Abstract
The utility model provides a self-closing railway passenger car water feeding valve used for the water feeding of a passenger car water tank in a railway station. The utility model is composed of a water feeding joint and a pressure joint which are respectively arranged on the upper and lower ends of the valve body, as well as a movable valve core and a spring which are arranged in the channel of the valve body. The pressure joint and the well rubber pipe are in integrated connection with the water feeding valve, and then the water feeding joint is pushed to aim at the water infusion port of the passenger car water tank to realize water feeding. When the water tank is full, the water feeding joint is pulled out so that the water feeding valve is closed automatically. The water inside the rubber pipe is prevented from flowing out by the valve and the water inside the rubber pipe is made to flow back to a well, under the cooperation of a passenger car bolt. The water feeding valve saves time, reduces trouble and effectively avoids the waste of water resource, which has the advantages of compact structure, reasonable design, ingenious conception, stable and reliable work performance, convenient application, simple operation and wide industrial popularization.
Description
Technical field: the utility model relates to a kind of valve, particularly relates to the valve that uses for water on the passenger vehicle water tank in a kind of railway station.
Background technique: each railway station, the whole nation generally all is installed as the well that water is used on the passenger vehicle, the water pipe of well side is provided with valve and connects a very long sebific duct, after passenger vehicle arrives at a station, last water person just is inserted in sebific duct on the passenger vehicle water tank water filling hole, and then open well side valve door, give water on the passenger vehicle water tank.On the water tank full after, last water person must throttle down, pulls up sebific duct, perhaps pulls out sebific duct closing valve more earlier.In this process, not only go up the water employee and make trouble, and a large amount of water is dropped down on the ground, wintry weather cold especially, ponding Cheng Bing, station personnel's water ice fortune ice of also need arranging work.May influence railway transport when serious.In recent years, in order in the well side passenger vehicle bolt to be installed in the station of economizing on water, though passenger vehicle bolt close stance has the backwater function, make well side valve door with the fine backflow of the water in the sewer, correspondingly saved part water, but sebific duct in water still can trickle in the same old way, problem is not solved as yet.
Summary of the invention: the utility model mainly is solve to use existing passenger vehicle water-supply apparatus to water troublesome poeration on the passenger vehicle water tank, the problem of wasting water.
Scheme of the present utility model is as described below: this model utility comprise seal ring, sealing gasket, bolt, pressure cap, spring, clamp,, it is by up and down water swivel and compression fittings being set two ends respectively at valve body, and the realization of portable spool and spring is set in valve channel.
The beneficial effects of the utility model: this model utility is owing to taked said structure, particularly taked the spring and the portable spool that in valve channel, are provided with, add the combination of other parts, as long as compression fittings of the present utility model is connected with sebific duct, to go up water swivel aligning passenger vehicle water tank water filling hole then and upwards one push away, can go up water.Upward full back is pulled out just to next and is closed automatically.Guarantee that the water in the sebific duct does not outflow, and under the cooperation of passenger vehicle bolt, make in the sebific duct in the water backflow well.Save time, reduce trouble, effectively economize on water.In addition, also have structural design compact and reasonable, inventive concept novel uniqueness, stable and reliable working performance, manipulate simple and easy to do, advantage such as suit to widely popularize in the industry.
Description of drawings: Fig. 1 is the overall structure figure of self-closing passenger train water-feeding valve.
Embodiment: by self-closing passenger train water-feeding valve shown in Figure 1, be one by stepped shaft cover letter, a side is provided with the valve body 3 that annular boss and internal thread constitute in sleeve, valve body 3 upper ends are connected and fixed water swivel 1 through clamp 2, last water swivel 1 is a sleeve pipe, for frustum is the garden cylindricality down, intersection is an annular protrusion on the endoporus.Valve body 3 lower ends are connected and fixed compression fittings 11 through gland 10, and compression fittings 11 ports are provided with annular groove, and the top is an annular protrusion, and match with valve body 3 annular boss, are built-in with seal ring 9.Gland 10 is individual interior be frustum hole, peripheral hardware outside threads, and intermediate portion is provided with the connecting sleeve in even distribution hole.Spring 8 and removable spool 4 are set in valve body 3 passages from bottom to top.Spool 4 is that an end is uncovered cylindrical shell, and the cylindrical shell side is provided with a plurality of through holes, is connected pressure cap 6 in the bottom of cylindrical shell with sealing gasket 5 through bolt 7 and constitutes.Pressure cap 6 bottom boss can place in the upper end-hole of its lower end taper type spring 8 just.
During installation, compression fittings 11 is connected together with the utility model is whole with the well sebific duct, the interior spring 8 of valve body 3 passages this moment is releasing state, under spring 8 effects, and the through hole shutoff on the spool 4 cylindrical shell sides, this valve is a closed condition.Water in the sebific duct can not outflow.During last water, water swivel on this valve 1 is aimed at passenger vehicle water tank water filling hole upwards one push away, under thrust, spool 4 moves down, and spring 8 is compressed, and the through hole on the spool 4 cylindrical shell sides is opened and can be gone up water.Go up full back and pull out, under spring 8 elastic force effects, just close automatically to next.
