Abstract
The utility model relates to a connection structure for a stop valve of an air conditioner, which is arranged at a connection position of the stop valve of the air conditioner and an externally connected copper pipe and comprises a connection end on the stop valve, a connection joint on the end of the copper pipe and a pressing nut. The top head of the connection joint is a sphere surface; the end surface of the connection end is an inwards concave conical surface. The connection structure has the advantages of small contact surface, good air tightness and difficult leakage. After the stop valve uses the connection structure of the utility model, the leakage frequency is reduced, the air conditioner can not pollute the environment, and the utility model conforms to the requirements of environmental protection.
Description
The utility model relates to a kind of linkage structure, particularly a kind of linkage structure of air conditioner stop valve.
In present detachable air conditioner, there are two copper pipes to be connected between indoor set and the outdoor unit.Refrigeration agent is arranged in the copper pipe, realize heat energy conversion by refrigerant cycle.Need to be provided with stop valve between copper pipe and the outdoor unit, the effect of stop valve is to extract the air in the circulation loop out and refrigeration agent injected.Therefore, be that the requirement stop valve seals, prevents freezing medium leakage in the normal using process of air conditioner.But leakage phenomenon often appears in stop valve when the use of actual air conditioner.Like this, not only can reduce air conditioner refrigeration, waste energy, and the refrigeration agent that leaks out also pollutes the environment, and do not meet environmental requirement.For this reason, many people propose various improvement to the structure of stop valve, and " the closed stop valve of split-type air conditioner " that provide as Chinese patent 92227471 is exactly an example.These improvement generally are to carry out at the structure of stop valve.And the inventor finds by a large amount of factual surveies, and the position that the most normal appearance is leaked is the joint of stop valve and copper pipe.This is because the sealing contact surface at present this place is the plane, what area of contact was big, poor air-tightness caused.
The purpose of this utility model is to overcome the problems referred to above, proposes a kind of linkage structure of air conditioner stop valve of novelty, solves the leakage phenomenon of stop valve.
The linkage structure of this air conditioner stop valve is in the joint of air conditioner stop valve and external copper pipe, it comprises the connecting end on the stop valve, the connecting head and the gland nut of copper pipe end, it is characterized in that: the top of connecting head is the ball face, and the end face of connecting end is inside recessed conical surface.
In the above-mentioned structure, contact with connecting end on the stop valve, form linear contact by the spherical surface of connecting head.Like this, the surface of contact of linkage structure is little, tightness good, not easy-to-leak liquid.Show through actual detected: after stop valve adopted linkage structure of the present utility model, its leakage value descended greatly, air conditioner was not polluted the environment, compliance with environmental protection requirements.
The utility model is described in further detail below by embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of air conditioner stop valve in the utility model.
Fig. 2 is a generalized section of the present utility model.
Among the figure, 1, valve body; 2, connecting end; 3, connecting head; 4, copper pipe; 5, gland nut; 6, transition tube; 7, air vent.
As shown in Figure 1, the air conditioner stop valve of the utility model indication is installed in the joint of outdoor unit with the copper pipe that is connected indoor set of detachable air conditioner, and the pipe on its valve body 1 top feeds in the outdoor unit.Also has air vent 7 on the valve body 1.Before refrigeration agent injected, the air in the pipeline will be extracted out from air vent 7.Then, inject refrigeration agent.In case air conditioner comes into operation, air vent 7 is in sealing state.
As shown in Figure 1, in structure of the present utility model, connecting end 2 end faces of valve body 1 sidepiece are inside recessed conical surface.As can be seen from Figure 2, the size of the spherical top of connecting head 3 matches with it.The spherical top of connecting head 3 is bigger, forms a convex edge, and gland nut 5 is buckled on this convex edge, and connects with the connecting end 2 of valve body 1 by screw thread.Therefore, by tightening gland nut 5, the ball type of contact surface roof pressure that can make connecting head 3 forms linear contact on the conical surface of connecting end 2.In the present embodiment, between connecting head 3 and the copper pipe 4 transition tube 6 is set also, links to each other by welding between transition tube 6 and connecting head 3 and the copper pipe 4.Such structure makes not only good airproof performance of air conditioner stop valve, and the technology of manufacturing is simple, has stronger practicability.
