Embodiment Construction
[0010] attached figure 1 A specific embodiment of the invention is given. A combined one-piece filter check valve includes a filter and a check valve.
[0011] The filter is a vertical filter screen filter, including a cylinder body 12, a cylinder chamber 13, a cylinder filter screen 14, a water outlet 19, and a sewage outlet 18, and the top of the cylinder body is equipped with a detachable inlet through an elbow bolt 17. A water elbow 15, the upper end of the elbow is a water inlet 16, and one side of the lower part of the cylinder body is provided with a water outlet 19.
[0012] The check valve is a spool lifting check valve, including a valve body 1, a valve cavity 2, a valve seat 3, a valve core 4, a valve stem 5 integrated with the valve core, a valve stem guide chamber 6, and a valve body outlet 10. A detachable valve cover 7 is installed on the top of the valve body through bolts 9 and gasket 8, and a water outlet 19 is set on the lower side of the valve body.

The invention discloses a combined integrated filtering check vale and relates to a fluid pipeline valve device. The combined integrated filtering check vale comprises a vertical cylinder type sieve filter and a spool-lifted check valve. The filter comprises a cylinder body, a cylinder cavity, a cylinder type sieve, a water inlet elbow, a water inlet, a water outlet and a drain outlet. The check valve comprises a valve body, a valve cavity, a valve seat, a spool, a valve stem, a valve stem guiding cavity, a valve bonnet, a water outlet and a water inlet. The vertical cylinder type sieve filter and the spool-lifted check valve are parallelly combined, and the water outlet 19 on one side of the lower portion of the vertical cylinder type sieve filter is connected with the water inlet 20 at the bottom of the spool-lifted check valve via an elbow tube 11 with the radian at 90 degrees. The spool 4 is made of Teflon, copper powder, graphite, corundum powder and silicate cement adhesive via mixing, blanking and high-temperature sintering. The combined integrated filtering check valve has the advantages that existing separated check valve and filter are respectively improved and combined integrally, double functions of filtering and return-stopping are provided, production and mounting cost is reduced, pipeline equipment is simplified, mounting, maintenance and utilization are facilitated, and effect is good.
Description
Technical field: [0001] The invention relates to a fluid filter and a valve, and mainly relates to an integrated fluid filter check valve. Background technique: [0002] The fluid pipeline system, especially the steam condensate recovery pipeline system, the water inlet of the condensate recovery compressor is connected with a check valve, and the water entering the check valve must be connected to the steam equipment through a filter to ensure the safe operation of the condensate recovery compressor And feed water to the boiler to ensure the quality of water supply. Existing check valves and filters are separate single devices, which are installed and used in series through pipelines, which not only increases the cost of accessories such as pipelines, flanges, and gaskets, but also increases the trouble and inconvenience of installation and maintenance. . Furthermore, the existing check valve has short service life and high noise. Invention content: [0003] The object...
