Abstract
The utility model discloses a joint voltage limiting valve, it includes valve gap, valve body, spring, it is used for to tight to be equipped with at least one lug and one on the valve body inside wall the bulge loop of spring, set up the opening on the lug towards the inside draw -in groove of valve body, the valve gap has the column lateral wall, be equipped with on the lateral wall with the fixture block of draw -in groove one -to -one, the spring is located between bulge loop and the valve gap. The utility model discloses utilizing the fixture block on the valve gap fixed with the draw -in groove looks joint on the valve body, when the valve gap is pulled down to needs, only needing just can take out the valve gap after rotatory certain angle makes fixture block and lug stagger totally according to forcing down, inversion operation just can accomplish the installation, and the dismouting is very convenient.
Description
Technical field
This utility model relates to auto-parts field, particularly to a kind of clamping pressure limiting valve.
Background technology
Existing pressure limiting valve valve gap adopts the cooperation of bolt screw to be installed on valve body mostly, when maintenance, dismounting is inconvenience extremely, such as " oil and chemical industry equipment " the 9th phase in 2015, very clear and definite in " valve body compares with valve gap connecting bolt computing formula " that Liu Xingding, temperature wisdom are delivered point out that valve body and valve gap are generally with bolts.
Summary of the invention
The purpose of this utility model is to provide a kind of clamping pressure limiting valve easy to connect.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of clamping pressure limiting valve, it includes valve gap, valve body, spring, described valve body medial wall is provided with at least one projection and one for pushing against the bulge loop of described spring, described projection offers the opening draw-in groove towards valve inner, described valve gap has cylindrical side wall, and described sidewall is provided with and described draw-in groove fixture block one to one, and described spring is between described bulge loop and valve gap.
Optimizing, each described projection has the boss that polylith extends bottom valve gap.
Further, described boss has three pieces of distributions in trident shape.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that this utility model utilizes the fixture block on valve gap to connect and fix mutually with the draw-in groove on valve body, when valve gap pulled down by needs, only need to press bottom flange to rotate to an angle and make fixture block and projection just can be taken out by valve gap after staggering completely, reverse operating just can complete to install, and dismounts extremely convenient.

Structural representation (in figure, arrow represents direction of insertion) when accompanying drawing 1 is that in this utility model, valve gap has just inserted valve body；
Accompanying drawing 2 is the structural representation (in figure, arrow represents the anglec of rotation) during the fully-inserted valve body of valve gap in this utility model；
Accompanying drawing 3 is the structural representation that in this utility model, valve gap is connected with valve body after rotating；
In the figures above: 1, valve gap；2, valve body；3, spring；4, projection；5, draw-in groove；6, sidewall；7, fixture block；8, boss.
Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, this utility model is further described.
As shown in Figure 1, clamping pressure limiting valve includes valve gap 1, valve body 2, spring 3, described valve body 2 medial wall is provided with at least one projection 4 and one for pushing against the bulge loop of described spring, in the present embodiment, projection 4 has two and symmetrical, described projection 4 offers opening towards the draw-in groove 5 within valve body 2, described valve gap 1 has cylindrical side wall 6, described sidewall 6 is provided with and described draw-in groove 5 fixture block 7 one to one, when valve gap 1 is plugged in valve body 2, described spring 3 is pressed between described bulge loop and valve gap 1.Each described projection 4 has the boss 8 that polylith extends bottom valve gap 1.Described boss 8 has three pieces and the distribution in trident shape.
This utility model principle is as follows: when valve gap is installed into valve body by needs, valve gap is pressed direction shown in Fig. 1 and inserts valve body, press again shown in Fig. 2, half-twist (if 3 projections then rotate 60 °) unclamps valve gap subsequently, valve gap will move under spring force outside valve body, as it is shown on figure 3, now fixture block just can snap in draw-in groove, reverse operating just can unload bottom flange, dismounts extremely convenient.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalences made according to this utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
