Description

Constant temperature valve body structure

Technical Field

The utility model relates to the technical field of thermostatic valves, in particular to a thermostatic valve body structure.

Background

Referring to fig. 1, a conventional thermostatic valve body generally includes a switching valve chamber 1 'and a thermostatic valve chamber 2' at both ends, and a first water inlet passage 3', a second water inlet passage 4', a water mixing passage 5', and at least one water outlet passage 6'; two water inlets of the constant temperature valve body are respectively communicated to the constant temperature valve cavity 2' through a first water inlet channel 3' and a second water inlet channel 4 '; the constant-temperature valve cavity 2' is communicated with the switching valve cavity 1' through the water mixing channel 5 '; the water inlet end of the water outlet channel 6 'is communicated with the switching valve cavity 1', and the water outlet end is used for being connected with a water outlet device such as a top shower, a hand shower, a bubbler and the like.

The existing part of constant temperature valve body is injection molded by plastic and other materials so as to achieve the purposes of convenient molding, cost control and the like. In the injection molding process, the switching valve cavity 1', the constant temperature valve cavity 2', the first water inlet channel 3', the second water inlet channel 4', the mixed water channel 5 'and the water outlet channel 6' are all formed through core pulling procedures, so that the axes of the structures are required to be arranged along the mold opening direction of the mold, the core pulling quality can be ensured, and each cavity with a corresponding shape is obtained. As can be seen from fig. 1, the water inlet adjacent to the thermostatic valve cavity 2' can be communicated to the thermostatic valve cavity 2' only through a shorter first water inlet channel 3', and the first water inlet channel 3' can be coaxially arranged with the water inlet and directly communicated to the thermostatic valve cavity 2', so that core pulling is not difficult to complete; the water inlet far away from the constant temperature valve cavity 2 'needs to be communicated to the constant temperature valve cavity 2' through a longer second water inlet channel 4', and the end part of the second water inlet channel 4' is connected to the water inlet (the two water inlets are arranged in the same direction to realize a water supply pipe communicated to a wall surface), and a core pulling port capable of pulling a core is not arranged in the axial direction, so that the core pulling difficulty is increased. The existing method is that a core-pulling port which is coaxially arranged with a second water inlet channel 4 'is arranged at the end part of a constant temperature valve body so as to realize core pulling of the second water inlet channel 4', and the core-pulling port is plugged after core pulling is completed; however, the second water inlet channel 4 'is further provided with a switching valve cavity 1' and a constant temperature valve cavity 2 'in the axial direction, and the switching valve cavity 1' and the constant temperature valve cavity 2 'cannot be reduced to the core-pulling port for the reason that the switching valve and the constant temperature valve are fixed fittings, so that the second water inlet channel 4' can only be deviated to the outer side of the constant temperature valve body (as in fig. 1, the second water inlet channel can be upwards deviated), the size of the constant temperature valve body can be increased, the constant temperature valve body is difficult to match with the shell of the constant temperature valve produced in the prior art, and meanwhile, the cost can be increased.
