Abstract
The invention provides a plug cock with a hollow-out structure, and the plug cock with the hollow-out structure reduces weight of the plug cock, saves casting and producing-processing cost and relieves torque of the plug cock. The plug cock comprises a cock body, wherein a hollow cavity is arranged in the middle of the cock body; a side cavity is arranged on the side part of the cock body; a middle hole is formed in the side wall of the cock body; the middle hole communicates with the side cavity; and the middle hole is sealed by a filling part.
Description
Technical field
The present invention relates to a kind of engraved structure cock, it is adaptable to plug valve, it is particularly suited for bore DN300 above heavy calibers
Plug valve.
Background technology
Plug valve is the rotary valve of closure member or plunger shape, is made on passway on valve plug and valve body by being rotated by 90 °
Passway communicates or separates, and realizes a kind of valve being turned on and off, the such as Chinese patent of Application No. 201310123433.1.
The at present cock of plug valve is all the structure using solid cast, and this structure mainly has following 2 defects：
1st, the weight of cock remains high, and casting and processing cost are greatly increased；
2nd, cock own wt weight, valve can increase the unlatching moment of torsion of valve during unlatching, and this directly affects valve
Quality.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency present in prior art, and provide a kind of reasonable in design
Engraved structure cock, mitigates the weight of cock, saves casting and production and processing cost, while mitigating the moment of torsion of plug valve.
The present invention the adopted technical scheme that solves the above problems is：A kind of engraved structure cock, including cock body, its feature
It is：Central cavity is provided with the middle part of described cock body；The sidepiece of described cock body is provided with sidepiece cavity；In described cock body
Mesopore is provided with the wall of side, mesopore is connected with sidepiece cavity, and mesopore is sealed with filling member.
The top and bottom of central cavity of the present invention is arc surfaced, and its width is gradually reduced from top to bottom.
Sidepiece cavity of the present invention is located at the left and right sides of central cavity.
It is two that the present invention is located at the sidepiece cavity on the left of central cavity, setting up and down；Side on the right side of central cavity
Portion's cavity is two, setting up and down.
The side outwardly of sidepiece cavity of the present invention is arc surfaced, and side inwardly is planar shaped.
The present invention compared with prior art, with advantages below and effect：Cavity is provided with sidepiece in the middle part of cock, formation is adopted
With engraved structure, it is ensured that cock pressure-bearing wall thickness, intensity and the use of cock are not affected, so can both meet use requirement, and
The weight of cock can be mitigated, casting and production and processing cost is saved, while the torsion of plug valve after the completion of assembling, can be mitigated
Square.Pressure-bearing wall thickness is chosen according to design standard, it is ensured that the use intensity of cock is unaffected.Cock rotates in valve body
When, the opening and closing moment of torsion of valve can be mitigated significantly.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following examples are to this
Bright explanation and the invention is not limited in following examples.
Referring to Fig. 1～Fig. 3, the present embodiment includes cock body 1.
The middle part of cock body 1 is provided with central cavity 2.The top and bottom of central cavity 2 is arc surfaced, and its width arrived from above
Under be gradually reduced.
The sidepiece of cock body 1 is provided with sidepiece cavity 3, and sidepiece cavity 3 is located at the left and right sides of central cavity 2.It is empty positioned at middle part
Sidepiece cavity 3 on the left of chamber 2 is two, setting up and down.Sidepiece cavity 3 on the right side of central cavity 2 is two, is above divided into
Put.
The side outwardly of sidepiece cavity 3 is arc surfaced, and side inwardly is planar shaped.
Mesopore 4 is provided with the side wall of cock body 1, mesopore 4 is connected with sidepiece cavity 3.Mesopore 4 is sealed with filling member.Mesopore 4
Primarily to casting is convenient, after the completion of casting, the welding of mesopore 4 is blocked by filling member.
Above content described in this specification is only to present configuration example explanation；And, this
The title taken by bright each several part can also be different, what all constructions according to described in inventional idea of the present invention, feature and principle were done etc.
Effect or simple change, are included in the protection domain of patent of the present invention.
