Abstract
The utility model is a high-pressure float valve. A water inlet pipe and a water outlet pipe are arranged in a closed valve chamber in the way of being vertical to each other. A holed rubber gasket divides the valve chamber into an upper chamber and a lower chamber. A valve cover is provided with a discharge hole and a forwards-closed single-way valve reed is arranged in the discharge hole. A central rod is connected with a control arm. The left end of the control arm is connected with the valve cover via a hinge and the right end is connected with floats. A spring is arranged between the control arm and the valve cover. With two floats, the valve can be controlled to let water in when the water level is low and to be closed when the water level is high. With one float, the control is the same with a conventional float valve. The high-pressure valve is simple in the structure, reliable in the seal and accurate in the control and can control a plurality of water levels, so the valve is provided with a very good market prospect.
Description
Technical field
The utility model relates to a kind of control valve, the particularly a kind of multi-functional float valve that can control two position.
Background technique
Known on the market at present float valve is the tin bronze manufacturing, because working principle has determined floating ball diameter big, lever length is long, cost height, and Sealing rapid wear, and working life is shorter.Chinese patent 200320127309.4 discloses a kind of " fluid level control valve ", it adopts the hydraulic self-locking sealing configuration, thereby can change the opening and closing of the variation control liquid level valve of valve pocket internal pressure with minimum control force, it is reliable to be active in one's movements, but exist structure complicated, be difficult for repairing, can only control deficiencies such as a kind of water level.
Summary of the invention
The utility model discloses a kind of float valve, utilize hydraulic self-locking sealing in the valve, under spring and ball float interaction, liquid level is carried out various control, make the function of float valve obtain expansion without electric energy.
The technological scheme of float valve technical solution problem described in the utility model is: intake pipe is vertical with outlet pipe in airtight valve pocket is provided with, sealing gasket is divided into two Room and topped suitable for reading in outlet pipe up and down with valve pocket, there is an equalizing orifice to be communicated with two Room up and down on the sealing gasket, one relief hole is arranged at top, last chamber, be equipped with the forward check valve sheet of sealing in the hole, the connecting rod that the valve block central vertical makes progress is connected with control arm on the valve top cover, bearing on control arm left end and the top cover is through latch hinge knot, be equipped with spring between control arm upper-end surface, middle part and the top cover, the control arm right-hand member is connected as angle adjustable with band bar ball float.
The utility model compared with prior art beneficial effect is: simple in structure, and precise control, reliable operation, good airproof performance can bear elevated pressures, and the multiple water level of may command assembles easy to maintenance.

Embodiment
Below in conjunction with accompanying drawing structure of the present utility model and working principle are described in further detail.
Described float valve, the valve pocket of forming sealing by valve body (1) and valve gap (2), water intake (15) communicates with valve pocket, water outlet (10) tubulose and the vertical setting of water intake (15), sealing gasket (3) is positioned between valve gap (2) and the valve body (1), valve pocket is divided into two Room, sealing is lined with equalizing orifice (8) and is communicated with chamber up and down, sealing gasket is provided with relief hole (23) and is communicated with atmosphere, sealing gasket is provided with strengthens valve block (22), valve gap has discharge orifice (19), is equipped with the one-way valve of forward closing (9) of band connecting rod (4) in the discharge orifice (19), and one-way valve (9) is provided with seal ring (18), discharge orifice (19) top is provided with water retaining ring (14), be arranged vertically leak-off pipe (13) with discharge orifice (19), valve gap (2) is provided with bearing (11), and control arm (5) is hinged through latch (20) and bearing (11), one-way valve is fixed in the fixture block (21) on the control arm, come off with in preventing to use, valve gap is connected with screw thread or screw with valve body, also can ultrasonic welding.Control arm upper-end surface and valve gap are equipped with spring, and the control arm right-hand member is connected as angle adjustable with ball lever (5).
Embodiment 1 adopts two ball floats, pressure spring is provided with along the control arm axis, left end places on the rotating spring seat of valve gap upper bracket, when valve is static because the spring tension control arm can depart from the axis that spring overlaps with control arm, constitute the structure of a bistable state, this moment, control arm kept a kind of stable state.Under this state, when one-way valve (9) moved down and opens discharge orifice (19) and destroyed the valve pocket balance, sealing gasket moved on (3), and water outlet is opened, and ball valve is opened water outlet.When rising, water level contacts upper floating ball (7), buoyancy is through ball lever (6), control arm (5) pressure spring, enter another stable state again after the axis that process overlaps is up, one-way valve moves synchronously simultaneously, forward closes discharge orifice (19) under hydraulic pressure, and the intake pipe press water makes the strong balance of two constant pressures up and down through equalizing orifice (8), but because of last cavity area greater than cavity of resorption water outlet area, thereby generation pressure reduction, sealing gasket (3) moves down topped water outlet, closes water valve and keeps stable state.If this moment is drawdown, the quality of upper floating ball (7) and ball lever (6) can not be enough to overcome spring tension, valve keeps and cuts out, when water level continues to reduce, have only when the essentially identical ball float (17) down of proportion and water and surface quality partly when the line that is flexible coupling (16), ball lever (6), control arm (5) overcome spring tension and press water to the making a concerted effort of one-way valve, spring axis is replied and is departed from coincidence, and earial drainage forms, valve is opened again, goes round and begins again.
As previously mentioned, the utility model float valve has reached the low level water inlet, the effect that high water level is closed.Embodiment 2 adopts single upper floating ball (7), elastic spring (12) to be provided with, should guarantee elastic spring (12 pulling force through control arm act on power on the one-way valve greater than press water to the one-way valve applied pressure, guarantee discharge orifice (19) unlatching, destructive valve is two Room balances up and down, and water valve often leaves, and have only when the water level rising, the buoyancy of upper floating ball (7) has overcome spring tension and has forward closed discharge orifice (19), ball valve is closed, and water level reduces valve to be opened again, goes round and begins again.
This example then can only the little variation of control water level, keeps water level to be controlled in the certain height scope.
