However, in the pressure release valve of Patent Document 1 mentioned above, when the rod is attached, the rotating support shaft presses the bearing in the radially outward direction in reverse to expand it.
Therefore, after the installation of the rod, the bearing expands or deforms, and there is a possibility that the bearing can no longer support the rotating fulcrum well

Embodiment Construction

[0027] Hereinafter, embodiments will be described using the drawings.

[0028] Figure 14 It is a simple diagram showing an example of the structure of the hot water storage tank provided with the pressure release valve provided in the hot water supply machine concerning embodiment of this invention. in Figure 14 Here, the drain pipe 44 is provided at the lower end of the hot water storage tank 42 provided with a heating mechanism (not shown) via an openable and closable drain valve 43. One end of a hot water supply outlet pipe 45 is connected to the upper end of the hot water storage tank 42, and the other end of the hot water supply outlet pipe 45 becomes a hot water supply pipe 46, which is a structure connected to a shower or bathtub not shown. The hot water supply pipe 46 is branched, and is connected to the external atmosphere opening port 48 via a release valve 47 that can be opened and closed by the operation of the lever 7.

[0029] In addition, the lever 7 is a manual l...

Abstract

The invention provides a valve making a housing well support a rod in the meantime that easiness of installing the rod via buckling is ensured and a hot water supplier with the valve. The valve is provided with: a housing with a flow inlet and a flow outlet for a liquid, a vavle body disposed in the housing and controlling flow of a flow body flowing from the flow inlet to the flow outlet, and a rod driving the valve body, the housing is provided with a supporting part supporting the rod in a mode of capablility of rotatoin, the rod is provided with a rotatoin part supported in a mode of rotation relative to the housing, a rotary supporting shaft is disposed at one party of a rotary part or a supporting part, a bearing of the rotary supporting shaft is disposed at the other part of the rotary part or the supporting part, the rotation part of the rod is constructed to be elastically deformable, so that when an external force acts in a direction along a rotation axis, the rotation part of the rod is displaced along the direction of the rotatoin axis, when the external froce is removed in a state that the rotation supporting shaft and the bearing are opposite, and the rotation part is in elastic deformation, with recovering of the rotation part, the rotation supporting shaft is supported on the bearing.

Description

Technical field [0001] The present invention relates to a valve and a hot water supply machine equipped with the valve. Background technique [0002] As a background art in this technical field, there is JP 2010-242903 A (Patent Document 1). The publication discloses the structure of the pressure release valve as follows: a valve seat coaxial with the diaphragm is provided, a valve body that can move in the axial direction with respect to the diaphragm and is energized by a spring to the valve seat is provided, and the primary pressure at the inlet The rise causes the diaphragm to move to the secondary side against the force of the pressing spring. When the primary pressure exceeds a predetermined pressure, one end of the shaft with the valve body abuts against the piston so that the valve body separates from the valve seat, thereby opening the valve. In this known example, the structure of the pressure release valve is also disclosed: when operating in the direction of raising ...
