The technological scheme that the utility model adopts is: a kind of pressure regulator valve, comprises valve body, valve seat, spool and valve rod, and its feature is, the centre of spool is provided with the central blind hole of upward opening, and the main body of this central blind hole is straight hole, and upper opening is the enlarging conical surface; The bottom of valve rod is straight bar section, and sphere is expanded as in the upper end of straight bar section; The straight bar section of valve rod inserts in the straight hole of spool, the sphere of valve rod and the enlarging conical surface of spool tangent.
Above-mentioned pressure regulator valve, wherein, valve seat has a central through bore, and the middle part of this central through bore is straight hole, and the upper/lower terminal aperture of this central through bore is the enlarging conical surface; Spool is made up of hypomere, stage casing and epimere; The side face of hypomere is the conical surface; The shape line of the section in stage casing is one section of curve close to straight line; Epimere has can be tangent and form the surface of contact of potted line with the enlarging conical surface in aperture, valve seat upper end, and this surface of contact is spherically, and crossing with stage casing.
The utility model at least has the following advantages:
1. valve rod of the present utility model and spool can be thrown off mutually, and adopt the conical surface and location at spherical surface, and under action of a fluid, spool can realize from centering relative to valve seat, thus eliminate spool and valve seat bias produce occur in uttering long and high-pitched sounds of restriction;
2. spool of the present utility model and valve seat construction have under full flow (or close to full flow) operating mode, and upstream pressure, with the feature of the aperture linear change of valve, is easy to the characteristic of mild stability contorting and adjustment.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the structural representations of the pressure regulator valve according to the utility model embodiment.
Fig. 3, Fig. 4, Fig. 5 are structure and the working state schematic representation of valve seat, valve rod and spool according to the utility model one embodiment.
Fig. 6 is the structural representation of the spool according to the utility model one embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Please refer to the drawing 1 to Fig. 6.According to the pressure regulator valve of the utility model one embodiment, comprise upper valve body 1, lower valve body 2, valve seat 3, valve rod 4 and spool 5.
Valve seat 3 wherein adopts upright tubular structure, has a central through bore.The middle part of this central through bore is straight hole 31, and the upper/lower terminal aperture of this central through bore is the enlarging conical surface 32,33.Spool 5 is made up of hypomere 51, stage casing 52 and epimere 53.The side face of hypomere 51 is the conical surface, and the shape line of the section in stage casing 52 is in the curve close to straight line, and epimere 53 has can be tangent and form the surface of contact 531 of potted line with the enlarging conical surface 32 in aperture, valve seat upper end, and surface of contact 531 is spherically, and crossing with stage casing 52.
Be provided with the central blind hole of upward opening in the centre of spool 5, the main body of this central blind hole is straight hole 55, and upper opening is the enlarging conical surface 56.The bottom of valve rod 4 is straight bar section 41, and sphere 42 is expanded as in straight bar section upper end.The straight bar section 41 of valve rod inserts in the straight hole 55 of spool, and the sphere 42 of valve rod is tangent with the enlarging conical surface 56 of spool.Compared with prior art, valve rod 4 of the present utility model can be thrown off mutually with spool 5, and adopt the conical surface and location at spherical surface, under the effect of current, spool 5 can realize from centering relative to valve seat 3, thus eliminating the uttering long and high-pitched sounds at restriction of spool and the generation of valve seat bias, the hydraulic characteristic of design anticipation also can realize.
Adopt seam to be located by connecting between upper valve body 1 and lower valve body 2, form the valve body of this pressure regulator valve.Adopt the upper and lower valve body structure that this seam is located, pressure regulator valve volume is little, and intensity is high, and Sealing is few, simple and reliable, and installation and maintenance are easy.Be provided with medium entrance 6 in the bottom of lower valve body 2, be provided with media outlet 7 in the side of upper valve body 1.
Pressure regulator valve of the present utility model can make the structure of manual tune, as shown in Figure 1, handles valve rod by handle 8.Can also electric actuator be connected, as shown in Figure 2, handle valve rod by drive unit 9, realize Intelligent adjustment under control of the computer.Oil sealing 13 and block 14 is also show in Fig. 2.
As shown in Figure 3, when the cone-shaped hypomere 51 of spool 5 coordinates with the straight hole 31 of valve seat, form low pressure Circulation Area; Low pressure Circulation Area passage section is large, and when liquid passes through, flow resistance is very little.
As shown in Figure 4, when shape line be coordinate with the straight hole 31 of valve seat 3 close to the stage casing 52 of the curve of straight line time, mineralization pressure regulatory region; Pressure regulatory region passage section rate of change from large to small, and the rule that the cube meeting the gap in pressure differential deltap p and annular flow cross section before and after throttle valve is inversely proportional to, thus realize the aperture linear change of upstream pressure with valve.
As shown in Figure 6, the curve close to straight line in stage casing 52 describes in order to minor function: y=d/2-[r-(r
