The present invention compares with background technology, and the beneficial effect that has is:
(1) the maximum difference of the present invention and other like product is directly to adopt fire-extinguishing location press water commonly used as power source, the corresponding variation took place in the water pressure in two independent hydraulic pressure chambeies about change by 3-position 4-way pure water electromagnetic switch valve core operating position made, slidably reciprocate along the nozzle body axial direction thereby drive nozzle, realize that direct current sprays and the automatic steady conversion of spray injection.
(2) water pressure that provides by current self, omit the outside executing agency and the control appliance thereof of conventional hydraulic control or electronic control, eliminated hydraulic control telescopic oil cylinder or automatically controlled transmission mechanism drive direct current-entire mechanism complexity and bigger deficiency of volume when spraying is changed.
This hydro powered direct current spray conversion device structure is simply compact, easy to operate, dependable performance.Be specially adapted to the fire-fighting operation and need reach the occasion of multiple efficacies such as fire extinguishing, cooling, dilution, protection.
Description of drawings
Fig. 1 is a structural principle schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, the present invention includes nozzle core 1, sealing ring IV2, sealing ring I4, sealing ring II10, sealing ring III12, nozzle 3, pipe joint I5, delivery hose I6, nozzle core frame 7, cylinder body 8, left hydraulic pressure chamber 9, pipe joint II11, right hydraulic pressure chamber 13, fastening bolt 14,3-position 4-way pure water solenoid directional control valve 15, sealing ring V16, sealing ring VI19, delivery hose II17, pipe joint III18, pipe joint IV20, counterbore screw 21, nozzle body 22.
Operation principle of the present invention is as follows:
Before the fire extinguishing operation, whole fire water monitor head is rigidly connected to the exit of fire water monitor barrel by the screw thread of nozzle body 22 ends, constitutes an integral body with fire water monitor.When putting out a fire operation, a press water part that enters water cannon big gun head enters the water inlet P mouth of 3-position 4-way pure water solenoid directional control valve 15 by the X mouth place of nozzle body 22, make 3-position 4-way pure water solenoid directional control valve 15 right-hand member electromagnet DT2 get by the operation control button, the spool that drives 3-position 4-way pure water solenoid directional control valve 15 is to left movement, make water inlet P mouth and the conducting of working hole A mouth, this moment, press water was by delivery hose 6, pipe joint I 5 enters left hydraulic pressure chamber 9, because cylinder body 8 maintains static, therefore nozzle 3 slip of under the hydraulic pressure effect, turning right, simultaneously the hydraulic pressure in the right hydraulic pressure chamber 13 is gone out, by pipe joint II11, delivery hose 17, enter the working hole B mouth of 3-position 4-way pure water solenoid directional control valve 15, and then enter the Y mouth of nozzle body 22 by delivery port T mouth, enter the inner chamber of nozzle body 22, nozzle 3 arrives the spray injection position, electromagnet DT2 power down this moment, the spray injection state of realization water cannon big gun head.
Spray as the direct current that will realize water cannon big gun head, can make 3-position 4-way pure water solenoid directional control valve 15 left end electromagnet DT1 get by the operation control button, the spool that drives 3-position 4-way pure water solenoid directional control valve 15 moves right, feasible water inlet P mouth and the conducting of working hole B mouth that links to each other with the X mouth place of nozzle body 22, press water is by delivery hose 17, pipe joint II11 enters right hydraulic pressure chamber 13, because cylinder body 8 maintains static, therefore nozzle 3 slip of under the hydraulic pressure effect, turning left, simultaneously the hydraulic pressure in the left hydraulic pressure chamber 9 is gone out, by pipe joint I5, delivery hose 6, enter the working hole A mouth of 3-position 4-way pure water solenoid directional control valve 15, and then enter the Y mouth of nozzle body 22 by delivery port T mouth, enter the inner chamber of nozzle body 22, nozzle 3 arrives direct current eject position (position as shown in Figure 1), electromagnet DT1 power down this moment, the direct current spray regime of realization water cannon big gun head.
As long as change the operating position of 3-position 4-way pure water solenoid directional control valve 15 spools by the operation control button, and then change the press water flow in left hydraulic pressure chamber 9 and right hydraulic pressure chamber 13, just can realize that direct current sprays and the automatic steady conversion of spray injection, till fire extinguishing finishes.
