Abstract
The utility model relates to an automatic switch for water level and water pressure, which comprises a chassis and a shell cover, wherein, a water inlet port which is communicated with a water storage container through screws is arranged on the chassis. A microswitch is arranged above the shell cover. An elastic rubber sheet is arranged on an opening of the chassis. A push rod type touch button is arranged in the center of the elastic rubber sheet. With the function of water level and water pressure, the elastic rubber sheet deforms and drives the push rod type touch button to move upwards to touch a moving contact point of the microswitch. Then, electric current is switched on or cut off. The work pressure of the switch of the utility model can be flexibly adjusted. The utility model can be widely suitable for water tanks of various electric water heaters, water storage cans or other various pressure containers, with the advantages of high sensitivity, stable and reliable action of the switch, and wide purpose.
Description
The utility model relates to a kind of switch control technology, particularly a kind of water level height or hydraulic pressure size utilized carried out pressure controlled water level hydraulic pressure automatic switch, can be used for various electric heater water tanks and make automatic switch control, or be suitable in water storage condensers such as other various storage tanks, water tank, doing the automatic switch use of electrical equipment.
The present switch in electric heater or at the various storage tanks of needs with electric control, water tank, it is of all kinds to be used for controlling the switchtype that motor and water pump draws water in the tanks such as water storage tower, various in style, as being to control cut-offfing of heating wire switch by the knob design temperature in the domestic, electric water heater, the roof water tank water tower has plenty of with lever and floating controls cut-offfing of suction pump motor switch, but in tank, utilize water level hydraulic pressure to come the switch of control apparatus work still rare, particularly highly sensitive, this class water level hydraulic pressure automatic switch of the wide and conveniently adjusted setting hydraulic pressure that bears of modification scope is also found in market.
The purpose of this utility model is a kind of water level hydraulic pressure automatic switch of design, makes this switch can extensively be suitable at various electric heater water tanks or other storage tanks, conduct utilizes water level hydraulic pressure that electric switch is played automatic control action in the tank such as water tank, water tower, and have highly sensitive, conveniently adjusted, control safety, reliable and stable result of use.
The utility model is realized with following technical scheme: it mainly comprises chassis (or pan of a steelyard shape base) and cap composition, wherein the chassis is provided with the water inlet pipe mouth that can spin and be communicated with tank, the cap top is provided with microswitch (can adopt the microswitch of commercially available prod), on the Pan Kou on chassis, be provided with the elastic sheet rubber of formula sealing together, be installed with push-down in the center of elastic sheet rubber and bump button, under the effect of water level hydraulic pressure, elastic sheet rubber because of compressive deformation can drive push-down bump button move up touch microswitch movable contact to switch on or off electric current.
Water level hydraulic pressure automatic switch of the present utility model is owing to be provided with the elastic sheet rubber with the almost equal area of dish mouth cross section on the Pan Kou on chassis, compression area is big, and cap is furnished with set screw, make the operating pressure value of this automatic switch adjust flexibly and to set according to different tanks, so have highly sensitive, open or cut-off current reliable and stable, purposes is wide, can extensively be suitable in various electric heater water tanks, water tank or other various pressure vessels, using, and in check water level hydraulic pressure can be set arbitrarily.
Below in conjunction with accompanying drawing embodiment the utility model concrete structure is described in further detail.
Fig. 1 is a kind of overall structure schematic diagram of the present utility model.
Among the figure: 1～chassis (or pan of a steelyard shape base), 2～cap, 3～elastic sheet rubber (can be selected the temperature resistant rubber sheet for use according to need of work, oil resistant rubber sheet or General Purpose Rubber sheet), 4～sheet metal (forming) by stainless steel substrates, 5～microswitch (being the commercially available prod), 6～microswitch movable contact, 7～microswitch stationary contact, 8～push-down bumps button, 9～locking nut (the installation push-down bumps button and uses), 10～seal washer, 11～set screw, 12～holding screw (being used for fastening chassis and cap uses), 13～water inlet pipe (mouth of pipe is threaded).
With reference to accompanying drawing as can be known, the utility model also can have following technical characterictic when specific design is made:
But one, surface cushioning lastblock sheet metal 4 (as stainless steel substrates) above elastic sheet rubber 3.The purpose of pad dress sheet metal (stainless steel substrates) is to make the elastic sheet rubber compressive deformation even, and can improve installation strength and job stability that push-down bumps button 8.
Two, above cap, be connected with set screw 11, the flexible rubber web 3 operating pressure value of bearing can be adjusted according to actual needs flexibly.
