Description
Technical field
The utility model relates to a kind of stop valve with sink.Particularly a kind of with flap as closure member, flap open and close travel direction is perpendicular to the stop valve of closing face.
Background technique
By in the equipment of pipeline conveyance fluid medium, need that usually stop valve is installed and cut off or the conducting pipeline, to realize corresponding manufacturing process.Especially in the pipeline of heavy caliber, conveying high-temperature high-pressure medium, the stop valve of being installed is worked under the abominable working condition of High Temperature High Pressure, radiating effect is poor, so that valve is very easily damaged under high temperature and high pressure condition, High Temperature High Pressure causes filler to lose efficacy, stop valve is leaked, thereby make complete equipment stop to produce running, cause heavy losses.
The model utility content
In view of the technological deficiency that prior art exists, the purpose of this utility model is to provide a kind of stop valve with sink, can effectively solve the heat dissipation problem of stop valve, loses efficacy with the bad seals that prevents stop valve.
To achieve these goals, the technical solution of the utility model is:
A kind of stop valve with sink, comprise valve body, support, be installed in the flap that has valve rod in the described valve body, described valve rod links to each other with screw rod by butt joint cutting ferrule device, wherein is provided with the valve pocket that links together with it between described valve body and support, and the outer surface of described valve pocket has radiating fin, described valve rod is one can pass the extension bar of described valve pocket, is provided with filler between the top of described valve pocket and valve rod.
Stop valve with sink, wherein valve body is the angie type valve body.
Stop valve with sink, wherein valve body is the straight-through type valve body.
Stop valve with sink, wherein valve body, valve pocket and the flap that has a valve rod are to make with anti-hydrogen steel (10MoWVNb) at least.
Because after adopting such scheme; the stop valve that the utlity model has sink in use; the valve pocket part is longer; make the stuffing box packing part away from the valve body part, the protection filler is unlikely to overheated and lost efficacy, and at the valve pocket outer surface radiating fin is set; can increase the heat diffusion area of stop valve; minimizing effectively reduces the temperature of valve pocket and stuffing box packing from the conduction heat of valve body to stuffing box packing part, also can avoid valve pocket Yin Wendu rapid change and is out of shape damage.Prolong the stop valve time between failures, guaranteed carrying out smoothly of production.

Embodiment
Be further described below in conjunction with the embodiment of Figure of description the utility model stop valve.
The stop valve with sink as shown in Figure 1, this is the Angle Stop valves that a kind of valve body 3 inlets 1 and outlet 20 are 90 ° of angles.Main parts size comprises valve body 3, inlet flange 2, valve rod 6, butt joint cutting ferrule device 13, valve pocket 18, support 9, screw rod 12, nut 11, handwheel 10, outlet(discharge) flange 19.One end of valve pocket 18 is fixedlyed connected with valve body 3 with bolt 7, and the other end of valve pocket 18 and support 9 are bolted to connection, and constitutes the main body of stop valve.Flap 5 is parts of one with valve rod 6, the sealing surface driving fit mutually of the sealing surface 4 of flap 5 end faces and valve body 3 upper inlets 1 inboard, the mesopore that valve rod 6 passes valve pocket 18 is connected with screw rod 12 by butt joint cutting ferrule device 13, screw rod 12 is formed power screw with the nut 11 on support 9 tops and is paid the fixedly connected handwheel 10 in screw rod 12 tops.In use, rotation hand wheel 10, drive screw rod 12 and rotate, screw rod 12 is paid with the nut 11 composition power screw on support 9 tops, and screw rod 12 is moved upward, by butt joint cutting ferrule device 13, pulling valve rod 6 upwards promotes, and the flap 5 of valve rod 6 lower ends is risen, and the sealing surface 4 of flap 5 breaks away from the sealing surface of valve body 3, make flowing medium 1 enter valve body 3, flow out from exporting 20 through the flap 5 and the gap of the sealing surface 4 of valve body 3 from entering the mouth.When needs are closed stop valve, counterrotating handwheel 10, driving screw rod 12 rotates, screw rod 12 is moved downward,, drive valve rod 6 and move downward by butt joint cutting ferrule device 13, the flap 5 of valve rod 6 lower ends is descended, the sealing surface 4 of flap 5 and the sealing surface driving fit of valve body 3 block from 1 flowing medium that enters valve body 3 that enters the mouth, and outlet 20 stops flowing medium and flows out.By the size of adjusting play, the rate-of flow of the stop valve of can pilot line flowing through.Because valve pocket 18 is set, make seal element away from this thermal source of high temperature media in the valve body 3, valve pocket 18 outer surfaces have radiating fin 8 simultaneously, the high temperature and high pressure flow body medium that leaves is given the heat of stop valve hermetic unit through valve body 3 conduction, reduced the temperature of stop valve hermetic unit, improve the operating conditions of hermetic unit, prolonged the working life of stop valve.Has filling space between valve pocket 18 endoporus and the valve rod 6, pressing plate 15 is sleeved on valve rod 12, material Gland 16 and filler 17 are pressed in the filling space between valve rod 12 and the valve pocket 18, form the dynamic pressure sealing, by bolt 14 pressing plate 15 is fixed on the valve pocket 18, valve rod 6 can rotate lifting when the dynamic pressure seal construction of Gou Chenging made work like this, and the flowing medium that blocks simultaneously in valve body 3 chambeies comes out from the clearance leakage between valve body 3, valve pocket 18 and the valve rod 6.
Employing is provided with valve pocket 18, and the structure that radiating fin 8 is set on valve pocket 18 not only can be used for Angle Stop valves, also can be used for straight-through stop valve.
Because the flowing medium of applying working condition may be to contain hydrogen medium, fertilizer industry for example, make the ferrous materials of stop valve produce the hydrogen embrittlement phenomenon easily, reduce the strength of materials of stop valve, the stop valve premature damage was lost efficacy, thus stop valve at least the material of valve body 3, valve rod 12 and valve pocket 18 can select to use anti-hydrogen steel (10MoWVNb).
