Abstract
The utility model discloses a high-pressure urea angular adjusting valve, which comprises an upper valve, a lower valve, a valve base, an inflow channel, an outflow channel, an overcurrent cavity, a valve rod and a vale core connected with the valve rod; The utility model is characterized in that a loop boss is arranged on the valve rod; the boss is distributed around the openings; the boss is arranged in the overcurrent cavity which is faced to one side of the valve core; a balanced sleeve is arranged on the boss; one end of the balanced sleeve leans against the end of the valve base; the other end of the balanced sleeve takes a stepped shape and leans against the upper valve; a section of balanced sleeve is in the overcurrent sleeve; a discharge orifice is equally arranged on the section of the balanced sleeve. An anti-crater hole can also be arranged on the balanced sleeve. The utility model of the valve rod is received little lateral force and the guide of valve rod is more steady and reliable; therefore, the abrasion between the valve core and the valve base can be reduced; the utility mole is of long life-span, fine stability, small shaking, low noise, smooth flowing; and the utility model can be used for urea production line.
Description
One, technical field
The utility model relates to the urea plant parts, is specifically related to urea high pressure angle type control valve.
Two, background technique
In 80～nineties, China has introduced some large-scale urea plants, and wherein, the high pressure angle type control valve is the key equipment in the urea production, with an import of urea plant.This high pressure angle type control valve mainly by upper valve body, down valve body, valve seat, influent stream passage, go out circulation road, overcurrent chamber, valve rod and spool and form, for example, 1072 type high pressure angle type control valves of German GULDE company production.At present, the structure of the high pressure angle type control valve of import exists defective and deficiency, and its influent stream passage is with to go out circulation road rectangular, and the influent stream passage with go out circulation road very big pressure reduction arranged, fluid is turned at the overcurrent chamber, and valve rod is produced lateral force, under this working state, the valve rod unbalance stress, vibration is big, and noise is big, very easily damage, even can rupture, spool also can produce eccentric wear, and the working life of whole modulating valve is very short.
Three, summary of the invention
The purpose of this utility model is in order to overcome the deficiency of prior art, provides a kind of long service life, good stability, vibrations are little, noise is little, flow to unimpeded urea high pressure angle type control valve.
The utility model urea high pressure angle type control valve, comprise upper valve body, following valve body, valve seat, the influent stream passage, go out circulation road, the overcurrent chamber, valve rod and the spool that is connected as a single entity with valve rod, be characterized in: on the described valve rod annular boss is set, the uniform gap of described boss, described boss is arranged in the described overcurrent chamber facing to spool one side, on the described boss balancing sleeve is set, one end of described balancing sleeve leans on mutually with the end face of described valve seat, the other end is stepped shaft and leans on mutually with upper valve body, one section described balancing sleeve is arranged in described overcurrent chamber, discharge orifice evenly is set on it.
In the such scheme, anti-plug-hole is set on the described balancing sleeve, described anti-plug-hole is arranged near on the balancing sleeve of described valve seat one side.Anti-plug-hole can prevent less foreign matter bite, if any foreign matter, can flow out from anti-plug-hole along with fluid.
The utility model is owing to be provided with balancing sleeve, fluid is from high pressure influent stream passage, flow out through the valve that forms between spool and the valve seat, be introduced into balancing sleeve, from the balancing sleeve discharge orifice, flow out again, enter the overcurrent chamber, arrive low the extrusion in the circulation road then, rather than directly enter in overcurrent chamber and the low extrusion circulation road.Like this, greatly weakened the lateral force of fluid to valve rod, the guiding of valve rod is more reliable and more stable, has alleviated the wearing and tearing between spool and the valve seat, and its advantage is: long service life, good stability, vibrations are little, noise is little, it is unimpeded to flow to.
Four, description of drawings
Described in detail below in conjunction with the utility model embodiment accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of balancing sleeve described in the utility model;
Fig. 3 is the plan view of valve rod described in the utility model;
Fig. 4 is the sectional view of Fig. 3;
Fig. 5 is the 1072 type high pressure angle type control valve structural representations that German GULDE company produces.
Five, embodiment
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model urea high pressure angle type control valve, comprise upper valve body 1, following valve body 2, valve seat 3, influent stream passage 4, go out circulation road 5, overcurrent chamber 6, valve rod 7 and the spool 8 that is connected as a single entity with valve rod, annular boss 9 is set on the valve rod 7, boss 9 uniform gap 10, boss 9 is arranged in the overcurrent chamber 6 facing to spool 8 one sides, balancing sleeve 11 is set on the boss 9, one end of balancing sleeve 11 leans on mutually with the end face of valve seat 3, the other end is stepped shaft and leans on mutually with upper valve body 1, one section described balancing sleeve 11 is arranged in overcurrent chamber 6, discharge orifice 12 evenly is set on it.Anti-plug-hole 13 also is set on the balancing sleeve 11, and anti-plug-hole 13 is arranged near on the balancing sleeve 11 of valve seat 3 one sides.
Shown in Figure 5 is 1072 type high pressure angle type control valves that German GULDE company produces, it mainly by upper valve body 1, down valve body 2, valve seat 3, influent stream passage 4, go out circulation road 5, overcurrent chamber 6, valve rod 7 and constitute with spool 8 that valve rod is connected as a single entity.
During the work of the utility model urea high pressure angle type control valve, fluid flows out through the valve that forms between spool 8 and the valve seat 3 from high pressure influent stream passage 4, be introduced into balancing sleeve 11, from balancing sleeve discharge orifice 12, flow out again, enter overcurrent chamber 6, arrive the low circulation road interior 5 that extrudes then.Rather than directly enter overcurrent chamber 6 and low the extrusion in the circulation road 5, and must become the structure of prior art, like this, greatly weakened the lateral force of fluid to valve rod 7, the guiding of valve rod 7 is more reliable and more stable, has reduced the wearing and tearing between spool 8 and the valve seat 3.Anti-plug-hole 13 can prevent less foreign matter bite, if any foreign matter, can flow out from anti-plug-hole 13 along with fluid.
