Abstract
The sealing ring assembling tool comprises a pressing ring and a positioning shaft, wherein the cross section of the pressing ring is inverted U-shaped, the cross section of the positioning shaft is inverted T-shaped, the surface I of the positioning shaft is in positioning fit with the inner hole surface of a valve seat, the surface II of the positioning shaft is smaller than the inner hole diameter of a sealing ring, the surface III of the positioning shaft is in guiding fit with the inner hole surface of the pressing ring, and hoisting holes are formed in the tops of the pressing ring and the positioning shaft. The tool has the advantages that the tool is simple in structure, low in manufacturing cost and high in practicability, the sealing ring cannot shake or incline in the assembling process, even the sealing ring is forcibly pressed in, the risk of damage of the sealing ring in the assembling process is reduced, the sealing performance of the valve is more reliable, and the assembling efficiency is improved.
Description
Technical Field
The invention relates to a sealing ring assembling tool and a using method thereof.
Background
The sealing between the valve body and the valve seat of the valve is realized by a sealing ring, and the sealing ring is used as the most critical sealing element for the valve, and the installation process of the sealing ring has very strict requirements. The sealing ring is required to be extremely high in surface size precision and surface roughness of the valve seat and the valve body which are in contact with the sealing ring, the valve seat and the valve body are in interference fit, the sealing ring needs to be installed into the valve seat fixer through a special tool on a press during installation, the installation difficulty is high, and sealing failure of the sealing ring can be caused by carelessness during assembly.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides a sealing ring assembling tool and a using method thereof.
The technical scheme is that the sealing ring assembling tool comprises a pressing ring and a positioning shaft, wherein the cross section of the pressing ring is in an inverted U shape, the cross section of the positioning shaft is in an inverted T shape, the surface I of the positioning shaft is in positioning fit with the inner hole surface of a valve seat, the diameter of the outer circle of the surface II of the positioning shaft is smaller than the diameter of the inner hole of the sealing ring, the surface III of the positioning shaft is in guiding fit with the inner hole surface of the pressing ring, and hoisting holes are formed in the tops of the pressing ring and the positioning shaft.
Preferably, the top end of the valve seat, the top end and the bottom end of the positioning shaft and the bottom end of the inner hole surface of the pressing ring are provided with chamfers.
A use method of a sealing ring assembling tool comprises the following steps:
step 1: vertically placing the valve seat assembly below a press;
step 2: the surface I of the positioning shaft is matched with the surface of the inner hole of the valve seat in a positioning way by hoisting;
and 3, step 3: sleeving a sealing ring on the outer circle of the surface II of the positioning shaft;
and 4, step 4: sleeving the inner hole of the pressing ring into the surface III of the positioning shaft by hoisting;
and 5: and slowly and stably pressing the sealing ring by using a press, and delivering the sealing ring to the specified position of the valve seat.
The tool has the advantages that the tool is simple in structure, low in manufacturing cost and high in practicability, the sealing ring cannot shake or incline in the assembling process, even the sealing ring is forcibly pressed in, the risk of damage of the sealing ring in the assembling process is reduced, the sealing performance of the valve is more reliable, and the assembling efficiency is improved.
Drawings
FIG. 1 is a schematic view of the present invention.
In the figure: 1. pressing a ring; 2. positioning the shaft; 3. a valve seat; 4. a seal ring; 201. positioning the surface I of the shaft; 202. positioning the surface II of the shaft; 203. and positioning the surface III of the shaft.
Detailed Description
As shown in the figure, a sealing washer assembly fixture, including clamping ring, location axle, the cross-section of clamping ring is the shape of falling the U, and the cross-section of location axle is the shape of falling T, and the I face and the disk seat hole face location fit of location axle, II out-of-plane diameter of location axle are less than sealing washer hole diameter, and III faces of location axle and the hole face of clamping ring are the direction cooperation, and the clamping ring is equipped with the hole for hoist with the top of location axle. And chamfers are arranged at the top end of the valve seat, the top end and the bottom end of the positioning shaft and the bottom end of the inner hole surface of the pressing ring. The risk that the sealing washer damaged when having reduced the assembly has improved assembly efficiency.
A use method of a sealing ring assembling tool comprises the following steps:
step 1: vertically placing the valve seat assembly below a press;
and 2, step: the surface I of the positioning shaft is matched with the surface of the inner hole of the valve seat in a positioning way by hoisting;
and step 3: sleeving a sealing ring on the outer circle of the surface II of the positioning shaft;
and 4, step 4: sleeving the inner hole of the pressing ring into the surface III of the positioning shaft by hoisting;
and 5: and slowly and stably pressing the ring by using a press, and delivering the sealing ring to the specified position of the valve seat.
The tool is simple in structure principle, low in manufacturing cost and high in practicability, and the sealing performance of the valve is more reliable.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications without inventive contribution to the present embodiment as required after reading the present specification, but all of them are protected by patent law within the scope of the present invention.
