Abstract
The utility model discloses a double gate valve. The double gate valve comprises a valve body (4) and a valve rod (1) which is positioned in the valve body (4), wherein valve cores (3) are fixed on the valve rod (1). The double gate valve is characterized in that two fluid channels (2) are formed on the valve body (4); two valve cores (3) are matched with the two fluid channels (2); and the two fluid channels (2) and the valve cores (3) are opened and closed in a staggered mode. By the double gate valve, two valves and related auxiliary systems and control systems which are required by a pipeline are saved, so that the working efficiency of a user is greatly improved, and the operating cost of equipment is reduced.
Description
Technical field
The utility model relates to gate valve, especially a kind of Twin channel gate valve.
Background technique
The open-shut device of gate valve is a flashboard, and the moving direction and the flow direction of flashboard are perpendicular, and gate valve can only be made standard-sized sheet and complete shut-down; Can not do to regulate and cut stream and use; Its compact structure, the valve good rigidly, passage is smooth; Flow resistance quantity can be widely used on the pipelines such as tap water, sewage, building, oil, chemical industry, food, medicine, light textile, electric power, boats and ships, metallurgy, energy system and use as cut-off device.At present, the valve body of gate valve commonly used has only a passage, still; Often need two valves to come the fluid at same place is controlled in the production; Convenience because two valves use simultaneously, has increased by one times to auxiliary system is all corresponding with control system to the installation of the maintenance of valve; Improve user's utilization and operation cost, reduced working efficiency.
The model utility content
The purpose of the utility model solves double gate valve exactly and uses simultaneously, and operating cost is high, ineffective problem.
The technological scheme that the utility model adopts is: a kind of duplex gate valve; It comprises valve body and the valve rod that is positioned at valve body; Be fixed with spool on the valve rod; It is characterized in that described valve body is provided with two fluid passages, described spool has two and adaptive with two fluid lines, and two fluid passages and spool open and close dislocation.
Be provided with the space that supplies lower valve core to make a concession between described two fluid passages.
Two passages of described valve body are connected as a single entity through bolt.
The beneficial effect of the utility model is: because the utility model is provided with two fluid passages, can realize that dislocation opens and closes, therefore be installed in the opening and closing that can control two pipelines on the pipeline simultaneously, realize the chain control of two pipelines.Save pipeline and need use two valves and relevant auxiliary system and control system, thereby improved user's working efficiency and equipment operation cost greatly.
Description of drawings
Fig. 1 is the utility model schematic representation.
Embodiment
As shown in Figure 1, a kind of duplex gate valve, it comprises valve body 4 and the valve rod 1 that is positioned at valve body 4; Be fixed with spool 3 on the valve rod 1; Valve body 4 is provided with two fluid passages 2, and described spool 3 has two and adaptive with two fluid lines 2, and two fluid passages 2 open and close dislocation with spool 3.Be provided with the space that supplies lower valve core to make a concession between two fluid passages 2.Two passages of valve body 4 are connected as a single entity through bolt.
Claims (3)
1. duplex gate valve; It comprises valve body (4) and is positioned at the valve rod (1) of valve body (4); Be fixed with spool (3) on the valve rod (1); It is characterized in that described valve body (4) is provided with two fluid passages (2), described spool (3) has two and adaptive with two fluid lines (2), and two fluid passages (2) open and close dislocation with spool (3).
2. a kind of duplex gate valve according to claim 1 is characterized in that being provided with between described two fluid passages (2) space that supplies lower valve core to make a concession.
