Abstract
The utility model relates to a check valve device. The check valve device is characterized in that an oil inlet is formed on a shell of the device, an outlet adapter coupling component is arranged on the shell and is provided with an oil outlet, a lower spring pushing seat is arranged in the shell, a through hole penetrating through two sides is formed on the lower spring pushing seat, a draw bar component capable of axially moving is penetrated in the middle of the lower spring pushing seat, one end of the draw bar component, which is close to the oil outlet, is provided with steps and is in contact with the lower spring pushing seat, one end of the draw bar component, which is close to the oil outlet, is provided with a compression spring, one end of the compression spring is pressed on the lower spring pushing seat, the other end of the compression spring is pressed on an upper spring pushing seat which is fixed on the draw bar component, and adjustable pads arranged between the compression spring and the upper spring pushing seat. The check valve device has the advantages that the same set of structure can meet different pressure requirements through grading assembly of the adjustable pads, and the opening pressure of a valve is ensured to be stable by a method of permitting grinding of the adjustable pads.
Description
Technical field
The utility model relates to a kind of check valve device.
Background technique
In the machinery of lubricating by lubricating oil, for keeping the oil level in fuel tank or closing a certain oil circuit when not required, often need to arrange check valve, make the lubricating oil can only one-way flow when work.Existing check valve device is generally that structure is fixed, flow of oil is when check valve, when pressure reaches fixed value, check valve is opened, this kind structure exists cracking pressure unstable, and pressure is not easy to debugging, and the individual event valve of same structure is regulated pressure range and fixed, and can not realize adjusting cracking pressure by a relatively large margin.
Summary of the invention
To be solved in the utility model is a kind of check valve of invention, and its cracking pressure is stable, pressure is easy to debugging, and can realize significantly regulating cracking pressure, adapts to the needs of different machineries.
the technical solution of the utility model is: device comprises housing, Compress Spring, footstock under spring, footstock on spring, spacer, rod assembly, the outlet transfer element, be provided with oiler on described housing, the outlet transfer element is arranged on housing and is provided with oil outlet, described oiler and oil outlet all communicate with enclosure interior, footstock under spring is installed in housing, be provided with the through hole that connects both sides under described spring on footstock, the centre is installed with can axially movable rod assembly, one end of the close oil outlet of described rod assembly is provided with step and contacts with footstock under spring, an end near oiler is provided with Compress Spring, Compress Spring one side pressure is under spring on footstock, the other end be pressed in the fixing spring of rod assembly on footstock, be provided with spacer between footstock on Compress Spring and spring, described spacer combines for several thin slices, the position that under described spring, footstock contacts with the step of rod assembly is cone-shaped inner hole, the step part of rod assembly 7 is the rubber that is glued on the bar assembly.
By the adjustment to the elasticity coefficient of the spacer quantity in the utility model and Compress Spring, can satisfy different usage requirements.
The utlity model has obvious technique effect: by with spacer classification assembling, make the valve cracking pressure be easy to debug to acceptability limit, and increased valve cracking pressure scope, make same set of structure can satisfy the demand of different pressures.And by allowing the method for reconditioning spacer, can make the valve cracking pressure be stabilized in the intermediate value of cracking pressure, avoid making cracking pressure exceed predetermined range because the elastic coefficient changes in follow-up work, guarantee the stable of valve cracking pressure.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
as shown in Figure 1, device comprises housing 1, Compress Spring 2, under spring, footstock 3, on spring, footstock 4, spacer 5, rod assembly 6, outlet transfer element 7, be provided with oiler on described housing 1, outlet transfer element 7 is arranged on housing 1 and is provided with oil outlet, described oiler and oil outlet all communicate with housing 1 inside, footstock 3 under spring is installed in housing 1, be provided with the through hole that connects both sides under described spring on footstock 3, the centre is installed with can axially movable rod assembly 6, one end of the close oil outlet of described rod assembly 6 is provided with step and contacts with footstock 3 under spring, an end near oiler is provided with Compress Spring 2, Compress Spring 2 one side pressures are under spring on footstock 3, the other end be pressed in the fixing spring of rod assembly 6 on footstock 4, be provided with spacer 5 on Compress Spring 2 and spring between footstock 4, described spacer 5 combines for several thin slices, the position that under described spring, footstock 3 contacts with the step of rod assembly 6 is cone-shaped inner hole, the step part of rod assembly 6 is the rubber that is glued on bar assembly 6.
in use, with the check valve device by flow of oil to correctly being arranged in oil circuit, lubricating oil enters housing 1 inner chamber by oiler, part lubricating oil footstock 4 both sides mineralization pressures on spring, the through hole of another part by footstock under spring 3 acts on mineralization pressure on the rubber part of rod assembly 6, when lubricating oil pressure reaches certain value, act on that on spring, the upper lubricating oil pressure of footstock 4 and rod assembly 6 promotes footstock on spring 4 and rod assembly 6 in the lump, rod assembly 6 moves vertically, under rubber part on rod assembly 6 and spring, the cone-shaped inner hole point of contact of footstock 3 separates, lubricating oil flows to outlet transfer element 7 by footstock under spring 3 and the opening that rod assembly 6 forms, oil outlet on outlet transfer element 7 flows in oil circuit.After under rod assembly 6 and spring, footstock 3 openings reached certain value, lubricating oil pressure and openings of sizes reached transient equiliblium, i.e. the regulation cracking pressure scope of valve.In different usage requirement situations, quantity that can be by regulating spacer and the elasticity coefficient of spring are adjusted the cracking pressure of valve.
