Abstract
An outdoor hydrant able to be installed in manhole features that the guide pipe between its pipe jointer and water outlet of water valve has the sealed telescopic internal and external sleeve pipes structure with limiter and the valve axle between handwheel and valve flap has the sleeved telescopic structure with slide spline and spline slot.
Description
Technical field
The present invention relates to a kind of Outdoor Fire Hydrant.
Background technology
Present Outdoor Fire Hydrant all is fixedly mounted on the supply channel.Some exposure is installed on the ground, and some is installed in underground.Exposure is installed, and is easy to be subjected to machinery and damages, and simultaneously, easy split robber of precious metal parts of assembling causes a large amount of economic losses to country on it.Place underground, though solved the problems referred to above, because the position is lower, breaking out of fire in emergency circumstances can not connect fast and establish Flexible water pipe, miss the opportune moment of the disaster relief sometimes; Simultaneously, above-mentioned fire plug mounting means is fixed, and the union direction is fixed, but the Flexible water pipe trend is unfixing, maybe need get around obstacle, or needs pulling back and forth, often inconsistent to cause Flexible water pipe to scratch curved owing to union direction and Flexible water pipe move towards, and it is not smooth to supply water, and influences fire-fighting operation and disaster relief effect.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of Outdoor Fire Hydrant, to make things convenient for fire-fighting operation, it is unobstructed to guarantee to supply water.
For achieving the above object, technical program of the present invention lies in providing a kind of Outdoor Fire Hydrant, comprise water valve and union, the internal and external casing structure that conduit between union and the valve body outlet pipe cooperates for the sealing sliding extension, be provided with elongation limit stopping means between the fitting face of internal and external casing, valve shaft between handwheel and the flap is the flexible fit structure of plug bush type, is provided with the axial feather key that cooperatively interacts, keyway between the sleeve fitting face.
The inner sleeve of the internal and external casing structure that described sealing sliding extension cooperates is fixed on the valve body as the outlet pipe of valve body, outer tube slides as telescoping tube and is set on the inner sleeve outer tube surface, the face of being slidingly matched is one to be in the annular convex surface of outer tube lower end, be embedded with " O " shape sealing ring in the groove on the annular convex surface, the upper edge of annular convex surface is semicircle steel bowl confined planes, the top of inner sleeve outer tube surface is provided with an annular semicircle groove, has folded up a circle steel ball between semicircle groove and the outer sleeve inner wall face.
Described plug bush type is flexible to cooperate valve shaft to be made of the major axis that is assembled together with handwheel and the sleeve pipe of the outer slip suit of major axis, and the top seal of major axis is rotated and is installed on the top cover of outer tube, and the screw rod rotating shaft of the lower end of sleeve pipe and flap fixedly is assembled together.
Because the internal and external casing structure that cooperates for the sealing sliding extension between union and the valve body outlet pipe, be equipped with the flexible fit structure of plug bush type of valve shaft, conduit can be flexible up and down on valve body, and it is underground to make that fire plug of the present invention can be assemblied in, and has avoided the possibility of various damages.Simultaneously, after ground cover is locked, also can be antitheft, reduced a large amount of maintenance works, saved use cost greatly.During use, can operate and pull out ground, the time spent does not descend retractedly, and it is attractive in appearance not influence ground, can not cause traffic obstacle.In addition, this structure also makes outer tube can do 360 ° rotation around inner sleeve, makes union can do the rotation of any direction with water-supply-pipe, has avoided scratching curved generation, and it is smooth and easy to have guaranteed to supply water, and helps fire-fighting operation.What deserves to be mentioned is that the present invention is designed to one to valve shaft and the internal and external casing that flap drives, assembling is simple, and the structural coordination compactness occupies little space, and is easy to install and use, and good using value is arranged.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the valve body of fire plug of the present invention is similar to existing product with the union part, so each parts annexation of product repeats no more, component names shown in each label is as follows among the figure: 1, valve body, 2, screw, 3, planchet, 4, rubber cushion, 5, flap, 6, rubber cushion, 7, round nut, 8, the spilling water screw, 9, extrusome, 10, pad, 11, " O " shape sealing ring, 12, bolt, 13, steel ball, 14, valve gap, 15 " O " shape sealing ring, 16, round nut, 17, rubber cushion, 18, screw, 19, union, 20, feather key, 21, telescopic, 22, sliding key shaft, 23, seamless pipe, 24, screw mandrel, 25, clasp nail, 26, the bullet pad, 27, plain cushion, 28, nut, 29, bolt, 30, wire loop.
Distinctive feature of the present invention is: the internal and external casing structure that the conduit between union 19 and valve body 1 outlet pipe cooperates for the sealing sliding extension, be provided with elongation limit stopping means between the fitting face of internal and external casing, valve shaft between handwheel and the flap 5 is the flexible fit structure of plug bush type, is provided with the axial feather key that cooperatively interacts 20, keyway between the sleeve fitting face.The inner sleeve of the internal and external casing structure that the sealing sliding extension cooperates is fixed on the valve body 1 as the outlet pipe of valve body 1, outer tube slides as telescoping tube and is set on the inner sleeve outer tube surface, the face of being slidingly matched is one to be in the annular convex surface of outer tube lower end, be embedded with " O " shape sealing ring 15 in the groove on the annular convex surface, the upper edge of annular convex surface is semicircle steel bowl confined planes, the top of inner sleeve outer tube surface is provided with an annular semicircle groove, folded up a circle steel ball 13 between semicircle groove and the outer sleeve inner wall face, plug bush type is flexible to cooperate valve shaft to be made of the major axis that is assembled together with handwheel and the sleeve pipe of the outer slip suit of major axis, the top seal of major axis is rotated and is installed on the top cover of outer tube, and the screw rod rotating shaft of the lower end of sleeve pipe and flap 5 fixedly is assembled together.
During use, fire plug integral body can be installed on the underground main line, union 19 and the operated by handwheel part ground of can pulling out as required or withdraw, and simultaneously, union 19 can be done 360 ° rotation at circumferencial direction.
