Description
Technical field
The present invention relates to the design fields of corrugated tube valve special for chlorine door.
Background technology
Currently, China's chemical industry is general common chlorine for the valve of chlorine, liquid chlorine pipeline medium control media flow
Air valve, due to not having special feature in selection or on valve mechanism, on the one hand the performance of this valve is unstable,
Sealing effect is bad；On the other hand under the poisonous and hazardous process conditions of burn into, poor corrosion resistance easily leaks, and shell is easily worn
Hole, bellows is easy to wear short so as to cause valve whole service life, cannot meet the particular/special requirement of permanently effective pumped (conveying) medium,
And poisonous medium is once a leak occurs, prodigious harm can be brought to surrounding enviroment and personal safety.
Invention content
Present invention aims in view of the above problems, providing that a kind of sealing effect is good, is not easy to leak, height with long service life
Performance nano coating corrugated tube valve special for chlorine.
The present invention include valve body, valve seat, flap, bellows component, valve deck, valve rod, gland, drive link, guide pad,
Transmission nut, handwheel；The valve seat, flap, valve rod are respectively arranged in valve body, and the flap is set to the end of valve rod；Institute
Valve deck is stated to be set to above valve body；The valve rod upper end passes through biography by guide pad and drive link floating connection, the drive link
Dynamic nut is connect with handwheel；The bellows component is set between valve deck and valve rod；The bellows component includes bellows,
Stuffing-box is set above the bellows, and the stuffing-box upper end is welded with valve deck；Positioning is set below the bellows
Axle sleeve, the positioning shaft sleeve are welded with valve rod；Airtight and watertight padding is set in the stuffing-box；The gland is set to sealing
It is bolted above filler and between valve deck.
Airtight and watertight padding of the present invention uses polytetrafluoroethylene packing, and the insurance as valve rod seals, and bellows is effectively prevent to damage
It is bad, medium is controlled in valve body intracavitary, prevents from leaking outside；Bellows component stuffing-box of the present invention upper end is welded with valve deck, lower end
Axle sleeve is welded with valve rod, and effectively fluid is controlled in valve body intracavitary, and multi-stage sealed, raising sealing effect is formed with this.This
Invention valve body uses LCB low temperature carbon steel solid investment castings, and operating mode cannot be met by solving previous normal steel casting cryogenic property
Requirement, individual producers do not meet the prescribed requirement of relevant national standard more using spheroidal graphite cast-iron, perishable, perforation,
Security risk is big；Guide pad is formed using CF8 stainless steel material essence castings, solves to use ductile cast iron material easy-to-rust in the past, hair
The generation of raw card resistance or even phenomenon of rupture, securely and reliably.
Anti-corrosion protection coating is respectively set on the surface of the valve body, flap, valve deck, valve rod and media contact in the present invention.
Anti-corrosion protection coating used is Cr/Cr (X) N nano composite ceramic coatings, after coating, not only ensure that the interior anti-of flow medium
Corruption, and ensure that the outer anti-corrosion of valve, it solves the outdoor installation of valve or chemical industry operating mode atmospheric corrosion, reaches safety, ring
It protects, energy-efficient effect.
Airtight and watertight padding of the present invention is multistage " V " shape airtight and watertight padding, enhances sealing effect, can be in bellows because long-term
After fatigue damage, effectively fluid media (medium) is controlled in valve body intracavitary, the leakage of medium is effectively controlled, is fully achieved zero
Leakage.
Valve seat upper surface of the present invention is equipped with annular groove, is arranged in the annular groove and matches with annular groove shaped
The sealing element of conjunction；The sealing element is integrated with valve seat sintering, improves sealing performance.
The present invention is wholely set frustum in the lower face of the flap, and the frustum and the sealing element cooperation on valve seat are close
Envelope, is equipped with hard alloy layer on the contact surface of the frustum and sealing element, and the sealing element of hard alloy layer and valve base surface is matched
It closes, forms cone, plane dual-seal, fully meet the design effect of valve interior sealing zero leakage；Valve clack sealing surface hard closes
Gold forms hard soft seal with sealing surface of seat polytetrafluoroethylene (PTFE) and matches, and valve seat has the effect of that sealing compensates automatically, to reach
It is gap-free sealed, leakage in zero is fully achieved.
