Description
Technical field
The utility model relates to a kind of hydraulic fittings, especially relates to a kind of from compressing valve body structure.
Background technique
Valve be utilize a movable part come open and close or part block opening or passage, fluid can be flowed out, blocks or adjusted a kind of device.Hydrovalve of the prior art, adopts steel ball or metal cone guiding valve to contact with the aperture of metal seat valve under spring and fluid pressure action as spool and compresses.Operationally, the fluid come from valve body front fluid passage backs down spool under the effect of the pressure and flows out valve body.When decompression or after applying directional pressure, valve core reset, valve body is closed.
The restricted lifetime of spring, regular Compress Spring or spring are in compressive state for a long time, all can affect the working life of spring.Once fatigue damage appears in spring, its elasticity coefficient will change, and directly affects the receptance of spring.Now, control the flow of fluid by spring, the folding of control valve body will there will be larger deviation.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of from compressing valve body structure, and the structure of self can be utilized to carry out the folding of control valve body.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of from compressing valve body structure, comprise valve seat and core member, described valve seat is provided with the valve port running through lower planes, described valve port comprises columned upper valve port and lower valve port, the bore of described upper valve port is greater than the predetermined value of the bore one of lower valve port, described core member is stuck in valve port and the upper end of core member passes valve port, the upper end of described core member is provided with water inlet, described water inlet has run through the bottom surface of core member, described core member comprises the upper valve core being positioned at valve port upper end and the lower valve core being positioned at lower valve port lower end, described upper valve core and described upper valve mouth structure adapt and are sealed upper valve port upper end, described lower valve core is stuck in lower valve port lower ending opening place and is sealed by lower valve port lower ending opening, described upper valve core is connected by connecting core with between lower valve core, the below of described core member is provided with groove, the middle part of described valve seat is provided with water outlet,
Fluid arrives groove after entering spool by water inlet, and fluid enters valve port by the lower ending opening of lower valve port, and fluid is flowed out by the water outlet on valve seat.
Described connecting core is cylindrical structure, the diameter length of described connecting core is less than the diameter length of lower valve port, the diameter length of described upper valve core equals the diameter length of valve port, described lower valve core is truncated cone shape structure, the diameter length of the upper-end surface of described lower valve core equals the diameter length of connecting core, and the diameter length of the lower end surface of described lower valve core is greater than the diameter length of lower valve port.The size of valve design chipware like this and valve port can ensure structure of the present utility model.
The upper end of described upper valve core passes the upper-end surface of valve port, and the opening of described water inlet is positioned at the upper side of upper valve core.Water inlet opening is arranged on side and ensure that fluency into water.
Described water outlet is positioned at the side of described connecting core.After the setting of water outlet position ensure that fluid enters valve port, the power that core member is subject to can produce one from the effect compressed.
Be provided with spring in described groove, described spring is connected with the bottom surface of lower valve core, and described lower valve core is movable in groove under the promotion of spring.Arranging spring is motion in order to coordinate spool, can control valve core movement more flexibly.And spring is not set also does not affect use of the present utility model.
The top of described core member is provided with push rod, and described push rod is connected with the upper-end contact of upper valve core.Push rod is used for the decrement of control spring, controls the fluid flow by valve port thus.
Compared with prior art, the utility model has the advantage of that fluid passes through the water inlet be arranged on upper valve core and enters spool, and water inlet has run through whole core member, the bottom surface from lower valve core is flowed into groove by fluid.Hydraulic pressure can make core member move down, and opens lower valve port.Fluid enters valve port by the lower ending opening place of valve port, and is flowed out by the water outlet of valve seat side.Upper valve core one thrust upwards can be applied to after fluid enters valve port, be applied to the pressure that lower valve core one is downward simultaneously.And the bore of upper valve port is greater than the bore of lower valve port, therefore in valve port, be greater than lower valve core with the surface of contact upper valve core of fluid contact, thrust is upwards greater than downward pressure.Valve core is under the effect of thrust, and can move up close port.The utility model, when the effect without spring, achieves from compressing, and namely long-time use also can not have influence on the folding of valve port.
