Abstract
The utility model design is a disposable injection ball shape water valve, which can substitute the present gate valve with low pressure and stop valve. The strength and sealing performance of the utility model can reach or exceed that of the present ball valve. The utility model includes a valve body, a valve seat, a handle and a sealing ring, characterized in that a connection rod ball 3 is arranged at the middle part of the valve body, and the handle 4 is sleeved at the connection ball 3. The cover cap 5 is directly clamped at the handle 4.
Description
The utility model belongs to valve type, specifically a kind of ball-type water valve.
At present, gate valve, stop valve are rise-fall type and open, opening needs certain space, and the switching time is long, opens the back passing hole and easily stops up, sealing is leaked in being easy to generate, sealing surface causes that easily erosion and friction hinder, and easily gets rusty, necrosis, and intensity, sealability are relatively poor, Heavy Weight, the installation and maintenance inconvenience.And ball valve has certain advantage because of low cost of manufacture on market competition, but shortcoming is that intensity, sealability are relatively poor, and the life-span is short.
The purpose of this utility model then is the problem that exists at above-mentioned prior art, has designed a kind of disposable ball-type water valve that is injection molded into, and it can substitute present low pressure gate valve, stop valve, and intensity, sealability meet or exceed existing ball valve.
The purpose of this utility model can reach by following measure:
A kind of ball-type water valve comprises valve body, valve seat, handle, seal ring, it is characterized in that connecting rod ball 3 is arranged on the valve body middle part, and handle 4 is enclosed within on the connecting rod ball 3, and block 5 directly is connected on the handle 4.
The utility model has following advantage compared to existing technology:
1. be applicable to frequent operation, enable rapid, light.
2. fluid resistance is little, and friction, noise are low.
3. simple in structure, volume is relatively little, and is in light weight, and cost is low, is convenient to maintenance, Never-rusty and non-scaling.
4. good seal performance is several times of metal valve.
5. easy for installation, be not subjected to the restriction of installation direction, MEDIA FLOW is to can be any, and low to the conditional request of medium circulation, the medium that promptly has the suspendible body also can use.
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is designed to one with valve rod and ball, and promptly the connecting rod ball 3, and valve body 1 is all made with strengthening the disposable injection moulding of high molecule plastic with connecting rod ball 3.Handle 4 is a long strip, be enclosed within on the connecting rod ball 3 after the perforation of middle part, the perforation both sides have the immovable point of projection, block 5 directly is connected on the immovable point, valve body 1 advances, outlet end is a hexagon, seal ring 7 is positioned at the left side of connecting rod ball 3 balls, right-hand member, utilize fitting tightly of seal ring 7 and connecting rod ball 3, thereby reach seal action, sealing gasket 6 is arranged on connecting rod ball 3 bodies of rod and is positioned on block 5 bottoms, utilize block 5 handles 4 and sealing gasket 6 block block 5 bottoms and and sealing gasket 6 between generation pretension sealing force, interior pressure is done the time spent, handle 4 and connecting rod ball 3 increase with pressure, thereby keep good sealing.
The open-shut device of ball-type water valve is a porose connecting rod ball 3, and it winds the axis rotation perpendicular to passage, thereby reaches the purpose that opens and closes passage, and this valve mainly supplies the usefulness of opening and closing pipeline and equipment medium.When turning clockwise handle 4, can open valve, the yi word pattern through hole in valve rod ball 3 bulbs communicates with body cavity, and medium can pass through valve; When being rotated counterclockwise handle 4, get final product throttle down, the yi word pattern through hole in connecting rod ball 3 bulbs become with body cavity 90 ° vertical, medium can't pass through valve.
