Abstract
The present invention relates to a pneumatic water level controller which belongs to the field of controlling and regulating devices. The lower part of a valve body is provided with an inlet, and the upper part of the valve body is provided with a sealing film; a hollow cavity is formed between the inlet at the lower part of the valve body and the sealing film at the upper part of the valve body, and air pressure change in the hollow cavity of the valve body drives the elastic deformation of the sealing film. The present invention is composed of the valve body, a microswitch, the sealing film and a valve cover, wherein the sealing film is connected with the valve body through screws; the microswitch is fixed to the valve cover and is triggered through the upward deformation of the sealing film. The present invention, the pneumatic water level controller, has the advantages of simple structure, indirect contact between the controller and water, low failure rate, easy water level control and regulation, high accuracy and effectively and sensitively realized water level control.
Description
Technical field vapour-pressure type water level controller of the present invention belongs to control, regulating 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 microswitch, 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 elastic deformation, 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 gauge tap, it is by valve body, microswitch, 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 microswitch is fixed on the valve gap, by the upwards distortion triggering microswitch 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 microswitch, 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 microswitch, 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 microswitch, 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 microswitch.
The present invention is provided with import in the bottom of valve body, can operation valve be set in inflow point.
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.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, principle of work of the present invention is the variation by air pressure in the valve cavity, promote the sealed film elastic deformation, 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 gauge tap, it is by valve body 12, microswitch 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 microswitch 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 microswitch, by the upwards distortion triggering microswitch 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 microswitch, 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, microswitch 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.
