Description
Technical field
The utility model relates to a kind of fire-fighting equipment, specifically is meant a kind of quick pressure regulation crash-proof outdoor fire hydrant.
Background technology
Outdoor fire hydrant is mainly used in to fire fighting truck provides water for fire or direct the connection with the fire hose hydraulic giant to put out a fire, and is the fire fighting supply facility of city utilities building, industrial and mining enterprises, public place indispensability.Common outdoor fire hydrant is in the fire-fighting fire extinguishing process, and hermetically-sealed construction is that the outdoor fire hydrant of press-down type booster takes place easily being damaged, and hermetically-sealed construction to be the hydrant of pull-up open relatively difficulty when breaking out of fire.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, provide a kind of sealing performance reliable, open rapidly flexibly, the high quick pressure regulation crash-proof outdoor fire hydrant of water shutoff performance automatically.
The purpose of this utility model is achieved through the following technical solutions: quick pressure regulation crash-proof outdoor fire hydrant, comprise hydrant body and the connector that is arranged on the hydrant body interior, be set with seal on the described connector, the top of described seal is provided with along the hydrant inner body wall and is the seal receptacle that the footpath concaves.
Above-mentioned seal mainly is made of sealing mat, and sealing mat is fixed together by fixture and connector, and mainly the top board and the lower platen at two ends constitute fixture up and down by being separately positioned on sealing mat.
Be provided with regulator between above-mentioned seal and the connector, regulator mainly is made of the outer sleeve that is sleeved on the inner sleeve on the connector and is arranged on the inner sleeve outside, constitute the pressure regulation passage between described inner sleeve and the outer sleeve, and the bottom of pressure regulation passage is enclosed construction, the sidewall bottom of described outer sleeve is provided with regulator hole, and the sidewall top of outer sleeve is provided with and is the radially fixture block of evagination.
Above-mentioned connector mainly is made of the guide peg of taking over and link to each other with the adapter lower end, and described adapter mainly is made of upper connecting tube that welds together and lower linking tube.
Above-mentioned seal receptacle is provided with drain hole, and draining valve is installed in the drain hole, and after hydrant was finished using, the Yu Shuike in the valve body was drained by draining valve.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) sealing performance is reliable: this hydrant has the reaction sealing performance, the double action of hydraulic pressure and connector pulling force adopts positive-pressure type flap structure, owing to can be closed hydrant very like a cork, compare with the hydrant of traditional press-down type hermetically-sealed construction, sealing performance improves greatly.
(2) open rapidly flexibly: this hydrant is provided with regulator, guaranteed in case of emergency can open hydrant fast, when emergency needs hydrant to open, the regulator that is equipped with in this hydrant body can overcome hydraulic action and open hydrant fast, regulator is at first opened when promptly being rotatably connected body, make the municipal water supply of network of underground enter the hydrant epicoele by regulator earlier, make seal pressure at both sides balance, easily open hydrant fast thereby can overcome hydraulic pressure.
(3) automatic water shutoff performance height (crashworthiness is good): this hydrant is damaged even is severed, and under the effect of pressure of supply water, the sealing position still can keep sealing, and hydrant can be finished automatic closing function, prevents the generation of accidents such as booster.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment:
As shown in Figure 1, 2, the utility model comprises hydrant body 1 and the connector that is arranged on hydrant body 1 inside, connector mainly is made of the guide peg of taking over and link to each other with the adapter lower end 11, takes over mainly to be made of upper connecting tube 12 that welds together and lower linking tube 13; Be set with sealing mat 3 on the described guide peg 11, sealing mat is respectively arranged with top board 4 and lower platen 5 in two ends about in the of 3, and top board 4 and lower platen 5 are fixed together sealing mat 3 and guide peg 11; The top of described sealing mat 3 is provided with along hydrant body 1 inwall and is the seal receptacle 2 that the footpath concaves.
Be provided with regulator between described sealing mat 3 and the guide peg 11, described regulator mainly is made of the outer sleeve 7 that is sleeved on the inner sleeve 6 on the guide peg 11 and is arranged on inner sleeve 6 outsides, constitute pressure regulation passage 8 between described inner sleeve 6 and the outer sleeve 7, and the bottom of pressure regulation passage 8 is enclosed construction, the sidewall bottom of described outer sleeve 7 is provided with regulator hole 9, and the sidewall top of outer sleeve 7 is provided with and is the radially fixture block 10 of evagination.
Described seal receptacle 2 is provided with drain hole 14, and draining valve 15 is installed in the drain hole 14.
Because the utility model has adopted said structure, thereby have excellent sealing performance, crashworthiness, quick pressure regulation unlatching performance, now be described respectively at three kinds of performances:
1, sealing performance: the utility model has adopted the positive-pressure type flap structure opposite with traditional hydrant, leans on the pressure effect of fire water in the system pipe network to seal, rather than relies on the active force of valve rod that flap is sealed.Under usual closed condition, connector does not stress, seal is subjected to the pressure effect of fire water in the system pipe network and is pressed on the seal receptacle 2, as shown in Figure 3, thereby played sealing function, and sealing load increases along with the increase of system water pressure, has effectively guaranteed the sealing effectiveness of hydrant.This structure makes the sealing of hydrant no longer rely on the support force of connector, and when hydrant runs into external force collision, when connector was twisted into two parts, seal still can lean on the effect of hydraulic pressure to keep sealing state, pipe explosion accident can not occur.
2, crashworthiness: the crashworthiness of this product is meant after fire plug is subjected to serious bump, booster can not occur, and the sealing position still can keep sealing.
The inner adapter of this hydrant is welded by two sections, also fracture thereupon of this weld when hydrant is subjected to the damage of external force collision key, so just guaranteed that the sealing position is not damaged, by the effect of pipe network system self hydraulic pressure, the sealing that seal still can be remained valid.
3, performance is opened in pressure regulation fast: this hydrant has adopted two sections release of pressure opening structures, is provided with regulator between sealing mat 3 and guide peg 11.When being rotatably connected body when initial unlatching hydrant, the very little regulator of water active area that is stressed at first moves down, at this moment fire water enters pressure regulation passage 8 by regulator hole 9, and finally enters the top cavity of seal, makes the pressure balance of cavity up and down of seal; Because the sidewall top of outer sleeve 7 is provided with and is the radially fixture block 10 of evagination, thereby only need very little opening force, fixture block 10 drive seals are moved down and final and seal receptacle 2 disengagings, the hydrant complete opening, as shown in Figure 4, so just fully guaranteed in case of emergency can open hydrant fast.
As mentioned above, just can realize the utility model preferably.
