Abstract
The utility model belongs to the technical field of engineering mechanical equipment, and particularly discloses a lock globe valve used for an engineering mechanical fuel pipeline, which aims to prevent fuel in an engineering mechanical fuel tank from being lost. The utility model adopts the technical scheme that the lock globe valve comprises a valve body, a valve core, a lock core and a key, wherein the inner cavity of the valve body is a three-way pipeline, and the two horizontally connected pipelines of the three-way pipeline which are provided with spiral openings at the two ends are connected with a fuel drain pipe; the valve core is arranged at the center of the inner cavity of the valve body; the valve core is tightly matched with the pipelines on the two sides, so as to form a closed or open circuit; the lock core is arranged at the upper part of the valve core and integrated with the valve core; and the lock core is mounted in the vertical pipeline of the three-way pipeline taken as the inner cavity of the valve body. By mounting the lock globe valve on the fuel drain pipeline of the engineering mechanical fuel tank, as the fuel drain pipeline can only be opened through the key, the problem that the fuel is easy to be lost as the engineering machinery works and parks on the field is effectively avoided, so as to reduce unnecessary economical loss for users. The lock globe valve used for the engineering mechanical fuel pipeline has simple and compact structure and popularization and application value, and is convenient to mount on the engineering machinery.
Description
Technical field
The utility model relates to a kind of locking and opening device of engineering machinery fuel pipe, belongs to the engineering mechanical device technical field.
Background technique
The pipeline great majority of draining the oil of present known engineering machinery fuel tank are not installed locking formula pipe valve device; And its opening ways of minority installation locking pipe valve device is not unique; Often can use other instrument and open pipe valve, the oil plant in the fuel tank is not had protective action.Because how engineering machinery is worked in the open air and parked, the oil plant in the fuel tank very easily by lawless person's theft or loss, can cause very big economic loss to the user like this.Therefore, be necessary to design and develop a kind of locking formula pipe valve device that is used for the pipeline of draining the oil of engineering machinery fuel tank, lose to prevent fuel tank oil plant accident effectively.
The model utility content
The utility model technical problem to be solved provides a kind of locking formula ball valve that is used for the engineering machinery fuel pipe that can avoid the interior oil plant of engineering machinery fuel tank to lose.
The technological scheme that solves the problems of the technologies described above is:
A kind of locking formula ball valve that is used for the engineering machinery fuel pipe, it is made up of valve body, spool, lock core, key, and body cavity is a triplate line; Two pipeline two ends that laterally connect of triplate line have the spiral mouth to be connected with drain line with the fuel oil casing respectively, and spool is at the center of body cavity, and the pipeline of spool and both sides closely cooperates; Form closed and the unlatching path; Lock core connects as one with spool on the top of spool, and lock core is installed in the vertical duct of triplate line of valve body cavity.
The above-mentioned locking formula ball valve that is used for the engineering machinery fuel pipe, the outer end of the vertical duct of the triplate line of said valve body is equipped with protective cover, and protective cover covers the upper surface of lock core, and protective cover is removable the connection with valve body.
The beneficial effect of the utility model is:
The fuel tank that this locking formula ball valve is installed in engineering machinery is drained the oil on the pipeline; Must could open the pipeline of draining the oil with key; Therefore can avoid engineering machinery owing to working and parking the problem that causes fuel oil to be lost effectively in the open air, reduce unnecessary economic loss to the user.The utility model is simple in structure, compact, easy for installation on engineering machinery, and popularizing value is arranged.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the schematic appearance of the utility model;
Fig. 3 is the mounting point schematic representation of the utility model.
Mark is following among the figure: valve body 1, protective cover 2, spool 3, lock core 4, key 5, fuel oil casing 6, drain line 7, return tube 8, oil inlet pipe 9.
Embodiment
Show among the figure that the utility model is made up of valve body 1, spool 3, lock core 4, key 5.Valve body 1 inner chamber is a triplate line; Spool 3 is installed in the center of valve body 1 inner chamber; The pipeline of spool 3 both sides has the spiral mouth to be connected with drain line 7, and spool 3 is formed closed with the pipeline of both sides and opened path, can make oil plant pass through spool 3 and flow out through drain line 7; Also can close spool 3 and cut off drain line 7, prevent that oil plant from flowing out.
Show among the figure, for unlatching and the closure of controlling spool 3, in the upper end of spool 3 lock core 4 has been installed, lock core 4 connects as one with spool 3, is installed in the vertical duct of triplate line of valve body 1 cavity.When inserting the direction rotation of key 5 to regulation, spool 3 is the and then direction rotation of key 5 rotations also, can realize the unlatching and the closure of ball valve, and position shown in Figure 1 is the closed state of spool 3.Engineering machinery is worked when parking in the open air, can key 5 be placed into safe position, the unlatching drain line 7 beyond can preventing to expect.
Show among the figure that in the outer end of valve body 1 protective cover 2 is installed, protective cover 2 can rotate, extract key 5 after, can protective cover 2 be rotated to the position coaxial with lock core 4, can the protection key keyhole.
Show among the figure that the valve body 1 of this locking formula ball valve is connected with fuel oil casing 6 through plug screw, joint, drain line 7 is connected with valve body 1, and oil inlet pipe 9 and return tube 8 connect with the advancing of motor, return opening respectively.As in case of necessity, the fuel oil of fuel oil casing 6 can be released through drain line 7 through opening valve body 1.
