Arm etc. forms, and drives the rotation of hemisphere face valve element to open by driving the rotation of connecting lever, realizes valve opening and closes valve.
Washed away by flyash, the surface of dome valve plate, which can be gradually worn out, causes sealing property to decline, it is therefore necessary to increases
The anti-wear performance on its strong surface；In addition, in current dome valve, valve body, hemisphere face valve element are all fixed structure, once hemisphere face
Valve element needs that when changing whole dome valve can only be changed, and cost is big, cumbersome during work consuming
For problem above, the utility model makes further research.
Utility model content
For above-mentioned deficiency of the prior art, the utility model provides a kind of assembly type dome valve, can be convenient
The replacing of hemisphere face valve element is carried out, while spool face wearability is good.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals.
Assembly type dome valve, including valve body, the hemisphere face valve element in valve body, for driving hemisphere face valve core rotation

Capsule, valve element mounting seat is provided with the lower valve body, the valve element mounting seat is provided with the first magnet, is provided with the hemisphere face valve element
Second magnet attracting with the first magnet；The valve element mounting seat is connected by connecting shaft with driving connecting lever.
In the application, upper valve body and lower valve body can depart from, and can then remove the hemisphere face valve element of magnetic-adsorption, very
It is convenient.
Preferably, the surface of the hemisphere face valve element is provided with wearing layer, further, the wearing layer increases for nanometer
Tough ceramic layer or hard alloy layer, the purpose of wear-resisting spool face, resistance to high temperature oxidation, resistance to deformation is realized, improve life of product.
Preferably, first magnet is connected with expansion screw, screw of the expansion screw in valve element mounting seat
In, one end of expansion screw is provided with adjusting nut, by rotating adjusting nut, can drive the rotation of expansion screw, realizes
The adjustment of one magnet positions.Make when needing to remove hemisphere face valve element, can first rotate adjusting nut, make the first magnet and the second magnetic
Body separates a certain distance, then can more easily remove hemisphere face valve element.
Preferably, second magnet is located on the installing plate in hemisphere face valve core cavity, the first magnet and the second magnetic
Body is all discoideus magnet.
Preferably, the outer rim of the hemisphere face valve element is stuck on the protuberance of valve element mounting seat, installation rear stability is high.
Compared with prior art, the utility model has the advantages that：A kind of assembly type dome valve is provided, is torn open
The replacing of hemisphere face valve element can be easily carried out after valve opening body, while hemisphere face spool face is provided with wearing layer, realizes valve plate
The purpose of wear-resisting, resistance to high temperature oxidation, resistance to deformation, it is integrally improved the service life of dome valve.
Brief description of the drawings
Fig. 1 is side cutaway view of the present utility model.
Fig. 2 is decomposing schematic representation of the present utility model.
Fig. 3 is side view of the present utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Reference picture 1 is to Fig. 3, assembly type dome valve, including valve body 2, the hemisphere face valve element 3 in valve body 2, for driving
The driving connecting lever 11 that dynamic hemisphere face valve element 3 rotates, the valve body 2 include upper valve body 21 and the lower valve fitted together by bolt
Body 23, the upper valve body 21 are provided with valve port 211 and pressure bladder 212, valve element mounting seat 4 are provided with the lower valve body 23, should
Valve element mounting seat 4 is provided with the first magnet 6, and second magnet 7 attracting with the first magnet 6 is provided with the hemisphere face valve element 3；Institute
State valve element mounting seat 4 by connecting shaft 12 with driving connecting lever 11 to be connected, driving connecting lever 11 is externally provided with housing 1.
In present embodiment, the surface of the hemisphere face valve element 3 is provided with wearing layer, and the wearing layer is nanometer toughening ceramic
Layer or hard alloy layer, realize the purpose of wear-resisting, resistance to high temperature oxidation, resistance to deformation.First magnet 6 is connected with expansion screw 5,
For the expansion screw 5 in the screw in valve element mounting seat 4, one end of expansion screw 5 is provided with adjusting nut；Second magnet
