Description
Technical field
The utility model relates to a kind of stop valve, is specifically related to a kind of sealing corrosion high pressure hand-operated stop valve for high water base fluid pressure.
Background technique
Along with rising violently of International Petroleum Price, the price of oil based fluids also promotes thereupon, and re-using oil based fluids just increases cost of production and maintenance expenses virtually.Therefore seek cheap high performance oil based fluids to be brought into schedule.
In recent decades, the development of high water base fluid hydraulic fluid receives very large attention, but 2 is need key problems-solving at present below: 1. high water base contain about 95% water, easily leak, sealing had higher requirement; 2. high water base fluid hydraulic fluid easily corrodes spool, and we will consider the substitution material of traditional spool, prevents the high water base corrosion to spool.
Therefore, be necessary to design a kind of sealing corrosion high pressure hand-operated stop valve for high water base fluid pressure, to overcome the problems referred to above.
Model utility content
Because the above-mentioned defect of prior art, the utility model provides a kind of sealing corrosion high pressure hand-operated stop valve for high water base fluid pressure, spool two ends stress balance, and valve body structure is simple, and good seal performance, steering force is less.
For achieving the above object, the utility model provides a kind of sealing corrosion high pressure hand-operated stop valve for high water base fluid pressure, comprise spring seat, balance base, spring, pad, valve body, sealing plate, needle, compressing tablet, adjustable lever, end seat, regulating handle and valve seat, above valve seat, the 3rd O RunddichtringO and the 4th O RunddichtringO are provided with valve body, spool is provided with in valve body, spool is matched with balance base by sealing plate, in balance base, spring seat is provided with spring, spring right-hand member is matched with spool left end by pad, spool right-hand member is connected with needle, needle passes through compressing tablet, one O RunddichtringO matches with end seat, end seat is also matched with valve body by the 2nd O RunddichtringO, adjustable lever left end is connected with needle, and adjustable lever is located in end seat, adjustable lever right-hand member is connected with regulating handle.
As preferably, described end seat is connected with valve body screw thread.
As preferably, described regulating handle is thread slider formula operating grip.
As preferably, described valve inner is provided with balanced runner hole.
The beneficial effects of the utility model: spool two ends stress balance, valve body structure is simple, and good seal performance, steering force is less.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, this embodiment is by the following technical solutions: a kind of sealing corrosion high pressure hand-operated stop valve for high water base fluid pressure, comprise spring seat 1, balance base 2, spring 3, pad 4, valve body 5, sealing plate 6, needle 7, compressing tablet 8, adjustable lever 9, end seat 10, regulating handle 11 and valve seat 12, above valve seat 12, the 3rd O RunddichtringO 15 and the 4th O RunddichtringO 16 are provided with valve body 5, spool is provided with in valve body 5, spool is matched with balance base 2 by sealing plate 6, in balance base 2, spring seat 1 is provided with spring 3, spring 3 right-hand member is matched with spool left end by pad 4, spool right-hand member is connected with needle 7, needle 7 is by compressing tablet 8, one O RunddichtringO 13 matches with end seat 10, end seat 10 is also matched with valve body 5 by the 2nd O RunddichtringO 14, adjustable lever 9 left end is connected with needle 7, and adjustable lever 9 is located in end seat 10, adjustable lever 9 right-hand member is connected with regulating handle 11.
It should be noted that described end seat 10 is threaded with valve body 5.
It should be noted that described regulating handle 11 is thread slider formula operating grip.
In addition, described valve body 5 inside is provided with balanced runner hole.
The working principle of this embodiment: when stop valve closed condition, A chamber enters high-voltage oil liquid, act on spool right side, hydrodynamic force, direction left, is closed spool; Fluid is through balance liquid flow channel for oil hole simultaneously, and enter C chamber, act on valve core piston left side, hydrodynamic force, direction, acts on the hydraulic coupling equal and opposite in direction on needle to the right with A chamber, and direction is contrary, is a pair equilibrant.Spring 3 works to offset O shape circle mill and examines power.When valve body opened by needs, only need operate the very little moment of torsion of regulating handle 11 just can open valve body.
When stop valve open mode, A, B chamber enters high-voltage oil liquid, and act on valve core piston right side, hydrodynamic force, direction left; Fluid is through balance liquid flow channel for oil hole simultaneously, and enter C chamber, act on valve core piston left side, hydrodynamic force, direction, acts on the hydraulic coupling equal and opposite in direction on needle to the right with B chamber, and direction is contrary, is a pair equilibrant.Spring 3 works to offset O shape circle mill and examines power.When needs valve body, only need operate the very little moment of torsion of regulating handle 11 just can valve body.
When stop valve closed condition, B chamber enters high-voltage oil liquid, acts on spool left side, hydrodynamic force, and, there is spool in direction the trend opened to the right; Fluid acts on valve core piston right side simultaneously, hydrodynamic force, and left, with the hydraulic coupling equal and opposite in direction acted on needle, direction is contrary, is a pair equilibrant in direction.Spring 3 works to offset O shape circle mill and examines power.When valve body opened by needs, only need operate the very little moment of torsion of regulating handle 11 just can open valve body.
This embodiment comprises the spool with Equilibrator, the spring being arranged on spool left end, is arranged on the balanced runner hole of valve inner and is arranged on the operating grip of spool right-hand member.The spool two ends stress balance of this high pressure hand-operated stop valve, valve body structure is simple, and good seal performance, steering force is less.
