Abstract
The invention relates to a multifunctional water pump valve which comprises an exhaust valve and a safety valve, wherein the exhaust valve is provided with a water inlet pipe, a water outlet pipe and an air exhaust pipe; the safety valve is provided with a water inlet end, a pressure relief end and a water outlet end; the exhaust valve and the safety valve are connected into a whole; the water outlet pipe of the exhaust pipe is connected with the water inlet end of the safety valve; and the interior of the water outlet pipe or the water inlet end is provided with a one-way valve. When the exhaust valve and the safety valve are combined and connected between a water pump and a boiler of a steam electric ironer and the like, the air in a pump casing or a pipeline can be automatically exhausted in the water pumping process of the water pump, and the high-pressure water flow can be generated in short time to supply water to the boiler. The exhaust valve and the safety valve are provided with one one-way valve. When a certain pressure is generated during water pumping, the one-way valve is opened to inject water into the boiler. When the boiler is changed into a cold state from a heat state, and the negative pressure is generated, the one-way valve can prevent the boiler from absorbing water from the water pump and the pipeline, thereby ensuring that the water quantity in the boiler is stable. When the pressure in the boiler exceeds the specified requirement, the pressure can be safely relieved through the self safety valve.

Said safety valve comprises valve seat, and valve seat is the three-way pipe that is the T font, and feed-water end and waterexit end are separately positioned on valve seat upper channel two ends; Pressure relieving end is arranged on valve seat upper channel middle part, is communicated with the valve seat bottom; The corresponding pressure relieving end in valve seat bottom is provided with pressure regulating mechanism, and is provided with the exhaust passage.
The feed-water end of said valve seat is tightly connected through the outlet pipe of first seal ring and valve body; Be provided with one-way valve in the outlet pipe, be crimped with check valve spring between the end face of one-way valve and feed-water end.
Said pressure regulating mechanism comprises safety valve seal ring, safety valve spring, adjusting screw rod and adjusting pole socket, and the safety valve seal ring is slidingly arranged in the valve seat bottom; Regulating pole socket and valve seat lower end is sealedly and fixedly connected; Adjusting screw rod is threaded with regulating pole socket, and stretches into to regulate in the pole socket and be connected with Adjusting ring, and safety valve spring is crimped between Adjusting ring and the safety valve seal ring; The exhaust passage is arranged on valve seat bottom one side.Regulate the pole socket internal fixation and be provided with nut, and be threaded with adjusting screw rod through nut.
The present invention is through making up outlet valve and safety valve; In being applied to products such as steam and dry iron, coffee machine, and when being connected between water pump and the boiler, in the water pump pump process; Can discharge pump case or ducted air automatically, produce high-pressure water flow at short notice and give boiler replenishing water.In addition, is furnished with an one-way valve in outlet valve and the safety valve, when water pump draws water the generation certain pressure; One-way valve opens is water filling in boiler; When boiler by hot when being transformed into cold conditions and producing negative pressure, this one-way valve can stop boiler from water pump and pipeline, to absorb water, and guarantees that the boiler water yield is stable; When the boiler internal pressure requires above regulation, can carry out safety relief through safety valve own.Its compact structure, cost are low, safe in utilization.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Referring to Fig. 1; This multifunctional water pump valve; Comprise the outlet valve that is provided with intake pipe 15, outlet pipe and outlet pipe, and the safety valve that is provided with feed-water end A, pressure relieving end B and waterexit end C, its outlet valve and safety valve link into an integrated entity; The outlet pipe of outlet valve is connected with the feed-water end of safety valve, is provided with one-way valve 2 in the outlet pipe.
Outlet valve comprises valve body 3, spool 1 and exhaust valve spring 16, and valve body is the three-way pipe that is the T font, and the bottom is an intake pipe 15; Top one side is an outlet pipe; The top opposite side is an outlet pipe, and the outlet pipe port is set with valve gap 17, and slides within is provided with spool; Exhaust valve spring is crimped between spool and the valve gap, and valve gap is provided with the exhaust port 18 relative with spool.
