At present, the unrestrained water tank of power plant's low level is owing to be subjected to constantly diffusion influence of water tank internal high temperature alkalescence steam (70-80 ℃), the water tank ambient humidity is big, the temperature height, big to liquid level gauge ball float and mechanical part corrosion, the liquid level gauge that makes present online use, comprise the frequent corrosion in contact and mechanical rotation position of electric contact type and float-ball type aut.eq., especially the float-ball type water level gauge mechanical rotation position corrosion that side direction is installed on the water tank is big, it is dumb to cause automatic level gauge to rotate, pointing accuracy reduces, can not use for a long time, often metal run out, jeopardize water pump operation.
Summary of the invention
The purpose of this invention is to provide a kind of automatic tank gauge that is used for power plant's low flush tank that increases the service life, reduces production costs.
The objective of the invention is to realize by following technical proposals:
The automatic tank gauge that is used for power plant's low flush tank of the present invention comprises that the top is provided with the non-closed hot water of vent port
Case, it is characterized in that being provided with the flange of band center pit at the top of described non-closed boiler, be provided with position-limiting drum with described center pit concentric at the lower surface of this flange, top at this position-limiting drum is provided with through hole, float displacement mechanism passes this through hole and inserts in the described position-limiting drum, upper surface at described flange is provided with position-limit mechanism, described position-limit mechanism is by the support that is respectively equipped with upper junction plate and lower connecting plate, what be connected with described upper junction plate goes up near switch, the sealing kettle that is connected with the lower surface of described lower connecting plate is located at this sealing following in kettle and forms near switch.Described going up near switch all is connected with electric control gear near switch with following.
Described float displacement mechanism inserts connecting rod in the described position-limiting drum by passing described center pit, by the coupling bolt ball float that is connected of an end of connecting rod therewith, by clamping screw therewith the limiting plate that is connected of the other end of connecting rod form.
Described going up near switch is the SC-3020AL type near switch with following near switch.
The material of described ball float is a stainless steel.
The characteristics that are used for the automatic tank gauge of power plant's low flush tank of the present invention are:
Be provided with position-limiting drum with the center pit concentric at the lower surface of flange, the top of this position-limiting drum is provided with through hole, the interior pressure of interior pressure of position-limiting drum and boiler is equated, liquid level in the while position-limiting drum equates that with the liquid level in the boiler displacement of ball float can truly reflect the height of liquid level like this.Float displacement mechanism is along with the height of liquid level moves up and down, when the liquid level in the boiler raises, the ball float of float displacement mechanism upwards moves in position-limiting drum, the drive limiting plate moves up and contacts near switch with last, connect electric control circuit, electric control gear control pump working is extracted the liquid in the boiler out; When the liquid level in the boiler reduces, the ball float of float displacement mechanism moves down in position-limiting drum, and the drive limiting plate moves down and contacts near switch with following, connects electric control circuit, electric control gear control water pump quits work, and has realized that the water level of boiler is controlled automatically.In order to prolong the serviceable life of liquid level gauge, following near switch be contained in very near apart from boiler sealed in the kettle, isolated wet steam prevents near switch failure, influences the operate as normal of liquid level gauge.
Advantage of the present invention is:
Realized automatic control of liquid, convenient for installation and maintenance, prolonged serviceable life of liquid level gauge, reduced production cost, increased the benefit of enterprise.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
As shown in Figure 1, the automatic tank gauge that is used for power plant's low flush tank of the present invention comprises that the top is provided with vent port
Power plant's low flush tank 15, it is characterized in that being provided with the flange 9 of band center pit at the top of described power plant low flush tank 15, be provided with position-limiting drum 14 with described center pit concentric at the lower surface of this flange 9, be provided with through hole 10 on the top of this position-limiting drum 14, pressure in the position-limiting drum 14 is equated with pressure in the power plant low flush tank 15, and the interior liquid level of position-limiting drum 14 and power plant low flush tank 15 interior liquid levels equate simultaneously.Float displacement mechanism passes this through hole and inserts in the described position-limiting drum 14, upper surface at described flange 9 is provided with position-limit mechanism, described position-limit mechanism is by the support 1 that is respectively equipped with upper junction plate 2 and lower connecting plate 7, what be connected with described upper junction plate 2 goes up near switch 3, with the sealing kettle 8 that the lower surface of described lower connecting plate 7 is connected, be located at following in this sealing kettle 8 and form near switch 6.Described going up near switch 3 all is connected with electric control gear near switch 6 with following.In order to prolong the serviceable life of liquid level gauge, following near switch 6 be contained in very near apart from boiler sealed in the kettle 8, isolated wet steam prevents near switch failure, influences the operate as normal of liquid level gauge.Described going up near switch 3 is the SC-3020AL type near switch with following near switch 6.The limiting plate 4 of ball float position-limit mechanism by with last near switch 3 with down near the contacting of switch 6, reach the purpose of automatic control liquid level.
