Description

A rubber spring type pressure regulating module of a pressure regulator

technical field

The utility model relates to a rubber spring type pressure regulating module used for a voltage regulator, in particular to a rubber spring installed between the main spring seat and the body, through which the rubber spring can store and release elastic force, and then cooperate with the main spring The seat adjustment displacement allows the internal pressure to be balanced, so that the pressure adjustment operation can be carried out smoothly, and the purpose of adjusting the output pressure is achieved. The rubber spring can better control its own hardness, so that the application of the elastic range can be expanded.

Background technique

The internal pressure regulating structure of the pressure regulator 9 commonly used in the prior art is shown in Figs. Vertical displacement with the valve assembly 94, and then control the circulation or stop of the gas inside the pressure regulator 9; and when the piston 92 is displaced, it needs to increase the output force to solve the friction effect of itself, and the piston 92 has an incomplete seal The situation could be improved.

However, there are commercially available products that improve the above-mentioned structural shortcomings. Please refer to Figures 10 to 11 for their internal structures. Change it to a diaphragm 93 component, and the diaphragm 93 is mainly a composite material formed by bonding rubber-coated fiber cloth, and the diaphragm 93 has a certain elasticity and can cooperate with the internal valve assembly 94, so that the diaphragm cooperates with the gas to generate The deformation allows the gas to enter and exit, and this structure can mainly improve the friction of the piston, and can also output the force to achieve the purpose of pressure regulation; and the diaphragm 93 is made of rubber, and its material is affected by the fiber cloth, so there is no room for stretching. And limited by the characteristics of the composite material, the diaphragm 93 will eventually rupture due to the increase in the number of deformations and the force in the vertical and horizontal directions after long-term use; it can be seen from the above that the diaphragm 93 is still There is room for improvement.

The pressure regulating structure of the aforementioned piston 92 will be affected by the vertical force and frictional force, while the pressure regulating structure of the diaphragm 93 will be affected by the vertical and horizontal force and the composite material itself, resulting in a tight seal for the pressure regulating process. Problems caused by incomplete air leakage, slow pressure drop, abnormal pressure boost accuracy, diaphragm rupture, and insufficient air flow need to be improved urgently.

Detailed ways

Generally according to the utility model, after the best feasible embodiment is described in detail with the drawings, the understanding of the utility model is increased. The utility model is a rubber spring type pressure regulating module 2 of a voltage regulator, please refer to Fig. 1 As shown in Figure 3, a pressure regulator seat 11 is arranged on the upper part of the body 1, and a main spring 211 is arranged in the pressure regulator seat 11 for contacting the main spring seat 21. The body 1 has a pressure regulating air passage inside 12, and there is a valve part 13 in the pressure regulating air passage 12, a valve assembly 132 is provided under the valve part 13 for opening and closing the valve port 131, and a supporting spring 24 is provided under the valve assembly 132;

A pressure regulating module 2 is composed of a main spring seat 21 and a rubber spring 22, and the main spring seat 21 is provided with an anti-leakage cone surface 212, and the anti-leakage cone surface 212 is approximately 120 degrees, which can meet the actual production requirements. Change, its control range is approximately between 90 degrees to 150 degrees, not limited to the content of this embodiment; and the rubber spring 22 is an annular design, and is located between the main spring seat 21 and the valve part 13 of the body 1, and the The outer side of the anti-leakage cone surface 212 in the center of the main spring seat 21 is also provided with a ring-shaped limiting groove 213, and the outer side of the limiting groove 213 is also provided with a slot 214, which is mainly used to limit the rubber. Spring 22, in order to avoid the problem of lateral displacement caused by the extrusion of uneven applied force;

And the pressure regulating module 2 also has a positioning seat 23 located on the valve portion 13 of the body 1, the positioning seat 23 is an annular design, and the positioning seat 23 corresponds to the size of the limiting groove 213, when the main spring seat 211 is on the When moving up and down, the limiting groove 213 can be fitted into the positioning seat 23 correspondingly, so that the axes of the main spring seat 211 and the positioning seat 23 can keep corresponding to each other, and the lateral deviation of the valve assembly 132 can be avoided.

See again as shown in Figures 4 to 7, when the pressure regulator seat 11 rotates to the right, the rubber spring 22 will be squeezed and deformed by the main spring seat 21, and the valve assembly 132 will be pushed by it. Therefore, the valve port 131 of the valve will be opened, so that the gas enters the body 1 to form a pressure. Originally, the anti-leakage cone surface 212 and the spherical surface 133 are in a sealed state, but after the gas enters, the compressed elastic force is released through the support spring 24, and the valve will be released. The component 132 and the main spring seat 21 are pushed back to the original position, so that the internal pressure can be maintained in balance until the valve port 131 is closed; and when the pressure regulator seat 11 is turned to the left, the main spring 211 is relaxed, so that the rubber spring 22 can be Release the elastic force to push the main spring seat 21 to open the anti-leakage cone surface 212 to let the gas flow until the main spring seat 21 resets and closes the anti-leakage cone surface 212 .

Because the elastic modulus of the rubber spring 22 is an indefinite value, it cannot be calculated according to Hooke's law, but the elastic modulus can be determined by the hardness (Durometer Hardness) of the rubber spring 22, and the greater the hardness, the stronger it will be after deformation , can withstand greater pressure (relevant calculations are well known in the art, and will not be repeated here), and the rubber spring 22 mentioned in the content of the utility model has a basic hardness of 40 degrees, which can be physically or chemically adjusted according to production requirements. The hardness and volume can be adjusted, and the adjustment range can be between 40 degrees and 90 degrees. Compared with the piston and diaphragm composite materials used in the prior art, the structure of the rubber spring 22 is relatively simple, and it can be used within the elastic range. There is no problem of elastic fatigue, so the service life is longer.

In summary, it can be seen that the utility model mainly improves the responsiveness of the return stroke of the main spring seat 21 through the rubber spring 22 in the pressure regulating module 2; furthermore, the hardness of the rubber spring 22 can be adjusted to make the rubber The elastic range of the spring 22 is expanded, and can be applied to voltage regulators or more products.
