Abstract
The utility model discloses a valve for exhausting synthesis ammonia liquid. The valve for exhausting synthesis ammonia liquid comprises a valve rod, a valve seat and a valve body. An exit channel is formed in one side of the valve body. A valve plug is integrally connected with the lower portion of the valve rod. The valve plug can be sleeved in an inner cavity of the valve body in a rotation mode. Part of the valve plug is stretched into an entrance channel of the lower portion of the valve body. An annular body of an annular groove is formed on an outer side of the valve seat, assembled on a plane which is parallel to the exit channel in the valve body and communicated with the exit channel through the annular groove. A flow guiding hole is formed on one side, far from the exit channel, of the valve seat. The valve plug is cylinder-shaped and matched with the valve seat in a sealed mode. A groove communicated with the flow guiding hole is formed on the outer periphery of the valve plug and in the shape of a crescent moon or a rounded rectangle. The valve plug can be well and constantly matched with the valve seat in the valve body in a sealed mode. The length of a flowing trace of liquid ammonia in the valve body can be lengthened, a pressure difference between sealing parts can be relieved, internal leakage is prevented and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of valve for discharging synthetic ammonia liquid.
Background technique
The Ammonia Production of technology, be under condition of high voltage by hydrogen and nitrogen synthetic fluid ammonia from high-pressure bottle to low pressure vessel in discharging so that storage.Usually adopt common height to take modulating valve by force between high-pressure bottle and the low pressure vessel, because the valve long-term work is under the special operation condition condition of head pressure, small flow, the sealing of valve is easy under serious cavitation effect destroyed, leak in occurring, when interior leakage quantity during greater than liquefied ammonia output, even with the valve Close All, the liquefied ammonia that generates in the high-pressure bottle is much emptyings also, cause when putting ammonia a large amount of useful elevated pressure nitrogen hydrogen unstrpped gases are discharged, not only shortened the working life of valve, and can threaten safety in production and cause serious waste.
The model utility content
The valve that is used for discharging synthetic ammonia liquid that the purpose of this utility model is to provide that a kind of intensity is big, long service life, non-internal leakage phenomenon take place solves the shortcoming that prior art exists.
The utility model adopts following technological scheme to realize:
A kind of valve for discharging synthetic ammonia liquid, this valve comprises valve rod, valve seat and valve body, one side of described valve body has outlet passage, the below of described valve rod is connected with valve plug, described valve plug is socketed in the inner chamber of valve body rotationally, valve plug partly extend in the inlet channel of valve body lower portion, described valve seat is the annular solid that the outside has annular slot, be assemblied on the plane parallel with outlet passage in the valve body and by annular slot and outlet passage UNICOM, valve seat also has a pod apertures away from a side of outlet passage, it is characterized in that, described valve plug is the cylinder bodily form, be sealed and matched with valve seat formation, the outer circumferential face of valve plug has the groove with pod apertures UNICOM.
Further, be crescent shape or round rectangle with the groove of pod apertures UNICOM on the outer circumferential face of valve plug.
The useful technique effect that the utility model possesses is:
The below of valve rod is connected with valve plug, and valve plug is cylindrical, can cooperate with the valve seat excellent sealing in the valve body again, leak in preventing and take place, and do not hinder flows of liquid ammonia to go out when opening valve, prolonged the length of flow across of liquid ammonia at valve inner, alleviated the pressure difference between the air locking, the cost of the manufacturing is not high yet.
Description of drawings
Fig. 1 is the utility model first embodiment's cross-sectional view.
Fig. 2 is the utility model second embodiment's cross-sectional view.
Embodiment
By following description to embodiment; to help public understanding the utility model more; but can't the specific embodiment that the claimant is given be considered as the restriction to technical solutions of the utility model, any definition to parts or technical characteristics change and/or to overall structure do form but not the conversion of essence all should be considered as the protection domain that the technical solution of the utility model limits.
The utility model first embodiment as shown in Figure 1, valve comprises valve rod 2, valve seat 4 and valve body 1, one side of valve body has outlet passage 7, the below of valve rod 2 is connected with valve plug 3, valve plug 3 is socketed in the inner chamber of valve body 1 rotationally, valve plug 3 parts extend in the inlet channel 8 of valve body lower portion, valve seat 4 has the annular solid of annular slot 6 for the outside, be assemblied in the valve body 1 on the plane parallel with outlet passage 7 and by annular slot 6 and outlet passage 7 UNICOMs, valve seat 4 also has a pod apertures 5 away from a side of outlet passage 7, valve plug 3 is the cylinder bodily form, can form with valve seat 4 and be sealed and matched, prevent that liquefied ammonia from leaking in producing when valve closing, the outer circumferential face of valve plug 3 has the groove 9 with pod apertures 5 UNICOMs, and groove 9 is shaped as round rectangle in the present embodiment.When needs discharge liquid ammonia in from high-pressure bottle to low pressure vessel, only need rotation valve rod 2 make groove 9 and pod apertures 5 UNICOMs like this, the liquid outflow from outlet passage 7 via groove 9, pod apertures 5, annular slot 6 from inlet channel 8 enters in order to store up.Because the flow direction of liquid ammonia in valve is through repeatedly changing, so stream lengthens, the front and back pressure reduction that is sealed and matched after multistage throttle step-downs such as via hole, groove obviously reduces, cavitation effect also weakens greatly, thereby the sealing effect when having guaranteed valve closing has been avoided interior leakage and has been prolonged working life of valve.
Second embodiment of the present utility model as shown in Figure 2, be that with first embodiment's difference groove 10 is meniscate, can reach equally prolong liquid ammonia in the process of flowing through of valve inner, alleviate the internal pressure difference and guarantee the purpose of sealing effect, the remaining part of present embodiment is identical with first embodiment, so do not give unnecessary details at this.
Certainly; the utility model can also have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
