Abstract
The utility model relates to a sealing head used for barrel liner leak detection, which belongs to the technical field of detection. The sealing head is to solve the technical problems that the prior sealing head has poor sealing effect, so the barrel liner is easy to be pressed and deform. The sealing head comprises a main body and a sealing ring arranged on the main body; the sealing head is characterized in that the sealing ring is a round of rubber bladder; the main body is provided with a sealing head inflation air duct which is communicated with an inflation cavity in the rubber bladder and a barrel liner inflation air duct directly communicated with the bottom of the sealing head; the sealing head inflation air duct and the air inlet of the barrel liner inflation air duct are arranged on the upper end of the sealing head. The sealing head used for barrel liner leak detection has good sealing effect, and the barrel liner is not easy to be pressed and deform.
Description
Technical field
The utility model relates to detection technique, particularly relates to a kind of technology that is used for the seal head of a barrel courage (as the bucket courage of the solar water heater water receiver) equipment that leaks hunting.
Background technology
Sun power with its cleaning, continually, safety etc. significant advantage, become countries in the world focus development resource.In the development of solar energy industry, solar water heater is the facility of quality of life of affecting the livelihood of every family, and it can utilize sun power that normal-temperature water is heated under the condition of consumption costs not.Therefore solar water heater is very practical and the family life facility of environmental protection.
Water receiver bucket courage is to be made through operations such as sheet metal operation, welding by stainless sheet steel in the solar water heater, and the check of leaking hunting is the once functional examination to above-mentioned fabricating quality.The structure of bucket courage as shown in Figure 5, what is called is leaked hunting and exactly the round 10 (being generally 12-36 hole) on the Manufactured bucket courage 9 is sealed with plug earlier, injecting compressed air in bucket courage 9 again, placing tank to overflow in whole bucket courage 9 does not then have, seeing its each commissure has and does not emit bubble, to show that measuring it does not have and leak.
Existing seal head as shown in Figure 6, form by conical body and " O " shape O-ring seal 12 that is sheathed on the conical body, seal head inserts back in the hole 10 of bucket courage under the acting in conjunction of inflation tension, makes the side face of " O " shape O- ring seal 12 and 10 edges, hole realize that applying seals in adding the downforce that is held on the seal head and bucket courage 9.Because it is long-pending less that this O-ring seal participates in the sticking part plane of sealing, and O-ring seal meeting torsional deformation when pressurized, being easy to occur the slit, its sealing effectiveness is relatively poor, can influence the check of leaking hunting.Therefore, a lot of seal heads employings thin slice shape O-ring seal 13 is as shown in Figure 7 arranged at present to improve sealing effectiveness, the sticking part plane that this O-ring seal participates in sealing is long-pending bigger, improved sealing effectiveness, it is not tight that but this O-ring seal can be fitted during 10 edge out-of-flatnesses in the hole, thereby influence sealing effectiveness.Above-mentioned two kinds of sealing means, in order to improve sealing effectiveness, it is tightr to make that O-ring seal can be fitted, and all needs seal head is applied big downforce in bucket courage radial direction, makes a barrel courage compressive deformation easily.
The utility model content
At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provides a kind of good sealing effect, and does not need seal head is applied external force, thereby can not cause the seal head that barrel courage leaks hunting that is used for of barrel courage compressive deformation.
In order to solve the problems of the technologies described above, a kind of seal head that barrel courage leaks hunting that is used for provided by the utility model comprises the seal head body and is sheathed on O-ring seal on the seal head body, it is characterized in that: described O-ring seal is one to be provided with the rubber pocket of inflatable chamber; Described seal head body is provided with the seal head inflation air flue that is communicated with the inflatable chamber in the rubber pocket, and the air intake opening of seal head inflation air flue is located at seal head body upper end.
Further, also be provided with the bucket courage inflation air flue of straight-through seal head body bottom on the described seal head body, the air intake opening of bucket courage inflation air flue is located at seal head body upper end.
Further, described seal head body comprises active body, establish with the air flue ring of active body upper end, be located at the guiding awl of active body lower end, described rubber pocket is sheathed on guiding awl top, and the air intake opening of described seal head inflation air flue and bucket courage inflation air flue is located on the air flue ring.
Further, described active body upper end is provided with the hanging handle that is used to connect the seal head control lever, and described hanging handle is provided with connecting hole.
The utility model provides is used for the seal head that barrel courage leaks hunting, because after the rubber balloon on the seal head that inserts each hole is inflated, respectively each hole is produced radial force, sealing is realized, so can adapt to the hole of different shape in each hole of tensioner, also very firm to the sealing of irregular hole, and each hole does not need seal head is applied external force, so can not cause a barrel courage compressive deformation when sealed yet yet on the bucket courage.
