Description
Technical field
The utility model relates to a kind of float valve that can control liquid level automatically.
Background technique
Float valve adopts Lever type ball float structure more at present, and it is formed by several critical piece structures such as valve body, piston, connecting rod and ball float, uses lever principle work.When liquid level was low, ball float reduced with liquid level, pulled outward by the piston in the connecting rod drive valve body of fixing ball float, made liquid enter container thereby open valve; When height and position that liquid level arrive to be set, ball float pushes away the piston in the valve body by connecting rod with the liquid level power that is produced that rises toward valve body in, thereby throttle down cuts off liquid stream, works so constantly with assurance automatic liquid supply and control liquid level in container.Such floating ball valve structure relative complex, cost is higher, and is easy to generate fault during actual the use.
The model utility content
The purpose of this utility model just is to provide a kind of simple in structure, convenient reliable float valve of control.
For achieving the above object, the utility model float valve is made up of connecting rod, valve shaft, valve body, spool, spring, cotton rope, ball float, valve shaft is connected with spool, be provided with spring between one end of valve shaft and the valve body, the valve shaft the other end is connected with the shaft hinge of connecting rod, one end of connecting rod is connected with the valve body hinge, connects cotton rope on the shaft of the other end, and cotton rope is connecting ball float.
At cotton rope and connecting rod joint liquid level regulator can be set as required, change the position height of ball float in container, thereby the unlatching of positioning control valve at various height, close, reach the purpose of control liquid level height by the length of regulating cotton rope.
This side of mounting spring can be provided with pressure regulating cover on valve body, is threaded between pressure regulating cover and valve body, and an end of spring withstands on the inboard of pressure regulating cover, the other end withstands on the spool, by screwing or unscrew pressure regulating cover, can adjust the pressure of spring to spool, guarantee the spool action accurately.For guaranteeing the valve shaft action accurately and reliably, be provided with a valve shaft seat at pressure regulating cover bottom centre place, valve shaft cooperates with valve shaft seat formation activity.
Sealing configuration between valve shaft and valve body can adopt packing box seal, also can adopt cup packing or other sealing configuration.
Adopt such structure,, directly control the switching of spool, thereby have simple in structure, the convenient reliable advantage of control, also reduced cost simultaneously effectively with the spring synergy because ball float directly acts on valve shaft by cotton rope, connecting rod.
When liquid level descends, after ball float drops to the tension cotton rope, can drive valve shaft by connecting rod and overcome spring force spool is opened, this moment, valve was in "open" state, the pressure regulating cover that is provided with can be adjusted the pressure of spring to spool, makes the pulling force of ball float just in time can overcome the resistance of spring; When liquid level rose, ball float rose and unclamps cotton rope, and the spring force effect is closed spool, and this moment, valve was in "off" state.
Description of drawings
Fig. 1 is the structural representation of the utility model float valve.
In the accompanying drawing:
1 connecting rod; 2 liquid level regulators; 3 valve shafts; 4 seal rings;
5 valve bodies; 6 spools; 7 springs; 8 pressure regulating covers;
9 cotton ropes; 10 ball floats; 11 intermediate plates; 12 pressure rings;
13 valve shaft seats.
Embodiment
Fig. 1 has provided the embodiment of the utility model float valve, it is by connecting rod 1, liquid level regulator 2, valve shaft 3, seal ring 4, valve body 5, spool 6, spring 7, pressure regulating cover 8, cotton rope 9, ball float 10 is formed, valve shaft 3 is connected with spool 6, be provided with spring 7 between one end of valve shaft 3 and the valve body 5, valve shaft 3 the other ends are connected with the shaft hinge of connecting rod 1, one end of connecting rod 1 is connected with valve body 5 hinges, connect cotton rope 9 on the shaft of the other end, cotton rope 9 is connecting ball float 10, cotton rope 9 is provided with liquid level regulator 2 with connecting rod 1 joint, this side of mounting spring 7 is provided with pressure regulating cover 8 on valve body 5, pressure regulating cover 8 is threaded with 5 of valve bodies, one end of spring 7 withstands on the inboard of pressure regulating cover 8, and the other end withstands on the spool 6.
When liquid level descends, after ball float 10 drops to tension cotton rope 9, can drive the spring force that valve shaft 3 overcomes spring 7 by connecting rod 1 opens spool 6, this moment, valve was in "open" state, the pressure regulating cover 8 that is provided with can be adjusted the pressure of 7 pairs of spools 6 of spring, make the pulling force of ball float 10 just in time can overcome the resistance of spring 7, liquid can enter container through valve; When liquid level rose, ball float 10 rose and unclamps cotton rope 9, and the spring force effect of spring 7 is closed spool 6, and this moment, valve was in "off" state, and liquid is cut off and can't enters container.
Adopt cotton rope 9 to connect ball float 10, it mainly is the flexibility of utilizing cotton rope 9, like this when liquid level rises, the buoyancy of ball float 10 can not act on connecting rod 1, buoyancy can not be delivered to the sealing surface of spool 6 and valve body 5 by connecting rod 1 yet like this, thereby makes the sealing surface of joint reduce the extra stressed probability that produces fault that yet reduced.
Joint at cotton rope 9 and connecting rod 1 can be provided with liquid level regulator 2 as required, change the position height of ball float 10 in container by the length of regulating cotton rope 9, thereby the unlatching of positioning control valve at various height, close, reach the purpose of control liquid level height.
This side of mounting spring 7 is provided with pressure regulating cover 8 on valve body 5, pressure regulating cover 8 is threaded with 5 of valve bodies, and an end of spring 7 withstands on the inboard of pressure regulating cover 8, by screwing or unscrew pressure regulating cover 8, can adjust the pressure of 7 pairs of spools 6 of spring, guarantee spool 6 actions accurately.For guaranteeing valve shaft 3 actions accurately and reliably, be provided with a valve shaft seat 13 at pressure regulating cover 8 bottom centre place, valve shaft 3 cooperates with the 13 formation activities of valve shaft seat.
The sealing configuration that valve shaft 3 and valve body are 5 can adopt packing box seal, also can adopt cup packing or other sealing configuration, and what this embodiment adopted is cup packing.
Marked the flow direction of liquid among Fig. 1 with the arrow form; just convenient structural feature to the utility model float valve describes; in fact liquid also can be the opposite flow direction, and the valve body structure characteristics are similar to Fig. 1, and such conversion also belongs to protection domain of the present utility model.
The structural feature of the utility model float valve makes it be applicable to that pressure is aqueous medium and other liquid medium of 0～10kg/cm2.
