Abstract
The utility model discloses a gas examination cover is divided to diffusion formula combustible gas calibrating installation sealed, including the examination cover body, examination cover body lower extreme sets up the gas outlet, and the outlet duct is connected to the gas outlet, the gaseous hose of outlet duct connection, examination cover body upper end sets up rubber seal, and the alarm probe inserts the internal portion of examination cover by the rubber seal centre bore. The outlet duct is the outlet duct of the flexible rod -type of cavity. The internal portion of examination cover is contact chamber, a horizontal branch air sifter board of contact chamber. The internal wall of examination cover sets up multistage buckle, the edge card that divides the air sifter board is in the buckle. The utility model is suitable for a several kinds of common diffusion formula combustible gas detection alarm wares in the oil field to the degree of accuracy of quantity transmission when improving the examination, lowering apparatus response time provides technical support for effectively regularly tracing to the source of detection alarm ware.
Description
Technical field
The utility model relates to flammable gas-detecting alarm device Calibration Technology, and specifically diffusion type inflammable gas calibrating installation enclosure-type divides gas to examine and determine cover.
Background technology
At present in " JJG693-2011 flammable gas-detecting alarm device " vertification regulation, concrete regulation is not made to the pattern of flammable gas-detecting alarm device calibrating diffusion shell.In on-site proving process, verification worker generally uses that producer is equipped with or homemade calibrating to cover.
Calibrating cover existence 2 deficiencies of the instrument producer outfit of existing use: one is that the specification that the flammable gas-detecting alarm device produced due to different manufacturers is popped one's head in is not identical yet, also standard ununified in the industry, the calibrating cover that producer can only be used to be equipped with is examined and determine.Two is that the calibrating cover that is equipped with of most instrument manufacturer facility man not important technical indicator---do not design accordingly according to one of calibrating alarm in " JJG693-2011 flammable gas-detecting alarm device " by the response time, namely examine timing standard concentration gases and be pressed into alarm probe, shorten the response time of instrument, be not inconsistent with diffusion type flammable gas-detecting alarm device actual service conditions.
Utility model content
The purpose of this utility model is to provide diffusion type inflammable gas calibrating installation enclosure-type to divide gas to examine and determine cover, be applicable to the diffusion type flammable gas-detecting alarm device that oil field is several frequently seen, thus improve the accuracy of transmission of quantity value when examining and determine, the lowering apparatus response time, for effectively regularly tracing to the source of detection alarm device provides technical support.
In order to reach above-mentioned purpose, the utility model have employed following technical scheme, diffusion type inflammable gas calibrating installation enclosure-type divides gas to examine and determine cover, comprise calibrating cover body, described calibrating cover body lower end sets out gas port, and gas outlet connects escape pipe, and escape pipe connects air hose, described calibrating cover body upper end arranges rubber seal, and it is inner that alarm probe inserts calibrating cover body by rubber seal center pit.
Described escape pipe is the escape pipe of hollow Telescopic shaft type.
Described calibrating cover body inside is contact chamber, the horizontal point of air sifter plate of contact chamber.
Described calibrating cover body inwall arranges multistage buckle, and the edge card of described point of air sifter plate is in buckle.
Described point of air sifter plate is near gas outlet and be positioned at directly over gas outlet, and multiple through hole evenly offered by described point of air sifter plate.
Compared to prior art, the utility model has following beneficial effect:
First the utility model is connected with normal concentration gas tank body by normal concentration air hose, and gas flexible pipe is connected with hollow draw-tube.Normal concentration gas arrives gas outlet by expansion link, and after undue air sifter plate, normal concentration gas reaches desired concn fast in contact chamber, and evenly.Now normal concentration gas fully contacts with probe, completes the detection of inflammable gas.
Take full advantage of the diffusion of gas, reach rapidly demand concentration, improve calibrating accuracy, reduce the stochastic error of response time.
Different length probe can be adapted at multistage buckle diverse location by point air sifter plate.
Expansion link can be utilized can to detect the flammable gas alarm of higher position.
Technique is simple, dependable performance, convenient operating maintenance, transforms the demand that can meet the calibrating of other inflammable gas completely a little.
Accompanying drawing explanation
Fig. 1 is that diffusion type inflammable gas calibrating installation enclosure-type of the present utility model divides gas to examine and determine the structural representation of cover.
In figure: 1 is air hose; 2 is hollow Telescopic shaft type escape pipe; 3 is a point air sifter plate; 4 is calibrating cover body; 5 is rubber seal; 6 is contact chamber; 7 is multistage buckle; 8 is gas outlet.
Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the utility model.
As shown in Figure 1, diffusion type inflammable gas calibrating installation enclosure-type divides gas to examine and determine cover, comprise calibrating cover body 4, described calibrating cover body lower end sets out gas port 8, gas outlet connects escape pipe, escape pipe connects air hose 1, and described calibrating cover body upper end arranges rubber seal 5, and it is inner that alarm probe inserts calibrating cover body by rubber seal center pit.Described escape pipe is hollow Telescopic shaft type escape pipe 2.Described calibrating cover body inside is contact chamber 6, the horizontal point of air sifter plate 3 of contact chamber.Described calibrating cover body inwall arranges multistage buckle 7, and the edge card of described point of air sifter plate is in buckle.Described point of air sifter plate is near gas outlet and be positioned at directly over gas outlet, and multiple through hole evenly offered by described point of air sifter plate.
First normal concentration gas bottle be connected with air hose 1, air hose 1 is connected with hollow expansion link 2, and normal concentration gas enters into calibrating cover body 4 by air hose 1 and hollow expansion link 2.Air sifter plate 3 is divided to be stuck in the corresponding position of multistage buckle 7 according to the length of alarm probe.Normal concentration gas, after undue air sifter plate 3, is evenly distributed in calibrating cover body 4.Alarm probe enters into calibrating cover body 4 through rubber seal 5, and contacts with normal concentration gas and react, thus examines and determine.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
