Description
Technical field
The utility model relates to a kind of machinery, especially a kind of high pressure steam control valve.
Background technique
High pressure steam control valve is a kind of broad-spectrum control valve, is mainly used in direction, pressure and the flow of control media while flowing, and is widely used in the industrial fields such as electric power, petrochemical industry, metallurgy, machinery, light textile, papermaking.In this valve, the valve rod 2 that can move along self axis is conventionally positioned and is led (as shown in Figure 3) by the axle sleeve at two ends; Wherein, be positioned with the axle sleeve 5 to stem guiding on bottom flange, the seam areas of axle sleeve upper-end surface and bottom flange upper-end surface is shaped with v-depression, by weld (solder joint 5-3) at v-depression, axle sleeve and bottom flange can be fixed together; The workload (will repeatedly welding part be removed and be welded) when but this structure can increase axle sleeve maintenance and the task of replacing greatly, has greatly affected working efficiency, need further improvement.
Model utility content
The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, and a kind of easily detachable high pressure steam control valve is provided, and this control valve should have advantages of easy accessibility, simple in structure and manufacture cost is lower.
The technical solution of the utility model is: a kind of high pressure steam control valve of being convenient to maintenance, comprise be shaped with steam inlet and steam (vapor) outlet valve body, be arranged on upper valve base and lower valve base in valve body, be positioned in valve body and the valve rod that can move along self axis, be formed on valve rod and the upper flap matching with upper valve base and the lower Disc matching with lower valve base, drive stem movement power mechanism, the bonnet that is arranged on respectively the upper and lower two ends of valve body and bottom flange, be positioned at the axle sleeve on bottom flange and to stem guiding; It is characterized in that: described axle sleeve is rotatably positioned on bottom flange by worm structure.
The upper end of described axle sleeve is shaped with to external diameter direction horizontal-extending and is positioned at the end cap of bottom flange upper-end surface top; End cap edge and bottom flange connected portion connect as one by spot welding.
The beneficial effects of the utility model are:
Between bottom flange of the present utility model and axle sleeve, by worm structure, be connected (spot welding is only to prevent that axle sleeve is loosening), can avoid the drawback of prior welding mode, axle sleeve maintenance and remove very conveniently, has greatly promoted working efficiency and has reduced working strength; Meanwhile, structure of the present utility model is comparatively simple, and manufacture cost is also lower.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of A portion in Fig. 1.
Fig. 3 is the structural representation before Fig. 2 improves.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, an easily detachable high pressure steam control valve, comprises valve body 1, is positioned in valve body and the valve rod 2 that can move along self axis, the power mechanism 3 that drives stem movement and bonnet 4-1 and the bottom flange 4-2 that is arranged on respectively the upper and lower two ends of valve body; On valve body, be shaped with upper valve base 1-5 and lower valve base 1-6 are also installed in steam inlet 1-1 and steam (vapor) outlet 1-2 and valve body; On valve rod, be shaped with the upper flap 2-1 matching with upper valve base and the lower Disc 2-2 matching with lower valve base; Axle sleeve 5 is positioned on bottom flange, for to stem guiding.Said structure and existing valve type are same
Improvement of the present utility model is as follows:
As depicted in figs. 1 and 2, described axle sleeve is rotatably positioned on bottom flange by worm structure 5-1, and this worm structure comprises the screw on bottom flange and is produced on the screw thread matching on sleeve outer circle side face; By rotary sleeve, just can to axle sleeve, carry out installation or removal easily, greatly promote working efficiency and reduced working strength; Simultaneously, the upper end of axle sleeve is shaped with end cap 5-2, the outer of end cap is to external diameter direction horizontal-extending (radius of the outer of end cap is greater than the radius of axle sleeve) and be positioned at top, bottom flange upper-end surface, then carries out spot welding (electrical pads of several point-like) end cap edge and bottom flange connected portion are connected as one; After so can making axle sleeve fixing, can not become flexible, while removing, only need chisel out several solder joints simultaneously.This end cap can be used as the force application part (by increasing the arm of force to reduce application of force intensity) when axle sleeve installation or removal, the working efficiency while further promoting axle sleeve dismounting.
In addition, steam inlet and steam (vapor) outlet adopt not isometrical design, be that (1-2 that the diameter of steam (vapor) outlet is about steam inlet diameter doubly for the diameter of the steam (vapor) outlet diameter that is greater than steam inlet, when multiple is 1.33, using effect is best), contribute to improve the installation efficiency (without separately joining transition pipe joint) of control valve and reduce user cost; Valve body adopts 15Cr1Mo1V material foundry goods; The crucial flow passage parts such as upper valve base and lower valve base, upper flap and lower Disc all adopt that wear-resisting property is good, the 12Cr18Ni9 material forging of long service life; Bonnet and bottom flange adopt 12Cr1MoV material forging.
