Abstract
The utility model relates to a liquid level controller composed of a front seat cover (1), a back cover (4), an elastic bowl (5), an ejector rod (6), a support frame (7), a spring (8), a spring guard sheet (9), a lower liquid level control guard sheet (10), an upper liquid level control guard sheet (11), a toggle switch (12), etc. Since a switch structure of an elastic sheet ejector rod is adopted, the utility model has the characteristics of simple structure, easy use, easy adjustment and intuitional control. The utility model can be widely used for the control of liquid level under various situations, and is especially suitable for the automatic control of water level during pumping the water in a tall tower.
Description
The utility model belongs to liquid level control technology field, and specifically it is a kind of liquid level control detection device that is mainly used in aspects such as water tower draws water.
Control of existing liquid level and detection method are more, and commonly used have float-type, resistance-type, condenser type, pressure type or the like.Be to have introduced a kind of level gauging and control device in China's utility application prospectus of 91224630.8 as application number, it is made of source of the gas, measure-controlling unit, air shooter, pressure dispatch tube, pressure tube etc., it adopts pressure balance principle to measure and control liquid level, and this apparatus structure is complicated.Application number is to have introduced a kind of pressure type liquid level gauge in China's utility application prospectus of 90217156.9 for another example, and it is made up of shell, metallic membrane, push rod, two umbrella teeth, pointer, surface etc., and this device mainly is to be used for detecting liquid level.
The purpose of this utility model is to provide a kind of liquid level control detection device simple in structure, easy to use, to overcome the deficiencies in the prior art.
The purpose of this utility model can reach by following structures.The utility model has a preceding flap that is made of cover plate and pipe core, be connected with a bowl-shape bonnet that the centre is porose in preceding flap inboard, between preceding flap and bonnet, be connected with an elasticity bowl, be connected with a push rod at elasticity bowl center, push rod passes the hole in the middle of the bonnet, be connected with a support in the bonnet outside, on push rod, be with a spring, one end and the elasticity bowl of spring join, the other end and a rack-mount spring stop piece join, liquid level control catch on a following liquid level control catch and one is being installed on the other end of push rod, a toggle switch is installed on support, and it stirs bar down between liquid level control catch and the last liquid level control catch.When using, the utility model can connect with the bottom of Be Controlled liquid level container by its preceding flap pipe core like this, and output switching terminal connects with liquid level control circuit, and the pressure action that the liquid in containers position is produced is on the elasticity bowl.When liquid level descended, the pressure that acts on the elasticity bowl will reduce with the decline of liquid level, and the elasticity bowl will drive push rod and move in bonnet under the effect of elastic force own and spring force.When liquid level dropped to a certain position, the bar of stirring that will make down liquid level control catch drive toggle switch owing to moving of push rod made switch be in on-state, and at this moment hydraulic control system circuit will be started working and add liquid in container.When liquid level rose, the pressure that acts on the elasticity bowl will increase with the rising of liquid level, and the elasticity bowl will drive push rod and move outside bonnet under the effect of pressure.When liquid level rises to a certain position, owing to will making the bar of stirring of liquid control bit catch drive toggle switch, moving of push rod make switch be in off-state, and at this moment hydraulic control system circuit will be controlled it stop to add liquid in container.So just reached the purpose of control liquid level.
In order to adapt to the various situations in the actual use, upward liquid level control catch of the present utility model and following liquid level control catch can prolong its axis direction adjustment and move on push rod.Can determine liquid level on the Be Controlled liquid in the position on the push rod by adjust to move going up the liquid level catch like this, adjust and move down liquid level catch liquid level and under definite Be Controlled liquid, make the utility model more convenient in use in the position on the push rod.
Adjust in order to be convenient to when making and use, spring stop piece of the present utility model prolongs the axis direction of push rod and can adjust mobile on support.Adjust the elastic force of spring by adjusting its position like this, make the utility model be in best operational position.
The utility model has been owing to adopted flexure strip plunger switch structure, make the utlity model has simple in structure, effect is convenient, adjust easily, control characteristics intuitively, thereby reached the purpose of this utility model.
Accompanying drawing has provided an embodiment of the present utility model, further specifies concrete structure of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing 1 is a cross-sectional view of the present utility model.Among the figure, 1 is preceding flap, it is made of cover plate 2 and pipe core 3, be connected with a bowl-shape bonnet 4 that the centre is porose in preceding flap 1 inboard, between preceding flap 1 and bonnet 4, be connected with an elasticity bowl 5, be connected with a push rod 6 at elasticity bowl 5 centers, be connected with a support 7 in bonnet 4 outsides, on push rod 6, be with a spring 8, one end and the elasticity bowl 5 of spring 8 join, the spring stop piece 9 that the other end and is installed on the support 7 joins, liquid level control catch 11 on a following liquid level control catch 10 and one is being installed on the other end of push rod 6, a toggle switch 12 is installed on support 7, and it stirs bar 13 down between liquid level control catch 10 and the last liquid level control catch 11.
The utility model can be widely used in the control of various situation liquid levels, is specially adapted to the draw water automatic control of middle water level of high tower.
Claims (3)
