Circle, the ring type seal are ring-shaped rubber sealing ring.
Ring-shaped rubber gasket is equipped between the annular cylinder ear and flange sealing surface.
It is beneficial compared with prior art to have the technical effect that
The utility model by installing filter structure in the channel of the water inlet end of gate valve pipelined channel, filter structure
On the inner surface that circular filter net adverse current is tiltedly mounted on circular cylinder to water inlet port, make larger particles and impurity in water flow and
Under the action of inclined filter screen, majority is concentrated at the inclination angle of the inside, and is opened up axis here and be parallel to filtering wire side
Clean-up port, as long as opening clean-up port, under the action of water flow, these impurity can be all rushed out together with the impurity on inclined surface；Most
Fortunately it when upstream and downstream pipe switch is closed, can also be cleared up with tool, since the axis of clean-up port is parallel filter wire side,
Small-sized hair can also be used to rinse to enter by clean-up port, clear up the sundries being attached on wire side.Generally speaking, the utility model structure
Simply, easy for installation, it is simple and easy to the cleaning of larger particles and impurity, reduce installation and material cost.Suitable for larger
The filtering of particle and impurity.

Specific embodiment
Further explanation is made to the utility model with reference to the accompanying drawing, the utility model embodiment includes but is not limited to
The following example.
As shown in Figure 1, 2, the utility model provides a kind of filter structure and gate valve, and the gate valve includes valve body 1, described
The lumen inner surface of 1 intake tunnel of valve body is equipped with annular stop plate 4, and the filter structure 2 is mounted in intake tunnel, it is preferable that
2 sliding fit of filter structure is socketed in the intake tunnel of the valve body 1, and the water outlet port 207 of the filter structure 2 is held out against
The annular stop plate 4, the filter structure 2 includes circular cylinder 201, annular cylinder ear 202 and circular filter net 205, described
Annular cylinder ear 202 is fixedly connected on the water outlet port 206 of the circular cylinder 201, the anchor ring fitting of the annular cylinder ear 202
On the sealing surface 5 of the 1 intake tunnel end flanges of valve body, the circular filter net 205 is mounted in the circular cylinder 201
It on surface, and is tilted to the circular cylinder 201 water inlet port 206, in itself and table in 201 water outlet port 207 of circular cylinder
Clean-up port I 203 is offered on circular cylinder 201 on the outside of face contact point, is opened up on the lower tube wall of the intake tunnel of the valve body 1
There is clean-up port II 3 and matches connection with the clean-up port I 203 on the filter structure 2.
In order to focus on impurity or larger particles can near clean-up port under the action of water flow, circular filter net 205
To the inclination of water inlet port but water inlet port cannot be exceeded as far as possible against water (flow) direction.
In order to seal and tool disengaging and can make an overall screening the online impurity of circular filter, the clean-up port I at clean-up port
203 and clean-up port II 3 be circular open, form cylindrical channel, the axis of the cylindrical channel is parallel to the mistake
Filtering net surface.
Prevent water from entering gap between 2 barrel outer surface of valve inleting water channel inner surface of tube body and filter device, the ring
The outer surface of the inner port of shape cylinder 201 is equipped with annular groove 204, is embedded with ring type seal in the annular groove 204, excellent
Ring selection shape rubber seal.
In order to be fixed on filter structure 2 more preferably in intake tunnel and guarantee the leakproofness of sealing surface and annular cylinder ear 202,
Ring-shaped rubber gasket is equipped between the annular cylinder ear 202 and flange sealing surface 5.
Working principle, 2 sliding fit of filter structure are socketed in gate valve pipelined channel, and annular cylinder ear 202 is fitted in valve body
On water inlet end sealing surface 5,2 water outlet port of filter structure is held out against in annular stop plate 4, on the circular cylinder 201 of filter structure 2
Clean-up port I 203 to be aligned with the clean-up port II 3 on the tube wall of valve inleting water channel and be connected to and sealed again by silk cap, then, install
The external water inlet line of gate valve water inlet end of filter structure 2, when being mingled with the water flow of larger impurity by tilted circle filter screen 205,
Under the action of water flow and tilted circle filter screen 205, larger particles and impurity majority are concentrated in clear at the inclination angle of the inside
It manages at mouth, then opens clean-up port, under the action of water flow, these impurity can be all rushed out together with the impurity on inclined surface；When
When upstream and downstream pipe switch is closed, is cleared up with tool, since the axis of clean-up port is parallel filter wire side, use small-sized hair
It rinses and is entered by clean-up port, make an overall screening the sundries being attached on circular filter wire side, then gone out in opening upstream switch.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
