The mounting groove 5 of axis installation, the valve outer wall are equipped with the drainage channel 6 that is connected to the mounting groove, on the drainage channel
Equipped with the switching device 7 for opening and closing the drainage channel.The waterproof water erosion end mechanism can be arranged on various valves, than
Such as butterfly valve, fixing ball valve can be drained needing the when of draining to turn on the switch device.
In the present invention, described as shown, the switching device includes the capping 71 being detachably connected with the valve body
Capping coordinates with the sealing of the drainage channel 6.In this embodiment, capping can directly be connect with valve body, be used in combination sealing ring real
It now seals, which can be that screw connects.
In the present invention, described as shown, it includes the drainage tube 72 being connect with the valve body also to wrap the switching device
The drainage channel 721 being connected to the drainage channel is equipped in drainage tube, the drainage tube outer end is equipped with the envelope being detachably connected
Lid 71, the capping coordinate with the sealing of drainage channel 721.When power plant steam pipeline deactivates, as pipeline cools down, interior steam is situated between
Matter gradually discharges, decrease temperature and pressure, and the steam medium in the non-protruding end of residual valve will be condensed into water, enter drainage by valve body
In pipe, capping（Reservoir 715 is equipped in capping）Storage；Also capping discharge ponding can be removed after valve deactivates cooling, to
Water erosion is eliminated to parts in valve（Such as divided ring 23, thrust pad 21）Influence.
In the present invention, as shown, the capping is connected by screw with the drainage tube.
In the present invention, as shown, the drainage tube is welded with the valve body.Leak point is reduced, sealing performance is more preferable.
