Disclosed are a rocker-arm-type graded faucet and a valve element thereof, the valve element comprising: a lower valve body (10); an upper valve body (20); a fixed seat (30) arranged to be non-translatable and has an unchanged distance relative to the lower valve body (10); a rocker arm (40) having a free end and a connection end and pivotally connected to the fixed seat (30), wherein the connection end of the rocker arm (40) is connected to the upper valve body (20), such that when the rocker arm (40) vertically swings relative to the fixed seat (30), the connection end of the rocker arm (40) drives the upper valve body (20) to translate back and forth relative to the lower valve body (10); a first stop matching portion arranged at the side of the fixed seat (30); and a stop matching portion I arranged at the side of the rocker arm (40), wherein when the rocker arm (40) vertically swings relative to the fixed seat (30), the stop matching portion I can cooperate with the first stop matching portion to enable the rocker arm (40) to temporarily stay at a first specific swing angular position relative to the fixed seat (30). The improved valve element is provided, such that a rocker-arm-type faucet capable of conveniently sensing and controlling the opening degree is provided, and the graded rocking-type faucet has a simple structure and a low manufacturing cost, and extremely conveniently achieves water conservation.

Provided by the present invention is a faucet water purifier, a control valve and a disk assembly for a faucet water purifier, which comprises a control valve and a filtering device, wherein the filtering device defines a first communicating opening, a second communicating opening and a third communicating opening, the control valve comprises a valve body and a valve core, wherein the valve body defines a valve cavity, a first opening, a second opening, a third opening, a fourth opening, a fifth opening, a raw water inlet and a draining opening, wherein the valve core is disposed inside the valve cavity, wherein the first opening is communicated with the first communicating opening of the filtering device, the second opening is communicated with the second communicating opening of the filtering device, the fourth opening is communicated with the third communicating opening of the filtering device, the third opening is communicated with a water outlet of the filtering device, and the raw water inlet of the valve body is adapted to be communicated with a raw water source.

A three-way flow dividing valve structure is provided, including a valve body, a water divider, a spring, and a switch handle. A water intake communicating with the water inlet is formed on the side wall of the flow dividing chamber. A first and second outlet holes respectively communicating with the water outlets are formed at the bottom of the flow dividing chamber. The water divider includes a water dividing shaft and a water dividing dish; the bottom of the water dividing shaft is connected to the water dividing dish in the flow dividing chamber. The water dividing dish has a water dividing hole movably communicating with the outlet holes. The top of the water dividing shaft protrudes from the valve body and is connected to the switch handle. Two ends of the spring abut against the water dividing dish and the bonnet respectively. The present disclosure can be operated effortlessly.

Check valve are disclosed having a primary seal and a secondary seal, where the primary and secondary seals resist movement of a fluid through the check valve, and the secondary seal can provide a backup seal in an instance where the check valve does not function as intended. The primary and secondary seals can be formed by first and second sealing ridges, respectively, and a valve body can be positioned within the check valve, between a valve support, the first sealing ridge, and a second sealing ridge. The valve body is configured to move relative to the first and second sealing ridges, and can have a position wherein a portion of the valve body is engaged against any of the first and second sealing ridges.

An adjustable Venturi tube is provided and includes a water outlet segment and a water inlet segment. The water outlet segment has a gas inlet space therein and includes a chamber, a water flow selector disposed on the chamber, and a gas inlet pipe. The chamber has a gas inlet opening and a plurality of liquid-gas exits, which are in spatial communication with the gas inlet space. The water flow selector has a plurality of selective channels respectively facing the liquid-gas exits. The water outlet segment has a space and a water channel that is in spatial communication with the space. The water inlet segment and the water flow selector are configured to be moved relative to each other so as to allow the space to selectively be in spatial communication with at least one of the selective channels through the water channel.

A selector control that is manually operable by a user for activating or deactivating a primary control or a secondary control. The selector control may include a first state for activating the primary control and deactivating the secondary control, a second state for activating the secondary control and deactivating the primary control, and a failsafe state for deactivating both the primary control and the secondary control. The selector control may be configured to maintain the second state independent of continuous user input being applied to the selector control, and configured to maintain the first state when continuous user input is applied to the selector control. The selector control is normally biased toward the failsafe state such that the selector control automatically selects the failsafe state when the user discontinues applying the user input for maintaining the first state. The selector control has particular application for use in controlling a boom of a work vehicle.

A locking mechanism for a valve handle has a slider arranged to slide back and forth in a slot in the valve handle, between a lock position, in which the slider engages with a stop on the valve body and an unlock position, in which the slider does not engage with a stop. The slider is formed in two parts, which are inserted from opposite sides of the slot and snap fit together. The slider has indicia to indicate whether the slider is in the lock or unlock position, and the slider is arranged so as to cover the fastener which attaches the valve handle to the valve body.
