The utility model is a mechanical interlocking valve which has a simple and compact structure, low cost, high operating sensitivity and good sealing effect, and is used for the fire extinguishing equipment.
Description
Technical field
The utility model is mainly concerned with the fire fighting apparatus field, refers in particular to a kind of mechanical interlocking valve that is used for fire fighting apparatus, is applicable to the gas-liquid secondary isolation device on the fire fighting apparatus.
Background technique
In present a lot of fire fighting apparatus the secondary isolation device is not set, though some equipment is provided with the secondary isolation device, adopts the passive type sealing, easily reveal long-term use back, and necessary manual reset after the equipment action, stays potential safety hazard.
The model utility content
Problem to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provide a kind of simple and compact for structure, with low cost, Operational Figure Of Merit is high, good sealing effect, can the automatically reset mechanical interlocking valve that is used for fire fighting apparatus.
For solving the problems of the technologies described above, the solution that the utility model proposes is: a kind of mechanical interlocking valve that is used for fire fighting apparatus, it is characterized in that: it comprises valve body and is inserted in the interior depression bar of valve body, offer gas-entered passageway and outlet passageway on one end of valve body, described gas-entered passageway and outlet passageway are interconnected by the communicated cavity in the valve body, be equiped with the piston seal assembly that is used for cutting off gas-entered passageway and outlet passageway on one end of described depression bar, be arranged with Returnning spring on the piston seal assembly.
Described piston seal assembly comprises piston that links to each other with depression bar and the piston head that is positioned at piston base, is equiped with the awl seal arrangement that is used to seal communicated cavity on the piston head.
Described gas-entered passageway links to each other with an air input joint, and outlet passageway links to each other with an air outlet adapter.
The end that described valve body links to each other with depression bar is provided with bonnet, and depression bar is inserted in bonnet and the valve body.
Compared with prior art, advantage of the present utility model just is: the utility model is simple and compact for structure, with low cost, Operational Figure Of Merit is high, good sealing effect, can automatically reset; By cooperating with the control system of fire fighting apparatus, can play good isolation effect, when needs are communicated with, can carry out the unlatching operation apace.The utility model adopts initiatively sealing means, and pressure is big more, and tightness is good more, is provided with Returnning spring simultaneously, possesses auto-reset function.

Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
Referring to Fig. 1, Fig. 2 and shown in Figure 3, a kind of mechanical interlocking valve that is used for fire fighting apparatus of the utility model, it comprises valve body 1 and the depression bar 15 that is inserted in the valve body 1, offer gas-entered passageway 3 and outlet passageway 4 on one end of valve body 1, gas-entered passageway 3 and outlet passageway 4 are interconnected by the communicated cavity 7 in the valve body 1, be equiped with the piston seal assembly that is used for cutting off gas-entered passageway 3 and outlet passageway 4 on one end of depression bar 15, be arranged with Returnning spring 6 on the piston seal assembly.In the present embodiment, the piston seal assembly comprises piston 5 that links to each other with depression bar 15 and the piston head 10 that is positioned at piston 5 bottoms, is equiped with the awl seal arrangement 9 that is used to seal communicated cavity 7 on the piston head 10, and the top of awl seal arrangement 9 is provided with taper liner 8.Gas-entered passageway 3 links to each other with an air input joint 12, and outlet passageway 4 links to each other with an air outlet adapter 14.The end that valve body 1 links to each other with depression bar 15 is provided with bonnet 2, and depression bar 15 is inserted in bonnet 2 and the valve body 1.In order to improve sealing effect, between piston seal assembly and valve body 1 inwall, between gas-entered passageway 3 and the air input joint 12 and be equipped with O RunddichtringO 13 between outlet passageway 4 and the air outlet adapter 14.
Working principle: be applied to the utility model that oil draining nitrogen filling is an example in the fire fighting apparatus, with an end of depression bar 15 link to each other with the driving mechanism of control system (for example cam drive), when the driving mechanism motion is depressed depression bar 15, Returnning spring 6 is in impaction state, piston head 10 and awl seal arrangement 9 move downward, disengaging cooperates with communicated cavity 7, and gas-entered passageway 3 is communicated with outlet passageway 4, finishes the unlatching operation.When depression bar 15 was left in the driving mechanism motion, under the restoring force effect of Returnning spring 6, depression bar 15 rose, driving the piston seal assembly up moves, awl seal arrangement 9 again with being sealed and matched of communicated cavity 7, isolate gas-entered passageway 3 and outlet passageway 4, finish and close operation.
