Description
Technical field
The utility model is related to a kind of closed type butterfly valve, belongs to safety valve technical field.
Background technology
The patent of Application No. 200720195576.3 discloses Electromagnetic Fast Safety Gas Shut-off Valve, and the valve is by butterfly
Valve, tractive magnet, drive link, leverage, lock pin, weight and spring etc. are constituted, and are realized and are not needed motor in application
Coal gas is cut off in driving, it is to avoid stop valve can not cut off and produce the hidden danger of major accident have a power failure when, cut off simultaneously
Speed is also faster than electronic stop valve.But when there is electromagnetism cut-out, valve plate easily excessively upset, and upset under the drive of weight
The reason for inertia etc. cause valve plate easily miss it is vertical to closed position；It is valve opening to be located at horizontal direction additionally, due to valve plate
State, it is valve-closed state that valve plate, which is located at vertical direction, therefore the size of valve plate need to be slightly less than the internal diameter of valve body, so could be real
Existing valve plate freely opening and closing in valve body, such a structure is very high to the sealing requirements of butterfly valve, and prior art is in valve body and institute
State and sealing ring is respectively provided with the contact surface of valve plate, such a setting, because two sealing rings are that upward and downward contacts sealing, sealing effectiveness is not
It is good, gas leakage is easily caused, potential safety hazard is brought to production.
Utility model content
Technical problem to be solved in the utility model is to provide one kind and will not excessively overturn, with limit function, simultaneously
Good sealing effect, is difficult the closed type butterfly valve of gas leakage；Further, the utility model provides a kind of sealing with explosion prevention function
Type butterfly valve.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of closed type butterfly valve, includes being hinged with valve plate two ends in the middle part of the valve body of annular, the valve body inner ring, the valve plate
On be connected with drive link for controlling the valve plate to open and close, the valve plate is irregular arc, the top of the valve body inner ring and/
Or bottom is provided with rib, the valve body with being provided with sealing ring on the contact surface of the valve plate, the sealing ring with it is described
Rib is adjacent and is located at the inner side of the rib.
Valve plate is made up of elastomeric material, the elastomeric material be elastic alloy, the elastic alloy include tin-phosphor bronze or
Beryllium-bronze.Atmospheric pressure it is vertical to decomposing force make elastic alloy to circumferencial direction micro stretching, and then make between two sealing rings
With reference to even closer.
Explosion-proof valve is provided with the valve plate.
The material of the sealing ring includes oil resistant rubber or fluorubber.
The irregular arc of the valve plate is S types or is that some projections being randomly distributed are provided with arc valve.
Be provided with pressure sensor on the inside of the valve plate, the pressure sensor is connected with switch board, the switch board and
Explosion-proof valve is connected.
The outer surface profiling of the inner surface of the rib and the valve plate simultaneously mutually agrees with.
A kind of closed type butterfly valve that the utility model is provided, the setting of rib, with limit function, it is to avoid valve plate is in weight
Drive under excessively overturn, and cause the reason for upset inertia etc. valve plate miss it is vertical to closed position, the utility model
Valve plate when closed once it is i.e. reachable vertical to；Valve plate is the setting of irregular arc, and inside and outside atmospheric pressure is to arc
Shape valve plate press, when atmospheric pressure is acted on irregular type valve plate, oblique atmospheric pressure can be analyzed to horizontal direction power and
It is vertical to power, and it is vertical to power may act on sealing ring, when two sealing rings between combination it is even closer, therefore this practicality is newly
Type good sealing effect, is difficult gas leakage, and level of security is high；The setting of explosion-proof valve, makes the utility model have explosion prevention function, further
Strengthen security performance.
