Abstract
The utility model relates to a kind of adjust flux quick closing valve ball valve, comprise spool, control cylinder, positioning work piece, this positioning work piece is arranged on control cylinder, be connected with control cylinder by instrument airduct, the below of positioning work piece is provided with the valve position feedback device be connected with spool, and this feedback means is connected with fixture signal.Compared with prior art, the utility model can realize telecontrol and can control flow, also has the advantages such as application area is wider.
Description
Technical field
The utility model relates to a kind of control ball valve, especially relates to a kind of adjust flux quick closing valve ball valve.
Background technique
Existing hydrogen supply valve station pipeline is upper, is formerly designed with temperature transmitter, flowmeter, pressure transmitter and repid cut-off valve HV03.Flowmeter is for monitoring actual flow; Temperature transmitter and pressure transmitter are for monitoring the actual line temperature of curstomer's site and line pressure; Repid cut-off valve can quick closedown under accident conditions, as hydrogen gas lines leakage, fracture etc.; But in actual applications, the pressure of curstomer's site is lower, when causing this valve open, flow is instantaneously more than 1000Nm3/h, and design discharge is only 20-200Nm3/h; Flow is uncontrollable, and the hydrogen being delivered to client in a large number cannot be settled accounts.
Chinese patent CN202418695U discloses the adjustable ball valve of a kind of flow, left valve barrel, right valve barrel composition shell, connect with screw pair, left valve barrel, pad, left valve seat, spheroid, right valve seat, right valve barrel connects successively, handle, Gland, valve rod, filler, spheroid connects successively, a taper hole is had in the middle of spheroid, left end aperture is large, equal with left valve seat endoporus, right-hand member aperture is little, be less than the endoporus of right valve seat, left, right valve seat endoporus is equal, right valve seat is downstream valve seat, make by nonmetallic material, left valve seat is that metallic material is made, due to the taper hole structure in the middle of spheroid, as long as at the edge of taper hole right output port in the pore diameter range of right valve seat, both the object of regulating flow quantity had been reached, also the sealing surface of downstream valve seat can not be washed away, although this ball valve can increase the service life, but still cannot solve changes in flow rate larger time flow rate calculation problem.
Model utility content
The purpose of this utility model be exactly provide a kind of realize telecontrol to overcome defect that above-mentioned prior art exists, flow can realize the adjust flux quick closing valve ball valve that controls, application area is wider.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of adjust flux quick closing valve ball valve, comprise spool, control cylinder and positioning work piece, this positioning work piece is arranged on control cylinder, is connected with control cylinder by instrument airduct, the below of positioning work piece is provided with the valve position feedback device be connected with spool, and this feedback means is connected with fixture signal.Installation positioner on ball valve, thus realize remote operation.
Described positioning work piece is connected with double-action module, this double-action module is connected with control cylinder by two instrument airducts.
Described double-action module controls the working state of positioning work piece two states when closing and open larger, valve is relatively slower when closing, and when 0% aperture, may cause and cannot close completely, valve has internal leakage, and the double-action module of employing is fine must solve this technical problem.
Described positioning work piece is mounted on control cylinder through positioning work piece mounting bracket.
Described valve position feedback device is arranged in positioning work piece mounting bracket.
Compared with prior art, the utility model has the following advantages:
1, owing to adding link and positioning work piece, the aperture of telecontrol valve can be realized.
2, flow can realize controlling, and controls minimum discharge at 50Nm
3/ h, peak rate of flow is at 1000Nm
3/ h, thus application area is also wider.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-spool, 2-control cylinder, 3-positioning work piece, 4-double-action module, 5-instrument airduct, 6-valve position feedback device, 7-positioning work piece mounting bracket.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
A kind of adjust flux quick closing valve ball valve, its structure as shown in Figure 1, comprise spool 1, control cylinder 2 and positioning work piece 3, this positioning work piece 3 is arranged on control cylinder 2, be connected with control cylinder 2 by instrument airduct 5, specifically, positioning work piece 3 is connected with double-action module 4, this double-action module 4 is connected with control cylinder 2 respectively by two instrument airducts 5.Double-action module 4 is utilized to control the working state of positioning work piece 3 two states when closing and open larger, valve is relatively slower when closing, and when 0% aperture, may cause and cannot close completely, valve has internal leakage, and the double-action module 4 of employing is fine must solve this technical problem.
The below of positioning work piece 3 is provided with the valve position feedback device 6 be connected with spool 1, and this feedback means is connected with positioning work piece 3 signal, thus makes positioning work piece 3 can the keying of precision control valve door.Positioning work piece 3 is mounted on control cylinder 2 through positioning work piece mounting bracket 7.Valve position feedback device 6 is arranged in positioning work piece mounting bracket 7.The utility model by installation positioner 1 on ball valve, thus realizes remote operation.And the positioning work piece 3 adopted can control flow, control minimum discharge at 50Nm
3/ h, peak rate of flow is at 1000Nm
3/ h, thus application area is also wider.
