Abstract
The utility model provides an adjusting valve used in the metallurgical industry. The utility model comprises a valve body, a valve cover and a valve rod. The valve body is connected with the valve cover through screw bolts. The inner part of the valve body is s provided with an orifice plate, and the orifice plate is dead-linked with the valve body. A valve core is provided inside the orifice plate, and the valve core and the orifice plate reach liquid packing. The orifice plate and the valve core are respectively opened with several rows of holes with consistent shape and size. The holes on the orifice plate and the holes on the valve core are alternatively arranged. The valve rod is fixedly connected with the valve core. The utility model is provided with beneficial effects of simple structure, easy producing, short distance of run and good adjusting performance.
Description
Affiliated technical field
The utility model relates to a kind of valve, particularly relates to a kind of modulating valve.
Background technique
Use at present at modulating valve metallurgical, nuclear power industry, be generally butterfly valve, ball valve and three kinds of forms of stop valve, butterfly valve and ball valve form stroke are short, but control characteristic is an equal percentage curve; Though stop valve form control characteristic is linear, complex structure, stroke is long, need rotate tens circles from standard-sized sheet to the complete shut-down drive unit.
Summary of the invention
In order to overcome existing butterfly valve and deficiencies such as the ball valve adjusting function is bad and the stop valve adjustment stroke is long, the utility model provides the modulating valve that a kind of stroke is short, adjusting function is good.
The technological scheme that its technical problem that solves the utility model adopts is a kind of modulating valve, comprises valve body, valve gap, valve rod, and valve body and valve gap pass through Bolt Connection, orifice plate is housed in the valve body, orifice plate and valve body are fixedly connected, and spool is housed in the orifice plate, and spool and orifice plate reach liquid sealing; Respectively have number row's shape hole of the same size on orifice plate and spool, hole on the orifice plate and the hole on the spool are staggered, and valve rod and spool are fixedly connected.
Hole shape is a rectangle on orifice plate and the spool, also can be circle.
The beneficial effects of the utility model are that valve mechanism is simple, easily manufactured, stroke is short, adjusting function is good.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is embodiment's a tectonic maps.
Fig. 2 is a valve when being in off-position, the position unfolded drawing in hole on orifice plate and the spool.
Fig. 3 is a valve when being in out, the position unfolded drawing in hole on orifice plate and the spool.
Among the figure: 1. valve gap; 2.O shape circle; 3. valve rod; 4. orifice plate; 5. spool; 6. valve body.
Embodiment
As shown in Figure 1, 2, 3, a kind of modulating valve comprises valve body 6, valve gap 1, valve rod 3, and valve body 6 passes through Bolt Connection with valve gap 1, and orifice plate 4 is housed in the valve body 6, and orifice plate 4 is fixedly connected with valve body 6, and spool 5 is housed in the orifice plate 4, and spool 5 reaches liquid sealing with orifice plate 4; Respectively have number row's shape hole of the same size on orifice plate 4 and spool 5, the hole on hole on the orifice plate 4 and the spool 5 is staggered, and valve rod 3 is fixedly connected with spool 5, and valve rod 3 seals by O shape circle 2 with valve gap 1; Hole shape is a rectangle on orifice plate 4 and the spool 5, also can be circle.Fig. 2 valve is in off-position, hole on orifice plate 4 and the spool 5 is staggered, valve is in sealing state, when needing to open, drive unit drives valve rod 3 and spool 5 rises, when spool 5 rises on orifice plate 4 and the spool 5 hole and is in side by side the position, promptly during Fig. 3 position, valve wide open, the length on the also only porose stroke directions of stroke this moment; Can be as required, the traffic requirement of system is satisfied in the position of regulating spool 5.
