Description
Technical field
The utility model belongs to one kind for sewage discharge pipeline connector, especially belongs to a kind of for effluent outfall
The clamp connection swing check valve on road.
Background technique
Check-valves currently used for sewage discharge pipeline is mostly flange swing check valve, flange swing check valve, packet
Include valve body, valve seat, flap, rocking bar, flap is towards being provided with rocker shaft, the pin shaft being arranged on valve body on the surface of valve body water outlet
Pin shaft is installed, one end of rocking bar is sleeved on pin shaft, the other end is sleeved on rocker shaft and opens and closes flap in hole.This flange rotation
Opening formula check-valves are first is that be related to component more, and cost of manufacture is high, and installation, detachable maintaining difficulty are big, time-consuming and laborious.Second is that flap and valve
Seat position degree be not easy to guarantee, influence sealing effect.Third is that sundries is deposited at valve seat and causes flap can not in sewage sometimes
It closes.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of clamp connection rotations for sewage discharge pipeline to open
Formula check-valves.It can be reduced using the clamp connection swing check valve for sewage discharge pipeline using component, reduce production
Cost, installation, detachable maintaining are convenient, improve installation, detachable maintaining working efficiency；This can also be improved for sewage discharge pipeline
Clamp connection swing check valve sealing effect；Sundries in sewage can also be prevented, which to be deposited at valve seat, causes flap that can not close
Phenomenon occurs.
The technical solution that the utility model solves above-mentioned technical problem is: a kind of clamp connection for sewage discharge pipeline
Swing check valve, including valve body, valve seat, flap, the valve body has water inlet end and water outlet, it is characterized in that: the valve seat
The two sides of vertical center line upper end are provided with pin shaft hole, and the flap use is sleeved in the pin shaft hole of valve seat vertical center line upper end two sides
Pin shaft and the valve seat be rotatablely connected；
The valve inleting water end, water outlet bore be DN50-200, valve inleting water end axis be higher than water outlet axis
Line 10-50 ㎜；
The valve seat is groove and the sealing surface structure that plush copper matches with the sealing surface that the flap seals, which is recessed
Vulcanize rubber sealing surface on the sealing surface of slot, mutually sealing on the flap excircle with the valve seat is on the sealing surface of plush copper
Vulcanize rubber seal, the cross section of the rubber seal is O-shaped；The valve seat is the rubber that vulcanizes on the sealing surface of groove
The O-shaped rubber seal vulcanized on glue sealing surface and the sealing surface that the flap is plush copper is in linear sealing.
The beneficial effects of the utility model are: since the two sides of the valve seat vertical center line upper end of the utility model are provided with pin
Axis hole, the flap are rotatablely connected using the pin shaft and the valve seat being sleeved in the pin shaft hole of valve seat vertical center line upper end two sides.Phase
For the prior art, reduce the use of rocking bar and rocking bar shaft member, falls below reduction cost of manufacture, ensure that flap and valve seat
Position degree, improve sealing effect；The utility model uses clamp connection structure simultaneously, facilitates installation, detachable maintaining, mentions
High installation, detachable maintaining working efficiency.Since the valve inleting water end axis of the utility model is higher than water outlet axis 10-50
㎜；Sundries in sewage is prevented to be deposited at valve seat the phenomenon that causing flap that can not close.
Again due to the sealing surface that the flap and the sealing surface of the valve base sealing of the utility model match for plush copper and groove,
For the valve seat to vulcanize rubber sealing surface on the sealing surface of groove, mutually sealing on the flap excircle with the valve seat is plush copper
Sealing surface on vulcanize rubber seal, the cross section of the rubber seal is O-shaped；The valve seat is on the sealing surface of groove
The rubber sealing surface vulcanized and the O-shaped rubber seal vulcanized on the sealing surface that the flap is plush copper are in linear sealing.It mentions
The high sealing effect of the utility model.
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 attached drawing: 1. valve bodies, 2. valve seats, 3. flaps, 11. water inlet ends, 12. water outlets, 4. pin shafts, 21. grooves, 31. convex
Head.
