Abstract

The utility model discloses a compression-type filter which comprises a filter main body and a filter end cover, wherein the filter end cover is used for sealing the filter main body, the middle of the filter end cover is provided with a bolt fastener, and the filter end cover is compressed on the filter main body by the bolt fastener. According to the utility model, the filter end cover is compressed on the filter main body by the bolt fastener, so that a good sealing performance can be maintained while the internal pressure of the filter is improved.

Description

A kind of compression type filter

Technical field

The utility model relates to a kind of filter, is specifically related to a kind of compression type filter.

Background technology

Filter is indispensable a kind of device on the pumped (conveying) medium pipeline, usually is arranged on the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment, is used for eliminating the impurity in medium, with the normal use of protection valve and equipment.After entering when fluid the filter cylinder that is equipped with the certain specification filter screen, its impurity is blocked, and the filtrate of cleaning is discharged by filter outlet.Filter comprises that a filter body and is used for the filter end cap of this filter body of sealing, yet the sealing effectiveness of existing filter end cap and filter body usually is affected under high-pressure situations, thereby makes the not compact filter effect variation that causes of sealing between filter end cap and filter body.

The utility model content

For the deficiencies in the prior art, the utility model proposes a kind of compression type filter, the sealing between its filter end cap and filter body is optimized.

In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:

A kind of compression type filter, comprise that a filter body and is used for the filter end cap of this filter body of sealing, and described filter end cap middle part is provided with a bolt fastener, by this bolt fastener, described filter end cap is pressed on filter body.

Preferably, also be provided with sealing ring between described filter end cap and filter body.

Preferably, described bolt fastener comprises a bolt head and a bolt screw rod, and described filter end covers the cavity that is provided be used to holding described bolt head.

Preferably, described bolt head is provided with one and is convenient to the fixed block that described bolt fastener is screwed out.

Compared with prior art, the utility model is pressed on filter end cap on the filter body main body by a bolt fastener, makes it also can keep good sealing property when the filter internal pressure improves.

Description of drawings

Fig. 1 is the structural representation of a kind of compression type filter of the utility model.

Fig. 2 is the dismounting schematic diagram of a kind of compression type filter of the utility model.

The specific embodiment

Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further, so that clearerly understand the utility model technological thought required for protection.

As Fig. 1, be the structural representation of a kind of compression type filter of the utility model, comprise filter body 10 and be used for the filter end cap 11 of this filter body 10 of sealing.

In the utility model, filter end cap 11 middle parts are provided with a bolt fastener 13, and bolt fastener 13 is pressed on filter end cap 11 on filter body 10., for better keeping its sealing property, also a sealing ring 12 can be set between filter end cap 11 and filter body 10.

Bolt fastener 13 comprises bolt head 131 and bolt screw rod 132, and filter end cap 11 is provided be used to the cavity 111 that holds bolt head 131, thereby keeps the attractive in appearance of whole product.

Filter body 10 and filter end cap 11 are for removably connecting, and this is to be positioned at the filter screen of filter body for the ease of cleaning, when needs clean, as long as removable filter device end cap is unloaded to take out, need the filter screen that cleans., for the ease of dismounting, also can be provided with one and be convenient to the fixed block 133 that bolt fastener 13 is screwed out on bolt head 131.

For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and the distortion all should belong to the protection domain of the utility model claim within.
