Embodiment Construction

[0038]It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0039] In this embodiment, the first direction refers to figure 1 in the A direction.

[0040] The valves in the prior art have the following main problems to realize the installation of test coupons:

[0041] 1. The valve only has a water inlet channel and an outlet channel. If you want to hang a piece, you must add a channel. The oil well vent-free anti-theft sampling valve whose publication number is CN201180541Y adds a sampling channel to the valve, and the oblique liquid outlet of the sampling channel can collect water samples, but this structure cannot fix the hanging piece and cannot meet the monitoring of corrosion and scaling.

[0042] 2. In order to truly reflect the corrosion and s...

Abstract

The invention provides a value device. The value device comprises a valve assembly and a hanging piece assembly; the valve assembly comprises a valve body and a valve core assembly, the valve body comprises a flow channel, an inlet and a first outlet, wherein the inlet and the first outlet communicate with the flow channel correspondingly, and the valve core assembly is movably arranged in the flow channel to block or open the inlet; the hanging piece assembly is detachably arranged in the flow channel, and one end of the hanging piece assembly penetrates through the first outlet; and when theinlet is in an open state, liquid flowing in through the inlet flows through the hanging piece assembly and then flows out. According to the value device, the problem of inconvenient installation ofa test hanging piece in the prior art is solved.

Description

technical field [0001] The invention relates to the field of oil exploitation, in particular to a valve device. Background technique [0002] Corrosion and scaling of oilfield production and transportation systems is an important problem in major oilfields, which seriously affects the normal production of oil wells. In order to realize the monitoring of pipeline corrosion and scaling, the method recommended in SY / T 5329 "Injection Water Quality Indicators and Analysis Methods for Clastic Reservoirs" is usually used to monitor pipeline corrosion and scaling. A test coupon is hung on the test pipe section on the pipeline, and the corrosion and scaling status of the pipeline is monitored by monitoring the corrosion and scaling status of the test coupon. This method is inconvenient to install. A test coupon is hung on the test pipe section on the water injection pipeline, and the original production pipeline needs to be cut and welded. During the process of cutting and welding ...
