Abstract
The utility model discloses a low-temperature stop valve with a discharging hole. The low-temperature stop valve comprises a valve body (1), a valve cover (2), a valve rod (3), a hand wheel (4) and a valve core, wherein the valve cover (2) is arranged on the valve body (1), the bottom of the valve body (1) is provided with the discharging hole (5) communicated with the lower cavity of the valve body (1), inner threads are arranged inside the discharging hole (5), and a plug screw (6) in threaded connection with the discharging hole (5) is arranged inside the discharging hole (5). The low-temperature stop valve has the advantages that the bottom of the valve body is provided with the discharging hole communicated with the lower cavity of the valve body, vestigital articles inside the cavity of the valve can be discharged through the discharging hole, and therefore pollution to the valve from media is reduced, service life of the valve is prolonged, and the valve can serve as the structure for decompression in some working conditions. A filler press board connected with the valve cover through an eyebolt is arranged, when the valve rod and filler relatively move to cause filler abrasion and enable a gap to be increased, the filler can be pressed tightly to be filled in the produced gap by screwing the eyebolt, and service life of the valve can be prolonged also.
Description
Technical field
The utility model relates to valve technology field, particularly a kind of cryogenic globe valve with drain boles.
Background technique
Cryogenic globe valve is mainly used in the warehousing and transportation facilities and associated pipe of the liquefied gas at low temp such as liquid oxygen, liquid argon, liquid nitrogen and LNG Liquefied natural gas, such as low-temperature pressure containers such as basin, tank car, tank containers, mainly the liquefied gas at low temp in the low-temperature pressure container pipeline mobile played the opening and closing effect.The structure of driving low temperature stop valve mainly comprises: valve body, valve gap are installed on the valve body, and handwheel is fixedly mounted on the valve rod, and valve rod is connected by screw thread and valve gap, and spool is fixed on the lower end of valve rod.When valve stopped up because of dirt, the medium of only blinding off a line was laid down the replacing valve new valve, causes certain economic loss.And the sealing of existing valvular valve rod upper end causes the filler wearing and tearing because of the relative movement of valve rod and filler, and the gap increases, and causes medium to leak outside, and causes valve to use.
The model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, a kind of drainage detained matter simple in structure, convenient is provided, prolongs the valve cryogenic globe valve with drain boles in working life.
The purpose of this utility model is achieved through the following technical solutions: a kind of cryogenic globe valve with drain boles, it comprises valve body, is installed in valve gap, valve rod, handwheel and spool on the valve body, handwheel is fixedly mounted on the valve rod, valve rod is connected by screw thread and valve gap, spool is fixed on the lower end of valve rod, the bottom of valve body is provided with the drain boles that is communicated with the cavity of resorption of valve body, is provided with internal thread in the drain boles, is equipped with in the drain boles by the connected plug screw of screw thread.
The top of described valve gap is provided with filler, the valve rod outer cover that is positioned at the valve gap top is equipped with hold-down grid, valve upper part of the cover outer wall is provided with otic placode, otic placode is provided with attachment hole, valve gap is connected with hold-down grid by the slip-knot bolt, the eyelet of the attachment hole of otic placode and slip-knot bolt is connected and fixed, and hold-down grid is pressed on the filler.
The utlity model has following advantage: the utility model is provided with the drain boles that is communicated with the cavity of resorption of valve body in the bottom of valve body, can be by detained matter in this drain boles vent valves chamber, thereby reduce medium to the pollution of valve, prolong the working life of valve, and can make the pressure release structure in some operating mode; The utility model is provided with valve gap by the bolted hold-down grid of slip-knot, when valve rod and filler relative movement cause the filler wearing and tearing, when the gap increases, filler the gap of filling up generation can be compressed by screwing the slip-knot bolt, the working life of valve can be prolonged equally.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure, 1-valve body, 2-valve gap, 3-valve rod, 4-handwheel, 5-drain boles, 6-plug screw, 7-hold-down grid, 8-otic placode, 9-slip-knot bolt.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of cryogenic globe valve with drain boles, it comprises valve body 1, is installed in valve gap 2, valve rod 3, handwheel 4 and spool on the valve body 1, handwheel 4 is fixedly mounted on the valve rod 3, valve rod 3 is connected by screw thread and valve gap 2, and spool is fixed on the lower end of valve rod 3, and the bottom of valve body 1 is provided with the drain boles 5 that is communicated with the cavity of resorption of valve body 1, be provided with internal thread in the drain boles 5, be equipped with in the drain boles 5 by the connected plug screw 6 of screw thread.
The top of described valve gap 2 is provided with filler, valve rod 3 outer cover that are positioned at valve gap 2 tops are equipped with hold-down grid 7, the outer wall on valve gap 2 tops is provided with otic placode 8, otic placode 8 is provided with attachment hole, valve gap 2 is connected with hold-down grid 7 by slip-knot bolt 9, the eyelet of the attachment hole of otic placode 8 and slip-knot bolt 9 is connected and fixed, and hold-down grid 7 is pressed on the filler.
When producing detained matter in the valve cavity of valve body 1, can detained matter be discharged by this drain boles 5, thereby reduce medium to the pollution of valve, prolong the working life of valve, and can make the pressure release structure in some operating mode; When valve rod 3 and filler relative movement cause the filler wearing and tearing, when the gap increases, the filler compression can be filled up the gap of generation by screwing slip-knot bolt 9, thereby can make valve continue to use, can prolong equally the working life of valve.
