Description

Glass fiber reinforced plastic valve well Technical Field The application relates to the technical field of valve wells, in particular to a glass fiber reinforced plastic valve well. Background At present, in the gas pipeline laying engineering, the glass fiber reinforced plastic valve well is widely applied due to the excellent corrosion resistance, high strength and light weight. The existing glass fiber reinforced plastic valve well is usually provided with a pipeline preformed hole with a fixed size on the side wall for penetrating and connecting a gas pipeline. However, the fixed-size reserved holes have obvious defects, and the fixed-size reserved holes are difficult to be suitable for pipelines with different specifications due to large difference of pipeline specifications used by different gas pipeline projects. If the diameter of the pipeline is larger than the reserved hole, the pipeline cannot be normally installed, and only the valve well can be customized again or the reserved hole can be modified destructively, so that the construction cost and the construction period can be increased and the construction efficiency can be reduced. Disclosure of Invention The embodiment of the application aims to provide a glass fiber reinforced plastic valve well, which can solve the technical problem that the preformed holes of the pipeline with the fixed size of the existing glass fiber reinforced plastic gas valve well are difficult to adapt to gas pipelines with different specifications. The embodiment of the application provides a glass fiber reinforced plastic valve well, which comprises a valve well body, wherein the side wall of the valve well body is provided with a pipeline preformed hole, a pipeline installation assembly is arranged at the pipeline preformed hole, the pipeline installation assembly comprises a fixed sleeve and a movable sleeve, the fixed sleeve is fixedly arranged in the pipeline preformed hole in a penetrating manner, the movable sleeve is detachably arranged in the fixed sleeve, and one end of the movable sleeve is provided with a sealing rubber sleeve. Further, a plurality of clamping convex blocks are uniformly arranged on the outer edge of one end of the movable sleeve, which is far away from the sealing rubber sleeve, a positioning guide groove matched with the clamping convex blocks is formed in the inner wall of the fixed sleeve, an annular clamping groove communicated with the positioning guide groove is formed in the inner wall of the inner end of the fixed sleeve, and the clamping convex blocks can be clamped with the annular clamping groove. Further, the sealing ring is fixedly arranged at the outer end of the fixed sleeve, an annular extrusion plate is arranged at one end, close to the sealing rubber sleeve, of the movable sleeve, and when the clamping convex blocks are clamped in the annular clamping grooves, the annular extrusion plate abuts against the sealing ring. Further, a plurality of reinforcing rib plates are uniformly and fixedly arranged at the joint of the fixed sleeve and the valve well body. Further, one end of the movable sleeve is provided with a fixing assembly for connecting the sealing rubber sleeve with the movable sleeve, the fixing assembly comprises a first flange and a second flange, the first flange is fixedly arranged on the movable sleeve, one end of the sealing rubber sleeve is located between the first flange and the second flange, and the first flange is connected with the second flange through a plurality of matched bolts and nuts. Further, the gas pipeline sealing device also comprises a pipe hoop used for fixing the sealing rubber sleeve on the surface of the gas pipeline. Further, a group of handles are symmetrically and fixedly arranged on the annular extrusion. The utility model has the beneficial effects that: The pipeline installation assembly is arranged at the pipeline reserved hole and comprises the fixed sleeve and the movable sleeve, the gas pipeline is fixed through the cooperation of the fixed sleeve and the movable sleeve, and the gas pipeline is sealed by the sealant sleeve, so that the pipeline installation assembly is suitable for a plurality of gas pipelines with different specifications, is not limited to the pipeline reserved hole with fixed dimensions, and can meet the installation requirements of various pipeline specifications by only preparing the movable sleeve with different dimensions by constructors, thereby greatly improving the universality of the glass fiber reinforced plastic valve well and reducing the condition that the valve well is required to be customized again or the pipeline reserved hole is modified due to the change of the pipeline specifications.
