Description
Technical field
The utility model is related to valve technology field, specifically a kind of gas balance decompression large flux control valve.
Background technology
Regulating valve is that in industrial automation process control field, the control exported by receiving regulation unit is believed
Number, go to change the final control element of the technological parameters such as rate-of flow, pressure, temperature, liquid level by power operation.
During the use of large flux control valve, encounter sometimes flow very big situation when, easily cause valve element
The phenomenon being shifted by, causes regulating valve when opening or closing, it is impossible to handle properly completely, and influence uses result.
The content of the invention
The utility model utilizes to overcome the deficiencies in the prior art to be depressured large flux control valve there is provided a kind of gas balance
The design of valve element lower end deflector, can be very good, in the case where flow is very big, to carry out the effect of water conservancy diversion, prevent valve element from offseting
Phenomenon.
To achieve the above object, a kind of gas balance decompression large flux control valve, including valve rod, valve body, bonnet are designed, its
It is characterised by：The lower end of bonnet is connected by screw bolts valve body；Valve rod is connected positioned at the middle part of valve body, valve is run through on the top of valve rod
Lid；The lower end of valve rod is connected with valve element, and the lower end of valve element connects deflector using rotating shaft；Upper set is provided with positioned at the upper end of valve element
Cylinder, the lower end of valve element is provided with valve seat；Lower sleeve is provided between described upper bush and valve seat.
Described deflector is sector structure, and the surface of deflector is curved-surface structure.
Guide sleeve is provided between the top of valve rod and bonnet, the top of guide sleeve, which is provided with above bushing, bushing, to be set
There is filler group, the top of filler group is provided with gland.
The upper end of described bonnet is arranged with clip, and the upper end of valve rod is arranged with pressing plate, and pressing plate is using bolt and card
Hoop connection.
The utility model is compared with the existing technology depressured large flux control valve there is provided a kind of gas balance, using under valve element
The design of deflector is held, can be very good, in the case where flow is very big, to carry out the effect of water conservancy diversion, prevent showing for valve element skew
As.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Referring to Fig. 1,1 is valve body, and 2 be rotating shaft, and 3 be valve seat, and 4 is have valve element, and 5 be upper bush, and 6 be bonnet, and 7 be guiding
Set, 8 be bushing, and 9 be filler group, and 10 be gland, and 11 be clip, and 12 be pressing plate, and 14 be valve rod, and 15 be lower sleeve, and 16 are
Deflector.
Embodiment
The utility model is described further below according to accompanying drawing.
As shown in figure 1, the lower end of bonnet 6 is connected by screw bolts valve body 1；Valve rod 14, valve rod are connected positioned at the middle part of valve body 1
Bonnet 6 is run through on 14 top；The lower end of valve rod 14 is connected with valve element 4, and the lower end of valve element 4 connects deflector 16 using rotating shaft 2；
Upper bush 5 is provided with positioned at the upper end of valve element 4, the lower end of valve element 4 is provided with valve seat 3；It is provided between described upper bush 5 and valve seat 3
Lower sleeve 15.
Deflector 16 is sector structure, and the surface of deflector 16 is curved-surface structure.
Guide sleeve 7 is provided between the top of valve rod 14 and bonnet 6, the top of guide sleeve 7 is provided with bushing 8, bushing 8
Top is provided with filler group 9, and the top of filler group 9 is provided with gland 10.
The upper end of bonnet 6 is arranged with clip 11, and the upper end of valve rod 14 is arranged with pressing plate 12, and pressing plate 12 using bolt with
Clip 11 is connected.
Using the design of valve element lower end deflector, it can be very good, in the case where flow is very big, to carry out the effect of water conservancy diversion,
The phenomenon for preventing valve element from offseting；And deflector is made up of plastics, deflector is sector structure, and the surface tool of deflector
There is certain radian curved-surface structure, to not resulting in impact by the medium of valve body, the effect with certain drainage.
