Abstract
The utility model provides a discharge reduction type stop valve. The stop valve comprises a housing, a valve rod, a spring, a valve core, a filter element and a two-way joint, wherein a step is arranged at the lower part of the valve rod, the spring is sleeved at the step, the bottom end of the valve rod is connected with the valve core, the filter element is arranged between the valve core and the housing and the housing is connected with the two-way joint; the housing adopts an integrated structure; a valve plate is arranged at the bottom of the valve core, the section of the valve plate takes the shape of a semicircle of which the top is a straight line, the bottom of the valve plate is arc-shaped, and the radian of the bottom of the valve plate is equal to that of the inner wall of the two-way joint; the valve core is a cylinder; and the inner wall of a seal ring in contact with the valve core is conical. The discharge reduction type stop valve has the advantages that as the housing adopts the integral structure, discharge can be reduced, assembly and disassembly are easier to realize, and vulnerable elements (such as the filter element) are easier to replace. The conical valve core facilitates sealing, and owing to the design of the valve plate, damage of water pressure in the pipeline to the valve core is favorably reduced.
Description
Technical field
The utility model relates to a kind of minimizing drainage type stop valve.
Background technique
Existing minimizing drainage type stop valve, its shell mechanism often makes split-type structural, though this structure can be in casting process realized easily, for valve body, prevents that earial drainage should be for most important.Therefore the utility model provides a kind of minimizing drainage type stop valve.This stop valve structure is simple, and the design of taper valve core and valve plate can solve the above problem.
The model utility content
For solving above technical problem, the utility model provides following technological scheme: a kind of minimizing drainage type stop valve, described stop valve comprises that shell, valve rod, spring, spool, filter core and two lead to, described stem lower portion is provided with step, the step place is with spring, the bottom of valve rod connects spool, is provided with filter core between spool and the shell, and shell connects two and leads to; Described shell is integral structure; Described spool bottom has valve plate, and the cross section of valve plate is that the top is the semicircular arc of straight line, and the bottom of valve plate is arc, equates with the radian of two logical inwalls; Described spool is a cone; With the contacted seal ring inwall of spool taper shape is arranged also.
This minimizing drainage type stop valve that the utility model relates to, shell is structure as a whole, and can reduce earial drainage, and can be easier to realize dismounting, changes easily worn part filter core etc.Cone plug is conducive to sealing, and the design of valve plate simultaneously is conducive to reduce in the pipeline hydraulic pressure to the infringement of spool.
