[0005] The first object of the present invention is to provide a method for adjusting the spring range of a pneumatic diaphragm actuator, so as to solve the problem that the installation position of the spring in the diaphragm chamber of the existing pneumatic diaphragm actuator in the prior art is fixed, and after installation, the There is no adjustment space for the amount of compression. When adjusting different spring ranges, the only technical problem is to replace the spring.
[0006] The second object of the present invention is to provide a method for adjusting the spring range of a pneumatic diaphragm actuator in the application of the pneumatic diaphragm actuator, so as to solve the problem of the installation position of the spring in the diaphragm chamber of the existing pneumatic diaphragm actuator in the prior art. Fixed, after installation, there is no adjustment space for the compression of the spring. When adjusting different spring ranges, only the technical problem of replacing the spring

Embodiment 1
[0035] Adjust the spring range from 0.02 to 0.10MPa to 0.04 to 0.12MPa.
[0036] see figure 2 , is the assembly drawing when the spring range is 0.02-0.10MPa. At this time, several self-made washers 9 are arranged under the tray 3, the total thickness of the washers 9 is 10mm, the number of springs 4 is 3, and the 3 springs 4 are evenly arranged On the spring seat and in full contact with the tray 3, the height of the spring 4 after compression is about 112 mm. When the spring range is to be adjusted to 0.04-0.12Mpa, keep the number of springs 4 unchanged, remove several washers 9, make the total thickness of washers 9 be 6mm, and the height of spring 4 after compression is about 108mm. At this time, The spring range of the pneumatic film actuator is 0.04 ~ 0.12Mpa, such as image 3 .
Embodiment 2
[0038] Adjust the spring range from 0.02 to 0.10MPa to 0.04 to 0.20MPa.
[0039] see figure 2 , is the assembly drawing when the spring range is 0.02-0.10MPa. At this time, several self-made washers 9 are arranged under the tray 3, the total thickness of the washers 9 is 10mm, the number of springs 4 is 3, and the 3 springs 4 are evenly arranged On the spring seat and in full contact with the tray 3, the height of the spring 4 after compression is about 112mm. When adjusting the range of the spring to 0.04-0.20MPa, keep the total thickness of the washer 9 unchanged, and add 3 springs, so that the spring 4 is evenly arranged on the spring seat and fully in contact with the tray 3. At this time, the pneumatic film performs The spring range of the mechanism is 0.04~0.20MPa, such as Figure 4 .
Embodiment 3
[0041] Adjust the spring range from 0.02 to 0.10MPa to 0.08 to 0.24MPa.
[0042] see figure 2 , is the assembly drawing when the spring range is 0.02-0.10MPa. At this time, several self-made washers 9 are arranged under the tray 3, the total thickness of the washers 9 is 10mm, the number of springs 4 is 3, and the 3 springs 4 are evenly arranged On the spring seat and in full contact with the tray 3, the height of the spring 4 after compression is about 112mm. When adjusting the spring range to 0.08-0.24MPa, remove several washers 9 so that the total thickness of the washers 9 is 6mm. 3 Full contact, the height of the spring after compression is about 108mm, at this time, the spring range of the pneumatic film actuator is 0.08 ~ 0.24MPa, such as Figure 5 .

Abstract
The invention provides a method for regulating spring ranges of a pneumatic diaphragm actuating mechanism, which is applied to the pneumatic diaphragm actuating mechanism. The method comprises the steps of (1) arranging a plurality of springs on a spring seat of a second diaphragm cover member; (2) arranging a limit part between a first diaphragm cover member and the second diaphragm cover member, sleeving a plurality of gaskets, a pallet and a diaphragm piece at one end of the limit part, enabling the limit part, the gaskets, the pallet and the diaphragm piece to sequentially connected for fixing through connecting parts, and enabling the springs to abut against the pullets; (3) enabling the first diaphragm cover member and the second diaphragm cover member to be connected for fixing through connecting parts; and (4) regulating the number of the springs and / or the number of the gaskets when the spring ranges are required to be regulated. Compared with the prior art, the method can regulate different spring ranges in the same stroke by only regulating the number of the springs and / or the number of the gaskets, thereby reducing types of stocked springs, saving cost, greatly reducing storage and facilitating storage management and pre-assembling of diaphragm heads.
Description
technical field [0001] The invention relates to the technical field of an actuator for automatic adjustment of a regulating valve, in particular to a method for adjusting the spring range of a pneumatic film actuator and its application. Background technique [0002] Pneumatic film regulating valve is a kind of control device in the combination instrument of pneumatic unit. It is one of the important devices in the automatic adjustment system of the production process. It can be widely used in automatic adjustment and remote control of chemical industry, petroleum, metallurgy, electric power, light textile industry. At present, the commonly used pneumatic film regulating valve is mainly composed of a valve mechanism and an actuator, and the two are connected by a push rod connected in the middle. The existing actuator consists of an upper membrane cover, a lower membrane cover, a diaphragm, a spring, and a bracket connected to the lower part of the lower membrane cover. On ...
