Specific embodiment

With reference now to accompanying drawing, there is provided process fluid adjuster 100.Adjuster 100 includes adjuster master Body 102, regulator body 102 has fluid intake 104 and fluid issuing 106.In embodiment, Regulator body 102 can accommodate typical equilibrium and non-equilibrium valve cylinder.Bonnet 108 accommodates negative Carry spring 110 and set point adjustment mechanism 112.Balance cartridge module 150 is located at fluid in valve body 102 Between entrance 104 and fluid issuing 106, to adjust fluid pressure downstream.

Adjuster 100 also includes diaphragm 114, and diaphragm 114 does to the downstream pressure in room or opening 116 Go out response.Diaphragm 114 can be moved in bonnet 108.As shown in Figure 1, diaphragm 114 can edge Center longitudinal axis L1 is moved, and the outlet fluid pressure in by opening 116 is produced on diaphragm 114 The position balanced each other with the power that produced on diaphragm 114 by spring loaded 110 of power.Diaphragm 114 by every Plate 54 is supported and/or strengthened.Dividing plate 54 supports diaphragm 114 simultaneously to serve as force transfer mechanism, by power from Spring loaded 110 is delivered to diaphragm 114.Spring loaded 110 is arranged in dividing plate 118 and spring button 120 Between.Adjusting screw 122 is arranged in the opening 124 in bonnet 108.Adjusting screw 122 can be Displacement in opening 124, so that an end abutment spring button 120 of adjusting screw 122.Adjustment The movement of screw 122 causes position movement of the spring button 120 in bonnet 108, and so as to can To change the spring force acted on from spring loaded 110 on dividing plate 118.In this way, it is possible to adjust The set point of adjuster 100.

In order to promote the adjustment to adjusting screw 122, can be by kob plug-in unit 128 and nut Adjusting screw 122 is connected to kob 126 by 130.The opening in kob 126 can be passed through 132 cause nut 130 to be come-at-able, and opening 132 can be covered by stopple 134.

Fig. 2 and Fig. 3 show exemplary cartridge module 150.It should be understood that cartridge module 150 can include appointing The additional assemblies and/or structure (for example, hole, cap, threaded connection, plug, bar, spring etc.) of meaning quantity, They can help it to operate, but in order to concisely no longer be described in detail in.Cartridge module 150 can be wrapped Include guard ring 152 and cylinder 170.Regulator body 102 described in reference diagram 1 is further defined by fluid flow path, Fluid intake 104 is connected to fluid issuing 106 by fluid flow path, so that opening 116 and stream Body flow path is communicatively arranged.Guard ring 152 is at least partially disposed on opening for regulator body 102 In mouth 116, and the centre bore 154 with the extensions of L1 along its longitudinal axis and the end along centre bore 154 156 countersunks 158 for being formed or notch.In some instances, countersunk 158 can surround centre bore 154 outward flange.Countersunk formed surface 160,162, they can with point, curve or it is any its Its suitable structure intersects.In an exemplary embodiment, in first surface and second surface 160,162 Between formed angle be acute angle.

Cylinder 170 is suitable to be at least partially disposed in the centre bore 154 of guard ring 152 along center longitudinal axis L1, And including end sections 172, end sections 172 have surface 174, and surface 174 can Shi Cong centers Longitudinal axis L1 is radially extended and/or prominent outer surface.Once cylinder 170 is at least partially disposed on guard ring In 152 centre bore 154, the countersunk 158 of guard ring 152 and the surface 174 of cylinder 170 form depression Area, such as link slot.

In some instances, surface 162,174 forms the side wall of depressed area.Surface can be plane, Arch or plane and arch combination.In an exemplary embodiment, radially extend from center longitudinal axis L1 Surface 174 and center longitudinal axis form acute angle so that surface 174 is on the direction into depressed area Extend.End sections 172 can also form generally chamfer.As shown in Figure 3, gained To the shape of cross section of depressed area can be usually formed dovetail groove.In other words, depressed area can have There is the wall for tapering inwardly.It should be understood that the either or both on surface 162,174 can inwardly into Taper.

Due to forming depressed area by the combination of guard ring 152 and cylinder 170, conventional tool can be used for shape Into surface 160,162 and 174.For example, can be formed via combined countersink drill or similar cutting tool and be buried Head bore 158, and surface 174 can be formed via chamfering cutting tool or beveling cutting tool.Other Example is also possible.

Cartridge module 150 can include any number of containment member, such as double-curved surface connector (such as O Shape ring) 182,184, it may be adapted to be at least partially disposed in depressed area.Containment member 182, 184 can be formed by any number of suitable material.In some instances, containment member 182,184 With generally rounded cross section, it should be appreciated that if desired, containment member 182,184 can With with cross section of different shapes.Because depressed area has the side wall for generally tapering inwardly, sealing The circumference of component 182 at least about half can be contained or sealed in depressed area, to prevent from not making A component temporary deformity in component or containment member 182 is removed easily in the case of removing.This Sample, containment member can be securely disposed in depressed area and serve as seal.Refer again to Fig. 1, Containment member 184 is arranged between regulator body 102 and guard ring 152.

It will be appreciated by those skilled in the art that without departing from the scope of the invention, Ke Yixiang For above-described embodiment makes various modifications, change and combination, and by this modification, change and group Conjunction is considered as in the range of innovative concepts.
