Abstract
Long stroke valve of helical structure stopper fluid level control valve, including the disk seat, valve plug in the disk seat, the floater, the connecting rod, termination floater behind the connecting rod, swivel nut of its characterized in that disk seat rear end screw thread installation, swivel nut rear portion inner wall has reverse internal thread, there is reverse screw thread at the valve plug rear portion, valve plug rear portion and swivel nut rear portion threaded connection, equipartition several pinhole on the circumference of disk seat middle part, there is the bar pinhole valve plug front portion, the pin is inserted in disk seat pinhole and valve plug bar pinhole, the front end fixed connection of swivel nut rear end and connecting rod. The utility model discloses the valve plug produced the stroke of two same distances when the floater drove the rotation of swivel nut, and the stroke that just so makes the valve plug open has increased the one time than prior art, has increaseed the feed liquor volume of valve, and the fluid passage valve is unobstructed fast, has improved the work efficiency of valve.
Description
Technical field
This utility model relates to automatic liquid level control valve.
Background technology
The valve plug of valve plug helical structure autocontrol valve and valve base cavity threaded engagement, the other end of floating ball rod is connected with the external end head of valve plug, when ball float rises, ball float drives valve plug at valve base cavity rotary closing valve port by connecting rod, otherwise, when ball float declines, valve plug is at valve base cavity Unscrew valve port.The sealing force of this structure function close port on valve plug is big, close effective, closing late gate and can resist the pressure of high intensity, the liquid level of the valve particularly suitable high pressure of this structure automatically controls, such as water tank, solar water heater, toilet flush etc..The valve weak point that controls of this structure is exactly that the angle that rotates in a liquid of connecting rod that drives of ball float is less, normal conditions are at only 30～45 jiaos, and valve plug is less at the stroke of valve seat cavity, and it is little that this allows for that valve port opens, it is just slow that liquid enters the speed in casing, inefficiency.
Summary of the invention
The purpose of this utility model is in that to provide a kind of valve plug travel long, valve port opens bigger helical structure Long travel valve plug fluid level control valve, the technical solution of the utility model is as shown in drawings, a kind of helical structure Long travel valve plug fluid level control valve, including hollow type valve seat, valve plug in valve seat, ball float, connecting rod, rod rear end connects ball float, it is characterized in that valve seat rear end screw thread installs a swivel nut, swivel nut front inner wall has forward screw to threaded with valve seat rear end, swivel nut rear inside wall has reverse female thread, there is reverse thread at valve plug rear portion, valve plug rear portion is connected with swivel nut rear threads, uniform several pin-and-holes on circumference in the middle part of valve seat, there is bar shaped pin hole valve plug front portion, pin is inserted in valve seat pin-and-hole and valve plug bar shaped pin hole, swivel nut rear end is fixing with the front end of connecting rod to be connected.When this utility model ball float moves down, band movable snail sleeve rotates to valve port opposite direction, valve plug also moves to valve port opposite direction while moving with swivel nut under the helical rotation effect of swivel nut, the positive and negative screw thread of swivel nut rotates the stroke making valve plug produce two same distances simultaneously, the stroke relatively prior art that valve plug is opened thus is made to add one times, the distance of valve plug and valve port adds one times, increase the liquid inlet volume of valve, liquid is unobstructed quickly by valve, accelerate the feed liquor speed of valve, improve the work efficiency of valve.

Detailed description of the invention
Valve seat 1 rear end screw thread installs swivel nut 3, and swivel nut 3 and connecting rod 5 are fixed by engaging tooth structure, adjusts ball float position when engaging tooth structure is easily installed.Uniform 6 pin-and-holes 10 on circumference in the middle part of valve seat 1, pin 2, through the bar shaped pin hole 11 of pin-and-hole 10 and valve plug 4, makes valve plug 4 be enclosed within pin 2 and moves in valve seat 1 for guide rail with pin 2.The present embodiment swivel nut 3 helical pitch 44 millimeters, ball float 7 is by being raised up to landing drivening rod 5 hard-over 30, and two haul distances of valve plug are 44 × 30/360 × 2=7.34 millimeter.The present embodiment is applicable to toilet flush altitude valve.
