Abstract
A kind of novel Unloading ball valve of the utility model relates to valve technology field, comprise spheroid, described spheroid is placed among right valve barrel and left valve barrel, valve seat is provided with between described spheroid and right valve barrel, left valve barrel, it is characterized in that: described valve seat is the high strength O type circle of hollow, O type circle is provided with little steel pipe, described spheroid is connected with valve rod, described valve rod is connected with the pneumatic head of the topmost part by connecting sleeve, support, pneumatic head is connected with adapter, described adapter is connected with little steel pipe, and described adapter is provided with filter; The valve seat of the utility model product is connected with adapter, and adapter is connected with pneumatic head, and in conjunction with the switch of pneumatic head, absorb the gas in O type circle when opening, O type circle reduces, and sealing pair is separated.Pass into O type circle air when pass, O type circle swells, and sealing pair is tightly close together.Thisly controlled to play self-sealing effect by pneumatic head, the moment plays good sealing and unloads ash effect, more safe and reliable.
Description
Technical field
The utility model belongs to valve technology field, specifically a kind of novel ash discharging stop valve.
Background technique
Ball valve (ball valve should be stop valve in extra large work and ship domain), be defined as in standard GB/T21465-2008 " valve term ": open-shut device (spheroid) is driven by valve rod, and around the valve that square work ball valve rotates as axis.Utilize the regulating and control that also can be used for fluid, wherein firmly seal between V-type ball valve its V-type ball core and metal seat valve of pile-up welding hard alloy and there is very strong shearing force, be specially adapted to the medium such as fibre-bearing, a small solid material.And multi-pass ball valve not only can the interflow of control media, shunting and the switching that flows to flexibly on pipeline, also can close arbitrary passage simultaneously and two other passage is connected.This class valve generally should level be installed in the duct.Ball valve is classified: pneumatic ball valve, electric ball valve, manual ball valve.
But ball valve of the prior art, operation is too complicated, can't realize being changed voluntarily by O type circle producing sealing and opening.Therefore, need technical progress, structural improvement, make the automaticity of ball valve higher.
Model utility content
The purpose of this utility model is, provides a kind of novel Unloading ball valve, to realize the Unloading ball valve of self-sealing.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: a kind of novel Unloading ball valve, comprise spheroid, described spheroid is placed among right valve barrel and left valve barrel, valve seat is provided with between described spheroid and right valve barrel, left valve barrel, it is characterized in that: described valve seat is the high strength O type circle of hollow, O type circle is provided with little steel pipe, described spheroid is connected with valve rod, described valve rod is connected with the pneumatic head of the topmost part by connecting sleeve, support, pneumatic head is connected with adapter, and described adapter is connected with little steel pipe.
Described adapter is provided with filter.
Steel ball and spring is provided with between described valve rod and right valve barrel.
Described right valve barrel is fastenedly connected by stud, nut and left valve barrel and is integrated.
By packing seal between described valve rod and right valve barrel, and be connected with right valve barrel with hex head bolt by hold-down grid.
Described valve rod is connected by square toes with between connecting sleeve, and described support bottom is connected with right valve barrel by hex head bolt, and described frame upper is connected with pneumatic head by hex head bolt.
Compared with prior art, the beneficial effects of the utility model are: the valve seat of the utility model product is a kind of high strength O type circle of hollow, little Steel penstocks and connectors on O type circle is connected, adapter is connected with pneumatic head, in conjunction with the switch of pneumatic head, absorb the gas in O type circle when opening, O type circle reduces, and sealing pair is separated.Pass into O type circle air when pass, O type circle swells, and sealing pair is tightly close together.Thisly controlled to play self-sealing effect by pneumatic head, the moment plays good sealing and unloads ash effect.Better than common Unloading ball valve sealability, more safe and reliable.
