Description

Can hide the flushing valve in the body of wall

Technical field

The utility model relates to a kind of flushing valve, particularly a kind of flushing valve of hiding in the body of wall.

Background technology

At present, the flushing valve of using between domestic hygiene normally is installed in outside the body of wall, be connected with outlet pipe with the water inlet pipe of water system, but raising along with people's living standard, class to interior decoration requires also more and more higher, be exposed to outer advancing, outlet pipe and flushing valve are obviously attractive in appearance inadequately and neat, and take certain space, so that the design and the effect of the whole interior decoration of influence, if existing flushing valve is installed in the body of wall, when core assembly long-time use go wrong after, then can repair or replace component owing to structural reason can not be taken out core assembly.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of and is embedded in the body of wall, does not take up room flushing valve easy to maintenance.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of flushing valve of hiding in the body of wall, comprise bring into, the valve body and the spool assembly of delivery port, the spool assembly is with gland outward, the spool assembly of band gland can be packed into and takes out from the openend of valve body installing hole, and be fixed in the installing hole by the external screw thread of gland and the screw-internal thread fit of valve body installing hole, between the threaded engagement face of described gland and valve body installing hole sealing ring is housed.

Valve body installing hole openend has the annular mud retaining wall that stretches out the valve wall slab installation position; The openend of described valve body installing hole is equipped with trim; Described trim is contained in exceeding on the cylinder with the threaded engagement face of valve body of gland by being threaded.

Wherein, the spool assembly comprises the valve rod of buoyancy aid and top thereof, and valve rod top is elasticly connected with the pressure hand, has cavity to communicate with the valve body delivery port between above-mentioned gland and the buoyancy aid.

The beneficial effects of the utility model are: the spool assembly is positioned in the installing hole of valve body by gland, the spool assembly of band gland can be packed into and takes out from the openend of valve body installing hole, like this, when flushing valve long-time use go wrong after, can split out whole water valve, only open gland, take out core assembly and just can repair or replace component; The water inlet pipe of flushing valve and water system and outlet pipe all can be built in the body of wall, do not take the interior space, add behind the trim more attractive in appearancely, have satisfied the needs of higher level interior decoration; The design of annular mud retaining wall has stayed the space for the further wall surfacing behind the pre-buried flushing valve, makes the metope of having increased be blocked in outside the retaining mud wall, is unlikely the installation that has influence on gland dismounting and trim.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structure chart of flushing valve in the prior art;

Fig. 2 is a structure chart of the present utility model;

Fig. 3 is the disassembled form figure of Fig. 2;

Fig. 4 is another embodiment of the present utility model;

Fig. 5 is another embodiment of the present utility model.

The specific embodiment

With reference to Fig. 1, a kind of flushing valve commonly used between present domestic hygiene, core assembly 2 is housed in valve body 1, core assembly 2 comprises the valve rod 22 of buoyancy aid 21 and top thereof, valve rod 22 tops are elasticly connected with presses hand 23, the pressure hand 23 of push valve core assembly, water enters from valve inleting water mouth 13, flows out from delivery port 14.This kind flushing valve can only be installed in outside the body of wall, its entery and delivery port is connected with outlet pipe with the water inlet pipe of water system respectively, take up room and influence attractive in appearance, if it is installed in the body of wall, then when core assembly long-time use go wrong after, must destroy body of wall and could take out and repair or replace component.

With reference to Fig. 2, Fig. 3, the utility model is with gland 3 outside the spool assembly 2 of prior art, and the size of spool assembly 2 suitably changed, make the spool assembly 2 of band gland 3 pack into and take out from the openend 41 of valve body installing hole 4, gland 3 is threaded with valve body installing hole 4, the spool assembly 2 of band gland 3 is fixed in the installing hole 4, between the threaded engagement face of gland and valve body installing hole sealing ring 5 is housed, prevent that water spills in the valve body, also can adopt sealant tape, reach identical technique effect, should be considered as being equal to

Technical scheme.

Because flushing valve of the present utility model is to be embedded in the wall base substrate, and people can further fit up the wall billet surface usually, for the metope after raising is unlikely to have influence on flushing valve dismounting to gland when keeping in repair, valve body 1 of the present utility model stretches out wall base installation position 11, openend 41 places at installing hole 4 form annular mud retaining wall 12, have so just stayed the space to wall surfacing.Usually the height of retaining mud wall 12 is advisable to be slightly larger than the finishing face thickness.

In order to make the surface of wall of installing behind the flushing valve more attractive in appearance, trim 6 is housed at the openend 41 of valve body installing hole 4.The mounting structure of trim has multiple, can be sleeved on gland 3 cylindricals by being threaded, and as shown, also can be that perhaps the inner hole thread with annular mud retaining wall 12 is connected in the endoporus of gland 3.

In the present embodiment, core assembly 2 comprises the valve rod 22 of buoyancy aid 21 and top thereof, valve rod 22 tops are elasticly connected with presses hand 23, gland 3 extends to always and is pressed on buoyancy aid 21 tops, have cavity 31 to communicate with valve body delivery port 14 between gland 3 and the buoyancy aid 21, when when pressing down hand 23, buoyancy aid 21 sinks like this, water can enter cavity 31, flows out from valve body delivery port 14 again; Perhaps gland 3 can extend to buoyancy aid 21 tops, communicates with valve body delivery port 14 by other parts and structure and realizes the flushing function of flushing valve.

With reference to Fig. 4, Fig. 5, two other embodiment of the present utility model.Form of structure and first embodiment that these two embodiment are core assembly are different, and it is used to realize that the architectural feature of the present utility model purpose is all identical.

Because the technical solution of the utility model goes for the flushing valve of different structure form; when the structure of valve body and core assembly changes; the shape of gland and also should change with the juncture of core assembly; do not enumerate one by one at this, as long as but adopted the described technical scheme of this patent claim just should belong to the protection domain of this patent.
