Abstract
The utility model discloses a two-way seal sleeve type pipeline compensator which is suitable for various heat distribution pipelines. The two-way seal sleeve type pipe compensator comprises a core pipe, an outer sleeve pipe, etc. The utility model is characterized in that at least two V-shaped sealing rings and wedge-shaped pressure rings are arranged between the core pipe and the outer sleeve pipe. Compared with present various pipeline compensators which are usually used, the pipeline compensator has the advantages of antifriction, high temperature resistance, corrosion prevention, long service life, simple and reasonable structure, good seal property, convenient adjustment and installation, low engineering cost, etc. Waste of manpower, material resources and energy resulting from repair of many times in the process of use is avoided.
Description
The utility model discloses a kind of two way sealed bushing type pipeline compensator of using on all kinds of heat distribution pipelines of being suitable for.
Be widely used in the pipeline compensator on the heat supply engineering at present, mainly several by pipe-type compensator, bellow type compensator, ball compensator etc.Bellow type compensator, its technology are comparatively advanced, but exist the manufacturing process complexity, and cost of production is higher, the defective that compensation rate is little; Ball compensator then can not be installed by straight line, must use in pairs, and floor space is also bigger; And existing old-fashioned bushing type pipeline compensator, its concrete structure is as shown in Figure 2: be to utilize the asbestos rope packing to add graphite etc. to fill in the slit between outer sleeve and the inner core tube, beat reality with hand hammer then, compress with bolted bonnet (BB) again, what have also adds spring compression, yet this kind structural type is in practical engineering application, because sealing material is asbestos, graphite does not have elasticity, forms micro-pore when rising in that pipeline thermal is swollen, cause thermal source to leak, what have then loads onto i.e. leakage because twisting is installed, and therefore, amount of maintenance is very big in the using process, cause manpower, the significant wastage of the material resources and the energy, and the normal production of influence, life heat supply running.
The purpose of this utility model provides a kind of simple and reasonable in order to solve existing deficiency in the above-mentioned prior art exactly, good seal performance, and engineering cost is low, the new casing formula pipeline compensator of Installation and Debugging convenience and long service life.
The purpose of this utility model realizes by following measure:
This two way sealed bushing type pipeline compensator is made up of core pipe, outer sleeve, gland and the stationary gland parts such as bolt on outer sleeve, and twice V-shaped seal ring and wedge type pressure ring at least wherein are housed between core pipe and outer sleeve.
In the utility model, three road V-shaped seal rings and wedge type pressure ring preferably are housed between core pipe and outer sleeve, V-shaped seal ring selects for use the metallo-plastic material to make, and the wedge type pressure ring selects for use cast iron materials to make.
The utility model is compared with existing various pipes compensator and is had the following advantages: simple and reasonable, engineering cost is low, because seal arrangement adopts metallo-plastic and cast iron materials, therefore have characteristics wear-resisting, high temperature resistant, corrosion-resistant, that the life-span is long, the socket joint fit system of V-shaped seal ring and wedge type pressure ring then makes sealability greatly strengthen, and can realize axle, two way sealed radially, and along with the temperature in the pipe is high more, pressure is big more, the tightness of bushing type pipeline compensator is strong more, forms the tight situation that heals of more pressing.After tested, pipeline compensator of the present utility model, its frictional force only is equivalent to 1/5～1/10 of existing old-fashioned pipe-type compensator frictional force.Use the utility model can be saved 50% investment than use bellows, ball compensator, investment than old-fashioned sleeve compensator saving 20%, and saved a large amount of Cost of repair and maintenance and the second investment, thoroughly solved the problem that influences production and normal operation of life and energy waste that causes owing to running, emit, leaking simultaneously.
The drawing of accompanying drawing is described as follows:
Fig. 1 is structural representation of the present utility model (also being the specification digest accompanying drawing).
Fig. 2 is the structural representation of the old-fashioned pipe-type compensator of prior art.
The utility model is done with detailed description below in conjunction with accompanying drawing:
As shown in Figure 1: V-shaped seal ring 5 and castiron wedge type pressure ring 6 that three roads are made by metallo-plastic are housed between core pipe 1 and outer sleeve 2, compress with gland 3 then, by bolt 4 gland is fixed on the outer sleeve 2 again.
Claims (3)
1, the utility model relates to a kind of two way sealed bushing type pipeline compensator, it is made up of core pipe 1, outer sleeve 2, gland 3 and stationary gland bolt 4 on outer sleeve 2 etc., it is characterized in that: twice V-shaped seal ring 5 and wedge type pressure ring 6 at least are housed between core pipe 1 and outer sleeve 2.
2, two way sealed bushing type pipeline compensator according to claim 1 is characterized in that: three road V-shaped seal rings 5 and wedge type pressure ring 6 preferably are housed between core pipe 1 and outer sleeve 2.
3, two way sealed bushing type pipeline compensator according to claim 1 and 2, it is characterized in that: V-shaped seal ring is made by the metallo-plastic material, and the wedge type pressure ring is made by cast iron.
