The plunger pump is an important device of a hydraulic system and is commonly used for conveying viscous materials with poor fluidity, such as sludge, wet ash and the like. The existing plunger pump is mostly of a double-cylinder cone valve structure, feeding and discharging of materials in a material conveying cylinder are adjusted through mutual switching of two cone valve oil cylinders, and the sealing performance of a cone valve directly influences the pumping pressure of the cone valve type plunger pump and the service life of the cone valve. The existing cone valve has poor sealing effect because the components of materials such as sludge are complex and contain granular and fibrous impurities.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a cone valve seal structure of cone valve plunger pump.
A cone valve sealing structure of a cone valve plunger pump comprises a conveying material cylinder, a cone valve arranged in the conveying material cylinder and a cone valve oil cylinder used for driving the cone valve; a cone valve seat used for being matched and sealed with the cone valve is arranged in the material conveying cylinder;
the cone valve comprises a sealing seat, a sealing ring and an adjusting seat; the sealing seat is fixedly connected with a piston rod of the cone valve oil cylinder through a fixing screw rod; the adjusting seat is in threaded connection with the sealing seat, and an annular groove for accommodating the sealing ring is formed between the adjusting seat and the sealing seat; and the sealing seat and the sealing ring are both provided with outer conical surfaces which are matched and sealed with the conical valve seat.
Preferably, the seal receptacle is wear-resisting metal material, the sealing washer is elasticity non-metal material, just the outer conical surface of sealing washer is slightly higher than the outer conical surface of seal receptacle.
Preferably, the cone valve further comprises a gland, and the gland is fixed to one side, far away from the cone valve oil cylinder, of the sealing seat through a fixing screw rod.
The utility model has the advantages that: 1. the matching surface of the cone valve and the cone valve seat is set to be a conical surface, double-layer sealing is performed by using the sealing seat and the sealing ring, the sealing pressure is high, and the sealing performance is good; 2. the sealing ring and the sealing seat are pressed and fixed by the adjusting seat, and the distance between the adjusting seat and the sealing seat can be adjusted according to the use condition of the sealing ring, so that the sealing reliability is ensured; meanwhile, the sealing ring is convenient to disassemble and replace, and the service life of the cone valve is prolonged.

fig. 2 is a schematic structural diagram of a cone valve in an embodiment of the present invention;
the figures in the drawings represent:
1. the device comprises a conveying cylinder 2, a cone valve 21, a gland 22, a sealing seat 23, a sealing ring 24, an adjusting seat 25, a fixing screw rod 3, a cone valve seat 4 and a cone valve oil cylinder.
Detailed Description
The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the present invention, and do not indicate or imply that the device or element indicated must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
As shown in fig. 1, the cone valve sealing structure of the cone valve plunger pump comprises a conveying material cylinder 1, wherein a cone valve 2 and a cone valve seat 3 matched and sealed with the cone valve 2 are arranged in the conveying material cylinder 1, and a cone valve oil cylinder 4 is installed at the bottom of the conveying material cylinder 1. The cone valve seat 3 is fixedly connected with the conveying cylinder 1, and the cone valve 2 can move towards the cone valve seat 3 under the driving of the cone valve oil cylinder 4.
The structure of the cone valve 2 is shown in fig. 2, and includes a gland 21, a sealing seat 22, a sealing ring 23 and an adjusting seat 24, wherein the sealing seat 22 is made of a wear-resistant metal material, and the sealing ring 23 is made of an elastic non-metal material. The sealing seat 22 is fixedly connected with a piston rod of the cone valve oil cylinder 4 through a fixing screw rod 25, and the gland 21 is fixed on the upper side of the sealing seat 22 through the fixing screw rod 25. The adjusting seat 24 is in threaded connection with the sealing seat 22, and an annular groove for accommodating the sealing ring 23 is formed between the adjusting seat 24 and the sealing seat 22. The sealing seat 22 and the sealing ring 23 are both provided with an outer conical surface which is matched and sealed with the conical valve seat 3, and the outer conical surface of the sealing ring 23 is slightly higher than that of the sealing seat 22.
