Abstract
The utility model relates to a pressure adjustable relief valve, including casing, slide valve, spring, guide bolt, adjusting screw, on the oil circuit of slide valve setting in the casing and can be at the casing internal motion, a spring end pressure on the slide valve, another end pressure on the spring holder, the guide bolt install on the casing, the guide is provided with adjusting screw through the screw thread on the bolt, adjusting screw one end push up on the spring holder, the other end exposes outside the relief valve through the guide bolt. The utility model discloses at adjust pressure's in -process, need not decompose the relief valve, only make through the rotation regulation screw and realized required function to need not be equipped with a large amount of gasket etc. Have the characteristics that accommodation process is simple, the regulation is convenient, with low costs, save time.
Description
Technical field
The utility model relates to a kind of Decompression valves, especially a kind of Decompression valves of pressure adjustable.
Background technique
In mechanical field, lubricating oil, by being distributed to after lubricating oil pump in each system, realizes function that is lubricious and cooling.And generally, the lubricating oil pressure required by each several part is different, after lubricating oil is pressurizeed by lubricating oil pump, pressure to be regulated, the usage requirement at each position could be met.Therefore, under most cases, lubricating oil oil circuit can be provided with Decompression valves usually, by the effect of Decompression valves, realize the adjustment of lubricating oil pressure.Decompression valves is generally the check valve be arranged on oil circuit, arranges initial pressure value by the spring of inside, i.e. cracking pressure value.When lubricating oil pressure is greater than initial value, just can open check valve, a part of lubricating oil flows out from check valve, reaches the object of pressure release.And due to each intrasystem pressure requirements difference, therefore need to regulate the cracking pressure of Decompression valves itself, normally Decompression valves is decomposed, then by the mode at spring seat position increase and decrease pad, thus regulate the pressure of pressure adjusting spring, and then regulate lubricating oil vent pressure.Adjustment process is loaded down with trivial details, adjustment is inconvenient, and needs to be equipped with a large amount of pads etc., and cost is high, loses time.
Summary of the invention
The purpose of this utility model is to provide a kind of Decompression valves of pressure adjustable, can realize the requirement that adjustment process is simple, easy to adjust, and has low, the time saving feature of cost.
The technical solution of the utility model is, the Decompression valves of pressure adjustable is arranged on oil circuit, comprise housing 7, slide-valve 6, spring 5, spring seat 4, guide bolt 3, adjusting screw 1, slide-valve 6 is arranged on the oil circuit in housing 7 and also can moves in housing 7, the motion of slide-valve 6 achieves the unlatching of oil circuit and closes, spring 5 one end is pressed on slide-valve 6, the other end is pressed on spring seat 4, described guiding bolt 3 is arranged on housing 7, guide on bolt 3 and screw thread is provided with adjusting screw 1, adjusting screw 1 one end withstands on spring seat 4, the other end is exposed to outside Decompression valves by guiding bolt 3.
The utility model, by being provided with adjusting screw on Decompression valves, by turning adjusting screw, makes the axial motion that mouth is followed closely, and then the motion of band flexible spring seat.The motion of spring seat achieves the adjustment of amount of spring compression, thus meets the regulatory demand of the cracking pressure of Decompression valves.The utility model is in the process regulating pressure, Decompression valves is not needed to decompose, make to achieve required function by means of only turning adjusting screw, and do not need to be equipped with a large amount of pad etc., have that adjustment process is simple, easy to adjust, cost is low, time saving feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, the Decompression valves of pressure adjustable is arranged on oil circuit, comprise housing 7, slide-valve 6, spring 5, spring seat 4, guide bolt 3, adjusting screw 1, slide-valve 6 is arranged on the oil circuit in housing 7 and also can moves in housing 7, the motion of slide-valve 6 achieves the unlatching of oil circuit and closes, spring 5 one end is pressed on slide-valve 6, the other end is pressed on spring seat 4, described guiding bolt 3 is arranged on housing 7, guide on bolt 3 and screw thread is provided with adjusting screw 1, adjusting screw 1 one end withstands on spring seat 4, the other end is exposed to outside Decompression valves by guiding bolt 3.
