Abstract
The utility model discloses a kind of improved fuel outlet valves, including the valve body for setting runner and the nonreturn valve core being located on valve body inner flow passage, the valve body includes setting externally threaded valve rod and the bonnet for being located at the valve rod rear end, the first opening and the second opening being connected to the runner are respectively equipped on the side wall of the valve rod and the axis of bonnet, first opening is kidney slot.The utility model is due to the kidney slot that the first opening being connected to runner being equipped on valve rod is strip, no matter whether the thickness of gear case oil bottom case changes, it does not influence machine oil to be discharged and inject through runner from the first opening so that the utility model can adapt to the various gear case oil bottom cases of different-thickness.
Description
Technical field
The utility model belongs to fuel outlet valve, and in particular to a kind of improved fuel outlet valve.
Background technology
Widely used gear-box speed change in vehicle, ship, engineering equipment replaces the weight that machine oil is gear-box repair and maintenance
Want content.In order to replace machine oil, gear-box uses the structure that oil-draining screw is arranged in oil sump.But traditional gear-box is drained the oil spiral shell
It is inconvenient when pin structure operates, it directly drains the oil and is easy to influence environmental sanitation.
In the prior art, also have and original oil-draining screw is replaced using a kind of fuel outlet valve in gear case oil bottom case, pass through stream
Body is quickly let out dress rifle and is used cooperatively with it, and quick drain waste oil, cleaning are realized in the opening and closing that fuel outlet valve is controlled by letting out dress rifle
Machine oil is replaced with filling.But this fuel outlet valve still has some shortcomings in design, in order to adapt to the gear of different-thickness
Case, it is necessary to which the fuel outlet valve for using different length causes its specification more, and production cost is high.
Utility model content
The purpose of this utility model is in view of the problems of the existing technology, to provide a kind of good improved of adaptability and put
Fuel tap.
What the technical solution of the utility model was realized in：
Improved fuel outlet valve provided by the utility model, including set the valve body of runner and be located at unidirectional on valve body inner flow passage
Spool, the valve body include setting externally threaded valve rod and the bonnet for being located at the valve rod rear end, the side wall and bonnet of the valve rod
Axis on be respectively equipped with the first opening and the second opening being connected to the runner, first opening is kidney slot.
The runner is equipped with conical valve seat, and the front end in the valve rod is equipped with axle sleeve, and the nonreturn valve core includes being located at
Valve rod in the axle sleeve, the cone valve core print coordinated with the conical valve seat for being located at the valve rod rear end, be set in it is described
Spring on valve rod and between the valve core head and axle sleeve.
The valve core head is equipped with conical seal ring and coordinates with the conical valve seat.
The beneficial effects of the utility model：
The utility model due to the kidney slot that the first opening of being connected to runner of being equipped on valve rod is strip, no matter
Whether the thickness of gear case oil bottom case changes, and does not influence machine oil and is discharged and injects through runner from the first opening so that this reality
With the novel various gear case oil bottom cases that can adapt to different-thickness.
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structure and scheme of installation of the utility model.
Specific implementation mode
See Fig. 1, improved fuel outlet valve provided by the utility model, including sets the valve body of runner 12 and be located at valve body inner flow passage
On nonreturn valve core, the valve body includes the valve rod 1 for setting external screw thread 6 and the bonnet 7 for being located at 1 rear end of the valve rod, the valve rod 1
Side wall and bonnet axis on be respectively equipped be connected to the runner 12 first opening 3 and second opening 8, described first opens
Mouth 3 is kidney slot；The runner 12 is equipped with conical valve seat 9, and axle sleeve 2, the check valve are fixedly arranged at the front end in the valve rod 1
Core includes the valve rod 4 being located in the axle sleeve 2, is located at the taper valve core of 4 rear end of the valve rod coordinated with the conical valve seat 9
First 11, it is set in the spring 5 on the valve rod 1 and between the valve core head 11 and axle sleeve 2；The valve core head 11 is equipped with
Conical seal ring 10 coordinates with the conical valve seat 9.
When the utility model is used, fuel outlet valve is fixed on by gear case oil bottom case A by the external screw thread 6 on valve rod 1
On, and washer 13 is set between bonnet 7 and gear case oil bottom case A.When with letting out dress rifle（It does not draw）After being installed on bonnet 7, let out
The thimble filled on rifle is open-top by nonreturn valve core, so that the cone valve core print 11 in nonreturn valve core is detached from conical valve seat 9, opens runner
12, the used oil in gear-box is flowed into from the first opening 3 on valve rod 1 through the opening of runner 12 and second 8 along arrow to be let out dress rifle and returns
It receives, cleaning oil and new machine oil enter in gear-box through runner 12 from letting out dress rifle again, are automatically performed waste oil discharge, babinet cleaning and new
The operations such as oil exchange.The first opening 3 being connected to runner 12 being equipped with due to valve rod 1 is the kidney slot of strip, no matter
Whether the thickness H of gear case oil bottom case A changes, and does not influence machine oil and is discharged and injects through runner 12 from the first opening 3 so that
The utility model can adapt to the various gear case oil bottom case A of different-thickness.
