Abstract

The utility model relates to a special tool for installing valve seal rings, which aims to overcome the disadvantages of time and labor waste, low working efficiency, raw material waste, high maintenance cost and affect on normal production by using the common tool to install the valve seal rings in the prior art. The tool is two semicircular tiles which form a cylinder after being clipped together, the outside diameter of the cylinder formed after the two semicircular tiles are clipped is identical with the outside diameter of the seal rings of the pipe valve, and the length of the tiles is larger than the depth of the bushing of the seal rings; handles are oppositely fixed at one end of the outer circular surfaces of the two semicircular tiles. Because the special tool for installing thevalve seal rings is cylinder shaped after the two semicircular tiles are clipped together, the seal rings are pushed inward by the cylinder shaped tool and installed in the bushing of the valve, so that the stress to the circumference is uniform, and the sealing effect is good; the seal rings are mutually close, therefore, the oil leakage during the installation process is small; due to good sealing effect, the overhaul to the valve can be carried out according to the plan without influencing the normal production, with low maintenance expense.

Description

Valve seat rings installs specific purpose tool additional
Technical field
The utility model belongs to instrument, specifically a kind of specific purpose tool that installs valve seat rings on the valve of oil pipeline additional.
Background technology
Valve on the oil pipeline is generally installed on vertical duct.In order to guarantee that its sealing prevents leakage of oil, to install many roads sealing ring on the pipeline valve additional, for example the AUTCO valve will install more than ten sealing ring additional continuously in seal ring set.
The instrument of prior art mounted valve sealing ring, usefulness be to resemble the general tool that this head such as screwdriver is flat and bar portion is long.During operation, in the sealing ring sleeve that pushes dress sealing ring on the valve one by one, use anchor ring one week of above-mentioned general tool along each sealing ring again, one even installs more than ten, and sealing ring is shifted onto in the sleeve successively.Owing to use above-mentioned instrument will change the pushing of circle along the plane of sealing ring, each used thrust is impossible balance on circumference, therefore can cause the sealing ring breakage because of the border unbalance stress of sealing ring, not only wasted sealing ring, also the ring of breakage to be taken out refitting, waste time and energy inefficiency; Simultaneously, when using above-mentioned general tool and installing, because the border causes between the sealing ring by not tight because of unbalance stress, ring spacing is big does not reach the effect of sealing; Moreover, in the process of installing,, pollute and waste because of finally making the valve leakage of oil to sealing ring pushing injustice.
In sum, with above-mentioned unreliable with general tool mounted valve seal ring seal, leakage of oil waste raw material, contaminated environment waste time and energy, work efficiency is low, and maintenance cost increases, and has also influenced normally carrying out of oil transportation work.
The utility model content
Technical problem to be solved in the utility model is, it is unreliable with general tool mounted valve seal ring seal to overcome prior art, leakage of oil waste raw material, contaminated environment, and waste time and energy, work efficiency is low, the maintenance cost height, influence the shortcoming of ordinary production, provide a kind of valve seat rings to install specific purpose tool additional.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: described instrument is two and snaps together and become semicircle tile cylindraceous, outside diameter of cylinder after described semicircle tile fastens is identical with the sealing ring external diameter of pipeline valve, and its length is greater than the ring set degree of depth of dress sealing ring; End at two semicircle tile peripheries is fixed with handle respectively perpendicular to periphery.
The utility model also has following technical characterictic:
The manner of described two semicircle tiles is, the both sides in two semicircle tile junctions, and being respectively equipped with to be superimposed together up and down connects the last lower ear plate of usefulness, and hold-down bolt vertically passes lower ear plate it is tightened together;
On described nearly handle one end face that snaps together two semicircle tiles, be provided with the pillar that can insert sealing ring gland end face relatively perpendicular to end face.
During use, a plurality of sealing rings are packed in the ring set of valve seat rings successively, pack into two semicircle tiles of an end band handle in the ring set relatively and snap together, two hold the anchor ring that handle pushes each sealing ring, sealing ring all can be packed in the ring set, the gland of the sealing ring outer end of screwing on then gets final product.
Advantage of the present utility model and good effect are, because the specific purpose tool of described mounted valve sealing ring, be to become cylindric after two semicircle tiles snap together, inwardly push pack into the ring set of valve of sealing ring with specific purpose tool cylindraceous, make a border of sealing ring evenly stressed, can reach the effect of sealing after the installation; Simultaneously, sealing ring is evenly stressed to make it lean on tightly each other, and the leakage of oil amount is few in the process of installation; Because good sealing effect, the valve maintenance can be carried out according to plan, does not influence the normal oil transportation of petroleum pipeline, and what ensure safety in production effectively carries out.After using above-mentioned instrument, became 1 to 2 hour, high efficiency by original about 3 to 4 hours maintenance time; Because installation effectiveness height, leakage of oil amount are few, thereby have saved maintenance cost and time, environmental pollution also alleviates greatly.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, the specific purpose tool of mounted valve sealing ring is, left and right two snap together right semi-circle tile 1.1 and the left semicircle tile 1.2 (referring to Fig. 2) that becomes cylinder 1 shape, cylinder 1 after two semicircle tiles 1.2 and 1.1 fasten about described, its external diameter is identical with the sealing ring external diameter of pipeline valve, and its length is greater than the ring set degree of depth of dress sealing ring; About an end of two semicircle tiles 1.2 and 1.1 peripheries, perpendicular to the opposing handle 2 that is fixed with of periphery.
Two semicircle tiles 1.2 and 1.1 manner are about described, about two semicircle tiles 1.2 and 1.1 be fastened and connected the place both sides, being respectively equipped with to be superimposed together up and down connects the left otic placode 1.2 1 and the auris dextra plate 1.11 of usefulness, otic placode is provided with the vertical core that communicates up and down after superimposed, hold-down bolt 5 vertically passes the vertical core on left otic placode 1.21 and the auris dextra plate 1.11, and it is tightened together.
In order to increase the function of described specific purpose tool, on nearly handle 2 upper surfaces of described two semicircle tiles 1.2 and 1.1, the vertical relative bearing 3 that is provided with end face is erect on the bearing 3 to be fixed with and just can be inserted the pillar 4 in the groove on the existing sealing ring gland end face.After using described specific purpose tool that sealing ring is all pushed the ring set of sealing ring, the sealing ring gland of screwing on turns described instrument around, and top pillar 4 is inserted in the groove on the sealing ring gland end faces, use as the spanner of twisting gland, make between the sealing ring further to be close to.
The utility model is not only applicable to the installation of valve seat rings on the described oil pipeline, is applicable to the installation of seal that all seal clearances are little and cover piece installing yet.
