Abstract
The utility model relates to a leak protection valve belongs to valve technical field, mainly solves the prior art valve and leaks loss and waste and the valve problem of leaking when transmission poisonous and harmful medium that causes the pipe transmission medium. Including the valve body, its characteristics are: still include the static seal storehouse, the static seal storehouse includes the static seal cang cang body, canggai and hasp, it is internal that valve body and hand wheel all lie in static seal storehouse, wears out the static seal cang cang body and pipe connection by the guiding tube, cang gai is articulated with the static seal cangcang body on one side, and the another side passes through hasp and static seal storehouse body coupling, is provided with the sealing washer at canggai and static seal cangcang body contacting area, the hand wheel is driven perhaps by manpower drive by electrical actuator. Electrical actuator is wireless remote control or wired remote control. Stop the valve movive seal and damaged the transmission medium's that causes waste. Especially leak to the valve on the transmission pipe network of poisonous and harmful medium, it is significant.
Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of leakage resistant valve.
Background technique
Heat distribution pipeline spreads all over each corner in city, but, for a long time, heat distribution pipeline valve leaks problem can not get good solution always, the heat supply in winter phase, often can see in the street, steam explosion, this is because after valve uses a period of time, poorly sealed, the leakage phenomenon occurred, it is considerable that these reveal the energy loss caused.
In addition, the water supply network spreading all over city also exists the phenomenon of the evaporating, emitting, dripping or leaking of liquid or gas waste water resource that valve seal does not sternly cause too.
For poisonous and harmful medium transmission pipe network, more need to stop to leak.
Large bore valves is once be used on heat supply or water supply line, and great majority open and close several times leakage phenomenon will occur.Even if experience hundreds of times to open and close experiment when dispatching from the factory, but that carries out under valve both sides are without the condition of pressure reduction, often there is larger pressure reduction in valve its both sides in heat supply pipeline opening-closing process.In order to reduce operational torque, large bore valves adopts worm and gear gear mostly, the operating process opened and closed is consuming time longer, in the initial stage of valve opening process with pressure or the latter stage of closing process with pressure, the actual internal area of medium is less, pressure reduction before and after valve is comparatively large, and during the gap of medium by valve sealing face, flow velocity is very high.We are easy to notice that the initial stage of valve opening process with pressure or the medium in latter stage of closing process with pressure send ear-piercing howling by during valve gap, theory or practice all easily prove medium is very high by flow velocity during valve gap.The contaminant particles contained in medium molecule and medium washes away valve sealing face at a high speed, causes sealing surface to destroy.Due to the closedown of smaller diameter valve or the opening process used time shorter, the time that medium washes away sealing surface is shorter, and therefore the sealing surface of smaller diameter valve is not fragile.It is longer that the used time is not only closed or opened to large bore valves, open or closing process medium longer to sealing surface flushing time, and the area of large bore valves sealing surface is large, and sealing surface is destroyed a little, just easily forms larger leakage rate.
Summary of the invention
The utility model mainly solves the problem of the impaired leakage of valve seal, provides a kind of leakage resistant valve adopting static seal.
The utility model is solve the problems of the technologies described above the technological scheme taked to be:
A kind of leakage resistant valve, comprise valve body, be characterized in: also comprise static seal storehouse, described static seal storehouse comprises static seal storehouse warehouse, Cang Gai and snap close; Described valve body and handwheel thereof are all positioned at static seal storehouse warehouse, pass static seal storehouse warehouse be connected with pipeline by leading pipe;
Described Cang Gai is while hinged with static seal storehouse warehouse, and another side is connected with static seal storehouse warehouse by snap close, and Cang Gai and warehouse contact position, static seal storehouse are provided with seal ring;
Described storehouse covers and is provided with reduction valve and handgrip.
Described handwheel is undertaken driving or being driven by manpower by Vidacare corp.
Described Vidacare corp is Wireless remote control or wired remote control.
The utility model compared with prior art, has following beneficial effect:
In valve body is enclosed in by the utility model employing static seal storehouse, the rotation of handwheel is controlled by remote control unit, thus the leakage problem of valve is solved, even if the motive sealing of valve body has slight leakage, also just extremely limited, be a little leakage rate in the warehouse of static seal storehouse at most.Stop the waste that valve motive sealing damages heating power, water resources or other pipeline transmission medium caused.Particularly for the valve leak that the transport tube of poisonous and harmful medium is online, significant.
Accompanying drawing explanation
Fig. 1 is the utility model theory structure schematic diagram;
Fig. 2 be in Fig. 1 A-A to sectional view.
In figure: 1-handgrip; 2-Cang Gai; 3-reduction valve; 4-static seal storehouse warehouse; 5-seal ring; 6-handwheel; 7-valve body; 8-leading pipe; 9-snap close; 10-Vidacare corp.
Embodiment
As shown in Figures 1 and 2, a kind of leakage resistant valve, comprises valve body 7, is characterized in: also comprise static seal storehouse, and described static seal storehouse comprises static seal storehouse warehouse 4, storehouse lid 2 and snap close 9; Described valve body 7 and handwheel 6 thereof are all positioned at static seal storehouse warehouse 4, pass static seal storehouse warehouse 4 be connected with pipeline by leading pipe 8;
Described storehouse lid 2 is while hinged with static seal storehouse warehouse 4, and another side is connected with static seal storehouse warehouse 4 by snap close 9, at storehouse lid 2, warehouse 4 contact position, static seal storehouse is provided with seal ring 5;
Described storehouse lid 5 is provided with reduction valve 3 and handgrip 1.
Described handwheel 6 is undertaken driving or being driven by manpower by Vidacare corp 10.
Described Vidacare corp 10 is Wireless remote control or wired remote control.
Working principle: by the static seal between storehouse lid 2 and static seal storehouse warehouse 4, the medium that valve body 7 leaks out is limited in static seal storehouse, and the volume in this static seal storehouse is limited, therefore, when valve body 7 enters leakage after date, its leakage is limited, after leakage rate is full of static seal storehouse, no longer leaks.When needs manual adjustment valve, first reduction valve 3 can be opened, discharge certain media, to make it close to normal pressure, then open snap close 9, then raise storehouse lid 2, carry out the operation of handwheel 6.When adopting Vidacare corp actuate valve stem, can not open Cang Gai, after switching on power, drive unit obtains electric rear driving handwheel 6 and rotates, opening and closing valve.Use remote control controls the Vidacare corp 10 being positioned at static seal storehouse warehouse 4, then leak and can stop completely.
