Description

Self-contained power grasshopper

Technical field

The utility model relates to a kind of grasshopper.

Background technology

Float switch is mainly adopted in level control (LC) at present, with the float-type solenoid valve of power supply as kinetic energy, moves up and down as the float-ball type switch of power with ball float, and it all has the little characteristics of rate of water make-up.The float-type solenoid valve is by the moving up and down of float, and makes contact, and the lifting that forms the attraction valve rod in magnetic field comes the switching of control electromagnetic valve, advantage is to be active in one's movements, but limitation is big, must be to possess the condition that power supply is arranged, the structure relative complex is applicable to little rate of water make-up, Maintenance and Repair rate height.The float-ball type switch is to be moved up and down by ball float, utilizes the closed pass of lever principle, and its advantage is simple in structure, need not other kinetic energy conditions, but can only be applicable to little rate of water make-up.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and need not other kinetic energy conditions, and can carry out the self-contained power grasshopper of big rate of water make-up.

For achieving the above object, the self-contained power grasshopper that the utility model provides comprises body, water inlet pipe, filling pipe, Bypass hose, piston, T-valve, fly rod, ball float; Described piston is arranged in the body, and amplify water pressure as promoting its self-contained power that moves ahead simultaneously in chamber before and after piston and piston seal are divided into body, and control water inlet and water outlet, finishes the action of blocking water inlet; Described water inlet pipe, filling pipe are connected with the body ante-chamber respectively; Piston head and the interior corresponding coupling of water inlet pipe mouth of body ante-chamber; Described T-valve comprises triple-valve body, valve shaft, valve plate; Described triple-valve body has water inlet, freeing port, advances accent; This water inlet is connected with water inlet pipe by Bypass hose, advances accent and is connected with the body back cavity; Described valve plate is arranged in the triple-valve body, and connects by valve shaft and triple-valve body are movable mutually, changeable water inlet pipe with advance one group of passage of lumen, or advance the passage of lumen and drainpipe composition; Described fly rod one end is fixedlyed connected with valve shaft, and the other end is fixedlyed connected with ball float, and water is converted to the power that T-valve switches to the buoyancy of ball float, can adjust the position of ball float simultaneously as required.

Described piston seal is a waveform configuration, and sealing is leaked before can preventing, the water inlet of assurance body back cavity is tight as kinetoplast, and bellows seal simultaneously is convenient to seesaw.

As further improvement of the utility model, described fly rod is an adjustable structure, and fly rod is by fixed knot and active section is sheathed forms.

Further improve as of the present utility model, be installed with the bearing that matches with valve shaft in the described triple-valve body.

Described valve shaft is that flute profile cooperates with valve plate, is convenient to change the valve plate angle.

On the described valve shaft spring is set, coincide with compression axis, flute profile.

Advantage of the present utility model is, and is simple in structure, and three road valves of switching and use self-contained power need not power supply and other kinetic energy, and it is extensive therefore to have applicability, and rate of water make-up is big.Applicable to large pool, the place of control liquid level requirement is arranged, can play the control liquid level, the effect of conserve water.

Embodiment

As shown in Figure 1, the utility model comprises body 1, water inlet pipe 2, filling pipe 3, Bypass hose 4, piston 6, T-valve 5, fly rod 9, ball float 10; Described piston 6 is arranged in the body 1, chamber 11,12 before and after piston 6 and piston seal 8 are divided into body; Described water inlet pipe 2, filling pipe 3 are connected with body ante-chamber 11 respectively; Piston head 7 is corresponding with the water inlet pipe mouth 21 in the body ante-chamber 11;

As Fig. 2, shown in Figure 3, described T-valve 5 comprises triple-valve body 51, valve shaft 52, valve plate 53; Described triple-valve body has water inlet 54, freeing port 55, advances accent 56; This water inlet 54 is connected with water inlet pipe 2 by Bypass hose 4, advances accent 56 and is connected with body back cavity 12; Described valve plate 53 is arranged in the triple-valve body 51, and connects by valve shaft 52 and triple-valve body 51 are movable mutually; Described fly rod 9 one ends are fixedlyed connected with valve shaft 52, and the other end is fixedlyed connected with ball float 10.

Described piston seal 8 is a waveform configuration.

Described fly rod 9 is an adjustable structure, and fly rod 9 is by fixed knot 91 and active section 92 sheathed forming.

As shown in Figure 4, be installed with the bearing 57 that matches with valve shaft 52 in the described triple-valve body 51, described valve shaft 52 and valve plate 53 are provided with spring 58 for flute profile cooperates on the valve shaft 52.

When the needs moisturizing, referring to Fig. 5, liquid level decline in the pond, ball float 10 is descending, and fly rod 9 simultaneously descending drive valve shafts 52 and valve plate 53 actions are connected the drainpipe 55 of T-valve 5 and are advanced accent 56; Close T-valve water inlet pipe 54.After making piston 6 releases, the hydraulic pressure of water inlet pipe 2 is pushed open the piston head 7 of the mouth of pipe 21, reaches the into purpose of water.Water is flowed in the pond by water inlet pipe 2, filling pipe 3, finishes the moisturizing action.

When stopping moisturizing, as shown in Figure 6, when ball float 10 floats because of liquid level in the pond rises, fly rod 9 is because of leverage, make to drive valve shaft 52 and valve plate 53 actions, switch to water inlet 54 and advance accent 56 connections, back cavity 12 bodies that make current advance body 1 promote piston 6 reaches, piston head 7 is blocked water inlet pipe mouth 2, reaches to stop moisturizing.

When rising synchronously of demand liquid level upper and lower limit or decline, promptly the upper limit improves than the standard liquid level position, and lower limit also improves simultaneously, and the upper limit descends than the standard liquid level, and lower limit also descends.Can adopt the adjusting of adjustable fly rod 9, in active section 92 income fixed knots 91, shorten the length of adjustable fly rod 9 and implement, also can from triple-valve body 51, upwards wear adjustable fly rod 9 and regulate.Increase between demand liquid level bound or reduce highly increase between bound or minimizing be bound in opposite directions or inverted orientation.Can adopt the angle that changes T-valve 5 valve plates 53 and adjustable fly rod 9, promptly valve rod 9 tops are pulled upwardly, a flute profile be coincide throw off, and it is identical again by spring 58 effects with stem lower portion to put down valve rod 9 tops as required after the rotation, finishes angular transformation.
