Detailed Description

The technical solution of the present invention is further explained below with reference to the following examples.

The first embodiment is as follows:

this multi-functional valve key includes:

the key body 90100 is rectangular and columnar;

the exhaust valve key 90200, the exhaust valve key 90200 includes a round column 90201, the center of the round column 90201 is provided with a square blind hole I90202, and the exhaust valve key 90200 is arranged at one end of the key main body 90100;

the water injection valve key 90300, the water injection valve key 90300 includes a square block 90301, the center of the square block is provided with a second square blind hole 90302, and the water injection valve key 90300 is arranged in the middle of the key main body 90100;

the water flow sensor key 90400, water flow sensor key 90400 includes oblate piece 90401, oblate piece 90401 is located the other end of the key main part 90100 of relative discharge valve key 90200, oblate piece 90401 center is equipped with hexagon through-hole 90402.

Specifically, when the wall-mounted boiler is subjected to water replenishing operation, the water filling valve square switch 90-A-1 of the water filling valve 90-A is inserted into the square blind hole II 90302 of the water filling valve key 90300, and the key body 90100 is screwed to rotate the square switch 90-A-1, so that the water replenishing operation can be completed.

When the wall-mounted furnace is subjected to exhaust operation, the circular upright column 90201 of the exhaust valve key 90200 is inserted into the circular key hole 90-B-1 of the exhaust valve 90-B, the exhaust valve square switch 90-B-2 in the circular key hole 90-B-1 is inserted into the square blind hole I90201 of the exhaust valve key 90200, the exhaust operation can be completed by screwing the key body 90100, the stress point of the circular block of the water flow sensor key 90400 can be increased when the circular block is screwed, and the operation is convenient.

When the water flow sensor of the wall-mounted furnace is replaced, the water flow sensor can be disassembled and replaced by sleeving the hexagonal through hole 90402 of the water flow sensor key 90400 on the bolt 90-C-1 of the water flow sensor 90-C, screwing the key body and screwing out the bolt 90-C-1.

This multi-functional valve key integrates the valve key of three kinds of valves on a key, has reduced the instrument quantity that needs when the operation, has improved convenience and work efficiency.

Example two:

the difference between the second embodiment and the first embodiment is that the wider side 90100-1 of the key body 90100 is provided with a reinforcing rib 90102, and the reinforcing rib 90102 is a rectangular protrusion perpendicular to the wider side 90100-1 of the key body 90100.
