Abstract
The utility model relates to a full-automatic differential pressure type gate valve, which comprises a valve body, a valve seat, a flashboard, a valve rod, a valve cover, a bracket, an electric device, a sealing part and a mounting part, wherein the lower end of the valve rod is fixedly connected with the flashboard, and the upper end of the valve rod is connected with the electric device through a valve rod nut. The gate valve is mainly characterized in that: a first pressure sensor is arranged in an inlet channel of the valve body, and a second pressure sensor is arranged in an outlet channel of the valve body; and a differential pressure signal is generated by a controller according to pressure signals of the first and second pressure sensors, and is connected to a control circuit of the electric device. An electric signal which is directly proportional to differential pressure is generated by the controller according to the pressure signals of the first and second pressure sensors to control the electric device to adjust the opening of the flashboard. The gate valve has a flow regulation function.
Description
Technical field
The utility model relates to valve field, particularly about a kind of gate valve.
Background technique
The structure of existing gate valve generally is made up of valve body, valve seat, flashboard, valve rod, valve gap, support, driving mechanism, Sealing and assembling set; The valve rod lower end is fixedly connected with flashboard; The upper end is connected with driving mechanism through Stem Mut; Move up and down by driving mechanism transmission valve rod, drive flashboard and open or close.Its shortcoming is accurate rate of discharge.
Summary of the invention
The purpose of the utility model is the shortcoming that exists to existing technology, and a kind of full-automatic differential gate valve that can accurately regulate rate of discharge is provided.
The technological scheme of the utility model comprises valve body, valve seat, flashboard, valve rod, valve gap, support, Electric actuator, Sealing and assembling set; The valve rod lower end is fixedly connected with flashboard; The upper end is connected with Electric actuator through Stem Mut; Mainly be in the valve body inlet passage, to be provided with first pressure transducer; Be provided with second pressure transducer in the outlet passage, the pressure signal of said first pressure transducer and second pressure transducer forms pressure difference signal in controller, and this pressure difference signal is connected in the control circuit of Electric actuator.
The utility model has the advantages that and adopt sensor valve body inlet/outlet pressure, produce the aperture that pressure difference signal control Electric actuator is regulated flashboard, have the function of Flow-rate adjustment through controller.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Full-automatic differential gate valve as shown in Figure 1; Comprise valve body 1, valve seat, flashboard 2, valve rod 5, valve gap 6, support 8, Electric actuator 10, Sealing and assembling set; Valve rod 5 lower ends are fixedly connected with flashboard 2, and the upper end is connected with Electric actuator 10 through Stem Mut 9, in valve body 1 inlet passage, is provided with first pressure transducer 4; Be provided with second pressure transducer 3 in the outlet passage; The pressure signal of said first pressure transducer 4 and second pressure transducer 3 forms pressure difference signal in controller 7, this pressure difference signal is connected in the control circuit of Electric actuator 10, the working state of control Electric actuator 10; And pass through the aperture that valve rod 5 is controlled flashboards 2, reach the adjusting of rate of discharge.The function of controller 7 is the pressure signals that receive first pressure transducer 4 and second pressure transducer 3, produces the electrical signal that is directly proportional with both pressure differences after treatment, the working state of this electrical signal control Electric actuator 10.
