Description

Filter end cover
Technical Field
The utility model belongs to the technical field of the filter, concretely relates to filter end cover.
Background
The filter is an indispensable device on a medium conveying pipeline, and is usually arranged at the inlet end of a pressure reducing valve, a pressure relief valve, a constant water level valve and other equipment of a squaring filter. After the filter is provided with the filter cylinder with a filter screen with a certain specification, impurities are blocked, when the filter needs to be cleaned, the filter cylinder can be taken out only by taking out the detachable filter cylinder and then reloading the detachable filter cylinder after treatment, so that the use and maintenance are very convenient. However, the design scheme of the filter element end cover of the existing oil purification filtering equipment mainly adopts flange bolt connection. For some filters with thicker filter elements, the diameter of the filter cylinder body is larger, and in order to ensure that the flange bolt is connected with enough strength, a plurality of bolts are required to be used for installation and fixation during design. So that the filter element end cover needs to spend too much time when being installed or detached, and the working efficiency is reduced. When the bolts are fastened, if all the bolts are applied with uneven force, the sealing is not tight, the sealing element is damaged, and the filter leaks; and the end cover in the prior art has higher manufacturing cost and low economy.
SUMMERY OF THE UTILITY MODEL
To the problem that the above-mentioned background art provided, the utility model aims at: it is intended to provide a filter end cap.
In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
the utility model provides a filter end cover, includes the end cover main part with filtering barrel threaded connection, the end cover main part is equipped with the cavity, the cavity is equipped with the screw thread, the cavity is equipped with the seal groove, cavity central point puts and is equipped with the spring holder, the spring holder disposes the spring, end cover main part an organic whole is connected with the twist plate, the twist plate is equipped with two openings of mutual symmetry, twist plate central point puts and is connected with the cylinder, the cylinder corresponds with the spring holder position, the cylinder is equipped with the gas vent with the spring holder in the lump, the gas vent runs through cylinder and spring holder.
Further, the mouth of the chamber is chamfered, and the design has a guiding function and facilitates the screwing in of the thread.
Further inject, the seal groove disposes the sealing washer, just the sealing washer cross-section is circular, and such design is sealed effectual.
Further limited, the width of the screw plate is 25mm, and the design has good force bearing effect.
Further, friction lines are arranged on the screwing plate, and the design increases friction force and prevents slipping.
Adopt the beneficial effects of the utility model:
1. by adopting the structural design of the utility model, the end cover main body can be screwed in or out conveniently and easily, the operation is convenient, and the appearance is beautiful;
2. by adopting the structural design of the utility model, the end cover main body can be screwed on the filter cylinder body without using bolts, the number of accessories is small, the problem that the filter cylinder body cannot be used due to the lack of accessories is not easy to occur, the sealing is stable, the leakage is not easy to occur, and the sealing effect is good;
3. adopt the utility model discloses a structural design, simple structure is reasonable, low cost, easily manufacturing.
Drawings
The present invention can be further illustrated by the non-limiting examples given in the accompanying drawings;
fig. 1 is a first schematic structural diagram of an embodiment of a filter end cap according to the present invention;
fig. 2 is a schematic structural diagram of a filter end cap according to an embodiment of the present invention;
fig. 3 is a schematic cross-sectional view of an embodiment of a filter end cap according to the present invention;
the main element symbols are as follows:
the end cover comprises an end cover body 1, a cavity 2, threads 21, a sealing groove 22, a spring seat 3, a screw plate 4, a through hole 5, a cylinder 6 and an exhaust port 7.
Detailed Description
In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.
As shown in fig. 1, fig. 2, fig. 3, the utility model discloses a filter end cover, include the end cover main part 1 with filter cylinder body threaded connection, end cover main part 1 is equipped with cavity 2, cavity 2 is equipped with screw thread 21, cavity 2 is equipped with seal groove 22, cavity 2 central point puts and is equipped with spring holder 3, spring holder 3 disposes the spring, end cover main part 1 an organic whole is connected with screw plate 4, screw plate 4 is equipped with two openings 5 of mutual symmetry, screw plate 4 central point puts and is connected with cylinder 6, cylinder 6 corresponds with spring holder 3 position, cylinder 6 is equipped with gas vent 7 with spring holder 3 in the lump, gas vent 7 runs through cylinder 6 and spring holder 3.
In this embodiment, when using a filter end cap, the screw thread 21 is aligned to the filter cylinder by holding the screw plate 4 to rotate, so as to screw the end cap main body 1 and the filter cylinder, and optionally using an auxiliary assembling and disassembling tool to cooperate with the screw plate 4 to enhance the screwing effect, the arrangement of the through hole 5 not only increases the application range of the auxiliary assembling and disassembling tool, but also achieves the effects of reducing weight and saving materials, otherwise, when needing to disassemble, the screw plate 4 is reversely screwed, so as to be integrated, the installation is fast and convenient, and no fittings are needed, the problem that the fittings are lost to cause the installation is avoided, further, the arrangement of the spring seat 3 can limit the position of the spring, so that the spring can better compress and fix the position of the filter element, and the chamber 2 and the sealing groove 22 inside ensure that the sealing effect of the end cap main body 1 is good after the installation, the leakage-proof effect is good, and the exhaust port 7 is used for exhausting the filter, so that the filter can be filled with hydraulic oil, and the using effect is further ensured.
