Abstract

The utility model discloses a spiral groove plunger single-seat control valve which comprises a valve body, a valve seat, a valve plug and a sleeve. The valve body is provided with a valve cap, the valve seat is arranged inside the valve body, the valve seat is provided with the valve plug, the valve plug contacts with the valve seat, the sleeve is tightly presses on the valve seat, the valve cap is tightly presses on the sleeve, the valve cap is connected on the valve body through a stud and a nut, the valve cap is provided with a filler component, and the valve plug is provided with two crossed spiral grooves which form acute angles with the axial direction of the valve plug in a manufacturing mode, wherein the two crossed spiral grooves are opposite in the rotating direction and symmetrical to be formed. The spiral groove plunger single-seat control valve avoids the fact that fluid generates cavitation corrosion inside the valve, reduces washing of the fluid inside the valve, prolongs the service life of the control valve, and lowers the cost of using and maintaining.

Description

Spiral groove plunger single seat control valve
Technical field
The utility model relates to a kind of small flow single seat control valve, relates in particular to a kind of spiral groove plunger single seat control valve that prevents cavitation erosion.
Background technique
At present, in actual use, under the High Pressure Difference state, be easy to generate high noisy, in order to have solved the reduction noise that former technical products cann't be solved effectively, the patent documentation of publication number CN202431979U has proposed a kind of high hush control valve for small flows, comprise valve body, valve body is provided with valve gap, be provided with the low noise valve seat in the valve body, the low noise valve seat is provided with mangetic core assembly, is provided with guide sleeve between mangetic core assembly and the valve gap, is provided with dentiform gasket between valve gap and the valve body, stuffing box inside is provided with spring, the packing spring bottom is provided with Packing seat, and packing spring top is provided with down filler, middle filler and last filler, last filler upper end is provided with Gland, the Gland upper end is provided with hold-down grid, and the valve rod end of mangetic core assembly is provided with travel indicator.But described patent documentation can't provide the structure that prevents cavitation erosion.
Yet, mostly be solid of rotation such as ball shape, taper greatly at known small flow single seat control valve valve plug.Flow resistance is less relatively, prevents that the cavitation erosion ability is relatively poor, is easily washed away, and life of valve shortens, and use and the maintenance cost increase, and influence is produced.
The model utility content
In order to prolong the working life of small flow single seat control valve, the damage to valve of preventing from cavitating, it is a kind of simple in structure that the utility model purpose is to provide, and cost is relatively low, spiral groove plunger single seat control valve easy to use.
The utility model is a kind of spiral groove plunger single seat control valve, described spiral groove plunger single seat control valve comprises valve body, valve seat, valve plug, sleeve, described valve body is provided with valve gap, described valve seat is arranged in the described valve body, described valve seat is provided with valve plug, described valve plug contacts with described valve seat, described sleeve is pressed on the described valve seat, described valve gap is pressed on the described sleeve, described valve gap is connected on the described valve body by double-screw bolt and nut, at described valve gap filling material assembly is installed, is processed with cross-helicity groove opposite with its axial acutangulate two rotation directions and that be symmetrically formed at described valve plug.
The technological scheme working principle that its technical problem that solves the utility model adopts: be processed with cross-helicity groove design opposite with its axial acutangulate two rotation directions and that be symmetrically formed on the valve plug, under any aperture, valve seat all closely contacts with valve plug.The design of valve plug is fluted, and along with the groove diagonal length on the valve plug constantly changes, groove constantly intersects each other, and fluid passes groove, and circulation area constantly increases, and the groove intersection interim pressure occurs and reduces.Its structure can consume fluid energy effectively, avoids producing pressure drop, can prevent that liquid from producing cavitation and cavitation erosion, reduces high-velocity fluid washing away trim.
The beneficial effects of the utility model are, the cavitation erosion of having avoided fluid to produce in valve has reduced fluid washing away in valve, has prolonged the working life of control valve, and has reduced the operation and maintenance cost.

Fig. 1 is the structure sectional view of the utility model one embodiment's spiral groove plunger single seat control valve.
Fig. 2 is the structural representation of the valve plug in the spiral groove plunger single seat control valve shown in Figure 1.
Fig. 3 is the three-dimensional cutaway view of the utility model one embodiment's spiral groove plunger single seat control valve.
Among the figure: 1-valve body, 2-valve plug, 3-valve seat, 4-sleeve, 5-valve gap, 6-filler assembly.
Embodiment
Below, 1-2 and specific embodiment by reference to the accompanying drawings, the utility model is described in further detail.
Among the embodiment as shown in Figure 1, model utility one embodiment is a kind of spiral groove plunger single seat control valve, comprise valve body 1, valve plug 2, valve seat 3, sleeve 4, described valve body 1 is provided with valve gap 5, described valve seat 3 is arranged in the described valve body 1, valve seat 3 is provided with valve plug 2, valve plug 2 closely contacts with valve seat 3, sleeve 4 is pressed on the valve seat 3, valve gap 5 is pressed on the sleeve, valve gap 5 is connected on the valve body 3 by double-screw bolt, nut, at described valve gap 5 filling material assembly 6 is installed, and has constituted described spiral groove plunger single seat control valve thus.
In example as shown in Figure 2, be processed with cross-helicity groove opposite with its axial acutangulate two rotation directions and that be symmetrically formed at valve plug 2.
The utility model is not limited to above-mentioned mode of execution, and under the situation that does not deviate from flesh and blood of the present utility model, any distortion that those skilled in the art can expect, improvement, replacement all fall into scope of the present utility model.
