Description

Technical Field

[0001] The present application relates to the technical field of valves, and in particular to a filter pressure reducing valve. Background Art

[0002] The filter pressure reducing valve is a pressure reducing valve with a filter component added to it. It not only ensures the stability of the output air pressure but also filters the air source, such as removing impurities such as oil, water, and dust from the compressed air. This can increase the service life of pneumatic components and the precision of regulating air pressure. The patent name in the prior art is a mini filter pressure reducing valve (application number 2014203046252), which includes a valve body, a valve cover, a water storage cup and a diaphragm. An upper chamber is formed between the valve body and the diaphragm, and a lower chamber is formed between the valve body and the water storage cup. An adjusting handwheel is provided on the valve cover, and an adjusting screw and an adjusting nut are provided in the valve cover. A filtering mechanism is fixed in the water storage cup. A fixing seat is installed in the valve body, and a through hole is provided on the fixing seat for connecting the upper chamber and the lower chamber. A valve core is provided between the fixing seat and the valve body. A push rod is formed at the bottom of the diaphragm, and the bottom end of the push rod passes through the through hole and abuts against the top of the valve core. The filtering mechanism includes a cyclone blade, a one-piece filter element and a valve core. The one-piece filter element includes a filter element body and a threaded connection part integrally formed on the filter element body. The filter element body is connected to the valve body through the threaded connection part. From the above description, it can be seen that under the action of the filter element body, impurities in the compressed air can be filtered out. However, when there are too many impurities in the compressed air, only the filter element body in the pressure reducing valve filters the compressed air, making the cleanliness of the gas blown out of the air outlet of the pressure reducing valve low.

This improves the cleanliness of the air blown out of the valve body's air outlet, meeting the working requirements of the pneumatic components.

[0014] 2. When the filter disc does not need to filter, rotate the filter disc so that the lower end of the mounting bracket is in an open state, thereby adapting to the needs of different pneumatic components;

[0015] 3. When installing the filter disc in the mounting frame, the multiple slides of the fixing ring are respectively inserted and slidably fixed in the multiple locking grooves, thereby improving the convenience of installing the filter disc. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] The embodiment of the present application discloses a filter pressure reducing valve.

[0022] Reference Figure 1 , including a valve body 1, a water storage cup 2, a cyclone blade 3 and a filter body 4. The open end of the water storage cup 2 is threadedly connected to the lower end of the valve body 1. The cyclone blade 3 is annular and is sleeved and fixed on the outer peripheral side of the upper end of the filter body 4. The upper end of the filter body 4 is threadedly fixed to the inside of the lower end surface of the valve body 1. The filter body 4 and the cyclone blade 3 are located in the water storage cup 2.

[0023] Reference Figure 2 and Figure 3 A mounting bracket 5 is inserted into the upper end of the filter body 4 and is cylindrical. A fixing ring 6 is integrally provided on the upper end of the mounting bracket 5 . The lower end surface of the fixing ring 6 is in contact with the upper end surface of the filter body 4 .

[0024] Four slides 7 are evenly fixed to the lower end surface of the fixing ring 6 by bolts. The vertical section of the slide 7 is an isosceles trapezoid. Four locking grooves 8 are evenly opened on the upper end surface of the filter body 4. The locking grooves 8 are composed of sliding grooves and fixing grooves. The sliding grooves are for the slide 7 to be inserted, and the fixing grooves are for the slide 7 to slide horizontally and be fixed.
