Description

A kind of current autocontrol valve

Technical field

The utility model relates to a kind of valving, relates in particular to a kind of current autocontrol valve.

Background technique

General flow control valve is meant under the certain pressure difference, relies on the size that changes the resistance of restriction liquid to come the flow of control orifice, thereby regulates the valve class of actuator movement speed, can be widely used in multiple appliance arrangement.Existing common can be as being used for fish jar or other need control the system of fluid recloser, filtering system at the bottom of traditional operated by rotary motion fish jar, this need be used for overflow in fish jar bottom or overpunch; And because punching is easy to bring detonation, hidden danger such as leak, makes numerous aquarists have to abandon end filtering system and adopt the relatively poor top of filtering effect to filter or external filter vat mechanism; But this kind top filtering system had not only influenced attractive in appearance but also had been not easy to cleaning, and external filter vat more be not easy to place also can influence attractive in appearance.

The model utility content

At above defective, the utility model provides the current autocontrol valve that a kind of safe and reliable simple, easy to use, flow is big, need not to punch, can prevent overflow, and the technological means by the small flow controlling large flow that adopts realizes the bottom water flow circulating filtration.

For achieving the above object, the utility model is by the following technical solutions:

A kind of current autocontrol valve, comprise valve body, pressure intake pipe, small flow intake pipe, big flow intake pipe, speed limit valve small flow outlet pipe, float switch, the pressure intake pipe is arranged at the valve body outside and is divided into small flow intake pipe and big two branches of flow intake pipe, described valve inner is provided with the flexible sheet switch and by this switch body cavity is intercepted is big flow region and small flow zone, wherein the valve inner of a side connects big flow intake pipe, and big flow water outlet is offered in this part valve body bottom; The opposite side valve inner connects the small flow intake pipe, connects speed limit valve small flow outlet pipe on this part valve interior wall, and float switch is equipped with in this effluent pipe mouth outside.

Compared with prior art, the beneficial effect of current autocontrol valve described in the utility model is:

(1) safe and reliable: as to need not on fish jar, to burrow hidden danger such as not existing burrows brings detonation, leak; End cylinder has the duplicate protection switch, and water level can be regulated automatically, when having a power failure or during fault, can the automatic disconnection current, and keep water level in safety range, can prevent overflow;

(2) be convenient to install and use: only need a few minutes, whole system can be installed butt joint and finish, time saving and energy saving, can open and close in real time.

(3) flow is big: maximum water flow down can reach 20000L/H, and system regulates down water speed automatically according to the speed of water on the water pump.

Description of drawings

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the structure connection diagram of the described current autocontrol valve of the utility model embodiment.

Among the figure:

1, valve body; 2, pressure intake pipe; 3, small flow intake pipe; 4, big flow intake pipe; 5, speed limit valve small flow water intake; 6, flexible sheet switch; 7, speed limit valve small flow outlet pipe; 8, speed limit valve small flow water outlet; 9, float switch; 10, big flow water intake; 11, big flow water outlet.

Embodiment

As shown in Figure 1, the described current autocontrol valve of the utility model embodiment, comprise valve body 1, pressure intake pipe 2, small flow intake pipe 3, big flow intake pipe 4, speed limit valve small flow outlet pipe 7, float switch 9, pressure intake pipe 2 wherein is arranged at valve body 1 outside and is divided into small flow intake pipe 3 and big 4 two branches of flow intake pipe; Described valve body 1 inside is provided with the flexible sheet switch 6 that is close to big flow water intake 10 positions and by this switch valve body 1 inner chamber is intercepted and is divided into big flow region and small flow zone, be positioned at the big flow intake pipe 4 of a side valve body 1 inner connection of big flow region, be positioned at this regional valve body 1 bottom equally and offer big flow water outlet 11; Be positioned at the opposite side valve body 1 inner small flow intake pipe 3 that connects in small flow zone, this small flow intake pipe 3 is set to speed limit valve small flow water intake 5 with valve body 1 junction point, be positioned at equally and connect speed limit valve small flow outlet pipe 7 on this regional valve body 1 inwall, the outer end of this speed limit valve small flow outlet pipe 7 is set to speed limit valve small flow water outlet 8, and float switch 9 is equipped with in this water outlet outside.

The described current autocontrol valve of above the utility model embodiment, earlier valve body 1 is carried out forvacuum before use, on valve body 1, be provided with the pressure intake pipe 2 of small flow intake pipe 3 and big flow intake pipe 4, speed limit valve small flow water intake 5 is under the opened state at float switch 9 intakes, closure along with float switch 9, corresponding the reducing of water-outlet quantity of the water flow of speed limit valve small flow outlet pipe 7 and speed limit valve small flow water outlet 8, when the water-outlet quantity of the water flow of speed limit valve small flow outlet pipe 7 and speed limit valve small flow water outlet 8 during less than the inflow of speed limit valve small flow water intake 5, expansion meeting by hydraulic pressure is pushed flexible sheet switch 6 to water inlet that big flow water intake 10 also implements to close big flow intake pipe 4, can close fully during at float switch 9, thereby at this moment flexible sheet switch 6 also can thoroughly be pushed diaphragm to big flow water intake 10 by the hydraulic pressure of small flow intake pipe 3 simultaneously closing motion is closed and then finished to big flow water intake 10 to the water surface set; If when the ball float of float switch 9 is lower than the setting water surface, the automatic water outlet of speed limit valve small flow water outlet 8 meetings, can cause the water inlet of speed limit valve small flow water intake 5 by the water outlet of speed limit valve small flow water outlet 8, when the water-outlet quantity of speed limit valve small flow water outlet 8 during greater than the inflow of speed limit valve small flow water intake 5, pulling force by vacuum hydraulic pressure, the diaphragm of flexible sheet switch 6 can be drawn back, thereby realize big flow water intake 10 to increase flow of inlet water and water cycle fast.

Above embodiment is more preferably embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection domain of the present utility model.
