Abstract
The utility model relates to an eliminate cone valve of mechanical noise, including being cylindric valve body, being located fluid passage in the valve body, be located fluid passage's case, the case is the cone valve core, and the cone valve core is the line contact with contact department of valve body to form good linear sealing, improve its sealed effect, the rear end of case is provided with the valve rod, and one side is provided with a damping tail on the valve rod, is provided with the 2nd damping tail at the opposite side of valve rod, just a damping tail is the same with the 2nd damping tail size, and the symmetry sets up the both sides at the valve rod. The utility model has the advantages of simple structure and reasonable design, be connected with a damping tail and the 2nd damping tail in the case rear end through the valve rod, can make cone valve core keep balance in the motion process, prevent the radial vibration to the noise reduction improves the performance of cone valve.
Description
Technical field
The utility model relates to valve class field, particularly relates to a kind of cone valve eliminating mechanicalness noise.
Background technique
Hydrovalve is the Automation Elements of a kind of pressure oil operation, and it is by the control of voltage distribution valve pressure oil, and usual and electromagnetic distributing valve combinationally uses, and can be used for the break-make of distant control water power plant oil, gas, water piping system.Be usually used in the oil circuits such as clamping, control, lubrication.Hydrovalve is divided into directional control valve, Flow valve, pressure valve etc.Hydrovalve plays a very important role in hydraulic system, any one hydraulic system, no matter how simple it is, all hydrovalve can not be lacked, the hydraulic mechanical equipment of same technique object, by various combination and the use of hydrovalve, the distinct multiple hydraulic system scheme of oil channel structures can be formed, therefore hydrovalve is kind and maximum, most widely used general, the most active element of specification in hydraulics.The basic structure of hydrovalve mainly comprises the operating control mechanism that spool, valve body and driving spool do relative motion in valve body, the structural type of spool has multiple, valve body offers the valve body hole or valve seat orifice that coordinate with spool, also have external oil pipe into and out of hydraulic fluid port, the operating mechanism of spool has hand-adjusting type, mechanical type, electrodynamic type and hydrodynamic or electric hydrodynamic.In use, due to the effect of hydraulic power, radial energy imbalance can be there is, thus cause cone valve to occur vibration, produce noise in cone valve.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of cone valve eliminating mechanicalness noise, by being provided with two symmetrical weakening tails, can reduce vibration, reducing noise.
The utility model is achieved through the following technical solutions:
A kind of cone valve eliminating mechanicalness noise, comprise cylindrical valve body, be positioned at the fluid passage of described valve body, be positioned at the spool of fluid passage, described spool is poppet valve core, the contacting point of poppet valve core and valve body is linear contact lay, thus form good linear sealing, improve its sealing effect, the rear end of described spool is provided with valve rod, and side is provided with the first weakening tail on described valve rod, the opposite side of valve rod is provided with the second weakening tail, and described first weakening tail is identical with the second weakening tail size, is symmetricly set on the both sides of valve rod.
As optimal technical scheme of the present utility model, the cross section of described valve rod is circular.
As optimal technical scheme of the present utility model, described first weakening tail and the second weakening tail are inclined on valve rod.
As optimal technical scheme of the present utility model, the angle of described first weakening tail and substantially horizontal is 30 degree-60 and spends.
As optimal technical scheme of the present utility model, described valve body adopts Austenitic Stainless Steel to make, and anodization is carried out on surface, and described spool is base material with metal, is that the composite material on top layer is made with pottery.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the first weakening tail and the second weakening tail is connected with by valve rod in spool rear end, can make poppet valve core in movement process, keep balance, prevent radial vibration, thus reduction noise, improve the usability of cone valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of cone valve eliminating mechanicalness noise, comprise cylindrical valve body 1, be positioned at the fluid passage 2 of described valve body 1, be positioned at the spool 3 of fluid passage 2, described spool 3 is poppet valve core, the contacting point of poppet valve core and valve body 1 is linear contact lay, thus form good linear sealing, improve its sealing effect, the rear end of described spool 3 is provided with valve rod 4, and side is provided with the first weakening tail 5 on described valve rod 4, the opposite side of valve rod 4 is provided with the second weakening tail 6, and described first weakening tail 5 is identical with the second weakening tail 6 size, be symmetricly set on the both sides of valve rod 4.Be connected with the first weakening tail and the second weakening tail in spool rear end by valve rod, can make poppet valve core in movement process, keep balance, prevent radial vibration, thus reduce noise, improve the usability of cone valve.
The cross section of described valve rod 4 is circular, and described first weakening tail 5 and the second weakening tail 6 are inclined on valve rod 4, and described first weakening tail 5 is 30 degree-60 with the angle of substantially horizontal and spends.
In the present embodiment: described valve body 1 adopts Austenitic Stainless Steel to make, and anodization is carried out on surface, effectively can prevent corrosion, and the process treating such as chrome-faced, nickel, molybdenum, magnesium are carried out to Austenitic Stainless Steel, also can improve the corrosion protection abrasion resistant performance of material.
Described spool 3 is base material with metal, is that the composite material on top layer is made with pottery, so both remains the obdurability of metal and the high hardness of pottery and excellent wear-resistant corrosion resistance, overcome again the fragility of pottery.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
