Abstract
The utility model relates to a water flow check valve for a steam drag harrow. The water flow check valve for the steam drag harrow comprises a valve body, a valve core, a pressure spring and a valve cover, wherein the valve body comprises a water inlet interface and a valve core cavity which are arranged on the same straight line, the valve core is arranged at the junction of the water inlet interface and the valve core cavity, the valve cover comprises a cover body and a water outlet interface with an opening at one end, a water outlet hole is arranged on a bottom board of the water outlet interface, the upper end of the pressure spring is fixedly connected with the valve core, the lower end of the pressure spring is matched with the bottom board of the water outlet interface, the cover body of the valve cover is connected with the valve core cavity in a detachable way to realize liquid-gas sealing. When the water flow check valve for the steam drag harrow is used, the water inlet interface on the valve body is connected with a water inlet pipe, and the water outlet interface on the valve cover is connected with a steam generator. Due to the adoption of the structure, water enters the valve body from the water inlet pipe; under the gravitational action of the water, the valve core moves downwards and leaves a valve core seat; water enters the steam generator through the valve cover; and when no water is in the water inlet pipe, under the action of the pressure spring, the valve core is tightly attached to the valve core seat, therefore, heated water or steam can be effectively prevented from flowing backwards to the water inlet pipe, so the potential safety hazard is eliminated.
Description
Technical field
The utility model relates to the device that a kind of steam drag harrow is used, the water check valve that especially a kind of steam drag harrow is used.
Background technique
Present existing technology, the water inlet interface of steam mop directly is connected with steam generator.Existing problems are: after water got into steam generator, the water expanded by heating also produced steam, can return aqueous reflux or steam entering water inlet interface to occur, had potential safety hazard.
Summary of the invention
The purpose of the utility model is: the current one-way valve that provides a kind of steam drag harrow to use, and it can effectively prevent the aqueous reflux of expanded by heating, stability of flow also can prevent that steam from getting into the water inlet interface, eliminated potential safety hazard.
The utility model is achieved in that the current one-way valve that a kind of steam drag harrow is used, and comprises valve body, spool, pressure spring and valve gap, and said valve body comprises water inlet interface and the spool chamber on the straight line, and spool is arranged on the into intersection of water interface and spool chamber;
Said valve gap comprises the water outlet interface of a lid and an end opening, on the base plate of water outlet interface osculum is arranged;
The pressure spring upper end cooperates with the base plate of water outlet interface with spool fixed connection, lower end, and the lid of valve gap and spool chamber removably connect and reach the liquid hermetic seal.
The current one-way valve that described steam drag harrow is used, its special way is: on the outer wall of said spool chamber outside thread is arranged, internal thread is arranged on the cover body.
The current one-way valve that described steam drag harrow is used, its special way is: also comprise a seal ring,
Said seal ring is arranged between the end of outer shroud dish and lid of valve body.
The current one-way valve that described steam drag harrow is used, its special way is: said spool comprises the core body and the body of rod, the body of rod inserts in the pressure spring, pressure spring upper end and core body against.
The current one-way valve that a kind of steam mop of the utility model is used, in use, the water inlet interface on the valve body is connected with intake pipe, and the water outlet interface on the valve gap is connected with steam generator; Owing to adopt such structure, water gets in the valve body from intake pipe, and the effect of the gravity of water moves down spool, and spool leaves valve core case, and water is in valve gap gets into steam generator; When in the intake pipe when anhydrous, under the pressure spring effect, spool and valve core case fit tightly, and water that can prevent effectively to be heated or steam flow backwards and in intake pipe, eliminated potential safety hazard.
Description of drawings
Fig. 1 is the sectional view of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Current one-way valve as shown in Figure 1, that a kind of steam drag harrow is used comprises valve body 1, spool 2, pressure spring 3 and valve gap 4, and said valve body 1 comprises the water inlet interface 11 and spool chamber 12 on the straight line, and spool 2 is arranged on the into intersection of water interface 11 and spool chamber 12;
Said valve gap 4 comprises the water outlet interface 42 of a lid 41 and an end opening, and osculum 421 is arranged on the base plate of water outlet interface 42;
On the outer wall of said spool chamber 12 outside thread is arranged, on the inwall of lid 41 internal thread is arranged.
Also comprise a seal ring 5,
Said seal ring 5 is arranged between the end of outer shroud dish 13 and lid 41 of valve body 1.
Said spool 2 comprises the core body 21 and the body of rod 22, and the body of rod 22 inserts in the pressure springs 3, pressure spring 3 upper ends and core body 21 against.
In use, the water inlet interface 12 of valve body 1 is connected with intake pipe 6, and the water outlet interface 42 of valve gap 4 is connected with steam generator 7.
Above-described only is the preferential mode of execution of the utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is regarded as the protection domain of the utility model.
