Trip uses single-piston valve seat, and downstream uses double piston valve holder structure, when valve body middle chamber superpressure is (more than or equal to the 1.33 of nominal pressure
Times) when, medium will push upstream valve seat, is detached from valve seat and sphere, reaches self-relieving function.To guarantee valve, pipe
Road it is safer, more reliable.Due to its performance requirement, technical characteristic, the particularity of operating condition, the product is made to also form other productions
Not the characteristics of product do not substitute.It is the natural gas of H2S containing high concentration, SO2 that ESDV Pneumatic single-action upper-mounting type ball valve, which uses medium,
Pressure rating is CL1500, inside nominal diameter 100mm, material: INCONEL 825, INCONEL 625.It is widely used in petroleum, stone
The facilities such as change and chemical industry, have far-reaching social benefit.
Import is had relied on before ESDV Pneumatic single-action upper-mounting type ball valve, the valve production cycle is long, expensive.And
Used in H2S containing high concentration, the natural gas of SO2, petrochemical industry and chemical industry this link, especially core product ESDV Pneumatic single-action
Upper-mounting type ball valve needs to make the expenditure of country relatively large from developed country's import completely.The ESDV nickel of Development of Domestic
Based alloy upper-mounting type ball valve, captures domestic market, will make biggish contribution for the economic construction of country.
Utility model content
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide fill formula on a kind of ESDV Pneumatic single-action
Nickel-base alloy ball valve, simple and compact for structure, valve body reduce leakage point using meter is installed in integral type, guarantee that sealing more may be used
It leans on.
Formula nickel-base alloy ball valve is filled on a kind of ESDV Pneumatic single-action of the utility model, mainly by valve body, downstream valve
The unidirectional lip-shaped ring of seat, sphere, valve deck, valve rod, bracket, pneumatic actuator, preloading spring, upstream valve seat, internal pressure, internal pressure external pressure are double
It is formed to lip-shaped ring, for the sphere installation in valve body, upstream valve seat is mounted on the left side between sphere and valve body, downstream valve
Seat is mounted on the right side between sphere and valve body, and the valve rod is mounted on the top of sphere, and bracket is mounted on the top of valve rod,
The pneumatic actuator is rack-mount, and the unidirectional lip-shaped ring of the internal pressure is mounted in downstream valve seat, and internal pressure external pressure is double
It is mounted in upstream valve seat to lip-shaped ring.
Further, the upstream valve seat uses single-piston structure, and downstream valve seat uses dual-piston structure.Work as valve body middle chamber
When pressure is more than 1.33 times of rated pressure under valve design temperature, medium power can be such that the unidirectional lip-shaped ring of internal pressure in upstream valve seat pushes away
It opens and realizes automatic drainage function, will not cause damages because of superpressure in valve body middle chamber to other component.
Further, the upstream valve seat uses unidirectional lip seal, and downstream valve seat uses two-way lip seal.
The utility model has the following beneficial effects: there is small in size, light-weight, sealed reliable, without maintaining, using the longevity
The advantages that life is long, easy to operate.
