Description

  The present invention relates to a hot water supply / air heating apparatus including a header with a heat operated valve for heating.

  However, in this conventional apparatus, a seal with a symbol identifying the circuit number of each thermal valve is directly attached to the header with a thermal valve for heating. Adhering the seal to the header with valve is time-consuming, and during maintenance such as replacing only some of the thermal valves with new ones due to malfunction of the thermal valves, a circuit is added to the newly replaced thermal valve. The symbol for identifying the number also required a sticker to be attached, and the maintainability was poor.

  In order to solve the above problems, the present invention has a collecting pipe that rises upward on one end side, and a plurality of thermal valves provided sequentially in a substantially horizontal direction on the other end side. In the hot water supply and heating apparatus provided on the pipe connection plate in which the connection ports connected to the external piping are concentrated, the header with the heating thermal valve having a configuration in which the connection port for heating is provided below, Cover at least the upper surface and the front surface of the header with a thermal valve for heating with a drip-proof cover made of a transparent resin having a cutout hole that engages with the collecting pipe on one end side, and the heat of the front surface of the drip-proof cover. A symbol for identifying the circuit number of each thermal valve was written at a position corresponding to the valve.

  Further, a sticker on which a symbol for identifying a circuit number is displayed at a corresponding position of the drip-proof cover.

  According to the present invention, the relative position between the drip-proof cover and the header with the thermal valve for heating is regulated by the engagement between the notch hole and the collecting pipe, and the position of the circuit number of each thermal valve and each thermal valve. The position of the valve can be easily aligned, the circuit number of the heating pipe connected to each thermal valve can be easily identified, and even during maintenance such as replacement of the thermal valve, Since it is only necessary to attach the drip-proof cover that has been used, the maintainability can be improved.
