Double-end universal fast mounting instrument valve

Abstract

The invention discloses a double-end universal fast mounting instrument valve which is composed of an upper connection adjusting nut (1), an upper sealing ring (2), a valve body (3), a ball valve clack (4), a lower connection adjusting nut (5), a lower sealing ring (6) and operating handles (7). The double-end universal fast mounting instrument valve is characterized in that integrated type structural design is adopted, and the upper connection adjusting nut (1), the lower connection adjusting nut (5), the upper sealing ring (2), the lower sealing ring (6) and the like are integrated on the valve body (3). When butt joint is carried out on the threaded portion of an instrument and the instrument valve, sealing by thread seal tape is not needed, the connecting part can be adjusted in a universal mode, and thus the double-end universal fast mounting instrument valve is simpler and more convenient to mount. The problems that a common copper instrument valve needs to be sealed by the thread seal tape and is prone to leakage and difficult to adjust in direction are solved. Compared with the prior art, double-end loose joint inner threaded connection is adopted for the upper connection adjusting nut (1) and the lower connection adjusting nut (5), hard seal is adopted between the upper sealing ring (2) and a metal end face and between the lower sealing ring (6) and the metal end face, the thread seal tape does not need to be used any more, leakage is prevented thoroughly, directions of the valve body (3) and the instrument connected with the valve body (3) can be freely adjusted, and the instrument can be turned on and off and observed conveniently.

Description

1. Technical field [0001] The invention relates to an instrument overhaul valve, in particular to a device which is installed on a pipeline to connect an instrument and perform an overhaul function. 2. Background technology [0002] At present, the connection between the pipeline and the instrument in the prior art generally adopts a simple threaded valve connection. When tightening, it needs to be sealed with a raw material tape, which is troublesome and easy to leak. When installing the instrument, it is difficult to balance the direction of the operation handle and the surface of the instrument. If you want to adjust the direction, you need to remove the meter, re-wrap the raw material tape and reinstall it, which requires labor and materials. When the meter installation space is limited, the meter is difficult to rotate when tightened and cannot be installed. 3. Summary of the invention [0003] In view of the shortcomings of the above-mentioned existing technologies, the pres...
