Abstract

The utility model relates to the self-water return water supply valve of a double-valve type for a passenger train. The structure of the valve is an integral bivalve. A left water chamber and a right water chamber are arranged in a valve body. A set of valve cores are respectively arranged in the water chambers. Under the function of the valve cores, water can be simultaneously filled by double pipes. Water can also be delivered by a single pipe. The utility model has the advantages of strong filling capability and small ground occupation.

Description

Double-valve type self-water return water supply valve for passenger train

The utility model relates to the corollary apparatus of well on the railroad coach.

China railways passenger vehicle water supply valve kind is a lot of at present, but does not still have a kind of valve water on two railway carriages simultaneously.Along with the railway transport of passengers task increases, passenger train increases, and on adjacent sometimes two lines, has two train requirements to go up water simultaneously.Because parking period is not long, do not allow to reach one and go up another again, thereby original well of going up, a well one valve has not satisfied last water requirement.The station that for this reason has changes well dress bivalve into a well one valve, goes up outlet capacity thereby improve.But well dress bivalve must be furnished with two pipelines, two valve body mount pads, and floor area is bigger in the down-hole, and, installation bivalve little as the well space just had any problem.If the reconstruction well not only increases capital expenditure, and, influence water on the passenger vehicle more or less in construction period.

The purpose of this utility model is to release a kind of novel valve that outlet capacity is strong, floor area is little of going up.

The technical solution of the utility model is: bivalve type is made up of valve body and valve seat from backwater passenger vehicle water supply valve.Divide left and right two hydroeciums in the valve body, in adorn two cover spool and corresponding valve gaps.Spool is made up of valve rod, main valve, sluicing valve and restoring spring.Valve body left and right sides hydroecium has correspondence to send the water hole, send the water hole to link to each other with flow pipe.

Below in conjunction with embodiment the utility model is further specified:

Fig. 1. bivalve type is from backwater passenger vehicle water supply valve constructional drawing.

1 is that valve body, 2 and 3 is that valve gap, 4 is that valve rod, 5 is that main valve, 6 is that sluicing valve, 7 is that restoring spring, 8 is that total blasthole, 9 is a mount pad for sending water hole, 10.

In valve body 1, two hydroeciums about branch, in adorn two the cover spools, two valve gaps 2,3 are arranged at top.Its spool is made up of valve rod 4, main valve 5, sluicing valve 6 and restoring spring 7, coming the water hole and sending the water hole in order to control left and right sides hydroecium.In valve body lower portion one total blasthole 8 is arranged, come water pipe to join with valve body mount pad 10.At valve body left and right sides hydroecium, there are two to send water hole 9 respectively, link to each other with flow pipe.Thereby under the control of hydroecium inner spool, can make two flow pipes go up water simultaneously, also can go up water separately by a pipe, thereby improve last outlet capacity.Valve rod 4 can drive main valve 5 and sluicing valve 6 linkages from top to bottom.Main valve 5 is opened during last water, and sluicing valve 6 is closed, and after last water finishes, closes main valve 5, and sluicing valve 6 is opened, this moment can with reach 20 meters send water tube hose and the interior water of passenger vehicle Upper hose, under head of water and siphon effect, flow back in the well automatically.Therefore can avoid pipeline to freeze in the winter time, reduce the station circuit and freeze, the assurance passenger vehicle is gone up water and traffic safety on time.

Claims

1, a kind of bivalve type is made up of valve body and valve seat from backwater passenger vehicle water supply valve, it is characterized in that dividing in the valve body left and right two hydroeciums, in adorn two cover spool and corresponding valve gaps; Spool is made up of valve rod, main valve, sluicing valve and restoring spring; Valve body left and right sides hydroecium has correspondence to send the water hole, send the water hole to link to each other with flow pipe.
