Abstract
The utility model provides a diaphragm valve with a ceramic lining to overcome the disadvantages of easy aging, poor wear resistance, easy medium pollution, short long lifetime, poor high-temperature resistance, etc. of the diaphragm valves with rubber or plastic linings. The utility model is realized by that the burned ceramic material lining is organically combined with a casing manufactured by metallic materials and a diaphragm, a valve rod, a copper nut, a hand wheel, etc. are jointly combined. The utility model can be widely used for the petroleum industry, the chemical engineering industry, the metallurgy industry, the pharmacy industry, the light industry, etc.
Description
The utility model relates to membrane valve, is lined with the membrane valve of anti-corrosion material in particularly a kind of.
In the industrial production of reality, main etch-proof membrane valve has two classes.A kind of is lining diaphragm of rubber valve, and a kind of is lined with fluoroplastic material membrane valve.They have certain shortcoming: lining diaphragm of rubber valve is not corrosion-resistant in strong acid and strong base; Though the membrane valve of lined with fluoroplastic material is corrosion-resistant, the easy delamination of fluoroplastics lining is dropped.In addition, adopt the membrane valve of organic material lining that the shortcoming of lacking in non-refractory and working life is all arranged.
The purpose of this utility model promptly is to provide a kind of corrosion resistance stronger, lining long service life, the membrane valve of not delamination of lining.
The utility model has adopted stupalith to make lining, and ceramic lined has incorrosive substantially characteristic under strong acid and strong base, and high temperature resistant and anti-washing away.In addition, ceramic lined can not pollute pipeline medium, so this lining ceramic diaphragm valve is applicable to all gases, liquid environment, and alternative existing General Purpose Rubber membrane valve or lining fluorine membrane valve.
" Fig. 1 " is the present invention's " lining ceramic diaphragm valve " structural representation.
1, ceramic-lined 2, the adhesive layer 3 of whole valve body, valve body metal shell 4, barrier film 5, concave-convex shape rubber plate 6, sphere shape flap 7, valve upper cover 8, screw rod 9, nut 10, handwheel
Be described below in conjunction with " Fig. 1 ":
With whole the ceramic body liner (1) of the setting of sintering therein with left and right two involutory metal shells (3) inclusion, leave certain clearance between ceramic-lined (1) and the metal shell (3), with perfusion or gluing method binding material is filled in the gap, binding material is decided on operating temperature, and hot environment adopts inorganic glue.Technique for sticking is looked selected adhesive material and is different.
Barrier film (4) adopts fluoroplastic or fluorine rubber, and barrier film (4), concave-convex shape rubber plate (5) connect together with sphere shape flap (6), and screw rod (8) and sphere shape flap (6) also are interconnected.Rotate handwheel (10), can drive barrier film (4) and close operation with Open valve, barrier film (4) can be changed easily.
Thick mouthful of design of flange adopted at valve body ceramic-lined (1) flange two ends, and its effect is equal to flange facing, so medium can not leak because of the flange facing corrosion.
So, the utility model adopts ceramic lined and by above-mentioned specific design, has not only overcome many disadvantages of existing corrosion protection membrane valve, and also has high temperature resistant anti-washing away and the advantage of pollution medium not.
Claims (3)
1, lining ceramic diaphragm valve, form by ceramic-lined (1), valve body metal shell (3), barrier film (4), concave-convex shape rubber plate (5), sphere shape flap (6), valve upper cover (7), screw rod (8), nut (9), handwheel (10), it is characterized in that ceramic-lined (1) is the integral single piece structure, valve body metal shell (3) is coated on outside ceramic-lined (1).
2, lining ceramic diaphragm valve according to claim 1, it is characterized in that ceramic-lined (1) is primary has two ends flange facing and a lumen flange facing.
3, lining ceramic diaphragm valve according to claim 1 is characterized in that between valve body metal shell (3) and ceramic-lined (1), adopts the organic or inorganic binder to carry out adhering junction.
