Description
Technical field
The utility model relates to a kind of hydrant, relates in particular to a kind of detachable voltage-regulation type outdoor fire hydrant.
Background technology
Nowadays at present; Petrochemical enterprise has much with the hydrant of municipal administration use at home, and plain edition, crash-proof, voltage-regulation type etc. are arranged, but these hydrants all exist one to be difficult to its problem of keeping in repair; The region that particularly northerly frostproof course requires; Normally will whole hydrant be broken ground and dig out, be to lose time very much and increase maintenance cost like this, and the efficient of maintenance is also very low.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of the utility model is to provide a kind of detachable voltage-regulation type outdoor fire hydrant that on the basis of common fiery bolt, has increased pressure regulation, decompression voltage stabilizing and be easy to remove and repair.
To achieve these goals; The utility model adopts following technical scheme: a kind of detachable voltage-regulation type outdoor fire hydrant; It comprises protecting cover, five-way key, bolt base, delivery port, water sucking mouth; The special spanner that matches with it on control stick in the protecting cover, the control stick, drive nut is connected through screw mandrel with control stick, and the lower end of drive nut is connected with hollow connecting rod; Valve module and reducing valve are connected as a single entity with drive nut and cooperate and be installed on the removable guiding device, and automatic drain valve is arranged on the side of bolt base.Be with the reducing valve cover in the periphery of reducing valve.
. operating principle: be buckled in special spanner on the control stick, rotate counterclockwise then, drive drive nut in the time of rotation and move upward; Adopt screw mandrel to be connected between drive nut and the control stick, drive nut is to be welded on the hollow connecting rod, and pressure regulator valve is to be fixed on the hollow connecting rod by bearing pin; Valve module is to be connected with hollow connecting rod through screw thread, so, when drive nut 3 moves upward; Drive is attached thereto the hydrant interior fittings integral body that connects and moves upward, and along with the slowly unlatching of valve module, it is inner that pipeline pressure water fills up whole hydrant immediately; Be connected with fire-extinguishing apparatus through fire hose, reaching the effect that stamps out a fire.Automatic drain valve hydrant have press water through the time pressure close automatically during more than or equal to 0.20MPa.Clockwise rotate special spanner, then to rotate counterclockwise special spanner opposite with it for hydrant internals motion, and hydrant cuts out, and automatic drain valve is opened the surplus water of getting rid of in the hydrant automatically when the bolt internal pressure is less than or equal to 0.20MPa.Hydrant is when cutting out, and when the lower surface and the pressure regulator valve of hydrant inner pressure relief valve puts end face will contact the time, at this moment, the sealing surface of valve module just contacts with sealing surface on the base, is rotated further special spanner, and promptly valve module is closed in the hydrant.And pressure regulator valve is divided into the hydrant inside water pressure chamber of two kinds of pressure in hydrant; Form pressure reduction; Hydrant pressure regulator valve upper pressure makes hydrant reduced by pipeline hydraulic action power less than pressure regulator valve bottom pressure, and then hydrant can easily cut out.
The beneficial effect of the utility model:
1, the utility model is a kind of function that on the basis of common fiery bolt, has increased pressure regulation, decompression voltage stabilizing and be easy to remove and repair; Can improve the practicality of hydrant greatly at fire protection sector.
2, the utility model can extensively be installed on enterprise, the public institution of municipal administration, all trades and professions.Particularly can be used on oil, chemical industry, grain storage and goods processing, timber and goods, light textile, port and pier, airport, storage reservoir area or the like all types fire prevention unit.More can be relieved be used for north cold area.With the unit optimal selection especially of seawater or industrial wastewater as fire fighting supply.

Fig. 2 is a detachable and independent pilot structural representation partly among Fig. 1.
Fig. 3 is the structural representation of pressure regulation among Fig. 1, decompression and self-draining arrangement part.
The specific embodiment
Detail below in conjunction with Fig. 1,2,3 pairs of the utility model: a kind of detachable voltage-regulation type outdoor fire hydrant; It comprises protecting cover I, five-way key III, bolt base VI, delivery port IV, water sucking mouth V; The special spanner 1 that matches with it on control stick 2 in the protecting cover I, the control stick 2; Drive nut 3 and control stick 2 are connected through screw mandrel; The lower end of drive nut 3 is connected with hollow connecting rod 4, and valve module 7 is connected as a single entity with drive nut 3 and cooperates with reducing valve 5 and is installed on the removable guiding device II, and automatic drain valve 8 is arranged on the side of bolt base VI.Be with reducing valve cover 6 in the periphery of reducing valve 5.
Pressure regulation and decompression voltage stabilizing function: the opening process of this hydrant is the mode that a kind of segmentation is opened; Open control stick 2 with special spanner 1; Valve module 7 is to be connected as a single entity and to be engaged on the removable guiding device II with reducing valve 5 because with drive nut 3; So 7 one-tenth of valve modules are motion vertically upward, open this moment press water get between valve module 7 and the reducing valve 5, this is one section; Continue to open, valve module 7 continues to move upward with reducing valve 5 simultaneously, and this moment, press water got into five-way key III through reducing valve 5; This is two sections, transfers out press water by delivery port IV or water sucking mouth V again, one section space and two sections pressure differentials that the space forms in the process that segmentation is opened; Can play the initial pressure that reduces outlet; Prolong and saliva band and the user adaptation time to outlet hydraulic pressure, improve the safety of user and water band, this is for reducing pressure and voltage stabilizing; Owing to be that segmentation is opened, hydrant can be regulated outlet pressure in the process through decompression and voltage stabilizing, selects suitable outlet pressure, and it is the pressure meter on the five-way key that its outlet pressure shows, it is pressure regulation.
Detachable function: when break down in hydrant inside; Can not need whole hydrant split is keeped in repair, the water supply valve of closing fault hydrant, I takes off with instrument with protecting cover; With instrument the screw that removable guiding device II is fixed on the five-way key III is taken off again; Towards opening direction (counterclockwise) rotation, control stick 2 is automatic and drive nut 3 disengagings after certain number of turns with special spanner 1, and this moment can be with removable guiding device II and control stick 2 one whole taking-ups; Again hollow connecting rod 4, reducing valve 5 are repaired or replaced with valve module 7 whole taking-ups.Above opposite program assembling moulding is got final product after maintenance is accomplished, this is detachable convenient for maintaining again.
Automatic drain function: the automatic draining of original hydrant is glass marble sealing or machine driving sealing basically; Glass marble seal request sealing surface is higher, if service time of a specified duration sealing surface to have wearing and tearing or foreign material to get into the effect that drain all can't play sealing; And less demanding to sealing surface of machine driving sealing, but transmission mechanism works in water for a long time, and the material of requirement is had relatively high expectations, and also can't avoid foreign material to get into drain; My this hydrant self-draining arrangement of company is to use flat seal; Relying on hydraulic pressure self to overcome the draining valve spring seals; Good sealing effect; And, make foreign material etc. can't get into the inside of draining valve at the sealing surface of draining valve periphery mounting filtering device, well avoided the fault rate of automatic drain valve.
