Description

Novel temperature control valve core

Technical Field

The utility model relates to a temperature-sensing valve technical field specifically is a novel temperature-sensing valve case.

Background

A temperature control valve is called a temperature control valve for short, is a typical application of a flow control valve in the field of temperature control, and has the following basic principle: the outlet temperature of the equipment is controlled by controlling the inlet flow of a heat exchanger, an air conditioning unit or other heat and cold equipment and primary heat (cold) medium.

But the current hidden danger that has the leakage because of adopting "O" type circle structural seal, the market adopts valve rod and case screw thread driven temperature-sensing valve mostly, in case the structure leaks like this, just must change this valve wholly, brings very big trouble for customer's life, and cost of maintenance is high, is unfavorable for after-sales service.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel temperature-sensing valve case to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel temperature control valve case, includes case, valve body, soft seal, hard seal and water pipe head, the valve body both sides are provided with water pipe head, the inside screw thread through both sides of valve body is connected with the case, the case bottom is provided with hard seal, and hard seal sets up to 60 tapering structures, soft seal is installed with valve body threaded connection department below in the case outside, and soft seal sets up to EPDM O type sealing washer, the case is the same with the thread sealing face and the concentricity of valve body.

Preferably, the valve core is arranged in a detachable structure.

Preferably, the valve body and the water pipe joint are arranged into an integrally formed structure.

Compared with the prior art, the beneficial effects of the utility model are that: the novel temperature control valve core takes the valve body as a thread reference, and the thread of the valve core is in transmission with the leather body to ensure the sealing surface and concentricity, thereby being more beneficial to taper hard sealing; and moreover, the valve body and the valve core are adopted for screw transmission, and only the valve cover and the valve core need to be replaced under the condition of upper cap leakage, so that the sealing structure is simple, rapid and convenient.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a novel temperature control valve core embodiment: a novel temperature control valve core comprises a valve core 1, a valve body 2, a soft seal 3, a hard seal 4 and water pipe joints 5, wherein the water pipe joints 5 are arranged on two sides of the valve body 2, the interior of the valve body 2 is connected with the valve core 1 through threads on two sides, the hard seal 4 is arranged at the bottom of the valve core 1, the hard seal 4 is arranged to be a 60-degree taper structure, the soft seal 3 is arranged below the threaded connection part of the outer side of the valve core 1 and the valve body 2, the soft seal 3 is arranged to be an ethylene propylene diene monomer O-type sealing ring, and the threaded sealing surfaces and concentricity of the valve core;

the valve core 1 is arranged into a detachable structure; the valve body 2 and the water pipe joint 5 are arranged into an integrated structure.

The working principle is as follows: as shown in the area A in the attached figure 1, the valve core of the novel temperature control valve adopts a valve body and the valve core to carry out thread transmission, only the valve cover and the valve core need to be replaced under the condition that an upper cap leaks, and when maintenance is needed, a water inlet valve and a water return valve need to be closed before replacement in the first step; secondly, screwing the hand wheel with force to ensure zero leakage of the valve core; secondly, removing the hand wheel and the clamp spring; fourthly, stabilizing the valve rod by one hand and loosening the valve cover by one hand; and fifthly, replacing the valve cover and the valve rod, and installing and recovering the handle wheel.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
