Abstract

The utility model relates to a vertical double-float automatic valve capable of automatically opening or closure rapidly, which is composed of a valve, a pipe piece, a main floating rod, an auxiliary floating rod, a clamping plate and a clip. When a liquid level falls, an auxiliary floating ball falls. A pull rope positioned between the lower parts of the auxiliary floating rod and the clip toggles a handle of the clip, and the clip head of the clip retreats from a lower concave mouth arranged on the middle section of the main floating rod; the main floating rod rapidly falls and drives a valve handle to twist in an anticlockwise direction by a connecting rod arranged on the upper end of the main floating rod to open the valve; the clip head of the clip enters an upper concave mouth of the main floating rod, and the main floating rod can not rise and the valve is kept to be opened. When the liquid level rises, the auxiliary floating rod rises and toggles the handle of the clip by a main lifting rope of the handle arranged on the upper end of the auxiliary floating rod, the handle of the clip retreats from the upper concave mouth to enable the main floating rod to rise rapidly, and the connecting rod of the auxiliary floating rod twists the valve handle in the clockwise direction to close the valve, and meanwhile, the clip head enters the lower concave mouth and the valve is kept to be closed. The utility model has the advantages of simple structure and convenient operation.

Description

Vertical pair of float self-acting valve

Affiliated technical field:

The utility model relates to a kind of liquid switch valve, especially vertical pair of float self-acting valve can opening automatically rapidly or close.

Background technique

At present, known liquid automatic switch valve has single-floating ball self-acting valve etc., this class single-floating ball self-acting valve can open or close automatically, and its deficiency is that the control ball float of such device is along with the slow rising of liquid level or decline and rise or descend, and and then opens or closes valve lentamente.Because the joint liquid time is slow, cause the too much wearing and tearing of sealing surface in the valve and be not closed completely, cause the leakage of liquid, also influenced the working life of sealing surface and whole valve.

Summary of the invention

In order to overcome existing single-floating ball self-acting valve some deficiency in the use, the utility model provides a kind of vertical pair of float self-acting valve, this vertical pair of float self-acting valve not only can be opened or be closed automatically, and this unlatching or close and to finish rapidly, reduced the friction time of valve inner seal liner and liquid, the working life of further improving Sealing and valve.

The technological scheme that its technical problem that solves the utility model adopts is: vertical pair of float self-acting valve is made up of valve, pipe fitting, main fly rod, secondary fly rod, clamping plate and several parts of clamp, and valve is positioned at pillar pipe fitting top; Main fly rod is positioned at valve and pillar pipe fitting side, and there is main ball float its lower end, and there is connecting rod its upper end, and connecting rod links to each other with the valve handle of valve by connecting nail, and there are upper notch and following recess in main fly rod middle part; Secondary fly rod is positioned at main fly rod side, and there is secondary ball float its lower end, and there is handle the upper end; Punch holder, middle clamp plate and die holder lay respectively at the upper, middle and lower portion of pillar pipe fitting, main fly rod and secondary fly rod, and clamp is positioned at one side of middle clamp plate, and both connect by the clamp bearing pin, and the clamp upper and lower has upper limit nail and lower limit nail; Clamp handle middle part and have secondary rope to connect between the spring carrying on the connecting rod, clamp handle below have stay cord to link to each other with fixing nail on the secondary fly rod, and its top has main rope to link to each other with handle on the secondary fly rod.When liquid level descends, secondary ball float is along with decline, stay cord is with the past lower plate of clamp handle, main fly rod under the effect of himself gravity rapidly toward gliding, the connecting rod of its upper end drives valve handle and reverses as inhour, and valve open, clamp head enter the upper notch at main fly rod middle part, prop up the rise of main fly rod, keep valve opening state; When liquid level rises, secondary fly rod is along with rising, with the past upper plate of the handle of clamp, the clamp head withdraws from upper notch to the handle of its upper end by main rope, and main fly rod rises rapidly under the promotion of main ball float buoyancy, and by its upper end connecting rod valve handle is reversed clockwise, valve closing, the clamp handle continues to rise by lifting of secondary rope and main rope by carrying spring, makes the clamp head enter down recess, prevent that main fly rod from falling, thereby keep closing of valve.

The beneficial effects of the utility model are to open or to close the friction time of minimizing liquid level and sealing surface, the working life of improving self-acting valve rapidly.Simple in structure, easy to use.
