Description
Technical field
It the utility model is related to the slurry valve technical field on alumina producing pipeline, more specifically a kind of antiscour
The valve body of slurry valve.
Background technology
In recent years, aluminum oxide industry in China's is able to fast development with the development of national economy, this industry, it has also become complete
Ball largest production and country of consumption.In order to improve production capacity, some producers are by will increase the side of the production flow line flow velocity of former aluminum oxide
Formula improves production capacity.But under the fast operating mode of the slurry threshold velocity of one of corollary equipment on the production flow line of former aluminum oxide, more
Add easily impaired, short life.
In the prior art the pulp stock valve on alumina producing pipeline as shown in Fig. 2 including lower valve body 15, upper valve body 14 and
Flap 4 and valve rod composition in valve body.Upper and lower valve body is fastened by bolts to form valve body, and valve seat 2 is accompanied between upper and lower valve body.
Being provided with slurry inlet passage 11 in lower valve body 15, upper valve body 14 is interior to be provided with slurry outlet passage 12 and flap active tunnel 13, and three
Individual passage is connected and Y-shaped.From slurry inlet passage 11 to slurry outlet passage 12, slurry passes through in passage sectional area by
Big diminish changes from small to big and the area of overflowing end face is less than the 4/9 of access port sectional area again, mitigates slurry in valve by throttling
To the pressure of flap 4 when door opens and closes.
But after valve is opened, under the operating mode that flow rate of slurry improves, pressure increase in valve body, in the company of upper and lower valve body
Easily occur leakage point between junction, influence valve tightness；And due to throttling action, the flow velocity of flap and valve base chamber is very
Greatly, fluid is by producing larger pressure drop after flap, flap, valve seat and valve body can because the high speed of fluid is washed away and it is frayed plus
It is acute；Especially between flap active tunnel and slurry outlet passage and due to there are sharp corner angle more in the tube wall relative with valve seat
Add easily, damage thinning because of washing away.Due to the presence of drawbacks described above, cause under the fast operating mode of slurry flow rate, pulp stock valve
Valve body easily be damaged, short life.
Utility model content
Technical problem to be solved in the utility model is the defects of overcoming above-mentioned prior art to exist, there is provided a kind of anti-impact
The valve body of brush slurry valve, wear-resistant, service life length.
To achieve the above object, the utility model is achieved by the following technical programs：A kind of antiscour slurry valve
Valve body, including the body with slurry inlet passage, slurry outlet passage and flap active tunnel, it is characterised in that：Described
Body by integral forming is set, and is provided with valve seat in body and valve seat and body are affixed；In slurry outlet passage and flap active tunnel phase
Ribs is provided between tube wall even；The port of the slurry inlet of the slurry outlet passage is isometrical；It is described in flap standard-sized sheet
The area of minimum overflowing end face is more than the slurry inlet access port sectional area between slurry inlet passage and slurry outlet
9/16。
Using above-mentioned technical proposal, one, valve body shaping avoid lower valve body between sealing surface it is fast in slurry flow rate
Operating mode under easily there is the problem of leakage point；2nd, ribs adds the connection of slurry outlet passage and flap active tunnel
Intensity, strengthen the abrasion resistance of valve body, extend the valve life-span；3rd, increase the ratio of area of passage and access port sectional area, mitigate section
The influence to valve seat is flowed, extends its life-span.
The further preferred scheme of the utility model is：The valve seat heap is welded in valve body.
It is more firm by valve seat built-up welding with more preferable compared to intensity is detachably connected in valve body using above-mentioned technical proposal.
The further preferred scheme of the utility model is：The ribs one side relative with valve seat is arc surface and the circle
Radian corresponding to cambered surface is obtuse angle.
Using above-mentioned technical proposal, the radian corresponding to arc surface is obtuse angle, when by slurry impact, by it along circular arc
Face is distributed to surrounding, avoids directly impacting.
The further preferred scheme of the utility model is：Radius on the ribs corresponding to arc surface is more than the slurry
The 1/7 of access road port diameter.
Using above-mentioned technical proposal, under the operating mode that flow velocity is accelerated, slurry inlet access port diameter is bigger, arc surface institute
It is hit bigger, when the radius of arc surface is more than the 1/7 of slurry inlet access port diameter, the abrasion resistant effect of arc surface is bright
It is aobvious, it substantially prolongs the service life of valve body
The utility model is more preferably：Radius on the ribs corresponding to arc surface leads to for the slurry inlet
The 1/6 of road port diameter.
By using above-mentioned technical proposal, when the radius corresponding to arc surface is the 1/6 of slurry inlet access port diameter,
Extend the service life of valve body while avoiding reinforcement excessive and slurry is hindered.
The utility model is more preferably：The face of minimum overflowing end face between the slurry inlet passage and slurry outlet
Product is the 16/25 of the slurry inlet access port sectional area.
The utility model is more preferably：The slurry inlet passage, slurry outlet passage and flap active tunnel phase
Connection and be in Y-shaped；The flap active tunnel and the slurry outlet passage are in 45 degree of angles.
In summary, the utility model has the advantages that：First, valve body shaping is avoided between lower valve body
Easily there is the problem of leakage point under the fast operating mode of slurry flow rate in sealing surface；2nd, ribs add slurry outlet passage and
The bonding strength of flap active tunnel, strengthen the abrasion resistance of valve body, extend the valve life-span；3rd, area of passage and access port are increased
The ratio of sectional area, mitigate influence of the throttling to valve seat, extend its life-span.
