Description
Technical field
The present invention relates to a kind of valve more particularly to a kind of rotary manual regulating valves.
Background technique
Regulating valve well known to existing majority is in flow field and is easy to generate vibration and noise；In small guide vane, valve
Locate pressure drop maximum, vibration and noise also show the most prominent；It is frequently accompanied by and cavitation, erosion phenomenon occurs, cause valve internal component
Sealing surface damages in a short time.There are a variety of labyrinth speed limit throttling sets both at home and abroad now, this kind of labyrinth type or Cascade
Speed limit throttling set is not only easy to block, and erosion is also extremely serious after a period of use.
Summary of the invention
The present invention provides that a kind of structure is simple, easy to adjust, precise control, integral strength in order to solve problem above
High, wear-resistant, good seal performance, rotary manual regulating valve with long service life.
The technical scheme is that the regulating valve includes bottom flange, valve body, valve seat, spool, valve rod, filler, pad
Piece, bonnet, gland and handle, the valve rod, spool, valve seat constitute flow control device, and the bottom flange setting exists
Regulating valve bottom, the valve body setting is on bottom flange top, and the flow control device is arranged in valve body, the valve
Opposite revolution is controlled by valve rod between core and valve seat, the spool is cylindrical and is provided with window, the valve rod top
It is connected with handle, the bonnet, is fixed at valve body top, the engaging portion setting between the bonnet, and valve body
Gasket, the filler are arranged on the outside of valve rod, and the gland is arranged in bonnet,.
The handle angle of revolution is no more than 60 °.
The gasket is the compound flexible graphite gasket of stainless steel.
Flow scale is carved on the handle.
The configuration of the present invention is simple, easy to adjust, precise control, integral strength is high, wear-resistant, good seal performance, uses the longevity
Life length, uninterrupted as needed, by the scale rotational handle on handle, band ovable valve stem is so that between spool and valve seat
Opposite revolution, controls the opening size of window, to achieve the purpose that accurately control.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 is bottom flange in figure, and 2 be valve body, and 3 be valve seat, and 4 be spool, and 5 be valve rod, and 6 be filler, and 7 be gasket, and 8 be upper valve
Lid, 9 be gland, and 10 be handle.
Specific embodiment
A kind of rotary manual regulating valve, the regulating valve include bottom flange 1, valve body 2, valve seat 3, spool 4, valve rod 5,
Filler 6, gasket 7, bonnet, 8, gland 9 and handle 10, the valve rod 5, spool 4, valve seat 3 constitute flow control device, institute
The setting of bottom flange 1 stated is in regulating valve bottom, and the valve body 2 is arranged on 1 top of bottom flange, and the flow control device is set
It sets in valve body 2, opposite revolution is controlled by valve rod 5 between the spool 4 and valve seat 3, the spool 4 is cylindrical simultaneously
It is provided with window, 4 outer wall of spool is equipped with groove, is equipped with gasket in the groove, 5 top of valve rod is connected with
Handle 10, the bonnet, 8 are fixed at 2 top of valve body, the engaging portion setting between the bonnet, 8 and valve body 2
Gasket 7, the setting of filler 6 can choose in 5 outside of valve rod, the filler according to the difference of regulating valve operating temperature
PTFE or soft graphite, the gland 9 are arranged in bonnet, 8.
10 angle of revolution of handle is no more than 60 °.
The gasket is the compound flexible graphite gasket of 7 stainless steels.
Flow scale is carved on the handle 10.
Above embodiments are only to illustrate the invention and not limit technical solution described in the invention；Cause
This, is although this specification has been carried out detailed description to the invention referring to above-mentioned each embodiment, this field
It is to be appreciated by one skilled in the art that still can modify to the invention or equivalent replacement；And all do not depart from this
The technical solution and its improvement of the spirit and scope of innovation and creation, should all cover the scope of the claims in the invention
In.
