Description
Technical field
The utility model relates to a kind of ball valve, specifically refers to a kind of unitary tape ball valve with lock with check function.
Background technique
Ball valve is one of conventional pipe fittings; It is a kind of control unit realizing pipeline fluid Flow-rate adjustment, commutation or break-in facility, its structure forms primarily of valve body, spheroid, seal ring, valve rod and drive unit, spheroid and seal ring is provided with in valve body, and have medium channel, described spheroid is the open-shut device of ball valve, it has passage, and it does revolution fortune around valve body vertical centre, thus realizes the opening and closing of valve body.The lower end of valve rod adopts being flexibly connected with flat side with spheroid, and spheroid can be driven to rotate.
The working state of the control media that valve is mainly used to, in some occasion, valve can not random switch, in order to prevent the misoperation of not operation personnel, therefore locking steady job state is required to these valves, to guarantee pipe-line system safety, thus occurred that Ball Valve With Lock is with meeting the market requirement.Early stage Ball Valve With Lock complex structure, it is that conventional lock construction is incorporated on ball valve: the valve body being arranged on ball valve by the common lock on door, coordinate with it in the valve rod making the dead bolt of lock extend into valve body thus realize locking ball valve, dead bolt is made to exit valve rod by this lock of key turns of outside, then valve rod is namely rotatable, then operates ball valve by valve actuator.And the structure that now common Ball Valve With Lock is commonly used as shown in Figure 1: locking plate 1 ' is plate armature, in the ball valve of this structure with lock, locking plate is directly locked on Gland, if the screw on dismounting Gland, so locking plate can be taken away together with Gland, at this moment just loses locking effect.
In addition, power in Cemented filling or plant running all derives from pump, generally all will be installed in series after pump a safety check and a ball valve for cutting off, two deck valve doors are installed and just higher requirement are proposed to installing space, also will be higher to installation specification, and directly affects the installation of valve site and normally to use.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provide a kind of mounting structure of lock to arrange rationally, removing the situation of Gland screw, also can not lose locking effect, and there is under not changing ball valve normal structure length the unitary tape ball valve with lock with check function of automatic braking function.
For achieving the above object, the technical solution of the utility model includes valve body, valve seat, spheroid, valve rod and Gland, described valve body is provided with valve flowing channel and is positioned at the valve pocket on valve flowing channel, described sphere installation is in valve pocket, described Gland is fixedly installed on valve body upper end, and described valve rod rotation is arranged in Gland, the lower end of this valve rod and spheroid link, the upper end of this valve rod passes Gland upper end and it is linkedly set with valve rod driving handle, the top of described Gland is provided with the locking plate coordinated with valve rod joint rotation, the avris of this locking plate is provided with the first lockhole, the upper end portion of described valve body is provided with two second lockholes corresponding with the first lockhole, these two second lockholes are aligned with the first lockhole respectively and are locked by padlock, and two the second lockholes align with the first lockhole respectively during locked position just in time with the standard-sized sheet of ball valve and full-shut position corresponding, on described valve body opposing spheres side valve flowing channel in be provided with check valve spool assembly, this mangetic core assembly includes non-return valve block, described valve flowing channel is provided with the Boilor check valve seat that be sealed and matched corresponding to non-return valve block.
Further setting is described check valve spool assembly is Bivalved check valve mangetic core assembly, this Bivalved check valve mangetic core assembly includes positioning plate, valve shaft and reduction torsion spring, described positioning plate is fixedly installed in fluid valve road, valve shaft is arranged on positioning plate, described non-return valve block includes two panels flap, this two panels flap relative symmetry and all connecting with valve shaft, the two is that rotary opening and closing action is done in axle center with valve shaft, described reduction torsion spring cover is arranged on valve shaft, and two presser feets of reduction torsion spring are positioned on two flaps of both sides respectively.
Further setting is that described valve body is fixed by the mutual Butt sealing of fastening screw screw bolt and nut by left valve barrel and right valve barrel.
The utility model has the advantages that and utilize locking plate to be locked on valve body by the pivotal position of valve rod, thus removing the situation of Gland screw, also locking effect can not be lost, in addition, the utility model, under the prerequisite not changing ball valve normal structure length, corresponding check valve spool assembly is provided with in valve flowing channel, make it have cut-out and automatic braking function, and overall space arranges compact, installation footprint is little simultaneously.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
