Embodiment
Below in conjunction with Figure of description, the concrete structure of large flow self-pressure type float valve of the present utility model is done to illustrate:
A large flow self-pressure type float valve, as shown in Figure 1, it comprises valve body 1, diaphragm valve core assembly 2 and floating ball component 3; Described valve body 1 comprises valve seat and valve gap; Described valve body 1 is provided with water intake 11, valve pocket and the water outlet 12 being communicated with successively; Described diaphragm valve core assembly 2 is arranged in described valve pocket, and described valve pocket was divided into sap cavity 13 and pressure pocket 14; The described sap cavity 13 of crossing is connected with described water intake 11 and described water outlet 12, for described diaphragm valve core assembly 2 provides the elastic component 4 of elastic force, is located in described pressure pocket 14; Described mistake in sap cavity 13 is provided with sealed mouth 15, and the bore of described water intake 11, described sealed mouth 15 and described water outlet 12 equates; Described floating ball component 3 comprises the fixed support 31 that is fixed on described valve body 1, is rotatably connected on the ball lever 32 on described fixed support 31 and is arranged on described ball lever 32 away from the ball float 33 of described fixed support 31 one end; The described aperture 21 that described diaphragm valve core assembly 2 is provided with in the aperture 21(the present embodiment that is communicated with described sap cavity 13 excessively and described pressure pocket 14 is arranged on the diaphragm of diaphragm valve core assembly 2); The water outlet with pressure release passage 51 is chewed 5 and is fixed on described valve body 1, and described pressure release passage 51 is connected with described pressure pocket 14; Described ball float 33 in the process moving up by be arranged on boss on described ball lever 32 321 promote seals 6 near described water outlet, chew that 5 directions move and shutoff described in pressure release passage 51.By adopting said structure, when valve body, the buoyancy that ball float 33 produces only need overcome the water pressure at pressure release passage 51 places, therefore can make float valve closing motion rapid, and good sealing effect.
Below the working procedure of the float valve in the present embodiment is elaborated: in use, float valve is loaded in water storage box, and the water intake of float valve 11 is connected with the intake pipe of water storage box, during anhydrous state, described diaphragm valve core assembly 2 is crossed the described sealed mouth 15 of sap cavity 13 under the effect of described elastic component 4 described in shutoff, now described ball float 33 naturally droops; During water inlet, water enters in described valve body 1 from described water intake 11, described diaphragm valve core assembly 2 moves down under Water Pressure, and compress described elastic component 4, and then water flows in water storage box through described sealed mouth 15 and the described water outlet 12 of crossing sap cavity 13, because the bore of described water intake 11, described sealed mouth 15 and described water outlet 12 is equal, so the water flow of the water intake 11 of flowing through, sealed mouth 15 and water outlet 12 equates.Therefore in addition, because described diaphragm valve core assembly 2 is provided with aperture 21, have a small amount of water by described aperture 21, and flow through described pressure pocket 14 and pressure release passage 51 flow in water storage box.When waterborne in water storage box is raised to certain water level, can promotes described ball float 33 and move up, and boss 321 on described ball lever 32 can promote described seal 6 to chew 5 directions near described water outlet, until block described pressure release passage 51; Subsequently, the water that continuation is entered by described aperture 21 can be full of described pressure pocket 14 and pressure release passage 51, and then rapidly described diaphragm valve core assembly 2 is upwards promoted and the described described sealed mouth 15 of crossing sap cavity 13 is blocked in the water pressure of described pressure pocket 14 interior generations and elastic force one same-action of described elastic component 4 generations, now current are truncated, and stop into water; At this moment, the water at described water intake 11 places is to be connected by aperture 21 with the water in pressure pocket 14 and pressure release passage 51, therefore the hydraulic pressure at water intake 11 places equates by force with the hydraulic pressure in pressure pocket 14 and pressure release passage 51 by force, so, relying on this " oneself presses oneself " is that self-pressure type structure just can guarantee the sealing effect of sealed mouth 15; When in water storage box, water level declines, ball float 33 also can move down, and 6 of described seals lose the thrust that described boss 321 provides, under the effect of valve body 1 interior hydraulic pressure, seal 6 can leave water outlet and chew 5, and the described sealed mouth 15 of crossing sap cavity 13 is opened immediately, continues subsequently water inlet.
In the present embodiment, the aperture of described aperture 21 is 1mm to 2mm, and preferred size is 1.5mm.
Described diaphragm valve core assembly 2 comprises the supporting element 22 of being located in described pressure pocket 14, and described supporting element 22 is provided with towards the supporting foot extending away from described sap cavity excessively 13 directions.By adopting this structure, when diaphragm valve core assembly 2 is subject to powerful water pressure, supporting foot can be against on the inwall of valve body 1, thereby breaks when the diaphragm that effectively prevents diaphragm valve core assembly 2 has been the crunch of sap cavity.
As shown in Figure 1, described water outlet in the present embodiment is chewed 5 outside and is provided with seal locating piece 7 in a tubular form, described seal 6 is located in described seal locating piece 7, the sidewall of described seal locating piece 7 is provided with water passage hole 71, and the water flowing out from described pressure release passage 51 like this can flow in water storage box through water passage hole 71.Spacing by adopting said structure described seal 6 can be carried out, and play leading role when described seal 6 moves, rational in infrastructure, using effect is good.
Described water outlet in the present embodiment is chewed 5 outer wall and is provided with outside thread, and the inwall of described seal locating piece 7 is provided with the internal thread being connected with described outside thread, by adopting this structure can be easily that seal locating piece 7 is fixing.
In the present embodiment, described fixed support 31 is provided with attachment hole 311 for being rotationally connected with described ball lever 32 and for described ball lever 32 is limited in to the spacing hole 312 that upper and lower moves up, by adopting this structure can make ball lever 32 and ball float 33 to move on above-below direction, and can not swing, thereby make the closing motion of float valve sensitiveer.
Described fixed support 31 in the present embodiment is circular tube shaped, is located at the outside of described seal locating piece 7, and fixing by described seal locating piece 7, by adopting this structure easily described fixed support 31 to be fixedly installed on described valve body 1.
Described attachment hole 311 in the present embodiment is circular port, and described spacing hole 312 is waist shaped hole.
Owing to comparing with the elastic component of other structure, spiral yarn shaped elastic component is more easily installed, and the using effect having had, so the described elastic component in the present embodiment 4 is spiral yarn shaped Compress Spring.
In the present embodiment, described ball float 33 is plastics hollow float, by adopting this structure can make the weight of ball float 33 greatly alleviate, thereby ball float 33 can be moved in time with SEA LEVEL VARIATION, guarantees the sensitivity of float valve closing motion.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all mode of executions.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
