As further improving, seal receptacle and lower copper sheathing, the sealing gasket sealed is installed between seal receptacle and regulator board.At seal receptacle and lower copper sheathing, the sealing gasket sealed is installed between seal receptacle and regulator board, seal degree can be strengthened, effectively avoid water to be flowed such as key inner chamber by seal receptacle and lower copper sheathing, space between seal receptacle and regulator board, key inner chamber is made to have water all the time, even with drain valve, water is discharged key, make drain valve freeze when winter, not only waste water resource, and affect the overall performance of fire hydrant.
During work, on pull bar, spring is in compressive state, owing to spring is in compressive state, so being tight seal shape body between seal receptacle and lower copper sheathing, draining bar and connecting plate are directly provided with spring, so, draining bar, spring just form an overall structure by pull bar and connecting plate and seal receptacle, regulator board.When seal receptacle, regulator board are subject to external force driving and move, draining bar also moves, and seal receptacle is also equipped with pull bar, and pull bar one end connects with the key bottom near water inlet elbow, and namely pull bar lower end connects with water inlet.The pull bar other end connects with the key top buckling outlet and air entry, that is pull bar upper end connects with outlet and air entry, but drain valve bottom is communicated with the external world by key, so, drain valve and key are just opened by the isolation of draining bar, form 2 chambers.When driving pull bar to move down by driving device, due to water inlet pipe pressure effect, regulator board and draining bar move down therewith, but seal receptacle is motionless, drain valve lower chamber space is gradually reduced, and touches with drain valve bottom connection, due to the compression force of spring on draining bar bottom draining bar, it is formed for sealing bottom draining bar and bottom drain valve, it is prevented that water is by drain valve stream to outside.Meanwhile, regulator board moves down, and makes part water enter key inner chamber by the space between regulator board and seal receptacle, the pressure suffered by seal receptacle and pull bar is made to diminish, when continuing to move down pull bar, seal receptacle and lower bolt are opened, and the water in water inlet is outwards supplied water by key, outlet.Now this fire hydrant is in opening.
When driving pull bar to move up by driving device, seal receptacle moves together with regulator board, when seal receptacle moves to and contacts with lower copper sheathing, seal receptacle no longer moves, regulator board continues up, hereafter draining bar just setting in motion, regulator board is wanted to contact with seal receptacle, under the compression force of pull-rod spring, regulator board and seal receptacle and lower copper sheathing are formed and seal, draining bar is opened, water retention in water inlet only supplies water to key, on key inner chamber drain valve, the water of part flows out outside key by the gap between drain valve and draining bar, the water of remainder continues to stay key intracavity, now this fire hydrant is closed.
Additionally, owing to spring is in compressive state, so being tight seal shape body between seal receptacle, connecting plate, pull bar and lower copper sheathing, when external force collision is on key, crashproof dish ruptures, and crashproof connector is from middle weak point door fracture under the effect of a pushing out ring, and upper bolt separates with key, but seal receptacle is strained under the counteracting force of spring-compressed on pull bar, and lower copper sheathing tight seal.Effectively stop the outflow of water, during maintenance, only need to change crashproof dish and crashproof connector.
In sum, adopt the fire hydrant of this structure, rational in infrastructure, function antifreeze, crashproof, pressure regulation can be realized, and easy to operate, it is adapted at various water supply occasion and uses, be favorably improved reliability of water supply.
