Abstract
The invention discloses a calibration cover. The calibration cover comprises a calibration cover main body. The calibration cover is characterized in that: the calibration cover main body is cylinder-shaped, an opening is formed at one side of the calibration cover main body, a concave structure is formed at the top part of the calibration cover main body, an air outlet hole, an air inlet hole and a center hole are formed at the bottom part of the calibration cover main body, the center hole is arranged at the center part of the bottom part of the calibration cover, the air inlet hole and the air outlet hole are arranged at two sides of the center hole, and the air outlet hole, the air inlet hole and the center hole are all through holes. The calibration cover has the beneficial effects that the calibration of the diffusion and pumping inspection equipment is realized, the structure is simple, the calibration air channel is reasonable, and air calibration is convenient.
Description
Technical field
The present invention relates to a kind of calibration mask, be specially a kind of calibration mask spreading double pump suction type detection equipment。
Background technology
At present, detect in environment electrical appliance equipment at damp, the application of gas detection equipment is increasingly extensive, complexity because of tested gaseous environment, the corresponding detection equipment used also constantly increases New function, instructions for use can not have been met at some environment for single diffusion type gas detection equipment, therefore the double pump suction type integrated gases detection equipment of diffusion has been increased newly, detection equipment is before putting into onsite application, the calibration being required for equipment being carried out detection numerical value by calibrating gas is demarcated, in traditional gas detecting detection equipment, the demarcation of diffusion type gas detection equipment is connected with gas piping by sensor lower cover can complete demarcation, but owing in holding concurrently pump suction type equipment integrally in diffusion, original sensor wrap bottom adds the pumping pipeline being connected with air pump, former demarcation mode cannot have been used to demarcate。
Summary of the invention
In order to overcome above-mentioned technical problem, the present invention provides a kind of calibration mask, holds concurrently in pump suction type one detection equipment calibration in diffusion, can be intercepted by pumping pipeline, equipment is demarcated。
This invention address that the technical scheme that the problems referred to above adopt is: a kind of calibration mask, including calibration mask main body, it is characterised in that: described calibration mask main body city is cylindrical, and in described calibration mask main body, side is provided with opening, and described calibration mask body top is provided with concave structure；Described calibration mask bottom part body is provided with steam vent, air inlet and centre bore；Described centre bore is positioned at place of calibration mask bottom centre, described air inlet and both sides, steam vent centrally disposed hole；Described have steam vent, air inlet and centre bore to be through hole。
Photography open slot in side on described centre bore, described open slot is corresponding with the opening in calibration mask main body, and described open slot is between air inlet and steam vent。
Calibration mask adopts nylon plastic(s) material, and its profile is cylinder, and inside is concave structure, and its concave structure matches with cover structure under sensor。Calibration mask center structure is circular hole, its size can pass through the joint of pumping pipeline terminal, between cylindrical wall, an open slot is designed at the circular hole with center, its width can pass through the steel pipe of pumping gas circuit, calibration mask centre bore extremely aligns with sensor center position through steel pipe through open slot, then upward sliding calibration mask makes to fixedly mount with cover structure under sensor。At one air inlet of bottom design and three steam vents of calibration mask, demarcate accurately to facilitate the calibrating gas entering calibration mask can constantly enter sensor。
The invention has the beneficial effects as follows: the calibration of the double pump suction type detection equipment of realization diffusion is demarcated, not only simple in construction, and demarcates gas circuit rationally, facilitates Demarcate Gas。

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described。
Detailed description of the invention one: a kind of calibration mask, including calibration mask main body (1), it is characterized in that: described calibration mask main body (1) city is cylindrical, the upper side of described calibration mask main body (1) is provided with opening, and described calibration mask main body (1) top is provided with concave structure (2)；Described calibration mask main body (1) bottom is provided with steam vent (4), air inlet (6) and centre bore (5)；Described centre bore (5) is positioned at place of calibration mask bottom centre, described air inlet (6) and steam vent (4) centrally disposed hole (5) both sides；Described have steam vent (4), air inlet (6) and centre bore (5) to be through hole。
Upper side photography open slot (3) of described centre bore (5), described open slot (3) is corresponding with the opening in calibration mask main body (1), and described open slot (3) is positioned between air inlet (6) and steam vent (4)。
Detailed description of the invention two:
As it is shown in figure 1, described perspective view of the present invention includes: calibration mask main body (1), concave structure (2), open slot (3), steam vent (4) and centre bore (5)。The profile of described main body (1) is cylinder, and described concave structure (2) is fixing with device sensor to be connected, and its shape is coincide with sensor lower cover。Described pumping plant steel pipe is alignd with centre bore (5) axle center by open slot (3)。Described steam vent (4) forms aerofluxus gas circuit with open slot (3)。
Detailed description of the invention three: as in figure 2 it is shown, described cross-section structure of the present invention includes: concave structure (2), steam vent (4), centre bore (5) and air inlet (6)。Described calibrating gas enters calibration mask by air inlet (6), is discharged by steam vent (4) after being fully contacted with sensor。
Claims (2)
1. a calibration mask, including calibration mask main body, it is characterised in that: described calibration mask main body city is cylindrical, and in described calibration mask main body, side is provided with opening, and described calibration mask body top is provided with concave structure；Described calibration mask bottom part body is provided with steam vent, air inlet and centre bore；Described centre bore is positioned at place of calibration mask bottom centre, described air inlet and both sides, steam vent centrally disposed hole；Described have steam vent, air inlet and centre bore to be through hole。
