Portion.
According to an example of the present utility model, between described valve gap and described valve body, it is provided with the second O.
Additional aspect of the present utility model and advantage will part be given in the following description, and part will be from explained below
In become obvious, or recognized by practice of the present utility model.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the check-valves according to one embodiment of this utility model.
Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, the most ad initio
Represent same or similar element to same or similar label eventually or there is the element of same or like function.Below by ginseng
It is exemplary for examining the embodiment that accompanying drawing describes, it is intended to be used for explaining this utility model, and it is not intended that to this utility model
Restriction.
Below with reference to the accompanying drawings describe in detail according to check-valves of the present utility model.As it is shown in figure 1, according to this utility model
A kind of check-valves, including valve body 100, valve seat 200, valve gap 300, flap 400.
Specifically, valve seat 200 is plugged on valve body 100, the valve channel 110 of the axis of valve seat 200 and valve body 100
Axis becomes predetermined angular.Advantageously, described predetermined angular is 3 °～8 °.Further, described predetermined angular is 5 °.
According to check-valves of the present utility model, the axis of valve seat becomes predetermined angular with the axis of the valve channel of valve body, makes
Obtain check-valves can reliably seal or open, simple in construction, dependable performance.
As it is shown in figure 1, flap 400 is located at above valve channel 110, the most described predetermined angular is faced upward.Thus,
When the check valve is closed, flap 400 is to tilt with the sealing surface of valve seat 200, good sealing effect；And when the check valve is opened,
Owing to the axis of valve seat 200 becomes, with the axis of the valve channel 110 of valve body 100, the predetermined angular faced upward, flow through valve channel 110
Medium one impulse force faced upward is provided at valve seat 200, can more preferably wash flap 400 open, improve what check-valves was opened
Reliability.
According to embodiments more of the present utility model, valve body 100 passes through to be weldingly connected with the junction of valve seat 200.Flap
The outer surface of 400 is provided with the first O 410, and the cross section of the first O 410 is T-shaped.Valve gap 300 can by bolt 310
Releasably it is arranged on the top of valve body 100.The second O 320 it is provided with between valve gap 300 and valve body 100.
According to check-valves of the present utility model, simple in construction, good seal performance, open and close reliable.
