Abstract
The utility model discloses a fluid refilling valve which comprises a body, a valve rod, a seal ring, a spring and a clamp spring, and is characterized in that an integrated valve rod for opening and closing the refilling valve is arranged in the refilling valve body. The fluid refilling valve is mainly used for the pipelines of various large refrigeration systems requiring to be refilled with fluid, the refrigerant can be refilled in the large refrigeration system with large flow and high speed through the fluid refilling valve, and the refilling valve with low flow and low efficiency in prior art can be replaced, and the fluid refilling valve can be used repeatedly and has detection effect at the same time.
Description
Technical field
The present invention relates to a kind of fluid flashing valve.
Background technique
As everyone knows, need be provided with between two containers usually in the process of irritating liquid from a container to another container and charge pipeline, at present employed charging all is provided with the charge-filling valve that is used to open and close pipeline usually in the pipeline.Charge-filling valve also claims check valve, and majority is used to be installed in the loop that need charge fluid device, mainly plays charging and detecting two effects in the loop.Existing charge-filling valve comprises body, valve rod, plays the fixedly supporting sleeve of valve rod, is installed on plug and spring on the valve rod, packing ring and O shape circle and dust cap, and structure is complicated, the manufacture cost height, it is low to charge speed.Simultaneously, the riveted joint of plug and core bar, plug is positioned at the charge-filling valve outside, charges pressure and can cause plug to break away from excessive the time, causes charge-filling valve to damage.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of simple in structure, cost is lower, can adapt to that working pressure is big, flow is big and satisfy and charge requirement, charge-filling valve that versatility is good fast.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of fluid flashing valve comprises body, valve rod, seal ring, spring, jump ring, is provided with valve rod integral type, that can make the charge-filling valve switching in the described charge-filling valve body.
Described valve rod upper end is concordant with the interface of the body of charge-filling valve, and the middle part is provided with two cutting planes that are parallel to valve rod axis, valve rod middle part outer wall and the sliding contact of charge-filling valve inner body wall, and stem bottom is provided with counterbore.
Described valve rod is with seal ring, and the intrinsic conical inboard wall of seal ring and charge-filling valve forms valve port.
Described jump ring is a prismatic, and the inwall of jump ring and body forms a valve opening.
One end of described spring is fixed with valve rod in the counterbore of stem bottom, and the other end and jump ring are connected and fixed.
Described body is provided with screw thread, body by screw thread with use unit to be connected and add a cover nut.
Compared with prior art, the invention has the beneficial effects as follows: component reduce, reduce corresponding cost; The seal ring tightness is good; It is big to bear pressure during charge-filling valve work, is suitable for multiple fluid, highly versatile.
Description of drawings
Fig. 1 is a partial sectional view of the present invention;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural representation of jump ring of the present invention.
Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
As shown in Figure 1, a kind of fluid flashing valve of the present invention comprises body 1, valve rod 2, seal ring 3, spring 4, jump ring 5, is provided with valve rod 2 integral type, that can make the charge-filling valve switching in the described charge-filling valve body 1.
As shown in Figure 1 and Figure 2, described valve rod 2 upper ends are concordant with the interface 10 of the body 1 of charge-filling valve, and valve rod 2 middle parts are provided with two cutting planes 21 that are parallel to valve rod axis, valve rod 2 middle part outer walls and the 1 inwall sliding contact of charge-filling valve body, and valve rod 2 bottoms are provided with counterbore 7.
As shown in Figure 1, described valve rod 2 is with seal ring 3, and the conical inboard wall 11 in the body 1 of seal ring 3 and charge-filling valve forms valve ports 12.
As Fig. 1, shown in Figure 3, described jump ring 5 is prismatics, and jump ring 5 forms a valve opening 6 with the inwall of body 1.
As shown in Figure 1, an end of described spring 4 is fixing with valve rod 2 in the counterbore 7 of valve rod 2 bottoms, and the other end and jump ring 5 are connected and fixed.
As shown in Figure 1, described body 1 is provided with screw thread 8 and screw thread 9, and body is connected with using unit by screw thread 8, adds a cover nut with the protection charge-filling valve by screw thread 9.
Brief description working principle of the present invention:
As shown in Figure 1, during charge-filling valve work, interface 10 is communicated with the delivery outlet of fluid tank by charging quick inserting joint, the thimble that utilization charges quick inserting joint produces thrust to charge-filling valve valve rod 2, valve rod 2 stressed pressure springs 4, when thrust is enough big, valve rod 2 inwardly slides, the valve port 12 that the conical inboard wall 11 of seal ring 3 and body 1 forms is opened, the passage that fluid forms between the cutting planes 21 of valve rod 2 and body 1, valve rod 2 enters in the charge-filling valve with the valve port 12 of conical inboard wall 11 formation of body 1, flow in the refrigeration system pipeline by valve opening 6 again, charge charging body accordingly.In charging process, when meeting the requirements of filling quantity, extract and charge quick inserting joint, valve rod 2 loses thrust, spring 4 resets, and promotes valve rod 2 and outwards slides, and seal ring 3 is at the valve port 12 between automatic seal body 1 and the valve rod 2 under the elastic force effect, play the non-return effect, thereby effectively prevent to charge the refluence of liquid.
Equally, when charge-filling valve is connected on the detecting instrument, the detection facility quick inserting joint can open valve port 12 by thimble, the detection facility internal environment with charge body device interior environmental communication, detecting instrument carries out the detection of temperature, pressure to the fluid of product inside by charge-filling valve.
