Abstract
The utility model discloses a guide-type check valve, relates to a check valve used in each pump room aboveground and underground a coal mine, and aims at providing design capable of prolonging the service life of the check valve and improving the use effect of the check valve. The guide-type check valve is characterized in that a valve clack is arranged in a valve body, the valve clack is installed on a connection seat through a connection plate, the connection plate is hinged on the connection seat, an anti-rotation rod is connected to the outer side of the valve clack, and guide claws are connected to the inner side of the valve clack. The guide-type check valve disclosed by the utility model has the following advantages that: due to the design for the guide-type check valve, the main factors influencing the service life of check valve are thoroughly eliminated, the service life of the novel check valve is prolonged by more than 80% than that of the original check valve, and moreover, the closure path of the valve clack is quite ideal under the guide of the guide claws.
Description
Technical field
The utility model relates to a kind of safety check, relates in particular to the safety check that upper and lower each pump house of a kind of coal mine is used.
Background technique
Safety check refers to and relies on medium itself to flow and automatic open and close flap, is used for preventing the valve that medium flows backwards.Safety check belongs to a kind of automatic valve, and its Main Function is to prevent that medium from flowing backwards, preventing pump and drive motor reversion, and the releasing of vessel media.
Safety check is automatic operation, and under the mobile fluid pressure action of direction, flap is opened; When fluid flows, by the flap of coincidence certainly of hydrodynamic pressure and flap, act on valve seat in the other direction, thereby cut off, flow.The use of colliery safety check is very extensive, and upper and lower each pump house of well has the use of safety check.But the safety check that former factory produces is after using several times, and the baffle plate of safety check flap, when running into backwater, often occurs stifled imprecision, occur the phenomenon of leaking not realizing the effect of real safety check.
Summary of the invention
The purpose of this utility model is to provide a kind of raising safety check working life, the design method of lift check valve using effect.
For achieving the above object, the technical solution adopted in the utility model is:
A guiding type safety check, is characterized in that: valve inner is with flap, and flap is arranged on connecting base by connecting plate, and connecting plate is hinged on connecting base, and the outside of flap is connected with anti-bull stick, and flap inner side is connected with guiding pawl.
Guiding type safety check according to claim 1, is connected with four identical guiding pawls above described flap, guiding pawl is " fan-shaped ", and material is steel plate.
The utility model has the advantages that: the design to guiding type safety check, the principal element that affects safety check working life is thoroughly eliminated, improved more than 80% the working life of new-type safety check than former safety check, and the path of closing of flap is very good under the guiding of guiding pawl.

Embodiment
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, flap 4 is above with four guiding pawls 1, and the quantity of guiding pawl 1 is not limited to four.Guiding pawl 1 most preferred shapes is " fan-shaped ".The connection root of guiding pawl 1 on flap 4 is positioned at above the radius of a circle of inner side.
For stressed even, four guiding pawls 1 adopt the Plate Steels big or small, shape is identical to be made.Guiding pawl 1 is welded on a side of water as shown in Figure 2.
The direction that the direction of arrow is water as shown in Fig. 2.Through transformation, safety check flap 4 is transformed, by four guiding pawls 1 of flap 4 inflow sides (inner side) uniform welding, when backwater, through the guiding of guiding pawl 1, under the promotion of medium fluid, flap 4 is closed automatically, and by the sealing of backwater path, and the path that flap 4 is closed is automatically in an ideal path, it is tight that backwater path is closed, effectively using effect and the working life of lift check valve.Flap 4 is bolted on connecting plate 5.In order to prevent flap 4 rotation under the washing away of the current shown in arrow, the outside of flap 4 (back side) is with an anti-bull stick 7.
The utility model valve body 2 inside are with flap 4, and flap 4 is arranged on connecting base 3 by connecting plate 5, and connecting plate 5 is hinged on connecting base 3, and the outside of flap 4 (back side) is connected with anti-bull stick 7, and flap 4 inner sides are connected with guiding pawl 1.Described flap 4 is connected with four identical guiding pawls 1 above, and guiding pawl 1 is " fan-shaped ", and material is steel plate.
Through checking, the safety check using at present, is all the guiding type safety check that flap installs guiding pawl additional.This designs can reduce every year newly to enter safety check expense and save Master Cost and reaches more than 30,000 yuan.
Embodiment recited above is described preferred implementation of the present utility model; not design of the present utility model and protection domain are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in related domain, common engineers and technicians make the technical solution of the utility model, all should fall into protection domain of the present utility model.
