Description

A kind of fluid level control valve

Technical field

The utility model relates to a kind of fluid level control valve.

Background technique

The fluid level control valve of existing market control liquid level need with supplementary equipment such as external ball float or ultrasonic wave controllers.Increase cost and be subject to again extraneous factor interference simultaneously, cause water tank spilling water.Ball float, because of water level fluctuations, cannot be closed in time; The electronic equipments such as ultrasonic wave controller disturb cannot normally work because of factors such as power failures.

Model utility content

In order to overcome the deficiencies in the prior art, primary and foremost purpose of the present utility model is to provide a kind of without the need to external ancillary equipment, and not by the fluid level control valve of extraneous factor interference, concrete scheme of the present utility model is as follows for achieving the above object:

A kind of fluid level control valve, comprises main valve, inlet ball valve, vent ball valve and Relief pilot valve;

Described inlet ball valve, vent ball valve are connected to input end, the output terminal of described main valve;

Described Relief pilot valve is also located at the output terminal of described main valve, and described Relief pilot valve is provided with for detecting liquid level with the PRESSURE PIPE of automatically opening.

Preferably, also comprise needle-valve, described needle-valve is located at described main valve input end.

The fluid level control valve that the utility model provides is that one accurately can control liquid level, without the need to installing the fluid level control valve of the supplementary equipment such as ball float or ultrasonic wave controller.

Accompanying drawing explanation

Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a application's part, does not form improper restriction of the present utility model, in the accompanying drawings:

Fig. 1 is the utility model example structure schematic diagram.

Embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.

As shown in Figure 1, a kind of fluid level control valve, comprises main valve 1, inlet ball valve 2, vent ball valve 6 and Relief pilot valve 4; Described inlet ball valve 2 is installed on inlet line, and vent ball valve 6 is installed on outlet line, makes its input end being connected to described main valve 1, output terminal, opens main valve 1 by the inlet ball valve 2 and vent ball valve 6 regulating main valve 1 pipe arrangement; Described Relief pilot valve 4 is also located at the output terminal of described main valve 1, and described Relief pilot valve 4 is provided with for detecting liquid level with the PRESSURE PIPE 5 of automatically opening, and Relief pilot valve 4 is by the highly automated unlatching of PRESSURE PIPE 5 induction level, thus control bound 1 open/close states.

As above-described embodiment improved scheme, also comprise needle-valve 3, described needle-valve 3 is located at described main valve 1 input end, the aperture and speed of opening main valve 1 valve is regulated by metering pin valve 3, Relief pilot valve 4 according to on-the-spot liquid level requirement, can set any engaging pressure, thus required control liquid level.

Above the technological scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and mode of execution, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, embodiment and application area all will change, and in sum, this description should not be construed as restriction of the present utility model.
