Abstract
A straight through type scavenging valve relates to the scavenging valve technical field, wherein the upper end of the valve body is provided with a valve cap provided with an upper air inlet and an upper air outlet, a valve pin is provided in the valve body, whose upper end is provided with a seal gasket, a lower air inlet and a lower air outlet are provided under the valve body, the valve pin is provided with a valve pin air inlet and a valve pin air outlet, a compression spring is provided under the valve pin, a counterweight float is connected with the lower side of the valve pin and is balanced with the elastic force of the compression spring. The straight through type scavenging valve has small volume, simple structure and low cost, can quickly supply much air, and has fast response, high sensitivity and high working efficiency in containers or pipeline systems, the application for the instable area with the impact of much fluid, durability, long service and high reliability. The straight through type scavenging valve is suitable for the containers or pipeline systems transmitting various liquids, especially suitable for the instable areas with high air charge and discharge capacity or with the impact of much fluid.
Description
Technical field
The present invention relates to scavenging air valve, is a kind of straight-through type scavenging air valve specifically.
Background technique
We know, existing straight-through type scavenging air valve, a kind of is to be provided with valve core case above valve body, and the valve core case top is provided with relief opening, and the valve core case center is provided with spool, spool is provided with sealing gasket, the spool below is provided with guide rod, and the valve core case below is provided with lever dolly, hinge connection float lever on the lever dolly, float lever is provided with float, and float lever connects mutually with lower end of the guide rod; Another kind is to be provided with valve core case above valve body, the valve core case top is provided with relief opening, the valve core case center is provided with spool, spool is provided with sealing gasket, the spool below is provided with guide rod, the valve core case below is provided with lever dolly, hinge connection connecting rod on the lever dolly, connecting rod below hinge connection float lever, float lever is provided with float, connecting rod connects mutually with lower end of the guide rod, liquid level rises and drives the float rising, drives float lever or connecting rod and rises, and drives guide rod and rises, drive spool and open relief opening, the gas in amount discharge container or the pipe-line system.This straight-through type scavenging air valve, because the spool below is provided with guide rod, the valve core case below is provided with lever dolly, hinge connection float lever on the lever dolly, float lever is provided with float, and float lever connects mutually with lower end of the guide rod or the spool below is provided with guide rod, and the valve core case below is provided with lever dolly, hinge connection connecting rod on the lever dolly, connecting rod below hinge connection float lever, float lever is provided with float, and connecting rod connects mutually with lower end of the guide rod, volume is big, complex structure, cost height, poor reliability, life-span is short, when need replenishing a large amount of air, because of the relief opening at spool place is too little, the gas flow wretched insufficiency, slow in reacting, sensitivity is low, and container or pipe-line system inefficiency are particularly in the unexpected unstable occasion that big flow hydraulic shock occurs, damage spool sealing, poor reliability easily.
Summary of the invention
The technical problem that the present invention solves is that it is big to solve volume, complex structure, the cost height, poor reliability, the life-span is short, when need replenishing a large amount of air, because of the relief opening at spool place is too little, the gas flow wretched insufficiency, slow in reacting, sensitivity is low, container or pipe-line system inefficiency particularly in the unexpected unstable occasion that big flow hydraulic shock occurs, damage the spool sealing easily, the problem of poor reliability, provide a kind of volume little, simple in structure, cost is low, can replenish a large amount of air fast, reaction velocity is fast, and is highly sensitive, container or pipe-line system high working efficiency, particularly in the unexpected unstable occasion that big flow hydraulic shock occurs, not fragile, the life-span is long, the straight-through type scavenging air valve of good reliability.
Technological scheme of the present invention is, the valve body upper end is provided with bonnet, bonnet is provided with porting, is provided with spool in the valve body, and its main structure characteristics are, the spool upper end is provided with sealing gasket, the valve body below is provided with down porting, and spool is provided with the spool porting, and the spool below is provided with pressure spring, the spool below connects the counterweight float, the Spring balanced configuration of counterweight float and pressure spring.
The invention has the beneficial effects as follows, because the spool upper end is provided with sealing gasket, the valve body below is provided with down porting, spool is provided with the spool porting, and the spool below is provided with pressure spring, and the spool below connects the counterweight float, the Spring balanced configuration of counterweight float and pressure spring, volume is little, and is simple in structure, and cost is low, can replenish a large amount of air fast, reaction velocity is fast, and is highly sensitive, container or pipe-line system high working efficiency, particularly in the unexpected unstable occasion that big flow hydraulic shock occurs, not fragile, the life-span is long, good reliability.The present invention is applicable to the container or the pipe-line system of carrying various liquid, is specially adapted to the unstable occasion that big flow hydraulic shock appears greatly or suddenly in the intake and exhaust amount.

Fig. 2 is another structural representation of the present invention.
Embodiment
Straight-through type scavenging air valve as shown in Figure 1, valve body 6 upper ends are provided with bonnet 1, and bonnet 1 is provided with porting 10, is provided with spool 3 in the valve body 6, and spool 3 upper ends are provided with sealing gasket 2, and sealing gasket 2 can seal porting 10.Valve body 6 belows are provided with down porting 8, and spool 6 is provided with spool porting 9, and following porting 8, spool porting 9, last porting 10 can advance the gas in amount discharge container or the pipe-line system.Spool 3 belows are provided with pressure spring 5, and pressure spring 5 can promote spool 3, drive sealing gasket 2 sealings and go up porting 10.Spool 3 belows connect counterweight float 7, and counterweight float 7 disposes with the Spring balanced of pressure spring 5.Counterweight float 7 can be as shown in Figure 1 through valve rod 4 rigid spool 3 belows that are connected, and counterweight float 7 also can be as shown in Figure 2 through chain 4 soft spool 3 belows that are connected.Liquid level descends, and under the effect of spool 3 negative pressure in the gravity of counterweight float 7 and system, the elastic force that overcomes pressure spring 5 moves down rapidly, and gas is from last porting 10, spool porting 9, porting 8 is discharged or entered the system down; Liquid level rises and contacts counterweight float 7, spool 3 is closed rapidly under the promotion of buoyancy and pressure spring 5 elastic force, reaction velocity is fast, highly sensitive, container or pipe-line system high working efficiency, particularly, not fragile in the unexpected unstable occasion that big flow hydraulic shock occurs, life-span is long, good reliability.
