Abstract
A special tool for drilling holes with gas for the gas industry comprises a sealed pressure bearing body connected with a valve body and can bear 0.6 Mpa pressure, wherein the front end of the sealed pressure bearing body adopts a quick connection yarn end for connecting with a gas ball valve and a special reducing tee in construction, so as to form a sealed main body space; a rotary main shaft is nested inside the sealed pressure bearing body, and a micro-motion feed quick return mechanism is sleeved outside the sealed pressure bearing body; drilling heads are connected at two ends of the rotary main shaft, a wrench with hand-rotatable torque and capable of performing unidirectional cutting to the mechanism is linked with the micro-motion feed quick return mechanism. The utility model has the advantages that the tool can be freely manually operated for construction in any narrow space or installation position, and has the benefits of safe and reliable use, extensive application range, convenient construction and operation for professional construction workers, and low cost.
Description
Technical field:
The utility model relates to a kind of device that uses in gas industry, particularly a kind of gas industry is with being with air to open hole instrument.
Background technology:
At present, gas industry system is to Domestic Gas, especially newly the unit standpipe house lead in branch (family) that builds a building will carry out the engineering laying with arrangement and method for construction such as common malleable iron reducing tee multi pack ball valve, gas meter, pipeline, terminal valves with adopting between every layer of standpipe usually.Unavoidable problem of this mounting means ubiquity: as long as total pipeline is opened the valve ventilation, so, just can light a fire and use gas in every layer of branch family, so just bring a very thorny difficult problem to management.For the requirement of hommization harmonious society, combustion gas department gives one's hand: as long as building has the people to move in just necessary air feed.Yet do not move in the family, room of but selling and just may use combustion gas without authorization, improve gradually, stop today of run, drip, leak, reduce the national resources loss, prevent to usurp source of the gas, with regard to the seriousness that highlights problem more and the necessity of strick precaution at the combustion gas cost.Thereby instructions for use has not under the new situation been satisfied in original common reducing tee.And the reducing tee of new construction needs special-purpose instrument to open.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of gas industry with being with air to open hole instrument, and this instrument and gas industry can prevent to usurp source of the gas effectively with the supporting use of special-purpose reducing tee, guarantee gas industry steam line safety.
The technical solution of the utility model is: a kind of gas industry is with being with air to open hole instrument, it is characterized in that: comprise the seal and pressure bearing body that is connected and can bears 0.6MPa pressure with valve body, its front end is quick connecting filament head, that bears when construction and fuel gas ball valve, special-purpose reducing tee is connected the principal space of a sealing of formation; The inner suit rotary main shaft of seal and pressure bearing body, seal and pressure bearing external body suit micrometer feed rapid return mechanism; The rotary main shaft front end connects drill bit, back segment connect can unidirectional cutting mechanism manual rotation torque handle, and relevant interlock with micrometer feed rapid return mechanism.
Above-mentioned micrometer feed rapid return mechanism is made up of quadric chain.
Above-mentioned can the composition by ratchet and handle by unidirectional cutting mechanism.
The utility model has the advantages that: special-purpose reducing tee is under the design's cooperation, and any narrow space and installation site all can free manual operation constructions.Can make professional construction personnel safety operation under the state of operation under pressure, special-purpose reducing tee scene is become common reducing tee, standard is among the regular operational procedure of industry again.Therefore, this product safety is reliable, and the scope of application is extensive, and convenient for professional construction personnel constructing operation, cost is cheap.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model and the special-purpose reducing tee schematic diagram when being used.
The specific embodiment:
As shown in Figure 1: 1 is that seal and pressure bearing body, 2 is that rotary main shaft (connection drill bit), 3 is unidirectional cutting mechanism, 4 to be that micrometer feed rapid return mechanism, 5 is that main riser road, unit, 6 is that special-purpose reducing tee, 7 is that special-purpose ball valve, 8 is that specific purpose tool, A are that unit air inlet, B are that gas outlet, unit, C are house lead in reducing mouths.
Seal and pressure bearing body 1 is a main body, and its front end is quick connecting filament head, bears being connected of when construction and fuel gas ball valve, special-purpose reducing tee, constitutes the principal space of a sealing, the still special-purpose simultaneously body of accepting of being with air to open hole other parts of specific purpose tool.Seal and pressure bearing body 1 inner suit rotary main shaft 2, the outside suit micrometer feed rapid return of seal and pressure bearing body 1 mechanism 4.Rotary main shaft 2 front ends connect drill bit, back segment connect can unidirectional cutting mechanism 3 manual rotation torque handle, and relevant interlock, the function that the realization single shaft is used more with micrometer feed rapid return mechanism.Can unidirectional cutting mechanism, to form by ratchet and handle, realization is all machinable function of any direction of the anglec of rotation arbitrarily.Micrometer feed rapid return mechanism 4 is made up of quadric chain, has the function of regulating direction, regulating initial length and bit location and micrometer feed rapid return.
This cover band air to open hole specific purpose tool can bear 0.6MPa pressure, can realize the function that unidirectional dextrorotation is manually easily holed.During site operation, the perforate specific purpose tool and the special-purpose reducing tee of the design's structure, the special-purpose ball valve of combustion gas are connected together fast, can regulate service orientation according to the job site concrete condition.Move quick, micrometer feed mechanism 4 handles of linkage, make rotary main shaft 2 drive drill bits and arrive at anti-theft gaseous rapidly with sealing stifled core front end.An other hand half cycle turning moment spanner, driven rotary main shaft 2 and drill bit thereof are rotated in the forward cutting, simultaneously, mode with its coherent micrometer feed, move the handle of micrometer feed mechanism 4, under its sequence work, can get through anti-theft gaseous fast and block up core with sealing.After this, oppositely move rapid return mechanism 4 chisel edge is retreated to the outer end of fuel gas ball valve, valve-off unloads band air to open hole specific purpose tool, finishes the perforate operation procedure.
