Abstract
The utility model provides a split-type high-pressure angle-type regulating valve which is characterized by comprising an upper valve body (3) and a lower valve body (1). A valve seat (2) is arranged between the upper valve body (3) and the lower valve body (1), a first gasket (8) is arranged between the valve seat (2) and the lower valve body (1), a second gasket (11) is arranged between the upper valve body (3) and the valve seat (2), and the upper valve body (3) is fixedly connected with the lower valve body (1) through a stud (7). According to the split-type high-pressure angle-type regulating valve, a valve body is divided into two sections, namely the upper valve body and the lower valve body, and the upper valve body is separated from the lower valve body by means of the valve seat, so machining requirements are reduced, and meanwhile process requirements are well met.
Description
Technical field
The utility model relates to the valve field, especially a kind of Split high pressure angle type control valve.
Background technique
High pressure angle regulating valve, extensive use and chemical industry, metallurgy, oil, especially domestic synthetic ammonia and urea high-pressure section project.Present high pressure angle regulating valve, valve body are generally as a whole.When making, the increase of overall volume can cause rough-cast or Forging Technology to strengthen, and then affects difficulty of processing like this.In actual applications, modulating valve will play the effect of an adjusting process, so on the throttleng surface of modulating valve, dwindling of orifice size, the flow velocity of medium can accelerate suddenly, and valve body is at the leading portion of throttling and the back segment of throttling, the abominable degree of suffered operating mode is not identical, easily causes the damage of valve body.
The model utility content
In order to solve the deficiencies in the prior art, provide a kind of Split high pressure angle type control valve.
In order to achieve the above object, solution of the present utility model is: a kind of Split high pressure angle type control valve, comprise upper valve body 3 and lower valve body 1, be provided with valve seat 2 between upper valve body 3 and the lower valve body 1, be provided with the first pad 8 between valve seat 2 and the lower valve body 1, the first pad 8 can make lower valve body 1 reach the effect that seals with the external world, be provided with the second pad 11 between upper valve body 3 and the valve seat 2, the second pad 11 can make upper valve body 3 reach the effect that seals with the external world, and upper valve body 3 is fixed connection with lower valve body 1 by stud bolt 7.
According to the technical solution of the utility model, stud bolt 7 is provided with nut 6, by tightening nut 6, regulates the distance between upper valve body 3 and the lower valve body 1 during work.
According to the technical solution of the utility model, be provided with spool 4 in the upper valve body 3, spool 4 is provided with stuffing box 5, can make like this sealing in spool 4 and the external world.Be provided with above the stuffing box 5 for the Gland 9 that compresses stuffing box 5, be provided with above the Gland 9 for the fixing hold-down grid 10 of Gland 9, hold-down grid 10 is fixedly connected with upper valve base 3 by bolt 12.
According to the technical solution of the utility model, spool 4 is close to valve seat 2 when closing, adjust aperture according to process adjustments during work.
The beneficial effects of the utility model: because septum valve has adopted valve body is divided for two-part, be respectively upper valve body and lower valve body, and separated by the valve seat end, when reducing processing request, can better meet technological requirement like this.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is sectional view of the present utility model.
Reference character is among the figure: 1 for lower valve body, 2 is valve seat, and 3 is upper valve body, and 4 is spool, and 5 is stuffing box, and 6 is nut, and 7 is stud, and 8 is the first pad, and 9 is Gland, and 10 is hold-down grid, and 11 is the second pad, and 12 is bolt.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
Referring to a kind of Split high pressure angle type control valve shown in Figure 1, comprise upper valve body 3 and lower valve body 1, be provided with valve seat 2 between upper valve body 3 and the lower valve body 1, be provided with the first pad 8 between valve seat 2 and the lower valve body 1, the first pad 8 can make lower valve body 1 reach the effect that seals with the external world, be provided with the second pad 11, the second pads 11 between upper valve body 3 and the valve seat 2 and can make upper valve body 3 reach the effect that seals with the external world, upper valve body 3 is fixed connection with lower valve body 1 by stud bolt 7.Stud bolt 7 is provided with nut 6, by tightening nut 6, regulates the distance between upper valve body 3 and the lower valve body 1 during work.Be provided with spool 4 in the upper valve body 3, spool 4 is close to valve seat 2 when closing, and can adjust aperture according to process adjustments during work.Spool 4 is provided with stuffing box 5, can make like this sealing in spool 4 and the external world.Be provided with above the stuffing box 5 for the Gland 9 that compresses stuffing box 5, be provided with above the Gland 9 for the fixing hold-down grid 10 of Gland 9, hold-down grid 10 is fixedly connected with upper valve base 3 by bolt 12.
The utility model add man-hour can be with the valve body separate machined, when reducing processing request, can better meet technological requirement like this.Then be fixed together by stud, only need like this nut above the stud is unclamped in maintenance, just just separately maintenance of valve body facilitates maintenance like this.
The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
