Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a prevent spouting formula valve cover, including pipeline 1, pipeline 1's surface threaded connection has valve gap 2, pipeline 1's surface is seted up two spouts 3 that are the symmetric distribution, the inside sliding connection of spout 3 has slider 4, the side fixedly connected with connecting rod 5 of slider 4, valve gap 2's top is rotated and is connected with guard circle 6, be equipped with fixed establishment 8 between guard circle 6 and the connecting rod 5, specifically, fixed establishment 8 makes detachable fixed connection between connecting rod 5 and the guard circle 6, the bottom fixedly connected with protective sheath 7 of guard circle 6, the cross-section of spout 3 is the T shape, slider 4's cross-section is the T shape.

The scheme has the following working processes:

when the valve gap 2 of the pipeline 1 of oil is opened to needs, rotary valve gap 2, make valve gap 2 rise, when meetting the oil eruption, valve gap 2 is dashed and is together jack-up with guard circle 6, guard circle 6 is driven slider 4 through connecting rod 5 after the jack-up and moves in spout 3, then slider 4 is blocked by spout 3, thereby make valve gap 2 can't break through the protection fly-out of guard circle 6 and protective sheath 7, then break away from connecting rod 5 and guard circle 6 through fixed establishment 8, take off valve gap 2, install valve gap 2 on pipeline 1 earlier when installation valve gap 2, be fixed with connecting rod 5 and guard circle 6.

According to the working process, the following steps are known:

make guard circle 6 make valve gap 2 can not the departure lead to personnel injured when valve gap 2 is opened through using connecting rod 5, make connecting rod 5 can unpack apart with guard circle 6 through fixed establishment 8 simultaneously for valve gap 2 can be comparatively convenient take off.

Further, fixed establishment 8 is including offering the holding tank 801 in guard circle 6 bottom, the one end of connecting rod 5 is located the inside of holding tank 801, draw-in groove 802 has been seted up to the inboard of holding tank 801, the inside sliding connection of draw-in groove 802 has fixture block 803, fixture block 803 passes through extrusion spring 804 and draw-in groove 802 elastic connection, the inside of connecting rod 5 is worn to locate by fixture block 803, it is concrete, through inserting connecting rod 5 in holding tank 801, then pass by fixture block 803 and fix, make guard circle 6 can drive connecting rod 5 when removing.

Furthermore, an auxiliary groove 806 is formed in one side of the clamping groove 802, an auxiliary rod 805 is fixedly connected to one side of the clamping block 803, the auxiliary rod 805 penetrates through the auxiliary groove 806, and specifically, when the connecting rod 5 needs to be taken out of the accommodating groove 801, the auxiliary rod 805 slides in the auxiliary groove 806 to drive the clamping block 803 to move, so that the clamping block 803 is separated from the connecting rod 5, and the protection ring 6 is convenient to take up.

Further, slider 4 passes through compression spring 9 and the bottom elastic connection of spout 3, and is concrete, and compression spring 9 makes slider 4 can cushion through compression spring 9 when receiving the pulling force of connecting rod 5, can prevent valve gap 2 departure better.

Further, the surface of the valve cover 2 is provided with a rotating groove 10, and specifically, the rotating groove 10 facilitates the rotation of the valve cover 2 to open the valve cover 2.

Further, the inboard of protective sheath 7 and the surface laminating of valve gap 2, it is specific for valve gap 2 can be by the better protection of protective sheath 7, makes valve gap 2 can not the departure.
