Description
Technical field
The utility model relates to a kind of offshore oil underwater kit, is specifically related to a kind of high-pressure electric stop valve and the controlling method thereof with spool stress balance.
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 good seal performance, the etch-proof high-pressure electric stop valve with spool stress balance, 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 high-pressure electric stop valve with spool stress balance, good seal performance, corrosion protection, and steering force is less, can telecontrol.
For achieving the above object, the utility model provides a kind of high-pressure electric stop valve with spool stress balance, comprise spring seat, balance base, spring, pad, valve body, sealing plate, needle, compressing tablet, adjustable lever, driven gear, motor, motor dividing plate, one zero RunddichtringO, 20 RunddichtringO, driving gear and transmission housing, spool is provided with in valve body, spool left end is matched with balance base by sealing plate, in balance base, spring seat is provided with spring, spring is matched with spool by pad, spool right-hand member is connected with needle, needle passes through compressing tablet, one zero RunddichtringO matches with thread slider structure, thread slider structure is matched with valve body by the 20 RunddichtringO, needle is also connected with adjustable lever, valve body right-hand member and transmission housing are fixed, transmission housing inside is provided with the driven gear engaged with driving gear, driving gear is connected with motor, driven gear and be provided with motor dividing plate between driving gear and motor.
Preferably, described valve inner is provided with balanced runner hole.
Utilize a controlling method for above-mentioned high-pressure electric stop valve, its method is as follows:
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, enters C chamber, acts 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, direction is contrary, is a pair equilibrant, and first, second zero shape circle frictional force offset by spring;
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, and first, second zero shape circle frictional force offset by spring.
The beneficial effects of the utility model: the spool two ends stress balance of this high-pressure electric stop valve, valve body structure is simple, good seal performance, and steering force is less, can telecontrol.
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 high-pressure electric stop valve with spool stress balance, 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, driven gear 10, motor 11, motor dividing plate 12, one zero RunddichtringO 13, 20 RunddichtringO 14, driving gear 15 and transmission housing 16, spool is provided with in valve body 5, spool left end is matched with balance base 2 by sealing plate 6, in balance base 2, spring seat 1 is provided with spring 3, spring 3 is matched with spool by pad 4, spool right-hand member is connected with needle 7, needle 7 is by compressing tablet 8, one zero RunddichtringO 13 matches with thread slider structure, thread slider structure is matched with valve body by the 20 RunddichtringO 14.
In the present embodiment, needle 7 is also connected with adjustable lever 9, valve body 5 right-hand member and transmission housing 16 are fixed, transmission housing 16 inside is provided with the driven gear 10 engaged with driving gear 15, driving gear 15 is connected with motor 11, driven gear 10 and be provided with motor dividing plate 12 between driving gear 15 and motor 11.
It should be noted that 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 plays a part to offset zero shape circle frictional force.When valve body opened by needs, only need the very little moment of torsion of motor just can open valve body.
