Problems solved by technology

[0005] The beneficial effect of the present invention is that the valve can not only automatically control the indoor temperature, but also because the outer edge of the bottom of the sealed bellows is sealed in the middle of the valve sleeve by the bottom of the valve cover, it only performs stretching and shrinking movements during operation, avoiding mechanical friction and solving the problem of The problem of leakage caused by the wear of valve stem and seal in the prior art

Embodiment Construction

[0008] The specific embodiment of the present invention sees accompanying drawing. The structure mainly includes valve body (1), piston assembly (2), lower sealing ring (3), return spring (4), valve cover (5), bonnet frame (6), linkage assembly (7), temperature bulb (8), bonnet (9), temperature bulb bellows (10), positioning sleeve (11), linkage sleeve (12), sealing bellows (13), upper seal (14), valve sleeve (15), Valve pressure rod (16); the water outlet in the valve body (1) cooperates with the piston assembly (2) to achieve the purpose of opening or closing the valve; the upper step of the valve pressure rod (16) withstands the inner seal bellows (13) The upper end and the middle part are covered with a return spring (4), and the lower part is connected with the piston assembly (2) through the lower sealing ring (3) through the valve sleeve (15); the outer edge of the lower part of the sealing bellows (13) is covered by the valve cover (5 ) is pressed and sealed on the st...

Abstract

The invention relates to a leak-proof compression bar type temperature control valve, belonging to the technical field of heating and ventilation valves. The control valve is characterized in that a water outlet in the valve body is matched with a piston component for opening or closing the valve, and the lower outer edge of a seal corrugated pipe is compressed and sealed by the bottom outer edgeof a valve cap on a step in the middle of a valve jacket. The valve can automatically control the indoor temperature, and because the bottom outer edge of the seal corrugated pipe is sealed by the bottom outer edge of the valve cap in the middle of the valve jacket, the valve only does extension and contraction movement in working, thereby avoiding mechanical friction and solving the problem of leak caused by abrasion of a valve rod and a sealing component in the prior art.

Description

technical field [0001] The utility model relates to a pressure rod type temperature control valve without leakage, which belongs to the technical field of heating and heating valves. Background technique [0002] The existing indoor temperature control technology mainly uses an automatic temperature control valve installed on the radiator to automatically adjust the flow rate of the heat medium in the radiator to achieve the purpose of controlling the indoor temperature. However, the defect of the existing pressure rod type temperature control valve is: because the valve pressure rod is inserted into the sealing ring as a means of isolating the inside of the valve from the outside world, it will repeatedly move up and down for a long time and rub against it, which will eventually cause the wear of the rubber sealing ring, resulting in the loss of the heat medium. Leakage, causing losses to users. Contents of the invention [0003] The object of the present invention is to...
