Abstract
The utility model provides a special combined filling valve for a low-temperature liquid storing and transporting apparatus. The combined filling valve comprises a valve body which is composed of a valve seat and a valve cover, valve cores which are arranged in the valve body, and valve stems which are used for controlling the valve cores. The valve body is provided with an inserting port for protecting a safety valve on line. A filling port and a residual liquid discharging port are symmetrically arranged on the valve seat along the horizontal axis thereof and a top pouring type liquid outlet and a bottom pouring type liquid outlet are symmetrically arranged on the valve seat along the vertical axis thereof. The valve cover is a macrochoanitic valve cover. The valve cores are respectively arranged on the residual liquid discharging port, the top pouring type liquid outlet and the bottom pouring type liquid outlet, and the valve stem for each valve core extends with different lengths out of the valve cover and is connected with an operating handwheel. The utility model can be used for replacing an original liquid filling system for a storage tank.
Description
The utility model relates to the valve that liquid transmission pipeline is used.What be particularly related to is a kind of system that charges that is made up of several valves that uses in the cryogenic liquide storage and transportation equipment.
The charging that system requirements possesses that the bottom charges, the top charges, residual liquid discharge, charge a function such as online protection of cryogenic liquide storage and transportation equipment.Corresponding with it, whole system charges stop valve, top and charges stop valve, charges online protection safety valve and formed with the plurality of conduits and the joint that are connected between each valve by charging interface, bottom.Its shortcoming is that pipeline is arranged comparatively complexity, and joint is many.Joint causes the possibility of pipe leakage to increase more, pipeline is arranged complexity and is caused manufacturing comparatively to bother, and because the uneven confusion that may cause tubes rows to put of manufacturer's quality and ability, influence the outward appearance and the performance index of whole cryogenic liquide storage and transportation equipment, and aesthetic appearance is poor.There is the hidden danger of operator's misoperation in the complexity that what is more important pipeline and valve are arranged.
The purpose of this utility model is intended to simplify the tubes rows that the cryogenic liquide storage and transportation equipment charges system puts, and improves systematic function, avoids misoperation and a kind of cryogenic liquide storage and transportation equipment special combination charge-filling valve is provided.
Realize the cryogenic liquide storage and transportation equipment special combination charge-filling valve of the utility model purpose; comprise the valve body that constitutes by valve seat and valve gap; the valve rod that is located at the spool in the valve body and operates the spool action; on described valve body, be provided with an online protection safety valve access port; described valve seat charges a mouth and a residual liquid discharge mouth along its horizontal axis to being provided with one; be arranged with along its vertical axis that the top charges liquid outlet and the bottom charges liquid outlet; described valve gap is the long neck shape valve gap; spool is located at the residual liquid discharge mouth respectively and the top charges liquid outlet and the bottom charges on the liquid outlet, and valve rod separately stretches out valve gap attended operation handwheel with different length.
The utility model is total to bottom set portion charge-filling valve door and top charge-filling valve door and residual liquid discharge valve mechanism in a valve body, be about to original bottom and charge that stop valve, top charge stop valve, the residual liquid discharge stop valve is combined in the cavity, connect the safety valve of relevant pressure during use at the safety on line valve interface of valve body at the cryogenic liquide storage and transportation equipment of different pressures grade, when guaranteeing to realize that cryogenic liquide charges job requirements, reduced joint, also just reduced possible leak source, overall performance is improved; The structural design of long neck shape valve gap, satisfied low temperature, deep cooling medium to its requirement.The valve rod of each spool is shape different in size to be stretched outside valve body, makes that respectively to operate handwheel height in picturesque disorder, and difference obviously makes may greatly reducing of misoperation.Head has been saved material and easy manufacturing; Reduced leak source on the other hand, misoperation may be little, and overall performance is improved greatly; Simultaneously the aesthetic appearance of whole apparatus for filling is greatly taken on a new look.
Provide embodiment below in conjunction with accompanying drawing.

The cutaway view Amplified image of Fig. 3 Fig. 2
Referring to Fig. 1～3, valve body is connected and composed by valve seat 8 and long neck shape valve gap 9,10 usefulness bolts 11, on the horizontal axis that charge mouthfuls 5,4 pairs in residual liquid discharge mouth is located at valve seat, the bottom charges liquid outlet 2 and top and charges liquid outlet 3 symmetries and be located on the vertical axis of valve seat, spool 12,13,14 correspondences separately are located at its liquid outlet, and valve rod 15,16,17 separately is shape different in size and stretches out valve body and join with separately operation handwheel 18,19,20.Each valve rod all adopts low temperature material to make, and at the surface overlaying one deck high-abrasive material that weares and teares easily.
Still can charge liquid outlet 2 in the bottom and charge liquid outlet 3 with the top and be connected one section projecting tube 6,7 respectively,, reduce the influence of welding deformation to greatest extent overall performance so that make solder joint away from sealing pair when welding is installed.
Claims (2)
1; cryogenic liquide storage and transportation equipment special combination charge-filling valve; comprise the valve body that constitutes by valve seat and valve gap; the valve rod that is located at the spool in the valve body and operates the spool action; it is characterized in that on described valve body, being provided with an online protection safety valve access port; described valve seat charges a mouth and a residual liquid discharge mouth along its horizontal axis to being provided with one; be arranged with along its vertical axis that the top charges liquid outlet and the bottom charges liquid outlet; described valve gap is the long neck shape valve gap; spool is located at the residual liquid discharge mouth respectively and the top charges liquid outlet and the bottom charges on the liquid outlet, and valve rod separately stretches out valve gap attended operation handwheel with different length.
2, cryogenic liquide storage and transportation equipment special combination charge-filling valve as claimed in claim 1 is characterized in that described bottom charges liquid outlet and top and charges liquid outlet and also be connected to one section projecting tube respectively.
