Abstract
The invention discloses a balance cage type single-seat regulation valve which comprises a valve body and is characterized in that a valve cover is arranged on the valve body; a valve core component is arranged in the valve body; a valve cage is arranged between the valve core component and the valve body; a tooth-shaped gasket is arranged between the valve cage and the valve body; a stuffing gasket is arranged in a stuffing box; a stuffing spring is arranged at the upper part of the stuffing gasket; the upper part of the stuffing spring is provided with lower stuffing, middle stuffing and upper stuffing; a stuffing gland and a stuffing pressure plate are arranged on the upper side of the upper stuffing; and a travel indicator is arranged above the stuffing pressure plate. In practical use, the balance cage type single-seat valve disclosed by the invention meets the requirement of ANSIB16.104IV-level leakage in the working conditions of large specification, large flow and relatively great pressure difference, and good economic benefits and social benefits are obtained.
Description
Technical field
The present invention relates to a kind of balance type cage type single seat regulating valve, belong to mechanical field.
Background technique
For existing technology, according to user's actual process conditional request, that is: the big flow of medium needs the valve of big specification; But require to leak grade of accuracy high (ANSI B16.104 IV level), and want to bear bigger pressure reduction (△ P), three conditions realize it being very difficult on a deck valve door; The hard sealing strip balance type of RFL type two-seater cage type regulating valve; Can bear big pressure reduction, the factor of structure has determined leakage class can only reach ANSI B16.104 III level, though and big specification single-seat adjusting valve can reach ANSI B16.104 IV level and leaks; But because actuator stem force and other intensity, rigidity reason; And can not bear big pressure reduction (△ P), for this reason, must consider the modulating valve of design new structure.
Summary of the invention
The purpose of this invention is to provide a kind of modulating valve, to overcome the deficiency of existing technology.
To achieve these goals, the present invention adopts following technological scheme:
A kind of balance type cage type single seat regulating valve comprises valve body, it is characterized in that; Valve body is provided with valve gap, is provided with mangetic core assembly in the valve body, is provided with valve cage between mangetic core assembly and the valve body; Be provided with dentiform gasket between valve cage and the valve body, in stuffing box, be provided with Packing seat, be provided with packing spring between Packing seat and the following filler; The packing spring upside is provided with down filler, middle filler and last filler, is provided with Gland and hold-down grid on last filler top, and the hold-down grid top is provided with travel indicator.
Preferably, offer pressure compensation opening on the mangetic core assembly, its objective is to guarantee that under medium High Pressure Difference state, spool does not receive the influence of axial medium static pressure basically.
Preferably, the throttling window upper and lower part of valve cage is provided with two sealing lines, and increases a filled polytetrafluoroethylene seal ring and stainless steel insert in a distance, top of last potted line, its objective is the cut-out that guarantees to go up the sealing position, realizes IV level anti-leak.
The present invention in actual use; Pointedly specialized designs RFPLb type balance balance type cage type single seat regulating valve; Satisfy big specification, big flow, the modulating valve of big pressure reduction is realized the requirement that ANSI B16.104 IV level is leaked, and obtains good using effect; Receive user's favorable comment, obtained good economic benefit and social benefit.
