Abstract
The invention relates to an improved-sealing-ring-setting-based stop valve for an air conditioner. The stop valve comprises a valve body made of a copper material, a fluorine injection device, a valve rod, a valve element, and an upper cover nut. The valve body consists of a valve element cavity, an inlet joint, an outlet joint, a first valve element seat adjacent to the valve element cavity and the air inlet joint, a valve rod channel, a second valve element seat at the junction of the valve rod channel and the valve element cavity, and a fluorine injection nozzle. In addition, the stop valve also includes a sealing ring and a guide sleeve; the sealing ring is arranged a base plate with a counter bore; and the guide sleeve is inserted into the counter bore, and one end of the guide sleeve compresses the sealing ring and the other end is fixed with an opening end of the valve rod channel. The valve rod, the guide sleeve, and the sealing ring are in a sliding fit relation and are sealed in a liquid-gas mode. On the basis of the structure, because of improvement of the guide sleeve and the position of the sealing ring, the lengths of the valve rod channel and the valve rod can be reduced, thereby reducing the copper material consumption and lowering the cost. When the valve rod moves, no displacement of the sealing ring occurs; and the valve rod moves relative to the sealing ring, thereby improving the sealing performance.

Summary of the invention
The object of the invention is: provide a kind of stop valve improving the idle call that seal ring is arranged, it not only can shorten the length of valve stem passage and valve rod, and save material, cost is low; And good seal performance.
The present invention is achieved in that a kind of stop valve improving the idle call that seal ring is arranged, comprise valve body, note fluorine device, valve rod, spool and upper cap nut that copper product is made, described note fluorine device comprises the fluorinfused nozzle be arranged on valve body, non-return valve inside and note fluorine nut; Described valve body comprises the first valve core case and the fluorinfused nozzle of spool chamber, intake interface, interface of giving vent to anger, the first valve core case being arranged on spool chamber and intake interface adjacent, valve stem passage, valve stem passage and spool chamber intersection, spool and spool chamber screw togather, spool joins amalgamation liquid hermetic seal with the first valve core case or the second valve core case, and intake interface and valve stem passage are point-blank; The free end of valve rod has an interior hexagonal counterbore inserted for throw; Its special way is: have a counterbore in described valve stem passage, also comprises seal ring and a guide sleeve;
Described seal ring is arranged on the base plate of counterbore, and guide sleeve inserts in counterbore, and an end press seal circle, the other end and valve stem passage opening end are fixed;
Valve rod and guide sleeve and seal ring are slidably matched and liquid hermetic seal.
Described a kind of stop valve improving the idle call that seal ring is arranged, its special way is: described guide sleeve is by plastic materials.
Described a kind of stop valve improving the idle call that seal ring is arranged, its special way is: described guide sleeve is made up of metallic material.
Described a kind of stop valve improving the idle call that seal ring is arranged, its special way is: described metallic material is copper material.
Described a kind of stop valve improving the idle call that seal ring is arranged, its special way is: the opening end of described valve stem passage closes up and coordinates with guide sleeve end.
Described a kind of stop valve improving the idle call that seal ring is arranged, its special way is: described valve stem passage and counterbore adjacent have annular table, and described seal ring is arranged in annular table.
A kind of stop valve improving the idle call that seal ring is arranged of the present invention, owing to adopting such structure, the setting of guide sleeve and seal ring location improvement, can shorten the length of valve stem passage and valve rod, reduces the consumption of copper product, reduce cost; When valve rod moves, the position of seal ring is not subjected to displacement, and valve rod moves relative to seal ring, improves sealability.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of stop valve improving the idle call that seal ring is arranged, comprise the valve body 1 that copper product is made, note fluorine device, valve rod 2, spool 3 and upper cap nut 4, described valve body 1 comprises spool chamber 1B, intake interface 1C, give vent to anger interface 1D, be arranged on the first valve core case of spool chamber 1B and intake interface 1C adjacent, valve stem passage 1E, first valve core case of valve stem passage and spool chamber intersection and fluorinfused nozzle 1A, spool 3 and spool chamber 1B screw-thread fit move, spool 3 joins amalgamation liquid hermetic seal with the first valve core case or the second valve core case, intake interface 1 and valve stem passage 1E are point-blank, as shown in Figure 1, when spool 3 is adjacent with intake interface 1C, spool 3 coordinates with the first valve core case, is in cut-off state, when spool 3 and spool chamber 1B screw-thread fit move, when the second valve core case that spool 3 is adjacent with valve stem passage 1E coordinates, be in intake interface 1C and interface 1D on state of giving vent to anger.
Described note fluorine device comprises the fluorinfused nozzle 1A be arranged on valve body 1, non-return valve inside 5 and note fluorine nut 6; The free end of valve rod 2 has an interior hexagonal counterbore inserted for throw.
