Abstract
The utility model provides a plunger pump valve box valve seat cone hole structure. A valve seat cone hole is formed by a cone hole with conicity of 1:16. The plunger pump valve box valve seat cone hole structure overcomes the defects of the prior art, is simple and reasonable in structure, safe, and reliable, does not need a valve body guide seat, can be assembled with a universal valve seat, brings convenience to the detachment of a valve seat, effectively improves the efficiency of replacing the valve seat which is a quick-wear part, and saves the time for replacing the valve seat.
Description
Technical field
The utility model relates to a kind of plunger pump clack box valve seat taper hole structure, belongs to fracturing work device technique field.
Background technique
At present, after traditional plunger pump clack box valve seat taper hole structure and assembling thereof, structure respectively as depicted in figs. 1 and 2, the valve seat taper hole 1 of traditional plunger pump clack box discharge side, the valve seat taper hole 2 of suction chamber are the tapering week faces that valve seat 4 taperings with the hydraulic end of plunger pump assembly match, valve seat 4 is assemblied on the valve seat taper hole, and firmly seals drive fit with it.The tapering of traditional valve seat taper hole is 1: 8, and the tapered hole below is provided with straight step hole, and purpose is for valve body guide holder 5 is installed, and plays the effect that righting and guiding valve body repeat opening and closing up and down.Traditional valve seat taper hole can not assemble with general valve seat, and the valve seat 4 of assembling with it needs special.
Because valve seat 4 is easily damaged partss, therefore need frequent dismounting and change.Valve seat 4 belows are provided with valve body guide holder 5, open and close the impact of impact force at the valve body assembly 3 that is subject to the alternation high pressure fluid, and under the long-term effect in high pressure, high aggressive medium, valve seat 4 conical surfaces are pressed tighter and tighter, the easy rust corrosion of the conical surface, be stained with extremely on suction chamber tapering week face, even adopt special-purpose valve seat drawbench extracting tool, want to complete quickly and easily the valve seat dismounting and change also very difficult.
In practical operation, often because of the anti-step part that hooks under two ringfeders of extracting tool, fail to fit like a glove, the impact that valve seat 4 belows have again valve body guide holder 5 to interfere, the while inconvenient operation, the drawbench extracting tool does not make power, and the drawbench ringfeder very easily damages, and valve seat is difficult to pull out, normally get half the result with twice the effort, lose time very much.Therefore, the valve seat taper hole structure of plunger pump clack box reasonable in design, improve the efficiency of changing the easily damaged parts valve seat and seem extremely important.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of simple and reasonable, safe and reliable, does not need the valve body guide holder, and dismantles valve seat plunger pump clack box valve seat taper hole structure easily.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of plunger pump clack box valve seat taper hole structure, it is characterized in that: the tapered hole that described valve seat taper hole is 1: 16 by tapering forms.
A kind of plunger pump clack box valve seat taper hole structure that the utility model provides adopts the tapered hole that tapering is 1: 16, removes the straight step hole of traditional tapered hole below, can assemble with the general part valve seat, forms sealing cone and coordinates.
When needs are changed the easily damaged parts valve seat, exhaust end is dismantled successively lower discharge pressure cap, is discharged gland, spring, valve body assembly, the gland end is dismantled successively lower suction pressure cap, is sucked gland, spring bracket, spring, valve body assembly, adopt special-purpose drawbench extracting tool to make its ringfeder cylindrical wall be attached to the lower Transverse plane that valve seat and lower anti-hook step are close to valve seat fully fully, under the hydraulic jack effect, moment is fast extracted valve seat, effectively improve the efficiency of changing the easily damaged parts valve seat, saved the time of changing valve seat.
The device that the utility model provides has overcome the deficiencies in the prior art, simple and reasonable, safe and reliable, do not need the valve body guide holder, can assemble with general valve seat, and the dismounting valve seat is convenient, effectively improve the efficiency of changing the easily damaged parts valve seat, saved the time of changing valve seat.
The accompanying drawing explanation
Fig. 1 is traditional plunger pump valve case valve seat taper hole structural representation;
Fig. 2 is schematic diagram after traditional plunger pump valve case valve seat taper hole structure assembling;
A kind of plunger pump clack box valve seat taper hole structural representation that Fig. 3 provides for the utility model;
The rear schematic diagram of a kind of plunger pump clack box valve seat taper hole structure assembling that Fig. 4 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Fig. 3 and Fig. 4 are respectively a kind of plunger pump clack box valve seat taper hole structure and the rear structural representation of assembling thereof that the utility model provides, described a kind of plunger pump clack box valve seat taper hole structure adopts the tapered hole that tapering is 1: 16, remove the straight step hole of traditional tapered hole below, the valve seat taper hole 6 of discharge side, the valve seat taper hole 7 of suction chamber form sealing cone with general valve seat 9 and coordinate.
When needs are changed easily damaged parts valve seat 9, exhaust end is dismantled lower discharge pressure cap 10 successively, discharge gland 11, spring 12, the valve body assembly 8 coordinated with general valve seat, the gland end is dismantled lower suction pressure cap 13 successively, suck gland 14, spring bracket 15, spring 12, the valve body assembly 8 coordinated with general valve seat, adopt special-purpose drawbench extracting tool to make its ringfeder cylindrical wall be attached to the lower Transverse plane that valve seat 9 and lower anti-hook step are close to valve seat 9 fully fully, under the hydraulic jack effect, moment is fast extracted valve seat, effectively improved the efficiency of changing the easily damaged parts valve seat, saved the time of changing valve seat.
A kind of plunger pump clack box valve seat taper hole structure that the utility model provides has thoroughly solved the Difficulty problem of drawing valve seat, effectively improved the efficiency of changing the easily damaged parts valve seat, saved the time of changing valve seat, but do not affect its performance and working life, and greatly reduce labor intensity.
