Dish type, hydroecium are communicated with water inlet pipe and outlet pipe, and water inlet pipe connects the lower left side in room stack shell, and outlet pipe is connected in hydroecium
Hydroecium stack shell upper right；The inner coil pipe is installed in hydroecium, and water chamber head is used to close hydroecium, and the input of inner coil pipe
The straight length with water chamber head welding is equipped with output end, the input of inner coil pipe and the straight length of output end seal with hydroecium
Head outer surface uses argon arc welding, and sealing shroud is made up of sleeve pipe and seal closure, and sleeve pipe is respectively fitted over the straight of input and output end
On pipeline section, antihunting device is set, antihunting device is made up of lamellar, is clamped in the end of inner coil pipe on inner coil pipe.
Further, the inner coil pipe is square inner coil pipe.
Further, the sealing shroud is flared structure made of PVC material.
Further, the seal closure is close to water chamber head inner surface, covered with weld seam.
Further, the straight length is provided with multilayer scrobicular ring.
Further, the inwall of described sleeve pipe is provided with least two layers and scrobicular ring interference fit on the straight length of inner coil pipe
Bulge loop.
Compared with prior art, under use state of the present utility model, inner coil pipe long period of soaking is in water, due to sealing shroud
It is interference fitted with inner coil pipe, simultaneously because sealing shroud is flared structure made of PVC material, under hydraulic pressure effect, sealing shroud
Interior gas is extruded out, and sealing shroud adsorbed close has in the inner surface of water chamber head, intimate vacuum state in sealing shroud
Effect ground wraps up the welding position of inner coil pipe and its neighbouring straight length, is allowed to isolate with chlorion in water and water, so as to favourable
Welding position and chemical reaction is further produced with inner coil pipe in preventing that chlorion from entering, play sealing corrosion to a certain extent and make
With slow down the speed that inner coil pipe is corroded, extend the service life of inner coil pipe；Antihunting device is set on inner coil pipe, prevented
Vibrating device is made up of lamellar, is clamped in the end of inner coil pipe, avoids the excessive caused vibration of inner coil pipe no-support spaning distance.
