Description
Technical Field
The utility model relates to a valve field especially relates to a take check valve of sensor.
Background
The check valve is a valve which is widely applied in various industries, has a simple structure, and achieves the purpose of check by mainly relying on gravity or spring action to realize the return of the valve clack. However, the existing check valves are single in function, and in some scenes in which linkage or monitoring is required to be performed through opening and closing of the check valves, the check valves are often realized by means of other equipment, so that the system is more complicated, and the cost is higher.
SUMMERY OF THE UTILITY MODEL
For overcoming the single-class not enough of current check valve function, the utility model aims to solve the technical problem that: provided is a check valve with a sensor capable of determining opening and closing of a valve flap.
The utility model provides a technical scheme that its technical problem adopted is:
take check valve of sensor, include the valve body, be located the disk seat in the valve body and be located the valve clack on the disk seat, the upper end and the disk seat of valve clack are articulated, still are equipped with the valve rod on the valve clack, and the disk seat upper end is equipped with two touch switch, and when the valve clack was in to close or opened extreme condition, the valve rod just contacted with two touch switch respectively.
Further, the upper end of the valve seat is inclined towards the inlet end of the valve body, and the valve clack is obliquely abutted against the upper surface of the valve seat.
Further, still be equipped with the maintenance hand hole board on the valve body, maintenance hand hole board passes through the screw with the valve body and is connected.
Further, the touch switch is connected with an information processing box, and the information processing box can be connected with the execution electric device of the rest production valves.
The utility model has the advantages that: through set up the valve rod on the valve clack, set up touch switch on the disk seat, utilize the valve clack to contact different touch switch at the switching in-process and come the switching state transmission of valve clack for external world or other receivers to reach control or coordinated control's purpose, simple structure is practical, can simplify system architecture, reduction in production cost.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The mark in the figure is 1-valve body, 2-valve seat, 3-valve clack, 4-valve rod, 5-touch switch, 6-maintenance hand hole plate, 7-information processing box and 8-production valve.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses a valve body 1, be located valve seat 2 of valve body 1 and be located valve clack 3 on the valve seat 2, the upper end of valve clack 3 is articulated with valve seat 2, still is equipped with valve rod 4 in valve clack 3 upper ends, and valve seat 2 upper ends are equipped with two touch switch 5, and when valve clack 3 was in and is closed or opened extreme condition, valve rod 4 just contacted with two touch switch 5 respectively.
The utility model discloses a working process is: when no fluid flows through the valve body 1, the valve clack 3 is abutted against the valve seat 2 under the action of gravity or elasticity, the valve rod 4 is contacted with one touch switch 5 above, the touch switch 5 can transmit a contact signal to the outside, and the valve body 1 is displayed in a closed state at the moment; when fluid enters the valve body 1, the valve clack 3 is flushed by the fluid, the valve clack 3 rotates upwards around a hinge point at the upper end, the valve rod 4 is separated from the upper touch switch 5 at the moment, the touch switch 5 can also transmit signals to the outside, and the valve body 1 is displayed in an opening state; when the fluid flow is large, the valve rod 4 will contact the lower touch switch 5, and the touch switch 5 transmits a signal that the valve body 1 is in a fully opened state.
In view of the simplicity of construction and the stability of the return of the flap 3, it is preferable to use a flap construction which returns by gravity, so that the valve seat 2 is arranged with its upper end inclined towards the inlet end of the valve body 1, the flap 3 likewise being inclined against the upper surface of the valve seat 2. The inclination mode is shown in figure 1, wherein the arrow direction is the fluid flowing direction, the angle ABC is between 0-90 degrees, the valve clack 3 is designed into a tendency structure, and the requirement of the valve clack opening in a micro-resistance state can be realized by changing the angle between the valve clack 3 and the fluid and combining the self weight of the valve clack 3.
In order to conveniently overhaul and adjust the valve clack 3 and the valve rod 4, an overhaul port is further formed in the valve body 1, an overhaul hand hole plate 6 is arranged at the overhaul port, the overhaul hand hole plate 6 is connected with the valve body 1 through screws, and disassembly is convenient.
Further, in the actual production process, in order to realize linkage with other valves, an information processing box 7 can be additionally arranged, the touch switch 5 is connected with the information processing box 7, and the information processing box 7 can be connected with the execution electric device of the rest production valves 8. When the information processing box 7 receives different signals transmitted by the touch switch 5, other electric devices can be commanded to act according to the setting.
The utility model discloses a set up the valve rod on the valve clack, set up touch switch on the disk seat, utilize the valve clack to contact different touch switch at the switching in-process and come the switching state transmission of valve clack for external or other receivers to reach control or coordinated control's purpose, simple structure is practical, can simplify system architecture, reduction in production cost has fine practicality and application prospect.
