Description
Technical field
This utility model relates to valve field, is specifically related to a kind of supercritical High Temperature High Pressure bivalve butterfly sealing ring type to folder check-valves.
Background technology
Traditional check-valves is to control medium to flow backwards.It is very big that flange form valve size is opened in single-lobe rotation, and structure length is long, and when flap is opened, stroke is long, needs the longer shut-in time, and fluid resistance is big, can only use on the common unit of power plant.
Bivalve butterfly sealing ring type is to folder check-valves, and structure length is short, volume is little, lightweight, drops this net income increase.During installation, pipeline can be horizontally mounted or right angle setting.Valve flowing channel is unobstructed, and fluid resistance is little, is active in one's movements, good seal performance.
Flap stroke is short, and closing velocity is fast, and water bell pressure is little.In a word, overall structure is simple, compact, handsome in appearance, and service life is long, and security reliability is high, uses on power plant's supercritical unit.
Former valve uses temperature at 425 degree, and pressure is at below 900LB, it is impossible to meet the applying working condition of current high pressure, high-temperature.
Summary of the invention
In order to solve the problems referred to above, the utility model proposes a kind of supercritical High Temperature High Pressure bivalve butterfly sealing ring type to folder check-valves, design ingenious; easy to use; pressure increases, and solves valve and can bear the applying working condition of high pressure, high-temperature, the problem that protection valve uses safety.
In order to reach foregoing invention purpose, the utility model proposes techniques below scheme:
Supercritical with High Temperature High Pressure bivalve butterfly sealing ring type to folder check-valves, it includes valve body, flap, spring, alignment pin, bearing pin, fixing seat, fixed block, limited block, bolt, equipped with flap in the middle of valve body, valve seat it is designed with between flap and valve body, flap is formed by flap by two and half, flap is rotated in installation valve body by bearing pin by two and half, alignment pin is passed through equipped with limited block in centre position, valve outlet side, equipped with spring in the middle of bearing pin, bearing pin two ends are contained in fixing seat and are bolted, two and half to being respectively designed with block on rear side of flap, spring one end is supported on the right side of top block, spring opposite side is supported on the left side of lower section block, it is designed with closure gasket groove on the sealing surface of valve body rear and front end, surrounding valve body is designed with several bolts hole；Half on rear side of flap equipped with fixed block, flap is arranged on bearing pin by half by fixed block.Fixed block is installed by bearing pin, plays fixing flap effect, and such flap will not left and right play.
Being designed with a projection on described block, described upper and lower both sides, limited block front end are respectively designed with fixture block, and during valve opening, projection is stuck in fixture block side.
Sealing surface between described flap and valve seat is hard alloy sealing surface.
Design F316 sealing ring in described closure gasket groove.
Described supercritical High Temperature High Pressure bivalve butterfly sealing ring type is less than 600 degrees Celsius to the use temperature of folder check-valves.
Described supercritical High Temperature High Pressure bivalve butterfly sealing ring type is Supercritical materials C12A to the valve body material of folder check-valves.
Described supercritical High Temperature High Pressure bivalve butterfly sealing ring type is below 2500Lb to the pressure of folder check-valves.
The utility model has the advantages that structure is different: flange form is opened in the rotation of former single-lobe, existing bivalve butterfly sealing ring wafer type.Material is different: former common material WCB, existing Supercritical materials C12A.Use temperature increases: former less than 425 degree, existing 600 degree.Pressure increases: former below 900Lb, existing 2500Lb.Valve seat uses fixed structure, sealing surface weld deposit hard alloy, improves corrosion resistance and the wearability of valve, extends the service life of valve.
