Above-mentioned adaptor body can be the adaptor body of PVC high-density plastic's materials.
Above-mentioned spigot joint can be sealed active connected head.
The outer diameter of the internal thread in the above-mentioned wide footpath mouthful of screw thread can be 38 millimeters, and screw pitch is 1.5 millimeters, and the length of screw thread is 10 millis
Rice；The outer diameter of the internal thread in the narrow footpath mouthful 3 of screw thread is 28 millimeters, and screw pitch is 1.5 millimeters, and the length of screw thread is 20 millimeters.
The diameter of above-mentioned ventilating microhole can be 0.5 millimeter to 1.5 millimeters.
The utility model reasonable and compact in structure, it is easy to use；When hydrogen sulfide gas is demarcated, pass through adaptor body button
It is connect in sensor outside gas nozzle and forms the appearance gas calibration chamber of a relative closure, hydrogen sulfide gas is in the gas concentration of calibration intracavitary
Rise soon, response is rapid, improves measurement efficiency；And gas concentration is high, and the accuracy value of calibration is high；Sealing effect is good, avoids letting out
Dew, reduces to endangering employee's health；Installation operation is simple and convenient, is more convenient for promoting and applying；Adaptor body can fit simultaneously
Lead to series sensor for moral health series or Green, it is versatile.
Description of the drawings
Attached drawing 1 is the main view schematic cross-sectional view of the best embodiment of the utility model.
Coding in attached drawing is respectively：1 is adaptor body, and 2 be the wide footpath mouthful of screw thread, and 3 be the narrow footpath mouth of screw thread, and 4 be intubation
Connector, 5 be ventilating microhole.
Specific embodiment
The utility model, can technical solution according to the present utility model and actual conditions from the limitation of following embodiments
Determine specific embodiment.
In the utility model, for ease of description, the description of the relative position relation of each component is according to specification
The Butut mode of attached drawing 1 is described, such as：The position relationship of upper and lower, left and right etc. is the Butut according to Figure of description 1
Direction is come definite.
The utility model is further described with reference to embodiment and attached drawing：
As shown in Figure 1, double step double thread hydrogen sulfide sensor calibration adapter includes adaptor body 1；Adaptation
The right end of device body 1 is equipped in left narrow right wide stepped double thread opening, including the wide footpath mouthful 2 of screw thread and the narrow footpath mouthful 3 of screw thread；It is suitable
The left end closing of orchestration body 1, and the spigot joint connected with 1 inner cavity of adaptor body is fixed in 1 left end of adaptor body
4；It is equipped on the lateral wall of the adaptor body 1 in 3 left side of the narrow footpath of screw thread mouthful and at least one to be communicated with 1 inner cavity of adaptor body
Ventilating microhole 5.Wherein, the double thread opening of adaptor body 1 can be suitable for moral health series sensor simultaneously and Green leads to series
Sensor, moral health series sensor are led to series sensor with Green and are produced for presently the most common two big serial gas sensors
Product；Moral health series sensor with Green lead to series sensor as all there are one connect gas nozzle；In use, it is damaged to avoid connecing gas nozzle
And sealing effect is destroyed, moral health series sensor is led to series sensor with Green and is being connect at gas nozzle through external screw thread equipped with protection
Cap；This adapter is exactly using the head protector external screw thread, and the mode being connected through a screw thread can be by adaptor body 1 and sensor
Between realize be tightly connected；Wherein, the wide footpath mouthful 2 of screw thread is according to the head protector external thread diameter size in moral health series sensor
Demand Design, the narrow footpath mouthful 3 of screw thread is that the head protector external thread diameter size requirements led to according to Green in series sensor design
's；In use, adaptor body 1 need to be only threaded at head protector external screw thread, the outer spiral shell of head protector of adaptor body 1 and sensor
Line is tightly connected and is buckled in sensor and connects outside gas nozzle, and forms the appearance gas calibration chamber of a relative closure（Ventilating microhole 5 is used to put down
Weigh pressure, is extremely small hole, can be neglected in calibration）；And the other end of adaptor body 1 then passes through spigot joint
4 are connected with the sample bottle of hydrogen sulfide gas, and the appearance gas calibration intracavitary that hydrogen sulfide gas enters adapter through pipeline is demarcated；Due to
Hold the small of gas calibration chamber, hydrogen sulfide gas rises soon in the gas concentration of calibration intracavitary, and response is rapid, improves measurement and imitates
Rate；And gas concentration is high, and the accuracy value of calibration is high；Sealing effect is good, avoids revealing, and reduces to endangering employee's health；
Calibration and the method for inspection of transmission are changed by this adapter, hydrogen sulfide gas has more been saved, has reduced consuming cost；Together
When, installation operation is simple and convenient, is more convenient for promoting and applying.
Can further optimization be made to above-mentioned double step double thread hydrogen sulfide sensor calibration adapter according to actual needs
Or/and it improves：
As needed, adaptor body 1 is the adaptor body of PVC high-density plastic's materials.PVC high-density plastic's materials
