Description
Technical field
The invention belongs to Machine Design and ceramic new material and its Application of composite fields, are related to a kind of oil drilling high pressure
Slurry pump ceramic cage valve.
Background technique
Ceramic cage valve is a kind of core component of high pressure slurry pump for deep-well petroleum exploitation, applied to slush pump
Fluid end gets sucking and the effect that mud is discharged；Due to the grinding of shape hard sand particles contained in drilling mud, slurry liquid
It washes away and is corroded by acidic materials in oil well, cause the damage of valve body land,
In addition, valve ontology sealing surface is easily bad by thorn under high temperature and pressure and the higher working condition of silt content, cause
Mud leakage, insufficient pressure cause slush pump to break down.Frequently replacement valve, downtime is long, cause a large amount of material at
The waste of this and cost of labor.
Current common ball valve, although its fluid resistance is small, the ball valve of full-bore is substantially without flow resistance.But in its opening and closing
When, certain resistance can be generated, in the case where especially having impurity, is very easy to be blocked by impurity, causes valve that can not open.
Therefore the structure design of optimization valve body and raising the wear-resistant of valve body land, resistance to erosion, corrosion-resistant and high temperature resistant
Performance is to improve the fundamental way of its service life.
Summary of the invention
The present invention provides a kind of oil drilling high pressure slurry pump ceramic cage valves.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of high pressure slurry pump ceramic cage valve, including valve seat and valve deck, install ceramics between the valve seat and valve deck
Ball is provided with multiple fluid windows on the valve deck, and a valve deck polyurethane cushion is equipped between Ceramic Balls and valve deck, is being made pottery
It is equipped with a valve seat polyurethane cushion between porcelain ball and valve seat, one is added between the valve seat polyurethane cushion and Ceramic Balls
Washer.
The valve seat, valve deck and washer are all made of 20Cr2Ni4A steel alloy, and forging temperature is 920-950 DEG C.
The processing of the valve seat, valve deck and washer, through+780 DEG C of oil quenchings of 880 DEG C of oil quenchings after carburizing, then at 200 DEG C of tempering
Reason reaches the hardness 434HB, tensile strength 1483MPa of requirement.
The Ceramic Balls material is zirconium oxide or Zirconia reinforced alumina or silicon nitride material.
The ceramic ball processing, cold isostatic compaction, briquetting pressure 250-300MPa, sintering temperature be 1500 DEG C-
1650 DEG C, 2-5h, polishing treatment Ceramic Balls are kept the temperature, spherical surface roughness Ra is 0.02-0.05um.
Beneficial effects of the present invention are：
1. cage gauge valve integrated designs, simple for structure, smoothness is run between each component, considerably increases service life, it is special
It is not applied to the mud suction under high temperature, high pressure and the strong working condition of impact force.
2. substituting metal ball, wear-resistant, the high-temperature stability of Ceramic Balls, in high temperature and pressure and silt content using Ceramic Balls
Durability is significantly stronger than traditional ball valve and valve under the conditions of higher.
3. Ceramic Balls will not generate electrochemical corrosion, while have better corrosion resistance, even if under containing acid or alkali environment
Using will not corrode.
4. the low thermal expansion of spheres of ceramic adds surplus structure to design, so that also there is no engagements in use for cage valve
Face is because of a possibility that generating cracking and destroying of expanding with heat and contract with cold.

Specific embodiment
Present invention is further described in detail in the following with reference to the drawings and specific embodiments.
A kind of high pressure slurry pump ceramic cage valve, including valve seat 1 and valve deck 2, are installed between the valve seat 1 and valve deck 2
Ceramic Balls 3 are provided with multiple fluid windows 6 on the valve deck 2, and a valve deck polyurethane is equipped between Ceramic Balls 3 and valve deck 2
Bed course 5 is equipped with a valve seat polyurethane cushion 4, in the valve seat polyurethane cushion 4 and ceramics between Ceramic Balls 3 and valve seat 1
A washer 7 is added between ball 3.
The principle of the invention is, when fluid passes through cage valve, Ceramic Balls 3 leave ball seat, and circulation passage is opened, and fluid can be with
Pass through, when reverse fluid flow, Ceramic Balls 3 are sitting on cage valve seat 1 under the action of pressure (or other power), and circulation is logical
Road is closed, and fluid (mud) is sucked or is discharged from fluid window 6；
The processing of valve seat, valve deck and washer：Valve seat, valve deck and washer use 20Cr2Ni4A steel alloy, through high temperature forging
