Description
[technical field]
The utility model relates to a kind of valve arrangement, is specifically related to a kind of buried soft seal formula gate valve, belongs to valve technology field.
[background technique]
The valve of existing technology is embedded in underground usually through valve well, therefore, needing down in the valve well could switch valve, causes and uses inconvenience.
Simultaneously, the construction cost of valve well is higher, and the casting iron well lid supporting with it lose easily, makes maintenance cost higher.
Have, some casting iron well lids are because quality problems after the weight that receives automobile for a long time, cause breakage easily again, and the accident that often has vehicle or pedestrian to fall in the valve well takes place, and has become the major issue that solution is badly in need of in urban construction.
For solving the problems of the technologies described above, necessary a kind of structure improved buried soft seal formula gate valve that has is provided, to overcome said defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of the utility model is to provide the buried soft seal formula gate valve of low, the easy to operate and tool anti-theft feature of a kind of user cost.
For realizing above-mentioned purpose, the technological scheme that the utility model is taked is: a kind of buried soft seal formula gate valve, and it comprises valve body, encapsulate valve plate, valve rod, valve gap, lining, gland, casing running, lower beam, upper boom, guide pin bushing, top cover, high derrick and well lid; Wherein, said encapsulate valve plate is contained in the valve body; Said valve rod is connected with the encapsulate valve plate through a Stem Mut; Said valve gap is immobilizated in the valve body top; Said lining is set in outside the valve rod; Said gland is connected to the upper end of valve gap; Said lower beam is fixed in the top of valve rod and can actuate valve stem rotates; Said casing running is set in outside the lower beam; Said upper boom is connected with lower beam, and its top is equipped with guide pin bushing and top cover; Said high derrick is arranged on the top of upper boom, and its top is equipped with said well lid.
The buried soft seal formula gate valve of the utility model further is set to: between said lining and valve rod, further be provided with one and open the checkpost cover.
The buried soft seal formula gate valve of the utility model further is set to: the bottom in said high derrick further is provided with an aqueduct, is provided with stone bolt in a side of this high derrick.
The buried soft seal formula gate valve of the utility model also can be set to: outside said upper boom, be arranged with sleeve pipe on, said going up between sleeve pipe and the casing running is provided with some packing rings.
Compared with prior art, the utlity model has following beneficial effect:
1. the buried soft seal formula gate valve direct-burried of the utility model is used for the usefulness of the keying of plumbing and heating pipe in underground, can replace traditional valve well fully, thereby reduces engineering cost; Prevent simultaneously that well lid from losing, stopped the fall casualty accident of well of people, car.
2. operator's operation of can standing on ground, labor intensity is low and convenient.
3. telescopic upward sleeve pipe and casing running can freely be adjusted (20cm) with the sedimentation or the protuberance on ground, do not make valve body stressed.
[description of drawings]
Fig. 1 is the sectional drawing of the buried soft seal formula gate valve of the utility model.
[embodiment]
See also shown in the Figure of description 1; The utility model is a kind of buried soft seal formula gate valve, and it is made up of members such as valve body 1, encapsulate valve plate 2, valve rod 3, valve gap 4, lining 5, gland 6, casing running 7, lower beam 8, upper boom 9, guide pin bushing 10, top cover 11, high derrick 12 and well lids 13; All can be provided with sealing configuration and increase sealing effect in the cooperation place of adjacent two members, the sealing structure can be Sealings such as O-ring gasket; Can adopt modes such as bolt, screw, interference fit to connect between two members that connect; Above-mentioned Sealing and Placement are the common technology means, repeat no more at this.
Wherein, said valve body 1 adopts spheroidal graphite cast iron after the shot-blasting machine cleaning, the preservative treatment of surface spraying nontoxic epoxy resin (plastic-blasting).
Said encapsulate valve plate 2 is contained in the valve body 1, and it is formed by the rubber-coated manufacturing of spheroidal graphite cast iron core body, and its concrete parameter is following: rubber thickness: sealing surface thickness >=2 that the lower edge contacts with valve body 2 millimeter; Contactless part >=1 millimeter; Hot vulcanization adhesion strength >=the 1725kpa of metal and rubber; Peeling test >=12.7N/mm; Rubber coats the back flashboard must not reveal iron.
Said valve rod 3 is connected with encapsulate valve plate 2 through a Stem Mut 31, and this valve rod 3 drives 2 activities of encapsulate valve plate.
Said valve gap 4 is immobilizated in the top of valve body 1, thereby with this Gate-valve sealing.
Said lining 5 is set in outside the valve rod 1, further, between said lining 5 and valve rod 1, further is provided with one and opens checkpost cover 14.
Said gland 6 is connected to the upper end of valve gap 1.
Said lower beam 8 is fixed in the top of valve rod 3 and can actuate valve stem 3 rotates.Said casing running 7 is set in outside the lower beam 8.Said upper boom 9 is connected with lower beam 8, and its top is equipped with guide pin bushing 10 and top cover 11.Outside said upper boom 9, be arranged with sleeve pipe 15 on, said going up between sleeve pipe 15 and the casing running 7 is provided with some packing rings 16, thereby strengthens sealing between the two.
Said high derrick 12 is arranged on the top of upper boom 9, and its top is equipped with said well lid 13.This well lid 13 is exposed to ground usually, and it links together through stainless steel key (not shown) and high derrick 12, closes usually, can be opened by the special messenger when needing operation.Further be provided with an aqueduct 17 in the bottom of said high derrick 12, even if very big rainwater even immersion are arranged at ordinary times, also do not have water, wet goods liquid flows to underground along aqueduct 17.Side in this high derrick 12 further is provided with stone bolt 18, thereby is embedded in this gate valve underground securely.
