Abstract
The utility model discloses a pressurization opening valve. A piston cover is arranged at one end of a piston body; a pressurization opening is formed on the piston cover; the other end of the piston body is connected with a cylinder body; a piston is arranged in the piston body; a piston rod connected with the piston penetrates through the cylinder body and is connected with a valve rod in a valve body; the valve body is provided with a water outlet, water inlets and a water discharge hole which are communicated with one other; and the stroke of the valve rod is between the water inlets. The pressurization opening valve provided by the utility model has comprehensive functions, exquisite structure and low making cost.
Description
Technical field
The utility model relates to a kind of water valve, relates in particular to a kind of pressurization opening valve that is used for fire protection pipeline.
Background technology
When the wet alarm valve in the fire fighting device moves, need discharge the fire foam of pressured state in the foam accumulator tank by solenoid control, fire foam is through the pipeline flow-direction proportioner, and mixes according to a certain percentage with press water in proportioner and form qualified foam mixing liquid.Such structure needs magnetic valve to start, and reliability and stability are poor, the product structure complexity, and manufacturing cost strengthens.
The utility model content
The technical problems to be solved in the utility model is to realize a kind of have the simultaneously fire foam of pressured state in the control release foam accumulator tank and the valve arrangement of control current.
To achieve these goals, the technical solution adopted in the utility model is: a kind of pressurization opening valve, its piston body one end is a piston cap, piston cap is provided with the pressurization mouth, its other end is connected with cylinder block, be provided with piston in the piston body, the piston rod that is connected with piston passes cylinder block and is connected with valve rod in the valve body, valve body is provided with delivery port, water inlet and discharge opening and leads to mutually, the stroke of described valve rod between the outlet of valve body internal channel, and is provided with back-moving spring between outlet of the valve body internal channel of water inlet and valve rod at water inlet and discharge opening.
Advantage of the present utility model is that complete function, delicate structure, manufacturing cost are little.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model specification and the mark among the figure are briefly explained:
Fig. 1 is a pressurization opening valve arrangement schematic diagram;
Mark among the above-mentioned figure is: 1, piston cap; 2, piston; 3, piston body; 4, cylinder block 5, valve body; 6, pressurization mouth; 7, delivery port; 8, water inlet; 9, discharge opening.
The specific embodiment
Referring to Fig. 1 pressurization opening valve arrangement schematic diagram as can be known, piston body 3 one ends of pressurization opening valve are piston cap 1, piston cap 1 is provided with pressurization mouth 6, pressurization mouth 6 is subjected to influence of hydraulic pressure to promote to be arranged to be provided with piston 2 in the piston body 3, piston body 3 other ends are connected with cylinder block 4, the valve rod that the piston rod that is connected with piston 2 passes in cylinder block 4 and the valve body 5 is connected, valve body 5 is provided with delivery port 7, water inlet 8 and discharge opening 9 and lead to mutually, water inlet 8 and discharge opening 9 are positioned at valve body 5 homonymies, delivery port 7 is positioned at valve body 5 opposite sides, the stroke of described valve rod at water inlet 8 and discharge opening 9 between the outlet of valve body 5 internal channels, piston 2 promotes piston rods motion drive valve rods and blocks the passage of water inlet 8 in valve body 5 during pressurization mouth 6 pressurizeds, at this moment discharge opening 9 and delivery port 7 are communicated with, between outlet of valve body 5 internal channels of water inlet 8 and valve rod, be provided with back-moving spring, when pressurization mouth 6 is not stressed, the anti-valve push rod of back-moving spring makes valve rod block the passage of discharge opening 9 in valve body 5, and at this moment water inlet 8 and delivery port 7 are communicated with.The delivery port 7 of pressurization opening valve connects drench valve, water inlet 8 water receiving pipes, and discharge opening is got rid of remaining liq, during 6 pressurizations of pressurization mouth, compressing back-moving spring, water inlet 8 sealings, delivery port 7 communicates with discharge opening 9, opens drench valve automatically and removes the interior foam of crushed foam jar again.
