Abstract
The utility model relates to a kind of valve, particularly the wear-resisting reduction valve of one.The fork of this device inserts in upper valve body, fork top is by sealing between Sealing and upper valve body, between fork upper-end surface and upper valve body, packing ring is installed, fork upper end connects worm gearing, and fork bottom symmetric design becomes two inverted triangle bodies, and two inverted triangle bodies are set with spring, lower spring end withstands on flap, two inverted triangle body bottoms are inserted in the mounting groove of flap respectively, and on upper flap, symmetry has two sector channels, and upper flap is arranged on upper valve body bottom.The utility model achieves wear-resisting, resistance to erosion, increases the service life, and is applicable to reduced fuel oil lighting project.Overcome existing reduction valve abrasion resistant effect poor, not resistance to erosion, the deficiency that working life is short.
Description
Technical field:
The utility model relates to a kind of valve, particularly the wear-resisting reduction valve of one.
Background technique:
Current all kinds of reduction valve, after using in reduced fuel oil lighting project, the throttle element of valve all can not bear solid, liquid, the washing away of gas three-phase fluid-mixing (coal dust, heavy oil, hydrogen), and abrasion resistant effect is poor, and the working life of valve only has several hours or several days.
Model utility content:
The technical problems to be solved in the utility model is to provide a kind of wear-resisting reduction valve, the arrangement achieves wear-resisting, resistance to erosion, increases the service life, and is applicable to reduced fuel oil lighting project.Overcome existing reduction valve abrasion resistant effect poor, not resistance to erosion, the deficiency that working life is short.
Technical solution adopted in the utility model is: a kind of wear-resisting reduction valve, comprise lower valve body and upper valve body, upper valve body is fixed on lower valve body by fastening stud, and lower valve body lower end and sidewall have passage, upper valve body sidewall has the passage corresponding with lower body wall passage, fork inserts in upper valve body, fork top is by sealing between Sealing and upper valve body, between fork upper-end surface and upper valve body, packing ring is installed, fork upper end connects worm gearing, fork bottom symmetric design becomes two inverted triangle bodies, two inverted triangle bodies are set with spring, lower spring end withstands on flap, two inverted triangle body bottoms are inserted in the mounting groove of flap respectively, on upper flap, symmetry has two sector channels, upper flap is arranged on upper valve body bottom, lower Disc is placed in flap lower end, lower Disc to be arranged in lower valve body and to be sealed by Sealing, on lower Disc, symmetry has two sector channels, fork can drive flap to rotate, when two sector channels on two sector channels of upper flap and lower Disc stagger completely, upper flap and lower Disc seals the lower end passage of time valve body, upper flap and lower Disc all adopt widia to make.
The beneficial effects of the utility model are: the utility model achieves wear-resisting, resistance to erosion, increases the service life, and are applicable to reduced fuel oil lighting project.

Embodiment:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, a kind of wear-resisting reduction valve, comprise lower valve body 1 and upper valve body 2, upper valve body 2 is fixed on lower valve body 1 by fastening stud 7, lower valve body 1 lower end and sidewall have passage, upper valve body 2 sidewall has the passage corresponding with lower valve body 1 side wall channels, fork 3 inserts in upper valve body 2, fork 3 top is by sealing between Sealing 9 and upper valve body 2, packing ring 6 is installed between fork 3 upper-end surface and upper valve body 2, fork 3 upper end connects worm gearing 8, fork 3 bottom symmetric design becomes two inverted triangle bodies, two inverted triangle bodies are set with spring, lower spring end withstands on flap 5, two inverted triangle body bottoms are inserted in the mounting groove of flap 5 respectively, on upper flap 5, symmetry has two sector channels, upper flap 5 is arranged on upper valve body 2 bottom, lower Disc 4 is placed in flap 5 lower end, lower Disc 4 to be arranged in lower valve body 1 and to be sealed by Sealing, on lower Disc 4, symmetry has two sector channels, fork 3 can drive flap 5 to rotate, when two sector channels on two sector channels of upper flap 5 and lower Disc 4 stagger completely, upper flap 5 and lower Disc 4 seals the lower end passage of time valve body 1, upper flap 5 and lower Disc 4 all adopt widia to make.
Because upper flap 5 and lower Disc 4 all adopt widia to make, thus there is high hardness, good wear resistance, red hardness (performance of high hardness can be kept at namely higher temperature) and certain resistance to flexure.
During use, from lower valve body 1 side wall channels feed liquor, from lower valve body 1 lower end passage fluid, rotate fork 3 and then drive upper flap 5 to rotate, by regulate two sector channels of upper flap 5 to be connected with the sector channel of two on lower Disc 4 area size so that regulate feed liquor how many, if two sector channels on two sector channels of upper flap 5 and lower Disc 4 stagger completely, then go up the lower end passage that flap 5 and lower Disc 4 seal lower valve body 1.
Be understandable that, above about specific descriptions of the present utility model, the technological scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
