Two-dimensional primary and secondary compensation spray rotation steam pipe fast-switching device

Abstract

The invention discloses a two-dimensional primary and secondary compensation spray rotation steam pipe fast-switching device and belongs to the technical field of petrochemical equipment. The two-dimensional primary and secondary compensation spray rotation steam pipe fast-switching device comprises a first valve body. The first valve body is internally provided with a first valve rod, wherein thefirst valve rod is movably matched with the first valve body in a sealed manner. The rear portion of the first valve rod is provided with a first rear valve plate. A valve body cavity is divided intoa first valve cavity A and a first valve cavity B through the first rear valve plate. A second valve body of the same structure is arranged at the outer side of the first valve body in a matched manner. The device further comprises a reversing valve connected with the first valve body and the second valve body. The front end of the first valve rod is provided with a first valve disc. The first valve disc extends into a pipe cavity and is matched with or separated from a first pipe opening in a sealed manner. The two-dimensional primary and secondary compensation spray rotation steam pipe fast-switching device is provided with bidirectional parallel valves and achieves synchronous driving, and fluid in the pipe can be thoroughly intercepted; and the device is good in reliability, high in stability and safe and convenient to use. Under the combined action of a main valve element and a rotary push small valve, the labor intensity is remarkably lowered, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of petrochemical equipment, in particular to a two-dimensional primary and secondary compensation swirling steam pipe quick switch device. Background technique [0002] Solenoid valve with manual function is widely used in the control system of air, water, hot water, gas, diesel and other pipelines to control the flow or stop of fluid. When the valve needs to be opened, pull the handle hard, and the valve will open; when the valve needs to be closed, press the handle hard, and the valve will close. However, in the special field of petrochemical pipelines, due to the particularity of storing petroleum and gasoline, the use of solenoid valve switches has great potential safety hazards, so mechanical valves are generally used. However, the existing manual reversing valve is pulled manually, the frequency of pulling is high, the operation is tiring, and the work efficiency is low; and the spool of the existing ...

However, in the special field of petrochemical pipelines, due to the particularity of storing petroleum and gasoline, the use of solenoid valve switches has great potential safety hazards, so mechanical valves are generally used

However, the existing manual reversing valve is pulled manually, the frequency of pulling is high, the operation is tiring, and the work efficiency is low; and the spool of the existing manual reversing valve is reciprocating and cannot rotate, and the spool is easy to get stuck, which is obvious. Reduced work efficiency
