Background technique
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, pressure stabilizing, shunting
Or the functions such as overflow pressure relief, existing valve wide variety, function are different.Valve makes in daily life and in people's work
With relatively broad, valve can be divided into gas valve and Liquid valve etc., suitable for different fields.Existing gas valve exists
Disadvantage is more in use process, and gas valve is easy leakage in use, and sealing performance is not strong, and gas is be easy to cause to let out
Leakage, and often there is abnormal boosting phenomenon in use in existing valve, leads to valve damage, substantially reduces valve
Service life.And the valve rod and handwheel of valve are fixedly connected, by rotation hand wheel valve rod can be moved up and down in valve body from
And valve is opened or closed, but such that part valve rod exposes in air because of rising, it is raw to will lead to part valve rod
Rust or corrosion, if constantly derusting or adding oil lubricating in moist working environment domestic demand.To solve this problem, this is practical new
Type proposes a kind of gate valve for being not easy to get rusty.
Utility model content
To overcome the problems of the prior art, the utility model proposes a kind of gate valve, including gate valve ontology, the gate valve
Ontology is mainly made of handwheel, gland, valve deck, valve rod, valve plate, valve body and sealing pair；The gate valve bodies top is solid
Surely it is connected with handwheel, handwheel is bolted mode and is fixedly connected with the top of valve rod；The gate valve body bottom portion is provided with
Valve body, body top are provided with valve deck, and valve deck with valve neck by being fixedly connected；The valve rod is arranged in valve neck；Wherein, described
Valve rod includes the first valve rod and the second valve rod, and first valve rod center is equipped with negative thread, and first valve rod is in the valve neck
Interior to be connected by bearing, the upper end of second valve rod has the pin thread to match, and second valve rod is in the valve neck
It rotates and moves up and down, second stem bottom is fixedly connected with valve plate, has through-hole on valve plate；The valve neck is internally provided with
Gland, valve rod are threadedly coupled with gland, and valve neck is internally located at gland bottom and is provided with sealing pair.
The utility model proposes the gate valve in, the gate valve ontology is made of austenitic stainless steel.
The utility model proposes the gate valve in, the mode that is bolted between the valve deck and valve neck is fixed to be connected
It connects.
The utility model proposes the gate valve in, the valve rod and the valve plate are by being threadedly engaged.
The utility model proposes the gate valve in, the through-hole on the valve plate is identical as the caliber of the gate valve ontology.
Compared with prior art, the utility model has the beneficial effects that valve rod of the invention is by the first valve rod and the second valve rod
Composition, the first valve rod and the second valve rod be arranged in valve neck, there is only opposite priming between the first valve rod and the second valve rod, two
Person is not exposed in outside air, prevents from being corroded or getting rusty in valve rod exposure air.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model gate valve.
Specific embodiment
Below in conjunction with schematic diagram to the utility model proposes be described in more detail, it is practical new which show this
The preferred embodiment of type, it should be appreciated that those skilled in the art can modify the utility model described herein, and still realize
The advantageous effects of the utility model.Therefore, following description should be understood as the widely known of those skilled in the art, and
It is not intended as limitations of the present invention.
Referring to Fig. 1, the utility model gate valve includes gate valve ontology, which is characterized in that gate valve ontology is mainly by handwheel
1, gland 2, valve deck 3, valve rod, valve plate 5, valve body 6 and sealing pair 7 are constituted；Gate valve bodies top is fixedly connected with handwheel 1,
Handwheel 1 is bolted mode and is fixedly connected with the top of valve rod；Gate valve body bottom portion is provided with valve body 6, sets at the top of valve body 6
It is equipped with valve deck 3, valve deck 3 with valve neck 8 by being fixedly connected；Valve rod is arranged in valve neck 8；Wherein, valve rod includes the first valve rod 41
With the second valve rod 42, the center of the first valve rod 41 is equipped with negative thread, and the first valve rod 41 is in passing through bearing connection, the second valve in valve neck 8
The upper end of bar 42 has the pin thread to match, and the second valve rod 42 is rotated and moved up and down in valve neck 8, the second stem bottom
It is fixedly connected with valve plate 5, has through-hole on valve plate 5；Valve neck 8 is internally provided with gland 2, and valve rod and 2 screw thread of gland connect
It connects, valve neck 8 is internally located at 2 bottom of gland and is provided with sealing pair 7.Gate valve ontology is made of austenitic stainless steel.Valve deck 3
The mode being bolted between valve neck 8 is fixedly connected.Valve rod and valve plate 5 are by being threadedly engaged.Through-hole on valve plate 5 with
The caliber of gate valve ontology is identical.
The working principle of the utility model is: handwheel 1 is rotated with ovable valve stem in gate valve body interior by hand wheel rotating,
First valve rod 41 is connect by bearing with gland 2 in gate valve body interior, when the rotation of the first valve rod 41, the second valve rod
42 screw thread by being mutually adapted with the first valve rod 41 is moved up and down in gate valve body interior, when the second valve rod 42 drives valve plate 5
When lifting, the opening in valve body 6 is opened, and when the second valve rod 42 drives valve plate 5 to move down, channel closing, sealing pair 7 ensure lock
The length of the good seal performance of valve body, valve neck 8 is determined according to operating temperature, it is ensured that the reliable leakproofness of valve stem packing, sealing
Pair 7 can effectively prevent the abnormal boosting of gasification in valve neck 8.Valve rod is sealed in valve neck 8 always when moving up and down, and prevents from being corroded
Or it gets rusty.
