Abstract
The utility model relates to a tank lid with a vent valve. The tank lid comprises a lid body, a valve body upper casing, a valve body lower casing and a valve block. A cavity is formed between the valve body upper casing and the valve body lower casing, the valve block is arranged in the cavity, a small hole is arranged on the lid body, a middle through hole is arranged on the valve body lower casing, and the valve block can move vertically under the effect of buoyancy and forms sealing match with the valve body upper casing. The tank lid with the vent valve has the advantages that air can pass in and out of a water tank freely in a working process of a main machine or a shutdown process of the main machine, a purpose of balanced internal pressure and external pressure of the water tank is achieved effectively, the internal pressure and the external pressure of the water tank are guaranteed to be balanced so that a water circulation system of the main machine can operate normally, and water can not overflow when a water level of the water tank exceeds. The tank lid with the vent valve has the advantages of being simple in structure and convenient and reliable to use. The tank lid with the vent valve can be widely applied to various water tanks requiring balanced pressure by adjusting an installing method and a temperature resistance material appropriately.
Description
Technical field
The utility model relates to a kind of accessory of temperature-regulating mattresses, especially a kind of tank lid with outlet valve.
Background technique
Common temperature-regulating mattresses main frame tank lid is the sealed type tank lid, in use because sealing of lid, water circulation system is in the system of relative closure, because the effect of expanding with heat and contract with cold of air, can make whole water circulation all the time system be in negative pressure and the excessive state of pressure, system is in can't recurrent state, and pressure is excessive can to make again system be in pressure condition, easily makes system because pressure is excessive and damaged leaks.Also there is not at present reliable and effective solution.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of tank lid with outlet valve of effectively resolution system internal and external pressure balance is provided.
The utility model solves the technological scheme that its technical problem adopts: this tank lid with outlet valve, comprise lid, valve body upper casing, valve body lower casing and valve piece, form a cavity between valve body upper casing and the valve body lower casing, the valve piece is located in this cavity, lid is provided with aperture, the valve body lower casing is provided with intermediate throughholes, and the valve piece can move up and down under the effect of buoyancy, and is sealed and matched with the formation of valve body upper casing.
As preferably, described valve body lower casing is provided with the guide sleeve that the valve piece is play the guiding role.
As preferably, described valve body upper casing be provided with the valve piece on the cone face form the face that the location cooperates.
As preferably, be provided with O shape circle one between described lid and the valve body upper casing.
As preferably, described valve piece is provided with the O shape circle two that cooperates with the valve body upper casing.
As preferably, described lid is provided with the outside thread fixing with water tank outward.
The effect that model utility is useful is: the design is no matter be in the working procedure of main frame or in the process of main frame at startup-shutdown; air can both free in and out water tank; effectively solved the internal and external pressure balance problem of water tank; both guaranteed the internal and external pressure balance of water tank; so that the water circulation system of main frame can normally be moved; guaranteed that again water tank when the water level carry, can not cause overflowing of water.The design has simple in structure, and easy to use, reliable advantage by suitable adjustment installation method and temperature-resistant material, can be widely applied to various requirement and keep on the pressure balanced tank lid.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structural representation of the present utility model when not contacting water level;
Fig. 3 is structural representation of the present utility model when touching water level;
Description of reference numerals: lid 1, valve body upper casing 2, valve body lower casing 3, O shape is enclosed one 4, O shape and is enclosed 25, valve piece 6, aperture 7, intermediate throughholes 8, guide sleeve 9, outside thread 10, face 11.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: such as Fig. 1, this tank lid with outlet valve comprises lid 1, valve body upper casing 2, valve body lower casing 3 and valve piece 6, forms a cavity between valve body upper casing 2 and the valve body lower casing 3, and valve piece 6 is located in this cavity.In the centre of lid 1 aperture 7 is arranged, intermediate throughholes 8 is arranged on the valve body lower casing 3, during water level in tank lid does not touch water tank, because valve piece 6 is in position as shown in Figure 2 under action of gravitation, air can free in and out casing by the intermediate throughholes 8 of the cavity between aperture 7, valve body upper casing 2 and the valve body lower casing 3, valve piece 6 and valve body lower casing 3 on the lid 1, thereby makes the inside and outside pressure of water tank keep balance.When water level in the water tank touches valve piece 6, because the very light material that valve piece 6 adopts is made, can float on the surface, under buoyancy and effect, valve piece 6 can float with the rising of water level in the water tank, under the leading role of the guide sleeve 9 in valve body lower casing 3, valve piece 6 can float in the center hole position of valve body upper casing 2, guaranteeing can be not crooked, near upper limit the time, cone face and the face 11 on the valve body upper casing 2 by valve piece 6 are accurately located, and have guaranteed the reliable sealing of the face 11 on O type circle 25 and the valve body upper casing 2, as shown in Figure 3.Lid 1 is by O type circle 1 and 2 sealings of valve body upper casing, and valve body upper casing 2 and valve body lower casing 3 carry out Plastic Welding by high frequency, and lid 1 is fixed by outside thread 10 and water tank, has so not only guaranteed the convenience of installing but also has guaranteed that sealability is reliable.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
