Abstract
The utility model relates to a mechanical accessory, in particular to a valve used for controlling the on/off of gas. The valve mainly comprises a valve body, wherein a gas source hole and a gas delivery hole are arranged in the valve body; a valve rod is connected with the valve; an electricity discharging rod is arranged on the valve; and a sealing gasket is sleeved on the electricity discharging rod. As the valve adopts the technical scheme, the area of sealing materials impacted directly by oxygen is reduced, and static electricity produced by gas friction can be discharged quickly; therefore, the burning of the sealing materials is prevented, and the occurrence of safety accidents is reduced and even avoided.
Description
Technical field
The utility model relates to a kind of mechanical fitting, especially relates to a kind of valve that is used for the control gaseous break-make.
Background technique
The sealing mechanism of tradition gas valve all adopts the monoblock sealing material to fill in the valve cast, be combined to form seal assembly by sealing material and valve cast, sealing plane and valve body latus rectum sealed mouth by seal assembly are close to mutually, thereby guarantee the sealability of valve, if but the sealing mechanism of this cylinder valve is applied on the oxygen bottle, because oxygen is combustion-supporting gas, often in moment of valve opening, the gas flow at high speed, produce static at the sealing surface place, cause oxygen to add helping the burning of sealing material, cause security incident, cause casualties and property loss.Though, traditional cylinder valve manufacturing enterprise also develops the advanced material of some processing technologys on the sealing material of oxygen valve, for example in gasket material, add the electric conductivity that one-tenth such as carbon fiber, copper powder assign to increase sealing gasket, phenomenon such as the relative like this leakage that has reduced valve and burning.But because these materials are very different and the unstability of manufacturing process, actual behaviour in service is also not really desirable, has similar leakage and pyrophoricity accident still to happen occasionally.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of elimination when the gas flow at high speed and the valve of the static that produces.The technological scheme that its technical problem of solving the utility model adopts is: a kind of valve, and it mainly comprises and is provided with air source hole, transfer port in the valve body, and valve rod connects valve, and valve is provided with releases torch, releases and is with sealing gasket on the torch.Technical problem to be solved in the utility model also can further be solved by following technical solution: have relief hole on the valve.The utility model is owing to adopt technique scheme, reduced the area that oxygen directly impacts sealing material, and the electrostatic energy that gas friction is produced discharges rapidly, has prevented the burning of sealing material, reduces and even stopped the generation of security incident.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment of the utility model the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the F portion enlarged view of Fig. 1.
Fig. 3 is the A-A partial sectional view of Fig. 2.
Embodiment
Embodiment 1: with reference to Fig. 1, Fig. 2, Fig. 3.Be provided with air source hole 2, transfer port 3 in the valve body 1 of the present utility model, handwheel 9 connects valve 5 through valve rod 4, and valve 5 is provided with sealing gasket 6, releases torch 7 and relief hole 8.
Gas circuit of the present utility model is in closed condition among Fig. 1.Rotate handwheel and force valve rod to rise, make gas circuit of the present utility model be in opening state along the shaft axis spiral of valve body.In the moment that the utility model gas circuit is opened or closed, produce static as the sealing surface place, can be by releasing the torch release electrostatic, to realize goal of the invention of the present utility model.
Embodiment 2: with reference to Fig. 1, Fig. 2, Fig. 3.Present embodiment has been offered a relief hole on valve, to eliminate the air cavity that exists between sealing gasket and the valve, be convenient to sealing gasket and insert valve.
Claims (2)
