Abstract
The utility model relates to a zero-pressure opening remote control float valve, comprising a main valve and a control valve, wherein the main valve comprises a valve body, a valve seat, a valve rod and a valve cover, wherein a main valve control chamber is communicated with a control valve, and a zero-pressure opening device is arranged at the upper end of the valve rod and consists of a draw bar, a lower spring seat, an upper spring seat, a spring and a setting nut. The lower end of the draw bar is fixedly connected with the upper end of the valve rod, the center of the lower spring seat penetrates through the draw bar to be fixedly installed on the valve cover in a sealing manner and is matched with a movable seal of the draw bar, the upper ring seat is fixedly arranged on the draw bar by the setting nut, and the spring is arranged between the lower spring seat and the upper spring seat. In the utility model, the zero-pressure opening device overcomes the dead weight of a main valve disc and the valve rod to enable the main valve disc to be in a normally open state, and the zero-pressure opening remote control float valve can still supply water to an object needing water under the state that the medium pressure is lower than 0.05Mpa, so as to realize the functions of zero-pressure opening and low-pressure water supplying for the system, and the float valve is suitable for control valves for water tanks, water ponds and water tower levels.
Description
Technical field
The utility model relates to valve field, specifically about a kind of remote control float valve.The utility model is applicable to the control valve of water tank, pond, water tower level.
Background technique
Like the patent No. is the electric remote control float valve of ZL200920117933.3; Comprise main valve, solenoid pilot valve, float switch, controlling plumbing fixtures and control valve; Main valve comprises valve body, flap and control room; The control room is communicated with main valve inlet passage, solenoid pilot valve respectively through controlling plumbing fixtures, mainly is that float switch is a lifting structure, at solenoid pilot valve outlet serial connection one ball float pilot valve.Have that the water level control range is big, can regulate, the dead electricity advantage of control automatically.Be applicable to the water level control of water tower, water tank.Its major defect is that the flap of main valve is promoted to open by the pressure medium in the main valve inlet pipeline, and when the pressure medium in the main valve inlet pipeline was lower than 0.05Mpa, main valve just can't be opened, function out of hand.
Summary of the invention
The purpose of the utility model is the shortcoming that exists to existing technology, provides a kind of and is lower than under the 0.05Mpa state at main valve inlet pipeline pressure medium, still can bring into play the zero-pressure of control function and open the remote control float valve.
The technological scheme of the utility model comprises main valve and control valve, and main valve comprises valve body, valve seat, valve disc, valve rod, valve gap, and valve disc is fixedly connected with valve rod; Be positioned at the valve seat outlet side, at the diaphragm center, the diaphragm edge sealing is installed between valve body and the valve gap valve rod by the mounting disc sealing and fixing; Constitute the main valve control room between diaphragm and the valve gap, this main valve control room is communicated with control valve, mainly is that the valve rod upper end is provided with the zero-pressure opening device; This zero-pressure opening device is made up of pull bar, lower spring cup, upper spring seat, spring, the nut of adjusting; The pull bar lower end is fixedly connected with the valve rod upper end, and the center of lower spring cup is passed the pull bar fixing seal and is installed on the valve gap, and cooperates with the pull bar motive sealing; Upper spring seat is fixedly mounted on the pull bar by the nut of adjusting, and spring is installed between lower spring cup and the upper spring seat.
Preferably, lower spring cup is fixedly mounted on the positioning disk that is fixedly connected with the valve gap upper end by back of the body cap.
The utility model has the advantages that in the valve rod upper end and be provided with the zero-pressure opening device; This zero-pressure opening device has overcome the deadweight of main valve valve disc and valve rod; Make the main valve valve disc be in normally open; Be lower than under the 0.05Mpa state at main valve inlet pipeline pressure medium, still can supply water, the control function that the realization system zero presses off and opens, low pressure supplies water to the water supply object.
Description of drawings
Fig. 1 is the structural representation of the utility model.
