The groove 6 runs through the end face of left and right two of the riser 1 (left and right is for front view)；
In the present embodiment, only in the case of a valve body, if the solid section of flashboard 2 is aligned by riser 1 and wind
During the air channel that interface tube 4 is formed, air channel is closed, as shown in Figure 5；If the second through hole 21 of flashboard 2 is aligned into air channel, air channel is beaten
Open, as shown in Figure 7.
Embodiment 2
On the basis of embodiment 1, the valve body quantity in the electric push-and-pull gate valve can be 2, using institute in embodiment 1
The flashboard 2 stated can make the first through hole 11 in two valve bodies while one opening of opening or a closing, as shown in Fig. 8~9.Should
In the case of, two valve bodies can one be that air intake one is air-out, then two valve bodies of air intake and air-out can use a flashboard 2 simultaneously
Control；Certainly, two valve bodies be may be alternatively provided as it is air intake or is air-out according to being actually needed.
If the solid section length increase in the left side of flashboard 2 is set also to realize two for that by two valve bodies while can shelter from
Individual valve body is turned off, as shown in Figure 10~11.
If setting two the second through holes 21 coordinated with two valve bodies on the right side of flashboard 2 simultaneously, left side is set can be simultaneously
Stop the solid section of two first through hole 11, as shown in Figure 12~14, then control is more convenient, and will not be from two risers 1
Between gap in leak out, therefore, if conditions permit, preferential this method control.
Embodiment 3
On the basis of embodiment 1 or 2, the valve body quantity in the electric push-and-pull gate valve can be more than 2, the flashboard
2 can simultaneously control all valve bodies by extending length, and principle can be found in embodiment 1 or 2.
Specifically, one end of the flashboard 2 is the solid section that can block the first through hole 11 on all valve bodies, described
The other end of flashboard 2 is provided with multiple second through holes 21, and second through hole 21 can be with the quantity one of the first through hole 11
Cause, and can correspond and coordinate with first through hole；The flashboard 2 be provided with second through hole 21 one end with it is described electronic
Push rod 7 connects.It then can be achieved to control while multiple valve bodies, control mode leads to the control mode of accompanying drawing 12~14 in embodiment 2.
Embodiment 4
When it is implemented, it is stroke 180mm thrust 750N, operating voltage DC24V that electric pushrod 7 is available.It is electronic to push away
Bar 7 can also order goods with producer according to demand in electrical equipment market purchasing.
Base can be manufactured with carbon steel or stainless steel, and base and column 9 are welding processing, are then made at zinc-plated or other anti-corrosions
Reason.
Body portion：Pad 3 is manufactured by the thick steel discs of 1.5mm, and it controls two pieces of risers 1 to ensure midfeather after combining
It is 1.5mm, ensures the sealing that sealing strip 61 and ring washer have suitable decrement to keep gate valve, while ensures that 1.2mm is thick again
Flashboard 2 have suitable gap in 1.5mm space, push-and-pull slides freely.First through hole 11, the second through hole 21 and airduct connect
The diameter of mouth 4 can be 150mm or so, and the external diameter (i.e. external diameter major part) that duct collar 4 is connected side with riser 1 is
160mm or so, the height of duct collar 4 can be 30mm, wherein, the height of external diameter wider portion is 10mm or so, and external diameter is smaller
Free end 20mm or so.304 stainless steels can be selected in the screw being related to；Aluminium alloy can be selected through porcelain sun in riser 1
Polarization process is that is, light and corrosion-resistant.Fluorine glue material matter can be selected in sealing strip 61 and ring washer, and temperature in use can reach 140
DEG C, simple in construction, electric butterfly valve (cheap 1/3) of the manufacturing cost less than market with flow.
Flashboard 2：From 304 bright plate manufactures, surface smoothness is good, and friction is small, corrosion-resistant, and rigidity and intensity are high.
Operation principle：Electric pushrod 7 is become in the presence of DC24V voltage, electronic rotation by worm gear auxiliary driving
Into the linear reciprocating motion of push rod, flashboard 2 is driven, realizes and pulls out and promote, each air channel (is had duct collar 4 and first
The air channel that through hole 11 is formed) action connected with closing is produced, so as to realize the control to air channel.Have inside electric pushrod 7
Stopping means, position is arrived and has been automatically stopped and commutates.
Electric push-and-pull gate valve, operate steadily, no noise, windage are small, distinguished and admirable flux is big and will not produce vortex and rapid
Flow phenomenon, it is easy to accomplish Automated condtrol.
Plug-type gate valve in the present embodiment, it is adapted to the occasion of low pressure (1200Pa) big flow.Can be same if lengthening riser 1
When 2~5 air channels even more air channels.The electric pushrod 7 of different strokes need to be allocated.Same open can be satisfied with during multi-way contral
With the control requirement closed.This is that electric butterfly valve institute is irrealizable.It is equipped with the time relay or the control of other circuits can be used for
Automatic production line is supporting.
For the electric push-and-pull gate valve in the present invention, every will fill 3 sets of present invention in the curing of the applicant's production
Described electric push-and-pull gate valve.From 2014 till now, 60 sets of electric push-and-pull gate valves of 20 equipment are smoothly run always,
It is not out of order.
In the present invention, when the quantity more than one of valve body, solid section and the portion provided with the second through hole 21 on flashboard 2
Dividing flexibly to be set, and the flexible control of different first through hole 11 is realized, but as long as principle as the present invention, belongs to this hair
Bright protection domain.
In addition, the flashboard 2 in the application can be not provided with the second through hole, then flashboard 2 is stretched into the gap between riser 1 just
Air channel can be closed, all pulling out can realize and all connect.But this method there may be situations such as leaking out, therefore the applicant passes through
Use for many years gradually optimizes, and has obtained the flashboard flexibly containing the second through hole.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for those skilled in the art
For, the present invention can have various changes and change.All any modifications made within spirit and principles of the present invention, it is equal
Replace, improve etc., it should be included in the scope of the protection.
