Abstract
The utility model relates to an explosion-proof plastic tap, which comprises a valve body and a plastic valve cap, wherein outer screw threads are formed at the top part of the valve body; inner screw threads are formed on the inner wall of the valve cap correspondingly; the valve cap and the valve body are assembled and connected with each other through the inner screw threads and the outer screw threads; a valve core housing is integrally formed on the inner side of the valve cap; the valve core housing downwards extends from the top part of the valve cap to an inner chamber of the valve body; a water outlet is formed on the side surface of the valve core housing; a valve core component internally comprising a valve rod and a ceramic valve piece is installed inside the valve core housing; the upper end of the valve rod penetrates out from the top part of the valve core housing; the valve cap and the valve core housing adopt an integral structure, so that the product structure can be more reasonable, positioning grooves do not need to be formed on the valve core housing and the valve body, and the strength of the valve core housing and the valve body can be ensured; in addition, a user can select and use valve core fittings with reliable quality or specific requirements as required when the explosion-proof plastic tap is assembled, so that different requirements can be adapted to, and the explosion-proof plastic tap is also very simple and convenient to assemble.
Description
Technical field
The utility model relates to a kind of water tap, particularly the explosion-proof type plastic faucet.
Background technique
Market use at present or the water tap of selling generally comprise valve seat, spool and switch knob are formed, the inwall of valve seat upper body is provided with interior tooth, spool is provided with outer tooth, both installations of working in coordination, seal by the O type circle that is enclosed within on the spool, critical pieces such as the valve body spool of this water tap are all made with price higher material such as copper or alloys, and the processing technology complexity of metal parts, make that the cost of product is higher, and use plastic faucet effectively to reduce cost, but the plastic faucet of said structure is when assembling, and spool need be tightened in the housing on valve seat top, add long-term use repeatedly, make the housing of tooth in the band of valve seat top be easy to be burst, shortened the life-span of water tap, in addition, for the higher water tap of some appearance requirement, its shell also can be electroplated processing, and when when adopting said structure, its housing is more prone to aging and breaks.
On the other hand, during existing water tap was produced, mangetic core assembly generally was to dispose separately separately, accessories such as valve core shell, valve rod, ceramic valve plate assembled in advance become whole, only need directly be installed in the valve body and get final product, the assembly quality of valve core shell inside is not easy to control, and also can't satisfy some ad hoc requirement; In addition, also need to be provided with concavo-convex locating slot between mangetic core assembly and the valve body, the intensity of valve body or mangetic core assembly is caused certain influence.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides the explosion-proof type plastic faucet of a kind of simple and convenient, reliable in quality, wide accommodation.
The technological scheme that the utility model adopted is:
The explosion-proof type plastic faucet comprises valve body and plastics valve gap, and described valve body top offers external screw thread, the corresponding internal screw thread that is provided with of valve gap inwall, and valve gap is connected by this inside and outside thread assembling with valve body; The inboard global formation of described valve gap has valve core shell, valve core shell extends downward body cavity from the valve gap top, the side of valve core shell offers water outlet, comprises that the mangetic core assembly of valve rod, ceramic valve plate is installed in this valve core shell, and the valve rod upper end passes from the valve core shell top.
Further improvement of the utility model is provided with seal ring in the described valve gap, and seal ring and valve body external screw thread top form sealing.
Further improvement of the utility model is provided with seal ring between described valve core shell and the valve rod.
Further improvement of the utility model is provided with sealing gasket between described valve core shell lower end and the valve body bottom water inlet, and valve core shell compresses sealing gasket downwards.
Further improvement of the utility model, the top of described valve gap 2 is provided with polygonal boss 24.
The beneficial effects of the utility model are: the valve body top offers external screw thread; the corresponding internal screw thread that is provided with of valve gap inwall; valve gap is connected by this inside and outside thread assembling with valve body; in use; valve gap also has internal radial force to valve body except downward axial force is arranged when tightening, can well protect housing to be not easy to break so in use and leak.On the other hand, because valve gap and valve core shell are monolithic construction, make the more reasonable structure of product, valve core shell and valve body do not need to be provided with locating slot, have guaranteed the intensity of valve core shell or valve body; In addition, in when assembling, the user can select the spool accessory of reliable in quality or particular requirement as required for use, can adapt to different needs, and also very simple and convenient during assembling.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a sectional structure schematic representation of the present utility model.
Embodiment
With reference to Fig. 1, shown in Figure 2, the explosion-proof type plastic faucet comprises valve body 1 and plastics valve gap 2, and valve body 1 top offers external screw thread 11, the corresponding internal screw thread 21 that is provided with of valve gap 2 inwalls, and valve gap 2 is connected by these inside and outside thread 21,11 assemblings with valve body 1; Valve gap 2 inboard global formations have valve core shell 22, valve core shell 22 extends downward body cavity from valve gap 2 tops, the side of valve core shell 22 offers water outlet 23, the mangetic core assembly that comprises valve rod 31, ceramic valve plate 32,33 is installed in this valve core shell 22, and valve rod 31 upper ends pass from valve core shell 22 tops.When producing, only need valve rod 31, ceramic valve plate 32,33 are packed in the valve core shell 22, valve gap 2 is tightened against external screw thread 11 outside get final product again, assemble simply the reliability height.
Be provided with seal ring 4 in the valve gap 2, seal ring 4 forms sealing with valve body 1 external screw thread 11 top 12, and anti-sealing spills from valve gap; Similarly, be provided with seal ring 5 between valve core shell 22 and the valve rod 31.
Be provided with sealing gasket 6 between valve core shell 22 lower ends and the valve body 1 bottom water inlet, valve core shell 22 compresses sealing gasket 6 downwards, and the water that enters valve pocket can only be entered from the ceramic valve plate of bottom.
