[0003] Biogas valve well is a well body covered outside biogas valve, for the protection of biogas valve, at present, the biogas valve well sold on market is mostly imported, and its quality is heavy, inconvenient for transportation and opening, and people improve the material of biogas valve well for the need of convenient transportation and use, so the biogas valve well on market is mostly made of high-density polyethylene material, the biogas valve well produced by high-density polyethylene material is light in weight, convenient for staff to carry and open, and has been widely applied at present.

[0004] However, with the deepening of people's application, people find that biogas valve well is placed in outdoor environment for a long time, the surface of well body and well cover body is prone to adhesion after high-density polyethylene material is exposed to sun for a long time and then wetted by rain, so that well cover body is not easy to open.

[0005] Therefore, it is necessary to provide a HDPE pipeline biogas collection special valve well to solve the above problems. UTILITY MODEL CONTENT

[0006] The utility model provides a kind of HDPE pipeline biogas collection special valve well to overcome at least one of the defects (deficiency) described in the prior art.

[0009] The bottom of the valve well cover is equipped with a hook. The valve well body is equipped with a locking device, a linkage limiter, and a linkage connected to the locking device. When the locking device on the valve well body is fastened to the hook on the valve well cover, the locking device drives the linkage to descend and press it against the linkage limiter on the outer wall of the valve well body. When the locking device on the valve well body is opened, the locking device on the valve well body separates from the hook on the valve well cover. At this time, the linkage and the linkage limiter on the valve well body separate simultaneously. The locking device drives the linkage to lift up, thereby separating the valve well cover from the valve well body. By providing an inner groove on the valve well cover, the valve well cover can fit well onto the valve well body through the inner groove. The bottom of the valve cover is equipped with a hook, and the valve cover body is equipped with a locking device and a linkage limiter. Therefore, the locking device on the valve cover body can fasten the hook on the valve cover body to fix the valve cover body.
