Summary of the invention
Problem for above-mentioned existence, the utility model relates to a kind of fluid control valve, a kind of reasonable in design be provided, assemble simple and convenient, good sealing effect, the filter screen disassembly, cleaning easily, the filtration stop valve a kind of easy to connect that can directly be connected with the PP-R pipe.
For solving this technical problem, the utility model is taked following scheme: a kind of filtration stop valve easy to connect, comprise valve body, valve gap, valve rod, flap, pressure cap and handwheel, described valve body is provided with the water intake of medium circulation, water outlet and valve port, valve body top and bonnet lower are tightly connected, described flap is loaded on the valve rod lower end and is placed in the valve body valve pocket, and corresponding with valve port, described valve rod upper end is through valve gap and pressure cap, and be connected with handwheel, be provided with filler between valve gap upper inside wall and valve rod, valve gap top and pressure cap are tightly connected, be provided with a packing ring between pressure cap and filler.Described filter screen in the valve body valve pocket between valve seat top and valve gap inside, and pins filter screen by fixing bolt, and described valve body is positioned on two free ends of water intake and water outlet respectively the PPR pipe joint that is tightly connected by the attaching nut.
Further, described a kind of filtration stop valve easy to connect, it is characterized in that: the junction plane of described valve body and valve gap is provided with pad.
Further, described a kind of filtration stop valve easy to connect, it is characterized in that: the junction of described fixing bolt and valve gap inside is provided with seal washer.
By adopting the aforementioned techniques scheme; the beneficial effects of the utility model are: a kind of filtration stop valve component easy to connect of the present utility model are few, assemble simple and conveniently, reduced workman's labor intensity; also greatly reduce cost of production, for enterprise obtains more profit simultaneously; In addition, of the present utility model simple in structure, filter screen disassembly, cleaning or convenience easy to maintenance, when a kind of filtration stop valve easy to connect slightly has damage, do not need integral replacing, can take easily maintenance apart.This novel a kind of filtration stop valve body easy to connect adopts HBb59-1 material brass, is applicable to high temperature media, can not produce any poisonous chemical element, and the healthy of people had very great help.Also has a kind of filtration stop valve easy to connect, its valve body is positioned on two free ends of water intake and water outlet respectively the PPR pipe joint that is tightly connected by the attaching nut, while making this Novel filtration stop valve be connected with the PP-R pipe, only needing hot melt to peg graft gets final product, filter thereby reach the purpose that stop valve directly is connected with the PP-R pipe, rational in infrastructure, simultaneously, valve body adopts the attaching nut to connect the PPR pipe joint, be convenient to disassembled and assembled freely, be provided with Sealing between PPR pipe joint and valve body, make this novel a kind of filtration stop valve sealing effect easy to connect better, more reliable and more stable.
