Checking the Piping

Use only under conditions in which no water hammer will occur. The

impact of water hammer may damage the product, leading to fluid

discharge, which may cause burns or other injury.

CAUTION

Check to make sure that the pipes to be connected to the product have been

installed properly.

1. Is the pipe diameter suitable?

2. Is the piping where the product is to be installed horizontal?

3. Has sufficient space been secured for maintenance?

4. Have maintenance valves been installed at the inlet and outlet? If the outlet is

subject to back pressure, has a check valve (TLV-CK) been installed?

5. Is the inlet pipe as short as possible, with as few bends as possible, and installed

so the liquid will flow naturally down into the product?

6. Has the piping work been done correctly, as shown in the figures below?

Requirement

Correct

Incorrect

Install catchpot with the

proper diameter.

Diameter is too small.

Make sure the flow of

condensate is not

obstructed.

Diameter is too small and inlet

protrudes into pipe interior.

To prevent rust and

scale from flowing into

the trap, the inlet pipe

should be connected

25 to 50 mm (1 to 2 in)

above the base of the

T-pipe.

Rust and scale flow into the

trap with the condensate.

When installing on the

blind end, make sure the

flow of condensate is not

obstructed.

Condensate collects in the

pipe.

Operation

Principles of air and condensate discharge:

1. Start-up Air and Cold Condensate Discharge

At start-up, before steam is supplied the system is

cold and the bimetal plate is flexed downward,

keeping the air vent valve (A) open. This allows for

the rapid discharge of air through the vent (A) and

cold condensate through the orifice (B) when steam

is first supplied to the system.

2. Condensate Discharge

After the discharge of initial air and cold

condensate, the heat of the inflowing steam and

condensate cause the bimetal plate to flex upward,

closing the air vent valve (A). The rising

condensate level causes the float to rise due to

buoyancy, opening the orifice (B) and allowing

condensate to be discharged. The flexed bimetal

plate keeps the vent closed and will not open again

during normal operation.

3. Discharge of Large Quantities of Condensate

Increases in the condensate inflow rate cause the

condensate level in the trap to rise. The float

consequently rises and enlarges the opening of the

orifice (B), allowing more condensate to be

discharged. In this manner, continuous condensate

discharge occurs while the opening size of the

orifice varies depending on the condensate flow

rate.

4. Closed Position

When the condensate flow rate decreases, the float

falls, closing off the orifice (B) opening. A water

seal is maintained at all times over the orifice (B) to

prevent steam loss. On equipment where steam-

locking or air-binding tends to occur, system

integrity can be maintained by operating the

properly adjusted lock release valve.

Operational Check

A visual inspection of the following items should be done on a daily basis to

determine whether the product is operating properly or has failed. Periodically (at

least biannually) the operation should also be checked by using diagnostic

equipment, such as a stethoscope, thermometer, TLV Pocket TrapMan or TLV

TrapMan.

If the product should fail, it may cause damage to piping and equipment, resulting in

faulty or low quality products or losses due to steam leakage.

Normal

Condensate is discharged continuously, together with flash

steam, and the sound of flow can be heard. If there is very little

condensate, there is almost no sound of flow.

Blocked

(Discharge Impossible)

No condensate is discharged. The product is quiet and makes

no noise, and the surface temperature of the product is low.

Blowing

Live steam continually flows from the outlet and there is a

continuous metallic sound.

Steam Leakage

Live steam is discharged through the trap outlet together with

condensate, accompanied by a high-pitched sound.

(When conducting a visual inspection, flash steam is sometimes mistaken for steam leakage. For

this reason, the use of a steam trap diagnostic instrument [TLV: TrapMan] in conjunction with the

visual inspection is highly recommended.)
