Abstract
The utility model provides a two-dimensional flow stop valve of an air conditioner and the stop valve is compact in structure, lower in manufacturing cost and better in circulation capability. The two-dimensional flow stop valve comprises a valve body. A refrigerant circulation channel is arranged inside the valve body and a valve stem installing hole is arranged on the valve body. A valve stem is installed inside the valve stem installing hole via a thread. Especially, the valve stem is equipped with a refrigerant circulation valve stem groove and one end of the valve stem arranged for sealing the refrigerant circulation channel is equipped with the refrigerant circulation valve stem groove. A refrigerant circulation valve body groove is arranged inside the valve body. The refrigerant circulation valve body groove is arranged at the channel port of the refrigerant circulation channel facing the valve stem. The stop valve is compact and reasonable in structure and the valve body is better in circulation capability. The valve stem is short in stroke. Meanwhile, the cost is saved and the vacuumizing efficiency of the valve body is effectively improved.
Description
Technical field
The utility model relates to the stop valve that a kind of air conditioner is used.
Background technique
There is brass to forge because air conditioner coolant specified physicochemical characteristics, the stop valve that uses on the air conditioner are all used to refrigerant, forms through machining than the strong corrosion resistant performance.
Based on present copper material resource scarcity, and the cost pressure of air conditioner producer is huge, and the method that reduces the stop valve cost of material is being sought always by part enterprise.Early stage each big producer is single cushion rubber structure by becoming two cushion rubbers, shortens the valve body height, to reduce the stop valve cost of raw material.But along with this mode the pushing open of relevant producer, competitive landscape in the industry is still severe.
As shown in Figure 1, existing stop valve is to decide stop valve to be in cut-off state or be in opening state by the position of valve rod 4 ': when valve rod 4 ' is screwed in the valve rod mounting hole 3 ' fully, valve rod 4 ' will close with its right refrigerant circulation passage 2 ', this moment, stop valve was in cut-off state; When valve rod 4 ' is screwed out in valve rod mounting hole 3 ', then refrigerant circulation passage 2 ' begins to become unimpeded, and this moment, stop valve was in opening state.The stop valve of this spline structure has only when valve rod to be screwed out stroke long enough in valve rod mounting hole 3 ', could satisfy the requirement of refrigerant fluid ability in stop valve.But the long increase that means valve body 1 ' material consumption of valve rod 4 ' stroke, this obviously is unfavorable for product competition.Need the structure of existing stop valve is further improved, to reduce its material consumption for this reason.
Summary of the invention
Provide the utility model a kind of compact structure, manufacture cost is lower, negotiability the is better two dimension air conditioner stop valve that flows.
For achieving the above object, the utility model is taked following technological scheme:
A kind of two dimension air conditioner stop valve that flows comprises valve body, is provided with the refrigerant circulation passage in valve body; On valve body, be provided with the valve rod mounting hole; In the valve rod mounting hole, valve rod is installed by screw thread; Especially, valve rod is provided with refrigerant circulation stem groove, and described refrigerant circulation stem groove is positioned at the end of valve rod in order to sealing refrigerant circulation passage; Be provided with refrigerant circulation valve body recess in the valve body, described refrigerant circulation valve body recess be positioned at valve rod the passway of right refrigerant circulation passage.
Refrigerant circulation valve body recess can allow refrigerant enter refrigerant circulation passage after opening from a plurality of directions of two dimension, increases the circulation area of refrigerant in stop valve; And the refrigerant that is provided with on valve rod circulation stem groove can reduce the resistance of valve rod to refrigerant.Therefore valve rod of the present utility model only needs to be screwed out one section short stroke, and refrigerant can pass through stop valve in a large number.Because the shortening of valve rod travel can so the material consumption of the utility model valve body can correspondingly reduce, more have superiority on cost so that the valve body length overall shortens.
Wherein, refrigerant circulation stem groove can be processed as dovetail groove, V-shaped groove, half slot, semiellipse groove etc. according to the convenience of processing and the versatility of cutter.
Above-described stop valve can have fluorinfused nozzle on the valve body, also can not have fluorinfused nozzle.With regard to the type of valve body, valve body can be general air conditioning device stop valve, square valve or special-shaped valve.
In addition, can adopt following technical measures that the utility model stop valve is done further to improve:
Seal ring between valve rod mounting hole and the valve rod is an O-ring seals, and is provided with more than one.Though increased cost of material like this, such stop valve possesses the function to the sealability double shielding, is applicable in the occasion that sealing effect is had strict demand.For realizing preventing the function that valve rod flies out, also can Non-return ring be set in the port of valve rod mounting hole or press mouth, or both and usefulness.
The utility model compact structure is reasonable, the valve body negotiability is better, and valve rod travel is short, saves cost, has improved valve body effectively and has vacuumized efficient.

Embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
As shown in Figure 2, the stop valve of present embodiment comprises valve body 1, is provided with refrigerant circulation passage 2 in valve body 1, is provided with valve rod mounting hole 3 on valve body 1, by screw thread valve rod 4 is installed in valve rod mounting hole 3.Wherein, valve rod 4 is provided with refrigerant circulation stem groove 5, and refrigerant circulation stem groove 5 is positioned at the end of valve rod 4 in order to sealing refrigerant circulation passage.Be provided with refrigerant circulation valve body recess 6 in the valve body 1, refrigerant circulation valve body recess 6 be positioned at valve rod 4 the passway of right refrigerant circulation passage.Adopt the negotiability of its valve body 1 of stop valve of this structure better, structure is compact more, more helps the operation that vacuumizes of air-conditioning producer.
In this enforcement, on valve body 1, be provided with fluorinfused nozzle 7.Also be provided with Non-return ring 8 simultaneously in the port of valve rod mounting hole 3 and be processed with pressure mouth 9, fly out to prevent valve rod 4.In the port outside of valve rod mounting hole 3, above cap nut 10 protects.According to using needs, the valve body 1 of present embodiment can only adopt a Non-return ring or a processing pressure mouthful wherein a kind of protection structure are set.
