Description
Technical field
The utility model relates to ocean engineering and Underwater Engineering field, is particularly useful for drawing of deep-sea analogue test pressure measuring cylinder holding wire, also is used for the drawing of holding wire of chemical industry equipment pressure vessel.
Background technology
In the test of simulated deep-sea environment; Testing equipment is the pressure measuring cylinder that can bear high pressure; When test specimen is put into pressure measuring cylinder and is made an experiment; Often have many holding wires to draw from pressure measuring cylinder inside, because the pressure ratio pressure measuring cylinder that bears in the pressure measuring cylinder is many greatly outward, drawing of holding wire has certain degree of difficulty.
In the prior art, adopt the ejector of watertight holding wire to carry out drawing of holding wire usually, dull and stereotyped through on the base of ejector, installing; On the said flat board rubber wick is installed; And utilizing cover plate to cover, said holding wire passes in flat board, rubber wick and the perforate of cover plate institute, through on the cover board applying extruding force successively; Make rubber wick be extruded distortion, thereby holding wire is sealed.The ejector of this watertight holding wire, because the effect of big pressure, rubber wick is prone to crimp, and directly contacts with the internal face of base, rubber wick usually can be stuck in base the inside of ejector, can't extract.
Also can adopt pouring procedure that signal cable is cast directly in the ejector, but this method need be changed ejector simultaneously when changing holding wire, troublesome poeration has increased labour intensity, and cost is high.
The utility model content
The applicant is to ejector troublesome poeration in the above-mentioned existing production technology, and shortcomings such as cost height provide a kind of rational in infrastructure; The ejector of easy to operate watertight holding wire; Thereby holding wire can be extracted in watertight connector easily, be difficult for stuckly, reduced cost.
The technical scheme that the utility model adopted is following:
A kind of ejector of watertight holding wire comprises base, rubber wick and cover plate, and its said base inside has multi-layer groove; Said ground floor bottom portion of groove is installed first sealing ring; On said first sealing ring backing plate is installed, said backing plate has leg, places rubber wick in the leg of said backing plate and pushes down through cover plate; Through second sealing ring nut is installed on the said cover plate, the excircle of said nut and base are opened second layer groove internal face and are connected; Said backing plate bottom has a plurality of fairleads, has a plurality of through holes that cooperate with it on the said rubber wick, has a plurality of fairleads that are used with fairlead and hole that rubber wick is opened on the said cover plate.
Its further technical scheme is:
Leave extruding allowance between said cover plate and the backing plate upper surface;
Said nut bottom is provided with step, and said step and base are opened between the internal face of second layer groove and left extruding allowance.
The beneficial effect of the utility model is following:
The utility model is simple in structure; Install with easy to use, increased leg on the backing plate with the inner clamping action of base, internal face direct and the watertight connector base contacts when making the rubber wick pressurized; But in the inner generation of backing plate leg crimp; Then the ejector internal structure is difficult for being stuck, and be easy to during use in base, extract, and the utility model can repeatedly use under high-pressure environment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.
As shown in Figure 1, the ejector of the described holding wire of the utility model comprises base 5; Base 5 inside have multi-layer groove; The ground floor bottom portion of groove is installed the first sealing ring 1-1, and the first sealing ring 1-1 goes up backing plate 2 is installed, and backing plate 2 has leg; Place rubber wick 3 in the leg of backing plate 2 and push down, leave extruding allowance 9 between cover plate 4 and backing plate 2 upper surfaces through cover plate 4; Through the second sealing ring 1-2 nut 6 is installed on the cover plate 4,5 of the excircle of nut 6 and bases are opened second layer groove internal face and are connected, and nut 6 bottoms are provided with step, and 5 of step and bases are opened between the internal face of second layer groove and left extruding allowance 7; Backing plate 2 bottoms have a plurality of fairleads 10; Have a plurality of through holes that cooperate with it on the rubber wick 3; Have the fairleads 8 that a plurality of and fairlead 10 and rubber wick 3 through holes are used on the cover plate 4, the quantity that fairlead 10, fairlead 8 and 3 of rubber wicks are opened the hole and specification are according to different application scenarios and requirements set.
In the actual use, when the utility model is applied to the cable ejector, accomplish drawing of cable through following steps:
The first step: the base 5 of ejector is installed on the pressure-resistant equipment through securing member;
Second step: place 5 of bases to open in the ground floor groove the first sealing ring 1-1; The backing plate 2 of mounting strap leg; And in backing plate 2, put into rubber wick 3, and cover cover plate 4 then, simultaneously the fairlead 10 of backing plate 2 bottoms, the through hole and the fairlead 8 on the cover plate 4 of rubber wick 3 are alignd accordingly;
The 3rd step: the cable that needs are drawn passes ejector base 5 and by the sealing ring of putting well 1, passes successively in the through hole and the fairlead 8 on the cover plate 4 of fairlead 10, rubber wick 3 of backing plate 2 bottoms of band leg again;
The 4th step: the alignment pin of upper cover plate 4 is aimed at the location notch of ejector 5, and be tightly connected through the second sealing ring 1-2, cover plate 4 can transfers and block the outage cable when preventing to screw clamping nut 6;
The 5th step: screw on clamping nut 6; Make cover plate 4 be pressed in rubber wick 3; Extruding allowance 9 between cover plate 4 and backing plate 2 upper surfaces diminishes; Simultaneously nut 6 steps and 5 of bases are opened and are left extruding allowance 7 between the internal face of second layer groove and also diminish, thereby rubber wick 3 is extruded to be out of shape in the backing plate 2 of band leg watertight cable is sealed up.
Just can realize drawing of cable easily through as above step, easy to operate, and ejector can repeatedly use, and cost is low; Because the crimp of rubber wick 3 is carried out, can not touch the internal face of base 5 in addition in backing plate 2, it is not easy stuck, also is easy in base 5, extract.The utility model can be widely used in ocean engineering, Underwater Engineering, test pressure tube and the chemical industry equipment pressure vessel.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion within the protection range of the utility model, can be done any type of modification referring to claim.
