Detailed Description
The present application is not limited to the following examples, and specific implementations may be determined according to the technical solutions and practical situations of the present application.
In the embodiment, as shown in fig. 1 and 2, the liquid ammonium nitrate pump inlet spray guiding device comprises a valve rod 1, a valve body 2 and flanges 3 positioned at two ends of the valve body 2; the inner cavity of the flange 3 and the inner cavity of the valve body 2 form a liquid flow channel; a valve cover 4 is arranged on the valve body 2, a stuffing box 5 is arranged on the valve cover 4, and a valve seat 6 is fixed on the stuffing box 5; a liquid outlet 7 is arranged at the bottom of the valve body 2; the upper part of the valve rod 1 sequentially penetrates through the valve cover 4 and the packing box 5 to form threaded fit with the valve seat 6, and the bottom of the valve rod 1 is provided with a valve core which can move downwards along with the rotation of the valve rod 1 to form partition sealing with the liquid outlet 7.
The upper part of the valve rod 1 is provided with an external thread which is matched with the internal thread of the valve seat 6; axial movement of the valve rod 1 can be realized by rotating the valve rod 1, and the valve core at the bottom is driven to move up and down, so that the liquid outlet 7 can be opened or effective sealing can be formed with the liquid outlet 7; the lower part of the valve rod 1 is a polished rod which is matched with an inner sealing ring of a stuffing box 5 to realize sealing.
This application simple structure, the current gate valve of accessible is reformed transform and is made. The operation is convenient, and the liquid ammonium nitrate can be discharged or normally conveyed only by rotating the valve rod 1; meanwhile, blowing is not needed, material blockage can be effectively avoided, meanwhile, the use of steam is reduced, material splashing is avoided, and the production safety and stability are improved.
As shown in fig. 1 and 2, an annular inclined sealing surface 8 with a large inside and a small outside is arranged at the liquid outlet 7, the valve core comprises a hemispherical hard valve head 9 fixed at the bottom of the valve rod 1 and a soft valve head 10 coated outside the hard valve head 9, and the soft valve head 10 is in a conical shape with a downward vertex.
The generatrix of the cone-shaped soft valve body 2 can also be an arc line which is convex outwards.
During sealing, along with the downward movement of the valve rod 1, the hard valve head 9 extrudes the soft valve head 10 and forms reliable sealing with the inclined sealing surface 8; hemispherical hard valve head 9 and skew seal face 8 be tangent cooperation, and the pressure that hard valve head 9 provided keeps perpendicular with skew seal face 8 like this, thereby it is better to seal the effect more to laminate between soft valve head 10 and skew seal face 8.
As shown in fig. 1 and 2, the liquid outlet 7 is connected with a downward straight connecting pipe 11. Thus being convenient for externally connecting a pipeline and discharging liquid ammonium nitrate.
As shown in fig. 1 and 2, a circle of cutting ring which is coaxially distributed with the liquid outlet 7 is arranged at the bottom of the inner cavity of the valve body 2, two sections of cutting grooves are formed by the cutting ring and the inner wall of the valve body 2, and each section of cutting groove comprises a vertical calibration surface 12 and a horizontal limiting surface 13; at least three support frames 14 are uniformly distributed at the lower part of the valve rod 1 along the circumferential direction; the soft valve head 10 is tightly pressed against the inclined sealing surface 8 corresponding to the hard valve head 9, and the supporting frame 14 is screwed into the cutting ring in a matching way and is seated on the limiting surface 13.
When the valve rod 1 rotates and moves downwards, the support frame 14 firstly falls into the cutting groove to rotate, and the valve head cannot deviate under the action of the vertical calibration surface 12 and can keep moving downwards vertically and start to seal with the liquid outlet 7; after the sealing is finished, the supporting frame 14 is seated on the limiting surface 13, so that on one hand, the downward movement of the valve rod 1 can be ensured, and the sealing reliability is ensured; on the other hand, the valve rod 1 can be ensured not to be rotated excessively, so that the soft valve head 10 is extruded excessively and is damaged.
In addition, when the valve head seals the liquid outlet 7, the support frame 14 can improve the strength of the valve rod 1 and cannot deform when liquid ammonium nitrate is normally conveyed.
As shown in fig. 1 and 2, a lock nut 15 is movably engaged with the valve stem 1 above the valve seat 6. After the hard valve head 9 tightly pushes the soft valve head 10 against the inclined sealing surface 8, the locking nut 15 is tightened to be tightly attached to the valve seat 6, so that the valve rod 1 can be prevented from moving upwards, and liquid ammonium nitrate is prevented from leaking from the liquid outlet 7.
As shown in fig. 1 and 2, a hand wheel 16 is mounted on the top of the valve stem 1. Thus being convenient for operators to operate.
The above technical features constitute the best embodiment of the present application, which has strong adaptability and best implementation effect, and unnecessary technical features can be added or subtracted according to actual needs to meet the needs of different situations.
