Description

A kind of flashing valve

Technical field

This utility model is related to toilet and manufactures field, more particularly, to a kind of flashing valve.

Background technology

Present intelligent closestool does not all have water tank mostly, and the flashing valve by cistern free is directly realized by flushing function, and such as one Plant cistern free closestool flushing valve (patent No. 201310474738.7) and disclose a kind of opening and closing using solenoid valve control water channel, in fact The flashing valve of existing flushing function.But, there is the toilet of water tank, inside water tank, have certain hydraulic pressure, the blow-off line being connected with water tank Interior water cannot overcome this hydraulic pressure that adverse current occurs, and the flashing valve of cistern free does not have water-retention in itself, and inside does not have hydraulic pressure to limit, row Water in dirty pipeline will flow back in flashing valve in backflow, if things go on like this, is easily damaged the construction of flashing valve, and impact uses Life-span.And the water flowing back carries a large amount of antibacterials, if be used in private portion clearing up functionally, can seriously damage the health of user.

Utility model content

The purpose of this utility model is to provide a kind of flashing valve that can prevent adverse current, solves asking in background technology Topic.

For achieving the above object, this utility model adopts the following technical scheme that

A kind of flashing valve, including valve body, described valve body includes water inlet pipe, and the end of described water inlet pipe is connected with aqueduct, The inwall of the end of described water inlet pipe is provided with snap ring；One end of described aqueduct is connected with described water inlet pipe, and the other end is Sealed end；Described aqueduct is communicated with outlet pipe, is provided with counterflow-preventing core in described aqueduct, described counterflow-preventing core include plug and Spring, one end of described spring props up described plug, and the other end is against described sealed end, the size of described plug and described snap ring It is adapted, and top pressure is on described snap ring.

Preferably, the first positioning pipe extending in oriented described aqueduct is connected on described plug, described first positioning The size of the size of pipe and described aqueduct is adapted.

Preferably, described first positioning pipe includes the first locating ring paralleled with described plug, described first positioning Ring is connected on described plug by some connecting rods.

Preferably, the second positioning pipe extending in oriented described water inlet pipe is connected on described plug, described second positioning The size of the size of pipe and described water inlet pipe is adapted.

Preferably, described second positioning pipe includes the second locating ring paralleled with described plug, described second positioning Ring is connected on described plug by some connecting rods.

Preferably, being communicated with cleaning jet pipe on the side wall of described water inlet pipe, the inwall of described water inlet pipe is socketed with and institute State the drainage screen that water inlet pipe size is adapted, described drainage screen covers the water inlet of described cleaning jet pipe.

Preferably, described cleaning jet pipe and described water inlet pipe are vertically arranged.

Flashing valve in this utility model, when not intaking, spring top pressure plug, plug is pressed on snap ring, water inlet Separated by plug between pipe and aqueduct, when water inlet pipe is intake under user control, hydraulic pressure impacts plug, makes spring-compressed, blocks up Head moves into aqueduct, and water enters aqueduct, and is passed in the outlet pipe being connected with aqueduct, realizes flushing function, After water inlet pipe stops water inlet, water inlet inner pipe water pressure reduces, and spring reduces, and again withstands plug, cut-out aqueduct and water inlet pipe Between connection, now stable water pressure in flashing valve, the water in blow-off line cannot by connection outlet pipe adverse current backwash water In valve, more will not enter water inlet pipe it is ensured that stablizing of flushing valve structure, extend the service life of flashing valve.

Brief description

Fig. 1 is the explosive view of this utility model embodiment.

Fig. 2 is the structural representation of this utility model embodiment.

Fig. 3 is the structural representation of valve body 1 in this utility model embodiment.

Specific embodiment

With reference to Fig. 1 to Fig. 3, the technical solution of the utility model is described further, but is not limited to this explanation.

A kind of flashing valve, including valve body 1, valve body 1 includes water inlet pipe 2, and the end of water inlet pipe 2 is connected with aqueduct 3, water inlet The inwall of the end of pipe 2 is provided with snap ring 4；One end of aqueduct 3 is connected with water inlet pipe 2, and the other end is sealed end 5；Water guide Pipe 3 is communicated with outlet pipe 6(for the flushing of defecation), it is provided with counterflow-preventing core 7 in aqueduct 3, counterflow-preventing core 7 includes plug 8 With spring 9, one end of spring 9 props up plug 8, and the other end is against sealed end 5, and the size of plug 8 and snap ring 4 are adapted, and pushes up It is pressed on snap ring 4.

The first positioning pipe 10, the size of the first positioning pipe 10 and the aqueduct extending into aqueduct 3 is connected with plug 8 3 size is adapted, and the first positioning pipe 10 includes the first locating ring 11 paralleled with plug 8, if the first locating ring 11 passes through Dry root connecting rod 12 is connected on plug 8.The second positioning pipe 13 extending into water inlet pipe 2, the second positioning are also associated with plug 8 The size of the size of pipe 13 and water inlet pipe 2 is adapted.Second positioning pipe 13 includes the second locating ring 16 paralleled with plug 8, Second locating ring 16 is connected on plug 8 by some connecting rods 12.The effect of the first positioning pipe 10 and the second positioning pipe 13 is all It is guide-localization, the first positioning pipe 10 is mobile along aqueduct 3 when spring 9 deforms, and the second positioning pipe 13 is when spring 9 deforms So that when plug 8 moves in aqueduct 3, will not offset, situation about blocking will not occur along water inlet pipe 2 is mobile, adopt the The structure of one locating ring 11, the second locating ring 16 and connecting rod 12 so that the first positioning pipe 10 and the second positioning pipe 13 do not have tube wall, In Openworks shape, so, plug 8 is during movement, also without interference with the trend of current, reduces resistance so that current Successfully can flow in flashing valve, realize flushing function.

Cleaning jet pipe 15(is vertically connected with the side wall of water inlet pipe 2 and is used for private portion cleaning function), the inner wall sleeve of water inlet pipe 2 It is connected to the drainage screen 14 being adapted with water inlet pipe 2 size, drainage screen 14 covers the water inlet of cleaning jet pipe 15.General bath Valve, drainage screen 14 will be installed in the water inlet of cleaning jet pipe 15, and water quality is filtered, as soon as the time is long, has miscellaneous in a large number Matter is attached on drainage screen 14, has a strong impact on into water effect and filter effect, so being frequently necessary to take apart flashing valve, cleaning is filtered Net 14, then install back, cumbersome.

In this utility model, cleaning jet pipe 15 is arranged on the side wall of water inlet pipe 2, rather than communicates, so with aqueduct 3 Setting make cleaning jet pipe 15 completely attach to water less than any adverse current, even if because the water of adverse current is likely to enter water guide In pipe 3, also can be shut by plug 8 it is impossible to enter water inlet pipe 2 it is ensured that the water for cleaning function is absolute cleanliness, filter Net 14 covers the water inlet of cleaning jet pipe 15, the impurity in further filter water, and water inlet pipe 2 is vertically arranged with cleaning jet pipe 15, Water, when through water inlet pipe 2, can take away the impurity of adhesion on drainage screen 14, so, is equivalent to each water inlet, all in cleaning Drainage screen 14, it is ensured that the cleaning of drainage screen 14, avoids drainage screen 14 to be replaced as frequently as again.
