Abstract

A low water sensor testing device having an initial piping unit connected to a hot water boiler and also connected to a first three way purge valve unit, which valve unit is, in turn, connected to a T-shaped piping unit and affixed within the stem portion of which there is a low water level sensor unit with the T-shaped piping unit being further connected to a second three way purge valve unit, wholly equivalent to the first valve unit, with the second valve unit being connected to an adapter unit, in turn, also connected to outflow piping carrying boiler heated water via outflow piping to the heating system of a residential or commercial structure.

Claims

1. A low water sensor testing device, comprising:

a. an initial piping unit;

b. said initial piping unit being made up of a hollow, elongated ancillary piping component, a hollow elbow shaped fitting component and a hollow elongated first piping component;

c. said ancillary piping component having an externally threaded first end segment and an externally threaded second end segment;

d. said elbow shaped fitting component having internal threading within a first end segment thereof;

e. said elbow shaped fitting component having internal threading within a second end segment thereof;

f. said first piping component having an externally threaded first end segment and an externally threaded second end segment;

g. said second end segment of said ancillary piping component being threadably connected within said first end segment of said elbow shaped fitting component;

h. said first end segment of said first piping component being threadably connected within said second end segment of said elbow shaped fitting component;

i. a first three way purge fluid isolation valve unit;

j. an internally threaded first end cavity portion of said first valve unit;

k. said second end segment of said first piping component being threadably connected within said first end cavity portion of said first valve unit;

l. an internally threaded second end cavity portion of said first valve unit;

m. a T-shaped piping unit;

n. a hollow crossbar portion of said T-shaped piping unit;

o. an externally threaded first end segment of said crossbar portion;

p. said externally threaded first end segment of said crossbar portion being threadably connected within said second end cavity portion of said first valve unit;

q. an externally threaded second end segment of said crossbar portion;

r. a partially hollow stem portion of said T-shaped piping unit;

s. a through hole in said crossbar portion with a clearance sufficient to accept an elongated cylindrically shaped, externally threaded sensor unit;

t. a partially hollow stem portion of said T-shaped piping unit;

u. first affixation means for conjoining said stem portion to said crossbar portion at a locus of said through hole;

v. a solid base section of said stem portion;

w. an elongated internally threaded through hole within said base section with a clearance sufficient to accept an elongated, cylindrically shaped, externally threaded sensor unit;

x. a second three way purge fluid isolation valve unit;

y. an internally threaded first end cavity portion of said second valve unit;

z. an internally threaded second end cavity portion of said second valve unit;

aa. said second end segment of said crossbar portion being threadably connected within said second end cavity portion of said second valve unit;

bb. a hollow adapter unit;

cc. an externally threaded first end portion of said adapter unit;

dd. said first end portion of said adapter unit being threadably connected within said first end cavity portion of said second valve unit;

ee. a hollow second end portion of said adapter unit;

ff. second affixation means for conjoining a proximal end portion of outflow piping to inner walling of said hollow second end portion of said adapter unit, and;

gg. said externally threaded first end segment of said ancillary piping component being threadably connected to an internally threaded hole in a lateral side of a hot water boiler unit.

2. The low water sensor testing device of claim 1, whereby said first affixation means is a solder material.

3. The low water sensor testing device of claim 1, whereby said first affixation means is a weld.

4. The low water sensor testing device of claim 1, whereby said second affixation means is a solder material.

5. The low water sensor testing device of claim 1, whereby said second affixation means is a weld.

6. The low water sensor testing device of claim 1, whereby said second affixation means is a press fitted connection featuring an O-ring unit fitted within said hollow second end portion of said adapter unit.

7. A low water sensor testing device, comprising:

a. an initial piping unit;

b. said initial piping unit being made up of a hollow elongated first piping component;

c. said first piping component having an externally threaded first end segment and an externally threaded second end segment;

d. a first three way purge fluid isolation valve unit;

e. an internally threaded first end cavity portion of said first valve unit;

f. said second end segment of said first piping component being threadably connected within said first end cavity portion of said first valve unit;

g. an internally threaded second end cavity portion of said first valve unit;

h. a T-shaped piping unit;

i. a hollow crossbar portion of said T-shaped piping unit;

j. an externally threaded first end segment of said crossbar portion;

k. said externally threaded first end segment of said crossbar portion being threadably connected within said second end cavity portion of said first valve unit;

l. an externally threaded second end segment of said crossbar portion;

m. a partially hollow stem portion of said T-shaped piping unit;

n. a through hole in said crossbar portion with a clearance sufficient to accept an elongated cylindrically shaped, externally threaded sensor unit;

o. a partially hollow stem portion of said T-shaped piping unit;

p. first affixation means for conjoining said stem portion to said crossbar portion at a locus of said through hole;

q. a solid base section of said stem portion;

r. an elongated internally threaded through hole within said base section with a clearance sufficient to accept an elongated, cylindrically shaped, externally threaded sensor unit;

s. a second three way purge fluid isolation valve unit;

t. an internally threaded first end cavity portion of said second valve unit;

u. an internally threaded second end cavity portion of said second valve unit;
