Abstract
The utility model discloses a novel gate valve. The gate valve comprises a barrel-shaped valve body and a valve cap, wherein, a flash board is transversely placed in the valve body; a feed opening and a discharge opening are formed at two ends of the valve body respectively; a valve rod is rotationally arranged in the valve cap; a hand wheel is fixedly mounted at the top end of the valve rod; double-line threads are formed on the outer wall at the lower part of the valve rod; external double-line threads are formed on the flash board; and the valve rod and the flash board are in screwed connection with each other through the threads. As the valve plate is in double-line threaded fit with the valve rod, the utility model improves open-close speed, and ensures more stable operation.
Description
Technical field
The utility model belongs to valve, specifically is a kind of novel 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 throttling.Flashboard has two sealing surfaces, and two sealing surfaces of the most frequently used pattern gate valve form wedge shape.It is to regulate by the fixing handwheel of valve stem tip that flashboard moves up and down, and for single thread cooperates, keying speed is slow between the valve rod of common gate valve and the flashboard.
The model utility content
The purpose of this utility model provides a kind of novel gate valve, adopts double-start thread to cooperate between valve plate and the valve rod, the raising of keying speed, more stable work.
The technical solution of the utility model is as follows:
A kind of novel gate valve, include valve body, the valve gap of tubular, the interior horizontal flashboard that has of valve body, described two ends of valve body is respectively material feeding mouth, discharge port, be rotatablely equipped with valve rod in the described valve gap, the top of valve rod is installed with handwheel, on the outer wall of described stem lower portion double-start thread is arranged, described flashboard has interior double-start thread hole, screws by screw thread between described valve rod and the flashboard to be connected.
On the outer wall of stem lower portion of the present utility model double-start thread is arranged, described flashboard has interior double-start thread hole, screws by screw thread between described valve rod and the flashboard to be connected, and the keying speed of flashboard obviously improves, by valve rod swing arm number of turns counting, can know the folding degree size of flashboard by inference.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of novel gate valve, include valve body 1, the valve gap 2 of tubular, the valve body 1 interior horizontal flashboard 3 that has, the two ends of valve body 1 are respectively material feeding mouth 4, discharge port 5, are rotatablely equipped with valve rod 6 in the valve gap 2, the top of valve rod 6 is installed with handwheel 7, on the outer wall of valve rod 6 bottoms double-start thread is arranged, flashboard 3 has interior double-start thread hole, screws by screw thread between described valve rod 6 and the flashboard 3 to be connected.
