Abstract
The invention relates to a check valve device. An oil inlet is arranged on a casing of the check valve device, and an outlet switching element is arranged on the casing and provided with an oil outlet. A spring lower footstock is arranged in the casing, a through hole penetrating through two sides is arranged on the spring lower footstock, a pull rod assembly capable of axially moving is arranged in the middle of the spring lower footstock in penetrating mode, one end of the pull rod assembly close to the oil outlet is provided with a step and is contacted with the spring lower footstock, a compression spring is arranged at one end of the pull rod assembly close to the oil inlet, one end of the compression spring is pressed on the spring lower footstock, the other end of the compression spring is pressed on a spring upper footstock fixedly connected with the pull rod assembly, and adjusting pads are arranged between the compression spring and the spring upper footstock. The check valve device can meet different pressure requirements through the same structure by assembling the adjusting pads in grading mode, and ensures valve opening pressure stability by aid of an adjusting pad grinding method.
Description
Technical field
The present invention relates to a kind of check valve device.
Background technique
In the machinery lubricated by lubricating oil, for keeping the oil level in the 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 generally is 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 by this invention 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.
Technological scheme of the present invention is: device comprises housing, Compress Spring, footstock under the spring, footstock on the spring, spacer, rod assembly, the outlet transfer element, be provided with oiler on the described housing, the outlet transfer element is installed on the housing and is provided with oil outlet, described oiler and oil outlet all communicate with enclosure interior, footstock under the spring is installed in housing, be provided with the through hole that connects both sides under the described spring on the 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 the spring, end near oiler is provided with Compress Spring, Compress Spring one side pressure is under spring on the footstock, the other end be pressed in the fixing spring of rod assembly on the footstock, be provided with spacer between the footstock on Compress Spring and the spring, described spacer combines for several thin slices, the position that footstock contacts with the step of rod assembly under the described spring is cone-shaped inner hole, and 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 among the present invention and Compress Spring, can satisfy different usage requirements.
The present invention 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, so that 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 the follow-up work, guarantee the stable of valve cracking pressure.
Description of drawings
Fig. 1 is schematic representation of the present invention.
Embodiment
As shown in Figure 1, device comprises housing 1, Compress Spring 2, footstock 3 under the spring, footstock 4 on the spring, spacer 5, rod assembly 6, outlet transfer element 7, be provided with oiler on the described housing 1, outlet transfer element 7 is installed on the housing 1 and is provided with oil outlet, described oiler and oil outlet all communicate with housing 1 inside, footstock 3 under the spring is installed in housing 1, be provided with the through hole that connects both sides under the described spring on the 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 the spring, end near oiler is provided with Compress Spring 2, Compress Spring 2 one side pressures are under spring on the footstock 3, the other end be pressed in the fixing spring of rod assembly 6 on the footstock 4, be provided with spacer 5 on Compress Spring 2 and the spring between the footstock 4, described spacer 5 combines for several thin slices, the position that footstock 3 contacts with the step of rod assembly 6 under the described spring is cone-shaped inner hole, and the step part of rod assembly 6 is the rubber that is glued on the bar assembly 6.
In use, with the check valve device by flow of oil to correctly being installed in the 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 the spring 3 acts on mineralization pressure on the rubber part of rod assembly 6, when lubricating oil pressure reaches certain value, act on that the upper lubricating oil pressure of footstock 4 and rod assembly 6 promotes footstock on the spring 4 and rod assembly 6 in the lump on the spring, rod assembly 6 is mobile vertically, the cone-shaped inner hole point of contact of footstock 3 separates under rubber part on the rod assembly 6 and the spring, lubricating oil flows to outlet transfer element 7 by footstock under the spring 3 and the opening that rod assembly 6 forms, and the oil outlet on outlet transfer element 7 flows in the oil circuit.After footstock 3 openings reached certain value under rod assembly 6 and the spring, 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.
