Abstract
The utility model relates to a non-rising stem gate valve capable of displaying starting and stopping degree. The non-rising stem gate valve comprises a round-head valve deck (1), a hand wheel (2) and a valve rod (3), and further comprises a box body (4), a planet wheel transmission device and a starting and stopping degree indicating device, wherein the planet wheel transmission device and the starting and stopping degree indicating device are arranged inside the box body (4) and the box body (4) is connected with the round-head valve deck (1). An annular gear (5) is arranged inside the box body (4). Through the starting and stopping degree indicating device, users can know the starting and stopping degree of a valve plate inside a valve body, and applied force needed for starting and stopping the gate valve is small. In addition, the non-rising stem gate valve capable of displaying the starting and stopping degree has the advantages that the valve plate can not be stuck and is closed tightly and water leakage is avoided.
Description
Technical field

Background technique
At present, dark bar soft sealing gate valve is widely used on the pipeline of the industries such as oil, chemical industry, pharmacy, metallurgy, coal, power industry, urban water supply and sewerage, being used for the circulation of pilot line medium and blocking, is one of most widely used valve in the various fluid conveying engineerings.Be applicable to the mediums such as sewage, Yuan Shui, clear water, oil product, be not subjected to MEDIA FLOW to restriction.Dark bar soft sealing gate valve commonly used generally contains the compositions such as valve body, valve gap, valve plate, valve rod, seal ring, Stem Mut, handwheel or umbrella tooth.Rotate handwheel or umbrella tooth, rotate in valve body by valve rod, drive valve plate and rise and descend, reach the effect of opening and closing.Existing heavy caliber inside screw non-rising stem type gate valve handwheel or umbrella tooth opening force are large, open unstablely, are difficult to learn whether valve plate opens and closes puts in place, and the stuck and valve plate of valve plate easily occurs are not closed completely and cause the phenomenon of leaking.
The model utility content
Whether the purpose of this utility model solves exactly the heavy caliber inside screw non-rising stem type gate valve and opens unstable and be difficult to learn open and close and put in place.
The technical solution adopted in the utility model is: a kind of inside screw non-rising stem type gate valve that shows the keying degree, comprise round end valve gap, handwheel and valve rod, it also comprises casing and the planetary gear transmission device that is positioned at casing and the degree of keying indicating device, and casing is connected on the round end valve gap, is provided with ring gear in the casing;
Described planetary gear transmission device comprises minor axis, long planet wheel, short planet wheel and planetary wheel carrier, described handwheel is fixed in an end of minor axis, the other end of minor axis is connected with driving wheel, described planetary wheel carrier is positioned at the below of driving wheel and affixed with the valve rod end, be connected with several planet wheel shafts on the planetary wheel carrier, long planet wheel and short planet wheel are actively connected on respectively on the planet wheel shaft, long planet wheel and short planet wheel and driving wheel engagement driving, and with the ring gear engagement driving;
Described keying degree indicating device comprises pointer ring gear and fixing dial, pointer ring gear and microscler star meshed transmission gear, described fixedly dial is fixedly connected with casing, fixedly dial is marked with scale, be fixed with pointer on the pointer ring gear, pointer rotates with fixing dial with the pointer ring gear and cooperates, and indicates the switching degree.
As the novel further improvement of this use, few 2 of the number of teeth of the gear ratio pointer ring gear of the ring gear that is provided with in the described casing.
As the novel further improvement of this use, described planetary wheel carrier is connected with 3 planet wheel shafts, and 1 long planet wheel and 2 short planet wheels are actively connected on the planet wheel shaft respectively.
The beneficial effect that the utility model adopts is: after adopting this structure, inside screw non-rising stem type gate valve is opened stable, and can judge whether valve plate opens and closes by the pointer scale dish and put in place, opens and closes the needed strength that applies little, valve plate can be not stuck, and valve plate is closed tight and water-tight.

Embodiment
Shown in Fig. 1,2,3,4,5, preference of the present utility model is a kind of inside screw non-rising stem type gate valve that shows the keying degree, comprise round end valve gap 1, handwheel 2 and valve rod 3, it also comprises casing 4 and is positioned at planetary gear transmission device and the degree of the keying indicating device of casing 4, casing 4 is connected on the round end valve gap 1, is provided with ring gear 5 in the casing 4;
Described planetary gear transmission device comprises minor axis 6, long planet wheel 7, short planet wheel 8 and planetary wheel carrier 9, described handwheel 2 is fixed in an end of minor axis 6, the other end of minor axis 6 is connected with driving wheel 10, described planetary wheel carrier 9 is positioned at the below of driving wheel 10 and affixed with valve rod 3 ends, be connected with 3 planet wheel shafts 11 on the planetary wheel carrier 9,1 long planet wheel 7 and 2 short planet wheels 8 are actively connected on respectively on the planet wheel shaft, long planet wheel 7 and short planet wheel 8 and driving wheel 10 engagement driving, and with ring gear 5 engagement driving;
Described keying degree indicating device comprises pointer ring gear 12 and fixing dial 13, pointer ring gear 12 and microscler star meshed transmission gear, described fixedly dial 13 is fixedly connected with casing 4, fixedly dial 13 is marked with scale, be fixed with pointer on the pointer ring gear 12, pointer rotates with fixing dial 13 with pointer ring gear 12 and cooperates, and indicates the switching degree.
Few 2 of the number of teeth of the gear ratio pointer ring gear 12 of the ring gear 5 that is provided with in the described casing.
Rotate handwheel 2 during use and drive driving wheel 10, driving wheel 10 drives long planet wheel 7 and short planet wheel 8, long planet wheel 7 and short planet wheel 8 drive planet wheel shafts 11 drive planetary wheel carriers 9 and rotate, 3 rotations of planetary wheel carrier 9 band ovable valve stems, thus drive Stem Mut and valve plate carry out opening and closing together.Because few 2 of the number of teeth of the gear ratio pointer ring gear 12 of the ring gear that is provided with in the casing 5, pointer ring gear 12 moduluses approximately equate with the modulus of ring gear 5 gears, when so long planet wheel 7 drives ring gear 5 rotation, the drive pointer ring gear 12 of trace is done rotatablely moving of trace, and when driving wheel 10 turned around, pointer ring gear 12 rotated little by little, pointer moves little lattice, because speed ratio for this reason 3, valve rod 3 turn 1/3 circle, Stem Mut and valve plate 1/3 pitch that rises together.The valve plate stroke takes advantage of 3 to be exactly the number of turns that handwheel 2 rotates divided by pitch, calculates valve plate and reaches the position and close the number at quarter that puts in place.After having adopted this design, only need just can know that by observing keying degree indicating device the startup of the valve plate in the valve body closes degree, and this design opens and closes the needed strength that applies little so that inside screw non-rising stem type gate valve is opened stablizes, valve plate can be not stuck, and valve plate is closed sternly water-tight.
