Abstract
The utility model discloses a non-return protective cap for valve port of the valve of liquid gas tanks, which is made of rubber. The utility model is covered on the valve port of the liquid gas tank, and a protective cap is provided with a cross elastic slit which is in a closed state under the ordinary pressure. Foreign matters of sand, dust, water, etc., can not entered into the valve, and the gas leaking from the valve can be exhausted. The protective cap can prevent the breaking of the valve port.
Description
The present invention relates to adorn a kind of impurity that prevents on the valve port of liquefied gas bottle and enter the cap of valve.
Do not have cap on the valve port of liquefied gas bottle now, transporting or depositing in the process, impurity such as its sand, dust, water enter valve port easily and damage valve.
The objective of the invention is on the valve port of liquefied gas bottle, to add a non-return head protector of valve port (hereinafter to be referred as head protector), make mechanical admixture can not enter valve, and the gas of valve leak can be discharged.
Invention is achieved in that head protector made by rubber, severs a criss-cross slit on cap, and under normal pressure, the slit is closure state, if valve gas leakage is just discharged from the slit.
Below with reference to accompanying drawing invention is described in further detail.
Fig. 1 is the profile of liquefied gas bottle valve port head protector.
Fig. 2 is that head protector is contained in the situation on the valve.
Fig. 3 is the situation of air pressure when pintongs on the head protector is opened.
Head protector (1) is to be formed by the rubber compacting.Fig. 1 be head protector be enclosed within liquefied gas bottle valve port (4) on.Round edge on the cap and cross rib are thick than other position, cut a criss-cross elasticity slit (2) on rib, become pintongs, and under normal pressure, the elasticity slit is closure state.The mouth hanging (3) that a protrusion is arranged on the limit of cap has a movable hanging ring (6) on the valve (5), couple together with chain (7).
Assembling hangs over movable hanging ring on the valve body during valve, in use, head protector is contained on the valve port, and impurity such as its sand, dust, water just can not enter in the valve, if valve gas leakage, it is the elasticity slit discharge from the head protector just.Therefore head protector can play non-return effect, and it can prevent that also valve port from breaking.
Claims (1)
- The non-return head protector of a kind of valve port on the liquefied gas bottle valve, it is a rubber cap, it is characterized in that: the elasticity slit of intersection is arranged on the arc cap, be closed state under normal pressure.
