Abstract
The utility model discloses a few oily equipment pressure detection terminal ball valve of electric power, including keeping apart the ball valve, keep apart the one end of ball valve and pass through positive and negative silk adjusting nut connection terminal and connect, terminal joint and the few oily equipment sleeve pipe sample connection adaptation of electric power. The utility model discloses a switch position can require to adjust according to the customer, guarantees few oily equipment and sheathed tube safe operation.
Description
Technical Field
The utility model relates to a power transmission and distribution technical field especially relates to a few oily equipment pressure detection terminal ball valve of electric power.
Background
The electric power oil-less equipment pressure detection terminal ball valve is arranged at a sampling port of an oil-less equipment sleeve of a transformer substation, and at least an oil equipment detection unit is connected with a drainage tube so as to achieve the purposes of detecting the oil pressure of the sleeve and taking or supplementing oil to the sleeve. The valve switch position is required to be as horizontal as possible, upward, convenient to operate and maintain beautiful. The oil duct can be cut off when a power supply company overhauls or replaces the sleeve, and debugging and maintenance are facilitated.
Therefore, a ball valve is needed to close the oil passages of the body and the drainage tube to prevent the variable pressure oil from flowing out. The common ball valve has the advantages that the switch directions of the common ball valve are different when the common ball valve is installed with the oil-less equipment body at the same interval, the common ball valve is not attractive, the installation space of the terminal ball valve at the oil taking port of some sleeves is limited, and the possibility that the common ball valve cannot be installed exists.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an few oily equipment pressure detection terminal ball valve of electric power, its switch position can require to adjust according to the customer, can guarantee few oily equipment and sheathed tube safe operation.
In order to achieve the purpose, the utility model adopts the following technical proposal to realize:
the utility model discloses a few oily equipment pressure detection terminal ball valve of electric power, including keeping apart the ball valve, keep apart the one end of ball valve and pass through positive and negative silk adjusting nut connection terminal and connect, terminal joint and the little oily equipment sleeve pipe sample connection adaptation of electric power.
Preferably, the terminal connector and the positive and negative screw adjusting nut are matched by right-handed threads, and the isolating ball valve and the positive and negative screw adjusting nut are matched by left-handed threads.
Preferably, the end part of one end of the isolation ball valve is provided with a rubber ring sealing groove.
Furthermore, a sealing rubber ring is embedded in the rubber ring sealing groove.
Furthermore, the other end of the isolation ball valve is sleeved with an oil outlet joint.
Preferably, the isolating ball valve includes a cap.
The principle and the using method of the utility model are as follows: the direction adjusting nut (positive and negative screw adjusting nut) of the terminal joint is a left-right rotation positive and negative screw body, the joint of the terminal joint and the direction adjusting nut is a right-hand screw thread, the joint of the valve and the positive and negative screw adjusting nut is a left-hand screw thread, and the end face of the left-hand screw thread of the valve is provided with a rubber ring sealing groove, so that the sealing reliability is ensured. When the equipment, will turn into the terminal fitting with direction adjusting nut right-hand thread earlier, twist valve left-hand thread again and twist valve left-hand thread department, twist sleeve pipe sample connection department with the assembly at last, if the switch handle is not when the assigned position, the accessible is unscrewed direction adjusting nut, screws up the valve again and adjusts the switch position, ensures that the switch is in the operating position of being convenient for. After the installation, the valve rod is in a closed state of red to red, and the valve rod is in an open state of red to green. When the valve rod is rotated to place the valve core steel ball in a passage state, oil flows from an oil inlet of the terminal connector to an oil outlet of the valve and flows out; when the valve core steel ball is in a closed isolation state by rotating the valve rod, oil flows into the valve core steel ball through the oil inlet of the terminal connector and is stopped, and at the moment, the oil cannot flow out of the oil outlet of the isolation ball valve.
The switch position of the utility model can be adjusted according to the requirements of customers, and the safe operation of the oil-less equipment and the sleeve is ensured; and is beautiful and reliable.
The utility model discloses can the different sheathed tube less oily equipment of electric power of adaptation, use with drainage tube and detecting element cooperation.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses a few oily equipment pressure detection terminal ball valve of electric power, including keeping apart ball valve 4, keep apart the one end of ball valve 4 and pass through positive and negative silk adjusting nut 2 and connect terminal joint 1, terminal joint 1 and the little oily equipment sleeve pipe sample connection adaptation of electric power. Specifically, the method comprises the following steps:
the terminal fitting 1 is right-handed thread with the positive and negative screw adjusting nut 2, the isolation ball valve 4 is left-handed thread with the positive and negative screw adjusting nut 2, a rubber ring sealing groove is arranged at the end of one end of the isolation ball valve 4, and a sealing rubber ring is embedded in the rubber ring sealing groove. The other end of the isolation ball valve 4 is sleeved with an oil outlet joint, the isolation ball valve 4 is provided with a cover cap 3, and the terminal joint 1 is an M12 terminal joint.
Of course, the present invention may have other embodiments, and those skilled in the art may make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the appended claims.
