Abstract
The utility model relates to a kind of CTA bin blanking valve of high safety, it is characterized in that: it comprises control valve (1), described control valve (1) comprises valve body (2), this valve body (2) is connected with valve rod (3), end and the actuator (4) of described valve rod (3) fix, the outer cover that described valve rod (3) is exposed to the part of valve body (2) has locking device (5), described locking device (5) is made up of fixed block (6) and locking lever (7), the end of locking lever (7) contacts with the valve rod (3) in longitudinal hole (6.1), the sidewall of described valve body (1) has two suction ports (8) and air outlet (9).The CTA bin blanking valve of this high safety can avoid process of stopping, and ensure that normally carrying out of production.
Description
Technical field
The utility model relates to a kind of CTA bin blanking valve of high safety.
Background technique
CTA(crude terephthalic acid) feed bin laying-off valve open or closed position time the retention time all long, because in CTA material, band is acid, after CTA material resting period in valve body is of a specified duration, valve body again switch time there will be heavy or cannot the phenomenon of switch, it is normally used and causes impact, cause its needs to stop repairing, the process once stop, the actuator that spool just can be made to be connected quits work, thus causes impact to production, thus reduces output.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one to avoid process of stopping, and ensures the CTA bin blanking valve producing the high safety normally carried out.
The purpose of this utility model is achieved in that
The CTA bin blanking valve of high safety of the present utility model, comprise control valve, described control valve comprises valve body, this valve body is connected with valve rod, end and the actuator of described valve rod fix, the outer cover that described valve rod is exposed to the part of valve body has locking device, described locking device is made up of fixed block and locking lever, longitudinal hole is had in the middle of described fixed block, described valve rod is fixed with actuator through after longitudinal hole, the side of described fixed block has horizontal blind hole, with internal thread in described horizontal blind hole, with outside thread in described locking lever, described locking lever is loaded in the horizontal blind hole of fixed block by internal and external threads cooperation, valve stem contacts in the end of locking lever and longitudinal hole, the sidewall of described valve body has two suction ports and air outlet.
Compared with prior art, the beneficial effects of the utility model are:
The CTA bin blanking valve of this high safety is by offering two suction ports and air outlet at the sidewall of valve body, CTA powder remaining in the gap between valve body and spool can be blown away in described suction port and air outlet, ensure valve body again switch time there will not be heavy or cannot the phenomenon of switch, ensure that the normal use of equipment; Simultaneously by arranging locking device on valve rod, and by the fixed block in locking device, valve body and actuator are kept apart, locking lever is housed in fixed block valve rod is fixed or unclamps, when valve repaired by needs, as long as fixed by valve rod by locking lever, valve rod just can not move, and so just just can place under repair to valve without the need to actuator being taken apart, avoid process of stopping, ensure that normally carrying out of production.
Accompanying drawing explanation
Fig. 1 is the structural representation of the CTA bin blanking valve of the utility model high safety.
Fig. 2 is the structural representation of fixed block in Fig. 1.
Wherein: valve body 1, spool 2, valve rod 3, actuator 4, locking device 5, fixed block 6, longitudinal hole 6.1, horizontal blind hole 6.2, locking lever 7, suction port 8, air outlet 9.
Embodiment
See Fig. 1 and Fig. 2, the utility model relates to a kind of CTA bin blanking valve of high safety, comprise control valve 1, described control valve 1 comprises valve body 2, this valve body 2 is connected with valve rod 3, end and the actuator 4 of described valve rod 3 fix, thus control actuator 4 moves back and forth, the outer cover that described valve rod 3 is exposed to the part of valve body 2 has locking device 5, described locking device 5 is made up of fixed block 6 and locking lever 7, longitudinal hole 6.1 is had in the middle of described fixed block 6, described valve rod 3 is through fixing with actuator 4 after longitudinal hole 6.1, the side of described fixed block 6 has horizontal blind hole 6.2, with internal thread in described horizontal blind hole 6.2, with outside thread in described locking lever 7, described locking lever 7 is loaded in the horizontal blind hole 6.2 of fixed block 6 by internal and external threads cooperation, the end of locking lever 7 contacts with the valve rod 3 in longitudinal hole 6.1.
The CTA bin blanking valve of this high safety by arranging locking device 5 on valve rod, and by the fixed block 6 in locking device 5, valve body 2 and actuator 4 are kept apart, locking lever 7 is housed in fixed block 6 valve rod 3 is fixed or unclamped, when valve repaired by needs, as long as fixed by valve rod 3 by locking lever 7, valve rod 3 just can not move, and so just just can place under repair to valve without the need to actuator 4 being taken apart, avoid process of stopping, ensure that normally carrying out of production.
The sidewall of described valve body 1 has two suction ports 8 and air outlet 9, described suction port 8 and air outlet 9 are for blowing away CTA powder remaining in the gap between valve body 1 and spool 2, ensure valve body 1 again switch time there will not be heavy or cannot the phenomenon of switch, ensure that the normal use of equipment.
