Advantageously, as shown in Figures 1 to 7, pressing plate 32 is provided with the vent 302 staggering with port 301.Thus, when closed component 3 is opened intake and exhaust channel 102, can make air-flow rapid flow, be convenient to the use of intake and exhaust water valve 100.
Certainly, also pressing plate 32 can be arranged to not seal the shape of porting 105, make pressing plate 32 can seal port 301, and do not affect the circulation of air of intake and exhaust channel 102.
As shown in Figure 1, in embodiments more of the present utility model, the inwall of the porting 105 of valve body 1 is provided with breach (not shown), and the outer rim of closure member 31 is engaged in breach.Thus, improved the sealing of the outer rim of closure member 31 and the joint of valve body 1.And be convenient to the installation of closure member 31, improve the installation efficiency of closure member 31, be convenient to production and the assembling of intake and exhaust water valve 100, in addition, also make the appearance of intake and exhaust water valve 100 smooth.
Further, closure member 31 is flexible sheet or elasticity plain cushion.Thus, make the simple in structure of closure member 31, convenient formation and cost are low.
One of ordinary skill in the art will appreciate that the concrete form that the utility model does not limit closure member 31 limits, closure member 31 can also for of the prior art other can be under hydraulic drives QA element.
Advantageously, pressing plate 32 is connected with valve body 1 screw.Thus, make pressing plate 32 and valve body 1 stable connection, thereby improved connective stability and the join strength of pressing plate 32 with valve body 1.Thereby pressing plate 32 is pressed on closure member 31 on valve body 1.But also be convenient to the assembling of intake and exhaust water valve 100, enhance productivity.
Certainly, pressing plate 32 can also be bolted, welding, clamping, the mode such as bonding and valve body 1 link together.
What one of ordinary skill in the art will appreciate that is; above-mentioned is only specific embodiments more of the present utility model to the specific descriptions of closed component 3; the not restriction to the utility model protection domain; intake and exhaust water valve 100 of the present utility model can also have other structure and form; for example; the flange extend internally is set on the wall of porting 105, and through hole is set on flange, and intake and exhaust channel 102 interior arrange can be in the promotion of hydraulic pressure the floating block at this through hole of sealing.
As shown in Figure 1, in embodiments more of the present utility model, valve body 1 is provided with spring 41 and the Electromagnetic Drive part 42 for driving spool 2 to move to open position moving to closed position for normal promotion spool 2.In other words, intake and exhaust water valve 100 is normally closed solenoid valve.Thus, reduced the energy consumption of intake and exhaust water valve 100, energy-conserving and environment-protective, and make the control of intake and exhaust water valve 100 convenient and highly sensitive, be convenient to the quick switching of intake and exhaust water valve 100.
Particularly, as shown in Figure 1, on valve body 1, be also provided with valve core housing 43, valve core rod 44, seal ring 45, and Electromagnetic Drive part 42 comprises coil 46.The end of valve core rod 44 is connected with spool 2, and valve core rod 44 is set in valve core housing 43 along the vertical direction movably, and valve core housing 43 is connected with valve body 1, and seal ring 45 is located at the joint of valve core housing 43 and valve body 1.Coil 46 is located at valve core housing 43 outsides, and spring 41 is located in valve core housing 43, and one end of spring 41 is connected with valve core housing 43, and the other end of spring 41 is connected with valve core rod 44.Spring 41 often has downward promotion valve core rod 44 for making spool 2 power in the closed position, and will drive spool 2 to move to open position after coil 46 energisings.
One of ordinary skill in the art will appreciate that this intake and exhaust water valve 100 can also be normally open solenoid valve.Particularly, spring often promotes spool 2 and moves to open position, and will drive spool 2 to move to closed position after 42 energisings of Electromagnetic Drive part.
