Fig. 1 is the utility model embodiment's structural representation.
In figure: 1-valve body of main valve, 2-lumen control room, 3-main valve valve seat, 4-main valve flap, 5-lumen inlet throttle hole, 6-lumen outlet throttling hole, 7-small ball, the float ball guided valve body of 8-, 9-bearing pin, 10-lever, the float ball guided valve flap of 11-, 12-spherical type head slip-knot bar, 13-ball float, 14-main spring, 15-O type circle, 16-seal ring, 17-handle.
Embodiment
As shown in Figure 1, a kind of direct current piston type guide float valve, comprise main valve, small ball 7 and float ball guided valve, the control end of described main valve connects one end of small ball 7, the other end of described small ball 7 connects float ball guided valve, in described valve body of main valve 1, be provided with lumen control room 2, in 2 openings of described lumen control room, be provided with the main valve flap 4 matching with main valve valve seat 3 in outer end, described main valve flap 4 middle parts offer the lumen inlet throttle hole 5 of leading to lumen control room 2, described lumen control room 2 offers the lumen outlet throttling hole 6 of leading to small ball 7, described float ball guided valve body 8 is hinged with lever 10 by bearing pin 9, the galianconism end of described lever 10 stretches in the draw-in groove of float ball guided valve flap 11, the long arm end of described lever 10 is connected with ball float 13 by spherical type head slip-knot bar 12.
In the present embodiment, described main valve valve seat 3 is installed in the entrance point of valve body of main valve 1, described main valve flap 4 the inners are connected with lumen control room 2 by main spring 14, the outer side wall of described main valve flap 4 is sealed and matched by O type circle 15 and the madial wall in lumen control room 2, and the front end of described main valve flap 4 is provided with the seal ring 16 that can be sealed and matched with main valve valve seat 3.Described small ball 7 and float ball guided valve are in normally open, and described small ball 7 is provided with the handle 17 of manual opening-closing operation, and small ball 7 can be directly manual, and keying small ball 7 drives the keying of main valve.
In the present embodiment, the structural feature of this direct current piston type guide float valve is as follows: (1) valve body of main valve 1 has adopted full tunnel, direct current type, airflow design, and loss of head is little, and good energy-conserving effect has guaranteed that this valve flow is large, operates steadily, noise is low.(2) use Lever type connecting rod ball float, the buoyancy transmission of ball float 13 is doubled and redoubled, increased the sealing force of float ball guided valve, jointing adopts spherical type head slip-knot bar 12 to connect, and makes the ball float 13 of float ball guided valve transmit stable equilibrium's the power of closing; Coordinate float ball guided valve flap 11 stable drives, solve existing float valve comprehensively and be subject to the volatile effect phenomenon of force unbalance because of flap, guarantee the functional reliability of float ball guided valve.(3) close tightly reliably; Main valve sealing adopts rubber seal ring sealing, closes power and is automatically formed by main valve lumen control room 2, keeps the suitable power of closing, and sealing life and reliability are high; Easy to operate, without separately joining automatical control system for valve, valve changes and opens and closes automatically with liquid level height.
In the present embodiment, the working principle of this direct current piston type guide float valve is as follows: when valve feeds water from entrance point, because small ball 7, float ball guided valve are often opened, the lumen inlet throttle hole 5 that current flow through in main valve flap 4 enters lumen control room 2, and the water in main valve lumen control room 2 flows out through small ball 7 and float ball guided valve.The aperture of float ball guided valve is greater than the long-pending aperture of flow section in lumen inlet throttle hole 5, and the water outlet drain discharge in main valve lumen control room 2 is greater than flow of inlet water, and therefore lumen control room 2 pressure decreaseds flow to the outlet end of main valve through guide's float valve.Main valve inlet pressure is greater than lumen control room 2 pressure, automatically opens main valve flap 4 and supplies water to outlet end, and main valve is in full-gear, and water tower (pond) supplies water.When water level raises, ball float 13 is closed float ball guided valve by lever 10, and the water in main valve lumen control room 2 can not flow out, and boosts in lumen control room 2, promotes main spring 14 and main valve flap 4 and closes main valve, and water tower (pond) stops supplying water.After the pond water surface declines, float ball guided valve reopens, and main valve lumen control room 2 hydraulic pressure decline, and main valve is again opened and continued to supply water, and keeps the setting height of liquid level.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
