Abstract
The utility model discloses a kind of three-way valve for instrument, this valve is formed primarily of main valve body, stop valve, plug and Decompression valves, and one end of main valve body has the outside thread connected with main pipeline, the other end to have the female instrumentation tap of tool, has passage in main valve body; The outside thread side of main valve body is screwed with the stop valve communicated with passage, and instrumentation tap side is screwed with the Decompression valves and the plug corresponding with Decompression valves that communicate with passage.Owing to being equipped with stop valve and Decompression valves on main valve body, close stop valve, after opening Decompression valves release, change instrument and just can't smell harmful peculiar smell, avoid personal injury; Back out plug when thinking the dirt in discharge route and get final product blowdown, twist plug place load onto corresponding instrument also can the instrument of verifying work whether accurately normal, avoid and pull down instrument and detect impact and produce normal operation.This three-way valve for instrument structure is simple, easy to use, can be widely used in the detection of ducted gas or liquid.
Description
One, technical field
The utility model relates to a kind of three-way valve for instrument instrument be switched on pipeline.
Two, background technique
Current, when people install instrument on various pipeline, generally all use throughway valve to be installed on pipeline as transition piece by instrument, adopt its deficiency one of throughway valve to be because nothing has pressure relief device, gas during replacing table in passage or liquid discharge can work the mischief to human body; Two must pull down from pipeline when being accuracys of detection table, and impact is produced and normally carried out; Three is without there being waste, can not the ducted dirt in expulsion valve place.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide one and has multi-functional three-way valve for instrument.
The technological scheme realizing the purpose of this utility model employing is: this valve is formed primarily of main valve body, stop valve, plug and Decompression valves, there is the outside thread connected with main pipeline one end of main valve body, the other end has the female instrumentation tap of tool, has passage in main valve body; The outside thread side of main valve body is screwed with the stop valve communicated with passage, and instrumentation tap side is screwed with the Decompression valves and the plug corresponding with Decompression valves that communicate with passage.
Described stop valve is made up of valve body, valve rod, cone valve, and valve rod is positioned at valve body, and the tail end activity of valve rod is equipped with cone valve, rotary valve rod, and cone valve can make pathway closure or conducting.
Described Decompression valves is made up of valve body, needle-valve, has discharge channel and pressure relief vent, be screwed with needle-valve in valve body in valve body.Rotating needle-valve can make discharge channel and pressure relief vent close or conducting.
This valve is loaded onto after instrument and main pipeline connect, and opens stop valve and pressure in pipe just can be shown.Close stop valve, replaceable instrument after opening Decompression valves release.Backing out plug can dirt in discharge route.
The beneficial effects of the utility model are: owing to being equipped with stop valve and Decompression valves on main valve body, close stop valve, after opening Decompression valves release, change instrument and just can't smell harmful peculiar smell, avoid personal injury, also can sample at Decompression valves place.Back out plug when thinking the dirt in discharge route and get final product blowdown, twist plug place load onto corresponding instrument also can the instrument of verifying work whether accurately normal, avoid and pull down instrument and detect impact and produce normal operation.This three-way valve for instrument structure is simple, easy to use, can be widely used in the detection of ducted gas or liquid.
Four, accompanying drawing explanation
Fig. 1 is the sectional structure chart of the utility model three-way valve for instrument.
Five, embodiment
In the accompanying drawings, the utility model three-way valve for instrument is formed primarily of main valve body, stop valve, plug and Decompression valves, and there is the outside thread 8 connected with main pipeline one end of main valve body 7, and the other end has the female instrumentation tap 1 of tool, has passage in main valve body 7; Described passage is by crosspassage 9,11 and vertical passage 10, and crosspassage 9 and vertical passage 10 communicate; Outside thread 8 side of main valve body 7 is screwed with the stop valve 3 communicated with passage 9, and instrumentation tap 1 side is screwed with and the Decompression valves 14 that passage 11 communicates and the plug 2 corresponding with Decompression valves 14.This three-way valve for instrument is loaded onto after instrument and main pipeline connect, and opens stop valve and pressure in pipe just can be shown.Close stop valve, replaceable instrument after opening Decompression valves release.Backing out plug can dirt in discharge route.Described stop valve 3 is made up of valve body 5, valve rod 4, cone valve 6, and valve rod 4 is positioned at valve body 5, and cone valve 6 is equipped with in the tail end activity of valve rod 5, and rotary valve rod cone valve can make passage 9 and passage 11 cut out or conducting.Its movable object of installing of tail end that described cone valve 6 is movably arranged on valve rod 5 is cone valve sealing channel 10 is sealed tighter.Described Decompression valves 14 is made up of valve body 15, needle-valve 13, has discharge channel 16 and pressure relief vent 12, be screwed with needle-valve 13 in valve body 15 in valve body 15.Rotate needle-valve 13 can make to close or conducting between discharge channel 16 and pressure relief vent 12.Stop valve 3 described in the present embodiment, Decompression valves 14 are arranged on the both sides of main valve body 7 respectively; But described stop valve 3 is arranged on arranging perpendicular to horizontal plane of main valve body 7 above, the lateral vertical that described Decompression valves 14 is arranged on main valve body 7 is arranged the most rationally in vertical surface, makes three-way valve for instrument profile more attractive in appearance, uses more convenient.
