Embodiment Construction

[0034] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0035] After a series of experimental verifications, the inventor found that when the four-way valve of the prior art is in use, during the reversing process from the OFF side to the ON side, the force state of the slider 2' is as follows: Figure 4 shown. The slider 2' receives the driving force F1 provided by the connecting rod, and its stress point is located at the horizontal position where the connecting rod contacts the slider 2'. In addition, the slider 2' is also subjected to the friction force f of the contact surface between the slider and the valve seat during the reversing process. 'The thrust of the slider 2' and the reverse friction f of the valve seat 1' are not on the same lev...

Abstract

The invention provides a reversing valve and a sliding block of the reversing valve. The sliding block of the reversing valve comprises a sliding block body (10), and the sliding block body (10) is provided with a communication cavity, a sealing face and reversing contact faces (11); the sealing face is around the periphery of the communication cavity, and the reversing contact faces (11) are arranged at the two ends, in the movement direction of the sliding block body (10), of the sealing face; and the sliding block further comprises a drainage structure which is arranged on the reversing contact faces (11) and comprises a first drainage opening (21) and a first drainage groove (22). The extending direction of the first drainage groove (22) crosses with the movement direction of the sliding block body (10), and the first drainage opening (21) is arranged on the edge of the sliding block body (10) so as to drain fluid in the first drainage groove (22) to the outer portion of the sliding block body (10). According to the technical scheme, the problem that in the prior art, during reversing, shaking exits is effectively solved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a reversing valve and a slide block thereof. Background technique [0002] The reversing valve in the prior art, taking the four-way valve as an example, its structure is as follows figure 1 As shown, it mainly includes valve seat 1' and slider 2'. The four-way valve is widely used in the field of air conditioning. In this field, due to the deepening awareness of energy saving and environmental protection, energy-saving products such as frequency conversion air conditioners have been developed rapidly. At present, frequency conversion air conditioners have become mainstream products in the market. Therefore, the performance requirements of the four-way valve applied to the frequency conversion air conditioner are getting higher and higher, and it is required to match the performance of the frequency conversion machine. Inverter air conditioner unit is characterized by its wide w...
