring seals outward.Like this, packing ring, O-ring seals make ball valve safer to playing the better seal effect between lower valve rod and valve body, the end cap.
Valve rod comprises upper valve rod, lower valve rod, and the upper valve rod end is provided with handwheel.Handwheel is convenient to the people and is is manually opened and closed ball valve, and is easy to use.Liner has Intermediate gasket between valve body and the lid.Intermediate gasket is provided with the sealing effect that helps improve ball valve.
Be filled with filler between upper valve rod and the lid, this filler is located at bulge loop platform top, and the filler outer end has compressed gland.Filler is graphite-filled material.Graphite packing have an anti-fire action, and its chemical stability is high, rebound elasticity is good, can effective seal action be provided to ball valve.
Pressure spring is a belleville spring.Belleville spring is easy to install and use, and elastic force is big, and support strength is high, good stability, the working life of improving ball valve effectively.
The effect that the utility model is useful is: the utility model rational in infrastructure, compact; Through rational Match setting between a plurality of parts such as valve body, spheroid, valve rod, lid, pressure spring, spring seat and seal ring, realize that the seal pressure between valve body and the spheroid can automatically adjust, effectively solve the difficult maintenance of traditional ball valve, be prone to by problems such as impurity obstruction and sealability instabilities; It is easier that ball valve is safeguarded; It is more convenient to open and close, and obturation effect is better, uses safer.Time saving and energy saving, safe and reliable during the utility model maintenance, sealability is high, and cost is reasonable, is worthy of popularization.
