Abstract
The utility model provides a combiner device among water supply equipment is equipped with the combiner that is connected through the companion flange with the feed water inlet, and the rear end is equipped with the filter screen in the valve body of combiner, and the front end is equipped with the case, and valve body upper portion is equipped with the automatic blow off valve valve air relief, and the valve body lower part is equipped with automatic wash -out valve. Combiner device among water supply equipment after the improvement, complete equipment have automatic gassing, automatic sluice and self - cleaning combiner filter screen, in time eliminate the function of pipeline pollutant, and equipment overall dimension lessen, takes up an area of the space and reduce, and the price is low, installation and easy maintenance.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to the combiner device in a kind of supply equipment.
Background technology
Backflow preventer, filter are indispensable key equipments in supply equipment.Filter is arranged on inlet pipeline front end, utilizes screen pack by feed water filtration, eliminates the impurity in water supply, ensure that the sanitary condition of water supply, reaches the various valve in protection water supply network and the object of equipment.Backflow preventer is contained in the front end of filter, its function is in power-off, cut off the water supply, prevent under the operating mode of keeping in repair in water supply line for aqueous reflux, avoid refluence water supply pollution water main road.
Backflow preventer in current supply equipment and filter are two products installed separately, and appearance and size is large, trouble when installing and keep in repair.Existing filter apparatus structure is simple, and the impurities adhere in supply channel, on the filter screen of filter, after screen pack can only being disassembled, manually cleans, wastes time and energy, can not reach automatic cleaning, eliminates the object of pipeline contaminants in time.
Summary of the invention
The utility model provides the combiner device in a kind of supply equipment, the shortcoming bothering, can not automatically clean when solving the backflow preventer in background technology, filter installation and keep in repair.
The technical solution of the utility model is achieved in that the combiner device in a kind of supply equipment, be provided with the combiner be connected with feed water inlet by companion flange, in the valve body of combiner, rear end is provided with screen pack, front end is provided with spool, valve body top is provided with automatic blow off valve valve air relief, and valve body lower portion is provided with automatic drainage valve;
Preferably, quantity >=1 of described automatic blow off valve valve air relief.
Preferably, screen pack and filter cotton is provided with in described automatic blow off valve valve air relief.
The beneficial effects of the utility model are: the L combiner device in the supply equipment after improvement, the valve body of L combiner is provided with automatic blow off valve valve air relief, be welded on the top of valve body, automatic drainage valve is welded on the bottom of valve body, a whole set of combiner device has automatic deflation, automatic drainage and automatically cleans the function of combiner filter screen, in time elimination pipeline contaminants, and complete equipment appearance and size tails off, and takes up an area space and reduces, price is low, easy to installation and maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation after the utility model improves.
Part illustrates: 1. automatic drainage valve, 2. companion flange, 3. spool, 4. combiner, 5. automatic blow off valve valve air relief, 6. screen pack, 7, valve body.
Detailed description of the invention
In order to Comprehension and Implementation better, do to make a deposition further to the utility model below in conjunction with accompanying drawing: the combiner device in a kind of supply equipment, be provided with the combiner 4 be connected with feed water inlet by companion flange 2, in the valve body 7 of combiner 4, rear end is provided with screen pack 6, front end is provided with spool 3, valve body 7 upper weld has 2 automatics blow off valve valve air relief 5, is provided with screen pack and filter cotton in automatic blow off valve valve air relief 5, and valve body 7 lower weld has automatic drainage valve 1.
Supply equipment in power-off, cut off the water supply, keep in repair when restarting operation, automatic blow off valve valve air relief 5 is opened, with the screen pack of filtered air and filter cotton in valve body, air enters into pipe-line system by the screen pack of automatic blow off valve valve air relief 5 and filter cotton, air is filtered, avoids the current in the contaminating impurity supply channel in air.
When water work normally runs, the pressure of supply water of water inlet end is higher than the pressure of water side, the spool 3 of combiner 4 is opened under the pressure effect of water inlet end, current in pipeline are smoothly by combiner 4, there is a pressure differential deltap P in the hydraulic pressure in the hydraulic pressure of water inlet end and combiner 4 valve pocket, Δ P >=5KPa, under the effect of pressure reduction, the automatic drainage valve 1 in combiner 4 valve pocket is in closed condition.
Water work in power-off, cut off the water supply, when keeping in repair, the pressure drop of water inlet end, the spool 3 of combiner 4 closes under the action of the spring, and the current of supply channel there will not be the phenomenon flowing back to water main road.
Due to the closure function of spool 3, the pressure drop of water inlet end is zero, the pressure of water side is along with the refluence of building water supply, pressure durations increases, when pressure increase is to more than 8KPa, automatic drainage valve 1 in combiner 4 cavity opens sluicing automatically, flow back to the building water supply of valve pocket reverses through screen pack 6, the impurity being gathered in screen pack 6 utilizes the pressure washing of refluence current to get off, discharged by the automatic drainage valve 1 in valve pocket, play the effect of automatically washing filter screen 6 and supply channel, time saving and energy saving.
The function that a whole set of combiner device has automatic deflation, automatic drainage and automatically cleans, contour size of the unit(s) tails off, and take up an area space and reduce, price is low, easy to installation and maintenance.
