Abstract
A shrinkage-proof water tank belongs to a water tank, in particular to a water tank which can prevent the shrinkage and deformation when water tank in a negative pressure state after improved. The shrinkage-proof water tank comprises a water tank body, a water inlet pipe, a water outlet pipe and a vent pipe, which is characterized in that a one-way air intake valve is fixedly installed on the water tank body. The water tank which is installed with the one-way air intake valve can guarantee the pressure in water tank balance under the condition that the water inlet pipe and the vent pipe are blocked to prevent the shrinkage of the water tank. The structure of the one-way air intake valve is simple and light, and has low cost, does not affect the appearance and construction cost of the water tank, and is convenient and practicable, which is especially suitable to be used in areas which are easy to freeze in winters.
Description
Technical field
The utility model belongs to a kind of water tank, can prevent to be in negative pressure state in the water tank after especially a kind of improvement and causes the water tank of taking out flat distortion.
Background technology
The water tank that uses substantially all has water inlet pipe, outlet pipe at present, also stack can be set in order to guarantee the normal draining of water tank.If water tank is operation out of doors, in the cold in the winter time weather that freezes, the water inlet pipe mouth of water tank and stack place will freeze, with its shutoff, after the normal draining of gutter is with the water emptying in the water tank, air pressure in the water tank is lower than outside atmosphere air pressure, and water tank is taken out flat owing to negative pressure causes, influence outward appearance, if take out flat serious, to cause the water tank flattening deformation to break, and not only influence outward appearance and also can leak, hinder the operate as normal of water tank.
Summary of the invention
Technical problem to be solved in the utility model is exactly to cause that after the water inlet pipe mouth of water tank and stack shutoff water tank takes out flat problem, and a kind of improved flat water tank that can prevent to take out is provided.
The utility model is made up of tank box, water inlet pipe, outlet pipe, stack, it is characterized in that being installed with on the tank box breather cheek valve.
This breather cheek valve is made up of the spool in valve body and the valve pocket, and the lower end is provided with air inlet in the spool, and the spool periphery is provided with helical spring, the sealing rubber is set encloses on the spool with on the ring surface that valve body contact.When the atmospheric pressure in the water tank during less than atmospheric pressure, atmospheric pressure promotes spool and moves downward, and the pore on the spool is shifted onto in the water tank, and bulge loop on the spool and valve body bayonet socket prevent that spool breaks away from from valve body, air enters water tank by the spool pore and makes the equilibrium of water tank inner and outer air pressure, and it is flat to avoid water tank to take out.When the water tank inner and outer air pressure was balanced, spool was stuck on the valve body by helical spring, and pore is closed in the valve body, can be to water tank inflation or exhaust.
External thread structure is arranged in the junction of this breather cheek valve and water tank, with its with water tank on the internal thread that is provided be tightened and be connected, perhaps breather cheek valve directly is welded on the water tank, perhaps undertaken fixedly connected by draw-in groove.
This water tank that is installed with breather cheek valve, can guarantee under the situation of the water inlet pipe mouth of water tank and stack shutoff, to keep the equilibrium of water tank internal gas pressure, prevent that taking out of water tank is flat, and breather cheek valve is simple in structure, light, cost is low, does not influence the attractive in appearance and cost of water tank, convenient and practical, use in the area that is particularly suitable for freezing easily winter.
