The connection of 4th oil-through-hole 104.
Further, valve body includes valve seat 110 and valve pocket 120, and valve pocket 120 is embedded in valve seat 110, and accommodating chamber is set to valve
Set 120;
Valve seat 110 is equipped with seven valve seat oil-through-holes, and valve pocket 120 is equipped with seven valve pocket oil-through-holes, seven valve seat oil-through-holes with
Seven oil-through-holes are connected to correspondingly.
Specifically, valve seat 110 is in cuboid, the ring-shaped section and ring-shaped of valve pocket 120, valve pocket 120 is embedded at valve seat 110
Inside, and length direction is identical as the length direction of valve seat 110.Sealing element 300 be located at one end of valve seat 110 and with valve seat 110
It is fixedly connected, to be sealed to the accommodating chamber on valve pocket 120.Length of the axis of seven valve seat oil-through-holes with valve seat 110
Direction is vertical, and the axis of seven valve pocket oil-through-holes is vertical with the axis of 120 axis of valve pocket, seven valve seat oil-through-holes and seven valve pockets
Oil-through-hole is connected to correspondingly, so that accommodating chamber is connected to outside.One end of valve rod 200 is located in valve pocket 120, and the other end is worn
It crosses sealing element 300 to be located at outside valve pocket 120, inner wall of the periphery wall of each axis rank with valve pocket 120 is slidably matched.Valve pocket 120 with
Cancel oil sealing isolation between each axis rank, the shortcomings that avoiding rubber seal rapid wear, it is larger to reach pressure-bearing, with valve rod 200 it
Between wearability it is good, to keep three seven port valves provided in an embodiment of the present invention durable.
Further, valve pocket 120 is made of HT800.
Many corrosive medium corrosion can be resistant to using valve pocket 120 made of HT800.Its higher nickel content makes it aqueous
Etching condition has good stress-corrosion-cracking resistance.High chrome contents are with better resistance to spot corrosion and crevice corrosion
Cracking performance.The alloy has good resistance to nitric acid, organic acid corrosivity, but the corrosion resistance in sulfuric acid and hydrochloric acid has
Limit.In addition to being had good corrosion resistance in oxidisability and non-oxidizable salt other than halide is likely to occur spot corrosion.?
Water, steam and steam, air, carbon dioxide mixture in also tool have good corrosion resistance.
Further, valve body is equipped with the mounting hole for installing valve pocket 120, and valve pocket 120 and mounting hole are interference fitted.
Specifically, mounting hole extends along the length direction of valve seat 110, and run through one end of valve seat 110, the logical oil of seven valve seats
The side wall of the equal penetrating mounting holes in hole.The outer diameter of valve pocket 120 is slightly larger than the internal diameter of mounting hole, and valve pocket 120 and mounting hole use interference
The mode of cooperation connects, and improves the stability that valve pocket 120 is connect with valve seat 110.
Further, sealing element 300 includes sealing framework 310 and first end cover 320, and sealing framework 310 is installed on first
The side opposite with valve body of end cap 320, first end cover 320 are installed on the first end of accommodating chamber, and valve rod 200 passes through sealing framework
310 and first end cover 320.
Specifically, first end cover 320 includes interconnecting piece and sealing, the peripheral dimension of sealing is greater than the periphery of limiting section
Size.When first end cover 320 is installed on valve seat 110, the periphery wall of limiting section is contacted with the inner wall of mounting hole, passes through clamping
Mode and the inner wall of mounting hole connect, limiting section prevents first end cover 320 from moving radially relative to valve seat 110.Sealing
Peripheral dimension is greater than the diameter of mounting hole, cooperates with limiting section and is sealed the end of mounting hole.
Sealing framework 310 is located in mounting hole, and is installed on the medial surface of limiting section.First end cover 320 is equipped with cooperation
Through-hole cooperates the axis of through-hole to be overlapped with the axis of accommodating chamber.Valve rod 200 passes through sealing framework 310 and cooperation through-hole, seals bone
The inner wall of frame 310 and the inner wall of cooperation through-hole are contacted with the periphery wall of valve rod 200.Sealing framework 310 carries out accommodating chamber close
Envelope prevents the hydraulic oil in accommodating chamber from passing through cooperation through-hole exudation.
Further, sealing framework 310 is made of elastic material.
Specifically, sealing framework 310 can have rubber or silica gel material to be made.Valve rod 200 is relative to valve pocket 120 and first end
Lid 320 slides, and when the axis of valve rod 200 is not overlapped with the axis of the axis of accommodating chamber or matching hole, sealing framework 310 is generated
Flexible deformation appropriate, from make valve rod 200 can in its radial motion, adjust valve rod 200 axis and holding tank axis and match
The registration for closing the axis of through-hole, prevents valve rod 200 to be stuck.The sealing framework 310 made of elastic material is reducing respectively
While a element coaxial degree requires, the flatness that valve rod 200 moves ensure that.
Further, the end face opposite with valve body of end cap is equipped with mounting groove, and sealing framework 310 is installed in mounting groove.
Specifically, the section of mounting groove is rounded, and when sealing framework 310 is installed in holding tank, the inner circumferential of mounting groove
Wall is contacted with the periphery wall of sealing framework 310, and sealing framework 310 is fixed and is limited.
Further, the second end of accommodating chamber is fixedly installed with second end cover 330, and second end cover 330 is for sealing installation
Hole and accommodating chamber.
Specifically, mounting hole is through-hole, facilitate the installation of valve pocket 120, the installation of second end cover 330 is pacified by way of clamping
Second end loaded on valve seat 110, is sealed mounting hole and accommodating chamber.
Further, valve rod 200 is made of 20CrMoTi.
20CrMnTi is carburizing steel, and carburizing steel is usually the mild steel that phosphorus content is 0.17%-0.24%.It is more on automobile
Transmission gear is manufactured with it, is CrMnTi steel in middle harden ability carburizing steel, harden ability is higher, special when guaranteeing through hardening
It is not low-temperature impact toughness with higher.20CrMnTi hardened case processing steel, has good processability, processing
Deform small, anti-fatigue performance is fairly good.The process of valve rod 200 forges, is quenched, surface hardening refines.Surface segmentation is at five
A axis rank.This way principle is simple, is easy to implement, and better performances.
