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. 1-5, a petroleum pipeline buries ground valve gland, including valve body 1, the top bolt fixedly connected with valve gap 2 of valve body 1, the top welding of valve body 1 has fixed plate 3, and fixed plate 3 up end fixedly connected with inner cover 4, the outside sliding sleeve of inner cover 4 has a plurality of dustcoats 5 one by one, preferred inner cover 4 and dustcoat 5 all adopt the ya keli board material, when self can not the corrosion, can not lead to the fact the influence to the valve, and the sliding sleeve setting between two adjacent dustcoats 5, the top joint of dustcoat 5 has roof 6, and roof 6 passes through bolt 8 and 5 fixed connection of dustcoat in the outside.

Specifically, as shown in fig. 1-3, the plane of depression of the inner cover 4 and the outer cover 5 is both rectangular frame-shaped, and a rubber ring 11 is arranged between the inner cover 4 and the outer cover 5, and the rubber ring 11 is in interference fit with the inner cover 4 and the outer cover 5, and a rubber ring 11 is arranged between the adjacent outer covers 5, and the rubber ring 11 is in interference fit with the outer covers 5 on both sides, so that the sealing between the cover plates is realized through the rubber ring 11.

Specifically, as shown in fig. 2, fig. 4 and fig. 5, dustcoat 5 longitudinal section all is the structure of falling L, and dustcoat 5's horizontal end distance equals dustcoat 5's thickness, a plurality of buckles 7 of fixedly connected with on the lower terminal surface of roof 6, and the top edge department joint of a plurality of buckles 7 and dustcoat 5, buckle 7 is the right trapezoid structure, and trapezoidal longer base is located the top, the hypotenuse sets up towards the outside, and roof 6 is through screw thread fixed connection between a plurality of bolts 8 and the dustcoat 5, spout 9 has all been seted up on each face in the outside of inner cover 4 and dustcoat 5, and the inside slip of spout 9 has slider 10, and fixed connection between the inner wall of slider 10 and dustcoat 5, spout 9 and slider 10 cross-section all are T shape structure, and have certain damping between spout 9 and the slider 10.

Specifically, as shown in fig. 3, the four corners of the upper end surface of the fixing plate 3 are fixedly connected with zinc blocks 12, preferably made of a metal which is more active and cheaper than the valve.

The working principle is as follows: after the valve body 1 is installed, the outer cover 5 positioned outside the inner cover 4 is pulled upwards, the outer cover 5 slides to the upper side of the inner cover 4 through the sliding of the sliding block 10 in the sliding groove 9, meanwhile, due to the fact that certain damping exists between the sliding block 10 and the sliding groove 9, the outer cover 5 is prevented from sliding downwards in the sliding process, after the outer cover 5 is arranged, the top of the outer cover 5 at the top is clamped with the top plate 6, the clamping between the top plate 6 and the outer cover 5 is achieved through the clamping buckle 7, the outer cover 5 and the top plate 6 are fixed through the bolt 8, the stability of the cover plate structure is guaranteed, due to the fact that the rubber rings 11 are arranged between the inner cover 4 and the outer cover 5 and between two adjacent outer covers 5, the sealing of the inner valve body 1 can be achieved through the cover plate, and the stability of the valve body 1 is improved; when the inside leakage that takes place the moisture of cover plate, because form the galvanic cell structure between the iron material of zinc piece 12 and valve body 1, and the liveness of zinc piece 12 is greater than iron, carry out the cathodic protection of sacrificial anode, corrode zinc piece 12 promptly to guarantee that valve body 1 structure is intact, further promote the stability of valve body 1, when the change that needs carry out valve gap 2 or zinc piece 12, promote dustcoat 5 to primary position department, can carry out convenient operation to valve gap 2 or zinc piece 12 promptly.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
