Valve.
Background technology
After in building water system, family table valve mostly is stop valve and is arranged on water meter at present, when appearance in building water system
Water meter reversing is will result in when cutting off the water, it is easy to damage water meter；And water supply line of registering one's residence all is fitted without filter, shadow at present
The water quality safety of user is rung, when particularly supplied water again after cutting off the water in building water system again, long-range water supply line inwall takes off
The dirt for falling is directly entered water supply line of registering one's residence, and even more affects the water safety of user, and impact people's is healthy.How to make
Make a kind of tap water that can filter and non-return tap water and but also the check-valves of tap water filter net can be convenient for changing as family table valve not only
It is the problem for needing to solve to damage and filter tap water installed in water meter rear defence sealing table.
Utility model content
Technical problem to be solved in the utility model is：A kind of check-valves for being convenient for changing drainage screen are provided.Using this
Check-valves can not only prevent water meter from damaging after being arranged on water meter as family table valve, and can also filter register one's residence in water supply line from
Water, moreover it is possible to the tap water filter net arranged in being convenient for changing the check-valves, improves water meter service life and user's water quality.
This utility model solves the technical scheme of above-mentioned technical problem：A kind of check-valves for being convenient for changing drainage screen, bag
Check valve body is included, the check valve body has water inlet end and water side, non-return valve seat and flap, it is characterized in that：The drainage screen
For cylindrical filtrating screen, the check valve body is sealed on the inwall of water inlet end and affixed stretches out the check valve body side body wall
And to the inclined short tube in water side, the short tube is circular short tube, part of the circular short tube in the check valve body cavity
On be provided with pod apertures, the circular short tube is provided with annulus on the inwall of the end of one end in the check valve body cavity, separately
Equipped with the circular closure coordinated using screw thread, the circular short tube inwall between the annulus and circular closure on the inwall of one end end
On against the cylindrical filtrating screen；The pod apertures are provided with towards on water side one end spherical end surface of the check valve body
Non-return valve seat, the top surface of the flap being used in combination with the non-return valve seat are installed with cursor, the other end of the cursor
Using bearing pin be arranged on the check valve body on the inwall of water inlet end side cavity；
The external diameter of the circular short tube is consistent with the internal diameter of the check valve body, the axis of the pod apertures and the check-valves
The axis of body cavity body is on same vertical plane；
Manhole is provided with the circular closure, the plug coordinated equipped with screw thread on the manhole.
The beneficial effects of the utility model are：It is as this utility model is provided with cylindrical filtrating screen and new in this practicality
The pod apertures of type are mounted with non-return valve seat towards on water side one end spherical end surface of check valve body, are engaged with the non-return valve seat
The top surface of the flap for using is mounted with cursor, and the other end of the cursor has been arranged on check valve body near water inlet using bearing pin
On the inwall of end side cavity.Building are prevented to supply water system after water meter being arranged on using this utility model check-valves as family table valve
The water meter for occurring causing when cutting off the water in system reverses phenomenon generation, solves the problems, such as that water meter is damaged because water meter is reversed, while also
The tap water registered one's residence in water supply line has been filtered, water meter service life and user's water quality has been improve；Simultaneously because this practicality
New circular short tube is provided with annulus, the inwall of other end end on the inwall of the end of one end in the check valve body cavity
The upper circular closure equipped with using screw thread cooperation；Cylindrical shape is against on circular short tube inwall between the annulus and circular closure
Drainage screen.Again supply water to work as after cutting off the water in building water system again and in cylindrical filtrating screen, accumulate more long-range water supply line
When the dirt or cylindrical filtrating screen that inwall comes off needs to change by dirt blocking, circular closure is rotated on circular short tube
Disassemble, the cylindrical filtrating screen arranged in easily having changed this utility model check-valves improves this utility model and stops
Return the service life of valve.
Again due to being provided with manhole in circular closure of the present utility model, the silk that the manhole coordinates equipped with screw thread
It is stifled.When in cylindrical filtrating screen, accumulation has the dirt that long-range water supply line inwall comes off change cylindrical filtrating screen,
Plug is rotated in circular closure and is disassembled, using the pressure of tap water easily by the dirt accumulated in cylindrical filtrating screen
Thing is rinsed well, improves user's water quality.
