Abstract
The invention discloses a special ultrahigh pressure cone valve for coal slurry. The special ultrahigh pressure cone valve for the coal slurry comprises a valve body, a valve cap, a support ring, a left valve seat, a ball body, a valve rod, a right valve seat, a stuffing box and a gland, wherein the valve cap is fixed with the valve body through at least one bolt; the supporting ring is located between the left valve seat and the valve cap; the ball body is located in a valve cavity formed by the valve body and the valve cap; the left valve seat and the right valve seat are located on two sides of the ball body; the valve rod and the ball body are perpendicularly connected; the stuffing box is located on the valve body; and the gland is located above the stuffing box. With the adoption of the special ultrahigh pressure cone valve for the coal slurry, due to an effect that the flow rate and the pressure of fluid are changed through the valve cavity, the scouring abrasion from which the valve seats suffer can be decreased; and therefore, the situation of inner leakage occurring to the valve is effectively prevented.
Description
Technical field
The present invention relates to a kind of ultrahigh pressure mitre velve, particularly a kind of super-high pressure conical valve specific for coal slurry.
Background technique
Super-high pressure conical valve specific for coal slurry is the metal hard seal valve with tapered channel.Super-high pressure conical valve specific for coal slurry is generally used in the special valve of the pasty material transmission of the industries such as chemical industry, is mainly used in the valve switch that coal tar oil installs pipes.Its main structure is installed by valve body, valve seat, spheroid, valve rod and sealing system and trim and is formed, valve body is divided into left valve barrel and right valve barrel, simultaneously, left and right sides valve seat is made respectively large small-borely contact with spheroid, the proportional flow of assistant sphere control channel inner fluid in the valve opening and closing process, simultaneously, also play the effect of sealing.Spheroid by original put-through channel should be the passage with certain taper, do not change 1: 3 into by original 1: 1 flow cross during standard-sized sheet at valve body.At present, domestic metal hard-sealing ball valve Main Problems is: valve is using a period of time valve seat can be subject to certain wearing and tearing, and it is more that particularly right valve seat is subject to washing away of medium.Cause the pretension sealing force between ball core and the valve seat to reduce, the sealability during valve closing between the sealing pair reduces, and interior leakage may appear in valve when serious.
Summary of the invention
Technical problem to be solved by this invention provides a kind of super-high pressure conical valve specific for coal slurry, and it can reduce the erosive wear that valve seat is subject to, and has effectively prevented the situation of the interior leakage that valve occurs.
For solveing the technical problem, the invention provides a kind of super-high pressure conical valve specific for coal slurry, it is characterized in that, it comprises valve body, valve gap, support ring, left valve seat, spheroid, valve rod, right valve seat, stuffing box, gland, valve gap is fixed by at least one bolt and valve body, support ring is between left valve seat and valve gap, and spheroid is positioned at the valve pocket of valve body and valve gap formation, and left valve seat and right valve seat lay respectively at the both sides of spheroid; Valve rod is connected with spheroid is vertical, and stuffing box is positioned on the valve body, and gland is positioned at the top of stuffing box.
Positive progressive effect of the present invention is: the present invention changes the flow velocity of fluid and the effect of pressure by valve pocket, can reduce the erosive wear that valve seat is subject to, and has effectively prevented the situation of the interior leakage that valve occurs.
Description of drawings
Fig. 1 is the structural representation of super-high pressure conical valve specific for coal slurry of the present invention.
Embodiment
The below lifts a preferred embodiment, and comes by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
As shown in Figure 1, super-high pressure conical valve specific for coal slurry of the present invention comprises valve body 1, valve gap 2, support ring 3, left valve seat 4, spheroid 5, valve rod 6, right valve seat 7, stuffing box 8, gland 9, valve gap 2 is fixing by at least one bolt and valve body 1, support ring 3 is between left valve seat 4 and valve gap 2, spheroid 5 is positioned at the valve pocket of valve body 1 and valve gap 2 formation, and left valve seat 4 and right valve seat 7 lay respectively at the both sides of spheroid 5; Valve rod 6 and 5 vertical connections of spheroid, stuffing box 8 is positioned on the valve body 1, and gland 9 is positioned at the top of stuffing box 8.The stuffing box packing at valve handle activity position has teflon and graphite.The sealing surface of left valve seat 4, right valve seat 7 and spheroid 5 is built-up welding and spraying titanizing tungsten alloy respectively, and the raising valve is wear-resisting, decay resistance.The present invention changes the flow velocity of fluid and the effect of pressure by valve pocket, can reduce the erosive wear that valve seat is subject to, and has effectively prevented the situation of the interior leakage that valve occurs, long service life.Valve inner pressure can change, but the pressure of valve two passwaies is constant, can not affect its working pressure demand.According to the bernoulli principle, because stagnation pressure is certain, when fluid-flow rate reduces, its pressure also reduces.Flow velocity and overflow section are long-pending to be inversely proportional to, so we are not difficult to learn that flow section is long-pending large, flow velocity is just little, and its pressure also can diminish.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make various changes or modifications to these mode of executions.Therefore, protection scope of the present invention is limited by appended claims.
