Description
Technical field
The utility model relates to a kind of liquid filtering mesh screen.
Background technology
Generally, the fluent material used in spraying coating process field needs higher cleanliness factor, and especially transparency liquid material, therefore material needs to carry out filtering to ensure its cleanliness factor before use.
Filter mesh screen easy to use due to it, good filtration effect and be widely used in spraying coating process.Usually in use filter net cloth easily damages, and the mesh screen wall in other words connector of mesh screen is not easy to damage, and both service lifes do not mate.Be separated because common sieves screen cloth cannot be dismantled with mesh screen wall, filter screen cannot be repaired and change after damaging, and what scrap is not only filter screen, needs to scrap together with mesh screen, thus causes unnecessary waste.
In some implementations, filter screen contains a screen frame, with bolts between screen frame and rack, belongs to a kind of releasable connection, when filter screen damages, directly changes filter screen, and will mesh screen entirety not change.But bolt is connected to during pipeline connects and assembles inconvenience, and dismounting is also inconvenient.
Again in further improved plan, the filter screen with screen frame is assemblied in tube head, and need not depend on other should as structure, thus assembling and convenient disassembly, but it is also lower that bolt connects self efficiency of assembling.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of liquid filtering mesh screen, based on releasable connection, improves the maintainability of liquid filtering mesh screen.
The technical solution adopted in the utility model is:
A kind of liquid filtering mesh screen, comprising:
Top connection is tubular structure, and containing the female upper linkage section of tool, and the inner of internal thread is provided with the axle collar;
Lower contact is tubular structure, and containing having externally threaded lower linkage section, wherein upper binding head is connected with described external screw thread by described internal thread with lower union joint; And
Filter screen is dish, thus be carried on the described axle collar and compress by the termination of described lower union joint.
Aforesaid liquid filters mesh screen, and in certain embodiments, the connection between described upper binding head and described lower union joint is the connection containing seal.
Alternatively, described seal comprises and being arranged on composition surface that filter screen engages with the axle collar, and is arranged on the gasket seal on composition surface that filter screen engages with described termination.
Alternatively, described gasket seal is silica gel pad.
Alternatively, the root of the termination of described top connection and described lower union joint exposed portion structure when internal thread and described external screw thread are tightened is equipped with flange, and on flange, be provided with groove;
Described seal is the O type circle be positioned in described flange.
Alternatively, described upper binding head and lower union joint are provided with the structure interconnected between liquid filtering mesh screen.
According to liquid filtering mesh screen of the present utility model, be connected based on gas thread with lower contact by the top connection of pipe joint structure, convenient disassembly is better.This kind of connected mode is different from bolt and connects, and be bolted to few needs three bolts, not only removal efficiency is low, and in order to ensure sealing, the pretightning force of all bolts must be identical, and assembly difficulty is larger.Simple threaded connection structure is simple, and is easy to sealing, maintainable relatively good.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view according to a kind of liquid filtering mesh screen of the present utility model.
Fig. 2 is a kind of perspective view of liquid filtering mesh screen.
Fig. 3 is a kind of explosive view of liquid filtering mesh screen.
Fig. 4 is a kind of structure principle chart of top connection.
In figure: 1. top connection, linkage section on 11., 12. axle collars, pipeline section on 13., 14. flanges, 15. grooves, 2. lower contact, 21. times linkage sections, 22. lower tube sections, 3. filter screen, 4. lower gasket, 5. Upper gasket.
Detailed description of the invention
In structure as shown in Figure 2, be a kind of perspective view of liquid filtering mesh screen, also can think a kind of single-unit structural representation, should be appreciated that the filtration for liquid can containing multistage, the structure shown in Fig. 2 can think one-level.
Single-stage can separately as filter element in other words to should be appreciated that one-level.
Fig. 4 is visible, mainly adopts pipe joint structure in figure, divides into top connection 1 and lower contact 2, and docking connects.
About top connection 1, be tubular structure, containing upper pipeline section 13 in figure, upper pipeline section 13 structure is changeable, to meet the needs of different application.
The female upper linkage section 11 of top connection 1 tool, and the inner of internal thread is provided with the axle collar 12, the axle collar 12, the axle collar, as loading end, can be used for assembling filter screen 3, also can as other structures, the termination section of such as internal thread.
About lower contact 2, be also tubular structure, Fig. 1 is also containing lower tube section 22, and lower tube section 22 is also changeable, and the assembly structure according to reality is arranged.
Lower contact 2 is containing having externally threaded lower linkage section 21, wherein upper binding head 1 is connected with described external screw thread by described internal thread with lower union joint 2, forms tubular construction syndeton and conveniently connects fast, shown in Figure of description 3, this syndeton directly screws up, and dismounting efficiency is high.
About filter screen 3, then according to pipeline section structure, be configured to as dish, thus be carried on the described axle collar 12 and compress by the termination of described lower union joint 2, complete the assembling of filter screen 3, thus, after top connection 1 and lower contact 2 are taken apart, the access of filter screen 3 can be facilitated.
In addition, pipe connects the convenient sealing of screw thread, and himself can be configured to gas thread on the one hand, structure is simple, and namely self have better sealing function.
In certain embodiments, the bound fraction that pipe connects screw thread is provided with raw material band or packing to form hermetically-sealed construction.
Simple gas thread sealing structure result is slightly poor, and for this reason, preferably, the connection between described upper binding head 1 and described lower union joint 2 is the connection containing seal, thus has better hermetically-sealed construction.
As shown in figs. 1 and 3, described seal comprises and is arranged on composition surface that filter screen 3 engages with the axle collar 12, and the gasket seal be arranged on composition surface that filter screen 3 engages with described termination, gasket seal can use standard component, also can configure voluntarily as required, realize sealing more reliably by extruding.
Preferably, described gasket seal is silica gel pad, and silica gel is soft but waterproof, has certain viscosity, has good sealing.
In certain embodiments, as shown in Figure 4, the root of the termination of described top connection 1 and described lower union joint 2 exposed portion structure when internal thread and described external screw thread are tightened is equipped with flange 14, and is provided with groove on flange.
And then described seal is the O type circle be positioned in described flange 14, form end face seal, hermetically-sealed construction is more simple, easy disassembly.
As previously mentioned, in order to tackle various application, described upper binding head and lower union joint are provided with the structure interconnected between liquid filtering mesh screen.
