Abstract
The utility model relates to a water-proof sealing device for a cement hydration heat test. The water-proof sealing device comprises a wide-mouth vacuum bottle, a copper pipe and a cork stopper, wherein a sealing rubber ring is sleeved at the suitable position outside a bottle mouth of the wide-mouth vacuum bottle, the cork stopper is plugged in the bottle mouth, a fastener with a thread on the outer circle is sleeved outside the sealing rubber ring, the fastener is connected with a press cover arranged outside the fastener through the thread, a rubber stopper with the copper pipe is inserted into an upper mouth boss of the press cover, and the rubber stopper abuts against the upper end of the cork stopper tightly. The water-proof sealing device solves the difficult problem that the cork stopper and the wide-mouth vacuum bottle are difficult to seal, and achieves the good water-proof sealing effect. In addition, all parts of the water-proof sealing device can be recycled, the service life is long, the liquid environment of a water bath is protected, meanwhile, resources are saved, and great convenience is brought to using by users.
Description
Technical field
The utility model relates to a kind of sealing arrangement, relates in particular to a kind of waterproof seal for the test of direct method hydration heat of cement, belongs to the hydration heat of cement field tests.
Background technology
When using direct method hydration heat of cement testing tool test hydrated cementitious thermal output, make the sealing of wide-mouth vacuum bottle and cork seam of paraffin, in long-term test, find, seam with the paraffin sealing can make paraffin and wide-mouth vacuum bottle generation part separate in the medium-term and long-term immersion of the liquid of constant temperature water bath, make the liquid in the constant temperature water bath enter in the wide-mouth vacuum bottle, when selecting other leakproofing material sealings for use, do not reach desirable effect yet, influence the test of hydrated cementitious thermal output on the one hand, the paraffin chip enters in the constant temperature water bath on the other hand, and the water environment of inside is polluted.
Summary of the invention
The utility model proposes at the problems referred to above, and purpose is exactly to solve a difficult problem that is difficult to seal between cork and the wide-mouth vacuum bottle, reaches the excellent waterproof sealing effectiveness, and free of contamination a kind of waterproof seal for the hydration heat of cement test.
The purpose of this utility model realizes by the following technical solutions:
Be used for the waterproof seal of hydration heat of cement test, it comprises: wide-mouth vacuum bottle, copper pipe and cork, and the outer adapting position of the bottleneck of its wide-mouth vacuum bottle is set with O-ring seal; Innex cork of bottleneck is equipped with cork; The outer cover of described O-ring seal is equipped with the threaded fastener in outer ring; This fastener is connected by the outside gland of screw thread and its, inserts the rubber plug of band copper pipe in the boss suitable for reading of gland.
In the described wide-mouth vacuum bottle sample tube is housed.
The boss suitable for reading outside of described gland also is provided with to press and blocks up, and this pressure is stifled to be connected by screw thread with gland.
Adapting position on the described gland is provided with handle.
The axial cross section of described O-ring seal is wide at the top and narrow at the bottom trapezoidal.
The axial cross section of described fastener is up-narrow and down-wide trapezoidal, and is complementary with described O-ring seal.
Described gland, fastener and pressure are stifled to be stainless steel material.
It is wide at the top and narrow at the bottom coniform that described rubber plug is.
The utility model compared with prior art has following advantageous effect: the utility model can make on the one hand cork jam-pack bottleneck, guaranteed that on the other hand the liquid that can not in the water bath enters into the wide-mouth vacuum bottle, solve a difficult problem that is difficult to seal between cork and the wide-mouth vacuum bottle, reached the excellent waterproof sealing effectiveness.In addition, all members of the present utility model all can be recycled, and long service life when having protected the water bath liquid environment, has also been saved resource, brings great convenience to the user.
Description of drawings
Fig. 1 is sectional structure scheme drawing of the present utility model;
Among the figure: handle 1, rubber plug 2, gland 3, wide-mouth vacuum bottle 4, sample tube 5, copper pipe 6, O-ring seal 7, fastener 8, cork 9 presses stifled 10.
The specific embodiment
Below in conjunction with specific embodiment the utility model is further described in detail; but protection domain of the present utility model is not limited by specific embodiment; be as the criterion with claims; in addition; with under the prerequisite of technical solutions of the utility model, any change or change that those of ordinary skills that the utility model is made realize easily can both fall within the claim scope of the present utility model.
