Embodiment Construction

[0018] as attached figure 1 As shown, a pneumatic pulse valve that can be continuously and automatically opened and closed includes a pulse valve, a driving mechanism, a position sensor unit and a central control room. The pulse valve and the driving mechanism are fixedly connected by a support rod 4. The pulse valve includes a valve body 1. Valve seat 11, spool 10, bonnet 9 and valve stem 8. The valve body 1 is provided with an input channel 24 and an output channel 25. The valve stem 8 is connected to the bonnet 9 and can drive the bonnet 9 to move. The input channel 24 and the output channel 25 in the body 1 are opened and closed. The driving mechanism controls the opening and closing of the pulse valve by driving the movement of the valve stem 8 and the valve cover 9. There is a sealing device between the valve stem 8 and the pulse valve, and the position sensor unit is set on the support rod. The central control room and the position sensor unit Connected, the position s...

Abstract

The invention relates to a pneumatic pulse valve capable of continuously and automatically opening and closing, comprising a pulse valve and a driving mechanism, wherein the pulse valve and the driving mechanism are fixedly connected together through a supporting rod. The pulse valve comprises a valve seat, a valve cap arranged in a valve body and a valve rod capable of driving the valve cap to move. The driving mechanism is used for controlling the pulse valve to open or close through the motion of driving the valve rod and the valve cap, and a sealing device is arranged between the valve rod and the pulse valve. The pneumatic pulse valve capable of continuously and automatically opening and closing also comprises a position sensor unit and a central control room, wherein the position sensor unit is arranged on the supporting rod, and the central control room is connected with the position sensor unit. The position sensor unit can sense the action message of the valve rod and send the action message to the central control room, and the central control room is used for controlling the action of the driving mechanism. The pneumatic pulse valve capable of continuously and automatically opening and closing solves the technical problems that the traditional pulse valve can not automatically open or close and is inconvenient for detection, and the pneumatic pulse valve capable of continuously and automatically opening and closing can be continuously and automatically controlled to open or close.

Description

technical field [0001] The invention relates to a pulse valve capable of generating pulse air flow. Background technique [0002] The pulse valve is an important device of the ceramic high-temperature and high-pressure fly ash filter element online back-blowing cleaning system in the Shell pulverized coal gasification device. Solid impurities (filter cake). However, the existing pulse valve is driven by an electromagnetic drive mechanism to open and close the valve, which cannot detect the valve opening and closing time, and cannot realize continuous and automatic valve opening and closing state control. Contents of the invention [0003] In order to solve the technical problem that the existing pulse valve cannot realize the automatic opening and closing of the valve and the detection is inconvenient, the present invention provides a pneumatic pulse valve which can be continuously and automatically opened and closed. [0004] Technical solution of the present invention:...
