Abstract

The utility model relates to a fully lined fluoroplastic pneumatic stop valve for chlor-alkali, in particular to a fluoroplastic pneumatic stop valve for chlor-alkali for controlling and regulating the flow of medium on a pipeline in the chemical industry. The stop valve comprises a valve body, a valve flap, a valve cap, a gland, a driving rod and an executing mechanism, wherein an annular seal ring is positioned between the valve cap and the valve rod, grooves are respectively formed on the inner surface of the valve body, the inner surface of the valve cap and the outer surface of the valve flap, anticorrosive coatings are respectively arranged on the inner surface of the valve body, the inner surface of the valve cap and the outer surface of the valve flap, the anticorrosive coatings infiltrate into the grooves, and respectively form a whole on the same surface. The stop valve has the advantages of good wear resistance and sealing property, uneasy falling and damage, uneasy leakage and long service life.

Description

The alkali-chloride special-purpose fluoroplastic all-liner pneumatic stopping valve
Technical field
The utility model relates to a kind of valve, relates to the alkali-chloride special-purpose fluoroplastic pneumatic stopping valve of controlling and regulate media flow on a kind of chemical industry pipeline specifically.
Background technique
At present, the valve that China's chemical industry is used for the control of deep-etching flowing medium such as chlorine mostly is the plain cast iron hand stop valve of no liner or part liner greatly, form and structure are unreasonable owing to be tightly connected, Sealing easily come off damages, easily leakage, even generation security incident, can't realize telecontrol, valve is short working life, changes frequent, influence is produced, and causes economic loss.
The model utility content
The purpose of this utility model is to provide a kind of sealing configuration novelty, and good seal performance is safe and reliable, and long service life can realize the alkali-chloride special-purpose fluoroplastic all-liner pneumatic stopping valve of telecontrol.
The utility model comprises valve body, flap, valve gap, gland, drive link, actuator, be equipped with O-ring seal between described valve gap and the valve rod, the outer surface of described valve interior surface, above-mentioned valve gap internal surface, above-mentioned flap is provided with groove respectively, the outer surface of described valve interior surface, valve gap internal surface, flap is provided with anticorrosive coat respectively, described anticorrosive coat infiltrates in each groove, and forms whole on same surface respectively.
The utility model wear resistance, good airproof performance, difficult drop-off damages, the difficult leakage, long service life.
The width of rebate of described groove is not more than the bottom land width.More stable after making the anticorrosive coat infiltration fixed, difficult drop-off.
On the described flap through hole is set, corresponding anticorrosive coat infiltrates in the through hole.The anticorrosive coat of flap upper and lower surface is connected as a single entity, and anti-corrosion layer structure is firm, is difficult for dislocation, good seal performance.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
As shown in Figure 1, 2, the utility model comprises valve body 1, flap 2, valve gap 3, gland 4, drive link 5, actuator 6, between valve gap 3 and the flap 2 O-ring seal 31 is set.。
The outer surface of valve body 1 internal surface, valve gap 3 internal surfaces, flap 2 is uniform groove 7 respectively, the outer surface of valve body 1 internal surface, valve gap 3 internal surfaces, flap 2 is provided with anticorrosive coat 8 respectively, each anticorrosive coat 8 infiltrates respectively in the corresponding grooves 7, forms whole on same surface respectively.
Because there be two kinds on air to open type and air to close type in such actuator 6, now the valve event principle is described with air to open type actuator.Be input to actuator 6 through the source of the gas that configures, actuator 6 drives flap 2 by connecting rod 5 and moves upward valve opening.
