The specific content indicates that this product relates to the field of valve industry, especially refers to a large diameter gas medium electric valve. There are many kinds of valves in the characteristics of creative environmental technology, such as gate valve, disc valve, gate valve and so on. This kind of valve, like gate valve, disc valve is mainly for liquid gate control, which is very heavy, expensive and lack of sealing. Gate valve is used in the opening and closing of steam fluid, because of the reason of structure, it can not complete the sealing effect, and small diameter valves are very few, the cost is high. This product clearly proposes a large diameter gas medium electric valve, used for steam body safety channel seal, compared with gate valve, disc valve, globe valve, not only more lightweight, and greatly improve the sealing characteristics of the valve, can make a variety of large pipe through the valve, suitable for a variety of ventilation pipe road, Effectively solve the bottleneck problem that it is difficult to seal gate valve when it is used in vapor body liquid, especially small diameter valve when it is used in vapor body liquid. The technical solutions of this product are as follows: Large diameter gas medium electric valve comprises an outer shell, the outer shell is respectively provided with a base plate and an auxiliary base plate, the base plate is arranged above the assistance base plate, the base plate is provided with a ventilation hole, the base plate and the assistance base plate is provided with a plurality of guide column, the guide column is provided with a rolling plate and a pressure plate for manipulating the opening and closing of the ventilation hole gate, A vibration isolator is arranged between the pressure plate and the gate plate, and a linear driving device is connected with the pressure plate to push the right and left straight motion. The upper limit phase sensor is provided on the pressure plate to test the middle position relationship between the pressure plate and the gate plate, and the low limit phase sensor is provided on the assist substrate to test the middle position relationship between the pressure plate and the assist substrate. An elastic sealing ring is arranged between the vent holes of the ram plate and the base plate. The rear surface of the substrate is provided with a sealed oil cup which is provided with a sealed vegetable oil. The linear driving device comprises a nut fixed and fixed in the press plate, and a ball screw is arranged in the nut, and the ball screw is connected with a reducer, and the reducer is fixed and fixed and fixed on the assistance ram. A connecting pin is arranged between the pressure plate and the gate plate. The ram is provided with a sealing riser for sealing the gap between the ball screw and the ram. The total number of the guide column is four, and the vibration isolator contains four torsion springs corresponding to the guide column one by one, and each of the torsion springs is set on the corresponding guide column. The ram plate is provided with a machine travel switch for limiting the protection of the reducer after the destruction of the phase sensor, and the second mechanical device travel switch for protecting the reducer after the destruction of the low limit phase sensor is provided on the assist substrate. Using the above technical specifications, the effective practical effect of this product is: Because the outer shell of the large-diameter gas medium electric valve is respectively provided with a base plate and an auxiliary base plate, the base plate is provided with a ventilation hole, the guide column is provided with a rolling plate and a ram, the middle of the pressure plate and the ram is provided with a vibration isolator, the pressure plate is connected with a linear driving equipment to promote its left and right linear motion, the pressure plate is provided with a limiting phase sensor, assist the base plate is provided with a low limit phase sensor. When working, the reducer pushes the ball screw to rotate. According to the nuts in the press plate, the rotary movement of the ball screw is transformed into the up and down movement of the press plate. The press plate promotes the ram to move up and down according to the torsion spring, so as to realize the opening and closing of the valve. When you want to close the valve, the reducer shaft drives the ball screw to rotate, there is a matching nut with the ball screw on the pressure plate, the ball screw causes the pressure plate to move upward, and the four guiding columns ensure the balance of the pressure plate when the ram moves to the top, the pressure plate presses the torsion spring, torsion spring presses the ram, the ram and the base plate of the air hole in the middle of the elastic sealing ring, Seal ring perimeter is coated with sealing plant grease, ram pressure seal ring, the gas supply is turned off. The sensor of the limiting position detects the position relationship between the pressure plate and the ram, and sufficient working pressure accumulated by the torsion spring can tamp and seal the ventilation hole. The sensor obtains data signal and controls the reducer to stop rotating. In this way, after the ram seals and closes the ventilation hole, the pressure plate cannot continue to exercise, which can not only ensure the compaction of the ram, but also avoid the destruction of mechanical equipment. When the valve is to be opened, the motor shaft rotates in the opposite direction, as well as the low limit phase sensor when the pressure plate arrives at the given position, the data signal is obtained, the motor stops rotating and the valve is opened. The structure type of this product uses torsion spring to have the following expression effect, to ensure that the ram must be pressurized, and the four guide columns cooperate with each other, so that the ram can bear symmetrical force; Second, can give the motor operation empty enough to reflect the indoor space, motor more or less rotation can ensure the actual effect of sealing, and effectively control the quality and service life of the valve; Third, according to the clamping ram connecting pin, a original working pressure is given to the torsion spring, so that the clamping ram and the clamping ram maintain a cuboid position relationship, so that when the ball screw rotates, the clamping ram can roll freely on the guide column, and it is not easy to get stuck. The inventor designs the plate sealing structure of this kind of electric regulating valve according to the innovative thinking ability. The valve is sealed by the intermediate pressure between the ram and the elastic gasket, and the gasket has a certain elasticity. Only the ram can reach a certain working pressure, which can achieve good sealing and greatly improve the sealing characteristics of the valve. Because the back surface of the substrate is provided with a sealing oil cup, further fill and enhance the actual sealing effect of the elastic gasket. Because the ram is provided with a sealing riser, it can effectively seal the gap between the ball screw and the ram. Because the ram is provided with a mechanical device travel switch, the second mechanical device travel switch is provided on the base plate. If the limiting phase sensor is damaged, when the pressure plate is too close to the ram, the normal closing point of the mechanical device travel switch will be broken, and the power supply of the reducer will stop; If the low limit phase sensor is destroyed, the pressure plate is too close to the assist substrate, the second mechanical device stroke switch normally closed point breaks off, the reducer stops power supply, so that the valve can be better maintained without damage. In general, this product is used for steam safety channel seal, compared with gate valve, disc valve, globe valve, not only more lightweight, and greatly improve the sealing characteristics of the valve, can make a variety of large pipe through the valve, suitable for a variety of ventilation pipe road, effectively solve the gate valve used in steam liquid, especially small diameter valve used in steam liquid to achieve sealing bottleneck problem. It has far-reaching significance in the field of valves.
