Two tower organic exhaust gas hot oxidizing devices are the equipment for the treatment of waste gas.This equipment generally will use poppet valve.This poppet valve comprises valve shaft, and valve shaft is provided with valve plate, and valve plate both sides are respectively arranged with the valve seat be slidably matched with valve shaft.Above-mentioned poppet valve is mounted in casing and uses, described casing comprises two air vents be set up in parallel, be respectively the first air vent and the second air vent, casing top is provided with open top, the center-aisle be communicated with open top is provided with between first air vent and the second air vent, the two ends of center-aisle are separately installed with valve seat, and be provided with the valve plate be connected with valve shaft between two valve seats, described valve shaft and valve seat are slidably matched.Valve shaft is moved linearly by air cylinder driven.The movement of valve shaft can drive valve plate to move towards two valve seats, after valve plate to contact with one of them valve seat and seals, cannot be communicated with between the air vent that this valve seat is corresponding and the open top of casing, and air vent corresponding to another valve seat is just communicated with open top.Existing this poppet valve has the following disadvantages: because valve plate is solid, easily and between valve seat produces gap, make poorly sealed with valve seat after contacting.And valve seat is generally rigid collision when contacting with valve plate, the shock momentum of generation is comparatively large, easily causes damage to valve plate or valve seat.
Model utility content
The threeway that the technical problem that the utility model solves is to provide a kind of favorable sealing property promotes scavenging air valve.
The utility model solves the technological scheme that its technical problem adopts: threeway promotes scavenging air valve, comprise valve shaft, valve shaft is provided with valve plate, valve plate both sides are respectively arranged with the valve seat be slidably matched with valve shaft, described valve plate comprises elastic shell, and elastic shell inside is cavity.
Further: described valve seat outer circumference is to the sealing cord be provided with for contacting with valve plate.
Further: between described valve shaft and valve seat, be provided with self oiling bearing.
Further: described valve shaft and cylinders.
Threeway promotes scavenging air valve mounting structure, comprise casing, described casing comprises two air vents be set up in parallel, be respectively the first air vent and the second air vent, casing top is provided with open top, the center-aisle be communicated with open top is provided with between first air vent and the second air vent, the two ends of center-aisle are separately installed with valve seat, the valve plate be connected with valve shaft is provided with between two valve seats, described valve shaft and valve seat are slidably matched, described valve plate comprises elastic shell, and elastic shell inside is cavity.
Further: described valve seat outer circumference is to the sealing cord be provided with for contacting with valve plate.
Further: between described valve shaft and valve seat, be provided with self oiling bearing.
Further: described valve shaft and cylinders.
The beneficial effects of the utility model are: due to valve plate inner hollow and housing has certain elasticity, and therefore valve plate under external force certain distortion can occur when coordinating with valve seat, and this contributes to making valve seat and valve plate excellent sealing.Simultaneously owing to being provided with sealing cord, on the basis of improving sealing effect, reduce the shock momentum of valve plate and valve seat, be conducive to protection valve seat and valve plate.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As depicted in figs. 1 and 2, threeway of the present utility model promotes scavenging air valve, comprises valve shaft 11, valve shaft 11 is provided with valve plate 13, valve plate 13 both sides are respectively arranged with the valve seat 14 be slidably matched with valve shaft 11, and described valve plate 13 comprises elastic shell, and elastic shell inside is cavity 16.Above-mentioned elastic shell can be wrapped up by metallic material and forming.Such as wrapped up by steel plate and forming.The actuator of above-mentioned valve shaft 11 can comprise straight line driving mechanism, is preferably cylinder 12.
Because valve plate 13 is by realizing sealing with valve seat 14 collision rift, in order to reduce the vibrations degree because collision produces, to protect valve plate 13 and valve seat 14, on the basis of the above, described valve seat 14 outer circumference is to the sealing cord 15 be provided with for contacting with valve plate 13.Adopt said structure, sealing cord 15 direct collision of valve plate 13 and valve seat 14, sealing cord 15 can play the effect of damping, thus can reduce the vibratory output of valve plate 13 and valve seat 14, not only can play a protective role to valve plate 13 and valve seat 14, also can improve sealability.
In order to make the slip between valve shaft 11 and valve seat 14 smooth and easy, between described valve shaft 11 and valve seat 14, be provided with self oiling bearing.
As shown in Figure 6 and Figure 7, threeway of the present utility model promotes scavenging air valve mounting structure, comprise casing, described casing comprises two air vents be set up in parallel, be respectively the first air vent 21 and the second air vent 22, casing top is provided with open top 24, the center-aisle 23 be communicated with open top 24 is provided with between first air vent 21 and the second air vent 22, the two ends of center-aisle 23 are separately installed with valve seat 14, the valve plate 13 be connected with valve shaft 11 is provided with between two valve seats 14, described valve shaft 11 is slidably matched with valve seat 14, described valve plate 13 comprises elastic shell, elastic shell inside is cavity 16.During use, valve shaft 11 can be connected with cylinder 12, drives valve shaft 11 to move linearly by cylinder 12.Valve shaft 11 can drive the valve plate 13 on it to move.When the valve seat collision rift that valve plate 13 is corresponding with the first air vent 21, by the first air vent 21 shutoff, the first air vent 21 cannot be communicated with open top 24, now, the second air vent 22 is communicated with open top 24 by center-aisle 23.When the valve seat collision rift that valve plate 13 is corresponding with the second air vent 22, by the second air vent 22 shutoff, the second air vent 22 cannot be communicated with open top 24, now, the first air vent 21 is communicated with open top 24 by center-aisle 23.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
