Abstract
A tool special for detaching and installing an intake valve and an exhaust valve of a natural gas compressor is applied to detach and install the intake valve and the exhaust valve of a compression cylinder of the reciprocating natural gas compressor. The tool is mainly composed of a handle, a connecting rod and an adaptor, wherein a screw hole perpendicular to a central line is arranged in the middle of the cylindrical handle; one end of the connecting rod is provided with outer threads and is perpendicularly fixed on the handle through the threads; and the other end of the connecting rod is provided with outer threads and is fixed with the adapter through the threads. The tool has the advantages of being capable of detaching and installing the intake valve and the exhaust valve of the natural gas compressor, enabling the intake valve and the exhaust valve to be parallelly moved out or installed in a valve cavity of the natural gas compressor, avoiding damage to a valve body and the valve cavity during installation and detachment of the valve body, thereby the installation and the assembly detachment are fast and convenient and labor intensity is reduced.
Description
Technical field
The utility model relates to the maintenance tool of machinery, and particularly oil gas field is with reciprocating type natural gas compressor compression cylinder inlet and outlet valve tool specially for attaching and detaching.
Background technique
Reciprocating type natural gas compressor is the capital equipment that associated gas, reservoir gas supercharging are carried.At present, employed compressor bank majority is secondary or three grades of compressions, and every grade all is provided with suction valve and outlet valve; Suction valve has two groups, outlet valve to have two groups, and suction valve commonly used and outlet valve have two kinds of Mushroom valve and diaphragm valves.Be to guarantee the unit smooth running, other maintenances of various level and overhaul essentially, and free-hand dismounting or installation are sunken to suction valve and outlet valve in the compression cylinder valve pocket, time-consuming, effort and easy damaged valve body.
The model utility content
The purpose of this utility model is: a kind of natural gas compressor air inlet and exhaust valve tool specially for attaching and detaching is provided, is used for disassemble or assemble natural gas compressor air inlet and exhaust valve, realize parallel shifting out or the air inlet and exhaust valve of packing into from the natural gas compressor valve pocket.
The technical solution adopted in the utility model is: natural gas compressor air inlet and exhaust valve tool specially for attaching and detaching, mainly form by handle, connecting rod and crossover sub, and the screw perpendicular to center line is arranged in the middle of the cylinder bodily form handle.One end of connecting rod has outside thread, and the threaded one end of connecting rod is vertically fixed on the handle; It is characterized in that: the other end at connecting rod has outside thread, and the threaded one end of connecting rod is fixed with crossover sub.
Described crossover sub is a cylinder shape, at the two ends of crossover sub internal thread is arranged respectively, and an end internal thread can be connected with connecting rod; The internal thread of the other end can be connected on the compression cylinder air inlet and exhaust valve valve body outside thread.On the outer wall of crossover sub, have one section be outside hexahedron.
For the internal thread of the compression cylinder air inlet and exhaust valve valve body end that adapts to different size, described crossover sub preparation has a plurality of, can change crossover sub with the specification of the internal thread of valve body end.
The beneficial effects of the utility model: the utility model natural gas compressor air inlet and exhaust valve tool specially for attaching and detaching, during dismounting inlet and outlet valve, instrument and valve are linked as an individuality by screw thread, behind the slight double swerve instrument, can be with its parallel shifting out from valve pocket; During installation, by screw thread instrument and valve are linked as an individuality equally, parallel immigration valve pocket, the assurance valve body is once sat flat, avoid reducing the technical difficulty of its operation greatly, owing to dismounting, installation process can not make valve body contact valve pocket because of valve body tilts to leak gas, and need not to re-use hammer or copper rod knocks valve body, promptly can not damage valve body and valve pocket.
Through on probation in the maintenance of 7 reciprocating natural gas compressor groups, avoided damaging in the valve body dismounting phenomenon of valve body and valve pocket fully, make disassembly process convenient and swift, reduced personnel labor.
