Embodiment
Referring to figs. 1 through Fig. 3, the utility model fire-fighting ball valve embodiment is described further.
As shown in Figure 1, present embodiment discloses a kind of concrete structure of fire-fighting ball valve, the present embodiment comprises valve body 11 and the bolted valve gap 12 of valve body 11, and is provided with ball core 2 in valve body 11;
Wherein, the present embodiment is communicated with valve body 11 and valve gap 12 by ball core 2, and therefore roating sphere core 2 can realize the connection of the pipeline of the present embodiment.
Particularly, the present embodiment be rely on valve rod 31 through after the operation port 13 be opened on valve body 11 and ball core 2 coaxial rotation open and close to realize pipeline.
Designing points of the present utility model is, ball core 2 offers the spacing groove 21 being communicated with ball core 2 inside, and valve rod 31 is plugged in spacing groove 21; Therefore, when outside drawing valve rod 31, valve rod 31 can be made to be separated with spacing groove 21; Meanwhile, clamping sleeve 5 has been abutted between valve rod 31 and the inwall of operation port 13; And the locations of structures of operation port 13 between clamping sleeve 5 and spacing groove 21 offers fire-fighting through hole 131.The object that the utility model designs like this is, when the urgent fire-fighting of needs, by outside drawing valve rod 31, valve rod 31 is separated with spacing groove 21, now fluid can enter to operation port 13 through spacing groove 21, enter to the restriction of fluid due to clamping sleeve 5 of operation port 13, the external world can only be flow to from fire-fighting through hole 131.Here clamping sleeve 5 can teflon or have flexible rubber filling thing.
In addition, as shown in figures 1 and 3, this enforcement only gives the mode of execution be more preferably, one end of the spacing groove 21 of valve rod 31 grafting is along its bar to offering two slots to make way 311, its role is to, when the urgent fire-fighting of needs, only need outside drawing certain distance, make fluid flow into operation port 13 through two slots to make way 311 and the gap of spacing groove 21, then flow out fire-fighting through hole 131.The object of such design is, when avoiding operation, needs valve rod 31 to extract completely from spacing groove 21, can allow fluid flow into in operation port 13.
As shown in Figure 2, be equipped with sealing station 132 outside the operation port 13 of the present embodiment, and sealing station 132 is arranged on the below of fire-fighting through hole 131; Simultaneously, valve rod 31 is fixed with sealing station 132, sealing station 132 can along the bar of valve rod 31 to the upper surface of conflicting in sealing station 132, the object of such setting is, when one end of valve rod 31 is plugged in spacing groove 21, seal valve and sealing station 132 conflict to form sealing surface, prevent the seepage under non-emergent fire fighting state further.
Preferably, seal ring 4 is fixed with at the upper surface of sealing station 132, seal valve is under the state of non-emergent fire fighting state and the spacing groove 21 of valve rod 31 grafting, conflict on seal ring 4, and seal ring 4 adopts rubber or silica gel to make usually, seal valve abuts sealing station 132 by seal ring 4, can strengthen sealing effect further, prevent seepage.
In addition, continue referring to Fig. 2, the present embodiment be preferably circumferentially with leakproof platform 133 at the inwall of operation port 13, clamping sleeve 5 is conflicted at the upper surface of leakproof platform 133.Such design can form stepped sealed between clamping sleeve 5 and operation port 13 inwall, and anti-fluid is oozed out from the gap of clamping sleeve 5 and operation port 13.
In addition, valve rod 31 is fixed with turning handle 32 relative to the other end of the spacing groove 21 of its grafting, is convenient to rotate or drawing valve rod 31.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
