Abstract
The invention belongs to the technical field of manufacture of a sealing device of a high-pressure pump, and particularly relates to a high-pressure pump valve seat. The high-pressure pump valve seat is characterized by comprising a valve seat body, wherein two hard material layers are embedded around the inner side and the outer side of a liquid inlet channel; and a hard material layer is embedded around the liquid outlet channel of the valve seat. The high-pressure pump valve seat has the advantages that the structure is simple; and since the ultra-hard materials are embedded around the water inlet channel and the water outlet channel of the valve seat, the condition that the position is washed away by water flow is avoided and the service life of the valve seat is prolonged.
Description
Technical field
The invention belongs to the seal arrangement manufacturing technology field of high-pressure service pump, relate in particular to a kind of high-pressure service pump valve seat.
Background technique
The domestic and international pump produced of plunger pump manufacturer, feed liquor valve and the liquid discharging valve of employing all are that do not have power passive driven entire valve substantially.Begin when plunger stretches out working stroke, the thrust of plunger makes liquid produce pressure, and liquid discharging valve is opened, and the feed liquor valve closes entire under the effect of spring force simultaneously; Plunger continues to move ahead and Ans Chord curve speedup and deceleration, and liquid discharging valve is opened manyly because flow velocity increases under the impact of working fluid, and flow velocity reduces and opens gradually little opening of valves, and liquid discharging valve closes entire under the effect of spring force simultaneously; Plunger continues retraction, and the feed liquor valve begins withdrawal after liquid fluidization tower plug reaches farthest, and the feed liquor stroke begins, and it is gradually big that the fluid pressure in the feed pathway is opened feed liquor under impacting---and gradually little.At present, (sharp side that flap impacts) because water velocity is very big, the long-time impact causes being polished herein in the feed pathway of valve seat and the position of liquid outlet channel, causes valve seat to lose efficacy.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of high-pressure service pump valve seat is provided, improve the working life of valve seat.
The present invention for achieving the above object, by the following technical solutions: a kind of high-pressure service pump valve seat, it is characterized in that: comprise the valve seat body, the feed pathway of described valve seat inside and outside two side ring weeks be inlaid with two hard material layers, the liquid outlet channel ring week of described valve seat is inlaid with hard material layer.
Described hard material layer adopts superhard material.
Described superhard material is diamond or cubic boron nitride.
Beneficial effect: the present invention is simple in structure, owing to all be inlaid with superhard material, the situation of so just having avoided this place to be fallen by current scour, the working life of having improved valve seat at intake tunnel and the exhalant canal of valve seat.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1;
Among the figure: 1, valve seat body; 2, feed pathway; 3, hard material layer; 4, liquid outlet channel; 5, hard material layer.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1 to Figure 3, a kind of high-pressure service pump valve seat comprises valve seat body 1, the feed pathway 2 of described valve seat inside and outside two side ring weeks be inlaid with two hard material layers 3, the liquid outlet channel of described valve seat 4 rings are inlaid with hard material layer 5 week.Specifically, because intake tunnel is to be arranged on the valve seat in ring week, so hard material layer 3 is embedded in the both sides of the water intake of intake tunnel, and inlay hard material layer too at the water outlet place of exhalant canal.Owing to be provided with hard material layer in the ring week of liquid outlet channel, stand bigger current scour, make valve seat have long working life.
In the present invention, described hard material layer adopts superhard material.Described superhard material is diamond or cubic boron nitride.
The present invention is simple in structure, owing to all be inlaid with superhard material, the situation of so just having avoided this place to be fallen by current scour, the working life of having improved valve seat at intake tunnel and the exhalant canal of valve seat.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
