In order to address the above problem, the utility model by the following technical solutions:
The multi-functional valve well lid, comprise big well lid, walling crib and little well lid, big well lid is a circulus, and the ring place is provided with concave station in the big well lid, walling crib is installed on the concave station and by expansion bolt and fixes, and little well lid is installed in the interior ring of walling crib and fixes by the back-up ring that is located at the walling crib bottom.
Compared with prior art, the beneficial effects of the utility model are:
When changing the valve of the big specification in down-hole, big well lid and little well lid can be taken down together, be need not to dig and open road, save the time, reduce the cost of maintenance, good economic benefits and social benefit are arranged.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The multi-functional valve well lid, as shown in Figure 1, comprise big well lid 1, walling crib 2 and The Small Well lid 4, big well lid 1 is a circulus, the ring place is provided with concave station in the big well lid 1, walling crib 2 is installed on the concave station and by expansion bolt 5 and fixes, and The Small Well lid 4 is installed in ring places and fixing by the back-up ring 3 that is located at walling crib 2 bottoms in the walling crib 2.
Valve 6 in well chamber 7 breaks down, and when needing to take out maintain and replace, if the specification of valve 6 is less, only opens The Small Well lid 4 and gets final product; If the specification of valve 6 is bigger, when only opening The Small Well lid 4 and can't take out, big well lid 1 opened together with The Small Well lid 4 gets final product.
