Abstract

The utility model discloses a new type water faucet valve core, which comprises a valve handle, a water flow controlling part, and a valve core casing body. The lower end of the valve handle is connected with the water flow controlling part, and the water flow controlling part is installed in the valve core casing body; a connecting hole connected with the water pipe is arranged at the lower end of the valve core casing body, and the connecting hole is connected with the water inlet hole on the water flow controlling part. Because a connecting hole connecting the water pipe is arranged at the lower end of the valve core casing body of the utility model and the connecting hole is directly connected with the water pipe, the casting technology of the water faucet casing body is reduced, and the products of good sealing performance, high quality and low cost can be easily manufactured.

Description

Novel faucet valve core

Technical field

The utility model relates to a kind of water tap, particularly relates to a kind of novel faucet valve core.

Background technique

The water tap of commonly using, the spool housing 1 ' that water controlled plate normally will the be housed tap shell 2 ' inner chamber 21 ' of packing into, and between spool housing 1 ' outer surface and tap shell 2 ', put seal ring 3 '.Water pipe then directly is connected in the attachment hole 22 ' of tap shell 2 ' bottom, and the current that flow into from water pipe flow out from the fire hose draught animals 23 ' behind the flow channel of tap shell 2 ' bottom and water controlled plate.The inner chamber of this tap shell 2 ' needs 2-3 core just can cast and forms as the part of flow channel, and casting technique is comparatively complicated, and higher to the quality requirement of foundry goods, foundry goods is easy to generate shrinkage cavity, pore, causes tap shell to leak easily.

The model utility content

The purpose of this utility model is to provide a kind of quality of product height, is tap shell novel faucet valve core easy to manufacture.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of novel faucet valve core, and it comprises valve handle, current control piece, spool housing; The valve handle lower end connects the current control piece, and the current control piece is nested with in the spool housing; Described spool housing lower end is provided with the attachment hole that is connected with water pipe, and this attachment hole is communicated with water inlet on the current control piece.

The attachment hole of described spool housing lower end has the internal thread that can be spirally connected with water pipe.

The internal thread that described water pipe is spirally connected is a metal insert.

The attachment hole of described spool housing lower end is a through hole, offers the draw-in groove that is used for the holding water pipe at the middle part of spool housing, can be with the water pipe holding in attachment hole by the draw-in groove spare that inserts in the draw-in groove.

It is described that to be used for the draw-in groove spare of holding water pipe on spool housing circumferential surface be the flat pins of an intermediate openings.

Described spool housing is made up of upper shell and lower shell body; Upper shell and lower shell body are two parts independently separately, and upper shell can be connected on the lower shell body; Described current control piece is socketed in the upper shell; Offer attachment hole on the lower shell body as the link that is connected with water pipe.

Described spool lower shell body offers positioning port, matches with the convex positioning block of spool upper shell.

Described spool housing is an integral member.

After adopting such scheme, because the utility model is provided with the attachment hole that is connected with water pipe in spool housing lower end, this attachment hole can directly link to each other with water pipe, castability to tap shell requires lower, casting technique is simple, is easier to produce good seal performance, quality height, lower-cost product.In addition, the utility model also can be divided into described spool housing upper shell and two parts of lower shell body, the upper shell that is used to be nested with the current control piece can be made with plastic materials, but and make as the lower shell body metal of link, this had both saved metallic material, had satisfied again and the firm demand that is connected of water pipe.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment

Shown in Fig. 2 A, Fig. 2 B, Fig. 2 C, first embodiment of a kind of novel faucet valve core of the utility model.

It comprises valve handle 1, current control piece 2, spool housing 3.Valve handle 1 lower end connects current control piece 2, and current control piece 2 is nested with in spool housing 3.The lower end of described spool housing 3 is provided with the attachment hole 31 that is connected with water pipe 10, and this attachment hole 31 is communicated with water inlet on the current control piece 2.Described spool housing 3 is an integral member, and the attachment hole of its lower end 31 is for having the interior threaded hole that can be spirally connected with water pipe 10.In order to guarantee the intensity of spool housing 3 and water pipe 10 joints, the metal insert with internal thread is adopted in this joint, forms with plastic injection-moulded then.

Shown in Fig. 3 A, Fig. 3 B, Fig. 3 C, second embodiment of a kind of novel faucet valve core of the utility model.Its structure is the same substantially with first embodiment, its difference is that the attachment hole 31A of described spool housing 3A lower end is a through hole, offer the draw-in groove 32A that can be used for the holding water pipe at the middle part of spool housing 3A, can be in attachment hole 31A by the draw-in groove spare 4A that inserts in the draw-in groove 32A with water pipe 10A holding.The described draw-in groove spare 4A of holding water pipe 10A on spool housing 3A circumferential surface that be used for is the flat pins 4A (as shown in Figure 5) of an intermediate openings 41A, after this flat pins 4A inserts draw-in groove 32A, two shell fragment 42A on it outwards flick, holding can not break away from water pipe 10A on the draw-in groove 101A of the attachment hole 31A inner conduit 10A that inserts spool housing 3A lower end from attachment hole 31A.
