Abstract
The invention discloses a fluid pressure balancer which comprises a main body; a transverse channel is arranged inside the main body; a feed port communicated with the transverse channel is arranged at the side part of the main body; a discharge port is arranged at the front end of the transverse channel; and a pressure balancing device is arranged at the rear end of the transverse channel. The fluid pressure balancer is reasonable in design, simple in structure, small in size and high in automation degree. The fluid pressure balancer is used to match with a system in the fluid and polymer melt processing industry to ensure the continuity and stability of the operation of the system. The fluid pressure balancer puts an end to the faults and wastes caused by pressure fluctuation of a fluid material in the system, and therefore the fluid pressure balancer improves the economic benefit of an enterprise.
Description
Technical field
The present invention relates to a kind of fluid pressure balancer for fluid and polymer melt processing industry.
Background technology
The system used in fluid and polymer melt processing industry, in operation process, can cause the fluctuation of hydrodynamic pressure often because of fault, the fluctuation of pressure will cause filtration operation interrupt and make operational failure and product rejection.
Summary of the invention
The present invention, in order to solve weak point of the prior art, provides a kind of and avoids fluid pressure fluctuations and cause the fluid pressure balancer of operation inefficacy and product rejection.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: fluid pressure balancer, comprises body, interconnection is provided with in body, body side is provided with the charging aperture be communicated with interconnection, and the front end of interconnection is discharging opening, and the rear end of interconnection is provided with pressure equaliser.
Described body comprises the large cylinder with interconnection, and large cylinder right-hand member is provided with right flange, and discharging opening is located in the middle part of right flange.
Described pressure equaliser comprises the little cylindrical shell with cylindrical cavity, be slidably connected at the plunger in little cylindrical shell, be located at the pointer of plunger left end, displacement transducer and hydraulic jack, large cylinder left end is provided with annular boss, little cylindrical shell right-hand member extend into large cylinder left end and passes through sealing shroud, flowing channel sleeve and the press fit of annular boss top, the inner ring of sealing shroud and flowing channel sleeve and the cylindrical of plunger are closely slidably matched, flange during large cylinder left end is provided with and is threaded with little cylindrical shell cylindrical, little cylindrical shell upper lateral part offers elongated hole vertically, little cylindrical shell is stretched out by elongated hole in pointer upper end, displacement transducer is located at little cylindrical shell left upper part and is connected with pointer upper end, hydraulic jack is fixedly connected with little cylindrical shell by the left flange being located at little cylindrical shell left end, the piston rod of hydraulic jack extend in the cylindrical cavity of little cylindrical shell through left flange and is connected with plunger left end.
Adopt technique scheme, charging aperture and discharging opening respectively with the channel connection of fluid production system, when operation normally runs, in interconnection, be full of fluid foods, when the working pressure of pressure equaliser and system balances, plunger right-hand member is in the middle part transfixion of interconnection.
When accommodating fluid pressure drop in system, the piston rod of hydraulic jack promotes plunger left end and moves right, and interconnection inner fluid material is added in system and makes pressure reach balance.The pointer of plunger left end drives displacement transducer to move right simultaneously, and displacement transducer can output signal and add Iarge-scale system feed quantity, and in system, pressure gos up to make plunger to return equilibrium position.Otherwise when in system, fluid foods is more, the piston rod that plunger will promote hydraulic jack is moved to the left, fluid unnecessary in system is cached in interconnection, still keeping system fluid pressure is constant, pointer drives displacement transducer to be also moved to the left, displacement transducer output signal minimizing system feed quantity, in system, pressure reduction makes plunger return equilibrium position.The pressure stability of fluid foods in system can be remained like this.
The present invention is reasonable in design, structure is simple, volume is little, automaticity is high, support the use in the system of fluid and polymer melt processing industry, thus guarantee the stability of system job, stop the fault that causes because of the pressure surge of fluid foods in system and waste product, improve the economic benefit of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, fluid pressure balancer of the present invention, comprises body, is provided with interconnection 1 in body, and body side is provided with the charging aperture 2 be communicated with interconnection 1, and the front end of interconnection 1 is discharging opening 3, and the rear end of interconnection 1 is provided with pressure equaliser.Body comprises the large cylinder 4 with interconnection 1, and large cylinder 4 right-hand member is provided with right flange 5, and discharging opening 3 is located in the middle part of right flange 5.
Pressure equaliser comprises the little cylindrical shell 7 with cylindrical cavity 6, be slidably connected at the plunger 8 in little cylindrical shell 7, be located at the pointer 9 of plunger 8 left end, displacement transducer 10 and hydraulic jack 11, large cylinder 4 left end is provided with annular boss, little cylindrical shell 7 right-hand member extend into large cylinder 4 left end and by sealing shroud 12, flowing channel sleeve 13 and the press fit of annular boss top, the inner ring of sealing shroud 12 and flowing channel sleeve 13 and the cylindrical of plunger 8 are closely slidably matched, flange 14 during large cylinder 4 left end is provided with and is threaded with little cylindrical shell 7 cylindrical, little cylindrical shell 7 upper lateral part offers elongated hole 15 vertically, little cylindrical shell 7 is stretched out by elongated hole 15 in pointer 9 upper end, displacement transducer 10 is located at little cylindrical shell 7 left upper part and is connected with pointer 9 upper end, hydraulic jack 11 is fixedly connected with little cylindrical shell 7 by the left flange 16 being located at little cylindrical shell 7 left end, be connected with plunger 8 left end in the piston rod 17 of hydraulic jack 11 extend into little cylindrical shell 7 cylindrical cavity 6 through left flange 16.
When work uses, charging aperture 2 and discharging opening 3 respectively with the channel connection of fluid production system, when operation normally runs, fluid foods is full of in interconnection 1, when pressure equaliser (pressure in hydraulic jack 11) balances with the working pressure of system, plunger 8 right-hand member tip transfixion in the middle part of interconnection.
When accommodating fluid pressure drop in system, the piston rod 17 of hydraulic jack 11 promotes plunger 8 left end and moves right, and interconnection 1 inner fluid material is added in system and makes pressure reach balance.The pointer 9 of plunger 8 left end drives displacement transducer 10 to move right simultaneously, and displacement transducer 10 can output signal and add Iarge-scale system feed quantity, and in system, pressure gos up to make plunger 8 return equilibrium position.Otherwise when in system, fluid foods is more, the piston rod 7 that plunger 8 will promote hydraulic jack 11 is moved to the left, fluid unnecessary in system is cached in interconnection 1, still keeping system fluid pressure is constant, pointer 9 drives displacement transducer 10 to be also moved to the left, displacement transducer 10 outputs signal minimizing system feed quantity, and in system, pressure reduction makes plunger 8 return equilibrium position.The pressure stability of fluid foods in system can be remained like this.
