Description
Technical field
The utility model belongs to mechanical engineering valve technology field, and in particular to a kind of locking of ball screw type stop valve
Device.
Background technology
Valve is a kind of pressure pipeline element, and it is situated between for changing pipeline section and media flow direction, control conveying
The pressure of matter, flow, a kind of device of temperature.In national economy, valve is indispensable industrial pipeline annex and equipment
One of.Stop valve, pipe valve is also, because frictional force is small between sealing surface during its opening and closing, durability is preferable, and Lift is not
Greatly, easy to manufacture, easy to maintenance, the features such as suitable for mesolow and high pressure, use is quite varied.According to channel direction, cut-off
Valve mainly has through type, single flow, angie type and plunger type.
Stop valve opening and closing element is flap, generally flat seal and conical surface seal, and center line of the flap along valve seat is made straight
Line moves back and forth, and flap is separated or is closed with the sealing surface of valve seat with ovable valve stem by screw thread pair, so as to realize that stop valve opens
Close.One of stop valve shortcoming is that fluid resistance is larger, and required power is larger during opening and closing, and flap is situated between when especially closing
The impact of matter so that bigger power is needed during closing.
The content of the invention
The purpose of this utility model is to provide a kind of ball screw type that can reduce hoisting capacity and have auto-lock function
The locking device of stop valve.
The locking device of ball screw type stop valve provided by the utility model include valve rod, annular magnetic sheet, locking axle sleeve,
Bonnet and nut, valve rod are divided into four sections from top to bottom, be the screwed side's axis of cone in top, the square shaft at middle part and screw mandrel respectively with
And the Step Shaft of bottom；Annular magnetic sheet is located at the junction of the square axis of cone and square shaft, and locking axle sleeve is located at square shaft and nibbled with bonnet
Close, nut is located at screw mandrel and is connected with bonnet, and nut interior is machined with raceway and is placed with ball；Wherein, the screw mandrel of valve rod
Rolled threads pair is formed with nut.
The utility model coordinates ball and nut, achievable valve rod to move up to open by the screw mandrel of valve rod
Stop valve is closed, operating efficiency can be improved；There is auto-lock function with the valve rod that engages of bonnet by locking device simultaneously.

Embodiment
Embodiment
As shown in Fig. 1~Fig. 6, the locking device for the ball screw type stop valve that the present embodiment provides includes valve rod 1, annular
Magnetic sheet 2, locking axle sleeve 3, bonnet 4 and nut 5, the valve rod 1 are divided into four sections from top to bottom, are the screwed side in top respectively
The axis of cone 11, the square shaft 12 at middle part and screw mandrel 13 and the Step Shaft of bottom 14, its structure are as shown in Figure 2；The square axis of cone 11 be used for
The handwheel connection of stop valve；The junction of the square axis of cone 11 and square shaft 12 is provided with annular magnetic sheet 2, and annular magnetic sheet 2, which is used to adsorb, to be locked
Mandrel set 3, its structure is as shown in Figure 3；Locking axle sleeve 3 is installed, the upper surface of locking axle sleeve 3 is machined with and square shaft on square shaft 12
12 square holes coordinated, are machined with the gear teeth on lower surface, its structure is as shown in Figure 4；Screw mandrel 13 is provided with bonnet 4 and nut 5, bonnet
4 include bonnet body 41, support frame 42 and base 43, and bonnet body 41 is connected by support frame 42 with base 43, and base 43 fixes peace
On stop valve, its structure is machined with and locked on the upper surface of through hole as shown in figure 5, be machined with through hole in bonnet body 41
The gear teeth of the 3 identical number of teeth of axle sleeve, engaged for locking axle sleeve 3 with bonnet 4, hole, nut 5 are threaded on the lower surface of through hole
It is arranged in through hole, and is bolted from the bottom of bonnet body 41, raceway is machined with nut 5 and is placed with ball,
Its structure instead of traditional slip screw thread pair, so as to reduce as shown in fig. 6, screw mandrel 13 and the formation rolled threads pair of nut 5
Power needed for opening and closing cut-off valve；The Step Shaft 14 of the bottom of valve rod 1 is used to connect the seals such as the flap in stop valve.
Workflow of the present utility model：
(1) it is turned on and off stop valve：By square shaft 12 upward sliding of the locking axle sleeve 3 along valve rod 1, and it is adsorbed in annular magnetic
On piece 2, by rotating the handwheel being connected with the top side's axis of cone 11 of valve rod 1, make the attaching nut 5 of screw mandrel 13 and ball of valve rod 1, from
And realize valve rod 1 and move up with opening and closing cut-off valve.
(2) valve rod positioning is maintained at some position：Locking axle sleeve 3 is departed from into annular magnetic sheet 2, and along the square shaft 12 of valve rod 1
Slide downward, locking axle sleeve 3 is finely tuned, it is engaged with bonnet 4；Because the relative stop valve of bonnet 4 remains static, lock shaft
Set 3 can not rotate, the stopping function coordinated along with the square hole of locking axle sleeve 3 with the square shaft 12 of valve rod 1 so that valve rod 1 is locked
In the position.
Described above is only the utility model preferred embodiment, but the scope of protection of the utility model is not limited to
This, any transformation carried out based on technical scheme provided by the utility model and inventive concept and replacement should all be covered in this reality
With in new protection domain.
