Abstract
The utility model relates to a cylinder valve comprising a handle, a valve rod, a valve spool and a valve body with a connection nozzle of the valve body, wherein the valve body is in a hollow structure, the inside of the valve body is provided with the valve spool, the upper end of the valve body is connected with the handle, the valve rod is installed inside the valve body, a column cavity of the valve rod is arranged in the valve rod, the upper end of the valve rod is connected at the lower end of the handle, and a sealing ring is installed between the valve rod and the handle. The cylinder valve is characterized in that a spring is arranged in the column cavity of the valve rod, one end of the spring is fixed on the valve spool, and the other end of the spring is fixedly arranged on a pin at the lower end of the valve rod. The utility model has the advantages that the conditions that a repeated-filling person pries up the valve spool by using a needle point and enables the valve spool to be disengaged from the valve body and then a foreign matter is arranged between the valve spool and the valve body for underlaying so as to carry out forced repeated filling can be prevented; especially, repeated filling after the repeated-filling person disconnects and reassembles the cylinder valve can be prevented; and the structure is simple.
Description
Technical field
The utility model relates to a kind of cylinder valve.
Background technique
The non-refillable gas cylinder has makes advantages such as simple, with low cost and easy to use, and along with the development of China's economy and industrial technology, the non-refillable gas cylinder will be used in a large number in China.But many non-refillable gas cylinder users are under the ordering about of economic benefits, and reusing by nonrecoverable non-refillable gas cylinder, this is extremely dangerous.Therefore, taking technical finesse to make it can't be repeated use to the non-refillable gas cylinder is very important.
The model utility content
The purpose of this utility model provides a kind of cylinder valve, to overcome the defective that existing non-refillable gas cylinder can be repeated to use.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of cylinder valve; constitute by handle, valve rod, spool and the valve body that has a valve body connection nipple; described valve body is a hollow structure; valve inner is equipped with spool; the upper end of valve body is connected with handle; described valve rod is installed in valve inner; be provided with valve rod post chamber in the valve rod, the valve rod upper end is connected the lower end of handle, and; between valve rod and handle seal ring is housed; simultaneously, valve rod is fixed through fender bracket, and described valve rod post is provided with spring in the chamber; the lower end of spring is fixed by spool, and the upper end of compression rear spring is fixed by the pin that is located at the valve rod lower end.
The beneficial effect of cylinder valves for non-refillable cylinder described in the utility model is: the person levers up spool with needle point and makes it break away from valve body can to prevent the repeated charging, between spool and valve body, rise then with the foreign matter pad, repeated charging by force, the person that especially can prevent the repeated charging takes cylinder valve apart and re-assemblies the back repeated charging; Simple in structure.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the disassembly and assembly structure schematic representation of the described cylinder valve of the utility model embodiment.
Among the figure:
1, valve body; 2, valve rod; 3, spool; 4, spring; 5, pin; 6, fender bracket; 7, seal ring; 8, valve rod post chamber; 9, valve body connection nipple; 10, handle.
Embodiment
As shown in Figure 1; the described cylinder valves for non-refillable cylinder of the utility model embodiment; by handle 10; valve rod 2; spool 3 and valve body 1 formation that has valve body connection nipple 9; described valve body 1 is a hollow structure; valve body 1 inside is equipped with spool 3; the upper end of valve body 1 is connected with handle 10, and described valve rod 2 is installed in valve body 1 inside, is provided with valve rod post chamber 8 in the valve rod 2; valve rod 1 upper end is connected the lower end of handle 10; and 10 on valve rod 2 and handle are equipped with seal ring 7, simultaneously; valve rod 2 is fixing through fender bracket 6; be provided with spring 4 in the described valve rod post chamber 8, the lower end of spring 4 is fixing by spool 3, and the upper end of compression rear spring 4 is fixing by the pin 5 that is located at valve rod 2 lower ends.
In the use, after medium fills, remove fender bracket 6, screw handle 10, make pin 5 fractures, spring 4 elongations, spool 3 is involution valve body connection nipple 9 under spring 4 elastic force effects, and steel cylinder is closed; When opening cylinder valve, handle 10 rotates up mobile, and the effect lower compression spring 4 of spool 3 pressure medium in bottle is washed spool 3 open, makes bottle interior medium by valve body connection nipple 9 normal discharges outside the bottle; When stopping using, screw handle 10, steel cylinder is sealed again, with this open repeatedly, bolt down procedure; Medium rotates up handle 10 after discharging and finishing, and spool 3 still is enclosed in the port of valve body connection nipple 9 under spring 4 elastic force effects, thereby can't carry out repeated charging.
