[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a steam trap water vaporizer that extinguishes steam that has become dull due to re-evaporation of condensate discharged from a steam trap.

[Prior art]
[Patent Literature]
JP, 2002-5394, A In this, a loop type thin pipe heat pipe is attached to the outlet side of a steam trap, and the re-evaporation of the condensate is suppressed by efficiently absorbing and dissipating the heat held by the condensate. There is a description of a water heater that can prevent the generation of steaming.
[0003]
[Problems to be solved by the invention]
Although the conventional steam heater can erase the moisture from the steam traps one by one, it ensures that the steam from the re-evaporation of the condensate discharged simultaneously from multiple steam traps. There was a problem that could not be erased.
[0004]
Accordingly, an object of the present invention is to provide a steam trap water heater capable of surely extinguishing the steam that has become dull due to re-evaporation of condensed water discharged from a plurality of steam traps.
[0005]
[Means for Solving the Problems]
The means for solving the above-mentioned problems is a condensate tank for storing condensate discharged from a plurality of steam traps, in which the condensate discharged from the outlet of the steam trap is used as a degassed steam that has evaporated again. A cooling fluid supply valve provided in the upper part of the condensate tank, a condensate discharge valve provided in the lower part, and the cooling fluid supply valve formed of a cooling fluid supply valve body made of steel balls, and the condensate A discharge valve is formed of a flat condensate discharge valve body, a water level detection means for detecting the water level of the condensate tank is attached, and the water level detection means is a hollow spherical float disposed inside the condensate tank. The connecting shaft is used to open and close the cooling fluid supply valve and the condensate discharge valve provided in the condensate tank according to the detection operation of the water level detecting means.

DETAILED DESCRIPTION OF THE INVENTION
A condensate tank provided with a cooling fluid supply valve and a condensate discharge valve, and a water level detecting means for detecting the water level of the condensate tank are attached, and the cooling fluid supply valve and the condensate are adjusted according to the detection operation of the water level detecting means. By opening and closing the discharge valve, when a predetermined amount of condensate has accumulated in the condensate tank, the cooling fluid supply valve is opened and cooling fluid is supplied into the condensate tank to cool the condensate. When the water level reaches a predetermined level, the condensate discharge valve opens and the condensed condensate in the condensate tank is discharged to the outside. Can do.

【Example】
As shown in FIG. 1, a condensate tank 2 connected to the outlet sides of a plurality of steam traps 1, a cooling fluid supply valve 3 provided at the top of the condensate tank 2, a condensate discharge valve 4 provided at the bottom, The steam trap water heater is composed of the water level detecting means 5 for detecting the water level in the condensate tank 2.
[0008]
The condensate tank 2 has a vertically long cylindrical shape, and a water level detecting means 4 comprising a hollow spherical float 6 and connecting shafts 7 and 8 is attached to the condensate tank 2 so as to be movable up and down. The spherical float 6 and the connecting shafts 7 and 8 are integrally attached by welding, and a holding member 11 that holds the vertical movement of the connecting shaft 7 and restricts the lateral displacement is attached to the upper portion of the connecting shaft 7.
[0009]
A cooling fluid supply valve body 9 made of a steel ball is disposed on the supply valve seat 10 in a free state at a predetermined distance above the connecting shaft 7. A lid 12 for sealing the periphery of the cooling fluid supply valve body 9 and the supply valve seat 10 is attached, and a cooling fluid supply pipe 13 is connected to the lid 12. Therefore, the high pressure cooling fluid from the cooling fluid supply pipe 13 stays in the lid inner chamber 14.
[0010]
A flat condensate discharge valve body 15 is integrally attached to the lower part of the connecting shaft 8. Discharge valve seats 17 having through holes 16 are disposed on the left and right sides of the condensate discharge valve body 15. A condensate discharge pipe 19 is connected to the discharge valve seat 17 through an outlet hole 18. The condensate discharge valve body 15 is disposed in the discharge valve seat 17 so as to be movable up and down.
[0011]
Condensate discharged from the plurality of steam traps 1 flows into the condensate tank 2 and stays there. The state shown in FIG. 1 is a state where the condensate water level in the condensate tank 2 has reached a little over half, and both the cooling fluid supply valve body 9 and the condensate discharge valve body 15 are closed. When condensate further flows into the condensate tank 2 from this state and the water level rises, the spherical float 6 also rises, and the connecting shaft 7 pushes the cooling fluid supply valve body 9 from the supply valve seat 10, thereby The high-pressure cooling fluid in the chamber 14 is injected into the condensate tank 2, and the condensate in the condensate tank 2 is cooled. In this case, the lower condensate discharge valve body 15 is still closed.
[0012]
When the water level in the condensate tank 2 further rises due to the condensate from the plurality of steam traps 1 and the inflow of cooling fluid, the amount of cooling fluid supplied from the cooling fluid supply valve body 9 increases and the condensate discharge valve body 15 Is opened, and the cooled condensate in the condensate tank 2 is discharged to the outside through the outlet hole 18 and the condensate discharge pipe 19. In this case, since the condensate in the condensate tank 2 is sufficiently cooled by the cooling fluid, it does not re-evaporate, and therefore, mist and steam do not rise.
[0013]
As condensate is discharged from the condensate discharge valve body 15, the spherical float 6 is lowered together with the water level in the condensate tank 2. When the condensate discharge valve body 15 is lowered to a predetermined water level, the condensate discharge valve body 15 is closed and condensate. Stop discharging.
[0014]
【The invention's effect】
As described above, according to the present invention, it is possible to reliably extinguish the steam that has been caused by re-evaporation of condensed water discharged from a plurality of steam traps.
