Description
Technical field
The utility model relates to a kind of modulating valve, particularly relates to a kind of valve seat type long lifetime single-seat adjusting valve able to quickly change.
Background technique
Although single-seat adjusting valve has the advantages such as compact structure, droop loss is few, water leakage is little, Flow characteristics is accurate, be specially adapted to allow the workplace that before and after little, the valve of leakage rate, pressure reduction is little.But the valve seat of the single-seat adjusting valve of prior art is threaded connection mode and is installed on valve body lumen, need to mount and dismount by special tool, cause product install, field maintenance change extremely inconvenient, and medium, very easily by the thread gaps generation seepage between valve seat and valve body, will inevitably cause valve seat long term seal performance not easily to ensure after Long-Time Service when valve closing.
In addition, between the valve rod of the single-seat adjusting valve of prior art and valve gap, just compress by Gland the stuffing box packing be contained among valve gap stuffing box and realize valve stem seal, prevent medium from leaking outside.If when being applied to containing fine particle impurity fluid or powdery fluid condition, because of impurity particle, powdery medium, the dust of disperse in working environment is also had very easily to invade in the gap between valve rod and stuffing box packing, cause stem wear thus cause medium to leak outside, affecting normal use and the working life of valve.
Summary of the invention
The purpose of this utility model is to provide the mounting or dismounting of a kind of valve seat and changes conveniently, stem packing sealing and valve base sealing excellent durability, the valve seat type long lifetime single-seat adjusting valve able to quickly change of long service life, to overcome the deficiency that prior art exists.To achieve these goals, one of the present utility model valve seat type long lifetime able to quickly change single-seat adjusting valve, comprise valve body, valve seat, spool, valve rod, valve cage, preloading spring, stud nut, valve gap, stuffing box packing, Yx RunddichtringO, O RunddichtringO, Gland and dust-proof seal ring, equipped valve cage on the valve seat arranged in valve body lumen, valve gap is arranged in valve body and valve cage clamping sleeve is contained on valve seat by flange, described spool lower end and valve seat adaptation, spool upper end is connected with valve rod, and valve rod upper end is through described valve gap, preloading spring is installed additional successively in valve gap stuffing box, stuffing box packing, and compress with Gland, it is characterized in that: the upper and lower surface shape of described valve seat, size is identical to be used interchangeably, be contained in the positioning hole of valve body lumen by the direct clamping sleeve of valve cage.
As preferably, the middle part of described valve cage is provided with the pilot hole play the guiding role when moving up and down for valve rod.
As preferably, described Gland coordinates the lower end of endoporus to add Yx RunddichtringO with valve stem slides, and itself and valve gap stuffing hole matching part are also provided with O RunddichtringO.
As preferably, described Gland coordinates the upper end of endoporus to add dust-proof seal ring with valve stem slides.
The beneficial effect that the utility model can bring:
1, valve seat of the present utility model utilizes the direct clamping sleeve of valve cage to be loaded in the positioning hole of valve body lumen, instead of be threadedly connected with valve body, therefore install and remove without the need to special tool, and installation, maintenance is changed very convenient; And the upper and lower surface shape of valve seat, size is identical is used interchangeably, there are comparatively wearing and tearing once sealing surface of seat or damage, only need take valve apart can continue to use by after the upset of valve seat top and bottom again assembling, really achieve on-line maintenance, both improve and safeguarded convenience, can greatly save using and satisfied cost again.
2, due to the sealing surface of spool, valve seat have valve cage around protection, avoid the direct erosion of medium to spool, sealing surface of seat, effectively can improve the working life of spool, valve seat.
3, because valve cage is directly provided with stem guiding hole, decrease the independent pilot cover that common single-seat adjusting valve needs to install additional, both simplified product structure, and stem guiding precision can be improved again, effectively improve its action stability.
4, because of Gland coordinated endoporus to add with valve stem slides Yx RunddichtringO, dust-proof seal ring; O RunddichtringO is also provided with valve gap stuffing hole matching part; can prevent the dust granules in impurity particle, powdery medium and working environment from invading in the gap between valve rod and stuffing box packing; Pleiotropic Protections is played to valve rod, thus effectively extends valve working life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
In embodiment as shown in Figure 1, comprise valve body 1
,valve seat 2, spool 3, valve rod 4, valve cage 5, preloading spring 6, stud nut 7, valve gap 8, stuffing box packing 9, Yx RunddichtringO 10, O RunddichtringO 11, Gland 12 and dust-proof seal ring 13.Valve seat 2 is provided with in the lumen of described valve body 1, equipped valve cage 5 on described valve seat 2, valve gap 8 is arranged in valve body and valve cage 5 clamping sleeve is contained on valve seat 2 by flange, the lower end of described spool 3 and valve seat 2 adaptation rise and regulate and seal action, the upper end of spool 3 is connected with valve rod 4, and valve rod 4 upper end can be connected with actuator through described valve gap 8.Preloading spring 6, stuffing box packing 9 is installed successively additional in stuffing box between valve gap 8 and valve rod 4, and compress with Gland 12, it is characterized in that upper and lower surface shape, the size of described valve seat are identical, be used interchangeably, be contained in the positioning hole of valve body lumen by the direct clamping sleeve of valve cage 5.Once find that sealing surface of seat weares and teares, when making water leakage cannot meet technological requirement, after only need taking valve gap 8 apart, valve cage 5, spool 3 can be taken out easily, reinstall valve body positioning hole after being overturn the top and bottom of valve seat 2, again install spool, valve cage, can continue after fastening good valve gap to use, really achieve on-line maintenance, both improve and safeguarded convenience, can greatly save using and satisfied cost again.
