Abstract
The invention provides a stop valve with low cost, simple structure, firm connection and good sealing performance and a connecting structure thereof. The connecting structure comprises a connecting plate, a copper connecting pipe and a fastening piece, wherein the connecting plate wraps an outer joint of a valve body; the copper connecting pipe is connected at the outer joint of the valve body; and the fastening piece presses the valve body and the connecting plate. The valve body of the stop valve is made of zinc-based alloy material so as to reduce the cost and energy consumption and save resources. The valve body and the connecting plate are connected by bolts or in a riveting manner, and a sealing ring is arranged between the valve body and the copper connecting pipe so as to carry out axial and end-surface sealing. The connecting structure of the stop valve is applicable to connection of the copper pipe and other material parts. The invention is applicable to the field of air-conditioner stop valves.
Description
Technical field
The present invention relates to fluid control field, particularly relate to stop valve and linkage structure thereof.
Background technique
Stop valve structure is widely used in the air conditioner field, and present air conditioner stop valve valve body mainly uses Cu alloy material to be made.Because copper ore resource is limited, and exists the problem that cost is high, energy consumption is big, developing other substitution material just becomes the task of top priority.On the other hand; Because the incomparable superiority of many relatively other materials of copper product; The heat exchanger pipe arrangement of most air conditioner still need adopt copper product to make, so how the part of copper pipe and other new materials carries out simply and effectively being connected to become an industry difficult problem.
Summary of the invention
The stop valve of processing by the copper substitution material that the technical problem that the present invention solves provides that a kind of cost is low, energy consumption is little, and simple in structure, be connected firmly and the linkage structure of the stop valve that is applicable to copper pipe and other materials of good airproof performance.
The technological scheme that the present invention adopts is: a kind of stop valve is provided, and its valve body is processed by Zn-base alloy.The present invention also provides a kind of linkage structure of stop valve, comprises the connecting plate that is wrapped in stop valve valve body external tapping, is connected the copper connecting tube of valve body external tapping and compresses valve body and the fastening piece of connecting plate.This linkage structure is applicable to being connected of valve body that Zn-base alloy processes and copper pipe.
Between valve body and the connecting plate for being fixedly connected.
Preferably, be connected through bolt between valve body and the connecting plate or riveted way connects.
The surface of contact of valve body and connecting tube is provided with sealing configuration.
Preferably, the axial surface of contact of valve body and connecting tube is provided with axial sealing ring, and the end face surface of contact of valve body and connecting tube is provided with end-face seal ring.
Compared with prior art, beneficial effect is:
1, the present invention adopts Zn-base alloy to replace Cu alloy material and makes valve body, can significantly reduce cost of material, and can effectively reduce the unit manufacturing energy consumption of stop valve, economizes on resources the protection environment.
2, the invention solves the industry difficult problem how copper connecting tube and the part of other materials effectively are connected, and connect fastening, good airproof performance.
Description of drawings
Fig. 1 is a plan view of the present invention
Fig. 2 is a sectional view of the present invention
Among the figure: 1: connecting tube; 2: connecting plate; 3: axial sealing ring; 4: end-face seal ring;
5: valve body; 6: fastening piece.
Embodiment
Below in conjunction with accompanying drawing the present invention is further specified; Like Fig. 1, shown in Figure 2; Be air conditioner stop valve and linkage structure thereof; Its linkage structure comprise parcel stop valve valve body 5 external tappings connecting plate 2, be connected the copper connecting tube 1 of valve body 5 external tappings and compress valve body 5 and the fastening piece 6 of connecting plate 2, fastening piece 6 adopts bolts.Wherein stop valve valve body 5 is the Zn-base alloy manufacturing, to reduce cost, to reduce energy consumption, to economize on resources.This kind Placement is applicable to being connected of valve body that Zn-base alloy processes and copper pipe.
During use, copper connecting tube 1 inserts earlier in the connecting plate 2, and it stretches into the end-face seal ring 4 that part is withstood adjacent valve body 5, and tightening fastener parts 6 carries out end face seal.Then tighten the hex head bolt of spool, utilize axial sealing ring 3 to make the axial seal of copper connecting tube 1 and spool.Firm connection and good sealing property have been realized like this.Through tightening and unscrewing hex head bolt, just can realize that the connected sum of pipeline between the air-conditioning system different piece breaks off.
