Description

Anti-freezing and anti-explosion filter

Technical Field

The utility model relates to an anti-freezing and anti-explosion filter.

Background

The existing filter is easy to frost crack due to the expansion of the internal volume of the ice in a low-temperature environment, so that water leakage of products is caused, and property loss of users is caused. One of the methods for solving the frost cracking problem of the existing products in the market is to use high-strength materials as the filter shell, so that the material cost is high, such as PA12 materials, the requirement on the forming process is high, and the filter shell still cracks after being frozen twice or more. The other method for solving the problem of frost cracking of the existing products in the market is to adopt a method of internal volume deformation, a space which is not communicated with water is isolated in advance in the products, and the space is used for accommodating the volume increased by ice when the water is frozen, so that the destructive power generated when the volume is expanded is weakened; the method has the advantages of complex structure, high requirement on internal sealing performance, difficult assembly, high cost and incapability of being reused.

The existing filter can be damaged due to freezing, and the water hammer can also damage the existing filter, so that the product is cracked and leaks water, and property loss is caused to an end user.

the utility model provides an anti-freezing explosion-proof filter, includes filter body, this internal pressure relief device that is provided with of filter, pressure relief device is including the pressure release seat, be provided with the wash port on the pressure release seat, still be provided with on the pressure release seat and be used for drainage and carminative pressure release hole, the wash port still is connected with sealing element through a pressure release ejector pin cooperation, still the cover is equipped with elastic element on the pressure release ejector pin.

In an embodiment of the present invention, the drain hole is disposed at a center of the pressure relief seat.

In the embodiment of the utility model, the pressure relief hole is arranged at the side edge end of the pressure relief seat.

In the embodiment of the utility model, ribs are arranged on the peripheral wall of the pressure relief ejector rod.

In the embodiment of the utility model, the ribs are distributed in an annular array.

In the embodiment of the utility model, the pressure relief device further comprises a pressure relief cover, and a fixing part for fixing the elastic element is arranged in the pressure relief cover.

The anti-freezing and anti-explosion filter has the following beneficial effects:

1. through the pressure relief device arranged in the filter, particularly comprising a pressure relief seat, a sealing element, a pressure relief ejector rod and an elastic element, the accident that the filter bursts due to icing or water hammer effect in the filter is prevented, and the use safety is ensured.

2. Through the pressure relief device who sets up in the filter, the discharge leads to the water that the volume increases because of freezing to avoid the casing to bear big bulging force, make whole group's filter can reuse.

3. The peripheral wall annular array of pressure release ejector pin distributes and has the rib, and its cooperation with the pressure release seat makes has great water passing space between the two, makes things convenient for the discharge pressure release of rivers.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.

Referring to the attached drawings of the specification, an anti-freezing and anti-explosion filter comprises a filter body 100, wherein a pressure relief device 200 is arranged in the filter body 100, the pressure relief device 200 comprises a pressure relief seat 10, a drain hole 11 is arranged on the pressure relief seat 10, the drain hole 11 is arranged at the center of the pressure relief seat 10, a pressure relief hole 12 for draining and exhausting is further arranged on the pressure relief seat 10, the drain hole 11 is further connected with a sealing element 30 in a matching manner through a pressure relief ejector rod 20, an elastic element 40 is further sleeved on the pressure relief ejector rod 20, the elastic element 40 drives the pressure relief ejector rod 20 to seal the sealing element 30 and the drain hole 11 to close water in a normal state, and the pressure relief ejector rod 20 is ejected out only when the internal pressure of the filter is greater than the pressure of the elastic element 40, so that the drain hole is opened to realize water drainage, and the anti-freezing and anti-explosion filter adopts the structure design, the filter has the advantages that the filter is prevented from bursting due to icing or water hammer effect in the filter, and the use safety of users is ensured.

Further, pressure release hole 12 sets up in the side end of pressure release seat 10, and is more specific, be provided with rib 21 on the periphery wall of pressure release ejector pin 20, just rib 21 annular array distributes, and its aim at, pressure release ejector pin 20 can reciprocate in pressure release seat 10, and pressure release ejector pin 20's rib exists to make and there is great space rather than between the complex pressure release seat 10 for can better wherein outflow of water, carry out the pressure release.

Further, the pressure relief device 200 further includes a pressure relief cover 50, and a fixing portion 51 for fixing the elastic element 40 is disposed in the pressure relief cover 50.

In normal state, the pressure relief push rod 20 firmly pushes the sealing element 30 to tightly match with the water drainage hole 11, so as to realize the blocking effect and keep the water closed. When water in the filter freezes, the internal pressure is larger than the elastic force due to volume expansion in the freezing process, at the moment, the elastic element 40 is compressed, the pressure relief ejector rod 20 moves downwards, the sealing element 30 is ejected to be separated from the drain hole 11, water can flow out of the internal filter, the internal water quantity is reduced, after the water quantity is reduced, the water can continue to freeze, the expansion force generated after the internal water freezes is reduced, and the outer wall of the filter is not prone to spalling. Moreover, the product is in the use, because of the switch is closed, water can form high pressure in the twinkling of an eye and assault the product outer wall, and long-time use, continuous impact makes the outer wall produce the crack easily, consequently the pressure relief device who comprises structures such as elastic element 40 in this filter can cushion the impact of water hammer impact force to the outer wall greatly, has strengthened the life of product.
