Abstract
The invention relates to a fast ball valve with convenience in adjusting flow. The fast ball valve comprises a valve element, a control cylinder and a positioning machine. The positioning machine is mounted on the control cylinder and is connected with the control cylinder by gauge air pipes, and a valve location feedback device which is connected with the valve element is arranged below the positioning machine and is in signal connection with the positioning machine. Compared with the prior art, the fast ball valve has the advantages that the fast ball valve can be remotely controlled; the flow further can be controlled, the fast ball valve is wide in application range, and the like.
Description
Technical field
The present invention relates to a kind of control ball valve, especially relate to a kind of convenient quick closing valve ball valve regulating flow.
Background technology
In on the pipeline of existing hydrogen supply valve station, original design have a temperature transmitter, effusion meter, pressure transmitter and quickly
Stop valve HV03.Effusion meter is used for monitoring actual flow；Temperature transmitter and pressure transmitter are used for monitoring client
On-the-spot actual line temperature and line pressure；Repid cut-off valve can be with quick closedown under accident conditions, such as hydrogen pipe
Line leakage, fracture etc.；But in actual applications, the pressure of curstomer's site is relatively low, when causing this valve to open,
Flow moment is more than 1000Nm3/h, and design discharge is only 20-200Nm3/h；Flow is uncontrollable, the most defeated
The hydrogen delivering to client cannot be settled accounts.
Chinese patent CN202418695U discloses a kind of flow scalable ball valve, and left valve barrel, right valve barrel form
Shell, connects with screw thread pair, and left valve barrel, pad, left valve seat, spheroid, right valve seat, right valve barrel are sequentially connected with,
Handle, gland, valve rod, filler, spheroid are sequentially connected with, and have a taper hole in the middle of spheroid, and left end aperture is big,
Equal with left valve seat endoporus, right-hand member aperture is little, and less than the endoporus of right valve seat, left and right valve seat endoporus is equal, right valve
Seat is downstream valve seat, makes by nonmetallic materials, and left valve seat is that metal material is made, due to the taper hole in the middle of spheroid
Structure, as long as at the edge of taper hole right output port in the pore diameter range of right valve seat, had both reached the purpose of regulating flow quantity,
Also will not wash away the sealing surface of downstream valve seat, although this ball valve can increase the service life, but still cannot solve
Flow rate calculation problem when changes in flow rate is bigger.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of and realize remotely control
System, flow can realize the convenient quick closing valve ball valve regulating flow controlled, range of application is wider.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of convenient quick closing valve ball valve regulating flow, including spool, controls cylinder and localizer, and this localizer is pacified
Being contained on control cylinder, be connected with control cylinder by instrument airduct, the lower section of localizer is provided with and is connected with spool
Valve position feedback device, this feedback device is connected with fixture signal.Installation positioner on ball valve, thus real
The most remotely operate.
Connecting on described localizer and have double acting module, this double acting module is by two instrument airducts and control gas
Cylinder connects.
Described double acting module controls the localizer duty of two states, valve when closing and open bigger
When closed the most slowly, when 0% aperture, being likely to result in and cannot completely close, valve has internal leakage,
The double acting module of employing is fine must solve this technical problem.
The connection of described localizer located device mounting bracket is arranged on control cylinder.
Described valve position feedback device is arranged in localizer mounting bracket.
Compared with prior art, the invention have the advantages that
1, owing to adding connector and localizer, it is possible to achieve the aperture of Remote control valve door.
2, flow can realize controlling, and controls minimum discharge at 50Nm3/ h, maximum stream flow is at 1000Nm3/ h,
Thus range of application is the widest.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure, 1-spool, 2-control cylinder, 3-localizer, 4-double acting module, 5-instrument airduct, 6-valve
Position feedback device, 7-localizer mounting bracket.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
A kind of convenient quick closing valve ball valve regulating flow, its structure is as it is shown in figure 1, include spool 1, control cylinder 2
And localizer 3, this localizer 3 is arranged on control cylinder 2, is connected with controlling cylinder 2 by instrument airduct 5
Connecing, specifically, localizer 3 connects and has double acting module 4, this double acting module 4 is by two instrument wind
Pipe 5 is connected with control cylinder 2 respectively.Double acting module 4 is utilized to control localizer 3 when closing and open bigger
The duty of two states, when closed the most slowly, when 0% aperture, being likely to result in cannot be complete for valve
Contract fully, valve has internal leakage, and the double acting module 4 of employing is fine must solve this technical problem.
The lower section of localizer 3 is provided with the valve position feedback device 6 being connected with spool 1, this feedback device and location
Device 3 signal connects, so that localizer 3 can the keying of precision control valve door.The located device of localizer 3 is installed
Support 7 connection is arranged on control cylinder 2.Valve position feedback device 6 is arranged on localizer mounting bracket 7
In.The present invention is by installation positioner 1 on ball valve, thus realizes remotely operation.And the localizer 3 used
Flow can be controlled, control minimum discharge at 50Nm3/ h, maximum stream flow is at 1000Nm3/ h, thus should
The widest by scope.
