Abstract
The utility model discloses an overflow valve. The overflow valve comprises a liquid inlet, an overflow outlet and a valve body gland, wherein the tail end of the valve body gland is provided with a safety valve regulating wire in a threaded way, a safety valve top rod is provided with an inner cavity, the safety valve top rod is sleeved in the inner cavity, and a disc spring is connected between the safety valve top rod and the safety valve regulating wire; an inner cavity of the liquid inlet is provided with a steel ball, and the tail end of the safety valve top rod is pressed on the steel ball in an ejecting way. The overflow valve disclosed by the utility model has the advantages that the structure is very simple, a better sealing effect can be realized by utilizing the matching between the steel ball and the inner surfaces of a steel ball upper ring and a steel ball lower ring, the contact surfaces between the steel ball and the inner surfaces of the steel ball upper ring and the steel ball lower ring is very small, the pressure ratio between the steel ball and the steel ball upper ring as well as the steel ball lower ring is relatively large, and the sealing degree is large; a higher stable environment can be borne by both the steel ball and a metal valve seat, the expansion coefficients of the steel ball and the metal valve seat are the same, and the steel ball and the metal valve seat are suitable for being used in an environment with larger temperature difference.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of relief valve.
Background technique
Existing structure of relief valve complexity, but in the rear deleterious of long-term use, the life-span is shorter.And the factor of being expanded with heat and contract with cold affects larger.For example, the relief valve of existing conventional dependence cone and cone match, is to utilize rubber centrum and a cone match, utilizes rubber elasticity to realize press seal, but is not suitable for working under high temperature condition, and this kind of relief valve is also not suitable for the place that temperature range is larger.
Model utility content
The utility model provides for problems of the prior art and deficiency, and a kind of simple in structure but good relief valve of applicable effect is provided.
The technical scheme in the invention for solving the technical problem is: a kind of relief valve, comprise liquid entering hole and flow-off, and the valve body inner side just right with liquid entering hole is provided with valve body gland; The end thread of described valve body gland is provided with safety valve and adjusts silk, and described safety valve adjustment silk is provided with inner chamber, is set with safety valve push rod in inner chamber, and this safety valve push rod is provided with top flat, between top flat and safety valve adjustment silk, is connected with dish spring; Enclose being respectively arranged with between liquid entering hole inner chamber and valve body gland on steel ball under circle and steel ball, steel ball is positioned on steel ball and encloses under circle and steel ball, and the end of described top flat pushes up and is pressed on steel ball.Described liquid entering hole outside is set with union cap, between liquid entering hole and union cap, is set with slips.The arranged outside of this safety valve adjustment silk has pointer, has the scale coordinating with pointer in valve body gland arranged outside simultaneously.Between described safety valve adjustment silk and valve body gland, be provided with locking silk.
Effect intentionally of the present utility model: the utility model structure is very simple, utilize steel ball to coordinate and can realize good sealing effect with the internal surface enclosing under circle and steel ball on steel ball, steel ball with steel ball under circle and steel ball the internal surface surface of contact that encloses very little, both pressure is larger, seal degree is large.Steel ball and metal seat valve can bear compared with high stable environment, and both thermal expansion coefficient are identical, and the environment that the applicable temperature difference is larger is used.Spring seat is also subject to fluid pressure when bearing dish spring pressure, increase sealing effect.The utility model life-span is long, and cost is low, is applicable to promotion and implementation.
Accompanying drawing explanation
