A product function and application Self-Three temperature control valve (hereinafter referred to as links thermostat valve) is a charged without relying on external energy and medium temperature and automatically adjust their own energy-saving products. It combines the measurement, implementation, control functions into one, widely used in heat transfer equipment, air conditioning and all kinds of diesel engines, air compressors, lubrication equipment, gas turbines, generators and other equipment, oil cooling system, water temperature control. 2 Work Three thermostat valve is based on the incompressible fluid and thermal expansion and contraction principle to work. 3 Features and specifications 3.1 features: (1) Three thermostat valve of a sense of warm sensitive internal components are in the body, so no external sensing device; (3) Three thermostat valve three types of import and export a variety of installation options and the pipe is connected; ( 3) Three small size, light weight thermostat valve; (4) Three thermostat valve without external energy, the use maintenance; (5) thermostat of high precision and smooth; (6) thermostat with emergency manual valve control device. 3.2 Specifications: DN15 ~ 200mm. 4, divided into categories according to type of valve structure: ⑴ rotating valve (≥ DN50); ⑵ slide valve (≤ DN50). Five links thermostat valve design parameters and temperature regulation scope 5.1 The design parameters in Table 1. 5.2 Temperature adjustment range in Table 2. 5.3LZF rotating valve and thermostat valve installation types in Table 3. 6 points of design selection (1) first identified the controlled media is oil or water. (2) calculated by control of the media flow m3 / h. (3) According to the controlled media and the design flow to select the links thermostat valve diameter. (4) According to the body material (bronze or cast iron T), the connection form (F flange, G pipe thread, ZG tapered pipe thread), the valve structure type (Z rotating valve, H slide valve), temperature regulation range and installation type (see Table 3) to determine three-way valves model. (5) According to three different fluid flow valve port, three thermostat valve can be used to merge (Figure 1) or shunt (Figure 2) control of occasions. (6) Combined type thermostat valve is the role of links to two different temperatures of fluid through the valve between the temperature before mixing into the third between the fluid temperature, this valve has two import (B entrance for the high-temperature, C for the low entrance) and an exit (A), temperature sensing devices installed in the exit (A) Department. Split thermostat valve is the role of links to a fluid through the valve divided by the proportion of two-way, when the valve is closed an outlet at the same time on the open another exit, this valve has an entry (A) and two exit (B to pass back to port, C port for streaming cooling). (7) Three thermostat valve can replace a two-way valve and a links over. (8) Three rotating valve type thermostat valve installed in six (Table 3), adapted for connection to any pipe, installation of the actual pipe connection type selected according to the system. (9) links thermostat valve can be installed anywhere, but the emergency manual device easy to operate surface should be installed at the location. (10) to prevent the media from jamming or blockage of impurity, three thermostat valve should the valve before setting filters.
