Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of a-quadrant in Fig. 1.
Embodiment
Further understand for making to have structure characteristic of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
Fig. 1 and Fig. 2 gives an embodiment of the present utility model, in this embodiment, give a kind of clamp-press type combustion gas ball-valve dedicated, comprise valve body 1, valve ball 2, valve rod 3 and valve handle 4, blast tube 11 is offered in this valve body 1, this valve ball 2 is located in this blast tube 11, between this valve ball 2 and valve body 1, be provided with sealing gasket 8, ensures to have good sealability between valve ball 2 and valve body 1 thus.This valve rod 3 is extended to the outside of valve body 1 by the inside of valve body 1, be provided with seal washer 9 between this valve rod 3 and valve body 1, ensures to have good sealability between valve rod 3 and valve body thus.
One end of this valve rod 3 is connected with valve ball 2, and the other end is connected with valve handle 4.In particular, in the present embodiment, one end that this valve rod 3 is connected with valve ball 2 is provided with screens 31, this valve ball 2 offers the draw-in groove 21 corresponding with screens 31, by the cooperation of draw-in groove 21 on screens 31 on valve rod 3 and valve ball 2, can realize valve rod 3 with valve ball 2 in axial flexible connection, be fixedly connected with in circumference, also namely realizing valve ball 2 along with valve rod 3 circumferentially rotates together, but valve ball 2 is not along with the motion of valve rod 3 in the vertical direction; The one end be connected with valve handle 4 at valve rod 3 is provided with connecting screw 7, correspondingly on this valve handle 4 and valve rod 3 is provided with the attachment hole 71 matched with connecting screw 7, namely realizes valve handle 4 and valve rod 3 is fixedly linked by connecting screw 7.Therefore in the present embodiment, just can realize driving valve ball 2 to rotate by rotating valve handle 4, thus can realize regulating the aperture of ball valve.
Valve body 1 is provided with valve gap 5, this valve gap 5 is provided with the gas passage 51 be connected with blast tube 11, and this valve gap 5 extends outward and forms clamp-press type sleeve pipe 6, and the middle part of this clamp-press type sleeve pipe 6 is provided with U-type groove 61, be provided with seal ring 62 in this U-type groove 61, sealing circle 62 is O type rubber seal.Thus realize, the utility model is in installation process, the gas pipeline of stainless steel is inserted in clamp-press type sleeve pipe 6, and carry out the operation of card pressure with the card splenium position of special card press tool to U-type groove 61 and U-type groove 61 one or both sides simultaneously, make clamp-press type sleeve pipe 6 and the gas pipeline contraction deformation simultaneously of card splenium position, clamp-press type sleeve pipe 6 after distortion and gas pipeline are the mechanism that centre is little, two is large, therefore can resistance to plucking be realized, also namely realize clamp-press type sleeve pipe 6 and gas pipeline to carry out axial restraint; Clamp-press type sleeve pipe 6 after card compressive strain simultaneously and gas pipeline are that cross section is squeezed into hexagon, therefore can anti-rotation be realized, also namely realize clamp-press type sleeve pipe 6 and gas pipeline being carried out radial direction to fix, be to sum up, clamp-press type sleeve pipe 6 can be realized to be fixed on gas pipeline by the operation of card pressure, also namely realize ball valve to be fixed on gas pipeline.In addition, seal ring 62 in U-type groove can radially shrink in extruded process to be held tightly, to reach the object of leakage sealing, thus make, between clamp-press type sleeve pipe 6 and blast tube, there is good sealability, therefore the utility model have that easy for installation, reliability is strong, environmental protection and practical advantage.
Simultaneously, in the present embodiment, positioning step 52 is provided with in valve gap 5, this positioning step 52 is used for positioning the stainless steel gas pipeline extend in clamp-press type sleeve pipe 6, thus can realize, on the one hand, simplify installation to spend in comfort, operating personnel only needs to be set on gas pipeline by clamp-press type sleeve pipe 6 along gas pipeline, until blocked can not, deeply, now just can ensure to carry out the operation of card pressure between clamp-press type sleeve pipe 6 and gas pipeline normally by positioning step 52; On the other hand, block the continuation of stainless steel gas pipeline deeply by positioning step 52, thus can avoid because stainless steel gas pipeline strikes valve ball 2, and the situation causing ball valve to damage occurs.To sum up namely, the utility model has easy for installation, that reliability is strong and practical advantage.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
