Abstract
The ball valve comprises a valve cover, a valve body, a valve seat, a ball body, a valve rod and a wrench. The valve cover is connected with the valve body, and a sealing gasket is arranged at the contact of the valve cover and the valve body; the valve seat is positioned on the periphery of a cavity in the valve body; the ball body is positioned in the valve body and is adjacent to the valve seat; an elongated slot is formed in the upper part of the ball body; the valve rod penetrates through the valve body, and the bottom end of the valve rod is placed in the elongated slot; the valve rod is fixed with the ball body through a steel ball and a spring; and the upper end of the valve rod and the wrench are tightly connected together through a positioning plate, a retainer ring and a nut. The ball valve has the benefits that through the improvement design, the ball valve is convenient to assemble and simple to maintain; through additionally arranging the spring and the steel ball, the valve rod is more stably connected with the ball body; and through designing the longer wrench, opening/closing the valve is more labor-saving.
Description
Technical field
The utility model relates to valve class mechanical device, is specially a kind of ball valve.
Background technique
In infrastructure, can utilize the pipeline fed sheet of a media usually,, use ball valve can guarantee best operating conditions and safety of environment as controlling mechanism because pressure or temperature variation need be regulated pipeline.
Common ball valve comprises critical pieces such as valve body, valve gap, valve seat, spheroid, valve rod and spanner; Rotation through the control spheroid realizes that the unlatching and the closure of valve, spheroid are installed in the cavity of valve body central authorities, and is pressed on the valve seat tightly; Guarantee the sealing of valve with this; But bring a lot of shortcomings like this, as: after ball valve is fitted into valve body, be difficult for taking out, maintenance is difficulty also.
The model utility content
The technical problem that the utility model solved is to provide a kind of ball valve, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technological scheme to realize:
A kind of ball valve; Comprise valve gap, valve body, valve seat, spheroid, valve rod and spanner, said valve gap links to each other with valve body and in the contacting point gasket seal is set, and said valve seat is positioned at around the cavity of valve body; Said spheroid is positioned at valve body and near said valve seat; Said spheroid top has an elongate slots, and said valve rod runs through said valve body, and the bottom is placed in the said elongate slots; Said valve rod and spheroid are fixed through steel ball, spring, and said valve rod upper end closely links together through positioning plate, back-up ring and nut with said spanner.
In the utility model, said valve rod and valve body joint are provided with thrust washer.Said nut below is equipped with belleville spring, gland and filler successively.The end of said spanner also is equipped with a spanner cover.
Beneficial effect
The utility model makes ball valve easy to assembly through improving design, and is easy to maintenance; Through adding spring and steel ball, make valve rod more firm with being connected of spheroid; The spanner that design is long makes when opening closure valve more laborsaving.
Description of drawings
