Abstract
The utility model discloses a combined poppet valve, wherein most of the original products are in a multichip butterfly valve board composite structure or a traditional lifting type structure. The composite structure of the multichip butterfly valve board can be deformed during heating period, and a big gap can be generated among each valve board, which leads the valve not to be tightly closed. The combined poppet valve comprises a valve body (1), a valve seat (4) which is arranged in the valve body (1) and a valve board (5). A guide driving part which is connected on the valve body (1) is connected with a baffle plate (2) through the valve seat (4) which is connected with the valve board (5). The baffle plate (2) which is mounted on the valve seat (4) lineally contacts with the valve body (1). The combined poppet valve can be applied in high-temperature dust-removing valves.
Description
Technical field:
The utility model relates to a kind of valve that is used for dedusting.
Background technique:
Dust pelletizing system is the part of whole steam generator system as the boiler accessory machinery system, in order better to adapt to the needs of steam generator system proper functioning, bypath system must be set in dust pelletizing system, and wherein the parts of most critical are the combination poppet valve.It is 0 that dust pelletizing system requires valve leak-down rate when off working state, unlatching that can be fast and safely in the time of in working order.Valve in the bypath system is generally multi-disc fly valve board combining structure or traditional lifting type structure at present, 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.
Summary of the invention:
The purpose of this utility model provides a kind of high-temperature systems that is used for and closes the leak free dedusting valve in back.
Above-mentioned purpose realizes by following technological scheme:
The combination poppet valve, its composition comprises: valve body, be installed in valve seat and valve plate in the described valve body, the guiding drive part that is connected on the described valve body links to each other with dividing plate by the valve seat that is connected with valve plate, and the described dividing plate that is installed on the described valve seat contacts with described valve body line.
The combination poppet valve, described guiding drive part comprises guide rod, guide holder and gas actuating device, when the guide holder outside that is with guide rod in described is connected with work in the middle of the described valve plate of level and smooth depression, be equipped with described valve seat under the described valve plate.
The combination poppet valve, described valve plate is connected by abrasion-resistant metal seal ring rigid seal contact-type with described valve seat, and described valve plate lower end is equipped with barge board.
The beneficial effects of the utility model:
1. the utility model has been developed a kind of combination poppet valve, and it has improved the Security of dust pelletizing system, can effectively guarantee the proper functioning of steam generator system.
2. valve plate is the spring steel steel plate, is the concave form during inoperative, and the middle part contacts with the guide holder middle part, edge and abrasion-resistant metal seal ring point of contact form the nonflexible line sealing, thereby eliminate the influence of thermal denaturation to sealing configuration, also fouling phenomenon can not occur, so behind the assurance valve closing, leak-down rate is 0.
3. guide holder not only plays good guide but also play the effect of locating valve plate.
4. barge board can be valve opening effective barrier air of moment washing away valve seat and seal ring.
5. the utility model combination poppet valve is connected on the bypass airduct road by flange, and 1 dividing plate 2 is divided into 2 parts up and down with valve body 1,4 valve seats is set on dividing plate top, thereby realizes 4 modular constructions, and this structure is saved the space.
6. guide rod 6 is 0.5mm with guide holder 7 interior interporal lacunas, can play accurate leading role, has guaranteed that valve plate and valve seat contraposition are accurate, helps improving the sealing of valve.
7. valve plate drives by cylinder, can guarantee the quick open and close of valve plate, satisfies the application requirements of combination poppet valve
