Detailed Description
In the embodiment shown in fig. 1, fig. 2, fig. 3, fig. 4, and fig. 5, the intelligent stop valve of the present invention comprises a valve body (1), a valve seat (2), a valve flap (3), a valve rod (4), a valve cover (5), a control box (6), a pressure transmitter (8), a safety valve (9), etc. The valve seat (2) of the intelligent stop valve is welded and connected with the valve body (1) by an upper welding seam and a lower welding seam. The valve seat (2) and the valve clack (3) can adopt a conical sealing surface or a plane sealing surface, the valve seat (2) is provided with an annular groove (13) at the outer circumference, the sealing surface of the valve seat (2) is provided with an annular convergence groove (11), a plurality of small holes (12) are uniformly arranged in the convergence groove (11), and a blind hole (14) is arranged in the same cross section. The convergence groove (11) is communicated with the annular groove (13) through a small hole (12) and a blind hole (14). A through hole (15) is formed in the valve seat (2) on the side face of the valve body (1), and the through hole (15) of the valve body (1) is communicated with the annular groove (13) of the valve seat (2).
One end of the pipe joint (10) is welded with the through hole (15) on the side surface of the valve body (1), the other end of the pipe joint is connected with a tee joint (18), and the tee joint (18) is connected with a pressure transmitter (8); the converging groove (11) of the valve seat (2) is communicated with the pressure transmitter (8) through a small hole (12), a blind hole (14), an annular groove (13), a through hole (15) of the valve body, a pipe joint (10) and a tee joint (18). The pressure transmitter (8) can rapidly detect the change of the medium pressure in the converging groove (11) of the valve seat (2). The safety valve (9) is installed on the upper portion of the tee joint (18), when the medium pressure exceeds the working pressure of the pressure transmitter (8), the safety valve (9) is opened rapidly to discharge the medium, and the pressure transmitter (8) is guaranteed to work under the safe working condition.
