Abstract
The utility model discloses an anti -leakage valve, including valve body, valve rod, O shape sealing washer, packing ring, pressure cap and be used for twisting the hand wheel that changes the valve rod, that section inner wall of pressing cap sleeve dress valve rod be bright and clean inner wall, and has laid two O shape sealing washers at this section valve rod with pressing between the cap axial interval, and the opposite side at two O shape sealing washers is established respectively to two packing rings, and forms the oil storage tank between two packing rings, have in the oil storage tank seal oily. Because the utility model discloses on the valve rod suit two O shape sealing washers to having designed the oil storage tank between two O shape circle, can having filled sealed oil in the oil storage tank, it is sealed completely to utilize sealed oil to go on the clearance, and it is sealed and lubricated to make valve O shape sealing washer when using remain the grease throughout, thereby improves the sealing performance and the durability of valve, in life -span of reinforcing valve and sealed, prevents the emergence of gas leakage accident.
Description
Technical field
The utility model relates to valve technology field, refers in particular to the valve with anti-leak function.
Background technique
The sealability of traditional cylinder valve is very poor, is generally on valve rod, be set with a seal ring.And those are filled as this class volatility of dimethyl ether and the stronger gas of permeability, owing to having high volatile volatile and permeability, be easy to leak out from seal clearance, cause the generation of gas leakage accidents.Thus, be necessary to make corresponding improvement to existing valve, to improve its sealability.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of good seal performance, long service life, can prevent the valve of Leakage Gas.
For solving the problems of the technologies described above adopted technological scheme: a kind of anti-leakage valve, include valve body, valve rod, O-ring seals, packing ring, pressure cap and the handwheel in order to twist valve rod, it is characterized in that: that section of inwall of described pressure cap suit valve rod is bright and clean inwall, and axially spaced-apart is laid with two O-ring seals between the valve rod and pressure cap of this section, two packing rings are located at the opposite side of two O-ring seals respectively, and form oil storage tank between two packing rings, there is sealing oil in oil storage tank.
Adopt the beneficial effect that the utility model brings: because the utility model has been set with two O-ring seals on valve rod, and between two O shape circles, devise oil storage tank, can filling sealing oil in oil storage tank, sealing oil is utilized to seal completely gap, make valve in use O-ring seals remained grease seal and lubrication, thus improve sealability and the serviceability of valve, strengthen life-span and the sealing of valve, prevent the generation of gas leakage accidents.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model anti-leakage valve.
Embodiment
As shown in Figure 1, a kind of anti-leakage valve, include valve body 1, valve rod 2, O-ring seals 3, packing ring 4, pressure cap 5 and the handwheel 6 in order to twist valve rod 2, in the utility model, that section of inwall that described pressure cap 5 is set with valve rod 2 is bright and clean inwall, and axially spaced-apart is laid with the opposite side that two O-ring seals 3, two packing ring 4 is located at two O-ring seals 3 respectively between the valve rod 2 and pressure cap 5 of this section, and form oil storage tank 7 between two packing rings 4, there is sealing oil in oil storage tank 7.O-ring seals 3 can be used for the sealing of sealing oil, and sealing oil can lubricate O-ring seals in order to the leakage-gap of sealed valve, thus realizes the sealing completely of valve, improves sealability and the working life of valve, prevents the generation of gas leakage accidents.
