Description
The utility model relates to a kind of instrument that stops up valve, particularly a kind of manual safety dredging tool dredged.This instrument is applicable to the mediation of not stopping work of facilities such as the condensate drain point, sampled point of manufacturing enterprises such as petrochemical industry, loosening point, instrument pressure point.
At production industries such as oil, chemical industry, because the needs of technology and operation, device is provided with facilities such as many condensate drain points, sampled point, loosening point and instrument pressure point, as shown in Figure 1, these facilities generally are that valve one end is connected with process equipment, the other end is open ports then, or can the temporarily disconnected open ports.These facilities are usually because of reasons such as medium crystallization, impurity sedimentation, equipment corrosion, solid and mud, result in blockage and lose function.Before this, for the above-mentioned facility that has stopped up, Long-time Shut-down is brought many inconvenience and influence to production so often.If must processing, can only go to disclose with the Tie Tong bar under the prerequisite of security protection having no.Therefore many industries all once caused personal injury and accident such as catch fire.
The purpose of this utility model will provide a kind of manual safety dredging tool exactly, and it can make facilities such as the condensate drain point that stopped up, drain, sampled point, loosening point, instrument pressure point, under the state of not stopping work, obtains mediation safely and effectively.
The purpose of this utility model is achieved in that specifically be exactly a kind of manual safety dredge, by handle (1), drilling rod polished rod part (2), sealing locknut (3), sealing gland (4), sealed letter (5), Pressure gauge (6), pressure tapping (7), cylindrical shell (8), drilling rod screw portion (9), drive nut (10), many types of articulation (11), drill bit (12), relief valve joint (13), relief valve (14) constitutes, and it is characterized in that: adopt thread connection between sealing locknut (3) and the sealed letter (5), also adopt thread connection between sealed letter (5) and the cylindrical shell (8), adopt welding or whole processing between cylindrical shell (8) and the drive nut (10), screw rod (9) and drive nut (10) adopt two-wire or three-way trapezoidal thread to cooperate, and drive nut (10) is provided with pressure passageway (15).Said many types of articulation (11) has flange or internal thread or external screw thread shape, can be united together by the mediation valve with various.Said drill bit (12) adopts the steel alloy carpenter, and Y-40 series is adopted in said Pressure gauge (6) and pressure tapping (7), and said relief valve and relief valve joint (13) adopt D
g15 series.Connecting between said articulation (11) and the drive nut (10) is thread connection.Earlier dredge and the valve opening end of being dredged are connected with many types of articulation, the many types of articulation of dredge can with the threaded valve of multiple model, flanged valve connection.After connecting, open the valve that needs mediation, crank handle is advanced the drilling rod of dredge inwards, dredges.Dredge is provided with pressure-display device, after valve is dredged, the pressure indication is arranged promptly.At this moment, can withdraw from drilling rod, close by the mediation valve.In order to ensure the safety of mediation process, dredge is provided with the sealing device of 2.5MPa.In order to guarantee the safety of unloading process, dredge is provided with relief valve, and mediation finishes, and shuts earlier by the mediation valve, opens relief valve again, the overbottom pressure in the dredge is let out to the greatest extent, thereby guaranteed the safety of whole operation process.
The utility model structurally has following characteristics: adopt the inner screw formula, and the two ends of cylindrical shell, an end is a sealing device, an end is the screw drive nut, thereby makes integral body reach the compactness and the balance of maximum possible; Screw rod adopts two-wire or three-way trapezoidal thread, thereby makes manual gait of march improve two to three times; Drill bit adopts and to stretch into state in advance according to by the structure of mediation valve, and after dredge and valve were connected, drill bit just in time reached near the spool of valve, dredges stroke and reduces to the shortest thereby make; Cylindrical shell is a removable structure, and after each mediation, all removable cleaning has prevented dielectric corrosion and impurity retaining pressure display unit and relief valve.
The utility model is at the oil that taken a broad survey, and the condensate drain valve of chemical enterprise is developed on the basis of sampling valve and loosening dot structure.This dredge compact conformation, easy to carry, be to dredge the instrument that stops up valve safely and effectively.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a sample point valve schematic diagram on the equipment in the prior art.
Fig. 2 is according to the whole cutaway view of the assembling of the manual safety dredge that the utility model proposes.
Fig. 3 is the side view of drive nut among Fig. 2.
Describe details and working condition in detail below in conjunction with Fig. 2 and Fig. 3 according to the concrete device that the utility model proposes.
The utility model is made of 14 parts.Handle (1); Drilling rod polished rod part (2); Sealing locknut (3); Sealing gland (4); Sealed letter (5); Pressure gauge (6); Pressure tapping (7); Cylindrical shell (8); Drilling rod screw portion (9); Drive nut (10); Many types of articulation (11); Drill bit (12); Relief valve joint (13); Relief valve (14).Adopt thread connection between sealing locknut (3) and the sealed letter (5), can be in the use according to more being renewed filler by the operating pressure difference of mediation medium.Also adopt thread connection between sealed letter (5) and the cylindrical shell (8), used dredge can be opened from here and clear up.Sealed letter (5) also plays a part axle sleeve in addition.Adopt welding or whole processing between cylindrical shell (8) and the drive nut (10).Screw rod (9) and drive nut (10) adopt two-wire or three-way trapezoidal thread to cooperate, thereby the screw rod gait of march is accelerated.Drive nut is provided with pressure passageway (15), and (as shown in Figure 3) is so after valve was dredged, Pressure gauge (6) promptly had pressure to show.Many types of articulation (11) plays a part dredge with being associated in by the mediation valve.Owing to had multiple pattern, model by the mediation valve, so each dredge is furnished with the articulation (being called for short many types of articulation) of multiple model.Each articulation (11) is the same with connection between the drive nut (10), is thread connection, and of connecting with valve is different, and multiple pattern models (a kind of internal thread pattern only is shown among Fig. 2) such as flange, internal thread, external screw thread are arranged.Thereby make a cover dredge can satisfy the needs of different user most possibly.Drill bit (12) adopts steel alloy carpenter commonly used in the prior art, thereby most impurity can be gone out clearly, and does not disclose in the process pipe.Y-40 series is adopted in Pressure gauge (6) and pressure tapping (7), and relief valve (14) adopts D with relief valve joint (13)
g15 series, thus the gross weight of dredge alleviated as much as possible.
