Technical Field

The utility model belongs to the technical field of the temperature-sensing valve, a temperature-sensing valve is related to, especially, relate to a radiator adjustable flow temperature-sensing valve.

Background

The temperature control valve is mainly applied to a heating and ventilation system and mainly comprises a valve body, a valve seat, a flow regulating seat, a valve core, a temperature bulb and the like. The upper end and the lower end of the existing valve body are respectively provided with an installation end and a water inlet end, a water outlet end is arranged on the lateral side of the valve body, a water passing hole is arranged between the installation end and the water inlet end and is positioned below an inlet of the water outlet end, the valve seat is fixed on the inner side of the installation end, the flow regulating seat is positioned on the inner side of the valve seat, the lower end part of the flow regulating seat is of an annular structure, a plurality of water passing notches with different sizes are formed in the periphery of the lower end part of the flow regulating seat, the lower end part of the flow regulating seat covers above the water passing hole, the lateral part of the flow regulating seat shields the inlet of the water outlet end, therefore, water flow needs to pass through the water inlet end to enter the flow regulating seat and enter the water outlet end from the notch right opposite to the water outlet end, and the effect of controlling the flow can be achieved by rotating the flow regulating seat to switch the water passing notches with different sizes. The case passes through the valve rod and wears to establish in the inside of flow control seat, and the valve rod upper end is connected with the thermal bulb, and after meetting the temperature and rising, the thermal bulb can promote the valve rod and let the case support and lean on and make it seal on crossing the water hole.

The existing temperature control valve has the following problems: the flow regulating seat is not smooth in rotation, because the flow regulating seat is limited on the inner side of the valve body through the valve seat, contact surfaces which are mutually abutted inevitably exist between the flow regulating seat and the valve seat, and the flow regulating seat which needs to rotate is not smooth in rotation due to the mutual contact matching of the contact surfaces after the flow regulating seat and the valve seat are pressed and mounted.

Disclosure of Invention

The utility model aims at the above-mentioned problem that prior art exists, a but radiator flow control by temperature change valve is proposed. The technical problem that a flow adjusting seat on an existing temperature control valve cannot rotate smoothly is solved.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides an adjustable flow temperature control valve of radiator, includes the valve body, be provided with the disk seat on the valve body, the inboard rotation of disk seat is provided with the flow control seat, the lower extreme of flow control seat has and stretches out that the disk seat is outer and is annular flow control portion and flow control portion up end can form to keep out with the bottom of disk seat, its characterized in that, there are a plurality of even lugs in interval along its circumference protrusion on the up end of flow control portion, the bottom of disk seat supports and leans on the up end of convex part.

The outer diameter of the flow adjusting portion at the lower end of the flow adjusting seat can be large and can be abutted against the bottom of the valve seat, a plurality of convex blocks protrude from the upper end face of the flow adjusting portion, the bottom of the valve seat is abutted against the top face of the convex blocks, and the bottom of the valve seat is in contact with the top face of the convex blocks when the flow adjusting seat rotates. And if the excessive displacement of flow control seat and the cooperation between the lug are too inseparable in the equipment, can be worn and torn a little along with the top of flow control seat number of times increase lug, the flow control seat rotates and also can become smoothly after the lug wearing and tearing.

In the above radiator flow-adjustable temperature control valve, an annular portion protrudes from an outer peripheral surface of the flow adjustment seat, which is located close to the flow adjustment portion, the annular portion is in clearance fit with an inner side surface of the valve seat, and inner side portions of all the protruding blocks are connected to the outer peripheral surface of the annular portion.
