Abstract
The utility model discloses a water drainage valve of a radiator water chamber. The problems that the conventional water drainage valve of the radiator water chamber is inconvenient to process and a potential safety hazard exists are mainly solved. The water drainage valve is characterized in that a mounting hole (3) is in a step shape with a small interior and a large exterior; the edge of the mounting hole (3) at one end of an inner wall of the water chamber (1) is provided with an annular boss (4); a spiral groove (5) is formed on an inner wall of the annular boss (4); a spiral piece (6) matched with the spiral groove (5) is arranged on the water drainage valve (2); a sealing ring (7) is arranged on an outer wall of the water drainage valve (2); and a guide hole (8) communicated with the mounting hole (3) is formed in the water chamber (1). According to the water drainage valve, with the adoption of a spiral clamp design, a drainage hole is formed, the water chamber and the water drainage valve can be demolded at a time during injection molding, manufacturing processes are effectively reduced, the production is convenient, and the potential safety hazard is eliminated.
Description
Technical field
The utility model relates to a kind of automobile water radiator, is specifically related to a kind of radiator hydroecium discharging valve.
Background technique
Radiator is one of important components in the automobile engine system, and the radiator hydroecium is the critical component on the radiator, and discharging valve is the common mechanism on the hydroecium.Radiator hydroecium and discharging valve are injection molded with plastic mould; The discharging valve that adopts at present all is the thread type structure, is combined shown in Figure 2ly by Fig. 1, when discharging water or exit, directly turns on plug screw and gets final product; But the indoor hot water of emitting of radiator water is easy to scald hand when opening; Have potential safety hazard, in producing radiator hydroecium process, the injection moulding worm structure is very inconvenient in addition; The radiator hydroecium that molding and forming is come out can bring out the threaded insert in the mould, and screwing down threaded insert to put back to instrument again increases labour cost so repeatedly.Therefore be badly in need of occurring lower, convenient for production, the safe in utilization radiator hydroecium discharging valve mechanism of a kind of cost.
The model utility content
In order to solve the problem that existing radiator hydroecium discharging valve is processed inconvenience and had potential safety hazard; The utility model provides a kind of radiator hydroecium discharging valve, and this radiator hydroecium discharging valve adopts the spiral card design, has increased conduction hole; Hydroecium and discharging valve can the disposable demouldings when injection moulding; Reduce manufacturing process effectively, be convenient to produce, also eliminated potential safety hazard simultaneously.
The technological scheme of the utility model is: a kind of radiator hydroecium discharging valve comprises hydroecium and discharging valve; Hydroecium is provided with the mounting hole of inserting discharging valve; Mounting hole is inner small and outside big stepped, and the mounting hole edge of hydroecium inwall one end is provided with annular boss, and the inwall of annular boss is provided with spiral chute; Discharging valve is provided with the screw piece that matches with spiral chute, and the outer wall of discharging valve is equipped with seal ring; Hydroecium is provided with the pod apertures that communicates with mounting hole.
The end of described discharging valve is provided with catch.
The aperture that described mounting hole matches with seal ring is divided into two sections, and less near one section internal diameter of annular boss, another section internal diameter is bigger.
The utlity model has following beneficial effect:, when discharging water, outwards screw out discharging valve owing to take such scheme; Seal ring moves to the cooperation section of mounting hole outside; Water in the hydroecium flows out through pod apertures, because seal ring still is in sealing state with the section of cooperation of mounting hole outside, water can be from the knob end ejection of discharging valve; Can the people not scalded, safe and reliable.In addition, the screw piece of spiral chute on the annular boss of hydroecium and discharging valve outer wall can the disposable demoulding when injection moulding, has reduced manufacturing process effectively, is convenient to produce.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Combine shown in Figure 4 by Fig. 3; A kind of radiator hydroecium discharging valve comprises hydroecium 1 and discharging valve 2, and hydroecium 1 is provided with the mounting hole 3 of inserting discharging valve 2, and mounting hole 3 is inner small and outside big stepped; Mounting hole 3 edges of hydroecium 1 inwall one end are provided with annular boss 4; The inwall of annular boss 4 is provided with spiral chute 5, and discharging valve 2 is provided with the screw piece 6 that matches with spiral chute 5, and the outer wall of discharging valve 2 is equipped with seal ring 7; Hydroecium 1 is provided with the pod apertures 8 that communicates with mounting hole 3.Owing to take technique scheme, when discharging water, outwards screw out discharging valve 2; Seal ring 7 moves to the cooperation section of mounting hole 3 outsides; Water in the hydroecium 1 flows out through pod apertures 8, because seal ring 7 still is in sealing state with the section of cooperation of mounting hole 3 outsides, water can be from the knob end ejection of discharging valve 2; Can the people not scalded, safe and reliable.In addition, the screw piece 6 of spiral chute 5 on the annular boss 4 of hydroecium 1 and discharging valve 2 outer walls can the disposable demoulding when injection moulding, has reduced manufacturing process effectively, is convenient to produce.
Combined shown in Figure 4ly by Fig. 3, the end of described discharging valve 2 is provided with catch 9.Catch 9 plays the axial limiting effect, avoids discharging valve 2 directly to deviate from.
Combined shown in Figure 4ly by Fig. 3, the aperture that described mounting hole 3 matches with seal ring 7 is divided into two sections, and less near one section internal diameter of annular boss 4, another section internal diameter is bigger.When discharging valve 2 screwed in fully, seal ring 7 matched with mounting hole 3 internal diameters near annular boss 4, and seal ring 7 is compressed, and voltage endurance capability is high, can make hydroecium 1 sealing effectively; When draining, discharging valve 2 screws out, and seal ring 7 still is in sealing state with the section of cooperation of mounting hole 3 outsides, and at this moment, hydraulic pressure is by pod apertures 8 releases, and the seal request of seal ring 7 is lower, but can avoid hot water to leak from here, and is safe and reliable.
