Description
Technical Field
The utility model relates to the technical field of valves, more specifically say, it relates to a filter relief pressure valve.
Background
The pressure reducing valve is a valve which reduces the inlet pressure to a certain required outlet pressure through regulation and leads the outlet pressure to be automatically kept stable by relying on the energy of the medium. From the viewpoint of hydrodynamics, the pressure reducing valve is a throttling element with changeable local resistance, namely, the flow speed and the kinetic energy of fluid are changed by changing the throttling area to cause different pressure losses, thereby achieving the purpose of pressure reduction; pressure reducing valves typically achieve a pressure reducing effect by providing a pressure reducing device within the valve fluid passageway.
In order to achieve the effect of pressure reduction, the fluid flowing area of the fluid channel is reduced, so that impurities in the fluid are easy to accumulate in the fluid channel to form dirt and block the fluid channel; often, in order to solve the problem that impurities are accumulated in the fluid channel to form dirt, people install a filtering device on a pipeline system, so that a medium is filtered by the filtering device before flowing into the fluid channel of the valve; however, the existing method needs to install the pressure reducing valve and the filtering device on the pipeline system, which brings trouble in installation, and the filtering device installed in the pipeline system has the problem of inconvenient maintenance.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model aims to provide a filtering pressure reducing valve;
in order to achieve the above purpose, the utility model provides a following technical scheme:
a filtering pressure reducing valve comprises a valve body provided with a fluid inlet and a fluid outlet; the valve body is provided with a fluid channel, the valve body is provided with a fluid inlet, and the side wall of the valve body is tightly attached to the fluid inlet.
When fluid flows in from the fluid inlet, the fluid firstly flows in from one side of the filter screen, then flows out from the other side of the filter screen and enters the fluid channel.
The utility model discloses further set up: the valve body is provided with a mounting hole, one end of the filter screen is arranged in the mounting hole, the other end of the filter screen extends upwards and is arranged in the fluid channel, and the filter screen is fixed on the valve body through a fixing screw and the mounting hole in a threaded connection mode.
The utility model discloses further set up: the filter screen is cylindrical.
The utility model discloses beneficial effect: the filter screen is arranged at the fluid inlet and is tightly attached to the side wall of the fluid inlet, so that fluid flowing in from the fluid inlet passes through the filter screen and then enters the fluid channel, impurities in the fluid are blocked outside the fluid channel by the filter screen in the process, the filtering effect is achieved, and the impurities are prevented from being accumulated into dirt in the fluid channel; after the pressure reducing valve is installed on a pipeline system, a filtering device does not need to be additionally installed on the pipeline system; thereby saving the installation space on the pipeline system, reducing the installation times on the pipeline system and saving the installation time; in addition, the filter screen in the pressure reducing valve is convenient to disassemble and assemble, so that the pressure reducing valve is convenient to maintain.

Detailed Description
An embodiment of a filtering pressure reducing valve according to the present invention will be described in further detail with reference to fig. 1 to 5.
A filtering pressure reducing valve comprises a valve body 1 provided with a fluid inlet 11 and a fluid outlet 12; the valve body 2 is arranged in a fluid channel of the valve body 1, so that the installation space of the filter screen 2 on a pipeline system is saved, and the side wall of the filter screen 2 is tightly attached to the fluid inlet 11; after the fluid flows in from the fluid inlet 11, the fluid is ensured to flow into the fluid channel after passing through the filter screen 2, and the fluid is prevented from entering the fluid channel without the filtering effect of the filter screen 2, so that the condition that the fluid channel is blocked by impurities is avoided, and the pressure reducing valve is protected better.
When fluid flows in from the fluid inlet 11, the fluid flows in from one side of the filter screen 2, flows out from the other side of the filter screen 2, enters the fluid channel, and finally flows out from the fluid outlet 12.
The filter screen 2 is arranged at the fluid inlet 11, so that fluid flowing in from the fluid inlet 11 firstly passes through the filter screen 2 and then enters the fluid channel, impurities in the fluid are blocked outside the fluid channel by the filter screen 2 in the process, the filtering effect is achieved, and the impurities are prevented from being accumulated into dirt in the fluid channel; after the pressure reducing valve is installed on a pipeline system, a filtering device does not need to be additionally installed on the pipeline system; thereby saving the installation space on the pipeline system, reducing the installation times on the pipeline system and saving the installation time; in addition, the filter screen 2 in the pressure reducing valve is convenient to disassemble and assemble, so that the pressure reducing valve is convenient to maintain.
The valve body 1 is provided with a mounting hole 13, one end of the filter screen 2 is arranged in the mounting hole 13, the other end of the filter screen extends upwards and is arranged in the fluid channel, and the filter screen 2 is fixed on the valve body 1 through the fixing screw 3 and the mounting hole 13 in a threaded connection mode, so that the filter screen 2 is more stably fixed in the valve body 1; when the valve body 1 and the filter screen 2 need to be cleaned, only the fixing screws 3 are screwed out of the mounting holes 13, and the filter screen 2 is taken out of the mounting holes 13; the filter screen 2 is very convenient to disassemble, assemble and clean.
The filter screen 2 is cylindrical, so that the fluid passing through the filter screen 2 can be filtered twice, and the fluid is cleaner; the valve is more effectively protected, and the service life of the valve is prolonged.
The above is only the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention; it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
