Description
Technical field
The utility model relates to a kind of valve.
Background technique
Valve is as the switch controlling device in the airtight transmission course of flowing medium, and utilization very extensively in current society.Valve of the prior art mainly relies on the lower seal of valve acrosome lower end surface; Be in when closing at valve; Lower seal can stop the liquid leakage in the pipeline; But when valve is in open state, when promptly the valve acrosome is in uppermost position in fig-ure, can only rely on interior pad or stuffing box gland between valve gap, valve stem casing and the valve rod to play seal action.This type valve long-term open, in the closed using process, pad or stuffing box gland phenomenon such as can occur inevitably wearing out, become flexible finally causes the interior liquid leakage of pipeline in it.
The model utility content
The purpose of the utility model provides a kind of valve, overcomes the deficiency of above-mentioned aspect in the existing product.
The purpose of the utility model is to realize through following technological scheme:
A kind of valve comprises valve body and spool, and said valve body left end is provided with first Media Interface Connector; The valve body right-hand member is provided with second Media Interface Connector, is provided with the circular medium channel that connects first Media Interface Connector and second Media Interface Connector in the valve body, and the valve body top is provided with the spool mount inlet; Be fixed with spool through the spool fixed cover in the spool mount inlet, spool comprises upper valve core, valve rod and lower valve core, and upper valve core is fixed in the spool mount inlet through the spool fixed cover; The upper valve core lower end is provided with seal groove, is provided with valve rod in the upper valve core, and the valve rod upper end is connected with screw rod; The valve rod lower end is connected with lower valve core, and the lower valve core upper end is provided with the last seal ring that is complementary with said seal groove, and the lower valve core lower end is arranged in the circular medium channel; Be provided with lower seal between lower valve core lower end and the circular medium channel, the external diameter of lower seal is greater than the internal diameter of circular medium channel.
The beneficial effect of the utility model is: simple in structure; Through seal groove being set, in conjunction with the last seal ring that the lower valve core upper end is provided with, the ingenious fluid leakage problems of valve when open state that solved in the upper valve core lower end; Practical, low cost of manufacture and convenient later maintenance.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described valve of the utility model embodiment;
Fig. 2 is the structural representation of spool in the said valve of the utility model embodiment.
Among the figure:
1, valve body; 101, first Media Interface Connector; 102, second Media Interface Connector; 103, circular medium channel; 104, spool mount inlet; 2, spool; 201, upper valve core; 2011, seal groove; 202, valve rod; 203, lower valve core; 2031, go up seal ring; 2032, lower seal; 3, spool fixed cover; 4, screw rod.
Embodiment
Shown in Fig. 1-2, the described a kind of valve of the utility model embodiment comprises valve body 1 and spool 2; Said valve body 1 left end is provided with first Media Interface Connector 101, and valve body 1 right-hand member is provided with second Media Interface Connector 102, is provided with the circular medium channel 103 that connects first Media Interface Connector 101 and second Media Interface Connector 102 in the valve body 1; Valve body 1 top is provided with spool mount inlet 104; Be fixed with spool 2 through spool fixed cover 3 in the spool mount inlet 104, spool 2 comprises upper valve core 201, valve rod 202 and lower valve core 203, and upper valve core 201 is fixed in the spool mount inlet 104 through spool fixed cover 3; Upper valve core 201 lower ends are provided with seal groove 2011; Be provided with valve rod 202 in the upper valve core 201, valve rod 202 upper ends are connected with screw rod 4, and valve rod 202 lower ends are connected with lower valve core 203; Lower valve core 203 upper ends are provided with the last seal ring 2031 that is complementary with said seal groove 2011; Lower valve core 203 lower ends are arranged in the circular medium channel 103, are provided with lower seal 2032 between lower valve core 203 lower ends and the circular medium channel 103, and the external diameter of lower seal 2032 is greater than the internal diameter of circular medium channel 103.
The described valve of the utility model embodiment; Main feature is: upper valve core 201 lower ends are provided with seal groove 2011; Lower valve core 203 upper ends are provided with the last seal ring 2031 that is complementary with said seal groove 2011; Thereby when this valve is in open state, when promptly lower valve core 203 is in uppermost position in fig-ure, can because seal groove 2011 and last seal ring 2031 cooperate that still sealing is good.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technological scheme, all drops within the protection domain of the utility model.
