Abstract
The utility model provides a novel key stop valve which has a simple mechanical structure, and is convenient to operate and high in fluid liquidity. The novel key stop valve consists of a valve body (1), a key switch (2), a valve rod (3), a returning spring (4), a resetting clamp tenon (5), a valve cover (6), a valve disk (7), a valve plug (8), a water inlet (9), and a water outlet (10) and is characterized in that: the key switch (2) is connected with the valve rod (3) which can move in the vertical direction; the valve rod (3) drives the valve plug (8) which is connected with the lower end of the valve rod (3) to stop fluid; the returning spring (4) is sleeved in the valve rod (3) in the vale cover; and the resetting clamp tenon (5) is arranged in the valve cover (6), and the resetting clamp tenon (5) and the returning spring (4) realize the control of the key switch over the valve plug (8). The novel key stop valve improves fluid passing capacity, reduces fluid resistance, has a simple structure, and is convenient to maintain.
Description
Technical field
The utility model relates to a kind of stop valve, relates in particular to a kind of novel push key type stop valve.
Background technique
Stop valve is meant the valve that closure member moves along the valve disc center line.According to this mobile form of flap, the variation of valve Pan port is and flap stroke relation in direct ratio.The open-shut device of stop valve is the flap of stopper, and sealing surface is the plane or the conical surface, the center line moving linearly of flap longshore current body.Because the valve rod of such valve is opened or shutoff stroke is shorter relatively, and have and cut off function very reliably, again because the variation of valve Pan port and the stroke relation in direct ratio of flap are very suitable for the adjusting to flow.Therefore, such valve is suitable as cut-out or adjusting and throttling usefulness very much.But conventional valves also exists problems in actual use, comprises that fluid resistance is big, and required power is bigger during opening and closing, is not suitable for the medium that band particle, viscosity are big, be prone to coking, and complex operation is safeguarded complicated.
Summary of the invention
In order to solve the problems of the technologies described above; The utility model provide a kind of mechanical structure simple, be convenient to operate, novel push key type stop valve that fluid flow property is good; Constitute by valve body (1), key switch (2), valve rod (3), Returnning spring (4), the trip that resets (5), valve gap (6), valve disc (7), spool (8), water inlet (9), water outlet (10); It is characterized in that said key switch connects the valve rod that can move up and down, valve rod drives the function of ending that the spool that is connected its lower end is realized convection cell, and the valve stem casing inner at valve gap is equipped with Returnning spring; Be provided with the trip that resets in valve gap inside, and realize the control of key switch spool with Returnning spring.
The beneficial effect of the utility model is: the resetting-mechanism that reset trip and Returnning spring are formed has realized being sleeved on key switch and the reset function of valve rod wherein.Key switching structure is simple, and is easy to operate, and detachable, is convenient to maintenance.The valve gap that is set with the valve rod place of Returnning spring is a Seal Design, has reduced the corrosion to spring and valve rod, has prolonged valve working life.Water outlet directly is communicated with water inlet, has improved the fluid passing ability, has reduced fluid resistance, also makes valve body structure simpler, is convenient to maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Embodiment
Key switch is fixed on valve gap (6) top through the trip that resets (5), forms resetting system with the Returnning spring (4) that is sleeved on the valve rod (3).Key switch (2) is connected with valve rod (3), and valve body (1) inside is provided with oblique tack spool (8), and valve rod (3) passes valve gap (6) and is connected with above-mentioned spool (8) with valve disc (7).Behind the switch that pushes button (2); Returnning spring (4) compression; The Fastening tenon structure that resets on trip (5) and the key switch (2) agrees with mutually, and valve rod (3) drives spool (8) and moves downward, withstand on establish with spool (8) under sealed groove; Spool (8) facade is blocked water inlet (9) and water outlet (10), realizes damming.Behind the switch that pushes button once more (2), Returnning spring (4) discharges reseting elasticity, and the Fastening tenon structure on the key switch (2) is retracted into original position, and valve rod (3) pulling spool (8) moves up, and water outlet (10) is communicated with water inlet (9), realizes through-flow.Valve gap (6) is combined closely on valve body (1) through valve disc (7), and its inside is respectively equipped with sealing configuration, has guaranteed the sealability of valve.
Claims (1)
1. novel push key type stop valve; Constitute by valve body (1), key switch (2), valve rod (3), Returnning spring (4), the trip that resets (5), valve gap (6), valve disc (7), spool (8), water inlet (9), water outlet (10); It is characterized in that said key switch (2) connects the valve rod (3) that can move up and down; Valve rod (3) drives the function of ending that the spool (8) that is connected its lower end is realized convection cell; The valve rod (3) inner at valve gap is set with Returnning spring (4), is provided with the trip that resets (5) in valve gap (6) inside, and realizes the control of key switch (2) to spool (8) with Returnning spring (4).
