Abstract
The utility model provides a double-articulated ball valve with a nut locking device. The double-articulated ball valve is firm in the position locking of articulated nuts and easy to install. The double-articulated ball valve comprises a valve body, a valve core, a handle for controlling the valve core, two articulated nuts and the nut locking device fixedly arranged on the valve body. Teeth are arranged on the circumferential edges on one sides of the articulated nuts close to the handle, and elastic clamping claws which the teeth can be clamped into are arranged on the sides of the nut locking device close to the articulated nuts. Even through the double-articulated ball valve is used under bad working conditions, such as vibration or thermal expansion, the locking device ensures that the articulated nuts can be firmly locked at the originally set positions, and water leakage is avoided. Locking parts are made of elastic materials, so that resetting is easy, and installation and overhaul are convenient.
Description
Technical field
The utility model belongs to the valve field.
Background technique
The nut of existing dual-active access valve all is to screw with feeling with hand, and tightness is different when screwing because of different people; In the course of time; Under various rugged environment, as under vibration or heat expansion state, and under the artificial careless situation; The valve nut situation that unscrews can occur and cause valve and valve joint not to press tightly, and can leak.
Summary of the invention
The technical problem that the utility model solves provides a kind of dual-active access valve firm, that be prone to the band nut locking device of installation that locks loose joint nut position.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of dual-active access valve with the nut locking device is provided; Comprise handle, two loose joint nuts of valve body, spool, control spool and be fixedly installed on the nut locking device on the valve body; Said loose joint nut has teeth at the circumferential edges near handle one side, and said nut locking device respectively has an elastic card claw that can snap in teeth near loose joint nut one side.
Further, said teeth are evenly distributed on the circumferential edges of loose joint nut.
Further, said nut locking device is a fusiformis.
Further, said elastic card claw is fixedly connected on the loose joint nut.
Compared with prior art; Beneficial effect is: the nut locking device through being installed on the valve body can guarantee the position that the loose joint fixed by nut at ball valve two ends is being set; Even under abominable operating conditions; Like vibration or thermal expansion, locking device can guarantee that still the loose joint nut is locked in former desired location securely, water leakage phenomenon can not occur; The Lock Part of the utility model adopts elastic material to process, and resets easily, and convenient the installation overhauled.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is a nut locking device structure schematic representation.
Embodiment
As depicted in figs. 1 and 2 is the utility model preferred embodiment; A kind of dual-active access valve with the nut locking device; Comprise handle, two loose joint nuts 1 of valve body 2, spool, control spool and be fixedly installed on the nut locking device 3 on the valve body; Said loose joint nut 1 has teeth at the circumferential edges near handle one side, and said nut locking device 3 respectively has an elastic card claw that can snap in teeth near loose joint nut one side.Teeth are evenly distributed on the circumferential edges of loose joint nut 1, and nut locking device 3 is a fusiformis, being fixedly connected on the loose joint nut 1 of elastic card claw.
The installation process of the utility model is following:
1), the inspection pipeline that will be connected with valve, guarantee that the two ends pipeline all has good coaxality (distortionless phenomenon), to avoid in the loose joint nut 1 screw thread place at mounted valve two ends formation mechanical stress.
2), screw off loose joint nut 1 and respectively with the two ends spiro cap on the pipeline that need connect separately.
3), two end connectors of valve and pipeline are separately linked together through alive being threaded.
4), nut locking device 3 is installed on the valve body, as shown in Figure 2.
5), valve is put between two valve joints, and, so just can lock loose joint nut 1 well with the tight nut of hand-screw.Unscrew loose joint nut 1 like need,, make it to break away from the teeth of loose joint nut, counterclockwise rotate loose joint nut 1 then just from two elastic card claws axially pressing the locking device both sides of valve, that's all.
Claims (4)
1. dual-active access valve with the nut locking device; Comprise handle, two loose joint nuts of valve body, spool, control spool and be fixedly installed on the nut locking device on the valve body; It is characterized in that; Said loose joint nut has teeth at the circumferential edges near handle one side, and said nut locking device respectively has an elastic card claw that can snap in teeth near loose joint nut one side.
2.
RootDual-active access valve according to the described band nut of claim 1 locking device is characterized in that said teeth are evenly distributed on the circumferential edges of loose joint nut.
3. the dual-active access valve of band nut locking device according to claim 1 is characterized in that, said nut locking device is a fusiformis.
4. the dual-active access valve of band nut locking device according to claim 1 is characterized in that, being fixedly connected on the loose joint nut of said elastic card claw.
