Anti-blocking throttling valve

Abstract

The invention discloses an anti-blocking throttling valve. The anti-blocking throttling valve comprises a valve body, a second disc, micro motors, a first disc and baffles. The valve body comprises anoil feeding pipe and an oil outputting pipe, and the oil feeding pipe is vertically connected with the oil outputting pipe. The top end of the oil outputting pipe is fixedly provided with a pressingscrewed cover through bolts, the top end of the pressing screwed cover is connected with a pressing nut in a threaded manner, and the pressing nut is internally connected with a valve rod in a threaded manner. The second disc is fixedly installed in the middle of the oil outputting pipe, the bottom of the pressing screwed cover is fixedly provided with electric push rods, and the output ends of the electric push rods are fixedly provided with a power box. The micro motors are fixedly installed at the top end inside the power box through bolts, and the output ends of the micro motors are fixedly provided with rotating shafts through couplers. The valve rod penetrates through the power box to be connected with the first disc in a welded manner, the baffles are connected with the oil feedingpipe in a clamped manner, and the front surfaces of the first disc and the second disc are provided with a plurality of circular through holes. By means of the anti-blocking throttling valve, blockageof the throttling valve can be prevented.

Description

Technical field [0001] The invention relates to the field of valve bodies, in particular to an anti-blocking throttle valve. Background technique [0002] Throttle valve is an important part of Christmas tree equipment in the process of oil and gas transportation. It mainly controls oil and gas flow by changing the flow area of ​​the valve. [0003] At present, there are major defects in the throttle valve. The clogging of the throttle valve is a very common phenomenon. On the one hand, untreated crude oil contains large particles of impurities, which cause blockage when flowing through the orifice. On the other hand, the oil and gas viscosity is high. , Especially when the impurity content is large, the impurities in the oil accumulate and adhere to the vicinity of the orifice, causing blockage. Summary of the invention [0004] The purpose of the present invention is to provide an anti-blocking throttle valve to solve the above-mentioned background art problems. [0005] In order ...

Problems solved by technology

[0003] At present, there are major defects in the throttle valve. The blockage of the throttle valve is a very common phenomenon. On the one hand, untreated crude oil contains impurities with large particles, which cause blockage when it flows through the throttle hole; on the other hand, the viscosity of oil and gas is large. , especially when the impurity content is large, the impurities in the oil accumulate and stick near the orifice, causing blockage
