Abstract
The present invention relates to a kind of zero-pressure and open the remote control float valve, comprise main valve and control valve, main valve comprises valve body, valve seat, valve disc, valve rod, valve gap; The main valve control room is communicated with control valve; Mainly be 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, and the pull bar lower end is fixedly connected with the valve rod upper end; The center of lower spring cup is passed the pull bar fixing seal and is installed on the valve gap; And cooperate 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.This zero-pressure opening device has overcome the deadweight of main valve valve disc and valve rod, makes the main valve valve disc be in normally open, is lower than under the 0.05Mpa state at 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.Be applicable to the control valve of water tank, pond, water tower level.
Description
Technical field
The present invention relates to valve field, specifically about a kind of remote control float valve.The present invention 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 objective of the invention is shortcoming, provide a kind of and be lower than under the 0.05Mpa state, still can bring into play the zero-pressure of control function and open the remote control float valve at main valve inlet pipeline pressure medium to the existing technology existence.
Technological scheme of the present invention 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.
Advantage of the present invention is to be provided with the zero-pressure opening device in the valve rod upper end; 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 a structural representation of the present invention.
Embodiment
Zero-pressure as shown in Figure 1 is opened the remote control float valve; Comprise main valve and control valve; Main valve comprises valve body 1, valve seat 18, valve disc 2, valve rod 17, valve gap 19, and valve disc 2 is fixedly connected with valve rod 17, is positioned at valve seat 18 outlet sides; Valve seat 18 centers are shaped on pilot hole, and valve rod 17 lower ends are movably arranged in this pilot hole.At diaphragm 16 centers, the sealing of diaphragm 16 edges is installed between valve body 1 and the valve gap 19 valve rod 17 by mounting disc 15 sealing and fixing, constitutes main valve control room 4 between diaphragm 16 and the valve gap 19, and this main valve control room 4 is communicated with control valve.Said control valve is made up of ball float pilot valve 5 and needle-valve 3; Ball float pilot valve 5 is installed on the controlling plumbing fixtures between main valve control room 4 and the water tank; Needle-valve 3 is installed on the intake pipe in main valve control room 4; Through the aperture of metering pin valve 3, when making by control object low water level, main valve control room 4 internal drainage speed are greater than water intake velocity.Mounting ball valve 6 on the controlling plumbing fixtures between ball float pilot valve 5 and the main valve control room 4.Valve rod 17 upper ends are provided with the zero-pressure opening device; This zero-pressure opening device is made up of pull bar 12, lower spring cup 10, upper spring seat 13, spring 11, the nut 14 of adjusting, and pull bar 12 lower ends are fixedly connected with valve rod 17 upper ends, and the center of lower spring cup 10 is passed pull bar 12 fixing seals and is installed on the valve gap 19; And cooperate with pull bar 12 motive sealings; Upper spring seat 13 is fixedly mounted on the pull bar 12 by the nut 14 of adjusting, and spring 11 is installed between lower spring cup 10 and the upper spring seat 13, through the adjusting position of nut 14 on pull bar 12 of adjusting; The elastic force of adjustment spring 11 makes valve disc 2 under the medium zero pressure, locate opening state.
