Abstract
The utility model belongs to the technical field of valve control, and discloses a valve electric actuator with a box cover capable of being assembled and dismantled quickly. The valve electric actuator with the box cover capable of being assembled and dismantled quickly comprises a machine body and the box cover arranged on the machine body. The valve electric actuator with the box cover capable of being assembled and dismantled quickly is characterized in that discontinuous grooves are formed in the outer side of a covering opening of the box cover, discontinuous protrusions matched with the grooves are arranged on the inner wall of an upper opening of the machine body, and the box cover and the machine body are connected through the discontinuous grooves and the discontinuous protrusions, wherein the discontinuous grooves and the discontinuous protrusions are combined together in a clamped mode through rotation. The machine body (1) and the box cover (2) are tightened through a screw, the head portion of the screw is in a screw hole of the box cover, the box cover cannot rotate relative to the machine body, and therefore the box cover and the machine body are fixed. A sealing ring is arranged at the joint position of the box cover and the machine body and is a rubber ring or a silica gel ring. According to the valve electric actuator with the box cover capable of being assembled and dismantled quickly, at the time of repair, a worker only needs to loosen the screw and then rotate the box cover about 40 degrees, the grooves in the box cover and the protrusions on the machine body are dislocated, and then the box cover can be dismantled. The valve electric actuator with the box cover capable of being assembled and dismantled quickly is simple in structure, easy to produce and manufacture, low in cost, convenient to operate and high in safety factor.
Description
Technical field
The utility model relates to electric device for valve, is the electric device for valve of a kind of rapid-assembling and quick-detachment case lid specifically, belongs to technical field of valve control.
Background technique
At present the Electric actuator of valve is used very extensively, is no matter that industry, agricultural, national defence are most advanced and sophisticated, or the departments such as communications and transportation, people's lives all need a large amount of, various types of valves.Existing electric valve generally comprises body and is arranged on the body upper box lid.In actual maintenance process, the dismounting case lid need unclamp fixedly several screws of case lid, time-consuming longer, can not satisfy in nuclear island of nuclear power station, coal mine inferior place, require the time-consuming short requirement of trying one's best during the maintenance Electric actuator, as long maintenance operation, may produce the even catastrophic consequence of serious consequence, therefore Security can not be guaranteed, must have a kind of can rapid-assembling and the device of quick-detachment case lid.
The model utility content
The purpose of this utility model is exactly for above-mentioned existing issue, and a kind of simple in structure, rapid-assembling that safety coefficient is high and the electric device for valve of quick-detachment case lid are provided.
The utility model is to realize like this, the electric device for valve of a kind of rapid-assembling and quick-detachment case lid, comprise body and be arranged on case lid on body, it is characterized in that, the lid mouth outside of described case lid is provided with intermittent grooves, body inwall suitable for reading is provided with the intermittent bosses that is complementary with groove, and case lid and body are by intermittent grooves and intermittent bosses rotation engagement connection; Described body and case lid fasten by screw threads.
Described case lid and body joint are provided with seal ring.
Described seal ring is rubber ring or silica gel ring.
The utility model is simple in structure, the manufacturing is easy, cost is low, easy to operate, safety coefficient is high.By the utility model, case lid covers a mouthful outside and is provided with intermittent grooves, and body inwall suitable for reading is provided with the intermittent bosses that is complementary with groove, and case lid is inserted body, rotates case lid, and case lid and body are by intermittent grooves and intermittent bosses rotation engagement connection.Body screws with screw by the screw hole that arranges on it, can prevent effectively that the case lid rotation from coming off; Case lid and body joint are provided with seal ring, play seal action.When maintenance, only need to unclamp a screw, then case lid only need rotate approximately 40 degree, makes groove and the dislocation of the projection on body on case lid, can unload case lid.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of body of the present utility model and case lid screw connection portion position.
1 body, 2 case lids, 3 seal rings, 4 screws in figure.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the structure relevant with the utility model.
Embodiment 1
The electric device for valve of a kind of rapid-assembling and quick-detachment case lid, comprise body 1 and be arranged on case lid 2 on body 1, lid mouth outer installment intermittent grooves at case lid 2, the intermittent bosses that body 1 inwall setting suitable for reading and groove are complementary, case lid 2 rotates engagement connection with body 1 by intermittent grooves and intermittent bosses; The screwing hole is set on case lid 2, on body 1, lower screw hole is set, lower screw hole is rotary with screw 4, and screw 4 heads can prevent effectively that case lid from rotating and coming off in the screwing hole.In case lid 2 and body 1 joint, seal ring 3 is set, seal ring 3 makes that case lid is loosening, the effect of sealing, and the seal ring 3 here is silica gel ring.
Embodiment 2
The electric device for valve of a kind of rapid-assembling and quick-detachment case lid, comprise body 1 and be arranged on case lid 2 on body 1, lid mouth outer installment intermittent grooves at case lid 2, the intermittent bosses that body 1 inwall setting suitable for reading and groove are complementary, case lid 2 rotates engagement connection with body 1 by intermittent grooves and intermittent bosses; The screwing hole is set on case lid 2, on body 1, lower screw hole is set, lower screw hole is rotary with screw 4, and screw 4 heads can prevent effectively that case lid from rotating and coming off in the screwing hole.At case lid and body joint, seal ring 3 is set, seal ring 3 makes that case lid is loosening, the effect of sealing, and the seal ring 3 here is rubber ring.
By above technological scheme, use screw 4 can reach the effect that case lid 2 is fixedly connected with body 1, avoid case lid 2 to rotate and come off, and because screw 4 has and only has one, changed the mode that case lid 2 and body 1 in the past are connected by a plurality of screws, when dismantling case lid 2, only need to unclamp a screw 4, case lid 2 rotates approximately 40 degree, makes groove and the dislocation of the projection on body 1 on case lid 2, can unload case lid 2.When assembling, only need case lid 2 is rotated approximately 40 degree, make groove and the protruding engagement connection on body 1 on case lid 2, simultaneously screw 3 is tightened on lower screw hole and case lid 2 and body 1 can be fixed.And reach seal action by the seal ring 4 that arranges, assurance case lid 2 fully contacts with body 1.
Above specific descriptions; purpose, technological scheme and beneficial effect to model utility further describe; the above is only several specific embodiment of the present utility model; and be not used in and limit protection domain of the present utility model, all any modifications of doing according to spirit of the present utility model and principle thereof, be equal to the row that replacements, improvement etc. all belong to protection domain of the present utility model.
