Description

Technical Field

[0001] The utility model relates to the field of stop valves, in particular to a forged stop valve with a replaceable valve seat. Background Art

[0002] The stop valve is a common type of valve in our lives. The main function of the stop valve is to control the flow. The friction between the sealing surfaces of the stop valve is small during opening and closing, and it is relatively durable, so it is popular among users.

[0003] The Chinese patent application number: CN200820088947.2 provides a stop valve with an improved structure. The valve stem and the valve core are connected as one, so when the valve stem is rotated, there is no need to worry about the valve core falling off from the valve stem due to excessive rotation. At the same time, it saves time and effort when processing and producing the valve stem and the valve core. The valve stem and the valve core are connected as one, so when the valve stem is rotated, there is no need to worry about the valve core falling off from the valve stem due to excessive rotation. At the same time, it saves time and effort when processing and producing the valve stem and the valve core.

[0004] The existing stop valves have certain disadvantages when in use. First of all, the use of the stop valve seat is very important. When the stop valve seat needs to be replaced after long-term use, it is more laborious to open and replace it, and the locking effect of the connection structure is single during daily use, resulting in reduced use effect of the stop valve seat. For this reason, we propose a stop valve with a forged replaceable valve seat. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a forged replaceable valve seat stop valve, which, by setting a positioning block and a clamping piece, presses the clamping piece composed of a spring and a clamping block, and separates the clamping piece from the positioning block under an external force. At this time, the adjusting rod outside the positioning block moves to adjust its position and separate it from the clamping groove, so that the valve seat body can be easily disassembled, thereby improving the convenience of replacement and maintenance of the stop valve, and solving the problem that the valve seat body cannot be easily disassembled and installed; by setting an anti-scouring layer, the anti-scouring layer can form an anti-scouring structure on the outside of the valve seat body, thereby increasing the use effect of the valve seat body and reducing the damage caused by scouring; a movable rod is set, and by pressing the movable rod, the filter element can be easily separated from the main body mechanism, further improving the convenience of maintenance of the stop valve structure.

[0018] Furthermore, the inner end of the filter element is slidably connected to a movable rod, the outer end of the movable rod is sleeved with a spring element, and the lower part of the spring element is movably connected to a guide ring.

[0019] By installing the movable rod, the filter element can be easily separated from the main body mechanism, further improving the convenience of maintenance of the stop valve structure.

[0020] Furthermore, a mounting groove is provided at the outer end of the guide ring, and a connecting component is movably connected to the inner end of the movable rod.

At this time, the adjusting rod outside the positioning block moves to adjust its position and separate from the clamping groove, so that the valve seat body can be easily disassembled, and when the valve seat body is installed, this structure has a good locking effect, which improves the convenience of replacement and maintenance of the stop valve;

[0026] 2. By setting the anti-scour layer, the anti-scour layer can form an anti-scour structure on the outside of the valve seat body, which increases the use effect of the valve seat body and reduces the damage caused by scour;
