Embodiment Construction

[0033] Figure 1 to Figure 3 One embodiment of the fluid control valve device for a hot water mixing faucet of the present invention is shown.

[0034] In these drawings, reference numeral 1 is a fluid control valve device for a hot water mixing faucet as a mixing valve built in a faucet body (not shown) of a mixing faucet, and includes a substantially cylindrical body 10 as a whole. On the lower side of the main body 10 , a cold water inlet 2 and a hot water inlet 3 through which cold water and hot water flow in are sequentially arranged along the axis direction of the main body 10 from the outer side of the outer peripheral direction of the main body 10 . In addition, a mixed water outlet 4 that discharges water (mixed water) toward the axial direction is provided at the lowermost portion of the main body 10 .

[0035] Such as figure 1 , figure 2 As shown in (a), (b), and (c), the reference numeral 20 is disposed in the main body 10 so as to be movable in the axial direc...

Abstract

A fluid control valve device for a hot water combination faucet is provided with: a cylindrical valve body (20) disposed inside a main body (10) so as to be movable in the axial direction; a temperature-sensing spring (30), which is disposed inside said cylindrical valve body (20) and is for biasing the cylindrical valve body (20) in the direction for increasing the amount of opening of the waterinlet (2); and a spring-receiving part (21), which is integrally connected to the cylindrical valve body (20) and is for supporting the free end of the temperature-sensing spring (30). Additionally, one end of the main body (10) is configured as a mixing chamber provided on the mixed water outlet (24) end for mixing hot water with water and discharging same, and the other end has an adjustment screw member (34) provided on the upper end of the main body (10) so as to allow adjustment of screw engagement, and a valve shaft (32) disposed so as to pass through the main body (10) and the cylindrical valve body (20). One end of said valve shaft (32) is connected and fixed to the spring-receiving part (21) and the other end is elastically connected and supported in the adjustment screw member (34).

Description

technical field [0001] The present invention relates to a fluid control valve device for a hot water mixing faucet suitable for use as a mixing valve for a hot water mixing faucet. The hot water supplied by the supply facility and the cold water supplied from the water pipe switch are taken out as mixed water (hot water) below a predetermined temperature. Background technique [0002] In the past, an automatic mixing valve used as an automatic mixing faucet is known, which mixes tap water with hot water from a hot water supply device, and when supplying mixed water at a predetermined temperature that can be appropriately changed by adjusting a screw, it uses a thermoelectric element as a sensor. Warm actuators are used to supply hot water at a certain temperature (refer to Patent Document 1). [0003] In addition, an automatic mixing faucet is conventionally known in which a heat-sensitive spring made of a shape-memory alloy coil spring is used instead of the above-mentione...
