Abstract
A combined shunt valve relates to a shunt valve of a bag filter. The prior valve has the problem of air leakage. The shunt valve always adopted for the time being essentially has a multi tablet butterfly-shaped valve plate composite structure, which is deformed when being heated, forming a large gap between each valve plate, resulting in loosely close of the valve. The production comprises: a group of valve bodies (15) equipped with a valve base (3), a guide rod (1) arranged at the lower end of the valve body, a sealing gasket (2) embedded on the upper part of the valve bodies (15), and a valve plate (5) forming a rigid-lined sealing structure with the valve base (3), an electric handspike (6) arranged above the valve plate (5), a separator and a guide groove arranged between the valve bodies (15), and a sealing rubber ring (4) arranged between the valve plate (5) and the valve base (3). The product is used as the shunt valve of the bag filter.
Description
Technical field:
The utility model relates to the by-pass valve on a kind of sack cleaner.
Background technique:
Can work normally in order to guarantee the filter bag in the sack cleaner, avoid improper boiler smoke that filter bag is caused damage, guarantee not influence the steam generator system proper functioning, need to be provided with bypath system between the import of sack cleaner and outlet, the parts that wherein need to be provided with most critical are combination bypass valve.When the sack cleaner proper functioning, meet NBS for making smoke emissioning concentration, must guarantee that the leak-down rate of combination bypass valve is 0.Simultaneously, when improper flue gas appears in boiler, combination bypass valve want can be fast and safely unlatching.The general at present by-pass valve that adopts is essentially multi-disc fly valve board combining structure or traditional lifting type structure, and multi-disc fly valve board combining structure can produce distortion when being heated, make the very big gap of generation between each sheet valve plate, causes valve closing not tight.Traditional lifting type structure though can guarantee the influence of not temperature distortion of valve, is that face contacts at valve plate and valve seat, causes certain dust stratification easily, causes valve closing not tight.More than two kinds of by-pass valves all can not effectively protect the filter bag of sack cleaner, in case filter bag is compromised, will cause great loss.
Summary of the invention:
The purpose of this utility model provides a kind of Security that improves the sack cleaner operation, can effectively protect filter bag, thereby guarantees the sack cleaner combination bypass valve of the proper functioning of steam generator system.
The purpose of this utility model is achieved in that
Combination bypass valve, its composition comprises: one is assembled with the valve body of valve seat, described valve body lower end is equipped with guide rod, be embedded in valve body top seal pad, valve plate and described valve seat are the nonflexible line sealing configuration, electric pushrod is equipped with in described valve plate top, and dividing plate and guiding groove are housed between the described valve body, between described valve plate and the described valve seat O-ring seal is housed.
Above-mentioned combination bypass valve, described nonflexible line sealing configuration are that described valve plate concave form spring steel steel plate contacts with the valve seat middle part in the middle part of it, edge and the sealing of valve seat limit wing nonflexible line.
Above-mentioned combination bypass valve, upper sealing panel and corresponding last plate and access door are equipped with in the described valve body outside, and drive motor and rain cover thereof are housed on the described valve body, and the electric pushrod bearing.
Above-mentioned combination bypass valve, lower seal plate, lower plugboard and following guiding groove are equipped with in described valve body below.
This technological scheme has following beneficial effect:
1. improve the Security of sack cleaner operation, can effectively protect filter bag, thereby guaranteed the proper functioning of steam generator system.
2. valve plate 5 is the spring steel steel plate, it during work the concave form, the middle part contacts with valve seat 3 middle parts, play positioning action, edge and valve seat 3 limit wing nonflexible line sealings, thus eliminate the influence of thermal denaturation to sealing configuration, valve port is through machining simultaneously, smooth surface contacts with the valve plate bit line, so there is not fouling phenomenon.So behind the assurance valve closing, leak-down rate is 0.
3. with crossing dividing plate 16 valve body 14 is divided into 3 parts, thereby realize that 3 groups of unit form the cordwood composite structure, plate 8, lower plugboard 13 and access door 11 in the cooperation can be realized online switching maintenance, unit combination quantity is 1～12, and the open and close of valve plate all can independently be controlled in each unit.
4. guide rod 1 is 0.5mm with the interior interporal lacuna of valve seat, plays accurate leading role, has guaranteed that valve plate and valve seat contraposition are accurate, helps improving the sealing of valve.
5. valve plate drives by electric pushrod, can open and close fast, thereby satisfy the application requirements of combination bypass valve, and the valve plate diameter range can be reached for φ 300mm～φ 2000mm.
6. valve seat 3 and valve body 14 are connected by bolt, its Sealing is an exotic material, and the bottom of valve body 14 is a flue gas inlet, and the side is a smoke outlet, be equipped with guiding groove in import and outlet port, when one of them unit of combination bypass valve need overhaul, plate can be inserted along guiding groove, until a unit is all switched, other two unit can work on, after maintenance finishes, plate is taken out, simultaneously socket is sealed with sealing plate.
