Abstract
The utility model relates to a novel work carrier type anti-theft well mouth device. At present, well mouth devices which are widely used in the market always appears that parts and crude oil are stolen to influence production and cause economic loss. In the utility model, a semicircle anti-theft baffle plate and a concave convex groove are arranged on the work carrier, and the work carrier is fixed by nonstandard taper-shaped nine-angle nuts; the taper-shaped nine-angle nuts and cryptomorphic tight-stopping screws are arranged in a gate valve; a big four-way junctions are fixed by the taper-shaped nine-angle nuts. Ordinary tools can not detached and open the parts, and thereby, the safety of the whole well mouth device and the crude oil are guaranteed. The utility model has the advantages of novel structure and theft resistance.
Description
The utility model relates to a kind of novel clamping hoop type Pithead preventing thieves device.
At present, widely used wellhead assembly on the market all is that universal standard part connects generally, thereby accessory and the stolen phenomenon of crude oil often takes place, and has influenced production, causes economic loss, has brought certain difficulty to management.Therefore, people urgently wish to have a kind of appearance of novel anti-theft wellhead assembly, thereby overcome above-mentioned shortcoming.
The purpose of this utility model is to provide a kind of novel clamping hoop type Pithead preventing thieves device.
The utility model is achieved through the following technical solutions, it comprises compositions such as little four-way, choke valve, stop valve, gate valve, clip, nine jiaos of nuts of taper, tubing head, pressure meter, taper one word spanner, the outside of clip is provided with semicircle antitheft baffle plate, be provided with tongue and groove between the two parts of working in coordination, and clip two parts fixed with nine jiaos of nuts of taper.The gate valve outside is provided with two stealthy fastening bolts, is provided with nine jiaos of nuts of taper in the gate valve, also is furnished with the taper one word spanner that cooperates with nine jiaos of nuts of this taper.
The utility model novel structure has advantages such as antitheft, practicality.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model general assembly structure chart
Fig. 2 is the yoke configurations schematic diagram
Fig. 3 is nine jiaos of nut structure schematic diagrames of taper
Fig. 4 is the gate valve structure schematic diagram
In the accompanying drawing, 1 is that clip, 2 is that little four-way, 3 is that gate valve, 4,5 is that nine jiaos of nuts of taper, 6 are that big four, 7 is that shutoff valve, 8 is that stop valve, 9 is that pressure meter, 10 is that groove, 11 is that tongue, 12 is that semicircle antitheft baffle plate, 13 is that taper one word spanner, 14 is that nine jiaos of nuts of taper, 15,16 are stealthy fastening bolt.
As shown in Figure 1, gate valve 3, little four-way 2, big four 6, shutoff valve 7, stop valve 8, pressure meter 9 all is to connect by clip 1, clip 1 is provided with semicircle antitheft baffle plate 12 shown in Figure 2, groove 10, tongue 11, two parts of clip 1 are fixing by nine jiaos of nuts of taper shown in Figure 34, two faces that are not parallel to each other on nine jiaos of nuts 4 of taper, general purpose tool can not degree of tightness, thereby have only with special tool and just can fix and unclamp, semicircle antitheft baffle plate 12 had both made pipe silk pincers, common tools such as wrench can not be dismantled, also prevented to interrupt nine jiaos of nuts 4 of taper with external force by force, groove 10, the cooperation of tongue 11 guarantees that the centre of clip 1 bolt is not cut, thereby makes clip 1 play antitheft effect; Fixing with nine jiaos of nuts of a plurality of tapers shown in Figure 34 on the big four 6, general big four uses in " 11 " below zero, and common tool can not be dismantled, and plays antitheft effect; Gate valve 3 inside are provided with nine jiaos of nuts 14 of taper, have only with the taper one word spanner 13 that is used with it and just can close and open, thereby general purpose tool can not cooperate nine jiaos of nuts 14 of taper, stealthy fastening bolt 15,16 ends frustrates plain valve head at once behind the tight valve body and lumps together, only is convenient to bore with the grade of steel assigned address and repaiies.Thereby, the assurance that nine jiaos of nuts 14 of taper and fastening bolt 15,16 are strong gate valve be not opened, thereby play the stolen effect that prevents.
Effectively guarantee theftproof performance of the present utility model by clip 1, big four 6, gate valve 3 in sum, played antitheft effect.
The utility model novel structure has the advantages such as antitheft, practicality.
