Technical Field

The utility model belongs to the technical field of chemical pipeline transportation technique and specifically relates to a novel double acting remote control pneumatic valve.

Background

In petrochemical industry, many large-scale pipelines adopt straight-stroke pneumatic flange gate valves as valves, and the benefit is that the flashboard is straight from top to bottom, and the structure is succinct, and the reliability is very high, and the flashboard of its heavy-calibre is very thick and solid, and the flashboard still can use after pipeline damage usually, but its pneumatic part then is not, uses usually about 3 years and just needs the whole change (although many producers declare its design life is ten years, according to the experience of petrochemical industry, most valves use about three years and will go wrong). But the existing products are expensive. Taking the LDZP700 straight-stroke pneumatic flange gate valve of the Leiden brand as an example, the price of the LDZP700 straight-stroke pneumatic flange gate valve is up to 46000 Yuan RMB one. Small enterprises are not capable of bearing load at all.

In view of the characteristics that the flashboard of gate valve is difficult to damage, there are some small enterprises to begin to become old and useless gate valve through reforming transform into simple and easy manual valve, electric valve or pneumatic valve, but it is all too inconvenient to use.

The technical scheme of the utility model is that:

the utility model provides a novel double acting remote control pneumatic valve, it includes the main part (that is the pneumatic flanged gate valve of former straight stroke demolishs the remaining part behind the pneumatic part) and the activity sets up the flashboard in the main part, its characterized in that: the flange head at main part top has a flange pipe fitting through screwed connection, the top seal of flange pipe fitting, be equipped with a piston in the flange pipe fitting, the flashboard in the main part is connected through a connecting rod to the piston, flange pipe fitting upper left side, upper right side, left downside and right downside communicate respectively has first intake pipe, first outlet duct, second intake pipe and second outlet duct, the solenoid valve is all installed to the mouth of pipe department of first intake pipe, first outlet duct, second intake pipe and second outlet duct.

In some embodiments, the electromagnetic valves corresponding to the first air inlet pipe, the first air outlet pipe, the second air inlet pipe and the second air outlet pipe are all connected with the same electromagnetic valve controller through conducting wires, so that the operation of workers is facilitated.

In some embodiments, the electromagnetic valves corresponding to the first air inlet pipe, the first air outlet pipe, the second air inlet pipe and the second air outlet pipe are all wirelessly connected with the same electromagnetic valve controller, so that remote control is facilitated.

In some embodiments, the connecting rod extends through the piston and upwards to penetrate through the top of the flange pipe fitting, a hand wheel is screwed on the top of the connecting rod, the four electromagnetic valves can be detached when power is cut off, and then the gate plate is lifted or pressed down by holding the hand wheel by hand.

In some embodiments, the connecting rod is detachably connected to the piston, and the piston needs to be replaced periodically because the piston edge is necessarily the first to be damaged after long-term use.

In some embodiments, a bushing is arranged between the inner wall of the flange head of the main body and the connecting rod, and the bushing is welded with the inner wall of the flange head to reinforce the radial support of the connecting rod. Permanent fixed has been done here, because the utility model discloses a meaning just lies in reforming transform old and useless valve main part, if appear damaging the back when the flashboard, other parts have just also lost meaning, so here has done permanent fixed, and the flashboard can not break away from the main part.

In some embodiments, a sealing ring is arranged between the top of the flange pipe fitting and the connecting rod, so that air leakage is reduced.

The utility model has the advantages that: the waste valve main body is used for transformation, and the pneumatic mechanism with a simple structure is replaced again, so that the up-and-down movement of the flashboard is realized, the structure is simple, the price of raw materials is low, the maintenance cost is low, and even simple remote control can be realized.
