Description
Technical field
The present invention relates to a kind of ceramic stop valve.
Background technology
Stop valve form in the market is varied, and performance is different, but makes
Existing stop valve structure is simple in, poor sealing performance, and common stop valve has stream when in use
Body directionality, so being check valve, service life is short, not easy-maintaining after damage, generally requires
Integral replacing, use cost is high.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of ceramic stop valve.
The ceramic stop valve of the present invention, including valve body, the inside of the valve body is provided with ceramic-lined
Set, the middle part of ceramic-lined set is provided with ceramic partition wall, and ceramic partition wall is by the inside of ceramic-lined set
Left valve pocket and right valve chamber are separated into, the top of ceramic-lined set is provided with uuper valve chamber, the top of left valve pocket
It is equipped with the top of portion and right valve chamber in flowing hole, flowing hole and is equipped with ceramic valve plug, ceramics
The top of valve plug connects valve rod by straight pin, is connected between the top of valve rod and valve body by screw thread
Connect, the top of valve rod is equipped with bucking ladder, wherein being arranged handwheel positioned at the bucking ladder top in left side.
The ceramic stop valve of the present invention, the valve body is stainless steel, cast steel or cast iron valve body.
The ceramic stop valve of the present invention, the contact position of the valve rod and valve body is close by O-ring
Envelope.
The ceramic stop valve of the present invention, the valve rod is stainless steel valve rod.
Beneficial effects of the present invention are compared with prior art：The ceramic stop valve structure of the present invention
Novelty, a valve is double to be opened, and can open one of ceramic valve plug, with another valve plug control valve door
Unlatching, when after the abrasion blow-by of valve plug another valve plug being used to be switched；Valve
Internal portion uses ceramic-lined set, and valve plug is also using ceramic valve plug, and good seal performance uses the longevity
Life is about twice of traditional stop valve, and each accessory can be carried out changing after damage, and
It is lightweight, install and change all very convenient.

Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention makees further detailed
Description.Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
As shown in Figure 1-2, a kind of ceramic stop valve, including valve body 1, the valve body 1 it is interior
Portion is provided with ceramic-lined set 2, and the middle part of ceramic-lined set 2 is provided with ceramic partition wall 3, ceramics every
The inside of ceramic-lined set 2 is separated into left valve pocket 4 and right valve chamber 5, ceramic-lined set by wall 3
2 top is provided with uuper valve chamber 6, and the top of left valve pocket 4 and the top of right valve chamber 5 are equipped with
Ceramic valve plug 7 is equipped with flowing hole, flowing hole, the top of ceramic valve plug 7 passes through straight pin
8 connection valve rods 9, are connected through a screw thread between the top of valve rod 9 and valve body 1, valve rod 9
Top is equipped with bucking ladder 10, and bucking ladder 10 and valve rod 9 are formed in one structure, its middle position
Handwheel 11 is arranged in the top of bucking ladder 10 in left side.
The ceramic stop valve of the present invention, the valve body 1 is stainless steel, cast steel or cast iron valve body.
The ceramic stop valve of the present invention, the contact position of the valve rod 9 and valve body 1 passes through O shapes
Circle 12 is sealed.
The ceramic stop valve of the present invention, the valve rod 9 is stainless steel valve rod.
The ceramic stop valve of the present invention, will be first with handwheel by one end after installing when specifically used
Valve rod lift standing together with ceramic valve plug, using handwheel by the valve rod rotate counterclockwise of the other end
Ceramic valve plug is opened, fluid enters uuper valve chamber from side valve pocket, then is flowed out from opposite side.When suitable
During hour hands rotation hand wheel, ceramic valve plug declines, until closing ceramic valve plug.When used one section
Between after, when blow-by occurs in the ceramic valve plug at this end, just by the valve rod at this end together with ceramics
Valve plug lifts standing, on the valve rod that handwheel sleeve is lifted before first, is opened using this valve rod
Closing valve, can select one of ceramic valve plug to be used for the unlatching of control valve, and another pottery
Porcelain valve plug is normally opened to be set, using flexible.Therefore, this valve belongs to a valve pair and opened, and service life is
One twice opened.All parts of this valve can be carried out changing after damage, and this valve weight
