Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the floating ball type liquid level control device comprises a travel switch 1, wherein the travel switch 1 comprises a connecting rod 3, a normally closed contact 4, a normally open contact 5, a normally closed contact trigger rod 6, a normally open contact trigger rod 7, a contact protection limit rod and the like, the connecting rod 3 is of an L-shaped structure, one end of the connecting rod 3 penetrates through a shell of the travel switch 1 and is rotatably connected inside the travel switch 1, the other end of the connecting rod is positioned outside the travel switch 1, and a floating ball 2 is fixedly arranged at the tail end of the connecting rod; a normally closed contact trigger rod 6 and a normally open contact trigger rod 7 are symmetrically arranged on two sides of one end of the connecting rod 3, which is positioned in the travel switch 1, the normally closed contact trigger rod 6 and the normally open contact trigger rod 7 correspond to the normally closed contact 4 and the normally open contact 5, and the normally closed contact 4 and the normally open contact 5 are fixedly arranged in the travel switch 1; when the connecting rod 3 rotates anticlockwise, the normally closed contact trigger rod 6 and the normally open contact trigger rod 7 rotate along with the connecting rod 3, and when the normally open contact trigger rod 7 rotates to the position of the normally open contact 5, the normally open contact 5 acts, the contact is closed, and the circuit is connected; when the connecting rod 3 rotates clockwise, the normally closed contact trigger rod 6 and the normally open contact trigger rod 7 rotate along with the connecting rod 3, and when the normally closed contact trigger rod 6 rotates to the normally closed contact 4, the normally closed contact 4 acts, the contact is opened, and the circuit is opened. In order to protect the contacts from being damaged, a contact protection limiting rod is arranged outside the shell of the travel switch 1 to prevent the normally closed contact triggering rod 6 and the normally open contact triggering rod 7 from moving excessively, thereby protecting the contacts.
The floating ball 2 is a hollow sphere made of plastic or metal, the floating ball 2 floats on the liquid level in the liquid storage tank, the length of the connecting rod 3 can be selected according to the depth of the liquid storage tank and the limit of the liquid level, and the travel switch 1 is driven to act by utilizing the floating ball 2 to move up and down along with the liquid level, so that the start and stop of the conveying pump are controlled, and the liquid level is automatically controlled.
The working principle of the utility model is as follows: the travel switch 1 is fixedly arranged above the side of the highest liquid level of the liquid storage tank through a bolt, the floating ball 2 naturally sags and floats on the liquid level under the gravity, and when the liquid level descends, the floating ball 2 descends along with the liquid level. When the liquid level is lowered to the lowest limit, the travel switch 1 acts, the normally open contact 5 is closed, the delivery pump is started, the liquid storage tank inputs liquid, the liquid level gradually rises, and the floating ball 2 rises together with the liquid level. When the liquid level rises to the highest limit, the travel switch 1 acts, the normally closed contact 4 is opened, and the delivery pump stops. Thus, the automatic control of the liquid level is realized.
