Embodiment Construction

[0106] Embodiments of the present invention will be described below with reference to the drawings.

[0107] In FIG. 1 , 10 is a valve device with a pilot output and stop water and flow regulation, and 12 is a faucet with the pilot output and stop water and flow regulation valve device 10 .

[0108] 14 is the output water pipe of water tap 12, and its front end has output water port, carries out output water from this output water port.

[0109] 16 and 18 are the main waterway of the valve device 10 for pilot output and blocking water and flow regulation, that is, the inflow waterway of the primary side and the outflow waterway of the secondary side of the main waterway of the faucet 12 . 20 is a main valve constituted by a diaphragm valve provided on the main waterway.

[0110] The main valve 20 is composed of a hard main valve body 22 and a rubber diaphragm 24 held by it.

[0111] The main valve 20 can move forward and backward relative to the main valve seat 25 in the up ...

Abstract

The present invention provides a pilot type water discharging / stopping and flow regulating valve capable of performing both the discharging / stopping of water and the regulation of flow by light operations and, once the flow is regulated, discharging the water at a pre-regulated specified flow in the next water discharge even if the water is stopped. The pilot type water discharging / stopping and flow regulating valve (10) comprises a main valve (20), a back pressure chamber (26), an introducing small hole (28), a pilot water channel (30), and a flow regulating mechanism. The flow of the main water channel is regulated by advancing and retreating the main valve (20) following the advancement and retreat of a pilot valve (34). The valve further comprises a water discharging / stopping switching mechanism switching between the discharging and stopping of water by advancing and retreating the pilot valve (34) between a water discharge position and a water stop position. Furthermore, the flow regulating mechanism is formed to maintain the flow regulating position of the pilot valve (34) at a previously regulated flow regulating position when the pilot valve (34) performs the water discharge operation after performing the water stop operation by the water discharging / stopping switching mechanism.

Description

technical field [0001] The present invention relates to a pilot type output and stop water and flow adjustment valve device that uses the opening control of the guide waterway to output and stop water and flow adjustment; When the water is output, the pilot output of water can be output according to the pre-adjusted desired flow rate and the valve device for preventing water and flow adjustment. Background technique [0002] In the past, various options were available as faucets. When these faucets move the main valve that changes the opening degree of the main waterway forward and backward in the direction of approaching and separating from the main valve seat, a large force is required, and there is a problem that the operation is laborious. [0003] As a device to ease the operation of the faucet, the pilot output and the valve device that prevents water and flow adjustment are considered, that is, a pilot valve is built in the faucet by moving the pilot valve forward an...
