Abstract
A regulating valve oil motivator resetting mechanism comprises an elastic body arranged between a piston and a base of an oil motivator and comprising a first spring and a second spring, wherein the second spring is sheathed in the first spring, and the first and second springs are coaxial. The resetting mechanism adopts the double-layer combined springs which include the first and second springs coaxially sheathed, and are installed between the piston and the base of the oil motivator by a support mechanism, thereby forming the simple, effective and economic regulating valve oil motivator resetting mechanism under the conditions of not exceeding the restrictions on designed installation sizes and meeting burden requirements, so that the closing time of an oil motivator valve can satisfy standards.
Description
Technical field
The utility model relates to a kind of resetting-mechanism, relates in particular to a kind of resetting-mechanism that is applied on the modulating valve oil engine.
Background technique
The modulating valve oil engine is the actuator of modulating valve, and it will be the stroke output of enough acting abilities to be arranged to handle modulating valve by the secondary oil signal conversion of amplifier or electro-control converter input.The unlatching of oil engine is driven by high pressure oil, is to lean on resetting-mechanism and close.The single spring of the general employing of the design of domestic modulating valve oil engine resetting-mechanism, it is less to load, and causes the minimum shut-in time bigger.If because of the demand of reality reduces the minimum shut-in time, can only increase the diameter of Returnning spring, certainly will cause the increase of oil engine external diameter, and then cause the variation of associated components sizes such as piston, thereby cause cost further to increase.
The model utility content
The utility model technical problem to be solved provides a kind of modulating valve oil engine resetting-mechanism; It can realize under the condition that does not increase the oil engine external diameter that elastic force increases; Make the oil engine valve closing time meet standard, thereby eliminate defective in the above-mentioned background technology.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
Modulating valve oil engine resetting-mechanism; Comprise the elastomer that is installed between oil engine piston and the oil engine base; Said elastomer comprises first spring and second spring, and said second spring housing is loaded in said first spring, and said first spring and second spring are coaxial.
As a kind of improvement, the rotation direction of said first spring and second spring is opposite, and this structure can prevent that two springs from interfering with each other.
As a kind of improvement, said oil engine piston is provided with the supporting mechanism that is used to install said first spring and second spring.
As a kind of further improvement, said supporting mechanism comprises and is used to the position block that prevents that said second spring from radially sliding.
In addition,, between said first spring and second spring suitable radial clearance should be arranged as the design of routine, and first spring and second spring need satisfy free height and curl up than should equate substantially, intensity equates basically and press and equal highly basically.
The utility model has following beneficial effect owing to adopted above structure:
The utility model adopts double-deck cluster spring; First spring and second spring that comprise coaxial package; Utilize supporting mechanism to be installed between oil engine piston and the oil engine base, neither exceeding the design and installation size restrictions, satisfy again under the situation of burden requirement; Form simple and direct, effective, economic modulating valve oil engine resetting-mechanism, make the oil engine valve closing time meet standard.
Description of drawings
Accompanying drawing is the utility model structural representation;
Among the figure: 1. oil engine piston, 2. oil engine base, 3. first spring, 4. second spring, 5. supporting mechanism, 6. position block, 7. oil engine housing, 8. pilot valve piston, 9. valve rod, 10. modulating valve.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in accompanying drawing; Modulating valve oil engine resetting-mechanism; Comprise the elastomer that is installed between oil engine piston 1 and the oil engine base 2; Said elastomer comprises first spring 3 and second spring 4, and said second spring 4 is set in said first spring 3, and said first spring 3 and second spring 4 are coaxial; Have radial clearance between said first spring 3 and second spring 4, and first spring 3 and second spring 4 satisfy free height and curl up than should equate substantially, intensity equates basically and press and equal highly basically; In the present embodiment, the rotation direction of said first spring 3 and second spring 4 is opposite.
For the ease of installing and locating; Said oil engine piston 1 is provided with the supporting mechanism 5 that is used to install said first spring 3 and second spring 4; Said supporting mechanism 5 is step-like, and this supporting mechanism 5 comprises and is used to the position block 6 that prevents that said second spring 4 from radially sliding.
The working principle of the utility model is following:
The described oil engine piston of the utility model 1, first spring 3 and second spring 4 all are installed in the oil engine housing 7; When needs increase air inflow; The current signal that control system is sent will increase and make the secondary oil of electro-control converter output press liter; Pilot valve piston 8 descends and opens the oil-feed window and make the pressure of oil engine piston 1 top improve, and pilot valve piston 8 and valve rod 9 move down, and opens corresponding modulating valve 10 and air inflow is increased; Simultaneously keep modulating valve 10 lifts owing to mechanical reverse feedback makes oil engine piston 1 reach balance in a certain position, it is stable to guarantee that finally air inflow increases; Move by its resetting-mechanism on oil engine piston 8 and the valve rod 9 and realize, according to standard, the shut-in time of the total travel of oil engine should be less than 0.5 second, and the elasticity that therefore increases resetting-mechanism is most important; The utility model adopts double-deck cluster spring; Comprise first spring 3 and second spring 4 of coaxial package, utilize supporting mechanism 5 to be installed between oil engine piston 1 and the oil engine base 2, the elasticity of resetting-mechanism obviously strengthens; Neither exceeding the design and installation size restrictions; Satisfy again under the situation of burden requirement, form simple and direct, effective, economic modulating valve oil engine resetting-mechanism, make the oil engine valve closing time meet standard.
The utility model is not limited to above-mentioned embodiment, and all are based on the technical conceive of the utility model, and the structural improvement of having done all falls among the protection domain of the utility model.
