Abstract
A high-pressure right angle once-through cut-off throttle includes a valve cap, a valve body, a circulation cavity inside the valve body, a sealing cap used for the valve in the joint of the bonnet and the valve body, a throttle valve lever consisting of a switch screw and a cut-off screw, a feeding case positioned on the sealing cap, the eteline padded in the feeding case and a pressing ring used to press the padding materials tight and fitted over the throttle valve lever. The sealing cap is fastened by the bonnet and the valve body that are connected through the screws. The throttle valve lever goes through the bonnet and the gland cover reaching the circulation intracavity of the valve body. The switch screw is connected to the bonnet via the thread screws. The utilization of this high-pressure right angle once-through throttle greatly eliminates the problem of undersealing in the former high-pressure right angle once-through cut-off throttle and significantly improves the production efficiency and product quality.
Description
Technical field
The utility model relates to valve field, is the straight-through cut-off throttle valve in a kind of high pressure right angle specifically.
Background technique
In hydraulic pressure installation, the valve part that is absolutely necessary, the quality of valve mass directly influences the performance of device.In all performances of valve, sealing problem is crucial.The straight-through cut-off throttle valve in high pressure right angle is as representative one of the most frequently used in the valve, more use is all arranged in various industrial production, for example in the production of synthetic ammonia and urea, the straight-through cut-off throttle valve in high pressure right angle is as main component, being widely used of process units.But, because there is poorly sealed problem in the straight-through cut-off throttle valve in existing high pressure right angle, directly influenced the output and the quality of product in producing, hindered the raising of manufacturing efficiency and quality of product greatly.
Particularly, the straight-through cut-off throttle valve in existing high pressure right angle mainly contains following shortcoming:
1, poorly sealed, along throttle valve lever the phenomenon of leakage is arranged;
2, operation inconvenience needs very big power just can make it action;
3, working life is short;
4, the structure heaviness is simplified inadequately.
Summary of the invention
At said circumstances, this use is novel to have proposed a kind of promptly have fine sealing effect, the very light straight-through cut-off throttle valve in high pressure right angle again.
For achieving the above object, the novel solution of this use is: a kind of high pressure right angle leads directly to cut-off throttle valve, it includes valve gap, valve body, flowing lumen in the valve body, be built in valve gap valve body joint and be used to seal the stuffing box gland of this valve, throttle valve lever, be located at the Stuffing box on the stuffing box gland, insert the filler of Stuffing box and be enclosed within the pressure ring that on the throttle valve lever filler is compressed, bolted valve gap valve body is fastening with stuffing box gland, described throttle valve lever is divided into the switch screw rod and cuts off screw rod, switch screw rod and valve gap are by being threaded, rotation by the switch screw rod is exerted pressure to cutting off screw rod, thereby promote its knee-action, carry out flow control.
Described Stuffing box is the set cavity of stuffing box gland upper edge throttle valve lever periphery specifically.This Stuffing box is positioned at the top of stuffing box gland.Described filler is specially tetrafluoroethylene.
The use of the straight-through cut-off throttle valve in this high pressure right angle has improved the straight-through poorly sealed problem of cut-off throttle valve in original high pressure right angle greatly, has promoted manufacturing efficiency and quality of product.
Specifically, the utility model has following advantage:
1, good seal has improved the leakage problem greatly;
2, make things convenient for operation, used very little power just can make its action;
3, long service life;
4, structure is simplified.
Describe the utility model in detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the utility model embodiment's a structural drawing.
Specific implementation
As Fig. 1 is the utility model embodiment's structural drawing, as shown in the figure, the utility model embodiment specifically include flowing lumen (3) in the valve gap (2), valve body (1), valve body (1), be built in valve gap (2) valve body (1) joint be used to seal the stuffing box gland (4) of this valve, by switch screw rod (10) with cut off throttle valve lever (5) that screw rod (11) forms, be located at Stuffing box (6) on the stuffing box gland (4), insert the filler (7) of Stuffing box (6) and be enclosed within the pressure ring (8) that on the switch screw rod (10) filler (7) is compressed.Valve gap (2) is connected by bolt (9) with valve body (1), valve gap (2), valve body (1) have also been compressed stuffing box gland (4) in the time of fastening, throttle valve lever (5) passes valve gap (2) and stuffing box gland (4), cut off screw rod (11) and extend in the flowing lumen (3), switch screw rod (10) and valve gap (2) are by being threaded.This flowing lumen (3) is divided into perpendicular chamber and horizontal chamber, and the head that cuts off screw rod (11) just drops on the connecting part in perpendicular chamber and horizontal chamber.Locate at stuffing box gland (4) the tight obedient switch screw rod in top (10), also offer above-mentioned Stuffing box (6), be filled with filler (7) in it, pressure ring (8) is pressed on the filler (7).
The utility model embodiment is used for the hydraulic pressure process units, the process units of synthetic ammonia and urea for example, its working mechanism is such: as shown in Figure 1, ammoniacal liquor flows into the utility model embodiment by the perpendicular chamber of flowing lumen (3), as required, can locate screw thread by rotary switch screw rod (10) and valve gap (2) and push or draw high cut-out screw rod (11), flow with the control ammoniacal liquor, this method that realizes flow control that draws high by extruding, substituted original method of directly carrying out flow control by rotary barrel throttle bar (5), not only make things convenient for operation, also improved the utility model embodiment's working life.Because between stuffing box gland (4) and the switch screw rod (10) space is arranged, its sealing is not very tight, the pressure of ammoniacal liquor is very big again, so be easy to cause ammoniacal liquor to be leaked to valve gap (2) lining, be leaked to the outside at last, serious also may damage the utility model embodiment, thereby causes big economic loss.In addition,, just reduced the pressure reduction of valve body (1) and valve gap (2), like this, when opening the utility model embodiment, just required great effort very much, influenced manufacturing efficiency if ammoniacal liquor is leaked to valve gap (2) lining.On stuffing box gland (4), be provided with Stuffing box (6), and fill out the filler (7) of waterproof, use pressure ring (8) to compress again, so just can avoid the leakage of ammoniacal liquor, reached good using effect, thereby improved manufacturing efficiency greatly.
