Abstract
The controller is composed of valve body, micro switch, sealed film and valve cover. Inlet is setup at lower part of valve body, and sealed film is setup at upper part. There is a cavity between inlet and sealed film. Change of air pressure in cavity of the valve body drives elastic deformation of sealed film, which through bolt is connected to valve body. Micro switch is fixed on valve cap. Upwards deformation of sealed film triggers micro switch. Features are: simple structure, not touching water directly, less fault and high precision etc.
Description
Technical field vapour-pressure type water level controller of the present invention 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 objective of the invention is to avoid weak point of the prior art and provide a kind of variation that utilizes air pressure in the controller to promote sensitive switch, adopt contactlessly, controller is the direct contact water position not, and fault is few, the water level regulating and controlling is easy, the vapour-pressure type water level controller that accuracy is high.
The content of invention the objective of the invention is to reach by following measure, it is the variation by air pressure in the valve cavity, promote the sealed film strain, distortion contact and disengaging switch by sealed film, realization is to the control of water level height, prevent that controller from directly acting on the liquid water level, contactless control switch, it is by valve body, sensitive switch, sealed film, valve gap is formed, bottom at valve body is provided with import, and the top of valve body is provided with sealed film, between the sealed film on the import of the bottom of valve body and valve body top cavity is arranged, sealed film links together by bolt and valve body, top at valve body is provided with valve gap, and sensitive switch is fixed on the valve gap, by the upwards distortion triggering sensitive switch of sealed film, realization is to the control of water level height, prevent 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 present invention's 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 present invention is provided with import in the bottom of valve body, can control valve be set in import department.
The present invention 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 invention.
Accompanying drawing 2 is structural representations of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, operation principle of the present invention is the variation by air pressure in the valve cavity, promote the sealed film strain, distortion contact and disengaging switch by sealed film, realization is to the control of water level height, prevent that controller from directly acting on the liquid water level, contactless control switch, it 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, the top of valve body is provided with sealed film, between the sealed film on the import of the bottom of valve body and valve body top cavity is arranged, and air 3 is arranged in the cavity, top at valve body is provided with installation sheet, installation sheet and sealed film link together by bolt and valve body, on the top of valve body valve gap are set, and sensitive switch is fixed on the valve gap, valve gap links together by bolt and valve body, sealed film is provided with boss, is with a spring on the boss, and spring is arranged between sealed film and the installation sheet, sealed film is provided with spring leaf 14, boss correspondence on the sealed film the touch switch of sensitive switch, by the upwards distortion triggering sensitive switch of sealed film, realizes the control to the water level height, prevent that controller from directly acting on the liquid water level, when import 1 entered valve body lower portion water level 2 and raises, reduced in the space, top in the valve body, and air 3 pressure increase, make sealed film upwards be out of shape, 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 present invention 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.
