Abstract
The utility model provides a manual antitheft flat plate valve, which is completely applicable to a well opening device and a throttling and killing manifold in petroleum industry. The internal design dimension of an original main body and the total length assembly dimension of connectors between relevant parts of the manual anti-theft flat plate valve are not changed. Only a right end surface flange of the flat plate valve is omitted and is changed into a cylinder, the inside of the cylinder is processed into a through hole, a section of pipe screw threads are formed at the right outer side of the through hole and are connected with a corresponding pipeline for realizing an antitheft effect. Therefore the manual antitheft flat plate valve has the advantages that the structure is compact and reasonable, the antitheft effect is realized, leakage points are reduced, and the absolute safety of the flat plate valve after the connection with a petroleum pipeline is ensured.
Description
Technical field
The manual antitheft flap type of the utility model improves right side linkage structure, after improving, valve is applicable to petroleum industry wellhead assembly and throttle kill manifold completely, do not change the former design size of manual antitheft flap type body interior and relevant between the overall length fitted position that connects.
Background technique
Manual antitheft flap type is a kind of professional component of oil field pipe, and it is arranged in wellhead assembly and throttle kill manifold.It is according to " O " type groove, stuffing box packing in addition, then fastening by 8 screw bolt and nut on uniform 8 circular holes, flange plate contact plane on left and right both ends of the surface flange plate, flange plate that former flap type is connected with pipeline.This connecting means drawback is to cause unnecessary loss as long as can take the set screw nut on the flange plate of left and right, disassembling bolts away flap type.
Summary of the invention
The manual antitheft flap type improved connection structure technological scheme of the utility model is to retain on flap type left side mounting flange (3), flange plate " O " type groove (5) on uniform 8 circular holes (4), flange plate contact plane to be connected with pipeline; Flap type right side flange plate removes and makes cylindrical body (1) into, in cylindrical body (1), is processed into through hole, and the right outside side of through hole is that one section of pipe thread (2) is connected with pipeline, and it is constant that flap type connects overall length.
The utlity model has compact structure, reasonable, antitheft, reduce leakage point and guarantee flap type work advantage safe against all possibilities.
Accompanying drawing explanation
Fig. 1 is main TV structure figure of the present utility model.
In the accompanying drawings: 1 cylindrical body, 2 pipe thread, 3 flange plate, 4 circular holes, 5 " O " type groove.
Embodiment
The not flanged dish in right side when the manual antitheft flap type valve body blank of processing, its left end is by former design processing; Its right-hand member is processed into cylindrical body, is processed into through hole in cylindrical body, and the right outside side of through hole is one section of pipe thread.
Claims (1)
1. manual antitheft flap type is to consist of " O " type groove (5), flap type right side cylindrical body (1), pipe thread (2) on uniform 8 circular holes (4), flange plate contact plane on flap type left side flange plate (3), flange plate, it is characterized in that: flap type left side flange plate (3) is connected with pipeline, flap type right side is connected with pipeline by pipe thread (2).
