The purpose of the utility model realizes through following technical proposals:
The automatic tank gauge that is used for power plant's low flush tank of the utility model; Comprise that the top is provided with the non-closed boiler of vent port; It is characterized in that being provided with the flange of band center pit, be provided with the position-limiting drum with said center pit concentric, be provided with through hole on the top of this position-limiting drum at the lower surface of this flange at the top of described non-closed boiler; Float displacement mechanism passes this through hole and inserts in the described position-limiting drum; Upper surface at said flange is provided with position-limit mechanism, and described position-limit mechanism is by the support that is respectively equipped with upper junction plate and lower connecting plate, and what be connected with said upper junction plate goes up near switch; The sealing kettle that is connected with the lower surface of said 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 the connecting rod in the said position-limiting drum by passing said center pit, through the coupling bolt ball float that is connected of an end of connecting rod therewith, through 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 said ball float is a stainless steel.
The characteristics of the automatic tank gauge that is used for power plant's low flush tank of the utility model are:
Be provided with the 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; Pressure in the position-limiting drum is equated with the interior pressure of boiler; Liquid level in the position-limiting drum equates that with the interior liquid level of boiler the displacement of ball float can truly reflect the height of liquid level so simultaneously.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, and the drive limiting plate moves up and contacts near switch with last, connects 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.
The utility model has the advantages that:
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 the structural representation of the utility model.
Embodiment
Embodiment below in conjunction with description of drawings the utility model.
As shown in Figure 1, the automatic tank gauge that is used for power plant's low flush tank of the utility model 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 the position-limiting drum 14 with said 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, the pressure in the position-limiting drum 14 is equated with pressure in the power plant low flush tank 15, the interior liquid level of position-limiting drum 14 equates with power plant low flush tank 15 interior liquid levels simultaneously.Float displacement mechanism passes this through hole and inserts in the described position-limiting drum 14; Upper surface at said 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 said upper junction plate 2 goes up near switch 3, with the sealing kettle 8 that the lower surface of said lower connecting plate 7 is connected, is located at following to 6 compositions of switch in this sealing kettle 8.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 through with last near switch 3 with down near the contacting of switch 6, reach the purpose of automatic control liquid level.
