Abstract
The utility model relates to a material angle valve with a flexible connecting valve core. The material angel valve comprises a valve body, a valve seat, a valve rod and a valve core, wherein the valve seat is arranged on the valve body; the valve core is arranged at the bottom end of the valve rod; the upper section of the valve rod is arranged in the valve body; the bottom end part of the valve rod is integrally and fixedly connected with a bumping of the valve rod; the outer diameter of the bumping of the valve rod is larger than the outer diameter of the valve rod; the bottom end surface of the bumping of the valve rod is of a spherical surface; a mounting cavity is arranged in the valve core; moreover, the valve core is also provided with a gland nut; the gland nut is sheathed outside the valve rod, and is based on the bumping of the valve rod; the bumping of the valve rod and the gland nut are together arranged in the mounting cavity; and the gland nut is integrally fixed with the valve core through a set screw. As the valve core flexible connecting technology is adopted, the sealing performance of the valve can be greatly improved. As the valve core flexible connecting technology is adopted, the processing precision and the assembling precision demand of the valve core and the valve rod are all reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of material angle valve, and especially a kind of have a material angle valve that flexibly connects spool.
Background technique
Along with improving constantly of domestic industry automatization level, modulating valve is as the most frequently used in the process control, most important final controlling element, its overall development speed is very quick, material angle valve is no exception, but the switching mode material angle valve in a lot of petrochemical equipments all requires zero leakage, and most of material angle valve is rigidly connected because of the Placement between spool and the valve rod all adopts in the existing technology, sealability just was difficult to satisfy the requirement of zero leakage after spool repeatedly moved, and the installation precision that is rigidly connected is had relatively high expectations, assembling difficulty is bigger, cost of production higher (especially for the bigger valve of specification) therefore is difficult to satisfy the actual conditions demand.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can be by a relatively large margin raising material angle valve seal spool performance, spool has good self-regulation, requires lower having to flexibly connect the material angle valve of spool to processing, installation precision.
The technological scheme that provides according to the utility model, described have a material angle valve that flexibly connects spool, comprise valve body, valve seat, valve rod and spool, valve seat is installed on the valve body, spool is installed on the valve rod bottom, the epimere of valve rod is installed in the valve body, one is fixedly connected with the valve rod projection in the bottom of valve rod, the external diameter of described valve rod projection is greater than the external diameter of valve rod, and the bottom end of valve rod projection is a sphere, offers the installation cavity in the described spool, also be provided with gland nut, gland nut is enclosed within the outer also seat of valve rod on the valve rod projection, and the valve rod projection is put into together with gland nut cavity is installed, and gland nut and spool are fixed as one by Cock screw.
Also comprise upper connecting base plate and lower connecting base plate, the upper connecting base plate is fixed on the valve body, fix by locking screw between upper connecting base plate and the lower connecting base plate, valve seat is fixed on the valve body by upper connecting base plate and lower connecting base plate, between upper connecting base plate and valve body and lower connecting base plate and valve seat be equipped with seal washer.
Be provided with lining in valve body, lining is enclosed within the valve rod outside, is provided with some groups of stuffing box packing in the valve body above lining.
The utility model can increase substantially the sealability of valve owing to adopt spool to flexibly connect technology; The utility model is owing to adopt spool to flexibly connect technology, and the machining accuracy of spool, valve rod, assembly precision require all to decrease, and enhance productivity; The utility model is owing to adopt spool to flexibly connect technology, and spool, valve rod modular design can reduce produces and the bigger valve of maintenance cost, especially latus rectum.
