Description

Valve special for water heater

The utility model relates to a kind of and the matching used Low pressure valve of fast water heater.

The use of fast water heater (gas water-heater and the electric water heater that comprise coal gas, liquefied petroleum gas (LPG)) at present is more and more general, burrows, draws and establish water pipe or leather hose but hole on must the wall in resident family when it is installed.Particularly when kitchen and toilet all will be provided with hot water outlet, required pipeline was more.This had both influenced indoor clean and tidy, attractive in appearance, had wasted many pipelines again.Simultaneously, when in the toilet, using hot water, because that the switch of hot water, be regulated controlled water flow in another room is very inconvenient.Change the cooperation that the hot-water line mounting type needs special valve, existing valve is all undesirable.

Task of the present utility model be for water heater installation, use a kind of new special valve be provided, the entery and delivery port of water heater can be concatenated in user's the water supply pipe system go, become a subloop.This valve can end the former path of tap water at any time, in the middle of this subloop is concatenated into, thereby makes the interior all water taps of user's suite all become the water outlet of water heater; Otherwise this valve can block the water heater subloop again at any time, and the former water route of tap water is connected, and does not influence the use of tap water.Simultaneously, this valve preferably also has " subluxation " function, running water pipe road junction and hot-water line road junction respectively can be closed a part, is opened a part, the hot water or cold water is mixed flow into the rear pipeline.

For achieving the above object, the application provides a kind of Low pressure valve, offer four passwaies on its valve body: two main passage mouths are corresponding with running water pipe, and its bore can be consistent or approaching with the domestic running water mouth of pipe in most of cities footpath, in the time of generally can be by 15mm(1/2) setting.Two subaisle mouths are corresponding with the fast water heater entery and delivery port in addition, general optional 9-14mm bore (the water heater model is more, and the setting of its entery and delivery port is also inconsistent, and subaisle mouth bore is not necessarily in full accord with it).The passway is provided with rib-loop and necessary coupling (for example reducer union) routinely.Spool and driving mechanism are set in the valve body, and the latter also is a routine techniques, can be forms such as handwheel, handle or spanner.Said valve body also can comprise accessories such as valve gap.One of the following scheme that is set to of spool:

A. cock on the position corresponding with the passway, is provided with valve plate, and the cock both sides are divided into two through holes;

B. the ball core is provided with valve plate on the position corresponding with the passway, and both sides are divided into two through holes or two holes are set on the ball core, and its both ends open is corresponding with four passwaies respectively.

C. plunger, promptly to push away, to spur the spool of making switch, this plunger generally has two kinds of working staties, i.e. two positions.When first kind of position, on the cross section of two main passage mouths of corresponding valve body, a port hole is set; When second kind of position, two through holes are set on the cross section of corresponding four passwaies: the respectively corresponding main passage mouth in the two ends of every through hole and a subaisle mouth.

The mounting type that the design and fast water heater are new cooperates, can make the water pipe of water heater become a subloop in user's water supply pipe system, be that the former passage of running water pipe is ended by this special valve, (tap water connects the water heater water intake in the entery and delivery port serial connection inlet pipe road with water heater simultaneously; The water heater water outlet meets the water supply pipe system of a whole set of house), this special valve can be connected the main passage at any time, and subaisle ends, and the instant heating hydrophone is not worked, and tap water is as usual; Otherwise the main passage is blocked, and subaisle is connected, and makes all water taps of resident family all become the water heater water outlet, uses very convenient.Changed like this when water heater is installed to hole on the wall, the indoor phenomenon of establishing several pipelines or leather hose of drawing.When simultaneously this special valve is split into " subluxation ", can make part of running water and hot water enter the rear pipeline simultaneously, avoided the summer tap water to reach maximum, water for bathing is still crossed when scalding, and can only turn down the situation that coal gas is regulated water temperature, can bring into play the maximum effect of water heater, obtain maximum current.Use this special valve that water heater is installed, also reduced hot water pipe's resistance, the contradiction of tap water pressure deficiency when helping to alleviate high residential building use water heater.

Now be described further with embodiment in conjunction with the accompanying drawings.
