Problems solved by technology

[0002] At present, in the actual production process of the oil field, the traditional stop valve is connected to the pressure gauge, and then connected to the adapter to control the pressure. In this way, the production cost is increased, the installation is cumbersome, and the labor intensity of the operators is increased. If If there is excess pressure, there will be hidden dangers of safety accidents when the pressure gauge is replaced; therefore, a combination of the conversion joint and the stop valve is designed, which can save costs in production, reduce the labor intensity of operators, and increase safety. It is a problem that both production and use units need to solve

Embodiment Construction

[0011] Attached below figure 1 , the specific embodiment of the present invention will be further described.

[0012] Such as figure 1 As shown, the valve needle 1 is threaded to the adapter body 8, and there are two ring grooves on the valve needle 1, which are used to place the O-ring 7 to enhance the sealing performance of the stop valve; one end of the adapter body 8 is processed into a taper External thread, the other external thread is the same type as the internal thread of shell cap 3; shell cap 3 is tightened on the adapter body 8 to prevent valve needle 1 from leaving the adapter body 8, handwheel 5 is placed on valve needle 1, and nut 4 is tightened The valve needle 1 is used to fix the handwheel 5, the gasket 6 is placed between the handwheel 5 and the nut 4, and the valve needle 1 can be opened or closed by turning the handwheel 5; The opposite internal thread is used to place the valve needle 2 and connect the pressure gauge.

Abstract

The invention relates to an adapter capable of controlling pressure. A valve needle 1 is in threaded connection with an adapter body, and two annular grooves are formed in the valve needle 1 and used for containing O-shaped sealing rings to enhance the sealing performance of the adapter. One end of the adapter body is processed into a taper external thread, and an external thread at the other end and a shell cap internal thread are the same in model. A shell cap is screwed on the adapter body to prevent the valve needle 1 from leaving the adapter body, a hand wheel is placed on the valve needle 1, a nut screws the valve needle 1 to fix the hand wheel, and a gasket is placed between the hand wheel and the nut. Two opposite internal threads are designed on the same horizontal line of the adapter body and are used for containing a valve needle 2 and connecting a pressure gauge. The device has the advantages that a stop valve is machined on the adapter body, so that the adapter and the stop valve are combined, the production cost is saved, and the labor intensity of operators is relieved; and then the valve needle 1 and the valve needle 2 are opened or closed, so that the working state of the pressure gauge is controlled, and when the pressure gauge is replaced, the potential safety hazard is reduced, and the working efficiency and the economic benefit are improved.

Description

technical field [0001] The invention belongs to the field of petroleum machinery, in particular to a pressure-controllable conversion joint. Background technique [0002] At present, in the actual production process of the oil field, the traditional stop valve is connected to the pressure gauge, and then connected to the adapter to control the pressure. In this way, the production cost is increased, the installation is cumbersome, and the labor intensity of the operators is increased. If If there is excess pressure, there will be hidden dangers of safety accidents when the pressure gauge is replaced; therefore, a combination of the conversion joint and the stop valve is designed, which can save costs during production, reduce the labor intensity of the operators, and increase safety. It is a problem that both production and use units need to solve. Contents of the invention [0003] In order to realize the combination of the adapter and the shut-off valve, save the produc...
