Abstract
The utility model is a gate valve for liquids, comprising a three-way tube valve in which a ball spool is arranged with a rotary rod on the top reaching out of the tube from the top of the valve body. The ball spool and the rotary rod are designed into one piece which can not be parted. The diameter of the tube on the top of the valve body is bigger than the diameter of the ball spool. The ball spool and the rotary rod are inserted into the valve body through the tube on the top of the valve body when they are arranged. The utility model has the advantages of safety, reliability, and long life cycle.
Description
Technical field
The utility model relates to a kind of fluid gate valve.
Background technique
Popular in the market fluid gate valve has multiple, but the spool 7 of all gate valves is not a disjunctor with the bull stick 6 of controlling its rotation as shown in Figure 1, but finishes by cooperations such as chase mortises.This connection is not very reliable, and spool is uncontrolled easily, especially after occurring using wearing and tearing.In addition, most gate valve just occurs leaking after its spool uses wearing and tearing, gas leak phenomenon, just can not re-use.
Summary of the invention
The purpose of this utility model is to exist the easy uncontrolled problem of spool at present gate valve, and a kind of fluid gate valve safe and reliable and simple in structure is provided.
The purpose of this utility model is achieved in that the utility model comprises the threeway tubular valve body, in valve body, be provided with spherical valve core, the top of spherical valve core is provided with a bull stick, stretch out from the mouth of pipe of valve body top bump at the top of bull stick, described spherical valve core and bull stick are inseparable one design, and the nozzle diameter of valve body top bump is greater than the diameter of spherical valve core.In spherical valve core and bull stick are packed the chamber of valve body into from the mouth of pipe of valve body top bump when mounted.
Technique effect of the present utility model is: because spherical valve core and bull stick are inseparable one design, their phenomenons in the joint wearing and tearing appear never, the phenomenon that spherical valve core is not subjected to bull stick control can not appear yet, so the utility model is safe and reliable, and long service life.
The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment
To shown in Figure 6, embodiment one comprises valve body, incorporate spherical valve core 2 and bull stick 5, valve gap 4 as Fig. 1; Valve body is the threeway tubulose, it is made up of the main body 1 and the connecting tube 3 of threeway tubulose, main body 1 is at its top, left end and right-hand member are respectively equipped with the mouth of pipe 101,103,102, in these three mouths of pipe, be equipped with internal thread, the diameter of the mouth of pipe 101 of main body 1 top bump is greater than the diameter of spherical valve core 2, in inseparable incorporate spherical valve core 2 and bull stick 5 are packed the chamber of main body 1 into from the top mouth of pipe 101 of main body 1, stretch out from the mouth of pipe 101 at main body 1 top at the top of bull stick 5, the inner of connecting tube 3 is provided with outside thread, with the mouth of pipe 103 of main body 1 left end by being threaded togather, connecting tube 3 with withstand spherical valve core 2 after main body 1 is connected, the inner of the inner chamber of main body 1 and connecting tube 3 is processed into circle and is matched with spherical valve core 2, spherical valve core 2 rotates in round chamber, and the mouth of pipe is provided with internal thread in the outer end of connecting tube 3; The mouth of pipe 101 places at main body 1 top also are connected with a tubulose valve gap 4, and valve gap 4 lower ends are provided with outside thread and are connected with internal thread on the main body 1 top mouth of pipe 101, and stretch out from valve gap 4 at the top of bull stick 5.
As shown in Figure 7, embodiment two is with embodiment's one difference: the shape of both valve body main bodys is different, embodiment two main body 8 leading shapes.The utility model is adapted to the valve body of different shape.
As shown in Figure 8, embodiment three is with embodiment's one difference: embodiment three is provided with an eyelet 10 at the joint of main body 9 and connecting tube 11, on eyelet 10, be provided with one with external force can make eyelet 10 this place disconnection fracture zone.The effect that the utility model is provided with eyelet is: make it cooperate tight with spherical inner chamber and cause leaking gas or when leaking when wearing and tearing appear in spherical valve core, eyelet is removed, again connecting tube is screwed toward in and make it withstand spherical valve core again, thus the problem that can solve gas leakage or leak.
