Abstract
The utility model relates to a pneumatic sealed oil valve tap, belonging to the technical field of valves. The utility model is mainly used for solving the oil leakage problem caused by the following situations that the residual oil leakage phenomenon occurs when the valve tap is closed after an oil valve tap is replaced by a water valve tap, a rubber pad is easily corroded and damaged, and a valve core is hardly moved to the fully closed position when the utility model is used. The utility model is characterized in that a steel ball is used as a closing element. The utility model is sealed after a spring supports the steel ball. The valve tap is opened after a piston rod pushes downwards the steel ball. The valve tap is automatically closed by using the elasticity of the spring. The outlet diameter of an oil outlet duct is smaller than or equal to one half of the diameter of an inner duct of the oil outlet duct. The utility model has the advantages of quick valve switch, good sealing property, high durability and no residual oil leakage phenomenon.
Description
The utility model belongs to valve technology field, particularly a kind ofly is used for fuel tap or tank train head the wet goods fluid, dribbling shape closure member.
At present, all be to replace the tank train head in factory with water tap.Because water tap is to adopt rubber seal, by handling screw rod rotation its conducting of realization or closing, therefore have following deficiency: oil can corrode rubber pad, makes it rotten, and when pressure sealing, rubber pad easily damages, and produces oil leakage phenomenon; Because the effluent pipe mouth diameter is identical with the internal channel diameter, when fastening tap, the fluid that remains in the outlet pipe will drip a period of time; Regular meeting spool occurs and does not move to contract fully position, particularly night shift during use, makes that oil is a large amount of to be leaked, and not only causes waste but also make environmental pollution.
The purpose of this utility model is exactly to provide at above-mentioned deficiency a kind of and can realizes conducting rapidly or close, and can make it be in full closing state automatically when closing, no Residual oil oil droplet phenomenon, and good airproof performance, long-lived air pressure seals the fuel tap tap.
Technical solution of the present utility model is: a kind of air pressure sealing fuel tap tap, comprise cylinder valve, the oil inlet pipe, the oil outlet tube that are connected with this valve body, its special way is: in valve body with steel ball as closure member, its diameter is greater than valve body upper channel diameter, and valve interior wall is the sphere that matches with steel ball at the place, passage upper edge of oil inlet pipe.Adjusting nut has the piston rod that protrudes round platform and oil-resistant seal ring with the middle part and is encapsulated in the upper channel of valve body, and the piston rod upper end is connected with handle.The lower channel of valve body is equipped with the spring of supporting steel ball, and its end is sealed with adjusting nut.Oil outlet tube is higher than oil inlet pipe.
The diameter of the steel ball in the technical solution of the present utility model is bigger 0.5～1.2 millimeter than the upper channel diameter of valve body.
Oil outlet tube in the technical solution of the present utility model can be decurved siphunculus, and its oil outlet diameter is less than or equal to 1/2nd of internal channel diameter.
Oil outlet tube in the technical solution of the present utility model can also be that threaded straight shape pipe, elbow, oil nozzle are threaded successively and form, and the endoporus of oil nozzle is divided into different two sections of diameter, and the outlet port hole diameter should be less than or equal to 1/2nd of big bore dia.
Oil outlet tube in the technical solution of the present utility model can also be threaded straight shape pipe.
The drawing of accompanying drawing is described as follows:
Fig. 1 is embodiment 1 a structural representation;
Fig. 2 is embodiment 2,3 a structural representation.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
Embodiment 1 is a kind of tank train head as shown in Figure 1.Steel ball 7 matches with valve body 4 inwalls at the place, upper edge of oil inlet pipe 9 passages, and the bottom of steel ball 7 is with spring 5 supportings, and adjusting nut 6 can make spring 5 have enough elastic force to make steel ball be in full closing state.The diameter of steel ball 7 is bigger 0.5～1.2 millimeter than the upper channel diameter of valve body 4.The middle part of piston rod 2 has the protrusion round platform, and two oil-resistant seal rings 8 are arranged on this round platform, and adjusting nut 3 makes piston rod 2 just contact steel ball 7 and gets final product, and the upper end of piston rod 2 is connecting handle 1.The outlet port diameter of oil outlet tube 10 should be less than or equal to internal channel diameter 1/2nd.Valve body 4, oil inlet pipe 9 and oil outlet tube 10 can adopt precision casting to constitute.
Above-mentioned tank train head is connected on the fuel tank.When pressing handle 1, steel ball 7 moves down, and pressure spring 5, and the tank train head is opened, and oil flows out through oil inlet pipe 9, valve body 4 and oil outlet tube 10; Behind the loosening handle 1, spring 5 makes immediately on the steel ball 7 and moves, and the tank train head is closed, and simultaneously because the outlet port diameter of oil outlet tube 10 is less than or equal to 1/2nd of internal channel diameter, under the pressure of atmosphere, makes the Residual oil in the oil outlet tube 10 weeping not occur.
The utility model also can be used in other fluid.
The utlity model has following advantage:
The conducting that 1, can realize rapidly tank train head or fuel tap with close. Conducting when namely pressing handle, loosening handle is then closed immediately.
2, because the sphere close contact that to be the elastic force that utilizes spring match with it from steel ball and valve interior wall, thereby can automatically be in full closing state and good airproof performance when closing.
3, because the wearing and tearing of steel ball are little, so, both reliable, again durable in use.
4, because the oil-out diameter is less than or equal to 1/2nd of internal channel diameter, under the effect of atmosphere, when closing the tank train head, no Residual oil oil droplet phenomenon.
5, simple in structure, easy to use, be easy to apply.
