Abstract
The utility model discloses a regulating valve with a double sealing face valve seat, which comprises a valve body, a valve cap, a valve rod and a valve plug, and the double sealing face valve seat is sheathed on an inlet matched with the valve plug; a sealing face of the valve plug and a sealing face of the double sealing face valve seat are sealed in a matching manner; a ring-shaped pressing sleeve is sheathed on the inner side at the upper part of the valve body; a window is arranged on one side wall of the ring-shaped pressing sleeve; and the valve cap and the ring-shaped pressing sleeve are in press-fit together. The regulating valve can be matched with various pneumatic and electric execution mechanisms with high reliability, so that the problems that the conventional regulating valve is instable to control, short in service life and trouble to maintain are solved thoroughly, and the high reliability is really met.
Description
Technical field:
The utility model valve technology field is specifically related to a kind of modulating valve that has the double-sealing face valve seat.
Background technique:
At present, its valve seat of common modulating valve all adopts thin walled structures, regular screw threads screw in smart small-sized valve body, must use special anchor clamps loading, unloading, and poor rigidity is yielding, can't use for a long time substantially, can't dismantle after particularly long-term the use at all, must change complete machine, can't realize high reliability automatic control requirement, the contradiction desirable with modern automatic control highlights day by day.
The model utility content:
The utility model is problem such as long and troublesome maintenance at control instability, the working life of existing modulating valve, and a kind of modulating valve that is applicable to that the various requirement sealing is tight, regulate the high automatic control workplace of reliability is provided.
Technological scheme: a kind of modulating valve that has the double-sealing face valve seat, comprise valve body, valve gap, valve rod and spool wherein, and are set with a double-sealing face valve seat in the import that spool cooperates, described valve core sealed cover and double-sealing face sealing surface of seat fitted seal, be set with an annular gland in the valve body upper inner, annular gland sidewall is provided with window, and described valve gap and annular gland press together.
Between described valve gap upper end and the valve rod annular chamber is set, be set with Packing seat in the annular chamber, be set with packing spring on the valve rod of Packing seat downside, annular chamber upside muzzle is equipped with filler presses nail, filler presses the upside suit of nail to be fixed with hold-down grid, is filled with filler in the annular chamber.
Beneficial effect: modulating valve of the present utility model has adopted high strength Olive Shape GLOBE valve body and high strength forging valve gap, top, adapted top guiding type valve core structure, and valve rod and spool adopt integrated design, have guaranteed the concrete highly reliable intensity of modulating valve.Valve seat adopts high strength not have worm structure, directly put into the valve body lumen, with band window gland fixed valve base, use the tight valve seat of defeating of valve gap double-screw bolt, strengthened the intensity of valve seat, improved the anti-leak grade of valve, valve seat adopts the double-sealing face design, after long-term use, occur leaking, only need the upset valve seat to reuse, improved the working life of modulating valve greatly, be not threaded because of valve seat adopt to have, so need not to adopt special anchor clamps loading, unloading, make the maintenance of modulating valve convenient, reliable.But gas, the electric actuator of the various high reliability of modulating valve adapted of the present utility model have thoroughly solved problems such as the long and troublesome maintenance of the control instability, working life of present modulating valve, and have really satisfied high reliability.
Description of drawings:
Fig. 1 is the cross-sectional view of the utility model modulating valve.
Number in the figure 1 is a valve body, and 2 is seal ring, and 3 is the double-sealing face valve seat, 4 is valve rod, and 5 is annular gland, and 6 are the valve bonnet seal circle, 7 is valve gap, and 8 is stud, and 9 is flat gasket, 10 is nut, and 11 is packing spring, and 12 is Packing seat, 13 is filler, 14 are filler pressure nail, and 15 is hold-down grid, and 16 is spool.
Embodiment:
Embodiment 1: referring to Fig. 1, a kind of modulating valve that has the double-sealing face valve seat comprises valve body 1, and valve body 1 top is fixed with high strength forging valve gap 7, and parts such as valve rod 4 and spool 16.Wherein, be set with a high-intensity double-sealing face valve seat 3 in the import (mounting hole) that cooperates with spool 16, adopt screwless to install.Described spool 16 sealing surfaces and double-sealing face valve seat 3 sealing surface fitted seal.Be set with an annular gland 5 in valve body 1 upper inner, annular gland 5 sidewalls are provided with window, and described valve gap 7 presses together with annular gland 5.In addition, between valve gap 7 upper ends and valve rod 4, annular chamber is set, be set with Packing seat 12 in the annular chamber, be set with packing spring 11 on the valve rod 4 of Packing seat 12 downsides, annular chamber upside muzzle is equipped with filler presses nail 14, filler presses the upside suit of nail 14 to be fixed with hold-down grid 15, is filled with filler 13 in the annular chamber.Stretch out outside the valve gap by the guide sleeve of valve body and valve gap joint the upper end of valve rod 4, be connected on the actuator shaft, and upper and lower moving with the driving of actuator, thereby driving the upper and lower of spool moves, with the orifice size size between change spool and the double-sealing face valve seat, thereby regulate the rate-of flow that flows out through valve.
When the inlet inflow valve inner of flowing medium through valve body 1, with moving on spool 16 parts, flowing medium is by the epicoele of the restriction inflow valve body at valve seat place, by the outlet incoming fluid pipeline of valve body.
Claims (2)
1. the modulating valve that has the double-sealing face valve seat, comprise valve body, valve gap, valve rod and spool, it is characterized in that: be set with a double-sealing face valve seat in the import that spool cooperates, described valve core sealed cover and double-sealing face sealing surface of seat fitted seal are set with an annular gland in the valve body upper inner, annular gland sidewall is provided with window, and described valve gap and annular gland press together.
2. the modulating valve that has the double-sealing face valve seat according to claim 1, it is characterized in that: between described valve gap upper end and the valve rod annular chamber is set, be set with Packing seat in the annular chamber, be set with packing spring on the valve rod of Packing seat downside, annular chamber upside muzzle is equipped with filler presses nail, filler presses the upside suit of nail to be fixed with hold-down grid, is filled with filler in the annular chamber.
