Abstract
The utility model provides a gate valve, includes and water inlet, delivery port and valve body is provided with the hand wheel in the upper end of valve body, and the hand wheel lower extreme is provided with the valve rod, is provided with the filler in the both sides of valve rod, and the valve rod lower extreme is connected with the valve disc through the spring, is provided with water inlet, delivery port in the both sides of valve disc, be provided with first passageway, second channel and third passageway respectively in the delivery port side. The utility model discloses a gate valve can step regulating switch, reducing impact, and sealing performance is good simultaneously, and then life increases.
Description
Technical field
The utility model is related to a kind of gate valve, belongs to valve technology field.
Background technology
Gate valve is a kind of modal keying valve, is connected using flashboard or blocks the medium in pipeline.It does not allow to make
For use of damming, should avoid micro for flashboard unlatching in use, because the erosion of swiftly flowing medium can accelerate the damage of sealing surface.
Gate valve service life in the market is short, and in use for some time, sealing property is not enough.Lock on existing market simultaneously
Valve can not be classified regulation well, cause flow can not equal control, exacerbate the abrasion of gate valve.
Utility model content
For the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of gate valve, can be classified
Adjust switch, reducing impact, good seal performance simultaneously, and then service life increases.
For solving above-mentioned technical problem, the technical solution of the utility model is that a kind of gate valve, including water inlet, delivery port
And valve body, the upper end of valve body is provided with handwheel, handwheel lower end is provided with valve rod, and the both sides of valve rod are provided with filler, valve
Bar lower end is connected with valve disc by spring, and the both sides of valve disc are provided with water inlet, delivery port；It is respectively provided with delivery port side
There are first passage, second channel and third channel.
Optimize, water inlet open height is less than delivery port.
Optimize, be provided with sealing valve between valve body and valve rod.
Optimize, the lower end of valve disc is provided with sealing bed course.
The beneficial effects of the utility model are, gate valve of the present utility model, can reduce impact with step regulating switch, with
When good seal performance, and then service life increase.
Brief description
Fig. 1 is the structural representation of gate valve of the present utility model.
Specific embodiment
As shown in figure 1, a kind of gate valve, including water inlet 1, delivery port 2 and valve body 3, the upper end of valve body 3 is provided with hand
Wheel 4, handwheel 4 lower end is provided with valve rod 5, and the both sides of valve rod 5 are provided with filler 6, and spring 7 and valve disc 8 phase are passed through in valve rod 5 lower end
Connect, the both sides of valve disc 8 are provided with water inlet 1, delivery port 2；It is respectively arranged with first passage 9, second in delivery port 2 side to lead to
Road 10 and third channel 11.Water inlet 1 height is less than delivery port 2.It is provided with sealing valve 12 between valve body 3 and valve rod 5.?
The lower end of valve disc 8 is provided with sealing bed course 13.
During work, the unlatching of first passage 9, second channel 10 and third channel 11 can be controlled by controlling handwheel 4
With closing.When flow is less, only can open first passage 9, enter without making to second channel 10 and third channel 11
Become abrasion, when flow increases, first passage 9 can not meet use demand, then open second channel 10, first passage 9 and second
Passage 10 works simultaneously, increases flow.When flow continues to increase, open third channel 11, three-way pipe is opened simultaneously, and satisfaction makes
With requiring.When work completes, first passage 9, second channel 10 and third channel 11 are simultaneously closed off by handwheel 4.Simultaneously
Gate valve of the present utility model passes through to arrange filler and sealing valve, increased the overall sealing of gate valve, for the longevity improving gate valve
Order to have and act on well.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all in this practicality
Within new design concept, any modification, equivalent substitution and improvement made etc., should be included in protection of the present utility model
Within the scope of.
