Abstract
The utility model discloses a matching structure of a valve body and a valve cover of a pressure reducing valve. The main body of the matching structure comprises the valve body and the valve cover; at the connecting position of the valve and the valve cover, internal threads are arranged on the valve body, and external threads are arranged on the valve cover; the valve body and the valve cover are tightly locked together by matching the internal threads with the external threads; and the valve body and the valve cover are directly matched and connected by the threads without needing other parts. The matching structure has the advantages that the processing and the assembling are relatively simple, the cost is saved, simultaneously the locking force of the valve body and the valve cover is constant, the anti-loosing effect is good, the service life is prolonged, the safety performance is improved, and the quality is stable.
Description
Technical field
The utility model relates to a kind of reduction valve, particularly a kind of relief valve body and valve gap cooperating structure.
Background technique
Present domestic like products valve body and valve gap fit form are to do 4 or 6 tapped holes on the valve body, valve gap fitting surface is with it done corresponding through hole, by 4 or 6 screws valve body and valve gap are coupled together, its defective is that valve body need process a plurality of tapped holes, need during assembling many screws are locked, processing is relative loaded down with trivial details with assembling.
The model utility content
At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of make and assemble simple relief valve body and valve gap cooperating structure.
The utility model takes following technological scheme to realize its purpose: a kind of relief valve body and valve gap cooperating structure, its main body is valve body and valve gap, in valve body and valve gap joint, valve body is provided with internal thread, valve gap is provided with outside thread, and valve body and valve gap tightly lock together by internal thread and externally threaded cooperation.
The beneficial effect that adopts the novel technological scheme that provides of this use to reach is: internal thread on the valve body and the processing of the outside thread on the valve gap are simple, valve gap can directly be worked it out by mould, screw thread of processing on the valve body, during assembling both are directly locked, and need not a plurality of screws are locked, assemble simple and convenient and coupling mechanism force is constant, locking effect is good, valve body and valve gap cooperation need not screw, save cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, be a kind of relief valve body and valve gap cooperating structure, its main body is valve body 1 and valve gap 2, joint at valve body 1 and valve gap 2, valve body 1 is provided with internal thread 3, and valve gap 2 is provided with outside thread 4, and valve body 1 and valve gap 2 tightly lock together by the cooperation of internal thread 3 and outside thread 4.Valve body 1 and valve gap 2 directly cooperate, and need not other parts, and processing is also relative simple with assembling, valve gap can directly be worked it out by mould, and screw thread of processing is saved cost on the valve body, because valve body 1 and valve gap 2 directly cooperate, and can't see screw thread and screw, so overall appearance is simply generous, when locking by internal thread 3 and outside thread 4, valve body 1 and valve gap 2 lock by torque spanner, coupling mechanism force is constant, and anti-loosing effect is good, and extend working life, Safety performance improves, steady quality.
Claims (1)
1. relief valve body and valve gap cooperating structure, main body is valve body and valve gap, it is characterized in that: in valve body and valve gap joint, valve body is provided with internal thread, valve gap is provided with outside thread, and valve body and valve gap are by locking together internal thread and externally threaded the cooperation tightly.
