Description
Technical field
The utility model relates to a kind of valve body, and the utility model especially relates to a kind of fire control stop valve.
Background technique
Stop valve is the object of valve opening and the closedown realized by rotation hand wheel.Stop valve is contained in fire-fighting delivery side of pump, is mainly used in the effect cut off, regulate and prevent medium from flowing backwards.
What the outlet of existing fire-fighting truck was installed is ball valve, when fireman is when opening ball valve fire extinguishing, because the pressure of fire water pump is at 2.0 ~ 3.0Mpa, the pressure of water is too large, and ball valve is 90 ° of unlatchings, opens rapidly, the pressure moment of outlet is too large, forms very large threat to personal safety.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of safe and reliable and whole pipe-line system is played to the fire control stop valve of the effect of protection.
According to the technological scheme that the utility model provides, described fire control stop valve, comprise handwheel, upper valve rod, valve body, spacingly to pull pin, spring, lower valve rod and valve plate, valve body is provided with valve inleting water mouth and valve body water outlet, upper valve rod has been threaded connection in valve body, handwheel is fixed with in the upper end portion of upper valve rod, the hypomere of upper valve rod and the epimere of described lower valve rod are plugged in together, spring is provided with between upper valve rod and lower valve rod, valve plate is fixed with in the underpart of lower valve rod, valve body is provided with spacing pulling pin, upper valve rod offers restraining groove, restraining groove coordinates with spacing pulling pin.
The axis of described valve inleting water mouth and the axis of valve body water outlet are vertical setting.
Offer seal ring mounting groove in the lower end surface of valve plate, vulcanized rubber seal ring is installed in seal ring mounting groove.
In the hypomere of upper valve rod, offer installing blind along its axis, described spring is positioned at this installing blind, and the epimere of lower valve rod is inserted in the installing blind of upper valve rod hypomere, and upper end portion and the spring of lower valve rod offset.
The utility model has the following advantages:
1, the utility model adopts valve inleting water mouth and valve body water outlet in 90 degree of directions, can change the direction of media flow, can reduce the risk caused personal safety;
2, the utility model adopts handwheel band ovable valve stem spiral to move, and open-shut device is slowly opened, pressure is slowly raised, the pressure reduced when just opening raises suddenly, thus plays a protective role to personal safety;
3, the utility model inside adopts spring structure, when can prevent water pump from quitting work, can prevent medium from flowing backwards, avoid water hammer, play a protective role to whole system;
4, valve of the present utility model opens the spacing structure of pulling pin of rear employing completely, prevents faulty operation valve, damage threshold door, in order to avoid cause the accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
This fire control stop valve, comprise handwheel 1, upper valve rod 2, valve body 3, spacingly pull pin 4, spring 5, lower valve rod 6 and valve plate 7, valve body 3 is provided with valve inleting water mouth 9 and valve body water outlet 10, upper valve rod 2 has been threaded connection in valve body 3, handwheel 1 is fixed with in the upper end portion of upper valve rod 2, the hypomere of upper valve rod 2 and the epimere of described lower valve rod 6 are plugged in together, spring 5 is provided with between upper valve rod 2 and lower valve rod 6, valve plate 7 is fixed with in the underpart of lower valve rod 6, valve body 3 is provided with and spacingly pulls pin 4, upper valve rod 2 offers restraining groove 8, restraining groove 84 to coordinate with spacing pulling pin.
The axis of described valve inleting water mouth 9 and the axis of valve body water outlet 10 are vertical setting.
Offer seal ring mounting groove in the lower end surface of valve plate 7, vulcanized rubber seal ring 11 is installed in seal ring mounting groove.
In the hypomere of upper valve rod 2, offer installing blind along its axis, described spring 5 is positioned at this installing blind, and the epimere of lower valve rod 6 is inserted in the installing blind of upper valve rod 2 hypomere, and upper end portion and the spring 5 of lower valve rod 6 offset.
Working principle of the present utility model is as follows:
When handwheel 1 turns clockwise, upper valve shaft 2 moves down, and drives valve plate 7 to move downward, when valve plate 7 moves to the limit and valve inleting water mouth 9 make valve closing.
When handwheel 1 is rotated counterclockwise, drives upper valve rod 2 to move up, and drive valve plate 7 to move upward, when valve plate 7 moves to the limit, spacing pulling pin 4 blocks upper valve rod 2, and make it not move, in order to avoid cause damage to spring 5, now valve is all opened again.
After water pump quits work, for preventing medium from flowing backwards, spring 5 can promote valve plate 7, moves downward, and makes valve plate 7 in seal for pipe joints, prevents water hammer from producing, in order to avoid damage water pump and pipeline, thus the safety of protection whole system.
