Abstract
The utility model relates to a triangle slot type check valve, including the internal fluid channel's that has its axis extend of edge who confirms valve body, set up the case in valve body internal fluid channel, seted up the spring cavity along its axial lead direction in the case install the spring in the spring cavity, the one end of spring top is supported on the bottom surface of spring cavity, and the case is the cone valve core, the triangular groove has been offered along its axial lead orientation to the intermediate position of the preceding terminal surface of case, and the apex angle department of triangular groove is the arc and describes, and two inner wall departments of triangular groove are provided with the arch, it is protruding semi -circular. The utility model discloses a be provided with the triangular groove to being provided with semi -circular arch on the inner wall of triangular groove, can strikeing the ranging back to the cavitation erosion of concentrating like this and go out, change cavitation erosion production position, the most serious excess flow valve mouth of cavitation erosion in the protection check valve can also reduce the cavitation erosion and damaging intensity.
Description
Technical field
The utility model relates to valve class technical field, particularly relates to a kind of triangular groove type check valve.
Background technology
Hydraulic valve is the Automation Elements of a kind of pressure oil operation, and it is controlled by distributing valve pressure oil, is generally applied in combination with electromagnetic distributing valve, can be used for far distance controlled power station oil, the break-make of gas and water pipe-line system.Be usually used in clamping, control, the oil circuit such as lubrication.Hydraulic valve is divided into direction valve, flow valve, pressure valve etc..Check valve belongs to the one of direction valve, and check valve is mainly used to control liquid flow one way flow in hydraulic system, and conventional check valve is divided into common check valve and hydraulic control one-way valve two class.Common check valve effect in hydraulic system is only to allow liquid flow to pass through along one direction of pipeline, and the flowing in another direction is then cut off, and according to the difference of runner, common check valve has through type and two kinds of typical structures of right-angle type.Straight check valve liquid flow import and export runner and communicate, therefore generally tubular type is installed and is connected (being connected in system with pipe joint by the Taper Pipe at valve body two ends or straight pipe thread hole).The spool of check valve has ball-valve type and two kinds of forms of cone valve type.During the use of check valve, can produce cavitation, cavitation erosion produces the erosion of two kinds of forms on spool and valve seat: one is large-sized pit, and another kind is the pit that some are less, is the impact cumulative function more weak by some intensity.
Utility model content
The utility model is in order to overcome deficiency of the prior art, it is provided that a kind of triangular groove type check valve.
The utility model is to be achieved through the following technical solutions:
A kind of triangular groove type check valve, including with the valve body of an internal fluid channels extended along its axis determined, the spool that is arranged in valve inner fluid passage, spring cavity is offered along its direction of axis line in described spool, in described spring cavity, spring is installed, one end contact of spring is on the bottom surface of spring cavity, spool is poppet valve core, the centre position of the front end face of described spool offers triangular groove along its direction of axis line, curved shape at the drift angle of triangular groove, and at two inwalls of described triangular groove, it is provided with projection, described protruding semicircle.
As optimal technical scheme of the present utility model, described spring is cylindrical spring or taper spring.
As optimal technical scheme of the present utility model, described valve body uses austenitic stainless steel to make, and described spool is with metal as base material, and the composite with pottery as top layer is made.
As optimal technical scheme of the present utility model, the lower end of described valve body offers the inlet communicated with internal fluid channels, and the two side of inlet is provided with screw thread.
Compared with prior art; the beneficial effects of the utility model are: the utility model is provided by triangular groove; and on the inwall of triangular groove, it is provided with semi-cylindrical hill; so the cavitation shock concentrated can be extended back away; change cavitation erosion generating unit; the excess flow valve mouth cavitating the most serious in protection check valve, it is also possible to reduce cavitation erosion and damage intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, 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, is not used to limit the utility model.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of triangular groove type check valve, including with the valve body 1 of an internal fluid channels 2 extended along its axis determined, the spool 3 that is arranged in valve body 1 internal fluid channels 2, spring cavity 4 is offered along its direction of axis line in described spool 3, in described spring cavity 4, spring 5 is installed, one end contact of spring 5 is on the bottom surface of spring cavity 4, described spring 5 is cylindrical spring or taper spring, spool 3 is poppet valve core, the lower end of described valve body 1 offers the inlet 8 communicated with internal fluid channels 2, and the two side of inlet 8 is provided with screw thread.
The centre position of the front end face of described spool 3 offers triangular groove 6 along its direction of axis line, curved shape at the drift angle of triangular groove 6, and is provided with protruding 7 at two inwalls of described triangular groove 6, described protruding 7 semicirculars in shape.It is provided by triangular groove 6; and on the inwall of triangular groove 6, it is provided with semi-cylindrical hill 7, so the cavitation shock concentrated can be extended back away, change cavitation erosion generating unit; the excess flow valve mouth cavitating the most serious in protection check valve, it is also possible to reduce cavitation erosion and damage intensity.
Described valve body 1 uses austenitic stainless steel to make, and surface carries out anodization, can effectively prevent corrosion, and austenitic stainless steel carries out the PROCESS FOR TREATMENT such as chrome-faced, nickel, molybdenum, magnesium, it is also possible to improve the corrosion protection abrasion resistant performance of material.
Described spool 3 is with metal as base material, and the composite with pottery as top layer is made, and has the most both remained the obdurability of metal and the high rigidity of pottery and excellent wear-resistant corrosion resistance, has 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 any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
