Description

Concealed installation faucet valve body

Technical Field

The utility model relates to a tap, in particular to secretly adorn tap valve body.

Background

The water faucet is a common flow control device, and the valve body of most of the existing household water faucets protrudes out of a wall body (namely, is obviously installed), so that the wall surface of a bathroom is disordered, and the attractiveness of the bathroom is influenced. The concealed faucet appears in the corresponding market, the concealed faucet arranges the runner valve body in the wall body, and only the adjusting or control handle and the like are protruded out of the wall body, so that the bathroom wall surface looks simpler. However, most of the concealed faucets on the market have single function, and generally only can realize the control of a single water using device. Although also there are a small number of built-in tap to realize the control to a plurality of water installations, its valve body of this type of tap is rectangular shape mostly, and the whole length of psammitolite is longer, and the inside runner structure is comparatively complicated, and the pouring is difficult.

As shown in chinese patent No. 201621378326.9 entitled four-section three-function concealed thermostatic faucet, three button valve cores are disposed on one side of the thermostatic valve core of the concealed thermostatic faucet, and the on-off of three water paths can be controlled by the button valve cores respectively. As can be known from the attached drawing 1 of the patent, the main body of the concealed constant temperature faucet is formed by integral casting, the mounting holes of the three button valve cores are linearly arranged, the arrangement of the water outlets of the concealed constant temperature faucet is unreasonable, a long distance is reserved between the water outlet of the constant temperature valve core and the rightmost button valve core, and a long flow is needed to communicate the water outlet of the constant temperature valve core and the mounting cavity of the rightmost button valve core. Because the main body of the water faucet is generally formed by metal casting, the runner is formed by placing a sand core in a sand mold in the casting process, and the position of the sand core after pouring is the runner. This secretly adorn thermostatic faucet's valve body is rectangular form, and corresponding runner is also comparatively long and thin, and the psammitolite that is used for forming the runner that then uses during inevitable casting is also comparatively long and thin, and the psammitolite is too long and thin can lead to the psammitolite processing difficulty, and the psammitolite breaks easily in transport, casting process simultaneously, leads to the demand increase of psammitolite to increase the rejection rate of valve body simultaneously, and this can this secretly adorn thermostatic faucet's of greatly increased manufacturing cost. Meanwhile, the flow channel is slender, and the valve body is more difficult to sand after casting.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a secretly adorn tap valve body, its structure is compacter, and the inlet outlet distributes more rationally, can make runner length shorten greatly to reduce the processing degree of difficulty and the manufacturing cost of valve body.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a secretly adorn tap valve body, includes cold water inlet, hot water inlet, mixes the water cavity and a plurality of warm water delivery ports, mixes the water cavity side and is provided with the cold water runner with cold water inlet intercommunication and the hot water runner with hot water inlet intercommunication, has seted up muddy water valve core installing port, characterized by on mixing the water cavity: the water mixing cavity is characterized by further comprising a warm water cavity communicated with the water outlet of the water mixing cavity, a plurality of warm water outlets are formed in the bottom of the warm water cavity, the warm water outlets are close to and transversely arranged on one side of the water mixing cavity, the warm water outlets are respectively communicated with the warm water outlets through the water outlet cavities which are mutually separated, a plurality of switch valve core installing ports used for installing the switch valve core which is arranged at the bottom of the side inlet of the switch valve core are formed in the warm water cavity, the switch valve core installing ports are opposite to the warm water outlets, and the warm water outlets are.
