Abstract
A severe service resisting fixed type plug valve comprises a valve body, a bonnet, a valve stem and a cock. A sealing filler layer is filled inside a gap between the bonnet and the valve stem, a sealing bush arranged inside the valve body is in movable sealing engagement with the outer wall of the cock, a convex shaft is arranged at the rotary center of the bottom portion of the cock, a cavity is correspondingly arranged at the bottom portion of the valve body, the convex shaft is disposed inside the cavity in rotating engagement so as to from a cock displacement-preventing fixed structure. The bottom portion of the cock of the valve is relatively fixed so as to prevent horizontal deflection under pressure, thereby guaranteeing uniform frictional contact of the sealing bush without easily occurred leakage due to uneven wear, further engagement between the convex shaft and the cavity has certain axial guide function, the cock can be vertically pressed down to maintain reliability of sealing contact after the sealing bush is worn, and therefore, the valve meets sealing requirement for severe service.
Description
Technical field: the utility model relates to a kind of stopcock, particularly is applied to the stopcock of special harsh operating mode.
Background technique: harsh operating modes such as high temperature, high pressure, deep-etching are often arranged in industrial field productions such as chemical industry, pharmacy, and the stopcock of using in its process pipe is very high to the requirement of sealing, must all prevent dielectric leakage in all cases.Usually the cock of stopcock bottom does not contact with valve body, and the cock outer wall utilizes seal cartridge and body cavity motive sealing to cooperate, under the pressure medium effect, and cock meeting slight shift, the wearing and tearing that are easy to cause seal cartridge are inhomogeneous and produce and leak influence production.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of cock can not be shifted, the fixed stopcock of the anti-harsh operating mode of reliable sealing.
The utility model comprises valve body, valve gap, valve rod and cock, be filled with the stuffing box packing layer between valve gap and the valve rod in the space, the outer wall motive sealing that then is provided with seal cartridge and cock in the valve body cooperates, the rotating center place, bottom of cock is provided with protruding axle, the then corresponding cavity that is provided with in valve body bottom, protruding axle places cavity to be rotatably assorted, and constitutes the anti-displacement of cock fixed structure.
Cock of the present utility model bottom relative fixed, can prevent to be offset in the pressure action plane, the rubbing contact that can guarantee seal cartridge is even, be difficult for to produce uneven wear and leak, and the cooperation of protruding axle and cavity also has axial leading role, and after seal cartridge used wearing and tearing, cock can vertically press down, keep sealing the reliability of contact, adapt to the seal request of harsh operating mode.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is embodiment 1 a main structure schematic representation;
Fig. 2 is the schematic representation of the anti-displacement of cock fixed structure;
Fig. 3 is another form figure of Fig. 2;
Fig. 4 is another form figure of Fig. 2;
Fig. 5 is embodiment 2 the anti-displacement of a cock fixed structure schematic representation;
Fig. 6 is another form figure of Fig. 5;
Fig. 7 is another form figure of Fig. 5;
Fig. 8 is another form figure of Fig. 5.
Embodiment 1: as shown in Figure 1, be filled with stuffing box packing layer 5 in the space between valve gap 2 and the valve rod 4, the outer wall motive sealing that then is provided with seal cartridge 6 and cock 3 in the valve body 1 cooperates.The rotating center place, bottom of cock 3 is provided with protruding axle 7, and valve body 1 bottom is sealedly connected with bottom 9, and fixed block 10 is positioned on the bottom 9, and fixed block 10 centers are provided with cavity 8, and cavity 8 is a through-hole form among this figure.The protruding axle 7 of cock 3 places cavity 8 to be rotatably assorted, and constitutes the anti-displacement of cock fixed structure, and this form more easily guarantees coaxality when the anti-displacement fixed structure of processing or assembling cock 3.
In practice, the anti-displacement of cock fixed structure certainly has multiple, and as shown in Figure 2, cavity 8 is located at valve body 1 bottom.As shown in Figure 3, the bottom of valve body 1 is sealedly connected with bottom 9, and cavity 8 is located at the corresponding position of bottom 9.As shown in Figure 4, fixed block 10 is located at valve body 1 bottom, and these fixed block 10 centers also are provided with cavity 8 and protruding axle 7 correspondences.As long as can prevent the skew of cock 3, other similar structure also all is equal to.
Present embodiment also is connected with grease pouring valve 11 at the sidewall of valve gap 2, and this grease pouring valve 11 and stuffing box packing layer 5 place are communicated with, and constitute urgent greasing sealing mechanism.When 5 breakage of stuffing box packing layer, grease gun can carry out temporary sealing by the grease pouring valve 11 urgent seal geases that inject, and prevents leakage contribution production like this.
Embodiment 2: as shown in Figure 5, the rotating center place, bottom of cock 3 is provided with cavity 8, and valve body 1 bottom then correspondence is provided with protruding axle 7, and protruding axle 7 places cavity 8 to be rotatably assorted, constitute the anti-displacement of cock fixed structure, the remaining part structure of present embodiment is substantially with embodiment 1.
Equally, the anti-displacement of the cock of present embodiment fixed structure certainly has multiple, and as shown in Figure 6, the bottom of valve body 1 is sealedly connected with bottom 9, and protruding axle 7 is located at the corresponding position of bottom 9.As shown in Figure 7, valve body 1 bottom also is provided with fixed block 10, and these fixed block 10 centers also are provided with protruding axle 7 and cavity 8 correspondences.As shown in Figure 8, fixed block 10 is positioned on the bottom 9, and fixed block 10 centers are provided with protruding axle 7 and cavity 8 correspondences.
