Abstract
The utility model discloses a level glass which includes an indicator, a bracket used for mounting the indicator, a glass lens and a lens body provided with a mounting hole and an upper seal slot; the upper seal slot is arranged at the end part of the mounting hole of the lens; the cavity wall of the lens mounting hole is provided with a lower seal slot; a seal ring is arranged in the lower seal slot; and the seal ring is arranged between the lens body and the lens for forming seal.
Description
Affiliated technical field
The utility model relates to and is applied to the refrigeration industry liquid-sighting glass.
Background technology
Liquid-sighting glass is parts in the refrigeration system loop, its inside has the indicator that can meet the water variable color, when the cold-producing medium in the system circuit contacts through liquid-sighting glass and with indicator, if the cold-producing medium water cut is too high, indicator meeting variable color, dangerous with prompt system.Because liquid-sighting glass is applied in the pressure system, its sealing is the key characteristic of this product.Product hermetically-sealed construction in the market is: in mirror body inside, eyeglass top processing seal groove 1`, polytetrafluoroethylene sealing gasket 3` is installed in groove, reducing is carried out on camera lens top, the mirror body is inwardly produced shrink, sealing gasket 3` is pressed on the glass mirror 2`, to reach the purpose of sealing.This kind mode is extremely wayward in process of production, and parameters such as necking force also is difficult for determining.Necking force is slightly little, poor sealing then, and product produces and leaks; Necking force is big slightly, the glass mirror of then can crushing.And compressing sealing means, teflon can not bear excessive pressure.
Summary of the invention
The utility model will solve the deficiency that prior art is difficult for assembling, processing, provides a kind of connection, sealing reliable, and is convenient to the liquid-sighting glass that assembles, process.
Liquid-sighting glass described in the utility model, comprise indicator, be used for support, the glass mirror of indicator installation and the mirror body of being with mounting hole and last seal groove, the described seal groove of going up is positioned at eyeglass mounting hole end, it is characterized in that: also have lower seal groove cavity on the chamber wall of eyeglass mounting hole, be provided with O-ring seal in the described lower seal groove cavity, O-ring seal forms sealing between mirror body and eyeglass.
Further, described going up in the seal groove is equipped with snap ring, and the inboard of described snap ring covers on the described eyeglass, the outside is covered by the upper limb of last seal groove.
Further, the upper surface of described eyeglass is provided with a back-up ring, and the upper limb of described back-up ring is lower than the described upper limb of going up seal groove.
Further, the chamber wall of the eyeglass mounting hole above the described eyeglass and the outside of described back-up ring have the screw thread that cooperatively interacts.
The O-ring seal of the corresponding specification of packing in the lower seal groove cavity of mirror body, the glass mirror of packing into is put into special tooling with product and carry out reducing on pressing machine, makes mirror body endoporus size suitable for reading less than lens dimension.After the reducing upper limb of mirror body groove prop up glass mirror above, reach the purpose that stops that eyeglass is deviate from.
The utility model has the advantages that: connect, seal reliably, and be convenient to assembling, processing.

Embodiment one
With reference to Fig. 2:
Liquid-sighting glass described in the utility model, comprise indicator, be used for support, the glass mirror 2 of indicator installation and the mirror body 6 of being with mounting hole and last seal groove, described upward seal groove 1 is positioned at the mounting hole end of eyeglass 2, also has lower seal groove cavity 5 on the chamber wall of eyeglass mounting hole, be provided with O-ring seal 4 in the described lower seal groove cavity 5, O-ring seal 4 forms sealing between mirror body 6 and eyeglass 2.
The O-ring seal of the corresponding specification of packing in the lower seal groove cavity of mirror body, the glass mirror of packing into is put into special tooling with product and carry out reducing on pressing machine, makes mirror body endoporus size suitable for reading less than lens dimension.After the reducing upper limb of mirror body groove prop up glass mirror above, reach the purpose that stops that eyeglass is deviate from.Empirical tests, size suitable for reading is an optimum dimension less than eyeglass 0.5-0.8mm.
The quantity of lower seal groove cavity can be more than one, can be according to the specific requirement setting.
Embodiment two
With reference to accompanying drawing 3:
Present embodiment and embodiment one difference are: described going up in the seal groove 1 is equipped with snap ring 7, and the inboard of described snap ring 7 covers on the described eyeglass 2, the outside is covered by the upper limb of last seal groove 1.
The O-ring seal of the corresponding specification of in the lower seal groove cavity of mirror body, packing into, the glass mirror of packing into, the snap ring of on the mirror body, packing in the seal groove then.Snap ring and card jail above the eyeglass reach the purpose that stops that eyeglass is deviate from.This kind mode is convenient installs, and is beneficial to repair and replacement when indicator lost efficacy again.
Embodiment three
With reference to accompanying drawing 4:
Present embodiment and embodiment one difference are: the upper surface of described eyeglass 2 is provided with a back-up ring 8, and the upper limb of described back-up ring 8 is lower than the described upper limb of going up seal groove 1.
The O-ring seal of the corresponding specification of in the lower seal groove cavity of mirror body, packing into, the glass mirror of packing into, the back-up ring of on the mirror body, packing in the seal groove then.With subsides jail above the eyeglass, by mirror body reducing card jail, reach the purpose that stops that eyeglass is deviate from above below the back-up ring.This kind mode is installed, and helps the application of necking down process, contacts with back-up ring after the reducing of mirror body, has avoided breaking because of misoperation causes eyeglass.
Embodiment four
With reference to accompanying drawing 5:
Present embodiment and embodiment four differences are: the chamber wall of the eyeglass mounting hole of described eyeglass 2 tops and the outside of described back-up ring 8 have the screw thread that cooperatively interacts.
Be processed with the internal thread of appropriate size at the openend of mirror body.The O-ring seal of the corresponding specification of packing in the lower seal groove cavity during assembling, the glass mirror of packing into, packing in mirror body upper end then is processed with and the mirror body externally threaded back-up ring that is complementary.By screwing, with below the back-up ring with paste the jail above the eyeglass, above with by mirror body reducing card jail, reach the purpose that stops that eyeglass is deviate from.Contact with back-up ring after the reducing of mirror body, avoided breaking because of misoperation causes eyeglass.
The described content of this instructions embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
