Valve, is equipped with non-return component, and non-return component includes connection component, nut clamping ring, nut, non-return valve core, gasket and pre-tightens bullet
Spring, when valve inlet lateral pressure is lower than outlet side, flap is automatically closed under the action of fluid pressure differential, pre-add reset force, real
Existing check function, prevents liquid from flowing backwards, to solve water meter rotation phenomenon caused by pressure oscillation, effective solution is above-mentioned to be asked
Topic.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
Anti-backflow ball valve after a kind of brass table, including valve component and the non-return component being connect with the valve component, institute
Valve component is stated to include valve body, handle, be located at the intracorporal sphere of the valve and valve rod, the non-return component include connection component,
Nut clamping ring, nut, non-return valve core, gasket and preloading spring, the nut pass through the nut clamping ring and the company
Connected components connection, the non-return valve core connect with the preloading spring, wherein the non-return valve core and the preloading spring it
Between be additionally provided with gasket.
Further, the valve component further includes gland, internal tooth lock washer and the nut being located on the upside of the valve body
Further, sealing ring is additionally provided between the connection component and the sphere.
Further, the valve body uses HPb59-1 material, and the sphere uses ZCuZn40Pb2 material.
Further, the preloading spring uses 0Cr18Ni9 material.
Further, the non-return valve core applies precompression by the preloading spring, when non-return sealing surface left end pressure+pre-
When the sum of tight pressing force of the spring is greater than non-return sealing surface right end fluid pressure, non-return sealing surface closure；When liquid is by the non-return
Component right end flows into, and when influent pressure is greater than the sum of preloading spring pretightning force+left end fluid pressure, liquid opens check-valves
Core 13, the non-return valve core 13 are opened.
The beneficial effects of the utility model are: the utility model provides anti-backflow ball valve after a kind of brass table, it is equipped with only
Component is returned, non-return component includes connection component, nut clamping ring, nut, non-return valve core, gasket and preloading spring, works as valve
When import lateral pressure is lower than outlet side, flap is automatically closed under the action of fluid pressure differential, pre-add reset force, realizes non-return function
Can, prevent liquid from flowing backwards, to solve water meter rotation phenomenon caused by pressure oscillation, effective solution water meter measurement is not allowed to ask
Topic.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 valve body, 2 spheres, 3 sealing rings, 4 valve rods, 5 fillers, 6 glands, 7 handles, 8 internal tooths lock washer, 9 nuts, 10
Connection component, 11 nut clamping rings, 12 nuts, 13 non-return valve cores, 14 gaskets, 15 preloading springs.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
In Fig. 1, the direction F is liquid flow direction.
Anti-backflow ball valve after a kind of brass table, including valve component and the non-return component being connect with valve component, valve body group
Part includes valve body 1, handle 7, the sphere 2 and valve rod 4 being located in valve body 1, and non-return component includes connection component 10, nut clamping ring
11, nut 12, non-return valve core 13, gasket 14 and preloading spring 15, nut 12 pass through nut clamping ring 11 and connection component 10
Connection, non-return valve core 13 are connect with preloading spring 15, wherein are additionally provided with gasket between non-return valve core 13 and preloading spring 15
14, valve component further includes the gland 6 for being located at the upside of valve body 1, internal tooth lock washer 8 and nut 9, connection component and sphere 2 it
Between be additionally provided with sealing ring 3.
Specific embodiment as one preferred, valve body 1 use HPb59-1 material, and sphere 2 uses ZCuZn40Pb2 material
Matter.
Specific embodiment as one preferred, preloading spring 15 use 0Cr18Ni9 material.
Working principle of the utility model is: non-return valve core 13 applies precompression by preloading spring 15, when non-return sealing surface is left
When the sum of end pressure+pressing force of the spring is greater than non-return sealing surface right end fluid pressure, it is close to reach non-return for non-return sealing surface closure
