Description
Technical field
The utility model is related to a kind of operating mechanisms of the anti-seawater corrosion shuttle-type valve for valve field.
Background technology
The transmission of traditional shutoff valve or screw down nonreturn valve uses turbine and worm mechanism or link mechanism.Turbine and worm
Mechanism due to turbine need with worm screw radially side by side, causing the spacing between worm screw and radome fairing larger, can not make worm screw with it is whole
Closing chamber is formed between stream cover.When working under Seawater operating mode, Seawater is to the stress such as valve rod, turbine and worm or driving member
It causes to corrode, if the silt in Seawater enters between driving cog spoke, the damage that can also cause tooth surface is even stuck
Valve；The space requirement bigger of linkage, can not more realize the sealing between valve rod and radome fairing, and linkage
Driving torque is smaller.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of behaviour of anti-seawater corrosion shuttle-type valve
Make mechanism, using the shuttle-type valve of the mechanism, medium and valve rod, gear into shuttle-type valve etc. will not contact directly, and valve moves
Make dependable performance, service life is long.
Realizing a kind of technical solution of above-mentioned purpose is：A kind of operating mechanism of anti-seawater corrosion shuttle-type valve, including driving
Device, valve rod, connection gear and choking device；
The valve rod is vertically arranged, and the upper end is connected with the driving device, and its underpart is located in the radome fairing of valve,
Lower end processes to form bevel gear；
The connection gear is coaxially disposed with the valve rod, and the connection gear is and the matched cone tooth in the valve rod lower end
Wheel, and be connected with the bevel gear of the valve rod lower end；
The connection gear is connected by trapezoidal thread with the choking device.
Further, set in the connection gear there are one gland, the connection gear is existed by the gland /V
In the radome fairing, it is only capable of rotating.
Further, 0 shape sealing ring is equipped between the gland and the tooth connection gear member, between the gland and radome fairing
Equipped with O-ring seals.
Further, stuffing-box is equipped between the valve rod and valve body and radome fairing.
Further, 0 shape sealing ring is equipped between the stuffing-box and valve body, 0 is equipped between the stuffing-box and radome fairing
Shape sealing ring.
Further, the driving device is Vidacare corp or manual driving device, and manual driving device is handwheel
Or handle.
The operating mechanism of a kind of anti-seawater corrosion shuttle-type valve of the utility model, using cone tooth on valve rod in shuttle-type valve
Mechanism is taken turns, and bevel gear mechanism is made to be connected with choking device, to realize that the torque drive control valve door from valve rod to choking device opens and closes.
The set system bulk is small, in the enclosure space for the radome fairing that can be provided entirely in shuttle-type valve, and passes through stuffing-box and realizes medium
With isolating for valve rod, the reliability of valve in use ensure that, improve the service life of valve.
Description of the drawings
Fig. 1 is a kind of structure diagram of the operating mechanism of anti-seawater corrosion shuttle-type valve of the utility model.
Specific embodiment
In order to preferably understand the technical solution of the utility model, below by specifically embodiment and combine
Attached drawing is described in detail：
Referring to Fig. 1, a kind of operating mechanism of anti-seawater corrosion shuttle-type valve of the utility model, including driving device, valve
Bar 2, connection gear 3 and choking device 4.In the present embodiment, driving device is to be arranged on the handwheel 1 of valve stem top.Actually should
In, Vidacare corp also can be used in driving dress.
Valve rod 2 is vertically arranged in valve body 51, and the lower part of valve rod 2 is located in the radome fairing 52 of valve, the lower end of valve rod 2
Processing forms bevel gear.Connection gear 3 and valve rod are coaxially disposed, connection gear 3 be with the matched bevel gear in 2 lower end of valve rod, with
Valve rod 2 is connected by bevel gear pair.It is set in connection gear 3 there are one gland 6, gland 6 is act as to connection gear 3 whole
/V is carried out in stream cover 52, only connection gear 3 is allowed to rotate.Connection gear 3 is connected by trapezoidal thread and choking device 4
It connects.
In order to further ensure that the sealing performance of the operating mechanism of the anti-seawater corrosion shuttle-type valve of the utility model, in valve rod
Stuffing-box 7 is equipped between 2 and valve body 51 and radome fairing 52.Stuffing-box 7 can protect valve rod 2 during valve opening and closing with medium not
It is contacted.0 shape sealing ring 8 is equipped between gland 6 and tooth connection gear member 3 simultaneously, O shapes are equipped between gland 6 and radome fairing 52 and are sealed
Circle 8 is equipped with 0 shape sealing ring 8 between stuffing-box 7 and valve body 51,0 shape sealing ring 8 is equipped between stuffing-box 7 and radome fairing 52, to strengthen
The sealing performance of system.
When 1 driving stem 2 of handwheel rotates, valve rod 2 drives gear pair to rotate, the gear pair in connection gear 3
By trapezoidal thread choking device 4 will be driven to move back and forth after 90 degree of driving force deflecting, so as to fulfill the keying control for valve
System.
The utility model has the following advantages compared with traditional shuttle-type valve：
1) medium and valve rod 2, gear 3 etc. will not contact directly, and the performance of valve is reliable, and service life is longer, can
For Seawater, medium containing silt, containing a variety of corrosivity such as solid particle medium or containing solid particle medium.
2) the driving moment smaller of valve.
3) structure of valve is simple, compact, light-weight.
4) maintenance of valve and repair more convenient and quicker.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this practicality is new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
Variation, the modification of embodiment will all fall in the Claims scope of the utility model.
