Description
Technical field
The utility model relates to a kind of outlet of plunger pump one-way valve, particularly a kind of one-way valve containing guiding element.
Background technique
One-way valve is in hydraulic system, prevents the device of fluid reverse flow.Existing one-way valve is made up of valve body, valve seat, spool and spring element usually, and elastic element used is generally normal spiral spring.In the process that this one-way valve uses in reality, mainly there is following problem: 1, under oil liquid pressure effect, spool infinite place, without guiding, and spool opening travel is comparatively large, easily makes one-way valve produce vibration and noise; 2, normal spiral spring stress level is higher, causes spring limited for working life, thus affects reliability and the service time of one-way valve.
Summary of the invention
In order to solve prior art Problems existing and deficiency, the utility model provides a kind of under oil liquid pressure effect, and spool opens limited location, and fluid has guiding, disc vibration reduce and spring working life higher check valve apparatus.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of one-way valve, comprise valve body, valve seat, slide the spool be arranged in valve body, described valve body is at least provided with one and crosses oil groove, described valve seat is provided with the through hole matched with spool, described spool one end is arranged in through hole, its structural feature is, the described spool the other end is provided with guiding element, be provided with at least one between described guiding element and valve body and cross oil-gap, or described guiding element is provided with at least one oil outlet, described guiding element is connected to valve body by elastic element.The object that arranges of described guiding element is: when spool is opened under oil liquid pressure effect, guiding element limits by the motion of its longitudinal length to spool, avoid spool opening travel larger, avoid the generation of spool under oil liquid pressure effect to rotate simultaneously, then the vibration produced by spool and the noise minimization caused due to disc vibration, guiding element better can realize the steady output of fluid simultaneously.
Described guiding element is made up of with the first lug boss being connected clamping part clamping part, and when described clamping part contacts with valve body, described oil-through hole is arranged on the clamping part of guiding element.Under oil liquid pressure effect, spool is opened, and after fluid flows to the valve chamber after spool, then flows to valve body along the oil-through hole of clamping part and crosses oil groove, thus realize the directional stream-guidance of fluid.As preferred further, described clamping part can be symmetrical arranged oil-through hole.
When the widest part distance of described clamping part is less than valve block internal diameter, described oil-gap of crossing is arranged between the clamping part of guiding element and valve body, under oil liquid pressure effect, spool is opened, and fluid can flow to valve body along the oil-gap excessively between guiding element clamping part and valve body and cross oil groove.
As preferably, described elastic element is flat springs.Under identical stress level, the stress level of flat springs is lower than normal spiral spring, therefore the working life of flat springs is higher than normal spiral spring.Adopt flat springs to replace helical spring, one-way valve reliability and service time can be improved preferably.
As preferably, described first lug boss is provided with the second lug boss, and described second lug boss is coupled laterally to valve body by flat springs.The object that arranges of described second lug boss is, the installation of guiding element and valve body is located and is more prone to.
The utility model compared with the existing technology has the following advantages and effect: 1, be provided with guiding element in one end of spool, and when spool is opened, guiding element can carry out spacing to the motion of spool, avoids spool opening travel larger; 2, guiding element better can realize the steady output of fluid; 3, arranging of guiding element can reduce the vibration and noise that one-way valve in use produces; 4, the use of flat springs, improves reliability and the working life of one-way valve.
