Abstract
An internal-built filling material valve relates to valves used in the pipeline transmission device. The utility model consists of a valve body, a valve rod and a valve core arranged in the valve body, a sealing filing material, a bearing and a bearing seat arranged between the valve body and the valve rod; the utility model is characterized in that the sealing filling material is arranged at the front end of the bearing; a filling material press ring is arranged between the sealing filling material and the bearing; the filling material press ring is provided with a bearing installation ring trough; the bearing and the bearing seat are arranged in the installation ring trough; the external end of the bearing seat is a flange disc typed external end which is fixed to the valve body; the circumference of the flange disc typed external end of the bearing seat corresponding to the filing material press ring is provided with a plurality of screw holes which are internally provided with a filling material press ring adjusting screw. The utility model ensures that the bearing is not affected by the working medium, ensures the sealing filling material arranged at the front end can be adjusted, and is extremely suitable for pipeline application of working medium which transmits the dust, is easy to be crystallized and has corrosion.
Description
Technical field
The utility model relates to the valve that uses in a kind of pipeline feedway.
Background technique
Existing valve usually by valve body, be arranged on valve rod, spool in the valve body, be arranged on the bearing between valve body and the valve rod and the stuffing box packing that is arranged between bearing outer end valve body and the valve rod is constituted.The shortcoming of the valve of this structure is that its bearing is the shape that contacts with working medium, and when the medium of carrying when pipeline is unclean, or working medium is when being dust, and dust granules very easily enters in the bearing, causes bearing to destroy and causes valve stuck.When working medium for can produce the material of crystalline solid the time, also in bearing, form crystallization easily and influence the proper functioning of bearing, or cause damage of bearings; Some have corrosive operation medium also can make bearing destruction and cause valve stuck in bearing.For addressing this problem, present way is that the front end at bearing is provided with a bearing retaining ring, utilize this bearing retaining ring that bearing and working medium are separated, this mode only plays a part certain to the dust-like working medium, can not solve the destruction to bearing of those easy crystallizations, mordant this class permeability working medium.
Summary of the invention
The purpose of this utility model is intended to overcome the above-mentioned shortcoming of existing valve, provides a kind of bearing and working medium are isolated fully to guarantee that bearing is not subjected to the built-in valve of filler of working medium damage.
The formation of the built-in valve of this filler comprises by valve body, be arranged on the valve rod in the valve body, spool, be arranged on the stuffing box packing between valve body and the valve rod, bearing and bearing support, it is characterized in that described stuffing box packing is located at the front end of bearing, between stuffing box packing and bearing, be provided with a filler pressing, described filler pressing has a Bearing Installation annular groove, described bearing and bearing support are installed in this installation annular groove, the outer end of described bearing support is a flange plate type outer end, be fixed on the valve body, on the circumferential position relative of the flange plate type outer end of bearing support, be provided with several screws, in this screw, be provided with the filler pressing adjusting screw rod with filler pressing.Stuffing box packing deadens between working medium and bearing during work, has guaranteed that bearing is not subjected to the influence of working medium and keeps normal operation, thereby has guaranteed the normal keying of spool; The compressing and regulate of stuffing box packing then acts on filler pressing by the filler pressing adjusting screw rod and realizes.
The utility model has the advantages that to have guaranteed also that when making bearing not be subjected to the influence of working medium the stuffing box packing that is located at its front end can regulate, satisfied rotation, two basic operating conditions of sealing of valve rod.The pipeline that is particularly suitable for carrying dust, easy crystallization and having corrosive working medium uses.
Provide embodiment below in conjunction with accompanying drawing.
