Abstract
The utility model discloses a novel sealing structure of slurry pump hydraulic suction side. The novel sealing structure comprises a valve (7), a valve seat (8), a pump head body (9), a water inlet pipe (10), first sealing rings (11) and a second sealing ring (12), wherein the valve (7) is mounted in the valve seat (8) in a sealing manner; the valve seat (8) is mounted in the pump head body (9) in a sealing manner through the two first sealing rings (11) arranged in a first sealing ring groove; the lower end of the valve seat (8) stretches out of the pump head body (9) to form a radial flange (8-2); a second sealing ring groove (8-2-1) is formed in the radial flange (8-2); and the inner surface (9-1) of the pump head body (9) is designed to be a straight cylindrical surface; the water inlet pipe (10) is fixedly mounted on the pump head body (9) and in touch with the radial flange (8-2), so as to form sealing with the radial flange (8-2) through the second sealing ring (12). According to the utility model, the accuracy requirement to the outer surface of the valve body and the inner surface of the pump head body is lowered to some extent, so that the production cost and the processing difficulty can be greatly reduced.
Description
Technical field
The utility model relates to geological drilling field, particularly a kind of slurry pump fluid power suction side novel sealing structure.
Background technique
In geological drilling industry, the piston high-density pump equipment that is absolutely necessary.Its effect is to suck after liquid, with certain pressure and flow, discharges again.
The structure of existing slurry pump fluid power suction side sealing configuration as shown in Figure 1, it comprises valve 1, pump head body 2, valve seat 3 and intake pipe 4, valve seat 3 is arranged in pump head body 2, intake pipe 4 is mounted by means of bolts on pump head body 2, the male cone (strobilus masculinus) 3-1 of described valve seat 3 matches (as shown in Figure 2,3) with the inner conical surface 2-1 of pump head body 2, form self-locking to reach sealing, valve 1 is arranged in valve seat 3 endoporus, by pump head body 2 interior separations, is active chamber 5 and water-inlet cavity 6.Its working principle is: when needs are intake, valve 1 moves upward, and now active chamber 5 is communicated with water-inlet cavity 6; When needs stop into water, valve 1 moves downward, and fits tightly with valve seat 3, and now active chamber 5 is not communicated with mutually with water-inlet cavity 6.
In order to guarantee the sealing of this structure, the inner conical surface required precision of the male cone (strobilus masculinus) of valve seat 3 and pump head body 2 is high, but pump head body 2 volumes are large and out-of-shape, add special cutter for man-hour requirement, and difficult processing is to guarantee precision on machine tool, so manufacture difficulty is large, processing cost is high, and manufacturing efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of technology capability good, and cost of production is low, the slurry pump fluid power suction side novel sealing structure that manufacturing efficiency is high.
The technical solution of the utility model is: a kind of slurry pump fluid power suction side novel sealing structure, comprises valve, valve seat, pump head body, intake pipe and seal ring; Described valve is arranged in valve seat endoporus, by pump head body interior separation, is active chamber and water-inlet cavity; Described valve seat outer surface is provided with seal groove, and is arranged in pump head body by the seal ring sealing being located in seal groove; Described intake pipe is fixedly mounted on pump head body.
The further technological scheme of the utility model is: the outer surface of valve seat and the with it internal surface of the pump head body of cooperation are straight cylindrical surfaces.
The utility model further technological scheme is: described valve seat is cylindrical, and its outer surface is provided with two the first seal grooves, and is arranged in pump head body by two the first seal ring sealings that are located in the first seal groove.
The utility model further technological scheme is: valve seat lower end is stretched out pump head body and formed radial flange, radial flange is provided with the second seal ring slotted vane, intake pipe contacts with the radial flange of valve seat lower end, by being located at, forms sealing between the second seal ring in the second seal groove and radial flange.
The utility model adopts as above design, compared with prior art has following features:
1, at valve seat outer surface, be processed with seal groove, by the seal ring being arranged in seal groove, realize the sealing between pump head body and valve seat, thereby the required precision to valve outer surface and pump head body internal surface decreases, and has significantly reduced cost of production and difficulty of processing.
2, valve outer surface and pump head body internal surface are all designed to straight cylindrical surfaces, are convenient to process on common extra bed, without design specialized cutter, have further reduced cost of production, have promoted manufacturing efficiency.
Below in conjunction with figure and embodiment, detailed structure of the present utility model is further described.
