Abstract
The utility model is an improvement of the traditional stored type pressure container valve gate. Based on the traditional metallic valve gate, the utility model is connected with a non-metallic one-way check valve gate. The non-metallic one-way check valve and the metallic valve gate form an interlock. The one-way check valve gate consists of a metallic ram, a non-metallic valve gate and a non-metallic valve body. The non-metallic valve gate is connected with the metallic valve gate through the metallic ram. The utility model has the advantages of reasonable structure, excellent sealing property and has the function of pressure proof, sealing and anti-corrosion. The utility model opens new channel for the traditional valve gate.
Description
Technical field
The utility model relates to a kind of pressure-storing type container valve, and the synchronous composite valve that particularly a kind of pressure-storing type pressurized container that is suitable for the splendid attire chemical solution uses is the improvement to traditional pressure-storing type valves of pressure vessel.
Background technique
Be used to load the pressure-storing type pressurized container of chemical solution, all need mounted valve.Because the pressurized container internal pressure is bigger, for safety, this class valve is generally all made with metal.Metal valve sound construction but not corrosion-resistant, after the long-term contacting metal of some chemical solutions is often arranged, chemical solution meeting and metal ion reaction, the chemical property of destruction solution, particularly when the chemical solution of splendid attire was not suitable for long-term and Metal Contact, this contradiction was just more apparent outstanding.For example, in storage, in transit, container is easy to fall down very, and at this moment chemical solution just can pass through valve passage, touches the inwall of metal valve, causes the chemical action of chemical solution and metal ion.
Summary of the invention
The utility model is designed the synchronous composite valve of a kind of pressure-storing type pressurized container, on the basis of virgin metal valve, connects a nonmetal one way stop peturn valve, to reach withstand voltage, the etch-proof again purpose of sealing.
The utility model is made up of metal valve stem 1, metal valve body 2, airtight " O " type circle 3, fixing ring 5, metal valve 6 and Returnning spring 7 etc., be connected with nonmetal one way stop peturn valve in the end of metal valve 6, one way stop peturn valve and valve 6, valve rod 1 constitute linkage.One way stop peturn valve is made of metal connecting rod 8, nonmetal valve 9 and nonmetal valve body 10, and connecting rod 8 one ends are fixed in the valve 9, and the other end is by being threaded in the metal valve 6, and nonmetal valve body 10 is threaded with metal valve body 2 usefulness.
The utility model product is on the basis of former valve, connects a nonmetal one way stop peturn valve.It and original metal valve are synchronized with the movement, and promptly when metal valve was in opening state, one way stop peturn valve also was in the enable possition; Otherwise two valves are in closed condition simultaneously.In the above-mentioned motion of valve, metal valve plays a part airtight and sealing/unlatching, and one way stop peturn valve then when closing, plays a part to intercept chemical solution, so can be referred to as " composite valve synchronously ".
Accompanying drawing 1 is structural representation of the present utility model (sectional view).
Accompanying drawing 2 is structure connection diagrams of the present utility model.
Among Fig. 1,1. metal valve stem, 2. metal valve body, 3. airtight " O " type circle, 4. penetrate passage, 5. fixing ring, 6. metal valve, 7. Returnning spring, 8. metal connecting rod, 9. nonmetal valve, 10. nonmetal valve body, 11. suction passages.
Among Fig. 2,1. metal valve stem, 2. metal valve body, 6. metal valve, 8. metal connecting rod, 9. nonmetal valve, 10. nonmetal valve body, 11. suction passages, 12. airtight " O " type circle, 13. container bottle valve bases, 14. container bottle.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Among Fig. 1, metal valve body 1, airtight " O " type circle 3, fixing ring 5, metal valve 6, Returnning spring 7 are assemblied in the metal valve body 2.These 6 parts constitute original pressure-storing type pressurized container metal valve.Metal connecting rod 8, nonmetal valve 9, nonmetal valve body 10, these 3 parts constitute nonmetal one way stop peturn valve.Both connections, a part are by screwed metal connecting rod 8, screw in the lower end of metal valve 6.Another part is to be threaded with metal valve body 2 usefulness by nonmetal valve body 10.
Among Fig. 2, composite valve is installed on the container bottle 14 by container bottle valve base 13, and airtight " O " type circle 12 can prevent the liquid leakage in the container bottle.
The utility model working principle is as follows: when valve assembly was in closed condition, under a top of Returnning spring 7 and container internal pressure, metal valve 6 and nonmetal valve 9 were all in the closed position.Fixing ring 5 on the metal valve 6 plays main sealing process, guarantees that the pressure of internal tank can not leak.But not metal valve 9 plays iris action, when preventing that vessel side from falling, and chemical solution flow valve assembly inside.When applying a downward pressure on the top of metal valve stem 1, coupled metal valve 6 will move down.Because metal valve 6 can link to each other with nonmetal valve 9 by metal connecting rod 8.So nonmetal valve 9 moves down too.With under the moved further, passage is opened.Because airtight " O " type circle 3 is airtight parts, therefore under the pressure-driven of internal tank, chemical solution can only suck from suction passage 11, through behind the passage of valve assembly, ejects by penetrating passage 4.
The utility model is the improvement to conventional valves, its good airproof performance, and jet power is strong, has withstand voltage, sealing, etch-proof effect, for the purposes of expansion valve provides a kind of practical means.
