Start and stop carry out by rule of operation.Owing to the valve rod of standard valve is easily damaged by electrolytic corrosion, electrolyte crystalline particle damages
Non-return valve sealing surface or stuck rotating mechanism, valve is easy to lose efficacy, and unrepairable.
Utility model content
In order to solve above-mentioned deficiency of the prior art, a kind of split type non-return valve is proposed.
The technical solution of the utility model: a kind of split type non-return valve, including spool, valve rod, valve body be divided into upper valve body, under
Valve body, upper valve body, lower valve body be the flange of band boss, connected relative flange connecting hole by bolt, and two boss are relative up and down,
Under the endoporus aperture ratio of upper valve body, the endoporus aperture of valve body is big, and lower valve body opens a pair square groove near endoporus side, and square groove is with always
On line, axisymmetricly, valve rod two ends embed square groove, and limited location plate on valve rod, spool is that diameter is less than the endoporus aperture of upper valve body
Non-full circle plectane bigger than the endoporus aperture of lower valve body again, its area, less than the area of equivalent diameter semicircle, spool is fixed with
The spool ears or side handles of a utensil, the spool ears or side handles of a utensil are in spool straight flange side, and the spool ears or side handles of a utensil are hinged with limiting plate, limiting plate have gear convex, keep off convex restriction
The spool ears or side handles of a utensil rotate less than 90 degree, spool bottom surface lining acid-resisting rubber, are provided with sealing ring, a sealing ring part and valve between two boss
Contact at the bottom of core.
Described spool ears or side handles of a utensil angle of rotation is 30-87 degree.
The described spool ears or side handles of a utensil are connected by bolt, nut with limiting plate.
Described sealing ring is politef pad or acid-resisting rubber pad.
Technique effect of the present utility model: this non-return valve efficiently solves standard non-return valve in copper wet method electrolysis production system
In following point: electrolyte crystalline particle damages the sealing surface of non-return valve or stuck rotating mechanism, and valve rod is easily rotten by electrolyte
Deteriorating bad, valve is easy to lose efficacy, and unrepairable.This utility model has that simple in construction, corrosion resistance be strong, detachable, dimension
Repair the features such as convenience and length in service life.

Detailed description of the invention
As shown in Figure 1, 2, a kind of split type non-return valve, including spool, valve rod, valve body is divided into upper valve body 1, lower valve body 2, on
Valve body 1, lower valve body 2 are the flanges of band boss, are connected relative flange connecting hole by bolt, and two boss are relative up and down, upper valve
Under the endoporus aperture ratio of body 1, the endoporus aperture of valve body 2 is big, and lower valve body 2 opens a pair square groove near endoporus side, and square groove is at same straight line
Above, axisymmetricly, valve rod 6 two ends embed square groove, and limited location plate 5 on valve rod 6, spool 4 is the diameter endoporus aperture than upper valve body 1
Little non-full circle plectane bigger than the endoporus aperture of lower valve body 2 again, its area is less than the area of equivalent diameter semicircle, solid on spool 4
Surely having the spool ears or side handles of a utensil 9, the spool ears or side handles of a utensil 9 are in spool 2 straight flange side, and the spool ears or side handles of a utensil 9 and limiting plate 5 are hinged by bolt 8, nut 7, limit
Having gear convex 10 on the plate 5 of position, keep off the convex restriction spool ears or side handles of a utensil 9 and rotate less than 90 degree, spool 2 bottom surface lining acid-resisting rubber, between two boss
Being provided with sealing ring 3, sealing ring 3 part contacted with spool 2 end.Sealing ring 3 is politef pad or acid-resisting rubber pad.According to
Being actually needed design, change the angle of the trapezoidal hypotenuse having gear convex on limiting plate, the spool ears or side handles of a utensil 9 maximum rotation angle can be greatly to 87
Degree, little to 30 degree, prioritizing selection 60 degree.The processing of spool 4: with the diameter plectane more slightly smaller than the internal diameter of valve upper body 1, along centrage
One fixed width cuts in half.Along a point tangential direction, the spool ears or side handles of a utensil 9 that simultaneously welded bands is porose, another side lining acid-resisting rubber.
Requirement
1, this non-return valve is vertically-mounted, and spool upwardly opens；
2, assembling sequence: be first arranged on by valve rod 6 in the square groove of lower valve body 2, three contacted with lower valve body 2 are with argon arc welding
Welding；With bolt, the spool ears or side handles of a utensil 9 and limiting plate 5 are connected, and by spool fix in position；Install between valve body 1 and lower valve body 2
Sealing ring 3, and upper valve body 1 and lower valve body 2 are aligned；Sealing gasket between valve and pipe flange is installed and puts in place, then
Connect this non-return valve and pipe flange with the bolt that length is enough, and tighten.
3, tighten No leakage seepage, make regular check on the fastening situation of bolt, it is ensured that No leakage seepage at adpting flange.
Fluid upwards pressure, and when flowing up, spool 4 is rushed to open, fluid without upwarding pressure, tube fluid
Relying on deadweight to fall, spool 4 can not be flow backwards by fluid pressing, fluid.Limiting plate 5 determines the size of spool 4 open degree.
