Abstract
The utility model discloses a waterproof structure of a gas sensor. The waterproof structure of the gas sensor comprises a detection head; a sealed middle connection sleeve is arranged on the outer circumference face of the detection head; the sealed middle connection sleeve is in fixedly threaded connection with the detection head; a sealing cushion is arranged between the sealed middle connection sleeve and the detection head; and a sealing ring, a waterproof membrane and a pressing cover are sequentially arranged above the top of the sealed middle connection sleeve. The pressing cover is fixed with the sealed middle connection sleeve through a screw, and the pressing cover is sealed with the sealed middle connection sleeve through the sealing ring. According to the waterproof structure of the gas sensor provided by the utility model, water does not enter a part of the gas sensor after the gas sensor which is additionally provided with the waterproof membrane is soaked into the water with the depth of 1 m and the lasting time is more than 48 hours; and the sensor cannot be damaged or lose efficiency in a water condition for a short period, so that the waterproof structure of the gas sensor is safer to use.
Description
Technical field
The utility model relates to inflammable gas and toxic gas Environmental security detection range, more particularly, relates to a kind of waterproof construction that is used for the sensor of inflammable gas and toxic gas detection.
Background technology
Major equipment is exactly a gas sensor in inflammable gas and the detection of toxic gas Environmental security, is the key that guarantees safety detection so guarantee the operate as normal of gas sensor.Prior art mainly is to adopt: particle type sintering metal cover or the stainless steel netted cover of gas sensor with an apertured protected, and this structure is though guaranteed the gas penetration potential of gas sensor; But the drawback that it is also arranged simultaneously; Promptly when this structure periphery had water, water also can enter into inside configuration, will cause gas sensor to damage like this; Lose its measuring ability, whole warning system was lost efficacy.
The utility model content
The utility model technical matters to be solved is: overcome the deficiency that exists in the prior art, a kind of waterproof construction of gas sensor of safety and reliability is provided.
The waterproof construction of the utility model gas sensor; Be achieved through following technical proposals, comprise detecting head, it is characterized in that; The sealing intermediate connecting sleeve is arranged at the detecting head outer peripheral face; Said sealing intermediate connecting sleeve is fixedly connected through screw thread with detecting head, between sealing intermediate connecting sleeve and the detecting head sealing gasket is set, and sealing intermediate connecting sleeve over top sets gradually O-ring seal, waterproof membrane and friction top.Friction top is fixed through screw and sealing intermediate connecting sleeve, seals through O-ring seal between them.
The utlity model has following beneficial effect:
1. add when gas sensor behind the waterproof membrane partly is submerged in 1 meter dark water and also can not intake, and the duration is more than 48 hours.Even have in the environment of water in the short time like this, sensor can not damage or lose efficacy yet, thereby it is safer that product is used.
2. for the bigger environment for use of aqueous vapor, also can guarantee gas sensor surrounding environment relatively dry, make and obtained guarantee in serviceable life of product.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
As shown in Figure 1; Sealing intermediate connecting sleeve 4 is arranged at detecting head 6 outer peripheral faces; Said sealing intermediate connecting sleeve is fixedly connected through screw thread with detecting head, between sealing intermediate connecting sleeve and the detecting head sealing gasket 5 is set, and sealing intermediate connecting sleeve over top sets gradually O-ring seal 3, waterproof membrane 2 and friction top 1; Friction top is fixed through screw and sealing intermediate connecting sleeve, seals through O-ring seal between them.
The utility model can improve the serviceable life of gas sensor, stops water to enter into the gas sensor space, thereby the blanket gas sensor when even if gas sensor drowns like this, can not damage yet.This structure uses more safe, and safer structure is provided for the design of Related product.
Embodiment recited above describes the utility model preferred implementation; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design philosophy; Common engineering technical personnel make the technical scheme of the utility model in this area various distortion and improvement all should belong to the protection domain of the utility model.
