Description
Technical field
The utility model belongs to the antitheft valve pit of a kind of lift-on/lift-off type.
Background technology
Present valve pit adopts concrete structure to build by laying bricks or stones at the scene usually and forms, and the effect of valve pit is that instruments such as underground valve of effectively protection or water meter are avoided infringement.Normally instruments such as underground valve or water meter are trapped among in the well, seal valve pit with well lid again with valve pit.The common volume of ready-made like this valve pit is bigger, water often appears returning in valve pit bottom, also is not easy to handle well very much with the waterproof problem of the concrete structure of valve pipe junction, often has water leakage, cause valve, pipeline and valve pit to ooze for a long time and duck in drink, make valve, pipeline suffer erosion.Also will make the valve pit bulk strength descend owing to invade bubble for a long time, as easy as rolling off a log hidden danger such as cause that paralysis is spoilt, even have an accident.
The valve pit of concrete structure in addition, its valve pit cover plate adopts cement solidification to connect with valve pit usually, and linking intensity is very limited, well lid is often lost, therefore cause the component of valve and instrument stolen or destroyed, making influences the operation of whole pipe network by the valve cisco unity malfunction.
The valve pit of concrete structure only covers the entrance at valve pit and has carried out the insulation processing, and heat insulation effect is undesirable, also regularly safeguards every year usually, has increased workload, has increased many expenses.
The valve pit of concrete structure does not have the well ladder, must descend in the valve pit to carry out when operated valve, and it is extremely inconvenient to work together.In addition because the operating space is little, in valve pit, often occur revealing during operated valve under the excessive or ordinary person at system pressure, cause danger extremely easily.
Summary of the invention
The purpose of this utility model provides the antitheft valve pit of a kind of lift-on/lift-off type, and it is antitheft convenient with open operation that it is had, the safety insulation, and the advantage of service life of equipment can effectively be protected and prolong to corrosion-resistanting waterproofing performance and installation rapidly.For this reason, the utility model adopts: the antitheft valve pit of lift-on/lift-off type is the antitheft valve pit of the sealed lift-on/lift-off type of sidewall and bottom that steel plate is made, the antitheft valve pit upper port of lift-on/lift-off type seals with well lid, well lid is provided with anti-theft bolt, the borehole wall corresponding with the manhole cover anti-theft bolt is provided with the support locknut, be provided with open hole with the well lid of the valve lever vertical upper of valve in the well, open hole seals and opens with antitheft port lid, valve extension rod lower end connects valve lever, valve extension rod upper end is arranged in open hole, the borehole wall is provided with pipeline and penetrates the hole, and the outer upper end of the borehole wall is provided with hanger, is provided with sealing ring between borehole wall upper end and the well lid.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that to have antitheft and open operation convenient, the safety insulation, the advantage of service life of equipment can effectively be protected and prolong to corrosion-resistanting waterproofing performance and installing rapidly, and also have simple in structurely, and cost is low, advantage easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
As shown in Figure 1, the antitheft valve pit of a kind of lift-on/lift-off type, formed by valve 17 and well lid 8, the antitheft valve pit of lift-on/lift-off type is sidewall and the antitheft valve pit of bottom 16 sealed lift-on/lift-off types that steel plate or steel pipe are made, the antitheft valve pit upper port of lift-on/lift-off type seals with well lid, well lid is provided with anti-theft bolt, the borehole wall corresponding with manhole cover anti-theft bolt 7 is provided with and supports locknut 10, when well lid is fastened on well head, each manhole cover anti-theft bolt just in time is arranged in the support locknut that the corresponding borehole wall is provided with, tighten the manhole cover anti-theft bolt in supporting locknut, promptly lock well lid and be used for antitheft.Be provided with sealing ring 6 between manhole cover anti-theft bolt and the well lid, anti-sealing infiltrates in the well.Be provided with open hole 5 with the well lid of valve lever 12 vertical upper of valve in the well, open hole is with antitheft port lid 4 sealings and open.Antitheft port lid periphery is spirally connected with the open hole periphery, and antitheft port lid periphery and lower end and open hole periphery and lower end are provided with sealing ring 3, and anti-sealing infiltrates in the well.
The outer end is provided with corrosion-inhibiting coating 19 in the described borehole wall and the bottom, for example scribbles waterproof paint etc. and is used for antiseptic and rustproof and moistureproof.Described well lid lower end is provided with insulation layer 2, for example is provided with heat-preservation cotton and is used for insulation, prevents freezing instrument water meter.For convenient valve pit up and down can be provided with well ladder 13 in the borehole wall.Pressure relief valve 18 is arranged on the pipeline of well and is convenient to mounted valve.
During use, the utility model is finished at produce in factory, lifting is transported to the job site and pipeline is penetrated the hole from pipeline penetrates in the well and be connected with valve then, again tube circumference and pipeline are penetrated hole periphery welded seal, then open antitheft port lid if need to open and close valve, promptly expose the square toes of valve extension rod upper end in the open hole, turn square toes with instrument and promptly finish Open valve, get final product if need to repair valve and open well lid.
In a word, it is convenient to the utlity model has antitheft and open operation, the safety insulation, and the advantage of service life of equipment can effectively be protected and prolong to corrosion-resistanting waterproofing performance and installing rapidly, and have simple in structurely, and cost is low, advantage easy to use.
