Abstract
The utility model relates to an ultra supercritical takes spherical sealed check valve of bypass. It includes valve body, valve gap, ball sealer, slip through the net, pendant collet, apron, clamping ring, hard self sealss circle, governing valve, pipe, is equipped with the ball sealer in the valve body, and the design has sealed face between ball sealer and the valve body, is equipped with in the valve pocket of valve body and slips through the net, and the ball sealer is equipped with the governing valve in the well up -and -down motion of slipping through the net, the valve body outside, and the valve pocket that the ball sealer upper end is connected to the pipe is passed through to governing valve one end, and the governing valve other end passes through the pipe and connects valve body export runner. The advantage be in the bypass governing valve of installation, the speed of adjust replenishing the medium, the very fast valve of closing under the circumstances that does not take place the water hammer, the protection valve is safe in utilization, the ball sealer is the up -and -down motion in the cylinder is slipped through the net, and is arbitrary rotatory, does not have the driving medium, freely opens and close, does not have fixed wearing and tearing point, has improved the life of sealing member, the cylinder has been slipped through the net and has been led and the guard action.
Description
Technical field
This utility model relates to field of check valves, is specifically related to a kind of ultra supercritical band bypass spherical sealed check-valves.
Background technology
Traditional non-return flap is to control medium to flow backwards.In order to reduce energy consumption, improving generating efficiency, generating equipment is just towards maximization, high parameter, high-performance development.
Spherical sealed check-valves does not structurally have driving member, freely opens and closes, and ball sealer is slipped through the net inner up and down motion at cylinder, arbitrarily rotates, there is not fixing wear point.In work process, sphere abrasion is uniform, remains good form accuracy, and serviceability will not reduce in time, improves the service life of sealing member.
In pressure duct, when occurring that medium flows backwards, high-pressure medium return pressure can make ball sealer closedown extremely fast, and valve and pipeline will be caused powerful water attack by this, thus produce device and destroy, impact safety in production.
Summary of the invention
The utility model proposes a kind of ultra supercritical band bypass spherical sealed check-valves, valve mainly uses spherical sealed structure, and pressure increases, and solves valve and comparatively fast closes valve in the case of there is not water attack, and protection valve uses the problem of safety, meets applying working condition.
nullUltra supercritical band bypass spherical sealed check-valves，It includes valve body、Valve gap、Ball sealer、Slip through the net、Pendant collet、Cover plate、Pressure ring、Hard self sealss circle、Regulation valve、Pipe，Valve body is built with ball sealer，Sealing surface it is designed with between ball sealer and valve body，The valve pocket of valve body is built with slipping through the net，Ball sealer moves up and down in slipping through the net，Valve gap is contained in valve body upper end，Hard self sealss circle it is sequentially arranged with from the bottom up between valve gap and valve body、Pressure ring、Pendant collet，Hard self sealss circle lower end is pressed on valve gap，Hard self sealss circle upper end is pressed with pressure ring，Pendant collet it is pressed with above pressure ring，The edge of pendant collet embeds in valve body，Valve body upper end is fixedly connected on valve gap by stud and nut equipped with cover plate and cover plate，Equipped with suspension ring in the middle of cover plate upper end，Equipped with regulation valve outside valve body，Regulation valve one end connects the valve pocket of ball sealer upper end by pipe，The regulation valve other end connects valve outlet runner by pipe.
The pressure of described valve body is 270V.
Described valve body lower end has porus excretorius, and porus excretorius is built with plug.
The utility model has the advantages that and install a regulation valve in bypass, regulation supplements the speed of medium, closes valve in the case of there is not water attack faster, and protection valve uses safety.Ball sealer is slipped through the net inner up and down motion at cylinder, arbitrarily rotates, does not has driving member, freely open and close, there is not fixing wear point, improves the service life of sealing member.Cylinder has been slipped through the net and has been guided and protective effect.Pressure increases: former below 170V, is now 270V；Self sealss: former soft seal, existing for hard sealing.Increase mudhole, remove dirt.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
