Abstract
The utility model relates to a sealing structure of an explosionproof bunter of a valve electric device, which comprises a box cover and a bunter extending out of the box cover, wherein the other end of the bunter penetrates into the inner cavity of the electric device, a support is fixedly installed on the box cover of the inner cavity of the electric device, the bunter penetrates through the support, a return spring mounted on the bunter in the support in a penetrating manner, and a sealing component is installed between the bunter and the box cover. The sealing structure is characterized in that a gland is sleeved on the bunter outside the box cover, an annular sealing groove is processed in the internal section of the gland, and a seal ring is arranged in the sealing groove. According to the utility model, the sealing groove is processed in the additionally arranged gland, and the direct processing on the box cover is avoided, so that the processing difficulty is reduced from the processing view; and furthermore, the dimensional accuracy of processing on the gland is convenient to guarantee, so that the sealing property is improved, the service life is longer and the maintenance cost is lowered.
Description
Technical field
The utility model belongs to the electric valve technical field, particularly relates to the explosion-proof feeler lever sealing configuration of a kind of electric device for valve.
Background technique
The field control mechanism of electric device for valve is used for the on-the-spot electronic control of electric valve, accomplishes the on-the-spot electronic keying of electric valve through on-the-spot button and operates, and the scene of Electric actuator is generally crawl control.Field control is used for the debugging maintenance of electric valve more, or in case of emergency on-the-spot electronic opening/shutting valve, and the reliability of its work is very important.
The explosion-proof feeler lever mounting structure of known technology electric device for valve: mainly comprise the case cover, stretch out the feeler lever of case cover, the other end of feeler lever gos deep into the Electric actuator inner chamber; On Electric actuator inner chamber case cover, be installed with support, said feeler lever passes support, and in support, installs Returnning spring on the feeler lever; And the sealing component between feeler lever and the case cover; Promoting feeler lever can be to the inboard axial motion of case cover, and then touches the Electric actuator switch inside, unclamps the feeler lever spring and makes its position that affranchises automatically.Sealing in the said structure is general only at the external part suit flexible gland of feeler lever, through gland it is compressed then; The exterior edge face processing seal groove that is employed in the case cover that also has, equipped then gland is realized the sealing between feeler lever and the case cover.
The deficiency that exists in the known technology mainly is: because long outdoor use seal closure easy ageing is damaged; This part is damaged; Therefore the sealing effect of seal closure will soon reduce, and needs often to change to safeguard.For second kind of structure and since on the case cover processing seal groove difficulty bigger, and dimensional accuracy cannot say for sure the card, its sealing effect is relatively poor in use.The sealability of Electric actuator control box cover can exert an influence to its internal electric element, thereby relates to the operational safety of Electric actuator, so excellent sealing performance is the guarantee of electric device for valve operation.
Summary of the invention
The utility model provides a kind of simple in structure, easy to assembly, explosion-proof feeler lever sealing configuration of the reliable electric device for valve of sealability for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The explosion-proof feeler lever sealing configuration of a kind of electric device for valve comprises the case cover, stretches out the feeler lever of case cover; The other end of feeler lever gos deep into the Electric actuator inner chamber; On Electric actuator inner chamber case cover, be installed with support, said feeler lever passes support, and in support, is coated with Returnning spring on the feeler lever; Between feeler lever and the case cover sealing component is installed, it is characterized in that: section is processed with annular seal groove in the suit gland on the outside feeler lever of said case cover, said gland, is provided with seal ring in the seal groove.
The utility model can also adopt following technical measures:
The said through hole interior edge face that installs feeler lever be provided with and feeler lever between realize the annular seal groove of sealing seal ring being installed in the annular seal groove.
Said seal ring adopts the O RunddichtringO.
Advantage and the good effect that the utlity model has are: because the utility model adopts said structure, promptly on the gland that adds, process seal groove, avoid from the case cover, directly processing; Say from machining angle like this; Reduced difficulty of processing, and accurate to dimension is convenient to guarantee on gland, in order further to improve sealability; Also increase seal ring in case cover inboard, realize the effect of twice double seal.Therefore the utility model is compared with known technology and is had better sealability, and working life is longer, has also reduced maintenance cost simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, case cover; 2, feeler lever; 3, Electric actuator inner chamber; 4, support; 5, Returnning spring; 6, gland; 7, seal ring; 8, seal ring.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, the explosion-proof feeler lever sealing configuration of a kind of electric device for valve comprises case cover 1; Stretch out the feeler lever 2 of case cover, the other end of feeler lever gos deep into Electric actuator inner chamber 3, on 3 casees covers of Electric actuator inner chamber 1, is installed with support 4; Said feeler lever 2 passes support 4, and in support 4, is coated with Returnning spring 5 on the feeler lever 2, suit gland 6 on the outside feeler lever 2 of said case cover 1; Section is processed with annular seal groove in the said gland 6, is provided with seal ring 7 in the seal groove, and said seal ring adopts the O RunddichtringO.
In order further to improve sealability; The said through hole interior edge face that installs feeler lever 2 be provided with and feeler lever between realize the annular seal groove of sealing; Seal ring 8 is installed in the annular seal groove, and said seal ring adopts the O RunddichtringO, because the active force of Returnning spring; Guarantee the inner sealing of seal ring 8, reached the effect of case cover inside and outside dual sealing.
The utility model is employed on the gland that adds and processes seal groove; Avoid from the case cover, directly processing, say from machining angle like this, reduced difficulty of processing; And accurate to dimension is convenient to guarantee on gland; In order further to improve sealability, also increase seal ring in case cover inboard, realize the effect of twice double seal.Therefore the utility model is compared with known technology and is had better sealability, and working life is longer, has also reduced maintenance cost simultaneously.
