Abstract
An air pressure type water level controller of the utility model belongs to the field of control and actuating devices. The air pressure type water level controller is composed of a valve body, a microswitch, a seal film and a valve cap. The lower part of the valve body is provided with an entrance and the upper part of the valve body is provided with the seal film. The seal film is connected with the valve body through a bolt. The upper part of the valve body is provided with a valve cap. The microswitch is fixed on the valve cap. The microswitch is triggered through the upward deformation of the seal film. The utility model has simple structure. The controller can not directly contact the water level and the accident is less. The control and the regulating for the water level are easy and the accuracy is high. The utility model is an air pressure type water level controller which can effectively and sensitively obtain the control for the water level.
Description
Technical field the utility model vapour-pressure type water level controller belongs to control, adjusting device field, particularly relates to a kind of water level controller that utilizes baroswitch.
The existing water level controller of background technology is float-ball type normally, mainly be to utilize the leverage principle, utilize the lifting of ball float to come sensed water level, reach the purpose of control water level, controller directly acts on the liquid water level, is easy to generate the fault of blocking, and the water level regulating and controlling is not easy, poor accuracy, the insufficient sensitivity height.
The purpose of this utility model is to avoid weak point of the prior art and not direct contact water position of a kind of controller is provided, and fault is few, and the water level regulating and controlling is easy, the vapour-pressure type water level controller that accuracy is high.
The content the purpose of this utility model of utility model reaches by following measure, it is by valve body, sensitive switch, sealed film, valve gap is formed, bottom at valve body is provided with import, the top of valve body is provided with sealed film, and sealed film links together by bolt and valve body, on the top of valve body valve gap is set, sensitive switch is fixed on the valve gap, upwards distortion by sealed film triggers sensitive switch, realizes the control of water level height is prevented that controller from directly acting on the liquid water level, avoid blocking the fault of generation, reach the purpose of control water level because of lever.
The utility model sealed film is provided with boss, the boss correspondence the touch switch of sensitive switch, when the valve body lower portion water level is raised, reduce in space, top in the valve body, air pressure increases, and makes sealed film upwards be out of shape, and the boss that is provided with on the sealed film triggers sensitive switch, the water that cut-out enters from import is realized Water Level Control.
On the boss that is provided with on the sealed film, be with a spring, spring is arranged between sealed film and the installation sheet, when sealed film upwards is out of shape, overcome the elasticity of spring, sealed film could upwards promote boss and trigger sensitive switch, when decline of water table, at the effect lower seal film return of spring, the boss that promotes on the sealed film breaks away from sensitive switch.
The utility model is provided with import in the bottom of valve body, can control valve be set in import department.
The utility model is simple in structure, and controller is the direct contact water position not, and fault is few, and the water level regulating and controlling is easy, the accuracy height, and realization water level control that can be effective and sensitive is a kind of vapour-pressure type water level controller.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is by valve body 12, sensitive switch 7, sealed film 4, valve gap 8, import 1, installation sheet 5, spring 13 is formed, bottom at valve body is provided with import, and the top of valve body is provided with sealed film, on the top of valve body installation sheet is set, installation sheet and sealed film link together by bolt and valve body, top at valve body is provided with valve gap, and sensitive switch is fixed on the valve gap, and valve gap links together by bolt and valve body, sealed film is provided with boss, be with a spring on the boss, spring is arranged between sealed film and the installation sheet, and sealed film is provided with spring leaf 14, boss correspondence on the sealed film the touch switch of sensitive switch, upwards distortion by sealed film triggers sensitive switch, realizes the control of water level height is prevented that controller from directly acting on the liquid water level, avoid blocking the fault of generation, reach the purpose of control water level because of lever.When valve body lower portion water level 2 was raised, reduced in the space, top in the valve body, and air 3 pressure increase, and makes sealed film upwards be out of shape, and the boss that is provided with on the sealed film triggers sensitive switch, cuts off the water that enters from import, realizes Water Level Control.
Shown in the accompanying drawing 2, the utility model is provided with import 1 in the bottom of valve body 12, the top of valve body is provided with sealed film 4, on the top of valve body installation sheet 5 is set, installation sheet and sealed film link together by bolt and valve body, on the top of valve body valve gap 8 are set, sensitive switch 7 is fixed on the valve gap, sealed film is provided with boss, is with a spring 13 on the boss, and spring is arranged on the spring housing 17.
