Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is local structure for amplifying schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of diaphragm type floater controlled valve, it is characterized in that, comprise valve body 1, diaphragm 2, control core 3, valve gap 5, support 6, driving block 9, ball lever 10 and float 11, described diaphragm 2 is located between valve body 1 and the valve gap 5, and described control core 3 passes the mesopore 16 of diaphragm 2, described control core 3 inside are provided with mandrel 4, this mandrel 4 is connected with support 6 by driving block 9, and described support 6 is in transmission connection with ball lever 10, and described float 11 is fixed on the ball lever 10.
The utility model also comprises for fixing control core 3 and the fixedly chock plug 7 that is connected mandrel 4 guiding and the valve seat 19 that is connected with diaphragm 2.Fixedly chock plug 7 is provided with weep hole 21.
The head of described control core 3, afterbody and middle part respectively have the hole, and wherein head bore 23 is connected with the cylindrical needle 22 of mandrel 4 head valve seats, and mandrel 4 afterbodys pass control core 3 tail holes, the cavity 17 that mider hole 20 is communicated with between diaphragm 2 and the valve gap 5.
Described valve body 1 is connected with valve gap 5 by the first screw 8.Described support 6 is provided with the first joint pin 12 and the cotter pin 13 of rotating for ball lever 10 with ball lever 10 joints.Described support 6 is connected with valve gap 5 by the second joint pin 15.Described float 11 is connected with ball lever 10 by the second screw 14.The mesopore 16 of described diaphragm 2 is provided with the sealing lip 18 for control core 3 face seals.
The utility model working principle is as follows:
Float 11 rises or descends with SEA LEVEL VARIATION, and when water level raise, float 11 rose, and drives ball lever 10 rotations and rises.Ball lever 10 rotates around the first joint pin 12.When water level descended, float 11 descended, and drove ball lever 10 and rotated decline, after ball lever 10 touches support 6, drove support 6 and rotated together around the second joint pin 15.Support 6 drives driving block 9 moving linearlies.Driving block 9 is fixed on the mandrel 4 with screw thread, and mandrel 4 is moving linearly also.When fluctuation appearred in water level, float 11 can be along ball lever 10 with SEA LEVEL VARIATION.
Diaphragm 2 is fixed between valve body 1 and the valve gap 5, and diaphragm 2 is made by elastic material.Sealed member for valve.Form a cavity 17 between diaphragm 2 and the valve gap 5.Control core 3 passes the mesopore 16 of diaphragm, and diaphragm 2 so diaphragm compressive deformation formula mesopore can slide along control core 3, is designed with sealing lip 18 owing to being elastic material on the diaphragm mesopore, and control core 3 surfaces form sealing.There is mandrel 4 control core 3 inside at control core 3 interior moving linearlies.Respectively there are two little valve seats at the two ends of mandrel 4.The head of control core 3 and tail end and middle part respectively have aperture.Head aperture and mandrel 4 end valve seat fitted seal.Mandrel 4 afterbodys pass control core 3 tail end apertures, and mandrel 4 step valve seats and aperture form sealing.Middle part aperture 20 links to each other valve cavity 17 with the control core inner.
When water level descended, float was in low level.Because float has weight, by the leverage of ball lever 10 with support 6, the power that acts on mandrel 4 is amplified, the head aperture that the head valve seat of mandrel 4 props up control core 3 forms sealing.Press water can not enter control core 3 and cavity 17 by aperture.But the press water of cavity can be discharged by the gap of the mesopore 20 on the control core 3 and control core 3 tail end apertures and mandrel 4.The pressure of cavity is close to barometric pressure.Diaphragm 2 is open under import hydraulic pressure.Diaphragm 2 breaks away from valve seat 19, and valve open is to the pond moisturizing.
Be in a high position when water level rises, float is in a high position.Because float has buoyancy, by the leverage of ball lever 10 with support 6, the power that acts on mandrel 4 is amplified, the afterbody aperture that the afterbody valve seat of mandrel 4 props up control core 3 forms sealing.Press water enters control core 3 and cavity 17 by 3 apertures of control core.The pressure of cavity is close to inlet pressure.Diaphragm 2 is pushed to valve body and valve seat 19 under import hydraulic pressure.Valve closing stops to the pond moisturizing.
